An experimental combination therapy triggered a 700% increase in insulin-producing pancreatic beta cells in laboratory mice . The drugs – a plant compound called harmine plus a common diabetes drug (GLP-1 receptor agonist like exenatide) – made leftover human beta cells multipl...
Researchers have identified a specific subspecies of oral bacteria that appears to fuel colorectal tumors. The culprit is Fusobacterium nucleatum, a germ from gum disease. This bacterium is rarely found in healthy guts, but is often present in colon cancers. A new study found that...
New animal research suggests that “overloading” on protein supplements can backfire. When mice were fed a diet with very high levels of the branched-chain amino acids (BCAAs) found in protein powders, they experienced negative effects on mood, appetite, and lifespan m. The study (in...
Scientists are finding that our gut bacteria could play a surprising role in sarcopenia (age-related muscle loss). A recent mouse study found that animals without gut microbes had significantly weaker muscles than normal mice . Germ-free mice (raised in sterile conditions)...
Bonobos are famous for having liberal sexual behaviors, but new field research reveals why female bonobos particularly favor sex with each other. In a wild bonobo community observed for a year, researchers found that adult females engaged in same-sex genital rubbing far more often than male...
