When the meteor that Avi Loeb, director of the Institute for Theory and Computation at Harvard University calls IM1 streaked across the sky on 8 January 2014, it was nothing special.

Yes, at half a meter in diameter, it was big enough to put on a nice show for people on the ground, ending in a rapid series of explosions high in the atmosphere.

“There were some reports of flashes in the sky, and there was probably a boom, although I’ve never heard anyone say that,” says Loeb’s colleague, Rob McCallum of Cambridge, Massachusetts.

The Columbus Dispatch, a newspaper serving the Columbus, Ohio area, has suspended its AI efforts after its AI-powered sports writing bot was caught churning out horrible, robotic articles about local sports, Axios reports.

The Dispatch — which is notably owned by USA Today publisher Gannett — only started publishing the AI-generated sports pieces on August 18, using the bot to drum up quick-hit stories about the winners and losers in regional high school football and soccer matches. And though the paper’s ethics disclosure states that all AI-spun content featured in its reporting “must be verified for accuracy and factuality before being used in reporting,” we’d be surprised if a single human eye was laid on these articles before publishing.

A biological pathway through which myelin, the protective coating on nerve fibers, can be repaired and regenerated has been discovered in a new study. The ramifications of this finding could be far-reaching for those with neurological diseases affecting myelin, many of which are currently untreatable.

If the axons that shoot out from the cell bodies of neurons are like electrical wires, you can think of the myelin sheath as the insulating plastic outer coating. In the brain, these sheathed nerve fibers make up most of the tissue known as white matter, but axons throughout the body are also coated in myelin.

The myelin sheath’s main functions are to protect the axon, to ensure electrical nerve impulses can travel quickly down it, and to maintain the strength of these impulses as they travel over what can be very long distances.

At a crucial time when the development and deployment of AI are rapidly evolving, experts are looking at ways we can use quantum computing to protect AI from its vulnerabilities.

Machine learning is a field of artificial intelligence where computer models become experts in various tasks by consuming large amounts of data, instead of a human explicitly programming their level of expertise. These algorithms do not need to be taught but rather learn from seeing examples, similar to how a child learns.

Researchers at the Hong Kong University of Science and Technology (HKUST) have found how stem cells’ surrounding environment controls them to differentiate into functional cells, a breakthrough critical for using stem cells to treat various human diseases in the future.

Stem cells play a crucial role in supporting normal development and maintaining tissue homeostasis in adults. Their unique ability to replicate and differentiate into specialized cells holds great promise in treating diseases like Parkinson’s disease, Alzheimer’s disease and type I diabetes by replacing damaged or diseased cells with healthy ones.

Despite their potential therapeutic benefits, one of the major challenges for cell therapies lies in efficiently differentiating stem cells into functional cells to replace damaged cells in degenerative tissue. This task is particularly difficult due to the limited understanding of the underlying molecular mechanism by which the tissues around stem cells, known as the stem cell niche, guide stem cell progeny to differentiate into proper functional cell types.
