The swirl of malleable rock in the earth’s mantle – located between the earth’s crust and core – may have greater effect on the earth’s surface than was once believed, a Purdue research team reports.

Using computer technology to create three-dimensional models of the earth’s mantle, Purdue’s Scott King has found evidence that some dramatic features of the earth’s surface could be the result of relatively rapid shifts in the direction in which crustal plat

A newly recommended treatment for latent tuberculosis (TB) infection can cause liver injury, and therefore needs to be used with great caution and frequent monitoring, according to a UCSF-led, multi-center study.

The research reporting the increased liver injury from the drugs, rifampin and pyrazinamide, was conducted by investigators at UCSF, Boston University, and Emory University and appears in the October 15 issue of the Annals of Internal Medicine.

The study is the first large

Mauna Loa – Hawaii’s biggest and potentially most destructive volcano – is showing signs of life again nearly two decades after its last eruption.

Recent geophysical data collected on the surface of the 13,500-foot volcano revealed that Mauna Loa’s summit caldera has begun to swell and stretch at a rate of 2 to 2.5 inches a year, according to scientists from the U.S. Geological Survey (USGS) and Stanford University. Surface inflation can be a precursor of a volcanic eruption

Foxd3 joins the small, but growing list of stem cell regulating genes

In the search to understand the nature of stem cells, researchers at the University of Pennsylvania School of Medicine have identified a regulatory gene that is crucial in maintaining a stem cell’s ability to self-renew. According to their findings, the Foxd3 gene is a required factor for pluripotency – the ability of stem cells to turn into different types of tissue – in the mammalian embryo. Their research is

For the first time, researchers have shown that magnetic resonance imaging (MRI) can predict the risk of heart attacks or cardiac deaths in coronary heart disease patients, according to a report in today’s rapid access issue of Circulation: Journal of the American Heart Association.

MRI can be used to locate tissue damage in a heart attack or pinpoint blockages, but it has not been used to predict heart attacks.

“This study is the first to determine that MRI is a strong prognos

Serious streptococcus infections is the theme of a major EU project to be coordinated and led by researchers from Lund University. Associate Professor Claes Schalen and researcher Aftab Jasir, both at the Department of Medical Microbiology, Dermatology, and Infections, Section for Bacteriology, are the coordinator and project leader, respectively. Group A streptococci (GAS) are also called killer bacteria since serious GAS infections can develop with dramatic rapidity.

“Since the late 1980s
