Researchers from the Gwangju Institute of Science and Technology in South Korea developed a silk-based physical unclonable function (PUF).
A 62-year-old Australian man who was paralyzed recently sent out a tweet “using only direct thought.”
The ‘first direct-thought tweet’ was created wirelessly from O’Keefe’s brain, according to the company. Following progressive paralysis caused by ALS, the man had a brain computer interface called ‘Stentrode’ installed last year. The implant, “designed to enable patients to wirelessly control digital devices through thought,” was inserted via the jugular vein to avoid drilling into the skull.
Nvidia is building a powerful supercomputer it calls Earth-2. They want to use simulation to make predictions in climate change with meter-scale resolution.
For the first time, we have the technology to do ultra-high-resolution climate modeling, to jump to lightspeed and predict changes in regional extreme weather decades out.
We can achieve million-x speedups by combining three technologies: GPU-accelerated computing; deep learning and breakthroughs in physics-informed neural networks; and AI supercomputers, along with vast quantities of observed and model data to learn from.
Wired is out with a cool story on Monday. Scientists fit albatrosses with sensor-laded backpacks to scan for infrasound.
Their wingspans, which can be 11 feet long, are lengthier than any human is tall. This allows them to spend considerable time simply floating on air currents above open waters, something that conserves energy as they embark on foraging trips. Not only do they fly across vast swaths of isolated ocean, but they don’t dive into the water, so any sensors attached to them wouldn’t get especially wet.
Researchers have prepared the Uchuu simulation of the universe, the most detailed ever made so far. It contains 2.1 trillion “particles” in a space 9.6 billion light-years across.
The simulation models the evolution of the universe across more than 13 billion years. It doesn’t focus on the formation of stars and planets but instead looks at the behavior of dark matter within an expanding universe. The detail of Uchuu is high enough that the team can identify everything from galaxy clusters to the dark matter halos of individual galaxies. Since dark matter makes up most of the matter in the universe, it is the main driver of galaxy formation and clustering.
“Fortunately, if you don’t have that much spare change, you can access the data online. The Uchuu team has their raw data on skiesanduniverses.org, so you can explore their virtual universe all you want.”
Two companies have gotten funding from Apple’s Racial Equity and Justice Initiative, a biotech startup called SweetBio and a venture capital firm called VamosVentures.
Based on the biggest wildlife camera trap study ever, Unseen Empire takes you through the research process.
In playing the game, users can re-enact the research process as they place camera traps across eight countries and collected and identify hundreds of never-before-seen photos of rare animal species.
Researchers helped a paralyzed person to write just by imagining that we was writing, by using a neural implant.
Researchers from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and the Swinburne University of Technology in Australia analyzed studies that find no evidence of 5G harming humans.
Aside from looking at animal and lab experiments, one review also analyzed epidemiological studies of radar, which uses the same sort of RF (low-level energy fields above 6 gigahertz to as high as 300 GHz) that 5G is expected to rely on. Their conclusions, based on reviewing data from over 100 studies, should be reassuring.
The Apple Women’s Health Study team at Harvard T.H. Chan School of Public Health released preliminary results on Tuesday.
