Good news: As you age, leg blood vessels adapt so you can still exercise without fainting

... -- can create a "heady" feeling, which reflects a temporary drop in blood pressure. This stimulates sympathetic nerves throughout the body to release substances that constrict blood vessels, even those vessels that feed working muscles. Blood vessels in our leg muscles must respond to both dilating and ...

World's top theoretical physicists converge to consider 'future of physics'

...ted by many a visitor who bikes in from his or her temporary abode in the vicinity of the campus. To recur to the "E" footprint, the part of the new addition with the auditorium is positioned to close the "E," but the rest extends out towards the ocean beyond the top horizontal of the "E," not in the ...

...ly, they must subjectively judge the rate at which temporary bone (the "callus") is replaced with permanent bone. Also, they look for increased stiffness at the fracture site, which may provide another sign of healing. Sabina Gheduzzi of the Unversity of Bristol ( S.Gheduzzi@bristol.ac.uk ) and her colleagu...

Scientists find acid rain an unlikely ally in the battle against a greenhouse gas

... become warmer. In this way, acid rain acts like a temporary lid on the largest methane source. Gauci is cautious about the image presented by acid rain. "We wouldn't want to give the impression that acid rain is a good thing - it has long been known that acid rain damages natural e...

NSF funds Panikov's Alaskan Tundra Microbial Observatory project

In 1990-96, when environmental scientists started intensive year-round recording of gas emission from soils to atmosphere, they found sizeable winter activity of the tundra microbial co...

Violent ocean motion no magic potion for reefs

...ever, and could even be exacerbated by the storms' temporary removal. Further south, off areas beyond the brunt of the storms, the team has found alarming concentrations of a cyanobacterium similar to algae killing corals and other reef organisms. "This is uncharted territory," says Harbor Branch marine ecolog...

Sardines may prevent toxic gas eruptions off the California and African coasts

...e of sardine abundance coincided with a noticeable temporary hiatus in eruption frequency off Namibia in 2002." Bakun and Weeks also warn that the areas around Cape Mendocino, California, and Cape Sim, Morocco, may be dangerously close to the "tipping point," possibly ripe for phytoplankton population explosi...

Sinking coastlines may precede large subduction zone quakes

...posited by a tsunami. Subsidence is indicated by a temporary change in the types of microscopic organisms with shells specifically foraminifera and thecamoebians in the mud, as the formerly freshwater marshes sink and become brackish or saltwater marshes. One marsh in Alaska apparently sank about half a foot...

Grizzlies set to invade high Arctic?

... Island home. Near a cabin used by researchers for temporary stop-overs, they found grizzly bear paw prints in the mud. And from the cabin's outside walls and a guy wire attached to the roof they collected two intriguing brown hairs. These were sent for analysis to Wildlife Genetics International Inc. in Nelso...

Cure no quick fix for cancer survivors on long road to recovery

Their work is disrupted, and they frequently face financial challenges and high health-care costs. "All of this occurs in the setting of a considerable amount of anxiety about whether the transplant is...

Tiny scaffolding allows stem cells to become working fat cells

Along with Xihai Kang and Yubing Xie, both postdoctoral fellows in his laboratory, Kniss built a fabric-like carpet of polyethylene terephathalene (PET), or Dacron, f...

Statins, other cholesterol depletors, may disrupt hypertension development: UCSD study

Lovostatin, MBCD significantly reduce calcium entry, cut cell proliferation In their research, the team saw that "smooth muscle cells isolated from pulm...

New technology, new approach to help heart and lung patients awaiting transplants

... Medicine, Baltimore. Griffith explains that good temporary options have been available for some time, but they are bulky and restrictive for patients. He says there is an urgent need for a better assistive device, and ultimately, a mechanical replacement for failing lungs. An interventional lung assist (ILA)...

Buying time through 'hibernation on demand'

...ramatically an organism's need for oxygen. If such temporary metabolic inactivity and subsequent freedom from oxygen dependence could be replicated in humans, it could help buy time for critically ill patients on organ-transplant lists and in operating rooms, ERs and battlefields, Roth said. "Manipulating t...

Gene keeps neural cells on correct developmental path

... The new study reports that REST uses a different temporary off mechanism to direct neuronal development. "This study shows that there is more than one way to keep a REST-regulated gene repressed," said Michael G. Rosenfeld, an HHMI investigator at University of California, San Diego, who co-authored an accom...

Dinosaur fossil bone leads to gender, age determinations

...iggered by an increase in estrogen levels, and the temporary tissue provides the calcium necessary to form eggshells. Medullary bone is only found in present-day female birds; no other egg-laying species including crocodiles, the other living dinosaur relative produces this tissue naturally. Because the din...

Positive effects of nuclear medicine, 'smart drugs' provide hope for non-hodgkin's lymphoma patients

...atients find that the most common side effect is a temporary lowering of blood counts for several weeks. Patients are now offered a choice of "months of chemotherapy or a tracer and treatment dose given over about a week," said Wahl. Results are even more promising using tositumomab and iodine-131 tositumomab ...

Researchers merge spatial and temporal structure within a metapopulation model

A consequence of ongoing degradation is that more and more species are being challenged to survive as spatially structured populations w...
