Possible brain hormone may unlock mystery of hibernation
The discovery of a possible hibernation hormone in the brain may unlock the mystery behind the dormant state, researchers reported in the April 7, 2006 issue of Cell. view more (2006-04-06)
Butterflies lose body fat during metamorphosis
A group of scientists from Oregon have discovered that butterflies experience a great loss in body fat during metamorphosis. view more (2006-03-21)
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)
Study shows hibernating bears conserve more muscle strength than humans on bed rest do
A fascinating new study from the May/June 2007 issue of Physiological and Biochemical Zoology quantifiably measures the loss of strength and endurance in black bears during long periods of hibernation. view more (2007-04-25)
Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. view more (2007-04-02)
Warming most evident at high latitudes, but greatest impact will be in tropics
The impact of global warming has become obvious in high latitude regions, including Alaska, Siberia and the Arctic, where melting ice and softening tundra are causing profound changes. view more (2005-08-15)
Hormone helps mice 'hibernate,' survive starvation
A key hormone enables starving mice to alter their metabolism and "hibernate" to conserve energy, revealing a novel molecular target for drugs to treat human obesity and metabolic disorders, UT Southwestern Medical Center researchers have found. view more (2007-06-06)
Dying bats in the Northeast remain a mystery
Investigations continue into the cause of a mysterious illness that has resulted in the deaths of thousands of bats since March 2008. At more than 25 caves and mines in the northeastern U.S, bats exhibiting a condition now referred to as "white-nosed syndrome" have been dying. view more (2008-05-09)
HHMI Undergraduate Researcher Turns Up the Heat on Hibernation
If doctors could put people in hibernation and pull them out at will, scientists think they could minimize damage from strokes, help recipients' bodies accept transplanted organs, perhaps even enable astronauts to travel in suspended animation until reaching distant destinations. view more (2006-02-01)
How Ground Squirrels Lose Weight
Spring. First flowers sprout from the ground, and animals wake up from hibernation (dormancy) and come out from their burrows. If not for the hibernation, small rodents would starve or freeze to death in winter. However, the winter slumber is not a kind of rest in a sanatorium. Animals become emaciated during winter, and all they think about in... view more... (2002-06-04)
Tagged turtles in the eye of the storm?
A NERC-funded researcher is tracking a number of migrating marine turtles which could be sent off-course or washed ashore by Hurricane Isabel. Updates on the turtles' progress can be followed on the web. Dr Brendan Godley and colleagues from the University of Exeter are using satellite technology to track the endangered green and loggerhead... view more... (2003-09-22)
Networking around the clock
A Brandeis University study published in Cell this week shows for the first time experimentally that the circadian cells in fruit flies function as a network that enables the insects to adapt their behavior according to seasonal changes. view more (2007-04-09)
Linking With The Future
Exploring and using space is the biggest adventure facing mankind. Finding innovative ways for ESA to continue doing this is the role of the Advanced Concepts Team (ACT) at ESA's European Space Technology Research Centre (ESTEC). It is their job to look into the future and identify ideas which could enable missions that currently sound like... view more... (2004-07-08)
Mate or hibernate? That's the question worm pheromones answer
If worms could talk, they might tell potential suitors, "I like the way you wriggle," complete with that telltale come slither look. view more (2008-07-25)
Vive the vole!
The gathering of data for research involving an animal usually involves invasive procedures or death for the experimental animals. But critical data may now be collected through a nonlethal procedure, according to a new paper for the forthcoming issue of Physiological and Biochemical Zoology. view more (2008-04-01)
A new and safer technique in heart surgery
The new technique of SELECTIVE CEREBRAL PERFUSION has been successfully applied for the first time in the Basque Autonomous Community (B.A.C.). Surgeons keep a patient in a state of hibernation at 15 degrees centigrade, without brain activity and with heart circulation and respiratory activity at a standstill for one hour while an aorta implant is... view more...

Artemis finally reaches operational orbit
ESA PR 07-2003. Artemis has finally reached geostationary orbit, some 36 000 km above the Earth, at 21.5°E. This announcement would, if all had gone to plan, been made just a few days after lift-off on 12 July 2001. Now, eighteen months and some serious brainstorming further on, the most advanced ESA telecommunications satellite ever... view more... (2003-01-31)
Whales Are More Precious Than Oil
WWF and the International Fund for Animal Welfare (IFAW) published results of scientific assessment of the "Sakhalin-2" oil and gas project's (Sakhalin Energy company) impact on the Okhotsk-Korean population of grey whales. The findings are distressing: if only three females perish, this grey whale (Eschrichtius robustus) population will... view more... (2005-03-14)
Eighteen Bear Cubs Leave For Adult Life
This year the brown bear population inhabiting the forests in the vicinity of the town of Tver has been increased by eighteen more bears. The bear population grows up annually thanks to the effort undertaken by Valentin Pazhetnov, Doctor of Biology, and his family. Since 1990 they have been returning back to the natural environment the bears... view more... (2002-09-23)
Environmentally-friendly pesticide to combat potato cyst nematodes
NWO researchers have produced a substance in the laboratory which wakens potato cyst nematodes (eelworms) from hibernation. Using this substance in a field of potatoes the eelworms came out of hibernation too early and died from starvation. These creatures cause serious damage to potato crops throughout the world. Potato cyst eelworms are... view more... (2001-10-08)
