How Algae Communicate

Smithsonian scientist Valerie Paul studies the ways marine biochemicals can potentially help restore coral reefs and create new biomedicine

The Algodón River flows through a forest of the Amazon Basin in the remote northeastern corner of Peru. Scientists collected and analyzed a series of ten roughly 3-foot-long soil cores from three sites, each located at least a half-mile away from river courses and floodplains.

Scientists say the Boltysh crater in Ukraine formed well after the impact in Mexico that caused the dinosaurs to go extinct

Small family-run dive tour operations in Mexico have been found to give more back to their communities than large foreign-owned businesses.

In Mexico, Dive Tourism Is Worth as Much as Fishing

Researchers estimate diving and snorkeling bring in up to $725 million annually

An effort to bring wild bison to the Great Plains aims to restore one of the world’s most endangered ecosystems

Combining carbon dioxide and calcium creates calcium carbonate rocks such as limestone.

To Combat Climate Change, Researchers Want to Pull Carbon Dioxide From the Ocean and Turn It Into Rock

Running seawater through an ocean carbon capture plant could chemically convert carbon dioxide to limestone on a grand scale

While this year’s Arctic sea ice extended further than last year’s, there still wasn’t as much of it as there was only two decades ago. Thinner and younger sea ice in winter and less ice in the summer are two of the many elements of the Arctic’s new reality.

Climate Change Redefines Meaning of Normal in the Arctic

As Earth’s climate changes, people around the world are witnessing insidious changes and responding to their new normal

Climate change is causing oceans to warm, which in turn affects fish and fishers. Now, scientists are turning towards management strategies to protect species and the industry.
