First model that is fully consistent with all FBOT observations. Ever since they were discovered in 2018, fast blue optical transients (FBOTs) have utterly surprised and completely confounded both observational and theoretical astrophysicists.

So hot that they glow blue, these mysterious objects are the brightest known optical phenomenon in the universe. But with only a few discovered so far, FBOTs’ origins have remained elusive.

Now a Northwestern University astrophysics team presents a bold new explanation for the origin of these curious anomalies. Using a new model, the astrophysicists believe FBOTs could result from the actively cooling cocoons that surround jets launched by dying stars...

Potential new therapeutic target for pancreatitis and pancreatic cancer. Now, Salk scientists report in the journal Gastroenterology on April 21, 2022, that a protein known as estrogen-related receptor gamma (ERR ɣ) is critical for preventing pancreatic auto-digestion in mice. Moreover, they discovered that people with pancreatitis have lower levels of ERR ɣ in cells affected by this inflammation.

These findings suggest that new therapies aimed at regulating ERR ɣ activity could help prevent or treat pancreatitis and pancreatic cancer.

“Our finding provides new insight into both the ...

New solar cell devices that are cheaper and easier to make could soon make their way to market thanks to materials made at Imperial College London.

Traditional solar cells are made from silicon, which has good efficiency and stability, but is relatively expensive to make and can only be manufactured in stiff panels.

Perovskite solar cells offer an intriguing alternative; they can be printed from inks, making them low cost, high efficiency, thin, lightweight and flexible. However, they have trailed behind silicon solar cells in efficiency and, importantly, stability, breaking down under normal environmental conditions.

New metal-containing materials called ferrocenes could help with these problems...

Planet’s atmosphere explains the gravity of the situation. If not for the soupy, fast-moving atmosphere on Venus, Earth’s sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth.

The gravity of a large object in space can keep a smaller object from spinning, a phenomenon called tidal locking. Because it prevents this locking, a UC Riverside scientist argues the atmosphere needs to be a more prominent factor in studies of Venus as well as other planets.

These argument...
