A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help…

In studying how neurotransmitters travel between cells -- by analysis of events in the dimensions of nanometers -- Cornell researchers have discovered that an electrical current thought to be present…

Researchers have made synthetic lipids called pseudoceramides that are involved in skin cell growth and could be used in treating skin diseases in which skin cells grow abnormally. Ceramides are…

In obese individuals, fat cells are bloated and inflamed because they receive too many nutrients, including lipids. In these cells, various components cannot work properly anymore and, instead, they…

Yes, last week science said Song Debunked: Breaking Up Actually Not So Hard To Do but it's a new week and this is a different study. They use the same song example, though. Dr. Bronwen…

Astronomers at the University of Rochester have discovered five Earth-oceans’ worth of water that has recently fallen into the planet-forming region around an extremely young, developing star. Dan…

Why do some people quickly link up with mates who love them good and strong, while others gravitate to people who hurt them, dump them or withhold love? It's all in the neurochemistry. I've come up…

Throughout Earth's history, 90,000 out of every 100,000 years have been ice ages - and it's been 12,000 years since the last one. You can thank global warming, it seems. Future ice ages may be…

In evolutionary terms, the difference between 2.1 and 2.2 children is a lot more important than the small difference sounds, especially as it accumulates over time. A new study in Royal Society…
