65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet. view more (2008-05-06)
Extinction threats grow as sea governance rules ignored
Those who rule the ocean waves are being named and shamed today for their role in failing to prevent the near extinction of the albatross. view more (2005-03-03)
Rotators for the Canaries Large Telescope
TEKNIKER has concluded the verification tests on the two Nasmyth rotators which they have designed and constructed for the Large Telescope on the Canary Islands and which, probably over this coming Autumn, will be incorporated at the Grantecan installation. The two Nasmyth rotators are two son large rotating pieces of almost four metres diameter... view more... (2003-06-30)
Research removes major obstacle from mass production of tiny circuits
As they eliminate tiny air bubbles that form when liquid droplets are molded into intricate circuits, a Princeton-led team is dissolving a sizable obstacle to the mass production of smaller, cheaper microchips. view more (2007-01-18)
Was male domination deadly for dinosaurs?
Dinosaurs suddenly died out because they gave birth to too many males as a result of climate change. This is the theory put forward by David Miller of medicine and Jonathen Summers of mechanical engineering at the University of Leeds. They believe that dinosaur populations died out because the sex of their offspring was determined by temperature.... view more... (2004-05-10)
VLT Observations Address the Age of the Universe
The stream of important scientific results from ESOs Very Large Telescope (VLT) at Paranal (Chile) is increasing. Astronomers have had access to the first of the four 8.2-m telescopes since April 1999 and research articles based on observations with this new powerful facility are beginning to appear in larger numbers. The work reported here is one... view more... (1999-12-17)
Einstein's relativity theory proven with the 'lead' of a pencil
Scientists at The University of Manchester have discovered a new way to test Einstein's theory of relativity using the 'lead' of a pencil. view more (2005-11-10)
Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan. view more (2007-09-25)
How much water does the ocean have?
The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. view more (2009-11-13)
Creatine in addition to exercise enhances strength in older adults
Lower muscle mass and an increase in body fat are common consequences of growing older. view more (2007-10-03)
History and timing of human impact on Lake Victoria, East Africa
Lake Victoria, the world's largest tropical lake, suffers from severe eutrophication and the probable extinction of up to half its 500+ species of endemic cichlid fishes. New sediment-core data show that increased algal production developed from the 1930s onwards, paralleling human population growth and agricultural activity in the surrounding... view more...

Connection between depression and osteoporosis shown by Hebrew University researchers
Depression can cause a loss of bone mass, leading to osteoporosis and fractures, say researchers at the Hebrew University of Jerusalem. view more (2006-10-31)
Common osteoporosis treatment may help men with prostate cancer suffering from bone loss
Men with prostate cancer who experience bone loss from cancer treatment could benefit from a weekly oral therapy commonly given to women with osteoporosis. view more (2006-02-27)
CDF precision measurement of W-boson mass suggests a lighter Higgs particle
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (January 8, 2007) the world's most precise measurement by a single experiment of the mass of the W boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. The new W-mass... view more... (2007-01-09)
Ancient diets of Australian birds point to big ecosystem changes
A shifting diet of two flightless birds inhabiting Australia tens of thousands of years ago is the best evidence yet that early humans may have altered the continent's interior with fire, changing it from a mosaic of trees, shrubs and grasses to the desert scrub evident today, according to a University of Colorado at Boulder-led team. view more (2005-07-07)
Pre-clinical study suggests how steroid can reverse post-traumatic stress
Researchers at UT Southwestern Medical Center, working with mice, have shown how the body's own natural stress hormone can help lastingly decrease the fearful response associated with reliving a traumatic memory. view more (2006-09-13)
Research identifies protein in mice that regulates bone formation
Osteoporosis, a disease characterized by a decrease in bone mass and density and which makes people more susceptible to bone fractures and deformities, afflicts some 10 million Americans over the age of 50. view more (2006-06-23)
What Makes The Scorpion`S Sting Deadly Poisonous?
Even the scorpion`s exterior warns that this is a dangerous animal. And it proves to be true, as nothing good comes out when small animals and even human beings meet with this arthropod species: its sting causes a sharp pain, some tropical scorpion`s sting is often fatal for the victim. The scientists from the Moscow Institute for Organoelement... view more... (2002-03-15)
Humans lend a hand to critically endangered waterbird
Human impact on one of the world's most threatened bird species can be beneficial rather than destructive - and could even save it from extinction - according to counterintuitive new findings by the University of East Anglia (UEA). view more (2009-07-27)
Risk factors for developing complications from sleep apnea surgery
Patients undergoing surgery to correct sleep apnea are more likely to have complications if their condition is severe, they have a high body mass index, they have other medical problems or they are undergoing certain other surgical procedures at the same time. view more (2006-10-17)
