Wide racial disparities found in coronary artery disease deaths
African American patients with coronary artery disease die at a significantly higher rate than white patients with the same degree of disease, according to an analysis of more than 20,000 patients by cardiologists at the Duke Clinical Research Institute.

Testing strengthens recall whether something's on the test or not
New research reveals that the simple act of taking a test helps you remember everything you learned, even if it isn't tested.

Scientists capture nanoscale images with short and intense X-ray laser
LLNL scientists for the first time have validated the idea of using extremely short and intense X-ray pulses to capture images of objects such as proteins before the X-rays destroy the sample.

Sports cheats beware -- new test detects previously undetectable drug
Injecting performance enhancing corticosteroid hormones for other than medical treatment is banned, and tests exist that can detect injected hormones.

Study reveals women find cancer caring a heavier burden than men
An ongoing study by the University of Western Sydney into the experience and needs of cancer carers has revealed that there are major differences in the way men and women cope with the role of caring for a loved-one with cancer.

What does the public really know about HPV?
Human papillomaviruses (HPV) are the most common sexually transmitted infections in the United States, and certain

MRI detects early heart damage in patients with sarcoidosis
To detect heart damage early in patients with the immune system disorder sarcoidosis, who are at elevated risk of dying from heart problems, magnetic resonance imaging is twice as sensitive as conventional methods, according to a study by Duke University Medical Center cardiologists.

Novel vaccine shows promise against early-stage breast cancer
A diagnosis of breast cancer has taken on a new meaning in the past 10 years, as research has produced a host of new therapies and detection techniques, significantly improving long-term survival for women who have been fighting the disease.

Cheaper color printing by harnessing Ben Franklin's electrostatic forces
Pioneered almost 300 years ago by Benjamin Franklin, the basic science of electrostatics has generated recent advances that could soon lead to color laser printers that are cheaper and up to 70 percent smaller than current models, a physicist reports at this week's AVS International Symposium and Exhibition in San Francisco.

Sperm proteome gives 'tantalizing glimpse' towards the origin of sex
The first ever catalogue of the different types of proteins found in sperm could help reveal the origins of sex and explain some of the mysteries of infertility, say scientists.

Fast test for low blood flow in dogs detects early heart trouble
Working with dogs and using the latest in imaging software and machinery, also known as a 64-slice CT scanner, Johns Hopkins heart specialists have developed a fast and accurate means of tracking blood that has been slowed down by narrowing of the coronary arteries.

Genes offer researchers a 'crystal ball' to help them prevent, diagnose and treat cancer
The science of cancer prevention has advanced to the point where researchers now say they can detect

Scientists urge collaborative action to address effects of global environmental change
Immediate, collaborative action by governments is necessary to ensure sustainable development in the face of unprecedented global environmental change, according to a statement released today by hundreds of scientists attending the Earth System Science Partnership Open Science Conference,

Cardiocerebral Resuscitation better than CPR for out-of-hospital cardiac arrest
New data show that in cases of out-of-hospital cardiac arrest, interrupting chest compressions for anything -- including mouth-to-mouth ventilations -- appears to be detrimental.
