Calcium in arteries influences heart attack risk
August 8, 2017 03:32 PM - UT Southwestern Medical Center

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.

Blocking a key enzyme may reverse memory loss
August 8, 2017 03:27 PM - Massachusetts Institute of Technology

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.

New Study Discovers "Killer Peptide" That Helps Eliminate Resistant Cancer Cells

Extreme heat linked to climate change may adversely affect pregnancy
August 8, 2017 02:33 PM - George Washington University

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.  

Every breath you take: Air pollution from idling cars puts kids at risk

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.

Scientists reveal source of human heartbeat in 3D
August 4, 2017 03:49 PM - University of Manchester

A pioneering new study is set to help surgeons repair hearts without damaging precious tissue.

A team of scientists from Liverpool John Moores University (LJMU), The University of Manchester, Aarhus University and Newcastle University, have developed a way of producing 3D data to show the cardiac conduction system - the special cells that enable our hearts to beat – in unprecedented detail. The findings were published in Scientific Reports.
