Road to AC voltage standard leads to important junction
After 10 years of research, the National Institute of Standards and Technology (NIST) has unveiled the world's first precision instrument for directly measuring alternating current (AC) voltages.   view more (2006-07-24)

Possible Origin of Cosmic Rays Revealed with Gamma Rays
An international team of astronomers (including the UK) has produced the first ever image of an astronomical object using high energy gamma rays, helping to solve a 100 year old mystery - an origin of cosmic rays. Their research, published in the Journal Nature on November 4th, was carried out... view more (2004-11-02)

3D Sound Systems Using Groundbreaking Piezoelectric Springs
Piezoelectric materials such as quartz are used in digital watches and computers to produce stable vibrations at high frequencies. Polycrystaline ceramics, such as PZT (lead zirconate titanate), can be made to mimic the behaviour of these natural monocrystaline materials by polarising the crystals... view more (1999-11-29)

Dartmouth researchers discover chromium's hidden magnetic talents
Two Dartmouth researchers have determined that the element chromium displays electrical properties of magnets in surprising ways.   view more (2008-04-17)

UC Berkeley astronomers find magnetic Slinky in constellation of Orion
Astronomers announced today (Thursday, Jan. 12) what may be the first discovery of a helical magnetic field in interstellar space, coiled like a snake around a gas cloud in the constellation of Orion.   view more (2006-01-13)

Physicists create millimeter-sized 'Bohr atom'
Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved.   view more (2008-07-01)

Value of drugs for pre-osteoporosis exaggerated
A series of recent scientific publications have exaggerated the benefits and underplayed the harms of drugs to treat pre-osteoporosis or "osteopenia" potentially encouraging treatment in millions of low risk women, warn experts in this week's BMJ.   view more (2008-01-18)

Supernova remnant menagerie
The supernova remnant N 63A is a member of N 63, a star-forming region in the Large Magellanic Cloud (LMC). Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy.   view more (2005-06-07)

Reduced greenhouse gas emissions required to avoid dangerous increases in heat stress, researchers say
A study led by a Purdue University researcher projects a 200 percent to 500 percent increase in the number of dangerously hot days in the Mediterranean by the end of the 21st century if the current rate of greenhouse gas emissions continues. The study found France would be subjected to the largest... view more (2007-06-18)

Test identifies best candidates for implanted cardiac defibrillator, screens out those not helped
Last year, about 170,000 people in North America had devices surgically implanted to stop potentially fatal arrhythmias.   view more (2006-01-30)

Complex ocean behavior studied with 'artificial upwelling'
A team of scientists is studying the complex ocean upwelling process by mimicking nature - pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.   view more (2008-09-03)

EU Support for Two Projects Coordinated by DESY
The European Commission selected two projects coordinated by the DESY research center in Hamburg for support within its sixth Framework Programme. Among all the competitors for the much-coveted development funds, the projects "EUROFEL" and "EUROTeV" were ranked first and second,... view more (2004-08-04)

Genetic mutation found in peripheral artery disease
The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans.   view more (2008-02-22)
