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…)
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 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…)
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…)
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…)
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…)
PASADENA, Calif. — From fresh rover tracks to an impact crater blasted billions of years ago, a newly completed view from the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity shows the ruddy terrain around the outcrop where the long-lived explorer spent its most recent Martian winter.
This scene recorded from the mast-mounted color camera includes the rover’s own solar arrays and deck in the foreground, providing a sense of sitting on top of the rover and taking in the view. Its release this week coincides with two milestones: Opportunity completing its 3,000th Martian day on July 2, and NASA continuing past 15 years of robotic presence at Mars. Mars Pathfinder landed July 4, 1997. NASA’s Mars Global Surveyor orbiter reached the planet while Pathfinder was still active, and Global Surveyor overlapped the active missions of the Mars Odyssey orbiter and Opportunity, both still in service.
