UCLA findings suggests possible new treatment for depression, other disorders
What makes us happy? Family? Money? Love? How about a peptide?
The neurochemical changes underlying human emotions and social behavior are largely unknown. Now though, for the first time in humans, scientists at UCLA have measured the release of a specific peptide, a neurotransmitter called hypocretin, that greatly increased when subjects were happy but decreased when they were sad.

COLUMBIA, Mo. – The University of Missouri has Jesse Hall, Faurot Field, Memorial Union and the Columns. Now, MU has its own bug. An MU researcher has discovered a new insect on campus and given it a Mizzou name. Ben Puttler, assistant professor emeritus of plant sciences at the College of Agriculture, Food and Natural Resources, first discovered Aphis Mizzou in 2005 while conducting research on wasps on the MU campus.
The insect, Aphis Mizzou, is a member of the aphid family of bugs. Aphids are tiny insects that live by feeding on the sap of plants. Nearly all annual and perennial plants, including shrubs and trees, are potential hosts for aphids. When feeding on these plants, aphids can crumple leaves, distort plant tissue and bend stems. There are 5,000 species of aphids known in the world, but only 150 live in North America. (more…)
A study of its basin paves the way for cleaner water everywhere
The Minnesota River’s usually placid surface belies its status as a river —and a watershed—in need of help.
The river is naturally prone to heavy sediment loads. It runs through rich glacial deposits, in a channel carved by a catastrophic flood at the end of the last ice age, when a large lake formed by glacial meltwater gave way.(more…)
More than 190,000 people have been killed in the 10 years since the war in Iraq began. The war will cost the U.S. $2.2 trillion, including substantial costs for veterans care through 2053, far exceeding the initial government estimate of $50 to $60 billion, according to a new report by scholars with the “Costs of War” project at Brown University’s Watson Institute for International Studies. The 10th anniversary of the U.S. invasion of Iraq is March 19, 2013.
PROVIDENCE, R.I. [Brown University] — Ten years after the U.S.-led invasion of Iraq on March 19, 2003, researchers have released the first comprehensive analysis of direct and indirect human and economic costs of the war that followed. According to the report, the war has killed at least 190,000 people, including men and women in uniform, contractors, and civilians and will cost the United States $2.2 trillion — a figure that far exceeds the initial 2002 estimates by the U.S. Office of Management and Budget of $50 to $60 billion.

COLUMBUS, Ohio – Scientists have delved deeper into the evolutionary history of the fruit fly than ever before to reveal the genetic activity that led to the development of wings – a key to the insect’s ability to survive.(more…)
ANN ARBOR — Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.
The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer’s disease and other neurodegenerative conditions. (more…)
When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope, astronomers at the University of Chicago’s Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance.
The light sources interfered with efforts to measure more precisely the cosmic microwave background—the afterglow of the big bang. But the astronomers soon realized that they had made a rare find in South Pole Telescope’s large survey of the sky. The spectra of some of the bright objects, which is the rainbow of light they emit, were inconsistent with what astronomers expected from the well-known population of radio galaxies. (more…)
In January, 60 young Tanzanian children began attending school for the first time, thanks to a project led by Michigan State University.
MSU and its partners in the Tanzanian Partnership Program built a new schoolon 100 acres donated by two village elders in a sub-village of Milola known as Ngwenya. Construction funds were provided by the TAG Philanthropic Foundation, based in New York. (more…)
