Warming seas might also look less colorful to some fish: Here's why that matters

Posted: 21 Apr 2021 05:01 PM PDT

Climate change is driving some fish into cooler, deeper waters. Now they may be faced with another challenge: how to make sense of a world drained of color. Researchers report that even small increases in depth could make it harder for fish to discern the hues they use to find food, friends and family. They are trying to predict which species will be most impacted, and whether they'll be able to adapt.

Collaborative research could help fine-tune the production of antimalarials, chemo drugs

Posted: 21 Apr 2021 05:01 PM PDT

Much of common pharmaceutical development today is the product of laborious cycles of tweaking and optimization.

Study explains 'cocktail party effect' in hearing impairment

Posted: 21 Apr 2021 01:00 PM PDT

Plenty of people struggle to make sense of a multitude of converging voices in a crowded room. Commonly known as the 'cocktail party effect,' people with hearing loss find it's especially difficult to understand speech in a noisy environment. New research suggests that, for some listeners, this may have less to do with actually discerning sounds. Instead, it may be a processing problem in which two ears blend different sounds together - a condition known as binaural pitch fusion.
