UA Scientists Help Discover Most Abundant Ocean Virus

By Guest PostFebruary 14, 2013Scienceocean living bacterium, ocean virus, pelagiphages viruses

Researchers have discovered four previously unknown viruses that infect the Earth’s most abundant organism, the marine bacterium SAR11. Because of their huge numbers, these tiny players have critical roles in the global cycle of carbon and other nutrients

The greatest battle in Earth’s history has been going on for hundreds of millions of years, isn’t over yet, and until now no one knew it existed, scientists reported today in the journal Nature. (more…)

Death and dying 2000-2009: Hospice Use Rises; So Does Aggressive Care

A study in the Journal of the American Medical Association documents an increase in hospice use over the last decade but also finds more ICU utilization, more repeat hospitalizations, and more late health care transitions. The data raises concern about whether aggressive care and burdensome transitions at the end of life are consistent with the wishes of patients or those of their family members.

PROVIDENCE, R.I. [Brown University] — A study published Feb. 6 in the Journal of the American Medical Association finds that while more seniors are dying with hospice care than a decade ago, they are increasingly doing so for very few days right after being in intensive care. The story told by the data, said the study’s lead author, is that for many seniors palliative care happens only as an afterthought. (more…)

PASADENA, Calif. – A new study using data from a pair of gravity-measuring NASA satellites finds that large parts of the arid Middle East region lost freshwater reserves rapidly during the past decade.

Scientists at the University of California, Irvine; NASA’s Goddard Space Flight Center in Greenbelt, Md.; and the National Center for Atmospheric Research in Boulder, Colo., found during a seven-year period beginning in 2003 that parts of Turkey, Syria, Iraq and Iran along the Tigris and Euphrates river basins lost 117 million acre feet (144 cubic kilometers) of total stored freshwater. That is almost the amount of water in the Dead Sea. The researchers attribute about 60 percent of the loss to pumping of groundwater from underground reservoirs. (more…)

UD’s Schmidt studies heat stress, disease resistance in African chickens

Last fall, the University of Delaware’s Carl Schmidt took a trip to Uganda with a team of researchers from Iowa State University and North Carolina State University to get genetic samples from African chickens. The goal was to compare and contrast their genes to one another, and also to American broiler chickens, to gauge how the two species’ genetic makeup helps them cope with heat stress, as well as susceptibility and resistance to different diseases.

Zinc Helps against Infection by Tapping Brakes in Immune Response

COLUMBUS, Ohio – New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly.

Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc then interacts with a process that is vital to the fight against infection and by doing so helps balance the immune response. (more…)
