Meta announces Make-A-Video, which generates video from text
Posted by Dan Kummer in category: robotics/AI
Today, Meta announced Make-A-Video, an AI-powered video generator that can create novel video content from text or image prompts, similar to existing image synthesis tools like DALL-E and Stable Diffusion. It can also make variations of existing videos, though it’s not yet available for public use.
The key technology behind Make-A-Video—and why it has arrived sooner than some experts anticipated—is that it builds off existing work with text-to-image synthesis used with image generators like OpenAI’s DALL-E. In July, Meta announced its own text-to-image AI model called Make-A-Scene.

A man’s cancer vanished after he was injected with a weakened herpes virus in a promising clinical trial
Posted by Paul Battista in category: biotech/medical
A new cancer therapy that uses a modified herpes virus to attack tumor cells showed promise in early clinical trials abroad.
The drug, called RP2, completely obliterated one patient’s oral cancer. The 39-year-old told the BBC that he had cancer of the salivary glands, which continued to grow despite attempts at treatment.
He was preparing for the end of his life when he learned about the experimental drug, which was available through a phase one safety trial at the Institute of Cancer Research in the UK.

Princeton scientists overcome key setback in achieving nuclear fusion
Posted by Gemechu Taye in categories: physics, space
The researchers are one step closer to making the technology viable.
Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have taken a critical step forward toward achieving nuclear fusion.
The scientists traced back the collapse to the 3D disordering of strong magnetic fields.

Ancient stars that ‘tore themselves apart’ as they were dying have just been found, says new study
Posted by Gemechu Taye in categories: chemistry, space
The universe’s first stars, known as population III, could have had masses up to 250 times greater than that of the Sun. We may now have proof of them.
Astronomers now believe they have discovered ancient chemical remnants of the universe’s first stars, according to new research published in The Astrophysical Journal.
For decades scientists have been diligently looking for direct evidence of these ‘first generation’ stars believed to have formed when the Earth was a modest 100 million years old. The discovery could improve our understanding of how matter in the universe evolved into what it is today, including us. Commons.

It’s official: Dogs can sniff out stress on humans’ breath and sweat
Posted by Gemechu Taye in categories: biotech/medical, neuroscience
Dogs are amazing, and we all know it.
Dogs do a lot for us. They sniff out diseases, lead those who are blind or visually impaired, and search for humans in disaster areas. And it would come as no surprise if we told you that they could detect stress through humans’ sweat and breath, as well.
Researchers from Queen’s University, Belfast, collected sweat and breath samples of 36 participants before and after they handled a tense mental arithmetic task.

Our galaxy is rippling thanks to a mysterious force — we might finally know what it is
Posted by Gemechu Taye in category: space
An analysis of over 20 million stars shed new light on our galaxy’s cannibalistic past.
A nearby mini-galaxy, the Sagittarius dwarf galaxy, slowly crashed through the Milky Way and ripped stars out of their regular orbits on more than one occasion, according to a new paper in the Royal Astronomical Society.
Their analysis shed new light on the galaxy’s violent past — one in which galaxies tear into each other, shifting their structures for eons to come.

Netherlands researchers break the 30 percent barrier in solar cells
Posted by Gemechu Taye in categories: solar power, sustainability
Four terminal perovskite-silicon photovoltaic designs helped them in their cause.
A collaboration of researchers from various institutes in the Netherlands broke the 30 percent barrier associated with solar cells. The achievement will help uptakeworldwide solar energy and reduce our dependence on fossil fuels, an organizational press release said.
Even as governments across the world are promoting solar energy in their bid to reduce carbon emissions, the adoption of the technology has been limited by its energy conversion efficiency. Most commercially available solar panels top out at 22 percent energy conversion efficiency.

Drinking 2 to 3 cups of coffee per day could have a surprising effect on longevity
Posted by Gemechu Taye in categories: biotech/medical, chemistry, food, life extension
Including decaffeinated and instant ones.
A new study conducted by Australian scientists suggests that consuming two to three cups of decaffeinated, ground, and instant coffee can lower the risk of developing cardiovascular disease and dying early.
“In this large, observational study, ground, instant, and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular disease and death from cardiovascular disease or any cause,” says study author Professor Peter Kistler of the Baker Heart and Diabetes Research Institute in a media release.

NFT sales plummet 98% in eight months of this year
Posted by Gemechu Taye in category: blockchains
Are NFTs seeing a revival in different “avatars”, though?
The rage among celebrities last year, non-fungible tokens (NFTs), have been hit badly by the crypto winter and have seen sales dip by 98 percent in the eight months since January, Coin Telegraph.
How bad are trading volumes for NFTs?
