Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery resolves a ten-year mystery surrounding this object. In Earth’s time frame, the estimated age of the neutron star in Cas A is only several hundred years, making it about ten times younger than [...]

Scientists in Belgium have successfully differentiated human embryonic stem cells (hESC) into major cell types of lung epithelial tissue using a convenient air-liquid interface. The technique could provide an alternative to lung transplants for patients with lung injury due to chronic pulmonary disease and inherited genetic diseases such as cystic fibrosis.

Using portable 3-D laser technology, scientists have electronically preserved a rare 110 million-year-old fossilized dinosaur footprint excavated in 1933, and built into the wall of a bandstand at a Texas courthouse. The laser image preserves an original track used to describe a species of dinosaur identified in 1935 as ichnospecies Eubrontes glenrosensis.

Scientists have an ambitious new strategy for untangling the evolutionary history of humans and their biological relatives: Create a genetic menagerie made of the DNA of more than 10,000 vertebrate species. The plan, proposed by an international consortium of scientists, is to obtain, preserve, and sequence the DNA of approximately one species for each genus [...]

Childhood obesity in the United States is reaching epidemic proportions. With more than one fourth of advertising on daytime and prime time television devoted to foods and beverages and continuing questions about the role television plays in obesity, a new study examines how food advertising aimed at children might be a large contributor to the [...]

A new study has found that statins have beneficial effects on patients with systolic heart failure, but those with diastolic heart failure experienced the opposite effect, including increased dyspnea, fatigue and decreased exercise tolerance.

Postmenopausal women who have higher testosterone levels may be at greater risk of heart disease, insulin resistance and the metabolic syndrome compared to women with lower testosterone levels, according to a new study. This new information is an important step, say researchers, in understanding the role that hormones play in women’s health.
