Now that we know that interstellar objects (ISOs) visit our solar system, scientists are keen to understand them better. How could they be captured? If they’re captured, what happens to them? How many of them might be in our solar system?

One team of researchers is trying to find answers.

We know of two ISOs for certain: “Oumuamua and comet2I/Borisov...

Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers at UZH and USZ have found. Their findings will now be tested in human clinical trials.

Serotonin is a neurotransmitter that is also known as the happiness hormone because of its beneficial effects on mood. In depressed people, the concentration of serotonin in the brain is reduced. The hormone also influences many other functions throughout the body...

When you shrink down to very small scales, heat doesn’t always behave the way you think it should. Now, new findings from the nano realm could help researchers to gain a better handle on the flow of heat in electronic devices.

A team of physicists at CU Boulder has solved the mystery behind a perplexing phenomenon in the nano realm: why some ultra-small heat sources cool down faster if you pack them closer together. The findings, published today in the journal Proceedings of the National Academy of Sciences (PNAS), could one day help the tech industry design faster electronic devices that overheat less.

“Often, heat is a challenging consideration in designing electronics...

Like the speed of an advancing race car driver, the winds in the outermost “lane” of Jupiter’s Great Red Spot are accelerating – a discovery only made possible by NASA’s Hubble Space Telescope, which has monitored the planet for more than a decade.

Researchers analyzing Hubble’s regular “storm reports” found that the average wind speed just within the boundaries of the storm, known as a high-speed ring, has increased by up to 8 percent from 2009 to 2020. In contrast, the winds near the red spot’s innermost region are moving significantly more slowly, like someone cruising lazily on a sunny Sunday afternoon.

The massive storm’s crimson-colored clouds spin counterclockwise at speeds that exceed 400 miles per hour – and the vortex is bigger than Earth itself...
