Extraordinary life found around deep-sea gas seeps
An international team led by scientists from the United States and New Zealand have observed, for the first time, the bizarre deep-sea communities living around methane seeps off New Zealand's east coast.   view more (2006-11-21)

The Milky Way shaped life on Earth
Frenzied star-making in the Milky Way Galaxy starting about 2400 million years ago had extraordinary effects on life on Earth.   view more (2006-11-15)

Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist.   view more (2006-11-15)

Antibody reduces incidence of acute rejection in high-risk kidney transplant patients
Nearly 70 percent of kidney transplant patients get short-term drug therapy initially administered during surgery to help prevent rejection.   view more (2006-11-09)

Life in the extreme
Cold seeps are deep-sea environments, usually a few square meters in size, where fluid is released through slow diffusion from the sea floor. Mud volcanoes which are active areas of fluid seepage, are other extreme environments discovered in the 1990s. These harsh conditions give rise to some of the most extreme and scientifically challenging... view more... (2006-11-09)

Happiness and other positive emotions play an even more important role in health than previously thought.   view more (2006-11-08)

Regular, moderate exercise reduces the risk of colds in postmenopausal women
Postmenopausal women who want to decrease their risk of colds would be well advised to dust off their sneakers and get moving, suggests a new study led by researchers at Fred Hutchinson Cancer Research Center.   view more (2006-10-26)

New study indicates moderate exercise may protect against colds
A moderate exercise program may reduce the incidence of colds. A study published in the November issue of The American Journal of Medicine, led by researchers at Fred Hutchinson Cancer Research Center, found that otherwise sedentary women who engaged in moderate exercise had fewer colds over a one year period than a control group.   view more (2006-10-26)

Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean.   view more (2006-10-05)

New study explains why hotter is better for insects
Organisms have been able to adapt to environments ranging from cold polar oceans to hot thermal vents. However, University of Washington researchers have discovered a limit to the powerful forces of natural selection, at least when it comes to the adaptation of insects to cold temperatures.   view more (2006-10-03)

Bacteria discovery aids food production, water purification
The search for a type of bacteria that creates better ice cream and artificial snow has suddenly become a lot easier, thanks to a discovery by Queen's University biologist Virginia Walker.   view more (2006-10-02)

Study shows how herpes infects cornea, evades immune cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine.   view more (2006-09-26)

Live H5N1 avian flu virus vaccines show protection in animal studies
When tested in mice and ferrets, experimental vaccines based on live, weakened versions of different strains of the H5N1 avian influenza virus were well-tolerated and protected the animals from a deadly infection with naturally occurring H5N1 flu viruses.   view more (2006-09-13)

Cold Spring Harbor Protocols features methods for analyzing protein interactions
Cold Spring Harbor Protocols, an online journal that publishes methods used in a wide range of biology laboratories, has added over 40 new peer-reviewed protocols to its archive today.   view more (2006-09-11)

Low vitamin E intake during pregnancy can lead to childhood asthma
Children whose mothers had a low intake of vitamin E during pregnancy are more likely to develop wheezing and asthma by age five.   view more (2006-09-01)

Why piglets shudder to keep warm
Piglets are sensitive to cold and shiver to maintain their body heat. Researchers at Uppsala University have uncovered a genetic reason why these newborns are less tolerant of the cold than other newborn mammals.   view more (2006-08-21)

Breaks in hibernation help fight bugs
A habit in some animals to periodically wake up while hibernating may be an evolutionary mechanism to fight bacterial infection, according to researchers at Penn State.   view more (2006-08-17)

New method shows that neocortical nerve cells are not renewed
Most bodily organs continually die and regrow a little at a time. It takes two years, for example, for all the cells of the liver to be replaced by fresh ones. Research from Karolinska Institutet in Sweden now shows that there is one important exception to this - the nerve cells of the brain remain the same throughout a person's life.   view more (2006-08-14)

Current technology for brain cooling unlikely to help trauma patients
Attempts to cool the brain to reduce injury from stroke and other head trauma may face a significant obstacle: current cooling devices can't penetrate very deeply into the brain.   view more (2006-08-07)

More efficient and ecological system for the production of electricity, cold and heat
IK4 is taking part in a European project the aim of which is to design a single installation that will, at the same time, produce electricity, cold and heat for domestic use, while affording a notable reduction in environmental impact.   view more (2006-07-31)
