Mangrove forests, once considered one of the world's most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset ...

Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ...

Designing surfaces that precisely control how light behaves at the nanoscale is tricky. Optical Fourier surfaces, which are nanostructured gratings that redistribute light into specific directions and wavelengths, hold enormous ...

Using box jellyfish as an example, researchers from Kiel University show how the physics of density, not behavior or physiology, can prevent animals from reaching the surface even as they actively swim upward.

In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a vast ocean once covered the landing ...

Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found pieces of granite that seemingly had no business being there. Those unexpected intrusions turned ...

For the first time, mighty ocean waves generated in the Southern Ocean have been accurately measured all the way to the tiny ripples they form on the shores of Alaska. Professor Ian Young, from the University of Melbourne's ...

The study "Homo cooperans: Understanding the nature of human cooperation" arrives at a clear result: 69% of study participants chose to cooperate. At the same time, the study published in the journal Science shows that people ...

University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria ...

Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than ...

Fish that split their lives between fresh and salt water often face obstacles getting back and forth. Dams and roads fracture river networks and interfere with traditional migratory routes, sparking concerns about fish health ...
