Migraine mutations reveal clues to biological basis of disorder
Fifteen percent to 20 percent of people worldwide suffer from migraines - excruciating headaches often presaged by dramatic sensations, or "auras." By studying a rare, inherited form of migraine, researchers at Vanderbilt University Medical Center have found clues to the biological basis of the painful, debilitating disorder. view more (2008-07-01)
Experimental atomic clock uses ytterbium 'pancakes'
Scientists at the National Institute of Standards and Technology (NIST) working with Russian colleagues have significantly improved the design of optical atomic clocks that hold thousands of atoms in a lattice made of intersecting laser beams. view more (2006-03-07)
Physicists offer new approach to studying antimatter
What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? view more (2005-11-01)
Laser trapping of erbium may lead to novel devices
Physicists at the National Institute of Standards and Technology (NIST) have used lasers to cool and trap erbium atoms, a "rare earth" heavy metal with unusual optical, electronic and magnetic properties. view more (2006-05-01)
New Transparent Insulating Film Could Enable Energy-Efficient Displays
Johns Hopkins materials scientists have found a new use for a chemical compound that has traditionally been viewed as an electrical conductor, a substance that allows electricity to flow through it. view more (2009-11-10)
System that regulates blood pressure is amiss in some healthy, young blacks
When stress increases blood pressure, a natural mechanism designed to bring it down by excreting more salt in the urine doesn't work well in about one-third of healthy, black adolescents, researchers report. view more (2009-05-11)
NIST atom interferometry displays new quantum tricks
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with light while also making the atoms do things that light just won't do. view more (2007-05-29)
Protein simulation can be done three times as fast
Protein movement can be simulated three times as fast than had been thought possible up to now. Researchers from Groningen achieved the gain in speed by leaving out the calculations concerning hydrogen atoms. Meanwhile research groups around the world are adapting their simulation programs. view more (2002-06-24)
Sussex scientist becomes Fellow of the Royal Society
A University of Sussex chemistry professor has been elected a Fellow of the Royal Society (FRS), the premier honour for British and Commonwealth scientists. The Royal Society – the UK’s national academy for science – announced yesterday that Professor Tony Stace, from Lewes, is one of 42 new Fellows. view more (2002-05-14)
Caught in Flight
Chemists are very interested in unusual molecules that are made from atoms of a single element. For example, fullerenes ("buckyballs") and nanotubes, made of pure carbon, are generating a lot of excitement among materials scientists. If all were as it should be, the element phosphorus should be more similar to carbon than any other member of the... view more... (1999-11-24)
Simply weird stuff: Making supersolids with ultracold gas atoms
Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have proposed a recipe for turning ultracold "boson" atoms-the ingredients of Bose-Einstein condensates-into a "supersolid," an exotic state of matter that behaves simultaneously as a solid... view more...

Laser tweezers sort atoms
Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up. view more (2006-07-13)
Beyond the bonds that bind: UCSB researchers discover hydrogen can form multicenter bonds
Researchers at the University of California, Santa Barbara have shown that, under the right circumstances, hydrogen can form multicenter bonds, where one hydrogen atom simultaneously bonds to as many as four or six other atoms. view more (2006-12-04)
Cambridge led team discovers gene mutation which prevents carriers from feeling pain
Researchers have discovered a gene mutation which prevents the otherwise healthy carriers from sensing pain, after studying three related families with a rare genetic disorder in northern Pakistan. view more (2006-12-14)
Betaine relieves dry mouth symptoms
In the present study, betaine protected oral mucosa and skin against irritation caused by foaming substances in toothpastes, and relieved subjective symptoms of dry mouth. The feeling of dry mouth was eased after the use of betaine containing, detergent-free toothpaste in half of the subjects who had persistent subjective symptoms of dry mouth.... view more...

University of Oklahoma Researchers Discover Giant Rydberg Atom Molecules
A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. view more (2009-06-25)
Stopping atoms
With atoms and molecules in a gas moving at thousands of kilometres per hour, physicists have long sought a way to slow them down to a few kilometres per hour to trap them. view more (2007-10-03)
NIST physicists turn to radio dial for finer atomic matchmaking
Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute of the National Institute of Standards and Technology (NIST) and the University of Maryland and their collaborators have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening... view more...

Scientists provide new evidence for cellular cause of SIDS
University of Chicago researchers and colleagues have found strong support that a disturbance of a specific neurochemical can lead to sudden infant death syndrome, the primary cause of death before age 1 in the United States. view more (2006-03-08)
NIST atomic fountain clock gets much better with time
The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, physicists at the National Institute of Standards and Technology (NIST) report. view more (2005-09-26)
