Smoke from cigarettes, cooking oil, wood, shift male cardiovascular system into overdrive

NEW ORLEANS (April 17, 2009) Secondhand tobacco smoke and smoke from cooking oil and wood smoke affected cardiovascular function of men and women who were exposed to small doses of the smoke for as little as 10 minutes, according to a study from the University of Kentucky. The study confirmed ...

A paradigm shift in immune response regulation

Over the past decade various pieces of the puzzle how signal transmission controls immunity have been coming together. Now, in Cell an international team reports a paradigm shift in the regulation of immune response. Their results show that interaction with a linear ubiquitin chain is crucial fo...

Host shift triggers cascading effect on ecosystem, research finds

Climate change causing significant shift in composition of coastal fish communities

NARRAGANSETT, R.I. June 27, 2008 A detailed analysis of data from nearly 50 years of weekly fish-trawl surveys in Narragansett Bay and adjacent Rhode Island Sound has revealed a long-term shift in species composition, which scientists attribute primarily to the effects of global warming. Ac...

Conservation strategies must shift with global environmental change, says CU-Boulder study

Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

The warming most global climate models predict will do more harm than simply raise the sea levels that most observers fear. It will make drastic changes in fragile ecosystems throughout the world, especially in the Antarctic. A warming trend during the last few decades in the Antarctic Peninsula...

DNA analysis reveals rapid population shift among Pleistocene cave bears

Studying DNA obtained from teeth of ancient cave bears, researchers have been able to identify a shift in a particular population of the bears inhabiting a European valley in the late Pleistocene era. The findings illustrate the ability of DNA sequence analysis to reveal aspects of animal populatio...

Pressured by predators, lizards see rapid shift in natural selection

Countering the widespread view of evolution as a process played out over the course of eons, evolutionary biologists have shown that natural selection can turn on a dime -- within months -- as a population's needs change. In a study of island lizards exposed to a new predator, the scientists found ...

Molecular research suggest shift needed in how some drugs are created

The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say.
