Studies and Analyses

Long before a Hollywood blockbuster about catastrophic climate change packed cinema multiplexes this spring, researchers at the top of the world, supported by the National Science Foundation (NSF), were using an array of scientific tools to build a comprehensive scientific picture of environmental change in the Arctic and what it may mean for the rest of the globe. Led by oceanographer James Morison, of the University of Washington, NSF-supported scientists from Oregon State University, as we

Whenever a hurricane races across the Atlantic Ocean, chances are phytoplankton will bloom behind it. According to a new study using NASA satellite data, these phytoplankton blooms may also affect the Earth’s climate and carbon cycle.

Dr. Steven Babin, a researcher at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., studied 13 North Atlantic hurricanes between 1998 and 2001. Ocean color data from the SeaWiFS instrument on the SeaStar satellite were used to analyze l

Acrylamide (AA)is a substance that has found widespread application in industry, e.g. for the purification of drinking water and in food packaging. Due to its toxicological properties, legal limits have been set both for drinking water and for migration into food.

Following a request of the participants of the European Workshop on “Analytical methods for the acrylamide determination in food”, the Institute for Reference Materials and Measurements (IRMM) of the European Commission’s Directo

Iowa City Veterans Affairs (VA) Medical Center and University of Iowa (UI) researchers have unlocked part of the mystery of how a harmless virus known as GBV-C slows the progression of HIV and prolongs survival for many patients. The report appears in the June 19 issue of The Lancet, the leading British medical journal.

The findings provide the clearest insight yet into the biological mechanisms of GBV-C, a benign cousin of the hepatitis C virus. The virus infects almost all HIV patients

Sometimes it takes time to uncover nature’s secrets. Take the case of callimicos, also called Goeldi’s monkeys, a reclusive and diminutive South American primate. Discovered a century ago by Swiss naturalist Emil August Goeldi, the animals were once considered to be a possible “missing link” between small and large New World monkeys.
But new findings from the first long-term studies of the monkeys in the wild seem to indicate that this is not the case, although the animals have a uniqu

New research at the University of North Carolina at Chapel Hill provides insights into the fundamental mechanisms controlling blood vessel formation and may have implications for therapies such as non-surgical restoration of circulation.

The study findings appear in the June 15 issue of the journal Blood.

Blood vessel formation, or angiogenesis, is an integral part of normal organ development and function. It also contributes to abnormal conditions, particularly tumor formation an
