Cystic fibrosis patients may breathe easier, thanks to bioengineered antimicrobials
By better understanding how antimicrobials bind and thereby get inactivated in the mucus of air passages, researchers at the University of Illinois may have found a way to help cystic fibrosis patients fight off deadly infections.   view more (2007-09-25)

Researchers locate mantle's spin transition zone, leading to clues about Earth's structure
Researchers have located the spin transition zone of iron in Earth's lower mantle, a discovery which has profound geophysical implications.   view more (2007-09-24)

Orphan stars found in long galaxy tail
Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought.   view more (2007-09-21)

Molecules of positronium observed in the laboratory for the first time
Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their antiparticles, called positrons.   view more (2007-09-13)

Implantable device designed to detect, stop seizures under study at MCG
A small device implanted in the skull that detects oncoming seizures, then delivers a brief electrical stimulus to the brain to stop them is under study at the Medical College of Georgia.   view more (2007-09-11)

Promising Drug Combination May Help Those with Ocular Melanoma that has Spread
A combination of two drugs shows promise in treating a rare and therapy-resistant type of melanoma that originates in the eye and spreads to other organs, according to a new study led by Duke University Comprehensive Cancer Center researchers.   view more (2007-09-05)

Rovers begin new observations on changing Martian atmosphere
Mars rover scientists have launched a new long-term study on the Martian atmosphere with the Alpha Particle X-ray Spectrometer, an instrument that was originally developed at the University of Chicago.   view more (2007-08-30)

Gamma globulin effective in treating eye infections caused by adenoviruses
Gamma globulin, a type of antibody isolated from blood samples that used to be routinely given to health care workers and international travelers to protect them from infectious diseases, is a highly effective treatment for pinkeye with little apparent toxicity, according to a study by researchers... view more (2007-08-29)

Neutron stars warp space-time, U-M astronomers observe
Einstein's predicted distortion of space-time occurs around neutron stars, University of Michigan astronomers and others have observed.   view more (2007-08-29)

Safe water: simpler method for analyzing radium in water samples cuts testing time
A simpler technique for testing public drinking water samples for the presence of the radioactive element radium can dramatically reduce the amount of time required to conduct the sampling required by federal regulations. The U.S. Environmental Protection Agency (EPA) has approved use of the new... view more (2007-08-29)

Astronomers Pioneer New Method For Probing Exotic Matter
Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properties of these ultradense objects.   view more (2007-08-28)

XMM-Newton and Suzaku help pioneer method for probing exotic matter
Astronomers using XMM-Newton and Suzaku have seen Einstein's predicted distortion of space-time and pioneered a ground-breaking technique for determining the properties of neutron stars.   view more (2007-08-28)

Toxic shock: immune system's anthrax link
Human immune proteins crucial for fighting cancer, viruses and bacterial infections belong to an ancient and lethal toxin family previously only found in bacteria, Australian researchers have found.   view more (2007-08-24)

Possible closest neutron star to Earth found
Using NASA's Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth -- and possibly the closest.   view more (2007-08-21)

Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned
Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed.   view more (2007-08-17)

Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters.   view more (2007-08-17)

A "Broader" Look at Cardiac CTA Images Often Finds Diseases/Disorders Beyond the Heart
Performing cardiac CTA after coronary artery bypass surgery (CABG) can reveal unsuspected and potentially significant findings beyond the heart.   view more (2007-08-14)

MIT creates 3-D images of living cell
A new imaging technique developed at MIT has allowed scientists to create the first 3D images of a living cell, using a method similar to the X-ray CT scans doctors use to see inside the body.   view more (2007-08-13)

FSU physicist takes a trip to nuclear 'island of inversion'
Far from the everyday world occupied by such common elements such as gold and lead lies a little-understood realm inhabited by radioactive, or unstable, elements.   view more (2007-08-10)

Researchers rely on Newton's interference for new experiment
Most people think of Sir Isaac Newton as the father of gravity. But for Lawrence Livermore National Laboratory physicist Henry Chapman and his colleagues, Newton's "dusty mirror" experiment served as a launching pad for them to keenly watch the X-ray induced explosion of microscopic... view more (2007-08-09)

Teamwork between 2 key proteins necessary for normal development and regulation of red blood cells
Virginia Commonwealth University researchers studying hemoglobin genes, mutations of which play a role in genetic blood disorders like sickle cell anemia and beta-thalassemia, have identified two proteins that are responsible for regulating overlapping groups of genes during the development of red... view more (2007-08-07)

Where Broken DNA is Repaired
Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer.   view more (2007-08-03)

Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs.   view more (2007-08-01)

Toxic milk
In the August 1 issue of G&D, Dr. Ronald Evans (Salk Institute) and colleagues report on their discovery that mutations in the mouse gene encoding PPARγ adversely affect lactation milk quality, and have serious health consequences for nursing pups.   view more (2007-07-24)

New tool to measure speeding nuclei is a fast-beam first
