Researchers at the University of Waterloo have invented a fast, affordable way for developing communities to test their drinking water for potentially deadly E. coli.

Unlike current tests that cost about $70 and can take up to three days to get back from the lab, the Waterloo invention uses paper strips similar to those in litmus tests to produce results in less than three hours at a cost of 50 cents.

MIT and Harvard University researchers have engineered E. coli cells that can be used to study how bacteria at an infection site respond to antibiotic treatment, allowing scientists to learn more about how existing antibiotics work and potentially help them to develop new drugs.

In the new study, which appears in the Aug. 31 issue of Cell Host and Microbe, the researchers found evidence that some existing hypotheses about how bacteria respond to antibiotics are not correct.

UCLA biologists have developed an intervention that serves as a cellular time machine — turning back the clock on a key component of aging.

Researchers have developed the first tool that can diagnose Parkinson’s disease when there are no physical symptoms, offering hope for more effective treatment of the condition.

The Singapore Chinese Health Study reveals increased risk of diabetes with higher intake of red meat and poultry, partially attributed to the dietary iron content in these meats.

As more people live into their 80s and 90s, researchers have delved into the issues of health and quality of life during aging. A recent mouse study at the UC Davis School of Veterinary Medicine sheds light on those questions by demonstrating that a high-fat, or ketogenic, diet not only increases longevity, but improves physical strength.

Scientists have developed a camera that can see through the human body.

The camera is designed to help doctors track medical tools known as endoscopes that are used to investigate a range of internal conditions.

An existing drug may one day protect premenopausal women from life-altering infertility that commonly follows cancer treatments, according to a new study.

People with serious mental illness, such as bipolar disease and schizophrenia, die on average 25 years earlier than their peers. A common cause of death is heart disease that frequently develops unchecked due to lack of preventive care.

A new study has found a troubling lack of adherence to a potentially lifesaving treatment regimen among breast cancer patients who take opioids to manage their pain.
