Pacemaker powered by light eliminates need for batteries and allows the heart to function more naturally − new research

Researchers designed an ultrathin pacemaker that can be implanted via minimally invasive techniques, potentially improving recovery time and reducing the risk of complications.

Sharks, turtles and other sea creatures face greater risk from industrial fishing than previously thought − we estimated added pressure from ‘dark’ fishing vessels

The toll on wildlife from illegal fishing, bycatch and entanglement in fishing gear is likely underestimated, because it doesn’t account for ‘dark’ fishing vessels, a new study finds.

Flowers grown floating on polluted waterways can help clean up nutrient runoff and turn a profit

Phosphorus and nitrogen contribute to water pollution and cause harmful algal blooms. New research shows how mats of floating flower beds can take advantage of these nutrients while cleaning the water.

AI can help − and hurt − student creativity

A study in which students brainstormed all the uses of a paper clip shows that AI can both enhance and harm the creative process.

Why don’t fruit bats get diabetes? New understanding of how they’ve adapted to a high-sugar diet could lead to treatments for people

Fruit bats can eat up to twice their body weight in fruit a day. But their genes and cells evolved to process all that sugar without any health consequences − a feat drug developers can learn from.
