This Paralyzed Man Tweeted Just by Thinking About it

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 Builds 'Earth-2' Supercomputer to Accurately Simulate Climate Change

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.

Scientists use Cyberpunk Albatrosses to Scan for Infrasound at Sea

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.

Do You Have 100 Terabytes of Free Storage? Download the Universe

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.”

New Studies Show no Harmful Effects to Humans From 5G

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.
