‘Statistical blindness’, and importance of numbers – Football365.com

Friday, February 17th, 2017

Date published: Friday 17th February 2017 10:45

Before wrapping up our series, I want to revisit an example from last week, for two reasons: 1) it shows the value of Expected Goals, and 2) it shows that even stats-conscious people (in this case, me) can miss the main point.

Last week we looked at the Crystal Palace Sunderland game, which finished 0-4, but 1.6 0.9 in expected goals. I noted that the xG totals were misleading, because Sunderland had scored several not-so-easy chances, then sat back and let Crystal Palace attack. What I should have added was that the xG were in one sense not misleading at all: they showed that Sunderland won big not by brilliant overall play, but by brilliant finishing. And as weve seen several times in this series, you cant rely on brilliant finishing to carry you for very long.

In other words, Sunderlands 0.9 xG tells us that as decisive as the victory was, it didnt change one of their underlying problems: the failure to create good chances. The next week against Southampton, one of the best defensive teams in the league, they wound up with a minuscule 0.2 xG and, unsurprisingly, no goals at all.

And now to wrap up, because the counter says F365 has let me spend over 10,000 words on football stats. But to say weve only scratched the surface is putting it very mildly. Football stats are a burgeoning field, and literally every day there are new ideas worth reading about. New measures are developed on a regular basis, many of which we havent even had the time to mention here. The one thing you can be sure of with football stats is that therell always be something more to learn.

Even better, many of the chief practitioners show and discuss their work publicly, and are more than willing to answer questions and share their thoughts. There are a number of excellent writers in the field, who can explain things far more complex than weve mentioned here, and write far more entertainingly doing it. There are also several good analytics podcasts, where you can hear intelligent people kick around interesting ideas, and have fun doing so.

Wheres the best place to go for football analytics? Surprisingly, its Twitter. Virtually all the experts have accounts remarking on current developments, and all provide links to the longer articles with the detailed analysis thats the meat of the subject. Here are links to some of the most prominent figures in the field, all of whom are worth reading on a daily basis:

Michael Caley, Paul Riley, Simon Gleave, Ted Knutson, James Yorke, Ben Pugsley, Mark Thompson, Mike L. Goodman, Thom Lawrence, Ben Mayhew, David Sumpter, Sander, and Dustin Ward.

Theres also a great site called Statsbomb which, although not as active as in the past, has an outstanding archive of articles. Its the site that first got me interested in analytics.

I assume anyone whos read this far has some interest in stats. But for all that they show us, we have to remember they dont have all the answers. Last year was a case in point: the stats kept saying that Leicester would fade. Around the middle of last season, having watched all the games to that point, and looked closely at the stats, I decided with self-important assurance that Spurs would win the title.

But it gets funnier. At a gathering of statisticians around the same time, somebody took an informal poll of about ten attendees on who would win the title. Going by Expected Goals and other numbers, half of them picked Arsenal.

So theres a condition which we can call statistical blindness. Stats people sometimes say Trust the numbers, not your eyes, but your eyes are there for a reason. Stats are an aid, sometimes an excellent aid, to understanding. They can tell you what to look for. But you still have to look, and you have to spot the things that stats cant reach.

To close, thanks to all the people who had kind things to say about this series. And thanks to those too who had less than kind things, because they remind you what really counts. Football is first, last, and always about love. I loved the game for almost fifty years before I even suspected there could be such a thing as football stats, and if all the numbers disappeared tomorrow, Id love it just as much. But for me, stats engage the mind in all sorts of fascinating ways. And when the mind and heart go together, theres a special kind of joy.

Arizona Woman’s Blindness Miraculously Cured Through St. Charbel – National Catholic Register (blog)

Arizona Woman's Blindness Miraculously Cured Through St. Charbel

Within 48 hours after visiting the relics of St. Charbel, her eyesight was completely restored to 20/20 vision. The remarkable and sudden healing was confirmed later by several physicians.

The joy of a Phoenix parish is spreading along with thenews of 30-year-old parishioner Dafne's Gutierrez'scomplete cure of blindness.

The reported miracle of the wife and mother of three is bringing people from around the country to visit St. Joseph Maronite Catholic church in Phoenix, Arizona.

When she was just 13 years old in 1999, Dafne was officially diagnosed withthe medical condition, idiopathic intracranial hypertension (IIH). One effectof thiscondition can be anothercondition called papilledema, where the pressure in the brain is greatly increased. This pressure affectsthe optic nerves, which in some cases such as Dafne's eventuallyresults in complete blindness.

The various medications and treatments which were tried for Dafneall failed. In 2014 theeyesight in her left eye deteriorated dramatically. Her physicians tried two separate surgeries, installing different types of shunts in an attempt to drain and reduce the pressure in her brain, butthese too failed, leading to complete blindness in her left eye. Meanwhile the sight in her right eye was also deteriorating, and she was declared legally blind. She was soon in total darkness, saying in 2015 that she could look directly at the sun and not see any light whatsoever. She also experienced "vise-like" headaches, seizures, tinnitus (ringing in the ears), vomiting, and dizziness. Her doctors declared her blindness to be "permanent and medically irreversible."

Dafne's blindness left her unable to care for her three young children, which completely broke the young mothers heart. On January 7, 2016, "so as to not be an additional burden on her family", she was approved for admittance to a nursing home, because "she could not take care of herself or her children, due to her blindness and seizures", and was scheduled o be admitted soon. "What hurt me the most was not being able to see my children again," she said.

Around the sametime last January 2016, Dafne heard a Spanish radio news report that the first class relics of St. Charbel (or Sharbel) Makhlouf were on a pilgrimage honoring the Lebanese saint's 50th beatification anniversary, and were going to be coming to a nearby church St Joseph Maronite Catholic Church in Phoenix for the weekend of Jan. 16-17.

Neither Dafne or her family had ever heard of this saint. Yet interestingly, later that same day Dafne's sister-in-law called and told her she'd seen an announcement about the visit of the relics, and suggested Dafne and her husband go with her. So theblind mother of three was taken to visit the bone relics of miracle worker St. Charbel during a special veneration and healing service at St. Joseph Church.

Dafne prayed on the way to the church."Please God heal me if not for me, then do it for my kids!I'm tiredI'm tired of going to You praying and asking You to heal me...I am giving in. If You don't want to do it for me, then do it for my kids. That is the way I went in [to the Church] I'm giving in to You. Do it for my kids"

Once at the Church she prayed to God, and then to St. Charbel: "I don't know who you are, but please help me."

After Mass celebrated by parish priest Fr. Wissam Akiki, and the veneration of St. Charbel's relics, her sister-in-law helped her to the confessional. Fr. Akiki was told about her blindnessand blessed her with holy oil touched to the first-class relic of St. Charbel, praying specifically for her to be cured. "I put my hand on her head, then on both eyes, and I asked God to heal her through the intercession of St. Charbel. Fr. Wissam told her that he would be praying for her and that he believed her vision would be restored. Dafne said she "felt very strongly that someone was standing next to me on my right side." Afterwards the priestsaid to Dafne's daughter: "Don't worry, your mom will see again."

After the prayers and blessing with the relic, Dafne asked her sister-in-law, "Who was that standing next to me, on my right side?"Her sister-in-law said,"There was no one standing next to you other than Fr. Akiki." To this day, Dafne is not sure who was standing next to her at that moment, but is sure"someone" was there.

"From that moment" Dafne's stated "I started to feel different. I can't explain it but my body felt different". The next day, Sunday January 17th, 2016, she again went to St. Joseph Church for the 3:00 p.m.Mass and to once again venerate the relic of St. Charbel.

That same Sunday evening at 4:00 a.m. she suddenly awoke with her eyes burning. "They were like burning really burning," and her head hurt "like after an operation." She woke her husband upexclaiming that her eyeswere burning. He asked how that was possible since she had no sensation in her eyes. He then put his hands on her eyes and noticed they felt hot and he said, "They are vibrating and moving" and he also noticed a strong smell like "burning meat". Dafne then realized that she could actually see her husband very vaguely like a shadow. She shouted, "I can see you! I can see you with both of my eyes! I started crying... I wiped my eyes and then opened them again to see if I really could see, and I could."

"I could not believe it. I did not want to close my eyes, she stated afterwards in an interview. My children were shouting: Mom can see! God healed mom!

Within 48 hours (precisely three days after her weekend visit to venerate the relics) her sight was completely restored to 20/20 vision. The remarkable and sudden healing was confirmed that day by an ophthalmologist, and later by several other physicians.

In a statement, Doctor Anne Borik, D.O. stated:

Medically speaking, what is interesting and what captured my interest in this [case] is that you don't see resolution of vision in 48 hours from a long standing optic nerve problem such as Dafne had. My job as a medical physician is to try to find out how this happened medically. We discussed this case with a neuro-ophthalmologist, and also an outside consultant reviewed the entire case, and basically there is no [medical] explanation how Dafne Gutierrez's vision was one day completely blind, and then 48 hours later was restored to normal ...And so based on this information, we as a medical community in reviewing this case cannot explain this medically.

At the very least, the physicians felt that even if she had regained some of her eyesight, there should have been some permanent damage and vision loss in at least her left eye, for that eye had been affected for twoyears. It is expected that there should be at least some optic nerve damage, and that there is simply no medical explanation for a complete restoration of 20/20 vision in both eyes.

"Faith and confession" is what Dafne Gutierrez continues to repeat time and time again when asked about her healing. "I was desperate when I walked into St. Joseph Maronite Catholic Church. Ifelt like God never heard me before, but this time was different, just different. For me to be able to see and read the papers [medical reports] that say that I would never be able to see again...It is such a blessing!"

Exactly one monthafter Dafne's sight was restored,a special Mass of thanksgiving and blessing with the holy oil of St. Charbel took place at St. Joseph Church on February 18, 2016, and was presided by Bishop Abdallah EliasZaidan, Maronite Catholic bishop of Los Angeles, California.

Daffne spoke tothe crowd who had gathered to give thanks to God for her healing through the intercession of St. Charbel: "All the doctors have said: 'There is no explanation'.....God healed me."

In an interview on YouTube, she encouraged everyone: "I just want to keep on telling everybody; Don't lose faith. God does exist. Just have faith ... [go to] confession. Don't lose hope."

Sr Charbel Makhlouf (1828-1898) was a Maronite Catholic monk from Lebanon who died on Christmas Eve at age 73. He spent the last 23 years of his life in a rugged cabin in complete solitude, with poor heat and the bare necessities of life, and was known for his practice of penance and mortifications, eating very little and sleeping on the ground.

Three days after his death he was buried in the monastery cemetery, and for the next 45 nights his tomb was surrounded by a dazzlingly bright light. As the days passed this phenomenon was witnessed by an increasingly large number of local villagers who informed the religious Maronite monastery, none of whom could provide an explanation. Permission was sought from the ecclesiastical authorities for the monks body to be exhumed. Four months after his death permission was obtained, and upon the exhumation his body was found to be completely incorrupt, even thoughhe had been buried in the ground without a casket.Charbel was given fresh clothing before being placed in a wooden coffin in a corner of the monasterys private chapel.

Soon a strange liquid was found exuding continually from the casket, coming from the pores of his body. Described as a mixture of fluid and blood, it continually flowed from his remains day and night. Soon, a local custom began where pieces of cloth soaked in this fluid were soon being distributed as relics, and were being credited with effecting cures. To this day this custom of "holy oil" touched to the relics of St. Charbel used as a blessing is still a very common practice of the faithful, as was used in Dafne's healing.

My Notes On Notes On Blindness – Huffington Post UK

Thursday, February 16th, 2017

It was such a privilege to be part of the 2012 Paralympics and to witness what felt like a breakthrough at that time. Disability was no longer swept aside in subdued tones but talked about openly. Even celebrated! It was amazing to see the pride everyone had in the athletes and their incredible achievements.

Now, more than four years later, another amazing Paralympics has passed and both events have left a much improved legacy. But sadly, there remains an awkwardness surrounding disability. Especially, from my perspective, of visual impairment. I hope it's true that more people have now been encouraged to approach the person in a wheelchair. But my personal experience tells me that there is still a vast lack of understanding when it comes to blindness.

I have always been a passionate advocate of open discussion and the promotion of visual impairment awareness and this is clearly what John Hull has done with his remarkable film. I've seen and read much that tried to make visual impairment understood by the sighted world, but I have never found any to be as effective in humanising visual impairment as the BBC's Notes on Blindness.

The onset of my gradual sight loss began when I was five, bringing with it a huge range of emotions to deal with - along with people's reactions. I had to come to terms with my sight loss as I entered my teenage years. I do not appear visually impaired, and at times I have been treated as an imbecile, or a fraud.

So hearing John Hull explain, in his own words, the sensation of going blind and the internal battles that come with it was incredibly moving for me. As John lost his sight, so many of his stories and moments resonated deeply. I understood when he said "Every time I wake up, I lose my sight", describing how he had more sight in his dreams. I often find I wake feeling sure that in my dream I was fully sighted, like when I was a child. I was so pleased to hear it so eloquently described by John.

When John describes a strange incidence of meeting a faith healer, who told him that his sight was 'dependent on his will', this felt familiar too. It is one of the more extreme reactions to finding out someone is visually impaired, but actually far more common than you think. I myself have been 'healed' three times!

But this and more common suggestions like "Can't you just wear glasses?" remind me how important it is to keep pushing to create an awareness of visual impairment.

I was thrilled to see this insightful programme and feel the BBC have managed to create something that makes visual impairment relatable. I wish that, rather than making uninformed comments people would feel free to actually ask about the extent and nature of my condition and John Hull has helped to open that door.

It showed the daily practical battles we fight - which for John, was being unable to access books and data in an accessible format, and for me include being unable to drive to fetch a pint of milk, or the fact that reading takes me four times as long as my fully sighted counterparts. And it evocatively highlights how people of all ages can struggle with accepting their visual impairments.

Over a third of older people living with sight loss suffer with depression, which is an issue not often discussed or considered. And more than two million people in the UK live with sight loss. That's 1 in 30, and the figure is rising.

But I was pleased that the film also showed really positive things that many with disabilities will understand - like their relationships with family and friends. When an able-bodied person is married to a disabled person, it doesn't mean that they take the roles of 'carer' and 'patient'. It was incredibly refreshing to see the marriage between John and Marilyn as a partnership - often how it is in real life.

John completed his film with a simple quote, which I'd like to share to complete this blog "To gain our full humanity blind people and sighted people need each other."

*** Notes on Blindness will be on BBC Four, Thursday 16th February, 9pm. Notes on Blindness will be shown with a choice of viewing experiences for the visually impaired audience, available for the first time across BBC Four, Red Button and BBC iPlayer.

A version with enhanced sound will be available from 9pm tomorrow. Find out more about the versions here.

Scientists May Have Solved The Mystery Of Nodding Syndrome – NPR

Thursday, February 16th, 2017

A child with nodding syndrome waits for treatment at an outreach site in Uganda's Pader district.

Scientists may have solved the mystery of nodding syndrome, a rare form of epilepsy that has disabled thousands of children in East Africa.

The syndrome seems to be caused by the immune system's response to a parasitic worm, an international team reports in the journal Science Translational Medicine. And they think it's the same worm responsible for river blindness, an eye infection that's also found in East Africa.

The finding means that current efforts to eliminate river blindness should also reduce nodding syndrome, says Avi Nath, an author of the study and chief of the section of infections of the nervous system at the National Institute of Neurological Disorders and Stroke.

The adult form of the O. volvulus worm, which causes river blindness and may also be responsible for nodding syndrome.

"We can prevent new infections even if we can't treat the ones who already have nodding syndrome," Nath says. Drugs can kill the parasite in its early stages.

Nodding syndrome usually strikes children between 5 and 16 who live in rural areas of northern Uganda and South Sudan. Their bodies and brains stop growing. And they experience frequent seizures.

"These are kids, young kids, you would expect that they should be running around playing," says Nath, who visited Uganda several years ago. "Instead, if you go to these villages they are just sitting there in groups," so villagers can keep an eye on them.

The epileptic seizures weaken muscles in the head and neck. "So their heads tend to fall forward," Nath says. "And because that happens repeatedly as part of the seizure, it is termed nodding syndrome."

Researchers have struggled to find a cause for the syndrome since it was first documented in Tanzania in the 1960s. "We thought it might have to do with toxins, chemicals in the environment or nutritional deficiency," Nath says.

But the only clue that seemed to hold up was that affected children lived in areas where river blindness was common. This clue was puzzling, though, because even though nodding syndrome is a brain disease, the parasite that causes river blindness doesn't seem to infect the brain.

After returning from Uganda, Nath decided to search for an explanation.

"He pulled all of the lab together as a team and asked us to each investigate different components" of the syndrome, says Tory Johnson, an assistant professor of neurology at Johns Hopkins who was working for Nath at the time. She is also an author of the new study.

Johnson's assignment was to see whether the body's own immune system might play a role. So she began screening blood samples from people with nodding syndrome.

Other scientists had also looked for an immune response. But Johnson's search was much more extensive. "We looked at everything that was available," she says.

And eventually, she found something.

Nath remembers being in a meeting one day when Johnson appeared suddenly. "I saw her waving at me and I'm like, 'Okay, what happened?'" he says.

Johnson had discovered that in people with nodding syndrome, the immune system was targeting a protein found in certain muscle cells. It looked as if the body was attacking itself.

The question was whether the immune system's attack also included the brain. So Johnson started looking to see whether the targeted protein was in brain cells.

"And lo and behold she found that yes, it was not only present in the brain, there were actually large amounts of it present in neurons," Nath says. "So the story really came together very nicely."

The full story, the team's hypothesis, goes like this:

When a person is infected with the river blindness parasite, the immune system begins sending antibodies to attack the invader. These antibodies identify their enemy by looking for a specific protein in the parasite's cells.

Unfortunately, the target protein in the parasite looks a lot like a protein found in certain brain cells. So these brain cells become unintended casualties of the body's efforts to protect itself.

The discovery shows why it's important to treat children soon after they are infected with the parasite, Nath says. That might prevent an immune response that attacks the brain. And it would mean that the parasite can't be spread from person to person by black flies.

Because nodding syndrome appears to be the result of an immune response, Nath says, it may be possible to limit brain damage in some children by using drugs that tone down the immune system response.

The finding also raises the possibility that parasites, or other infections, are causing epilepsy in the U.S. and other countries, Nath says.

"We know there are a large number of immune-mediated epilepsies," Nath says. "But the underlying cause is not clear."

And there are plenty of parasitic infections in the U.S. Pinworms, for example, infect millions of children each year.

It's possible that some of these infections are leading to epilepsy, Johnson says. "We don't know because we haven't looked yet."

The CSS and Sea Blindness – Pakistan Today

Wednesday, February 15th, 2017

The first Central Superior Services (CSS) examination under revised syllabus was conducted earlier this year. Only 202 out of 9643 candidates qualified the written examination. These successful few will now undergo medical and psychological tests which are likely to cause further screening. In terms of percentage, the success rate in written examination shows a depressing 2.09. While the result puts the countrys education system in poor light, the purpose of this discourse is the want of a crucial yet missing aspect in revised curriculum of the CSS examination which is the National Maritime Sector.

For instance, the national maritime sector encompassing both, economic and military dimension and developments in the Asia-Pacific region are little known subjects across Pakistan. Had it not been for CPEC, the name Gawadar may not have found even a mention in the mainstream political discourse much less in electronic media. The country still does not have a maritime vision while the subject is all together missing from the manifestos of every major political party. Terms like CPEC, Gawadar, Arabian Sea, maritime security etc have frequently appeared in the print media over the past one year or so. Even then, a great percentage of public office holders would surely be found less than familiar with what sea or maritime commerce means for Pakistan.

Despite being a current issue of discussion in most world capitals, the geopolitical trends in the Asia-Pacific find only a fleeting reference in the syllabus of CSS (IR contemporary issues). There is no gainsaying that the region of Asia-Pacific has, and continues to fuel economic growth in larger Asia. It has precipitated a shift in the global economic centre of gravity from Atlantic to this region. The critical need to protect sea lines of communication and scamper to grab sea based resources through claims and counter claims over wider sea expanse has concurrently given rise to friction. It has drawn in more naval and maritime forces than at any other time in contemporary history. The US, China, India, Australia and Pakistan are all understandably concentrating their naval power and focusing strategies in the region.

A new era of geo-politics, cooperation and contest is underway in the region. This is manifest in flexing of naval muscle, expanding alliances and establishing a toehold in the Indian Ocean Islands in furtherance of strategic maritime interests. An ever expanding network of joint USN-IN operations in Indo-Pacific, operational integration of Arihant, Indias first nuclear submarine with Indian navy, establishment of first overseas military base by India in the Island of Seychelles, a New Delhis first tri-services command in Andaman-Nicobar Island are only some of the striking developments. These will have a definitive and cumulative impact in shaping the regions maritime security environment and larger world in future.

On November 14, the first Chinese cargo ship docked at Gawadar. A day earlier, the prime minister, accompanied by chief of the army staff and chief of the naval staff inaugurated the port of Gawadar. The inauguration marked the operationalisation and opening of commercial activities at the port. As CPEC matures, the national maritime security will increasingly define the economic fate of Pakistan. The success of CPEC will hinge on a fully functional port of Gawadar, the hub of all commercial activity. It will as much depend on safety and security provided to the maritime commerce of China, Pakistan and other countries travelling through sea lines of the Indian Ocean. Needless to mention, CPEC will add up to the predominant part of Pakistans trade already shipped through the sea.

The unraveling geo-politics and maritime security, the impact of maritime sector on Pakistans national economy as well as significance of Gawadar-CPEC are all too important issues to be ignored in any major prospective national decision making process. Yet like several other countries, Pakistan remains mired in what is termed as, sea blindness- also maritime blindness. It refers to a state where large segments of population are ignorant or unmindful of oceans and attendant matters. For reasons some of which are cited here, most of Asia is turning towards sea.

Both India and United States view CPEC as inimical to their strategic interests in the region. Wary of Chinas presence in the Indian Ocean, the US and India have already reached a momentous accord, the Logistic Sharing Agreement (LSA) which virtually amounts to war pact. The agreement will provide ease of operations and improve sustainability of the US navy. With CPEC advancing, China is also tipped to become a two ocean navy. It has already set a foothold in the Arabian Sea.

Adding to such developments is the change of guard in Washington. The newly elected US President Trump has already declared that Hindus and India will be Americas best friends. Just what the duo of two extreme right wing leaders in Trump-Modi could do to undermine Pakistans interests and security cannot be over-emphasised. Indias far-right ultra-nationalist Hindu Sena outfit is jubilant over the success of Mr. Trump. An emboldened government in New Delhi is meanwhile aggressively shifting to war mode with Pakistan.

Over the past two decades and as part of its corporate responsibility, Pakistan Navy has made concerted efforts to expand its national outreach. This has included consequential initiatives like moving Pakistan Navy War College from Karachi to Lahore, holding large-scale multinational naval exercises, increased interaction with academia, especially in Punjab, instituting joint seminars in collaboration with public sector universities etc. A revised National Maritime Policy and Strategy is understood to have been finalized by the Naval Headquarters/Ministry of Defence. The first Maritime Doctrine of Pakistan is also anticipated to be published in due course. The doctrine will provide an overarching view of Pakistans maritime sector, maritime security and peace/war time roles expected of Pakistan Navy.

Given the progressing developments and its importance for Pakistan, the present and future public office bearers owe a responsibility to the nation. They must ensure that maritime domain does not escape their attention. Its inclusion in the CSS examination syllabus and institution of appropriate module in the training at the civil services academy is an indispensable and urgent national need. It is time to adopt novel approach and inject new thinking in our national psyche that has for long remained land centric. It can gain considerable momentum if juvenile brains are prepared in time for what is going to be the real battle ground in twenty first century-the Indo-Pacific region. The verse of national poet Iqbal resonates fittingly:

Calvin Love staves off society’s imminent collapse with Warm Blindness & A Cool Breeze listen – Consequence of Sound (blog)

Wednesday, February 15th, 2017

The horses of the apocalypse have been galloping in for some time now, and far be it from us to claim that a singer-songwriter from Edmonton has any chance of keeping them at bay. But to listen to Calvin Loves new single Warm Blindness & A Cool Breeze is to accept that maybe everything isnt totally fucked after all. Love has made a name for himself with a series of lush, buoyant pop compositions that temper their sweetness with a bit of bite, and his latest is no different. It does happen to come at a time when we need it most, though, hitting us with a hopeful swell of guitars and a bass line that makes our booties shake for thank god some reason other than fear.

Warm Blindness & A Cool Breeze was written by accident and impulse, the songwriter tells Consequence of Sound. [Its] a metaphor for being lost in a cognitive dissonance while under the pressure of societies imminent apocalypse. Thats not a difficult sentiment to relate to these days, but Love maintains a positive perspective until the bitter end. Just as long as youre here with me/ Everything will be alright, he sings in the coda, and theres nothing really bitter about that at all, is there?

Warm Blindess & A Cool Breeze is off Loves upcomingEcdysis EP, due out April 7th via Modern Sky. Find the info below.

Harvard Tests A Brain Implant That Could Reverse Blindness – The Nerd Stash (press release)

Monday, February 13th, 2017

Technology is amazing. Within the last couple years alone, it has allowed human beings to advance in ways that, at one time, was only thought possible in science fiction. Virtual reality is becoming a household thing and 3D printing is changing lives. Now, technology is being tested to change a persons life entirely. In an upcoming study, Harvard Medical School is developing a brain implant that may reverse the effects of blindness long term.

Sometime next month, Harvard will begin testing the implant on primates. Instead of protruding into the brain, the new implant will rest right underneath the skull and sit on the brains surface. Tiny coils on the underside of the implantwill generate magnetic fields to initiate activity in different parts of the brain. Obviously, in this particular experiment, the researchers are focused on the effects this will have on thevisual cortex of the brain. They are hoping the surge of electricity from the implant will re-create the actions that causevision. In the end, the Harvard researchers are hoping to be able to turn signals from a camera into brain activity. If successful, the primates will be able to navigate a maze just by perceiving light, dark, and shapes. They will also be testing an implant that is embedded in the brain. Below, is a video that shows a brain implant giving a paralyzed monkey the ability to walk!

Unfortunately, this is an experiment that will not be finished anytime soon. The three-year project is being funded by a movement, the BRAIN initiative, put into action by President Obama. The initiative was put in place strictly for scientists to experiment in an attempt to better understand the human brain. When it comes to these sort of implants. they usually fail. The electrodes the implants are trying to pass through the various parts of the brain stop working when scar tissue builds around the implant. Since this new type of implant rests on top of the brain, scar tissue wont build up and erode these connections.

This implant could, not only, fix blindness in the long term, but could also be extremely useful for other sorts of disabilities.

How my husband saw blindness as a ‘dark, paradoxical gift’ – The Guardian

Sunday, February 12th, 2017

Marilyn Hull Like any bereavement, you get the anger and loss. The change in your life is so immense. Photograph: Dave Evitts/Guardian

Two wildly disparate films could be said to frame Marilyn Hulls life with her husband, John. Theres the extraordinary documentary Notes on Blindness, an intimate, highly inventive rendition of Johns experience of losing all vision in his 40s. And then there is the romantic epic Gone with the Wind, which they saw on their first date in 1975.

John Hull, a professor of theology, writer and campaigner, had been Marilyns university tutor when she was training to be a teacher in Birmingham. They lost touch but met again through his Amnesty branch and he asked her if shed like to see a movie. Recalling that trip to the cinema, Marilyn has to suppress rising tears. He had been a brilliant teacher, funny, warm, supportive, inspiring, she says. But he was married with a child, and I was not the type to fall for married men 17 years older than me. But I sensed an enormous vulnerability and a sadness in him. We got out of my car, he took my arm and I realised then that he fancied me. I was surprised at myself and my feelings. I dont know exactly what I felt, but I fell in love between the car park and the cinema door, and that never changed. Itwas cataclysmic.

Marilyn and John, who had a daughter from his first marriage, went on to have four children together. Both were passionately opposed to nuclear proliferation while John was also a key intellectual figure in theological education and the development of multi-faith thinking. He was a campaigner for social justice, right up until his death from pneumonia in July 2015.

For Marilyn, who had only recently retired as a headteacher, his death was devastating and she is still in mourning. She chokes up at odd moments in the supermarket realising that the cheese footballs he alone loved eating no longer need to go in the shopping-basket. She finds it almost impossible to watch Notes on Blindness, completed after his death, without crying.

The film, which has been nominated for three Baftas, draws on Johns audio diary from the first years of his total blindness. There were 16 hours of recordings, published as Touching the Rock in 1990. Oliver Sacks described it as The most extraordinary, precise, deep and beautiful account of blindness I have ever read. Its a book that not only gives a sighted reader vivid insights into the experience of becoming totally blind and learning how to navigate the world anew through sound, memory and touch, but also describes Johns psychological and spiritual struggle to accept what had happened to him.

The filmmakers lip-synched the recordings of Marilyn and Johns voices with two actors playing the couple during the years when John was struggling to come to terms with blindness. It has been exhilarating but emotionally exhausting for her to hear Johns voice throughout the film. I loved seeing the film in French. It was dubbed and it enabled me to get some distance on it.

When the couple met, John had already lost his sight in one eye because of a botched cataract treatment in his childhood in the Australian outback. He had never let his limited vision get in the way of his life and career but when his other eye failed and he became totally blind, it was devastating.

Like any bereavement, you get the anger and loss. The change in your life is so immense, says Marilyn.

In 1980, just days before the birth of their first child, Tom, the couple were told that Johns sight could not be saved. Marilyn remembers John being brought in his pyjamas from the eye hospital to visit her in the maternity ward. Friends and families didnt know whether to congratulate us or commiserate. We had a new baby, and had to work out brailling, white canes, all of that at the same time. That was seared for ever, that strange congruence in life.

Initially, John refused help simply because he was too busy with his work to go on courses. We lived at such a pace. And he couldnt have a dog because he had asthma. But he was so inventive and such a loving, attentive father he would tie a string around his foot and attach it to a crawling baby so he knew where they were. He was terribly independent. He would go out dragging the pushchair behind him to get somewhere and I would think, Oh my God, I hope they both come back safely!

She remembers terrible periods when he distanced himself completely. Not being able to see the children was very painful for him. I was so aware that anyone walking into our house could know our children in ways that John would never know them.

She would suggest that he go to his office and work in familiar and quiet surroundings, and come back when he had centred himself again. Life with John was mainly very joyful, but there were despairing, difficult times when I would wonder whether his blindness would fundamentally change our relationship.

During the early years of his blindness, John struggled to reconcile his dreams richly full of vivid images and his waking life in total darkness. In the book and the film, he describes how deeply troubling it was to accept that his visual memories were slipping away and how he felt it vital to live in a new reality rather than dwell in nostalgia. Eventually, he came to see blindness as a dark, paradoxical gift something people ask Marilyn to explain.

They say, Wouldnt you have loved him to have got his sight back? Of course, of course I would. But the gift is living with what is, rather than dwelling with some other imagined existence. He felt the miracle was renewed consciousness, the idea that you can live with integrity and clarity in what has become in many ways a very different world.

The film reconstructs the nightmarish time when they went to Australia with their young children to stay with Johns parents. Being in his childhood landscape with his mother and father but unable to see them was traumatising. It was the turning point when he was triggered into that new consciousness, when he decided, Right, I am not going to live in the world of images. I am going to live in a world where the whole category of appearance is meaningless to me. That photograph which I thought I would have forever in my heart, I have to forget. And if you love someone you have to say, Yes, of course I understand and respect that; you must go into that other world where I cannot follow. It was so hard not being able to alleviate the suffering, that he had to work through it all on his own.

The couple got back on the plane and just said to each other, We will never be able to go back. The time in Australia had not only tormented him psychologically but also worsened his chronic lung condition.

John was determined to be as independent as possible. He wrote: The moment I sink into passivity, I am done for. He had a relentless desire to get the most out of life but you cant multi-task and rush when you are blind and Marilyn, naturally impatient, realised that she too needed to adjust.

Sometimes with John youd think hed want you to back off; other times youd realise he was irritated because no one had told him the difference between the trifle and the cheese souffle. Not only was he a brilliant teacher at work, but he was also a brilliant teacher for sighted people, so people were comfortable in his presence.

She recalls her own anger though when strangers stared at him. At first Id be so irritated by them. I dont mind children staring, they dont know any better, but youd go into a restaurant and people would stare and stare. Id just stare back. Often people would talk to her in front of him as if he wasnt able to hear and she giggles remembering the time she waited silently beside him at a railway station ticket office until the seller finally asked John directly what he required.

When James Spinney and Peter Middleton first approached the couple in 2010 about making a film based on Johns audiotapes, they were intrigued. Its so counterintuitive, a film about blindness. John was not an attention-seeker but he was an extremely gifted public speaker. And James and Peter were so respectful and were the same age as our children and were so carefulto get it right emotionally. They kept checking with us. By the end youfelt they knew our lives better than we did.

Spinney recalls. Wed travel every few months to record interviews with them, revisiting the audio-cassette recordings that they kept in the years after John became blind. We were conscious that at times this was a painful undertaking. John likened it to reopening an old wound that had long since healed. They approached this with such honesty and generosity, which made the making of the film a very collaborative process. And over time it developed into a friendship, one that we feel very lucky to have had.

Marilyn feels that John would have been intrigued by the finished film and appreciated the innovative versions with enhanced audio descriptions for people with sight loss and the virtual reality companion piece.

But would he want Notes on Blindness to be his sole legacy? No, he was always interested in influencing the churchs political attitude, in his students development and protesting about Trident. Never was there a person who so fitted Dylan Thomas valediction: Do not go gentle into that good night. He was tweeting so ferociously in his final months, it seemed that the political pressures of the world were coming at him like fireworks, he was somebody who with their last breath was saying, What more can we do in this world?

It is less than two years since Johns death, and Marilyn still instinctively reaches her hand across the bed when she wakes. When she took his ashes to Australia, she found a photograph from their early days as a couple. Id never seen it before. I thought, this is the most important photograph of my life and I didnt know it existed. Its rare to get photos of people looking at each other intensely, staring into each others eyes, deeply in love. Its an intimate moment and theres usually nobody there to take it. Its just a tiny snap and I cannot publish it anywhere. Its that moment of beholding that we both lost.

Notes on Blindness will be on BBC4 on 16 February, 9pm. Notes on Blindness: A journey through the dark is published by Profile, 8.99. The VR companion film is free to get

80% of the world’s blindness is preventable. This hardware is fighting it in 26 countries – The Express Tribune

Sunday, February 12th, 2017

KC never set out to build a healthcare startup. An avid reader and cricket fan, K. Chandrasekhar known to colleagues as KC was working in the semiconductor industry years ago when he visited a hospital and discovered how big a problem preventable blindness was: around the world, 80 percent of blindness is preventable.

Blindness takes a toll on families too, he explains. The affected individuals responsibilities may include earning for the household, taking care of elderly parents, and looking after children.

This Pakistani startup is helping increase worker incomes by 400%

KC, an IIM-Calcutta alum, says the number of eye doctors in India now is closer to 20,000, but they still cant cater to everyone who needs eye care. Thats where he thinks technology can help, especially when a majority of blindness cases in the country 75 percent, or over 11 million in 2007 are preventable if causes like cataracts or glaucoma are caught early.

A Solution

In 2009, KC and Shyam Vasudev began work on healthtech hardware startup Forus Health. The Bangalore-based company has four products that range from US$4,000 to US$50,000. The 3Nethra classic is a small, portable digital imaging device. Itll take, store, and transmit pictures of the front and back of the human eye that help carry out a routine eye exam. It can detect problems like cataracts, glaucoma, diabetic retinas, problems with the cornea, and refractive errors all contributors to blindness that can be treated if caught early. Unlike other eye exams, the 3Nethra classic does not require pupil dilatation.

PHOTO: FORUS HEALTH

The 3Nethra Flora is a non-contact eye scanner that works with pupil dilation. It takes more in-depth pictures, including the layout of blood and lymph vessels in the eye.

Detection of eye issues in children, especially younger children who cant always communicate whether a lens prescription is correct, can be difficult. For younger or non-cooperative patients, Forus Health has the 3Nethra Kiddo, which helps detect refractive errors in eye patients. Refractive errors like nearsightedness or farsightedness occur when the eye is misshapen, causing light to bend differently around the eye. The 3Nethra Neo takes pictures of infant retinas to help diagnose and monitor diseases and disorders.

Forus Healths devices have been installed in nearly 1,400 places in 26 countries, including the US and countries in Europe and Asia. In April 2012, the startup raised US$5 million in series A funding from Accel Partners and IDG Ventures. Two years later, it bagged US$8.2 million in series B funding from Asian Health Fund, Accel Partners, and IDG Ventures.

Tackling Prevention

KC and his team now 125 people faced several of the problems other medical hardware makers come across. The product needs to be effective and cost-efficient enough to convince doctors, but also must appeal to the average patient, who doesnt have enough time to take off work unless theres something already wrong. Convincing those patients of the value-add of preventative care like eye screenings can be difficult..

PHOTO: FORUS HEALTH

The hardest thing is actually making people have a behavioral change, he tells Tech in Asia.

This Pakistani startup is revolutionising the way people travel

The argument for preventative care is simple spend a little time and money examining and monitoring your health now, and youre likely to catch problems early. Treatment for problems caught early will cost much less. Thats why Forus Healths flagship product the 3Nethra Classic doesnt require pupil dilation. The test can be done in five minutes, and the person can go straight back to work instead of waiting hours for his or her pupils to return to normal size.

It also needs to be user-friendly a lot of medical equipment is bulky and made for use in a hospital, but for the technology to work outside of cities, it has to be small, portable, and cost-efficient.

It took the company around 18 months to develop its first products; it would be three years before the team reached a satisfactory model.

Other startups working with low-cost healthcare hardware include Stasis Labs, Medaino, andTen3T.

Now, the startups focus is on expansion into other countries, something that KC mentions has always been their goal: if preventable blindness is a worldwide problem, the same goes for the companys focus.

Denzel Washington baffled by BAFTA blindness – RTE.ie

Sunday, February 12th, 2017

Updated / Saturday, 11 Feb 2017 14:25

Denzel Washington said he has "no idea"why he has never been nominated for a BAFTAAward. The Hollywood star has won two acting Oscars during his decades-long career and is nominated this year for another two: best actor and best picture for Fences, which he both directed and stars in. On his lack of a nod from the British Academy of the Film and Television Arts, he told the Press Association: "I've never been nominated for a Bafta. "You'll have to ask them why, I have no idea. I've been nominated for eight Oscars, won two." He added: "Morgan Freeman and I have never been nominated for a BAFTA." Washington's Fences co-star Viola Davis has received a nod in the best supporting actress category at this year's BAFTAs, which take place on Sunday February 12 at London's Royal Albert Hall. The actor, 62, also discussed the current trend for stars using their acceptance speeches at awards ceremonies to air their views about politics. He said: "It's America. People have the right to do and say what they want. There's a feeling in the air."

The dangers of snow blindness | WWLP.com – wwlp.com

Sunday, February 12th, 2017

SPRINGFIELD, Mass. (WWLP) After the snowstorm Thursday it was a nice winters day, with the sun shining down on the new white snow, but the reflection of the sunshine off the fresh snow could lead to problems with your vision.

One thing is snow blindness which is ultraviolet damage from reflections off the bright snow. Were relatively closer to sea level so its not as common here as if youre at altitude people who are mountaineering will get this a lot more, said Dr. James Rosenthal an ophthalmologist in Springfield.

Snow blindness occurs as a result of a burn to the clear front surface of the eye known as the cornea. Symptoms can include pain, redness, hazy vision and even a temporary loss of vision.

You can treat it with lubrication and in a mild case you can just go to the drug store get artificial tear preparation in a more severe case a patient may need to be patched with topical ointments.

The term used to describe the amount of sunlight reflected by snow is known as albedo. The albedo will be higher for new fresh white snow and it will be lower for older dirty snow.

The albedo of snow drops quickly after a storm due to sand and salt from the roads and pollutants in the air.

To protect yourself from snow blindness you should wear sunglasses or a hat with a brim.

Losing sight can make a patient feel broken and no longer whole, Rosemary Robinson explains

10 Feb 2017 by Selina Powell

Optometrists were cautioned against letting their own attitudes towards blindness get in the way of patient care during a 100% Optical presentation on vision loss and psychology.

Consultant ophthalmologist, Rosemary Robinson, emphasised that optometrists and ophthalmologists often viewed blindness as the ultimate professional failure.

Optical professionals react to loss of vision as other health professionals do to loss of life, Ms Robinson highlighted at the show (4-6 February, London ExCeL).

This sense of guilt was strongest in relation to vision loss from potentially curable conditions, she added.

However, optical professionals should not lose sight of the individual while treating a disease, Ms Robinson emphasised.

You are not responsible for vision loss but you are responsible for a patients overall care and treatmentEven if you cant make someone see better you can help make their quality of life better.

During her presentation, The Psychosocial Impact of Vision Loss, Ms Robinson detailed the different ways that blindness could affect a patient.

Some people who experienced vision loss felt broken and no longer whole, she explained.

Many people have a negative stereotype of a blind person and they self-impose that idea. They see themselves as an outsider and different from the rest of the community, she highlighted.

This effect on a persons self-esteem resulted in a patient reassessing their identity.

When blindness occurs its like theyve lost the previous person they were and they have to come to terms with who the new person with the sight loss is going to become, Ms Robinson explained.

Patients were often wary about how their vision would change in the future following a diagnosis.

When losing vision there is often the fear that they will go in to total darkness when, in fact, rarely this is the case, Ms Robinson added.

Losing the ability to see familiar faces and sights that bring people pleasure was a significant loss, she told delegates at the show.

Although a scene or object could be described to someone with sight loss, it was not the same, Ms Robinson explained.

It can be very different seeing it in your minds eye and it can be a source of frustration, she highlighted.

Ms Robinson detailed the different phases of coming to terms with sight loss, including trauma, shock and denial, mourning and withdrawal, and succumbing and depression.

The final stage was reassessment and reaffirmation, she added.

In this stage a patient began to view themselves as essentially the same as before their sight loss.

They just have to deal with life a little differently, Ms Robinson concluded.

Eye-med maker Allergan takes on preventable blindness with … – FiercePharma

Wednesday, February 8th, 2017

Late last year, a report urged health leaders to take action toward ending preventable blindness. And now, Allergan is leading a charge.

Tuesday, the Dublin drugmaker rolled out See America, an effort to increase awareness of the diseases that can cause preventable vision loss and to improve access to vision care.

Partnering with volunteer eye health and safety organization Prevent Blindness, Allerganwhich markets the glaucoma-fighting treatments Lumigan and Alphaganwill sponsor a series of vision-screening events in various cities. Attendees will receive free one-on-one professional eye exams, follow-up treatment plans and info about the most common vision-affecting diseases.

The new efforts from Allergan, which markets products for vision-damaging diseases including glaucoma, follow a September report from the National Academies of Sciences, Engineering, and Medicine that projected a doubling of preventable blindness and visual impairment by 2050 without a nationwide intervention.

With an unrivaled eye care portfolio, a national network of medical experts and an unwavering commitment to the future of America's eyesight, Allergan is standing at the forefront to answer NASEM's call, the company said in a statement.

Allergan isnt stopping there, though. Its joining up with celebrities and influencerswho it isnt yet at liberty to nameas well as renownedmedical experts who share our passion of preserving America's vision, an Allergan spokesperson said in an email interview. And because the company wants to reach people across the country, its looking to engage with them in the places they get their content dailysocial media, online, in magazines, newspapers etc.

More partnerships with like-minded organizations that support the goals of See America could be on the way, too. See America is a first step launched with hope that other industry leaders will join us in making eye health a priority, the spokesperson said.

See America isnt Allergans only recent eyecare marketing push. Last year, summer, the company recruited actress Marisa Tomei as a brand ambassador for Restasis, which is up against new dry eye competition in the form of Shires Xiidra.

Mobile clinic to help reduce blindness in Vanuatu – Radio New Zealand

Wednesday, February 8th, 2017

People on some of Vanuatu's most remote islands will be undergoing eye surgery following the installation of a clinic on a medical vessel.

Rotary clubs have raised thousands of dollars for optical equipment for the MV Pacific Hope, which has already been providing dental surgery in the Pacific.

The founder of New Zealand based faith charity Marine Reach David Cowie said the ship will sail out of New Zealand in April and head to Vanuatu.

He said they will be treating people like a 10-year-old child he met on a recent visit.

"I promised this little boy that I'd come back one day and take care of his blind eye, the cataract, really cute kid. Teacher said he was bright but was struggling because of his eyesight. So he represents dozens of children as well as adults throughout the islands that really desperately need help"

Three technologies improving quality of life for those with low vision, blindness – Bel Marra Health

Wednesday, February 8th, 2017

Home Eye Health Three technologies improving quality of life for those with low vision, blindness

February is National Low Vision Awareness Month, and the National Eye Institute is outlining five new technologies currently in development to make life for those with low vision or blindness easier.

Low vision is characterized by difficulty performing daily tasks even after receiving treatment in the form of glasses or contacts, medications, or surgery. The type of vision loss can vary based on the cause and can affect different aspects of an individuals life.

For example, the loss of peripheral vision may be due to glaucoma and can impact your ability to walk and drive, while central vision loss can occur because of age-related macular degeneration and make tasks like reading difficult. To help those living with low vision and blindness, researchers are currently developing technologies that can be used to make some of these tasks easier. Continue reading to learn more about these new innovations.

Co-Robotic Cane: A co-robotic cane is currently being developed by Dr. Chang Ye of the University of Arkansas, Little Rock to aid those with low vision in maneuvering indoors. There is existing GPS-based technology available to help people find a location, such as a building, but it isnt useful for finding and navigating specific rooms within a structure. The cane functions by providing feedback about the users environment, using a 3D camera and a motorized roller tip to drive the cane forward for the user to follow. The cane also stores preloaded floor plans that can be accessed through voice recognition, though Ye hopes to have the cane capable of downloading a buildings floor plans through Wi-Fi upon entry.

Robotic Glove: Dr. Ye is also working on a robotic glove to help the user locate and use small objects and doorknobs. The fingerless glove uses a camera and speech recognition to identify an object, then guides the hands movements through tactile prompts. For example, the user could say the word mug, and the glove would stimulate the nerves in the hand in a distinct pattern to guide their hand towards the mug and help them pick it up correctly.

Low vision and blindness affect 4.1 million Americans, and these new technologies are just three of the many in the works to help them accomplished daily tasks safely. While these tools require further testing and development, they provide hope that tasks such as crossing the road, navigating a room, and opening a door will be able to be accomplished much quicker by those affected by low vision and blindness.

Bowling and blindness: White Cane Week kicks off in Regina – Globalnews.ca

Tuesday, February 7th, 2017

Visual impairment didnt stop the clatter of falling pins at Reginas Golden Mile Bowling Lanes Monday morning.

Members of the Canadian Council of the Blind (CCB) Regina chapter took on the citys media in five-pin bowling in a friendly competition to focus attention on blindness and visual impairment.

CCB spokesperson Russell Coubrough put together the 46th Annual Media Bowling Challenge to kick-off White Cane Week 2017, the national initiative that puts visual impairment into the spotlight.

This is our main event that we have, the Media Bowling Challenge to promote awareness, Coubrough said.

According to the Canadian National Institute for the Blind (CNIB), approximately half a million Canadians live with significant vision loss around 15,000 of them are in Saskatchewan. Those numbers are expected to increase as much as 30 per cent in the next decade due to an aging population.

Terry Parsons, partially blind and an avid bowler since 1972, participated in the challenge and said the public needs to be aware that while the visually impaired may do some things slower, they should be treated equally.

We do things a little differently than what you guys might do, but were still doing it and were getting the job done, he said.

Visually impaired bowler Darlene Smith also had a message. She often has to remind the public that her guide dog, Deidra, is for her use only and cant be pet on the street like most other dogs.

People get mad at you when you tell them to leave her alone, because they dont understand that shes working, Smith said.

In the friendly five-pin competition, the media managed to squeak by with a 135-115 victory.

White Cane Week runs from Feb 5 to Feb 11. Saskatchewan also has a team competing at the Canadian Vision Impaired Curling Championship in Ottawa.
