UVM study: AI can detect depression in a child’s speech

uvm.edu
  • AI-powered tools for detecting anxiety in children’s voices are being developed.
  • A special algorithm analyzes statistical features of kids’ audio recordings.
  • The study involved a special version of the Trier-Social Stress Task, where 71 children between 3 and 8 y-o were asked to improvise a three-minute story.
  • The algorithm was 80% accurate in diagnosing internalizing disorders, and it’s now being developed into a tool for clinical use.
  • This is important, as 1 in 5 children suffer from internalizing disorders which increase the risks of substance use and suicide in later life if untreated.

Tesla sued in wrongful death lawsuit that alleges Autopilot caused crash

techcrunch.com
  • The article analyzes the lawsuit filed against Tesla Company by the family of Walter Huang, who died when his Tesla Model X car hit a barrier on Highway 101 in Mountain View, California.
  • According to the lawsuit, Huang's death was caused by failures of the vehicle's autopilot system that did not work properly at the time of the accident.
  • In the face of the wrongful death claim, Tesla argued that Huang was not paying attention to the road and did not heed the warning signals issued by the vehicle's system before the accident occurred.
  • The lawsuit intends to ensure that all technical systems and equipment installed in vehicles must be safe and sufficiently tested before being used by people on the roads.

With a simple twist, a ‘magic’ material is now the big thing in physics

quantamagazine.org
  • MIT physicists discovered ‘warm’ superconductivity, among other exciting characteristics, in two joined layers of graphene.
  • The extraordinary results were produced by finding the ‘magical’ angle to twist one layer - exactly 1.1°.
  • In 2007 it was suggested that pressing two misaligned layers of graphene could produce interesting effects.
  • Over 10 years later the theory is now confirmed by a paper that virtually created a new, currently exploding field - ‘twistronics’.
  • It is a huge milestone for studying superconductivity.

Apple cracks down on apps that fight iPhone addiction

nytimes.com
  • Analysis by The New York Times and Sensor Tower (app-data firm) shows that Apple has been killing the businesses of screen-use tracking app developers.
  • Shortly after announcing its own tools for limiting screen-use, Apple started removing apps with similar functionalities from the App Store.
  • They gave only a short explanation and virtually no support, destroying the viability of businesses like Mobicip that’ve supported the App Store for years.
  • As a result, some app makers with thousands of paying customers had to shut down, and others are worried about their future.

Green material for refrigeration identified

  • Traditional and inefficient cooling systems might finally get an eco-friendly replacement.
  • Current refrigerators and air conditioners use up ⅕ of electricity globally and use toxic and flammable gases as coolants, which contributes to global warming.
  • Now scientists have found that if put under pressure, plastic crystals of neopentylglycol (NPG) are a good candidate for replacing traditionally used gases.
  • NPG is widely available and inexpensive to produce.
  • It might be the answer to solving long-standing issues with traditional cooling systems.
