Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
Chesapeake Bay cleanup going in "right direction," thanks partly to Pennsylvania
Chesapeake Bay cleanup is behind schedule but "going in the right direction," largely because Pennsylvania has stepped up efforts to curb the flow of fertilizer and other runoff into bay tributaries, an Environmental Protection Agency official told M.....»»
Ingredients used in chewing gum help tilapia survive cold climates
Two common ingredients in ordinary chewing gum—Arabic gum and lecithin—have been found to help improve the overall health of tilapia, helping these fish survive better even in cold climates. This discovery paves the way for raising tilapia for fo.....»»
Evaluating the flow of information for high-impact weather events

A secret recipe for colorful and versatile animal crystals
What do fish, chameleons, crabs and Walter White, the chemistry teacher from "Breaking Bad," all have in common? The answer is that they all know how to make crystals. But, unlike the incorrigible White, who manufactured mind-altering methamphetamine.....»»
3D field-based tracking and field experiments of octopus and fish unlock the secrets of multispecies hunting
The diving gear is on, the cameras are ready—biologist Eduardo Sampaio and his colleagues are set to go. They dive in the Red Sea, scanning left and right underwater—and wonder: Where can an octopus hunting be found? Finally, they spot one. The t.....»»
Study shows artificial light at night changes the behavior of fish, even into the next generation
Scientists have shown that light pollution—especially light in the blue spectrum—can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring. The team from China has studied how female zebrafish responded.....»»
Scientists propose new "golden rules" for sustainable fishing
Top ocean experts have published a report that redefines the concept of "sustainable fishing" and proposes 11 "golden rules" that radically challenge the flawed approach that currently prevails in fisheries management......»»
