If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model that EPFL re...

Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other...

Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy's Oak Ridge National Laboratory supports a new approach to information storage and processing.

Drinking more milk as a teenager apparently does not lower the risk of hip fracture as an older adult and instead appears to increase that risk for men, according to a study.

The odds of preterm delivery appear to increase for pregnant women exposed to phthalates, chemicals people are exposed to through contaminated food and water and in a variety of products including lotions, perfumes and d...

Patients with acute coronary syndrome who were treated with the experimental drug varespladib were more likely to experience additional cardiovascular events -- including sudden death, heart attack and stroke -- than tho...

The overall use of breast magnetic resonance imaging has increased, with the procedure most commonly used for diagnostic evaluations and screenings, according to a study.

Giving beta-blocker medication to patients with heart disease undergoing noncardiac surgery appears to be associated with a lower risk of death and major adverse cardiovascular events 30 days after surgery in patients wi...

Vitamin B12 (cobalamin [Cbl]) is essential for maintaining healthy bodily function, but higher than normal levels (reference range 200-600 pmol/L) may indicate that a patient is at risk of developing certain cancers, acc...

Annual rates of CPR training in the United States are low and vary widely across the country, but the communities most in need of training are the least likely to be trained, according to a new study.

People with damage in the small blood vessels of the retina and kidneys are at increased risk to develop the most common type of abnormal heart rhythm, according to research.

Therapeutic hypothermia - cooling the body and brain down to 33°C - is the method used worldwide to treat cardiac arrest, even though a lower body temperature may raise the risk of side-effects. However, keeping the tem...

Pregnant women exposed to phthalates, a group of hormone-mimicking chemicals found in personal care products and processed foods, may have an increased risk of preterm delivery, a new study suggests.

New research has found no difference in outcomes at one-year between two recommended surgical options for treating ischemic mitral regurgitation -- repair of the leaky valve or its replacement with an artificial valve.

Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which...

Bioengineers have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of predicting the kind of environment wh...

Researchers have found an innovative way to study glucose regulation in the body: by transferring the vital insulin-producing cells from the pancreas to the eye. The latter can serve as a kind of window through which hea...

To produce vodka, you must first ferment a foodstuff that contains sugar or starch, then distill the product to increase its alcohol content. Today, most vodka comes from fermented grains, though you can also use potatoe...

A targeted effort to help high-risk heart failure patients stay on their medications did improve adherence to drug regimens, but had surprisingly little effect lowering hospital readmission rates, according to a study.

Researchers have found that a specific gene plays an important role in suppressing lymphoma, a type of blood cell cancer.

Biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young. They attract more females by making more urinary pheromones, but smelling sexier shorten...

Isoforms of PDE3A enzyme might make targets for drugs that prevent sudden cardiac death while still helping the heart pump blood.
