In 1962, when environmentalist and author Rachel Carson penned "Silent Spring," alerting the world to the dangers of the pesticide DDT, it was the reproductive threat to birds – the bald eagle in particular – that spurred people to action.
Six decades later, Rutgers University–New Brunswick researchers are taking the measure of another global environmental pollutant by drawing parallels to the crisis Carson identified. This time, the pollutant is mercury, and the sentinels are penguins living in the farthest reaches of the Antarctic Peninsula.
“With mercury, there’s an analogy to DDT,” said John Reinfelder, a professor in the Department of Environmental Sciences at the Rutgers School of Environmental and Biological Sciences, and co-author of a study published in Science of the Total Environment examining mercury levels in the flightless, aquatic birds.
A hopping, insect-sized robot can jump over gaps or obstacles, traverse rough, slippery, or slanted surfaces, and perform aerial acrobatic maneuvers, while using a fraction of the energy required for flying microbots.
A Worcester Polytechnic Institute (WPI) researcher is developing a new class of medical adhesives by bringing together hydrogels and glue-like polymers to safely and reliably connect human tissues to therapeutic devices implanted in the body, such as pacemakers, insulin pumps, and artificial joints.
About 131 million years ago, an 11-foot-long ichthyosaur slammed snout first into the seafloor and was rapidly buried by sediments — a sequence of events that helped preserve not only her skeleton, but that of her unborn baby, along with the remains of her last meal. These details are part of a new study from an international team published in the Journal of Vertebrate Paleontology about the pregnant marine reptile, which the team named Fiona.
