Prehistoric fossil snake is largest on record
Scientists have recovered fossils from a 60-million-year-old South American snake whose length and weight might make today's anacondas seem like garter snakes. view more (2009-02-05)
Living Metals
Using synchrotron x-ray microbeams, a research team from the Max Planck Institute for Metals Research in Stuttgart and the ESRF has been able to observe for the first time that the microscopic structure of a crystalline material fluctuates in time. The results are published today in Science Express with the title: Scaling in the Time Domain:... view more... (2005-04-22)
Late-breaking results of clinical trial on therapeutic endovascular cooling reported at TCT 2008
Late-breaking results from the COOL RCN (COOLing to Prevent Radio Contrast Nephropathy in Patients Undergoing Diagnostic or Interventional Catheterization) Trial were presented during the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF). view more (2008-10-15)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
Study finds regular daily exercise does not increase total sleep time
According to a research abstract that will be presented on Monday, June 8 at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, days with increased activity were followed by nights with lower total sleep time (TST), while nights with lower TST were followed by increased activities during the next day. view more (2009-06-08)
Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science. view more (2006-12-08)
Finding superconductors that can take the heat
Superconductors are materials with no electrical resistance that are used to make strong magnets and must be kept extremely cold-otherwise, they lose their superconducting abilities. view more (2005-11-09)
Watching tumors melt away
All standard methods of removing tumors have side effects. Surgical excision under anesthetic leaves a wound - usually extending into adjacent healthy tissue. It also raises the risk of cancerous cells spreading via blood and lymph vessels. The X- or gamma-rays used in radiation therapy have to pass through healthy tissue to reach deeper-lying... view more... (2003-12-01)
Potential for noninvasive brain tumor treatment
Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter. view more (2009-06-17)
Georgia State researchers shed light on fat burning
Researchers at Georgia State University have found that fat cells give feedback to the brain in order to regulate fat burning much the same way a thermostat regulates temperature inside a house. view more (2009-02-06)
European heat waves double in length since 1880
The most accurate measures of European daily temperatures ever indicate that the length of heat waves on the continent has doubled and the frequency of extremely hot days has nearly tripled in the past century. view more (2007-08-06)
NIST team develops novel method for nanostructured polymer thin films
All researchers at the National Institute of Standards and Technology (NIST) wanted was a simple, quick method for making thin films of block copolymers or BCPs (chemically distinct polymers linked together) in order to have decent samples for taking measurements important to the microelectronics industry. view more (2007-09-17)
How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the climax of the last ice age 20.000 years ago. Now... view more... (1999-05-03)
Rooftop PV data for better energy prediction models
New generations of photovoltaic (PV) roofing products utilize designs that allow them to be integral parts of the roof, providing both electricity and shelter from the elements. view more (2006-06-28)
Ancient climate switch could signify sharp increase in today's global temperature
A paper published in today's Nature suggests that global warming could rapidly accelerate due to a positive feedback mechanism caused by water vapour or rainfall. The paper, which examines a period of rapid climate change 55 million years ago, during the Paleocene and Eocene, offers a clear indication of how gradual global warming can rapidly... view more...

Hurricanes and climate change: A sharper view
n a study published in the July 2008 issue of Geophysical Research Letters, Drs. David S. Nolan and Eric D. Rappin from the University of Miami's Rosenstiel School of Marine and Atmospheric Science describe a new method for evaluating the frequency of hurricane formation in present and future tropical climates. view more (2008-08-13)
Global warming threatens Australia's iconic kangaroos
As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic kangaroos. view more (2008-10-16)
Preservation of fresh-cut vegetables; a producer's and consumer's sake
In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the '80s in the UK. Their market is yearly increasing with 25% in West Europe. Packaging fresh-cut... view more... (2002-03-19)
What makes life go at the tropics?
What causes tropical life to thrive: temperature, or sunlight? The answer is not necessarily "both." According to a study published online this week in PNAS Early Edition, the explosion of species at the tropics has much more to do with warmth than with light. view more (2008-05-28)
Cooling Off Periods
Research by a team of Cambridge scientists has provided new clues about the first dramatic cooling of the Earth's climate 34 million years ago. The team, based at the University of Cambridge's Department of Earth Sciences said that ocean temperature drops were apparently not responsible for the rapid formation of ice in Antarctica. Carrie Lear,... view more... (2000-01-12)
