Bats vs. Dolphins: Ultimate battle of sonar systems

Active sensors are incorporated into a number of technologies, such as meteorology devices and self-driving cars, and use the echo from sound, radio or light waves to locate objects. But despite nearly a century of development, these active sensing technologies still fail to replicate the performance of sonars (sound waves) used in the biological world...

Warming oceans lead to more fur seal deaths from hookworm infection

Rising ocean temperatures are putting fur seal pups at greater risk of death from hookworm infections, according to new findings published in eLife.

The results shed new light on how warmer oceans can alter specific physiological processes in marine mammals, and suggest that infectious diseases could cause higher mortality rates if temperatures keep rising.

"Increasing ocean temperatures...

Eat your vegetables (and fish): Another reason why they may promote heart health

Elevated levels of trimethylamine N-oxide (TMAO) -- a compound linked with the consumption of fish, seafood and a primarily vegetarian diet -- may reduce hypertension-related heart disease symptoms. New research in rats finds that low-dose treatment with TMAO reduced heart thickening (cardiac fibrosis) and markers of heart failure in an animal model of hypertension. The...
