Fog may look empty and gray, but scientists say it's more like a floating, living bacterial community. In a two-year study of 32 stagnant-air fog events in central Pennsylvania, researchers from Arizona State University and Susquehanna University found that about 1% of individual fog droplets contained bacteria enough, when taken...

Nature - 1 day 5 hours agoSmartphone users' heart rate and resting heart rate can be estimated across the skin-tone spectrum.
Nature - 1 day 5 hours agoResting heart rate (RHR) is a key biomarker of cardiovascular health and mortality1–3, but passively tracking it longitudinally generally requires a wearable device, limiting its availability. Here we present passive heart-rate monitoring (PHRM), a deep-learning system that uses facial video-based photoplethysmography for passive measurements of heart rate (HR) and RHR during everyday smartphone interactions. Our system was developed using 192,353 videos from 485 participants and validated...

Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged mice, and then dropped again in very old mice. The key appears to be a special type of immune cell that helps keep cancer dormant and prevents it from spreading.

A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world's oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium carbonate, a mineral that plays an important role in ocean health and carbon storage. For years, researchers believed fish handled this process on their own, but the new findings point to a hidden partnership between fish and microbes.
