First material found to "remember" its own history (2 minute read)

Vanadium dioxide (VO2) is a material that is normally an insulator, but it changes structure and acts like a metal when heated to 68 degrees Celsius. It can conduct electricity without conducting heat. A team of scientists recently discovered that VO2 can 'remember' phase transitions for at least three hours. It is the only material known so far to behave this way. The discovery could lead to a new class of memory and data processing devices.

Twitter’s former security chief says company lied about bots and safety (4 minute read)

Twitter's former head of security has accused the company of negligent security practices.

About half of Twitter's 7,000 or so full-time employees have access to users' sensitive personal data and internal software.

The company could face significant fines if the accusations are proven to be correct.
