Philadelphia, December 4, 2018 -- Using an animal model of chronic stress, researchers at The Ohio State University have shown that the immune cells of the brain, called microglia, hold unique signatures of chronic stress that leave the animal more sensitive to future stressful experiences, evident by increased anxiety and immune responses. Eliminating microglia so that these "stress memories" could not be maintained did not prevent the increased anxiety in response to later stress but did prevent the hypersensitive immune response.
A unique experiment that explored how well algae grows in specific regions of the United States yielded data that could prove useful as the industry moves forward, according to research from the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) and Arizona State University (ASU).
COLUMBUS, Ohio - There are many organizations monitoring endangered species such as elephants and tigers, but what about the millions of other species on the planet -- ones that most people have never heard of or don't think about? How do scientists assess the threat level of, say, the plicate rocksnail, Caribbean spiny lobster or Torrey pine tree?
BLOOMINGTON, Ind. - In a new study, Indiana University scientists found toxic flame retardants in newly manufactured children's car seats, sparking concerns about children's health. Of the 18 children's car seats tested, 15 contained new or traditional hazardous flame retardant chemicals.
Scientists studying the digestive system of a curious wood-eating crustacean have discovered it may hold the key to sustainably converting wood into biofuel.
Gribble are small marine invertebrates that have evolved to perform an important ecological role eating the abundant supplies of wood washed into the sea from river estuaries.
They can also be something of a marine menace, consuming the wood of boats and piers and causing considerable damage in the process.
The research, led by the University of Plymouth, examined the uptake of nanoparticles by a commercially important mollusc, the great scallop (Pecten maximus).
After six hours exposure in the laboratory, billions of particles measuring 250nm (around 0.00025mm) had accumulated within the scallop's intestines.
However, considerably more even smaller particles measuring 20nm (0.00002mm) had become dispersed throughout the body including the kidney, gill, muscle and other organs.
TROY, N.Y. -- Small animals at the base of the freshwater food chain can rapidly adapt to salt pollution - from sources like winter road deicing, agriculture, and mining - but at a price. In a special December edition of Philosophical Transactions of the Royal Society B devoted to freshwater salt pollution, research shows that salt-adapted freshwater zooplankton grow 65 percent slower than regular zooplankton. Their slow growth cascades down the food chain in environments polluted with the most commonly found salt, triggering algal blooms.
A recent study led by University of Maryland researchers found that streams and rivers across the United States have become saltier and more alkaline over the past 50 years, thanks to road deicers, fertilizers and other salty compounds that humans indirectly release into waterways. The team named this effect "Freshwater Salinization Syndrome."
MIAMI--A new study helping to improve how sustainability is measured for popular reef fish could help better assess the eco-friendly seafood options at the dinner table.
A team of researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and NOAA Fisheries tested their newly developed fishery risk assessment method on groupers and snappers in the Florida Keys to determine if these tropical reef fish are being managed sustainability.
