Two new studies cast doubt on whether sex offender registry and notification laws actually work as intended.

Ongoing research is exploring the use of virus-produced proteins that destroy bacterial cells to combat potentially dangerous microbial infections. Bacteriophages produce endolysin proteins that specifically target certain bacteria, and one team of scientists has been studying one that destroys Clostridium difficile, a common source of hospital-acquired infections. New research is ...

For the first time, researchers have demonstrated the feasibility of using serial positron emission tomography scans, using a special estrogen-containing isotope, to confirm the relative effectiveness of estrogen-blocking and estrogen-depleting therapy in patients with metastatic breast cancer.

A promising gene therapy developed to prevent and reverse congestive heart failure is on the verge of clinical trials, after years of proving itself highly effective in the lab and a large animal study.

In an era of skyrocketing health-care costs and finite financial resources, health economists are increasingly called upon to determine which medical treatments are the most cost-effective. Now two researchers suggest a way to tailor this cost-benefit analysis (more accurately known as an incremental cost-effectiveness ratio, or ICER) more precisely to ...

Scientists determined the formaldehyde removal efficiency of a diverse cross-section of 86 indoor plant species. Ferns had the highest formaldehyde removal efficiency of the five classes of plants used in the experiments. Osmunda japonica (Japanese royal fern) was the most effective at removing formaldehyde of the species tested, proving 50 ...

New research compares effectiveness of various drugs and diets as treatments for controlling seizes often experienced by children with autism.

Administering both the pneumococcal and the herpes zoster vaccines to patients during the same visit is beneficial and does not appear to compromise the protective effect of the zoster vaccine, according to a new study.

When infants' tear ducts are blocked, the decision about when to intervene and the cost-effectiveness of doing so depend on how likely it is the problem will self-resolve, according to a new report.

Only about half of new drugs approved in the last decade had comparative effectiveness data available at the time of their approval by the U.S. Food and Drug Administration, and approximately two-thirds of new drugs had this information available when alternative treatment options existed, according to a study in the ...

Only about half of new drugs approved in the last decade had comparative effectiveness data available at the time of their approval by the US Food and Drug Administration, and approximately two-thirds of new drugs had this information available when alternative treatment options existed, according to a new study.

A study in mice and in a human population shows that use of anti-inflammatory drugs reduces the effectiveness of SSRIs, the most widely used class of antidepressant medications.
