Giant Impact Near India -- Not Mexico -- May Have Doomed Dinosaurs
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. view more (2009-10-16)
Tracking tigers in 3-D
New software developed with help from the Wildlife Conservation Society will allow tiger researchers to rapidly identify individual animals by creating a three-dimensional model using photos taken by remote cameras. view more (2009-03-13)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. view more (2006-05-11)
Aggie physicists unite with Ivy League to develop anthrax detection method
Texas A&M University and Princeton University physicists have joined forces to perfect a powerful new weapon in the war on terrorism - a laser technique to identify deadly anthrax spores. Their results are published in the prestigious journal Science, due to hit newsstands tomorrow. view more (2007-04-13)
NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth. view more (2007-02-23)
New research detects human-induced climate change at a regional scale
Canadian and British climate scientists have clearly detected human-induced climate change at a regional scale in Canada, southern Europe and China. view more (2006-09-22)
Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
New Technology Identifies Warped Finger Prints at Warp Speed
Researchers at the University of Warwick have devised a means of identifying partial, distorted, scratched, smudged, or otherwise warped fingerprints in just a few seconds. view more (2007-10-02)
Identifying the metabolism of a healthy embryo could improve infertility treatment
Embryos that are most likely to result in a pregnancy are crucial to the success of in vitro fertilization (IVF) but are difficult to identify. Researchers at Yale School of Medicine, led by Emre Seli, M.D., are developing a fast, non-invasive test to help assess embryo viability for IVF. view more (2009-10-21)
Who are you? Mobile ID devices find out using NIST guidelines
A new publication that recommends best practices for the next generation of portable biometric acquisition devices-Mobile ID-has been published by the National Institute of Standards and Technology (NIST). view more (2009-08-27)
Detecting substances with swinging mirrors
As we know from the familiar sight of a rainbow, a spectrum always has a specific width between violet and red. As the spectrum fans out, in chemical analysis the light or radiation intensity must be measured at various points. One means to achieve this is by using a turning diffraction grid that works like a prism. The spectrum is then... view more... (2003-05-22)
Scientists describe new way to peer inside bacteria
As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria. view more (2005-08-30)
Up-and-coming researchers in life sciences
Fungal infections pose a serious threat to patients with weakened immune systems. In the past few years, candida albicans has become the most common germ for mycosis - and the number of cases is on the rise. This widespread member of the yeast family, has already developed strong resistance to antimycotic drugs commonly prescribed. Medication... view more... (2002-11-14)
Examination of radiation left from birth of universe could alter theories
Using relic radiation from the birth of the universe, astrophysicists at the University of Illinois have proposed a new way of measuring the fine-structure constant in the past, and comparing it with today. view more (2007-04-03)
Gold nanostars outshine the competition
Novel nanoparticles being tested at the National Institute of Standards and Technology (NIST) have researchers seeing stars. In a recent paper, NIST scientists used surface-enhanced Raman spectroscopy (SERS) to demonstrate that gold nanostars exhibit optical qualities that make them superior for chemical and biological sensing and imaging. view more (2008-10-16)
Ready to go: mobile terahertz devices
Terahertz waves, which until now have barely found their way out of the laboratory, could soon be in use as a versatile tool. Researchers have mobilized the transmitting and receiving devices so that they can be used anywhere with ease. view more (2008-04-09)
An efficient approach to monitor gastrointestinal microflora changes
Pi-deficiency in traditional Chinese medicine (TCM) is one of the most common digestive diseases and usually the equilibrium of gastrointestinal microflora are broken, which plays many important roles in the growth, development and performance of the host. view more (2009-05-22)
Knobbly kneed ID
Forget LED thumb-pad identification devices, complex retinal laser scanning, or even computerized iris recognition, the way forward for biometric validation is a quick X-ray snapshot of a person's knees, according to a report published in the International Journal of Biometrics. view more (2009-03-26)
Antarctic Ice Core milestone - 2002 m reached as year 2002 arrives
In the first weeks of the New Year a team of European scientists drilled successfully through 2002 metres of ice at Dome Concordia, high on East Antarctica`s plateau - one of the most hostile places on the planet. A specially created laboratory on the ice enabled scientists to analyse, for the first time, past climate shifts within hours of each 3... view more... (2002-01-15)
Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
