Why do people living at high altitudes have better glucose control? The answer was in plain sight
In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking observations from that work was a dramatic drop in circulating blood sugar.

Scientists discover the body’s hidden “off switch” for inflammation
A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and
Particles don't always go with the flow (and why that matters)
It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and other complex materials. But a team of Yale researchers led by Professor Amir Pahlavan shows that even gentle chemical gradients, such as a small change
Hiding in plain sight: Discovery of cryptic species could double the number of vertebrates
There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's not because of any errors or miscalculation, but because thousands of species

Brain development may continue into your 30s, new research shows
That viral claim that your frontal lobe “isn’t fully developed until 25” turns out to be more myth than milestone. Early brain scans showed that gray matter changes dramatically through the teen years, and because studies stopped around age 20, scientists estimated development
Ancient DNA solves 5,500 year old burial mystery in Sweden
Ancient DNA from a Stone Age burial site in Sweden shows that families 5,500 years ago were more complex than expected. Many individuals buried together were not immediate family, but second- or third-degree relatives. One grave held a young woman alongside two children who
Ancient drought may have wiped out the real-life hobbits 61,000 years ago
A massive, centuries-long drought may have driven the extinction of the “hobbits” of Flores. Climate records preserved in cave formations show rainfall plummeted just as the small human species disappeared. At the same time, pygmy elephants they depended on declined sharply as
