First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. view more (2006-10-17)
A plan for reintroducing megafauna to North America
Dozens of megafauna (large animals over 100 pounds) - such as giant tortoises, horses, elephants, and cheetah - went extinct in North America13,000 years ago during the end of the Pleistocene. view more (2006-10-03)
Nasal plastic surgery improves airway function
Nasal plastic surgery appears to improve nasal airway function in patients with severe nasal obstructions. view more (2006-09-19)
Researchers appeal for new regulations to save coral reefs from live fish trade
Researchers are calling for tighter controls on the live reef fish trade, a growing threat to coral reefs, in letters to the international journal Science. view more (2006-08-07)
World Trade Center dust cuts lung function capability in rescue workers
New York City firemen and emergency personnel exposed to dust from the collapse of the World Trade Center buildings experienced a decrease in lung function capability equal to 12 years of age-related decline during the year following the 9/11 disaster. view more (2006-08-01)
Purdue creates new low-cost system to detect bacteria
Researchers at Purdue University have developed a new low-cost system that analyzes scattered laser light to quickly identify bacteria for applications in medicine, food processing and homeland security at one-tenth the cost of conventional technologies. view more (2006-07-28)
Worker ants store fat to share with colony members during times of need
In a fascinating new study from the September/October 2006 issue of Physiological and Biochemical Zoology, Daniel A. Hahn (University of Florida) explores the ability of ants to store excess fat and pass it to colony members through lipid-rich oral secretions or unfertilized eggs. view more (2006-07-27)
Robot-assisted, laparoscopic surgery for vaginal vault prolapse found to be effective
Mayo Clinic researchers have found that laparoscopic surgery assisted by a surgical robot to fix vaginal vault prolapse, a collapse of the vagina that can occur after a hysterectomy, is an effective option to the traditional, open surgical repair when measured at least a year after the surgery. view more (2006-07-24)
Rhesus monkeys in Nepal may provide new alternative for HIV/AIDS research
Scientists investigating the genetic makeup of rhesus macaque monkeys, a key species used in biomedical research, have found the rhesus in Nepal may provide a suitable alternative to alleviate a critical shortage of laboratory animals used in work to develop vaccines against diseases such as HIV/AIDS. view more (2006-06-01)
Algae's Protein "Tails" Create Motion — and Aid Munching
When single-celled organisms such as sperm crack their whip-like appendages called flagella, the beating sets them in motion. But in certain colonies of green algae, flagella also boost nutrient uptake, according to surprising new research. view more (2006-05-30)
Global warming may have damaged coral reefs forever
Global warming has had a more devastating effect on some of the world's finest coral reefs than previously assumed, suggests the first report to show the long-term impact of sea temperature rise on reef coral and fish communities. view more (2006-05-16)
XMM-Newton reveals the origin of elements in galaxy clusters
Deep observations of two X-ray bright clusters of galaxies with ESA's XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented accuracy. view more (2006-05-11)
XMM-Newton digs into the secrets of fossil galaxy clusters
Taking advantage of the high sensitivity of ESA's XMM-Newton and the sharp vision of NASA's Chandra X-Ray space observatories, astronomers have studied the behaviour of massive fossil galaxy clusters, trying to find out how they find the time to form- view more (2006-05-01)
Discovery points to more effective ways of regulating cell signalling
A discovery made at The Walter and Eliza Hall Institute provides new insights into enhancing the function of the protein SOCS3, which regulates the response of cells to external stimuli. view more (2006-04-21)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. view more (2006-03-22)
Wrinkled membranes create novel drug-delivery system
A University of Illinois scientist studying how membranes wrinkle has discovered a novel system for on-demand drug delivery. view more (2006-02-15)
Drug resistance may travel same path as quorum sensing
The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing. view more (2006-02-07)
Genetic study shows humans have pushed orangutans to the brink of extinction
A new study published in the open-access journal PLoS Biology shows strong genetic evidence of a catastrophic collapse in orangutan populations living in the fragmented forests of the Kinabatangan Wildlife Sanctuary in Sabah, Malaysia. view more (2006-01-24)
Scientists find black hole's 'point of no return'
Scientists have found new evidence that black holes are performing the disappearing acts for which they are known. view more (2006-01-11)
