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)

Eavesdropping fringe-lipped bats spread culture through sound
ike a diner ordering a dessert based solely on the "oohs" and "aahs" of a customer eating the same dish the next table over, frog-eating bats learn to eat new prey by eavesdropping on their neighbors as they eat, report biologists from The University of Texas at Austin.   view more (2006-06-20)

Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust.   view more (2006-06-07)

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... view more (2006-06-01)

Iraq's marshes show progress toward recovery
Reflooding of Iraq's destroyed Mesopotamian marshes since 2003 has resulted in a "remarkable rate of reestablishment" of native invertebrates, plants, fish, and birds, according to an article in the June issue of BioScience.   view more (2006-05-31)

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... 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... 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)

Stable polymer nanotubes may have a biotech future
Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely.   view more (2006-02-03)

Source of crucial immune cell in the skin discovered
Identification of precursor cell may lead to tumor immunotherapy as well as new treatment for rare disorder.   view more (2006-01-30)

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)

Newly Located Greek Temple to Be Discussed at AIA Annual Meeting
The discovery in Albania of a Greek temple dating back to the 6th century B.C. by researchers from UC's Classics Department will be publicly presented for the first time at the Archaeological Institute of America's annual meeting in early January.    view more (2006-01-09)

UI researchers discover star orbiting a 'medium-sized' black hole
University of Iowa researchers have found a star orbiting a "medium-sized" black hole - about 1,000 times more massive than the sun - in the nearby starburst galaxy M82, a development that may help explain how medium-sized black holes form and evolve.   view more (2006-01-06)

Regular didgeridoo playing reduces snoring and daytime sleepiness, finds a study published online by the BMJ today.   view more (2005-12-23)

Overfishing may drive endangered seabird to rely upon lower quality food
The effects of overfishing may have driven marbled murrelets, an endangered seabird found along the Pacific coast, to increasingly rely upon less nutritious food sources, according to a new study by biologists at the University of California, Berkeley.   view more (2005-12-20)

Key brain antioxidant linked to Alzheimer's and Parkinson's
A study conducted at the San Francisco VA Medical Center has identified a protein found in both mice and humans that appears to play a key role in protecting neurons from oxidative stress, a toxic process linked to neurodegenerative illnesses including Alzheimer's and Parkinson's diseases.   view more (2005-12-15)

Global warming could halt ocean circulation, with harmful results
Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of this occurring in this century.   view more (2005-12-08)

How do massive stars form?
Massive stars play a key role in the chemical and dynamical evolution of galaxies. The way massive stars form is still much debated among the astronomers' community: it is currently one of the hottest astrophysical topics.   view more (2005-11-09)
