In a milestone achievement, a whole chromosome has been created from scratch by scientists for the first time ever.

The tRNA Neochromosome is a man-made chromosome of the common baker’s yeast Saccharomyces cerevisiae. It may soon allow for the creation of synthetic and superior yeast cells, according to a collection of new papers in the scientific journals Cell and Cell Genomics.

This discovery is the newest in an international project called Sc2.0, which has also synthesized all 16 of the yeast’s chromosomes with an aim to combine them into a functional cell that might help make yeast faster, more resilient and more productive.

On Monday, Nvidia announced the HGX H200 Tensor Core GPU, which utilizes the Hopper architecture to accelerate AI applications. It’s a follow-up of the H100 GPU, released last year and previously Nvidia’s most powerful AI GPU chip. If widely deployed, it could lead to far more powerful AI models—and faster response times for existing ones like ChatGPT—in the near future.

According to experts, lack of computing power (often called “compute”) has been a major bottleneck of AI progress this past year, hindering deployments of existing AI models and slowing the development of new ones. Shortages of powerful GPUs that accelerate AI models are largely to blame. One way to alleviate the compute bottleneck is to make more chips, but you can also make AI chips more powerful. That second approach may make the H200 an attractive product for cloud providers.

The Earth spins at different rates depending where you are on the globe. If it started to spin faster, you’d eventually be too dead to worry about it.

Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.

Deep-frozen corals, cryopreserved in the hope of restoring ocean ecosystems, are growing up. Could the futuristic technique eventually save dying reefs?

Although the transcriptomic signature of the tumor could not predict recurrence or the risk of progression, that of the TAN sample could successfully predict the recurrence of the disease and aid the stratification of patients into high-and low-risk groups.

This indicates the potential role of TAN tissue in future recurrence and its utility in predicting prognosis. However, TAN tissue could not accurately predict the formation of a new primary tumor.

Alaskans and visitors may be able to see an artificial airglow in the sky created by the High-frequency Active Auroral Research Program during a four-day research campaign that starts Saturday.

Scientists from the University of Alaska Fairbanks, Cornell University, University of Colorado Denver, University of Florida and Georgia Institute of Technology will conduct a variety of experiments at the UAF-operated research site.

The experiments will focus on the ionosphere, the region of the atmosphere between about 30 and 350 miles above the Earth’s surface.

The resolution of a major discrepancy between theory and experiment for strontium atomic clocks could help improve the precision of these timekeepers.

A fluid phenomenon seen daily in kitchens has been found to exhibit unexpected behavior.
