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)

A single gene makes the chicken a victim
Feather pecking is a common and serious behavioural disorder in laying hens around the world. The chickens peck and pull the feathers of their victims, and this may lead to cannibalism. Now a group of researchers under the lead of Per Jensen, Professor of ethology at Linköping University have... view more (2004-10-04)

Scientists ponder plant life on extrasolar Earthlike planets
When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared Vulcan, Spock, of Star Trek fame.   view more (2007-06-20)

New steroid test uses oil exploration technique
It's a technique that has previously been used for oil exploration - now researchers at The University of Nottingham have developed a new, highly sensitive, anti-doping steroid test using hydropyrolysis.   view more (2008-03-05)

Parasites a key to the decline of red colobus monkeys in forest fragments
Forest fragmentation threatens biodiversity, often causing declines or local extinctions in a majority of species while enhancing the prospects of a few.   view more (2007-10-25)

Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells.   view more (2008-01-16)

Climate change following collapse of the Maya empire
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease... view more (2002-01-29)

Ancient climate change may portend toasty future
Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon.   view more (2006-12-08)

Western images lead to changes in body shape in South Africa
Black South African women are becoming thinner because of the influence of the West, including media-portrayed images of waif-like women in films and TV shows according to new research. The findings come from a study between Northumbria University in the United Kingdom and the University of... view more (2004-04-14)

Awkward! New Study Examines our Gazes During Potentially Offensive Behavior
It's happened to all of us: While sitting at the conference table or at dinner party, a friend or colleague unleashes a questionable remark that could offend at least one person amongst the group.   view more (2008-03-06)

Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement.   view more (2007-12-06)

Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams.   view more (2006-12-12)

Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even... view more (2008-08-29)

Fossil wood gives vital clues to ancient climates
New research into a missing link in climatology shows that the Earth was not overcome by a greenhouse period when dinosaurs dominated, but experienced rapid fluctuations in temperature and sea level change that resulted in a balance of the global carbon cycle.   view more (2006-02-24)

Livermore researchers shed new light on the physical properties of carbon
A team based in Livermore has shed some new light on the phase diagram of carbon at high pressure and temperature.   view more (2006-01-25)

Detox cure for art treasure
Many museums and churches own pieces of art which were treated with toxic pesticides in the past. Between the 1940’s and 80’s, it was quite usual to protect wood against insects and microorganisms with PCP (pentachlorophenol), DDT and lindane. Though the adverse effect was only... view more (2002-09-09)

Boston College scientists stretch carbon nanotubes
Physicists at Boston College have for the first time shown that carbon nanotubes can be stretched at high temperature to nearly four times their original length, a finding that could have implications for future semiconductor design as well as in the development of new nanocomposites.   view more (2006-01-19)

High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy... view more (2004-09-22)

Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth.   view more (2008-06-03)

The black rat's role in spreading human plague in Madagascar
Human plague first hit the Madagascan coasts in 1898, then became established permanently in the Hautes Terres, the high central region of the island, during the 1920s. Over the following decade, there were thousands of victims. Subsequently it has become less prevalent, first thanks to mass... view more (2001-04-26)

Land won't soak up carbon indefinitely say top scientists
A paper to be published this week in the journal Nature provides a new global view of terrestrial carbon sources and sinks and warns that current sinks cannot be counted on to mop up carbon dioxide emissions indefinitely. The results have potential implications for the Kyoto Protocol negotiations... view more (2001-11-06)

Prehistoric global warming may have contributed to fossil preservation
Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved "mass kills" of wildlife, according to a University of Oregon study presented at the Geological Society of America's annual meeting.   view more (2005-10-13)

Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.   view more (2008-02-28)

Greenhouse gas/temperature feedback mechanism may raise warming beyond previous estimates
A team of European scientists reports that climate change estimates for the next century may have substantially underestimated the potential magnitude of global warming.   view more (2006-05-22)

Researchers help sort out the carbon nanotube problem
National Institute of Standards and Technology (NIST) and university researchers report a significant step toward sorting out the nanotube "problem"-the challenge of overcoming processing obstacles so that the remarkable properties of the tiny cylindrical structures can be exploited in... view more (2005-07-27)
