Natural heart pacemakers?

Artificial heart pacemakers have saved and extended the lives of thousands of people, but they have their shortcomings - such as a fixed pulse rate and a limited life.

Rapid test shows whether Alzheimer's drugs are hitting their target

A test developed by physician-scientists at Washington University School of Medicine in St. Louis may help assess more quickly the ability of Alzheimer's drugs to affect one of the possible underlying causes of Alzheimer's disease in humans, accelerating the development of new treatments.

Large waist size tied to increased risk of heart failure in middle-aged and older populations

Adding to the growing evidence that a person's waist size is an important indicator of heart health, a study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has found that larger waist circumference is associated with increased risk of heart failure in middle-aged and older populations of men and women.

Study finds multidrug-resistant gram-negative bacteria high in long-term care

The prevalence of a certain form of drug-resistant bacteria, called multidrug-resistant gram-negative (MDRGN) organisms, far surpassed that of two other common antimicrobial-resistant infections in long-term care facilities, according to a study conducted by researchers at Hebrew SeniorLife's Institute for Aging Research.

Stem cell therapy used to restore transparency in corneas

Stem cells collected from human corneas restore transparency and don't trigger a rejection response when injected into eyes that are scarred and hazy, according to experiments conducted in mice by researchers at the University of Pittsburgh School of Medicine.

Small RNAs can play critical roles in male infertility/contraception

University of Nevada School of Medicine scientists in the Department of Physiology and Cell Biology have discovered insight into the reproductive workings of the male sex chromosome that may have significant implications for male infertility and contraception.

Researchers model 3D structures of proteins that control human clock

In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals.

Synthetic green-glowing genes show how 'silent' mutations influence protein production

Biologists at the University of Pennsylvania have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones.

New method predicts impact of anthrax release

A new statistical method that can estimate the origin and time of an aerosolized release of the pathogen causing anthrax, following detection of the first few cases has been developed by researchers from the Medical Research Council (MRC) Centre for Outbreak Analysis and Modelling at Imperial College London in collaboration with the Health Protection Agency's Microbial Risk Assessment group.
