Researchers have discovered that variations in corn snake skin patterns are driven by a single gene, CLCN2, which influences how pigment cells arrange during development. Mutations and retrotransposon insertions in this gene produce the motley and stripe morphs, showing how ion channels and mobile DNA elements can generate new evolutionary traits.

Scientists modeled whether Titan’s subsurface ocean could support microbial life through fermentation of glycine, a simple amino acid thought to form in its atmosphere. Their results suggest such metabolism is theoretically possible but would only sustain an extremely sparse biosphere, shaping expectations for future life-detection missions like NASA’s Dragonfly.

Researchers at Cambridge and Birmingham have developed a flexible handheld patch with six vibration sensors that records high-quality heart sounds, even through clothing. Tested on volunteers, the device outperformed some digital stethoscopes and could make heart disease screening more accessible, comfortable, and affordable if future trials succeed.

Neuroscientists propose a new theory that serotonin neurons encode a “prospective value signal,” forecasting near-future rewards and punishments rather than simply reacting to the present. This model helps explain decades of puzzling serotonin data, linking the chemical to anticipation, patience, and mental health.

New research shows that Birt-Hogg-Dubé syndrome, once thought to affect about 1 in 200,000 people, may actually be as common as 1 in 3,000. Large-scale DNA studies reveal that while FLCN mutations raise risks of lung collapse and kidney cancer, outcomes vary widely, reshaping how doctors may diagnose and monitor the condition.
