NOAA's Marine Debris Program reports on the national issue of derelict fishing traps

August 27, 2014 10:42 am | by EurekAlert! | News | Comments

Thousands of fishing traps are lost or abandoned each year in U.S. waters and become what are known as derelict traps, which continue to catch fish, crabs, and other species such as turtles. These traps result in losses to habitat, fisheries, and the watermen who depend on the resources--losses that are largely preventable, according to a newly published NOAA study....

DTU researchers film protein quake for the first time

August 27, 2014 10:21 am | by EurekAlert! | News | Comments

One of nature's mysteries is how plants survive impact by the huge amounts of energy contained in the sun's rays, while using this energy for photosynthesis. The hypothesis is that the light-absorbing proteins in the plant's blades quickly dissipate the energy throughout the entire protein molecule through so-called protein quakes....
