Researchers find many men with low-risk, localized prostate cancers can safely choose observation instead of undergoing immediate treatment and a have better quality of life while reducing health care costs.

Using drugs to treat an infection could allow other co-existing conditions to flourish, a study in wild animals has shown.

Researchers have found that antibodies against the human papillomavirus may help identify individuals who are at greatly increased risk of HPV-related cancer of the oropharynx, which is a portion of the throat that contains the tonsils.

Researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity.

The quality of wakefulness affects how quickly a mammal falls asleep, researchers report in a study that identifies two proteins never before linked to alertness and sleep-wake balance.

Scientists have identified a highly promising new anti-tuberculosis compound that attacks the tuberculosis bacterium in two different ways.

Scientists have generated patient-specific beta cells, or insulin-producing cells, that accurately reflect the features of maturity-onset diabetes of the young.

The lipidation states (or modifications) in certain proteins in the brain that are related to the development of Alzheimer disease appear to differ depending on genotype and cognitive diseases, and levels of these protein and peptides appear to be influenced by diet, according to a new report.

A special type of in vitro fertilization, or IVF, may increase the risk for insulin resistance among children conceived in this way, according to a new study from Greece.

Low testosterone worsens the harmful effects of obesity in the nervous system, a new study in mice finds.

A new study shows that the predator-prey relationship can affect the flow of carbon through an ecosystem. This previously unmeasured influence on the environment may offer a new way of looking at biodiversity management and carbon storage for climate change.

New research findings could reduce production times and therefore costs for antibiotic producers.

An algorithm makes it possible to measure the dimensions of a room using just a few microphones and a snap of your fingers. There are many promising applications on the horizon.

In autism, brain regions tailored to respond to voices are poorly connected to reward-processing circuits, according to a new study.

Ocean acidification due to rising carbon dioxide levels will reduce the density of coral skeletons, making coral reefs more vulnerable to disruption and erosion, according to a new study of corals growing where submarine springs naturally lower the pH of seawater. The study is the first to show that corals are not able to fully acclimate to low pH conditions in nature.

The first experimental drug to boost brain synapses lost in Alzheimer's disease has been developed by researchers.

Sustainability programs are a Goldilocks proposition -- some groups are too big, some are too small, and the environment benefits when the size of a group of people working to save it is just right. Scientists have found a sweet spot -- a group size at which the action is most effective. More importantly, the work revealed how behaviors of group members can pull bad policy up or drag good policy down.

Controlling health care costs is crucial for manufacturers to remain competitive. That's why researchers are working with manufacturers to determine if employee wellness programs will cut costs and improve productivity.

Obese adolescents are more likely than their normal-weight counterparts to have hearing loss, according to results of a new study. Findings showed that obese adolescents had increased hearing loss across all frequencies and were almost twice as likely to have unilateral (one-sided) low-frequency hearing loss.

A new drug called pyrvinium pamoate inhibits aggressive forms of prostate cancer that are resistant to standard drugs, according to a study conducted in an animal model.
