Today’s most successful fish weren’t always evolutionary standouts

Take a glance around the oceans, rivers and lakes of today and you'll confront an astonishing diversity of fish, from narrow-bodied eels to the 25-foot-long giant oarfish to delicate, fluttering seahorses. The vast majority of fish alive today -- approximately 96 percent -- are known as teleosts, a group of ray-finned fish that emerged 260 million years ago.

Science at cusp of ‘transformational’ grasp of life via cell modeling

Advances in molecular biology and computer science around the world soon may lead to a three-dimensional computer model of a cell, the fundamental unit of life, outlines a new report. According to the authors, the development could herald a new era for biological research, medical science, and human and animal health.

Placodonts illuminate a crushing evolutionary question

Early marijuana use associated with abnormal brain function, lower IQ

In a new study, scientists have discovered that early marijuana use may result in abnormal brain function and lower IQ.

How do birds dive safely at high speeds? New research explains

To surprise their prey, some species of seabirds dive into the water at speeds greater than 50 miles per hour. A human diver entering the water that fast would likely sustain serious injuries, but birds, such as gannets and boobies, pull off these dives safely in spite of their slender necks.

Carbon dioxide levels race past troubling milestone

Carbon dioxide levels in Earth's atmosphere passed a troubling milestone for good this summer and locked in levels of the heat-trapping gas not seen for millions of years.

Beaver-inspired wetsuits in the works

Beavers and sea otters lack the thick layer of blubber that insulates walruses and whales. And yet these small, semiaquatic mammals can keep warm and even dry while diving, by trapping warm pockets of air in dense layers of fur. Inspired by these fuzzy swimmers, engineers have now fabricated fur-like, rubbery pelts and used them to identify a mechanism by which air is trapped between individual hairs when the pelts are plunged into liquid.
