Scientists from Trinity College Dublin have gained key structural insights into the machinery employed by opportunistic, disease-causing bacteria, which may help chemists design new drugs to inhibit them.

Osaka University researchers, in collaboration with several Japanese companies, translate neuroimaging tools to study renal fibrosis in rat kidney. The technique is expected to replace the invasive biopsies currently used to identify patients at risk of developing chronic kidney disease.

E-cigarettes are often perceived to be less harmful than their traditional counterparts, but they could still expose the people who “vape” and those around them to harmful compounds. Researchers now report in ACS’ journal Environmental Science & Technology that heavy use and secondhand emissions could lead to inhaled levels of toxins that exceed set exposure limits. But under typical use, secondhand exposure would have a lower impact on health than second- and third-hand cigarette smoke.

Researchers at Uppsala University have developed a new method for very rapidly determining whether infection-causing bacteria are resistant or susceptible to antibiotics. The findings have now been published in the US journal Proceedings of the National Academy of Sciences (PNAS).

Patients without calcium buildup in the coronary arteries had significantly lower risk of future heart attack or stroke despite other high risk factors such as diabetes, high blood pressure, or bad cholesterol levels, new research from UT Southwestern cardiologists shows.

Research from McMaster University has identified new regulators of brain metastases in patients with lung cancer.

These regulators are the genes called SPOCK1 and TWIST2.

In the brains of Alzheimer’s patients, many of the genes required to form new memories are shut down by a genetic blockade, contributing to the cognitive decline seen in those patients.

MIT researchers have now shown that they can reverse that memory loss in mice by interfering with the enzyme that forms the blockade. The enzyme, known as HDAC2, turns genes off by condensing them so tightly that they can’t be expressed.

For several years, scientists and pharmaceutical companies have been trying to develop drugs that block this enzyme, but most of these drugs also block other members of the HDAC family, which can lead to toxic side effects. The MIT team has now found a way to precisely target HDAC2, by blocking its interaction with a binding partner called Sp3.

A new study by University of Kentucky Markey Cancer Center researchers shows that when therapy-sensitive cancer cells die, they release a "killer peptide" that can eliminate therapy-resistant cells.

Pregnant women are an important but thus far largely overlooked group vulnerable to the effects of extreme heat linked to climate change, according to new research by Sabrina McCormick, PhD, an Associate Professor of Environmental and Occupational Health at Milken Institute School of Public Health at the George Washington University.  

Drivers who drop off their kids at school should turn off their engines

We think of schools as safe places for children but an invisible hazard is lurking right outside the front door,  says a new study from the University of Toronto.
