Student winners from across the globe, including United States and Thailand, are honored at the 10th anniversary of the Imagine Cup

SYDNEY — July 10, 2012 — Microsoft Corp. announced the winners of the 10th annual Imagine Cup, the world’s premier student technology competition, honoring student technology innovations that address the world’s toughest problems. The winning Software Design project developed by Ukrainian Team quadSquad allows deaf individuals to communicate verbally using custom-designed sensory gloves and a smartphone application to translate sign language gestures into speech. Games focused on the environment from Thailand team TANG Thai and math education from U.S. team Drexel Dragons won the two Game Design competitions. (more…)

Diagnostic Technique Uses Immune Cell DNA

By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique, described in two recent papers, potentially valuable not only for research but also for diagnostics and treatment monitoring.

PROVIDENCE, R.I. [Brown University] — When a person is sick, there is a tell-tale sign in their blood: a different mix of the various types of immune cells called leukocytes. A group of scientists at several institutions including Brown University has discovered a way to determine that mix from the DNA in archival or fresh blood samples, potentially providing a practical new technology not only for medical research but also for clinical diagnosis and treatment monitoring of ailments including some cancers.

Jekyll and Hyde Bacteria Aids or Kills, Depending on Chance

EAST LANSING, Mich. — Living in the guts of worms are seemingly innocuous bacteria that contribute to their survival. With a flip of a switch, however, these same bacteria transform from harmless microbes into deadly insecticides. (more…)

“Self-Distancing” Can Help People Calm Aggressive Reactions, Study Finds

COLUMBUS, Ohio – A new study reveals a simple strategy that people can use to minimize how angry and aggressive they get when they are provoked by others.

When someone makes you angry, try to pretend you’re viewing the scene at a distance – in other words, you are an observer rather than a participant in this stressful situation. Then, from that distanced perspective, try to understand your feelings.

Researchers call this strategy “self-distancing.” (more…)

Astronomers Discover Houdini-Like Vanishing Act in Space

Astronomers report a baffling discovery never seen before: An extraordinary amount of dust around a nearby star has mysteriously disappeared.

“It’s like the classic magician’s trick — now you see it, now you don’t,” said Carl Melis, a postdoctoral scholar at UC San Diego and lead author of the research. “Only in this case, we’re talking about enough dust to fill an inner solar system, and it really is gone!”

“It’s as if the rings around Saturn had disappeared,” said co-author Benjamin Zuckerman, a UCLA professor of physics and astronomy. “This is even more shocking because the dusty disc of rocky debris was bigger and much more massive than Saturn’s rings. The disc around this star, if it were in our solar system, would have extended from the sun halfway out to Earth, near the orbit of Mercury.” (more…)

Nitrogen Pollution Changing Rocky Mountain National Park Vegetation, Says CU-Boulder Study

A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park. (more…)

UCLA Study Looks at Why Heart Attacks Cause so Much More Damage in Late Pregnancy

Heart attacks during pregnancy are uncommon, but the prevalence of heart disease in pregnant mothers has increased over the past decade as more women delay pregnancy until they are older. These women, who are generally less physically active than their younger peers, tend to have higher cholesterol levels and are at greater risk of heart disease and diabetes.

While research has shown that the heart typically functions better during pregnancy due to a rise in cardiac pumping capacity to meet increased demands, a new UCLA study in rats and mice demonstrates that heart attacks occurring in the last trimester or late months of pregnancy result in worse heart function and more damaged heart tissue than heart attacks among non-pregnant females.

The research is published in the July edition of the peer-reviewed journal Basic Research in Cardiology. (more…)

Skin Patch Improves Attention Span in Stroke Patients

Researchers at the UCL Institute of Neurology have found that giving the drug rotigotine as a skin patch can improve inattention in some stroke patients.

Hemi-spatial neglect, a severe and common form of inattention that can be caused by brain damage following a stroke, is one of the most debilitating symptoms, frequently preventing patients from living independently. When the right side of the brain has suffered damage, the patient may have little awareness of their left-hand side and have poor memory of objects that they have seen, leaving them inattentive and forgetful. Currently there are few treatment options. (more…)
