The kapok connection -- Study explains rainforest similarities

06-15-2007 · EurekAlert!

Celebrated in Buddhist temples and cultivated for its wood and cottony fibers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago.

Study explains why patients with OSA are at higher risk for cardiovascular disease
06-01-2007 · EurekAlert!
Researchers have found that patients with obstructive sleep apnea have higher levels of a type of dead cells (apoptotic cells) from the lining (endothelium) of their blood vessels circulating in their bloodstream than people who do not have OSA. The finding may help explain why those with OSA are at higher risk for cardiovascular disease.

UVA researchers explain cell response to skin-damaging UV rays
10-01-2007 · EurekAlert!
Researchers at the University of Virginia Health System have published a new study that helps scientists around the world expand the body of knowledge on how cells protect themselves (or not) from DNA damage caused by UV rays. Their study reveals part of a 'simple switch' mechanism inside cells, triggered by UV exposure from the sun, that helps our cells survive and thrive after being exposed. This mechanism involves an unanticipated connection between several proteins in the cell, the researchers discovered.

A study proposes a new universal rule to explain the equilibrium of plant populations
09-18-2007 · EurekAlert!
A study financed by the BBVA Foundation and conducted by scientists Carlos Duarte, Nuria Agustì and Nuria Marbà from the Mediterranean Institute for Advanced Studies (CSIC - University of the Balearic Islands) has allowed the first-time formulation of a universal rule that explains the equilibrium of plant communities, showing how plants assure the survival of their species whether their lives last a day or are prolonged over centuries.

Why would Cheerios sponsor a NASCAR race?
10-18-2006 · EurekAlert!
Why would brands like Sue Bee honey and Cheerios cereal sponsor a NASCAR race? While most people can quickly see the relationship between a sponsor that makes tires or motor oil, not all corporate sponsors "fit" NASCAR in such an obvious way. In the first study to research the benefits of event sponsorship for brands that don't seem to fit with a particular event, researchers from the University of Queensland (Australia) reveal a relatively easy way for marketers to overcome a tenuous connection.

Study finds role of mid-brain in integrating heart and respiratory response to exercise
04-29-2007 · EurekAlert!
Oxford University researchers recently examined several deep brain nuclei during exercise and have concluded that the periaqueductal grey area (PAG), the small-celled gray matter adjoining or surrounding the cerebral aqueduct and the third ventricle in the midbrain, contains the greatest number of neural changes in connection with anticipation of exercise. The findings provide direct evidence implicating the PAG as a key area of the brain's circuitry's affecting cardiorespiratory response to exercise.

New study suggests Concord grape juice may provide protection against breast cancer
08-09-2007 · EurekAlert!
According to a new study, published in the current issue of the Journal of Medicinal Foods, natural compounds in Concord grape juice protected healthy human breast cells from DNA damage. Healthy human breast cells were exposed in a test tube to an environmental carcinogen, benzo(a)pyrene, that is able to initiate a chain of events leading to breast cancer. However, the introduction of Concord grape juice compounds blocked the connection of the carcinogen to the DNA of the healthy cells.

Research suggests new treatment approaches for glaucoma
12-05-2006 · EurekAlert!
New research from Children's Hospital Boston and the Massachusetts Eye and Ear Infirmary may help explain how glaucoma causes blindness, revealing the chain of events that ultimately damage the optic nerve, preventing visual information from getting to the brain. The study indicates possible targets for intervention, including one for which there are already approved drugs.

How eating less might make you live longer
03-05-2007 · EurekAlert!
Caloric restriction in non-obese people translates into less oxidative damage in muscle cells, according to a new study by Anthony Civitarese, Eric Ravussin and colleagues (Pennington Biomedical Research Center). As oxidative damage has been linked to aging, this could explain how limiting calorie intake without malnutrition extends life span.

Great expectations -- Study looks at why placebo effect varies from person to person
07-18-2007 · EurekAlert!
Why do some people experience a "placebo effect" from a sham treatment they believe to be real -- while other people don't respond at all" A new study may help explain why. Using two different types of brain scans, researchers have found that the extent to which a person responds to a placebo is closely linked to how active a certain area of their brain becomes when they're anticipating something beneficial.
