NASA picked two winners for the Vascular Tissue Challenge, a $ 500,000 contest they announced in 2016, which brings us one step closer to printing artificial organs in space.
How is printing organs and tissues on Earth different from printing in space? Boland described the difference in techniques by comparing the mechanics of printing with Play-Doh to printing with honey.
China launched three astronauts into space on its first human-crewed mission in five years. Astronauts will spend around 90 days aboard Tiangong, China’s new modular space station currently under construction.
With this, the Chinese station, called Tiangong, or Celestial Palace, became one of two populated outposts in orbit. The other, the International Space Station, has been in operation for more than two decades, but its future is uncertain due to age, budget constraints and tensions between its major partners, the United States and Russia.
The age of disinformation
Georgetown researchers have found that AI is good enough for writing disinformation these days.
“With a little human curation, GPT-3 is quite effective” at promoting lies, says Ben Buchanan, a Georgetown professor involved in the study, which focuses on the intersection of AI, cybersecurity and security. the art of governing.
Georgetown researchers say GPT-3, or a similar AI language algorithm, could be particularly effective at automatically generating short messages on social media, what researchers call “one-to-many” disinformation. “.
⚛️ Quantum Mechanics
Researchers at the University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature. Normally, they should be cooled to -270 degrees Celsius (see document).
“We have developed a special coating for our memory chips that helps the quantum bits of light to be the same and stable while at room temperature. In addition, our new method allows us to store qubits much longer, i.e. milliseconds instead of microseconds, which was not possible before. We are really delighted, ”says Eugene Simon Polzik, professor of quantum optics at the Niels Bohr Institute.
Biden has appointed Columbia University law professor Lina Khan as federal trade commissioner, suggesting that the focus of US antitrust policy may shift from impact on consumers to a more European focus on the impact on competitors.
In a 2017 Yale Law Journal article, “Amazon’s Antitrust Paradox,” Ms. Khan argued that the “consumer welfare” standard is “not equipped to capture the architecture of market power in the market. modern economy ”. Amazon, she said, has increased its dominance by charging lower prices and expanding its business, thus undermining its competitors.
Amazon and other tech giants deserve antitrust scrutiny for some of their business practices, such as Amazon’s dominance in eBooks. But this dominance of the e-book was encouraged by an antitrust court case that undermined competition from Apple. Removing the consumer welfare standard would punish companies that cut prices and innovate.
🧱 Advanced materials
Researchers at the Australian National University (ANU) have developed new night vision technology that is extremely light, inexpensive and easy to mass produce (see article).
“Our technology is able to transform infrared light, normally invisible to the human eye, into images that people can clearly see, even from a distance.
“We made a very thin film, made up of nanoscale crystals, hundreds of times thinner than a human hair, which can be applied directly to eyeglasses and acts as a filter, allowing you to see into the eye. darkness of the night. “
