The first person with Neuralink’s computer-linked chip implanted in the surface of their brain showed off their “telekinetic” online chess-playing skills while discussing the “life-changing” procedure for the first time in a surprise livestream.

Noland Arbaugh, a 29-year-old with quadriplegia (or paralysis that affects the body from the neck down), volunteered to have the device implanted as part of Neuralink’s ongoing trial of the technology. Until now, his identity had remained a closely guarded secret.

Ai’s superreality: not fit for human consumption.

Is AI’s brilliance pushing beyond human comprehension?

The highest rung on the ladder is studied by analyzing the redshifts of distant galaxies. This technique can be used to measure distances across of billions of light-years, by contrast.

Redshift occurs because, as objects race away from us due to the expansion of the universe, the light they emit that takes billions of years to travel to us has its wavelength stretched by this expansion. That lengthening reddens the light and even causes it to move to infrared wavelengths sometimes. This is actually why the James Webb Space Telescope (JWST), which is highly sensitive to infrared light, is so adept and seeing galaxies in the early universe.

The cosmic distance ladder can help cosmologists measure the rate at which the universe is expanding, a value called the Hubble constant, named in honor of astronomer Edwin Hubble. This is because his observations of distant galaxies were key in overturning the idea that the universe exists in a steady state, neither growing nor shrinking.

THURSDAY, March 21, 2024 (HealthDay News) — A germ commonly found in the human mouth can travel to colon tumors and appears to speed their growth, new research shows.

The finding might lead to new insights into fighting colon cancer, which kills more than 52,000 Americans each year, according to the American Cancer Society.

Researchers at the Fred Hutchinson Cancer Center in Seattle looked at levels of a particular oral bacterium, Fusobacterium nucleatum, in colon tumor tissues taken from 200 colon cancer patients.

The big picture: Sand batteries might not be as efficient for generating electricity as they are for heating, but they could still have a huge impact on climate emissions — about 9% of the heat needed for buildings and industry comes from district heating systems, and 90% of those rely on fossil fuels.

We could then supplement the sand batteries with another alternative form of storage, such as flow batteries, to generate electricity from renewables year-round — completing the transition to a clean energy future.

GPT-5 on the horizon, as Altman drops hints.

A flat sheet of atoms can act as a kind of antenna that absorbs light and funnels its energy into carbon nanotubes, making them glow brightly. This advance could aid the development of tiny future light-emitting devices that will exploit quantum effects.

Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth.

The eight-atom body-centered cubic (BC8) crystal is a distinct carbon phase: not diamond, but very similar. BC8 is predicted to be a stronger material, exhibiting a 30% greater resistance to compression than diamond. It is believed to be found in the center of carbon-rich exoplanets. If BC8 could be recovered under ambient conditions, it could be classified as a super-diamond.

This crystalline high-pressure phase of carbon is theoretically predicted to be the most stable phase of carbon under pressures surpassing 10 million atmospheres.
