A step nearer to understanding superconductivity
Transporting energy without any loss, travelling in magnetically levitated trains, carrying out medical imaging (MRI) with small-scale equipment: all these things could come true if we had superconducting materials that worked at room temperature. view more (2007-06-07)
Researchers peg magnetism as key driver of high-temperature superconductivity
When it comes to superconductivity, magnetic excitations may top good vibrations. view more (2006-07-06)
Altered sex hormone levels, higher body temp affects sleep quality in postmenopausal women
In an examination of potential relationships between objective sleep measures, nocturnal sex hormone levels, and the nocturnal course of body temperature of older postmenopausal women. view more (2007-12-03)
Bright idea illuminates LED standards
The lack of common measurement methods among light-emitting diode (LED) and lighting manufacturers has affected the commercialization of solid-state lighting products. view more (2008-11-26)
Marine fossils improve predictions of climate change
A study of the ancient Mediterranean Sea will help to produce more accurate predictions of climate change. A team led by Royal Holloway geologist Dr Michal Kucera will map sea-surface temperature of the Mediterranean over past millennia. The data will provide a new target to test the computer models on which our predictions of climate change are... view more... (2002-06-06)
Fish with temperature-dependent sex determination face global warming
In vertebrates with separate sexes, sex determination can be genotypic (GSD) or temperature-dependent (TSD). TSD is very common in reptiles, where the ambient temperature during sensitive periods of early development irreversibly determines whether an individual will be male or female. view more (2008-07-30)
Strain has major effect on high-temp superconductors
Just a little mechanical strain can cause a large drop in the maximum current carried by high-temperature superconductors, according to novel measurements carried out by the National Institute of Standards and Technology (NIST). view more (2007-02-16)
UGA researchers propose new hypothesis on the evolution of hot springs microorganisms
Since their discovery in the late 1970s, microorganisms known as archaea have fascinated scientists with their ability to thrive where no other life can — in conditions that are extremely hot, acidic or salty. view more (2006-06-06)
UC Davis researchers discover key to body's ability to detect subtle temperature changes
Scientists have long known the molecular mechanisms behind most of the body's sensing capabilities. Vision, for example, is made possible in part by rhodopsin, a pigment molecule that is extremely sensitive to light. view more (2007-02-26)
Taking the temperature of the no-fly zone
Flies, unlike humans, can't manipulate the temperature of their surroundings so they need to pick the best spot for flourishing. New Brandeis University research in this week's Nature reveals that they have internal thermosensors to help them. view more (2008-06-12)
Transition Metal Selenites (Mn, Co, Ni, Fe, Cu, Zn and Cd)
The work involved a multidisciplinary task, undertaking the study of phases of mineralogical and physico-chemical interest. Selenites were synthesised, given that they are a new field and likely to present original physical properties. view more (2005-09-30)
Venus comes to life at wavelengths invisible to human eyes
A pale yellow-green dot to the human eye, Earth's twin planet comes to life in the ultraviolet and the infrared. New images taken by instruments on board ESA's Venus Express provide insight into the turbulent atmosphere of our neighbouring planet. view more (2008-12-04)
Extreme machine simulates space conditions
Conditions in space are unlike anything we experience on Earth. Incredible extremes of temperature that can switch in an instant, startling vacuum conditions, not to mention radiation - it`s a tough life for a spacecraft. So it is essential to make sure they are prepared to withstand these conditions before they are launched into this wholly... view more... (2002-05-07)
Global warming will negatively impact tropical species
Global warming is likely to reduce the health of tropical species, scientists from UCLA and the University of Washington report May 6 in Proceedings of the National Academy of Sciences. view more (2008-05-06)
Warming trend may contribute to malaria's rise
Could global warming be contributing to the resurgence of malaria in the East African Highlands? view more (2006-03-22)
Wearing helmets affects performance
Wearing protective helmets during sports can affect performance, according to a new study from Northumbria University. Tests were carried out on a group of young male cricketers and researchers investigated the physical and mental demands during an intense batting practice over eight overs when wearing a standard non-vented safety helmet and when... view more...

Brainy genes, not brawn, key to success on mussel beach
It's hard being a mussel: you have to worry about hungry starfish and even hungrier humans, not to mention an environment that can change your body temperature 50 degrees Fahrenheit in just a few hours. view more (2008-10-10)
Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

Unexpected cooling effect in Saturn's upper atmosphere
UK researchers from University College London (UCL), along with colleagues from Boston University, have found that the hotter than expected temperature of Saturn's upper atmosphere - and that of the other giant planets - is not due to the same mechanism that heats the atmosphere around the Earth's Northern Lights. view more (2007-01-29)
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)
