Supercontinuum generation and soliton dynamics milestone achieved
A research team led by Fetah Benabid, University of Bath, has observed for the first time the simultaneous emission of two resonant dispersive waves by optical solitons (waves that maintain their shape while traveling at constant speeds).   view more (2008-11-21)

Giant simulation could solve mystery of 'dark matter'
The search for a mysterious substance which makes up most of the Universe could soon be at an end, according to new research.   view more (2008-11-06)

First detection of magnetic field in distant galaxy produces a surprise
Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago.   view more (2008-10-02)

Scientists Detect Cosmic 'Dark Flow' Across Billions of Light Years
Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of matter that lies beyond the observable universe.   view more (2008-09-24)

New approach to treating cystic fibrosis lung infection shows promise
Researchers at the University of Calgary have found a new method of fighting severe lung infections in people with cystic fibrosis (CF). These findings are published in Proceedings of the National Academy of Science USA, this week.    view more (2008-09-23)

Individuals vary their immune response according to age, sex and the costs
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs?   view more (2008-09-11)

Old before their time? Aging in flies under natural vs. laboratory conditions
Evolutionary studies of aging typically utilize small, short-lived animals (insects, worms, mice) under benign conditions - constant temperature and humidity, no parasites, superabundant food - in the laboratory. Oddly enough, very little is known about aging in such animals in their harsh,... view more (2008-09-08)

Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.   view more (2008-08-07)

Alcohol consumption declining, according to results of new study
Overall alcohol use-particularly consumption of beer-is declining in the US, according to a new study published in the August 2008 issue of The American Journal of Medicine.   view more (2008-08-06)

Research exposes new target for malaria drugs
The malaria parasite has waged a successful guerrilla war against the human immune system for eons, but a study in this week's Journal of Biological Chemistry has exposed one of the tricks malaria uses to hide from the immune proteins, which may aid in future drug development.    view more (2008-08-05)

UT Pathologists Believe They Have Pinpointed Achilles Heel of HIV
Human Immunodeficiency Virus (HIV) researchers at The University of Texas Medical School at Houston believe they have uncovered the Achilles heel in the armor of the virus that continues to kill millions.   view more (2008-07-16)

NIST's Novel 'Noise Thermometry' May Help Redefine International Unit of Temperature
After seven years of work, researchers at the National Institute of Standards and Technology (NIST) have built a system that relies on the "noise" of jiggling electrons as a basis for measuring temperatures with extreme precision.   view more (2008-06-04)

Too hot to handle! Scientists identify heat sensing regulator
Neuroscientists at Johns Hopkins are a step closer to understanding pain sensitivity - specifically why it's variable instead of constant - having identified a gene that regulates a heat-activated molecular sensor.   view more (2008-05-14)

New technique determines that the number of fat cells remains constant in all body types
The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to... view more (2008-05-12)

Phase of clock gene expression in human leukocytes correlates with habitual sleep timing
The phase of clock gene expression in leukocytes, assessed in the absence of the masking effects of light-dark and sleep-wake cycles, correlates with habitual sleep timing, according to a study published in the May 1 issue of the journal SLEEP.   view more (2008-05-01)

Naval Research Laboratory to design lunar telescope to see into the dark ages
A team of scientists and engineers led by the Naval Research Laboratory (NRL) will study how to design a telescope on the Moon for peering into the last unexplored epoch in the Universe's history.   view more (2008-03-12)

Researcher investigates new developments in laser and sensor technology
Scientists hope that research being conducted in Binghamton University's Department of Physics, Applied Physics and Astronomy will create lasers that work at wavelengths currently inaccessible.   view more (2008-02-22)

NICE guidelines on breast cancer follow-up need urgent revision
The NICE guidelines on follow-up for breast cancer patients need urgent revision, warn experts in this week's BMJ.   view more (2008-01-18)

Hubble finds double Einstein ring
The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a... view more (2008-01-11)

CU-Boulder supercomputer simulation of universe may help in search for missing matter
Much of the gaseous mass of the universe is bound up in a tangled web of cosmic filaments that stretch for hundreds of millions of light-years, according to a new supercomputer study by a team led by the University of Colorado at Boulder.   view more (2007-12-07)

UT Southwestern urologist uses Botox to treat debilitating condition
Eight years ago, Lynette Kunz suffered a severe spinal cord injury that left her a quadriplegic and sufferer of involuntary bladder contractions. The condition constantly interfered with her daily life.   view more (2007-12-05)

Scientists solve cosmological puzzle
Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are born - one that has been largely ignored by the current model of how the universe evolved.   view more (2007-11-30)

Dark energy -- 10 years on
Three quarters of our universe is made up of some weird, gravitationally repulsive substance that was only discovered ten years ago - dark energy.   view more (2007-11-30)

Effects of progesterone on Alzheimer's disease
The first study on progesterone and Alzheimer's disease has found no clear preventive benefit for the widely prescribed hormone in an animal model.   view more (2007-11-28)

Texas A&M researchers examine Einstein's theories on the universe
Einstein's self-proclaimed "biggest blunder" - his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) - may not be such a blunder after all, according to the research of an international team of scientists that includes two Texas... view more (2007-11-28)
