How do neural stem cells decide what to be -- and when?
- EurekAlert
- 10/11/15 06:00
Researchers at Duke-NUS Graduate Medical School in Singapore have uncovered a novel feedback mechanism that controls the delicate balance of brain stem cells. Zif, a newly discovered protein, controls whether brain stem cells renew themselves as stem cells or differentiate into a dedicated type of neuron (nerve cell).

Internal body clock controls fat metabolism, UCI study shows
- EurekAlert
- 10/11/15 06:00
UC Irvine researchers have discovered that circadian rhythms -- the internal body clock -- regulate fat metabolism. This helps explain why people burn fat more efficiently at certain times of day and could lead to new pharmaceuticals for obesity, diabetes and energy-related illnesses.
Iron in coronary artery plaque is a marker of heart attack risk, say Mayo Clinic researchers
- EurekAlert
- 10/11/15 06:00
Plaque in a heart artery looks threatening, but cardiologists know that many of these buildups will not erupt, dislodge and block a vessel, causing a heart attack that can be fatal. Some will, however, and the challenge is to figure out atherosclerotic plaque that is dangerous and treat or remove it.
Is heart disease genetic destiny or lifestyle?
- EurekAlert
- 10/11/15 06:00
Is cardiovascular health in middle age and beyond a gift from your genes or is it earned by a healthy lifestyle and within your control? Two large studies from Northwestern Medicine confirm that a healthy lifestyle has the biggest impact on cardiovascular health. The studies were presented Nov. 15 at the American Heart Association Scientific Sessions.

Mastermind steroid found in plants
- EurekAlert
- 10/11/15 06:00
Scientists have known how important plant steroids called brassinosteroids are for regulating plant growth and development. But until now, they did not know how extensive their reach is. Now Carnegie researchers have identified about a thousand brassinosteroid target genes showing links between the steroid and numerous cellular functions and other hormonal chain reactions. The study is the first...
Microsensors offer first look at whether cell mass affects growth rate
- EurekAlert
- 10/11/15 06:00
University of Illinois researchers are using a new kind of microsensor to answer one of the weightiest questions in biology -- the relationship between cell mass and growth rate. Each microsensor is a small, suspended platform with a resonance frequency that changes as the cells on it grow heavier. Researchers tacked individual cells' masses and divisions over time and found that the cells they...
Missed opportunities: Most heart attack patients are not taking preventive medications
- EurekAlert
- 10/11/15 06:00
Despite a high frequency of cardiac risk factors, patients without known coronary artery disease presenting with acute heart attacks, or ST-elevated myocardial infarction, are rarely on primary prevention medications, according to study findings to be presented Nov. 15 at the 2010 annual American Heart Association Scientific Sessions in Chicago.
Molecular evolution proves source of HIV infection in criminal cases
- EurekAlert
- 10/11/15 06:00
In 2009, a Texas jury sentenced Philippe Padieu to 45 years in prison for aggravated assault with a deadly weapon -- having sex with women and not telling them he had HIV. A part of the evidence identifing him as the source of the women's infection came from experts at Baylor College of Medicine and the University of Texas at Austin.In a report in the Proceedings of the National Academy of...

University of Michigan researchers have determined that most types of melanoma cells can form malignant tumors, providing new evidence that the deadliest form of skin cancer does not conform to the increasingly popular cancer stem cell model.
More fat around internal organs may mean more complications after liver surgery
- EurekAlert
- 10/11/15 06:00
The amount of intra-abdominal fat appears to be associated with the risk of complications following major liver surgery, according to a report in the November issue of Archives of Surgery, one of the JAMA/Archives journals. However, appearing overweight or having a high body mass index were not associated with increased post-surgical risks.
Most value-added impact from teachers fades within 1 year

Natural compound shows promise against Huntington's disease
- EurekAlert
- 10/11/15 06:00
Fisetin, a naturally occurring compound found in strawberries and other fruits and vegetables, slows the onset of motor problems and delays death in three models of Huntington's disease, according to researchers at the Salk Institute for Biological Studies. The study, published in the online edition of Human Molecular Genetics, sets the stage for further investigations into fisetin's...
New blood test may help predict heart failure in apparently healthy older adults
- EurekAlert
- 10/11/15 06:00
Researchers at the University of Maryland School of Medicine in Baltimore report that a new, highly sensitive investigative blood test may help predict the risk of heart failure and cardiovascular death much earlier than previously possible in older people who do not have symptoms of heart failure. The test for troponin T, a marker for heart failure, detected levels 10 times lower than previous...
New research changes understanding of C4 plant evolution
- EurekAlert
- 10/11/15 06:00
A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene...
