Recent research has shown that a drug known as MI-2 can kill cells that cause a fatal brain cancer. But only now have scientists been able to explain how the compound works: by targeting cholesterol production in tumors.
Studying a brain region involved in memory, researchers discovered a set of neurons that help mice control their appetite.
New research on leptin, a hormone that regulates appetite, reveals a previously unknown mechanism that may be responsible for at least 10 percent of obesity cases. The findings could help identify individuals with treatable forms of the condition.
When looking for food, the roundworm C. elegans searches the same area for up to 20 minutes before trying its luck at more distant locales. New research on the worm’s brain explains how this behavior arises at the level of molecules and cells.
Despite decades of study, we know surprisingly little about why neurons fail and memories fade. One researcher is finding clues where few others have looked—in the brain’s blood chemistry.
Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects’ impulse to feed on warm-blooded hosts.
