A popular and easy method for validating whether or not a chunk of rock is a meteorite, and what kind of meteorite it is, has been inadvertently erasing invaluable information locked inside.

The use of rare-earth magnets such as neodymium erases and overwrites the magnetic record locked inside ferromagnetic minerals in meteorites, scientists from MIT in the US and Paris Cité University in France found. Since many meteorites that fall to Earth have a significant iron content, this means we’re losing important data on the way magnetic fields in space have altered these meteorites over billions of years.

Meteorites provide invaluable records of planetary formation and evolution. Studies of their paleomagnetism have constrained accretion in the protoplanetary disk, the thermal evolution and differentiation of planetesimals, and the history of planetary dynamos.

Researchers at UC Davis are the first to report how a specific type of brain cells, known as oligodendrocyte-lineage cells, transfer cell material to neurons in the mouse brain. Their work provides evidence of a coordinated nuclear interaction between these cells and neurons. The study was published today in the Journal of Experimental Medicine.

“This novel concept of material transfer to neurons opens new possibilities for understanding brain maturation and finding treatments for neurological conditions, such as Alzheimer’s disease, cerebral palsy, Parkinson’s and Huntington’s disease,” said corresponding author Olga Chechneva is an assistant project scientist at UC Davis Department of Biochemistry and Molecular Medicine and independent principal investigator in the Institute for Pediatric Regenerative Medicine at Shriners Children’s Northern California.

Oligodendrocyte-lineage cells, also called oligodendroglia, are a type of glial cells found in the central nervous system. From birth onward, these glial cells arise to support neural circuit maturation. They are mostly known for their role in myelination—the formation of the insulating myelin sheath around nerve axons.

Chinese hackers could also attack the networks of companies that provide services to the military or to critical infrastructure operators, holding their systems hostage for ransom payments.

“If you get the right supply chain, it can have a lot of effects against a lot of targets,” said John Hultquist, head of Mandiant Intelligence Analysis at Google Cloud.

Summary: Two distinct networks in the frontal and temporal lobes become activated and work in unison to integrate the meaning of words in order to obtain a higher-order and more complex meaning when reading.

When a person reads a sentence, two distinct networks in the brain are activated, working together to integrate the meanings of the individual words to obtain more complex, higher-order meaning, according to a study at UTHealth Houston.

New research claims to have created an artificial pathologist.

There’s no denying that early detection of cancer improves the survival rate of a patient. Its diagnosis, which is carried out by detecting changes in the cell size, shape, or form, is pivotal to the pathology of the disease.

Now in most cases, doctors need to do a biopsy to be sure a patient has cancer. The analysis of solid tissue biopsies is commonly done in the middle of a medical operation by trained pathologists. This expert analysis requires pathologists to perform multi-step processes and inspect the tissues under a microscope, all while the patient lies on the operation table. This process, more often than not, takes a lot of time, resources, and labor.

World’s biggest search engine threatened by competition from Microsoft’s Bing.

Google is synonymous with the internet. Millions throng to the search engine every day. From catching up on what’s happening in the world to discovering how to dye your cat green, Google has the answer to everything.

So, it was only a matter of time before the tech giant integrated its widely used search engine with artificial intelligence. This was inevitable, with almost all major tech companies dashing to cash in on the expanding AI space. It has already launched an AI-powered chatbot called Bard, similar to ChatGPT.

A song featuring the voices of Drake and The Weeknd called “Heart On My Sleeve” has amassed over 250,000 Spotify streams and 10 million views on TikTok. But the two renowned musicians had nothing to do with the song — an artist going by the name “ghostwriter” generated the song using AI.

Drake and The Weeknd have not yet responded to the song, but Drake recently commented on AI-generated music that rips off his voice. When Drake noticed an AI model of himself singing “Munch” by Ice Spice, he wrote on his Instagram story, “This is the final straw AI.” It’s possible he was messing around, but he would be far from the first major artist to take issue with the rising count of deepfake songs.

In 2020, Jay-Z’s agency Roc Nation submitted copyright strikes against YouTube uploads of AI-generated Jay-Z deepfakes, but YouTube ended up reinstating the videos. And just last week, the same thing happened to Eminem; UMG, which represents both of these rappers, issued a copyright strike on AI-generated YouTube videos of Eminem rapping about cats.

Self-driving cars are taking longer to arrive on our roads than we thought they would. Auto industry experts and tech companies predicted they’d be here by 2020 and go mainstream by 2021. But it turns out that putting cars on the road without drivers is a far more complicated endeavor than initially envisioned, and we’re still inching very slowly towards a vision of autonomous individual transport.
