Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. view more (2005-06-30)
Study questions assumptions about human sensitivity to biological motion
Humans may not be any more sensitive in detecting biological motion compared with nonbiological motion, concludes a study recently published in Journal of Vision, an online, free-access publication of the Association for Research in Vision and Ophthalmology (ARVO). view more (2007-10-18)
Prevention is better than cure
The Institute of Biology is calling on the International Community to strengthen the Biological and Toxins Weapons Convention. In a statement to be presented to the Fifth Review Conference of the Parties to the Biological and Toxins Weapons Convention (BTWC), the Institute warns that the current genomics revolution may be misused unless a... view more...

New method for dating art prints and early books borrows know-how from genetic science
A new and relatively simple method for discovering the date when centuries-old art prints and books were produced has been developed at Penn State. view more (2006-06-21)
Measurements may help show if constants are changing
Physicists at JILA have performed the first-ever precision measurements using ultracold molecules, in work that may help solve a long-standing scientific mystery-whether so-called constants of nature have changed since the dawn of the universe. view more (2006-05-01)
Biology could be the root of bother
Better understanding of the biological and cognitive bases of disruptive behaviour in children will help psychologists determine which types of treatments are most likely to be effective. view more (2005-03-21)
Bright lights, not-so-big pupils
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain. The report appears online this week in Nature. view more (2009-01-05)
Preventing mother-to-child HIV transmission in low-income countries
Can HIV transmission in pregnancy in low income settings be prevented with round the clock rapid testing in labor? view more (2008-05-06)
Molecules in glass houses
Trapping biological molecules such as proteins and enzymes or even whole cells in rigid structures make them easier to use for a whole range of industrial and medical applications. But combining fragile biological molecules with tough materials is difficult to do without damaging the molecules and destroying their biological activity. As well as... view more... (2001-08-01)
UNIVERSITY SPIDER MAN CHARTS REGION`S SPECIES
A University of Plymouth lecturer has helped to compile a two-volume atlas detailing the biology, habitat and conservation of over 600 species of British spider. Peter Smithers of the Department of Biological Sciences has spent the last 20 years gathering information in Devon and Cornwall as part of the nationwide project, which was initiated in... view more...

Physicists lead the field in solving matter mystery of the Big Bang
A University of Sussex-led team of scientists is ahead in the race to solve one of the biggest mysteries of our physical world: why the Universe contains matter. With the help of a new £2.3 million grant, the team is working on a project to make one of the most sensitive measurements ever of sub-atomic particles. The results, expected within... view more...

Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T cells. They have shown that this "rendez-vous",... view more... (2004-08-23)
Negative effects of caffeine are stronger on daytime sleep than on nocturnal sleep
A new study at the Université de Montréal has concluded that people drinking coffee to get through a night shift or a night of studying will strongly hurt their recovery sleep the next day. view more (2006-10-03)
NIST method improves reliability of GPS clocks
Widely used by the military, first responders, surveyors and even consumers, GPS is a navigation and positioning system consisting of ground-based monitors and a constellation of satellites that rely on atomic clocks. view more (2005-10-10)
New study finds that ramelteon shows potential for circadian phase shifting
Results from a new study to further explore the mechanistic action of ramelteon suggest it may have the ability to shift the biological circadian rhythm - one's natural 24-hour sleep-wake cycle - based on a study model designed to examine this potential. view more (2006-05-23)
Inactivity of proteins behind longer shelf life when freezing
Frozen biological material, for example food, can be kept for a long time without perishing. A study by researchers at the University of Gothenburg, Sweden, is close to providing answers as to why. view more (2009-03-03)
Human reproductive rates follow biological scaling rules
In nations with high per capita energy consumption, women have fewer children. This phenomenon is an unexpected consequence of the biological scaling relationship between metabolism and reproductive rate: larger species of mammals have higher metabolism but lower birth rates. In the April 2003 issue of Ecology Letters, Moses and Brown show that... view more... (2003-04-08)
Researchers move closer to switching nuclear isomer decay on and off
Livermore researchers have moved one step closer to being able to turn on and off the decay of a nuclear isomer. view more (2007-04-06)
Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means... view more... (2009-01-22)
Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience. view more (2006-12-04)
