Researchers discovered five new species of black corals, including this
Hexapathes bikofskii growing out of a nautilus shell more than 2,500 feet (760 meters) below the surface.
Black corals provide critical habitat for many creatures that live in the dark, often barren, deep sea, and researchers are learning more about these rare corals with every dive.
New research shows just 2% of the Great Barrier Reef remains untouched by bleaching since 1998. Its future survival depends on how much higher we allow global temperatures to rise.
Drilling 139 meters down to volcanic rock provided scientists with a million-year environmental record.

A new environmental record for a prehistoric site in Kenya helped researchers figure out how external conditions influenced which of our ancient ancestors lived there, with what way of life.
Eelgrasses covered with small snails, which keep the leaves clean by feeding on algae that live on them.
Healthy seagrasses form underwater meadows teeming with fish and shellfish. A successful large-scale restoration project in Virginia could become a model for reseeding damaged seagrass beds worldwide.
There are fundamental knowledge gaps around coral in the Great Barrier Reef, including how many species live there and where they’re found. Our new study finally starts to fill those gaps.
Footprints, preserved in solidified ash, hint at human behavior from as long as 19,000 years ago.
The footprints of over 20 different prehistoric people, pressed into volcanic ash thousands of years ago in Tanzania, show possible evidence for sexual division of labor in this ancient community.

Bagaimana paus, yang hanya memakan makhluk kecil, mampu berevolusi menjadi makhluk terbesar di dunia? Dan mengapa mereka tidak bertambah besar?
How did whales that feed on tiny prey evolve into the largest creatures on Earth? And why don’t they get even bigger?
Rules put into place to protect endangered species have harmed people who depend on nature.
Two scholars report on how conservation policies designed to protect reindeer are harming the nomadic Tsaatan people who rely on them.

A 19th-century volume contained a mystery for two historians who combined their knowledge to tell the story of the women and their contributions to American democracy.
Thalidomide was initially marketed for daytime use, first as a flu treatment, then as ain aid to reduce stress and anxiety.
Thalidomide was developed in an era of widespread enthusiasm – but little critical attention – for pharmaceutical therapies.
A different perspective on fracking: wells in the Jonah Field, Wyoming.
The rise of hydraulic fracturing, or fracking, has ushered in an era of intense drilling that has been called the great shale gas rush. Fracking allows oil and natural gas to be extracted from horizontal…
Coral reefs face a major species extinction crisis.
The Great Barrier Reef is worth billions to Australia’s economy and is one of the world’s most significant natural features. We have a responsibility to protect it, and our other reefs, from the warming…
