1. A chip made with carbon nanotubes, not silicon, marks a computing milestoneResearchers built a new kind of computer chip with thousands of carbon nanotube transistors. Though the prototype cant yet compete with silicon chips, carbon nanotube computing technology could lead to faster electronics (SN: 9/28/19, p. 7).

2. People can sense Earths magnetic field, brain waves suggestPeoples brain waves showed a distinct pattern when exposed to an Earth-strength magnetic field pointing in a specific direction in the lab. That finding hints that humans may have magnetoreception, similar to birds and certain other organisms .

3. In a first, scientists took the temperature of a sonic black holeThe temperature of a lab-made black hole that traps sound instead of light agrees with a prediction by cosmologist Stephen Hawking: that black holes emit a small stream of particles called Hawking radiation (SN: 6/22/19, p. 14).

4. Why kids may be at risk from vinyl floors and fire-resistant couchesChildren from homes with all vinyl flooring and flame-retardant couches had higher levels of some potentially harmful chemicals in blood and urine than other kids did, one study found.
