Swordfish may be using deep dives to navigate the open ocean

Swordfish spend much of their time hunting prey about 600 meters (1,970 feet) below the surface in the ocean twilight zone, but occasionally, they reach depths of more than 1,000 meters (3,280 feet). Now, scientists from the Woods Hole Oceanographic Institution (WHOI) are

How the cosmic environment depletes galaxies of their gas

An international team of researchers, led by Jonathan Freundlich (University of Strasbourg, Astronomical Observatory), has revealed how a dense cosmic environment depletes galaxies of their gas. By mapping the molecular gas in a galaxy group located 7 billion light-years away,

Poles of bacteria imaged in fine detail for the first time

The poles, or ends, of rod-shaped bacteria have been imaged at molecular resolution for the first time in a new study led by UCL (University College London) researchers. The study, published in the journal Nature Communications, used a new technique to keep live bacteria in

Protein tails help shape mosquito cell-to-cell channels

Cells share small molecules with their neighbors through tiny tunnels made of proteins arranged in a ring. Research at Nagoya University suggests that the tails of the proteins must link up to form an inner ring for the tunnel to become evenly round—a previously unknown step in

A new method for tracking climate change and air pollution

Two papers by Prof. Thomas A. Weber develop a rank-based method to track environmental change. They apply the idea to follow Geneva's warming climate, and generalize the approach to quantify shifts in spatial air-pollution exposure across Switzerland. The method compares

Airborne imaging explores a mosaic of thawing permafrost

Permafrost in many of Earth's northern regions is thawing, a process that unlocks greenhouse gases, threatens infrastructure, and could alter landscapes and ecosystems. The Arctic and subarctic are vast, and gaining a comprehensive picture of permafrost distribution is

Reef biodiversity accounting to help scale up restoration

To encourage new investments in more effective reef restoration activities, Australian scientists are recommending a new way of measuring biodiversity on coral reefs. A team of Australian environmental scientists led by James Cook University's distinguished professor Morgan
