Can Inflammation Predict Heart Disease and Stroke?

Groundbreaking research may be able to help predict how likely it is that a person will have heart disease or a stroke in the future. Studies have linked inflammation to the risk of cardiovascular disease because of the association between the release of C-Reactive Protein (CRP) and heart disease.

What is C-Reactive Protein (CRP)?

The National Institute of Health explains that CRP is a protein that is released when there is inflammation present in the body. The liver produces the protein and a blood test can be done to find out how much CRP is present in a person’s body.

What is inflammation?

John W. Kimball maintains a website describing in depth how inflammation develops in the body. Inflammation develops as a result of injury to the body. It can often be recognized by swelling and redness at the site of inflammation and may be accompanied by pain. Although inflammation often occurs on the surface of the skin, it can also occur internally. (more…)

Thawing Permafrost 50 Million Years Ago Led To Warm Global Events, Says New Study

A new study led by the University of Massachusetts Amherst and involving the University of Colorado Boulder proposes a simple new mechanism to explain the source of carbon that fed a series of extreme warming events on Earth about 50 million years ago called the Paleocene-Eocene Thermal Maximum, or PETM, as well as a sequence of similar, smaller warming events afterward.

“The standard hypothesis has been that the source of carbon was in the ocean in the form of frozen methane gas in ocean-floor sediments,” said lead study author Rob DeConto of the University of Massachusetts Amherst. “We are instead ascribing the carbon source to the continents in polar latitudes where permafrost can store massive amounts of carbon that can be released as CO2 when the permafrost thaws.” (more…)

U.S. Students Need New Way of Learning Science

EAST LANSING, Mich. — American students need a dramatically new approach to improve how they learn science, says a noted group of scientists and educators led by Michigan State University professor William Schmidt.

After six years of work, the group has proposed a solution. The 8+1 Science concept calls for a radical overhaul in K-12 schools that moves away from memorizing scientific facts and focuses on helping students understand eight fundamental science concepts. The “plus one” is the importance of inquiry, the practice of asking why things happen around us – and a fundamental part of science. (more…)

UCLA Study Identifies Genes Linked to Post-Traumatic Stress Disorder

Why do some people experience post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA study may shed light on the answer.

UCLA scientists have linked two genes involved in serotonin production to a higher risk of developing PTSD. Published in the April 3 online edition of the Journal of Affective Disorders, the findings suggest that susceptibility to PTSD is inherited, pointing to new ways of screening for and treating the disorder.

12-Mile-High Martian Dust Devil Caught in Act

A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14. It was imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. Despite its height, the plume is little more than three-quarters of a football field wide (70 yards, or 70 meters).

Dust devils occur on Earth as well as on Mars. They are spinning columns of air, made visible by the dust they pull off the ground. Unlike a tornado, a dust devil typically forms on a clear day when the ground is heated by the sun, warming the air just above the ground. As heated air near the surface rises quickly through a small pocket of cooler air above it, the air may begin to rotate, if conditions are just right. (more…)

An international research team is reporting the results of a research cruise they organized to study the amount, spread, and impacts of radiation released into the ocean from the tsunami-crippled reactors in Fukushima, Japan. The group of 17 researchers and technicians from eight institutions spent 15 days at sea in June 2011 studying ocean currents, and sampling water and marine organisms up to the edge of the exclusion zone around the reactors.

COLUMBIA, Mo. — Popular music videos have been criticized as having misogynistic messages and images. While more female music artists have gained visibility and created successful “brands” in recent years, critics argue that many of these artists are pushing the boundaries of acceptable norms with regard to race, gender and sexuality in popular culture.
