Study: New risk score tool more accurately predicts patients' risk for cardiac disease and death
By combining patients' Framingham Risk Score with new Intermountain Risk Score, researchers found that they were 30 percent more likely to correctly determine a woman's risk, and 57 percent more likely to determine a man's risk for a cardiovascular problem or death within 30 days of an angiography.

Psychopaths' brains wired to seek rewards, no matter the consequences
The brains of psychopaths appear to be wired to keep seeking a reward at any cost, new research from Vanderbilt University finds.

Unlocking the opium poppy's biggest secret
Researchers at the University of Calgary have discovered the unique genes that allow the opium poppy to make codeine and morphine, opening the door to alternate methods of producing these effective painkillers either by manufacturing them in a lab or controlling the production of these compounds in the plant.

New cancer drug screening technique more closely mirrors reality
Improving on traditional screening tests for potential anti-cancer drugs, scientists at Dana-Farber Cancer Institute have developed a laboratory technique that more closely simulates the real-world conditions in which tumor cells mingle with the body's normal cells.

Light-activated 'warhead' turns modest molecules into super protein killers
Using a novel light activation technique, Scripps Research Institute scientists have been able to turn molecules with only a modest ability to fight specific proteins into virtual protein destroyers.

Plaque on CT scan is strong predictor of heart disease, worse long-term outcomes
The presence of plaque on an abdominal CT scan is a strong predictor of coronary artery disease and mortality, according to a Henry Ford Hospital study.

New defenses deployed against plant diseases
An international team led by scientists at the Sainsbury Laboratory in Norwich,UK, have transferred broad spectrum resistance against some important plant diseases across different plant families.

Superconductors on the nanoscale
A new experiment shows how adjacent regions affect each other in superconductors, and suggests ways that the materials could be improved by controlling their nanoscopic structures.

Lithium-ion anode uses self-assembled nanocomposite materials to increase capacity
A new high-performance anode structure based on silicon-carbon nanocomposite materials could significantly improve the performance of lithium-ion batteries used in a wide range of applications from hybrid vehicles to portable electronics.

New microscopy technique offers close-up, real-time view of cellular phenomena
For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs).

UF researcher urges caution in reducing blood pressure in patients with diabetes, coronary disease
Systolic blood pressure levels between 130 and 140 appear to be the most healthful for patients with both diabetes and coronary artery disease, according to findings from the American College of Cardiology's 59th annual scientific session in Atlanta.

New analysis of the structure of silks explains paradox of super-strength
Spiders and silkworms are masters of materials science, but scientists are finally catching up.

Study results leave search for new diabetes and heart disease treatments unresolved
Treatment with the anti-hypertensive drug valsartan (Diovan) led to a modest reduction in the development of type 2 diabetes but did not significantly reduce cardiovascular events in patients with impaired glucose tolerance, according to researchers at Duke University Medical Center and the University of Oxford.

Was the recent US stock market drop accompanied by more heart attacks? Duke studies relationship
A novel report explores the possible relationship between fluctuations in the stock market and the incidence of local heart attacks.

Family history is strong predictor of obstructive coronary artery disease using CCTA
In the largest study of its kind to date using cardiac computed tomography angiography, people with a family history of early signs of coronary artery disease are at higher risk of developing obstructive coronary artery disease and plaque in their arteries, Henry Ford Hospital researchers say.

UC Irvine biologists help sequence Hydra genome
An international team of scientists have sequenced the genome of Hydra, a freshwater polyp that's been a staple of biological research for 300 years.

ACCORD: Intensive BP, combined lipid therapies do not help adults with diabetes
Lowering blood pressure to normal levels -- below currently recommended levels -- did not significantly reduce the combined risk of fatal or nonfatal cardiovascular disease events in adults with type 2 diabetes who were at especially high risk for cardiovascular disease events, according to new results from the landmark Action to Control Cardiovascular Risk in Diabetes clinical trial.

Regadenoson is safe, effective for use in heart transplant patients
The drug regadenoson is safe and poses fewer side effects than the conventional medication used during a cardiac nuclear stress test of heart transplant patients, according to a Henry Ford Hospital study.
