NASA's Fermi Finds Possible Dark Matter Ties in Andromeda Galaxy
February 21, 2017 04:46 PM - NASA/Goddard Space Flight Center

NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Dying Patients Who Received Palliative Care Visited the ER Less
February 21, 2017 04:44 PM - American College of Emergency Physicians

Community-based palliative care – care delivered at home, not the hospital – was associated with a 50 percent reduction in emergency department visits for patients in their last year of life.  The results of an Australian study were published online February 3rd in Annals of Emergency Medicine(“The Association of Community-Based Palliative Care with Reduced Emergency Department Visits in the Last Year of Life Varies by Patient Factors”).

Winners, losers among fish when landscape undergoes change

As humans build roads, construct buildings and develop land for agriculture, freshwater ecosystems respond - but not always in the ways one might expect.

Offshore Wind Push

Injecting large amounts of offshore wind power into the U.S. electrical grid is manageable, will cut electricity costs, and will reduce pollution compared to current fossil fuel sources, according to researchers from the University of Delaware and Princeton University who have completed a first-of-its-kind simulation with the electric power industry.

Over time, nuisance flooding can cost more than extreme, infrequent events

Global climate change is being felt in many coastal communities of the United States, not always in the form of big weather disasters but as a steady drip, drip, drip of nuisance flooding.

Colorado River Flows to Keep Shrinking as Climate Warms

Warming in the 21st century reduced Colorado River flows by at least 0.5 million acre-feet, about the amount of water used by 2 million people for one year, according to new research from the University of Arizona and Colorado State University.

New URI professor examining effects of climate change on coral reefs, shellfish
February 21, 2017 01:16 PM - University of Rhode Island

The newest professor in the University of Rhode Island’s College of the Environment and Life Sciences, Hollie Putnam, thinks some corals and shellfish might have good enough “memories” to buffer the changes in ocean chemistry that are resulting from global climate change.

A native of Minnesota who earned a doctorate at the University of Hawaii, Putnam is studying how a wide variety of marine organisms are responding to changes in their environment. Focusing on reef-building corals and other shelled creatures that are threatened by increasing temperatures and ocean acidification, she is testing them to determine how species may acclimatize to the new circumstances.

Researcher Unveils Tool for Cleaner Long Island Sound
February 21, 2017 11:56 AM - Kim Krieger via University of Connecticut

A new model released this week by UConn ecologist Jamie Vaudrey pinpoints sources of nitrogen pollution along Long Island Sound, and shows municipalities what they might do to alleviate it. Vaudrey presented her research Feb. 19 at the AAAS annual meeting in Boston.

Long Island Sound is an estuary of the Atlantic Ocean bordered by Connecticut to the north, New York City to the west, and Long Island to the south. The Sound is home to dozens of species of birds, 170 species of fish, and more than 1,200 species of invertebrates. Historically it has supported rich recreational and commercial fisheries for lobster, oysters, blue crabs, scallops, striped bass, flounder, and bluefish.

MORE WARM-DWELLING ANIMALS AND PLANTS AS A RESULT OF CLIMATE CHANGE
February 21, 2017 11:47 AM - Senckenberg Research Institute and Natural History Museum

Since 1980, populations of warm-dwelling species in Germany have increased. The trend is particularly strong among warm-dwelling terrestrial species, as shown by the most comprehensive study across ecosystems in this regard to date. The most obvious increases occurred among warm-dwelling birds, butterflies, beetles, soil organisms and lichens according to the study published recently in the scientific journal “Nature Ecology & Evolution” led by Senckenberg scientists. Thus, it appears possible that rising temperatures due to the climate change have had a widespread impact on the population trends of animals in the past 30 years.

Fluorescence method detects mercury contamination in fish
February 21, 2017 11:25 AM - Plataforma SINC

Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and tuna. According to the conclusions of another Spanish study, mercury exposure is linked to reduced foetal and placental growth in pregnant women.

The presence of the toxic metal mercury in the environment comes from natural sources, however, in the last decades industrial waste has caused an increase in concentrations of the metal in some areas of the sea. In the food chain, mercury can be diluted either in organic form as methylmercury (MeHg+) or as an inorganic salt, the cation Hg2+.
