You could argue that those would actually improve average longevity far more than anti-ageing research, by reducing infant mortality and infectious disease and so on. … Read more

Metabolic details matter to predict health in the modern world, Ocobock says. The same genetic programming that arose to protect someone in the Arctic—like high BMI and faster metabolism—could become liabilities. Many of Ocobock’s study subjects have been overweight and obese with normal cholesterol and blood sugar. Being “fat but fit,” which has been beneficial … Read more
“It was pretty amazing how well the experimental data and numerical simulation matched,” Eckert said. In fact, it matched so closely that Carenza’s first response was that it must be wrong. The team jokingly worried that a peer reviewer might think they’d cheated. “It really was that beautiful,” Carenza said. The observations answer a “long-standing … Read more
Digital health company Celero Systems is developing an electronic pill that can measure heart rate, breathing rate, and core temperature—from inside the human stomach. As a first step, the company envisions people with ongoing conditions using the digital capsule to monitor their vital signs at home. But in the future, they hope to use it … Read more

First it has to enter the body, bypassing natural barriers such as skin, mucus, cilia, and stomach acid. Then it needs to reproduce; some bacteria and parasites can do this virtually anywhere in … Read more
This story originally appeared in Hakai and is part of the Climate Desk collaboration. Arah Narida leans over a microscope to gaze into a plastic petri dish containing a hood coral.

Feline researchers have long believed that purring is produced by voluntary muscle contractions, but a new report indicates that this vibration in the larynx of cats may be explained by the myoelastic aerodynamic theory of phonation. Studies on the complex action that produces a unique vibration in the larynx of cats—known as purring to most … Read more
