  • MIT researchers claim that deep learning neural networks need better uncertainty analysis to reduce errors.
  • "Deep evidential regression" reduces uncertainty after only one pass on a network, greatly reducing time and memory.
  • This could help mitigate problems in medical diagnoses, autonomous driving, and much more.

  • Students say they were identified with facial recognition technology after a protest at the University of Miami; campus police claim this isn't true.
  • Over 60 universities nationwide have banned facial recognition; a few colleges, such as USC, regularly use it.
  • Civil rights groups in Miami have called for the University of Miami to have talks on this topic.

Will America’s disregard for science be the end of its reign?

Confirmation bias is baked into the DNA of America, but it may soon be the nation's undoing.

  • From America's inception, there has always been a rebellious, anti-establishment mentality. That way of thinking has become more reckless now that the entire world is interconnected and there are added layers of verification (or repudiation) of facts.
  • As the great minds in this video can attest, there are systems and mechanisms in place to discern between opinion and truth. By making conscious efforts to undermine and ignore those systems at every turn (climate change, conspiracy theories, coronavirus, politics, etc.), America has compromised its position of power and effectively stunted its own growth.
  • A part of the problem, according to writer and radio host Kurt Andersen, is a new media infrastructure that allows for false opinions to persist and spread to others. Is it the beginning of the end of the American empire?

Paradox-free time travel is 'logically' possible, say physicists

Grandfathers, take heart. You'll survive the paradox that's been gunning for you since the 1930s.

  • For a century, the specter of paradoxes has loomed over physics theories and science fiction scripts.
  • A University of Queensland undergraduate and his supervisor ran the numbers and found paradox-free time travel to be mathematically consistent.
  • But the practical hurdles to time travel vastly out distance the mathematical ones.

  • Bioprinting soft human tissues has always been a challenge for bioprinters.
  • Techshot's 3D BioFabrication Facility utilized the microgravity of space to successfully manufacture human heart tissues.
  • While complete-organ manufacturing remains years away, the technology provides a promising step toward easing wait lists and personalized medicine.
