Significant numbers of female high school athletes and non-athletes suffer from one or more components of the female athlete triad, a combination of three conditions that can lead to cardiovascular disease, according to a new study.

Recent research has shown that adult mouse and human cells can be transformed, or "reprogrammed" into a primitive, stem-cell state, but the process is inefficient and poorly understood. Now, thanks to the application of powerful new integrative genomic tools, scientists have uncovered significant new information about the molecular changes that underlie the direct reprogramming process.

The world's first optical pacemaker has been devised. Powerful, but very short, laser pulses can help control the beating of heart muscle cells.

Ships are inadvertently carrying trillions of stowaways in the water held in their ballast tanks. When the water is pumped out, invasive species could be released into new environments. Disease-causing microbes could also be released, posing a risk to public health, according to an article in Microbiology Today.

A study in Anesthesiology could represent an important step toward the eventual use of carbon monoxide to promote cell survival and reduce lung inflammation in patients undergoing cardiopulmonary bypass surgery. Scientists used low doses of inhaled CO in pig models while employing beating-heart cardiopulmonary bypass surgery.

Microspheres carrying targeted nucleic acid molecules fabricated in the laboratory have been shown to prevent and even reverse new-onset cases of type 1 diabetes in animal models. Currently,scientists are conducting a clinical trial of their leukapheresis-based dendritic cell approach in humans at the Children's Hospital. This Phase 1 clinical trial has been approved by the U.S. Food and Drug Administration (FDA).

Researchers have uncovered definitive evidence that a small but potent subset of immune system B cells is able to regulate inflammation. Using a new set of scientific tools to identify and count these cells, the team showed that these B cells can block contact hypersensitivity, the type of skin reactions that many people have when they brush against poison ivy.

Using a breakthrough technology, researchers led by a Weill Cornell Medical College scientist have pinpointed the hormone estrogen as a key player in about half of all prostate cancers.

The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.

Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons.
