Where did Earth's global ocean come from? A team of Arizona State University geoscientists led by Peter Buseck, Regents' Professor in ASU’s School of Earth and Space Exploration (SESE) and School of Molecular Sciences, has found an answer in a previously neglected source. The team has also discovered that our planet contains considerably more hydrogen, a proxy for water, than scientists previously thought.

Scientists have shown that a bird found in Pennsylvania is the offspring of a hybrid warbler mother and a warbler father from an entirely different genus—a combination never recorded before now and which resulted in a three-species hybrid bird. This finding has just been published in the journal Biology Letters.

In the course of an extensive Antarctic expedition, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently investigated several lakes beneath Recovery Glacier that had been previously detected by satellite remote sensing. The experts found very few substantial bodies of water, which is a surprising result: up to that point, the scientific community had assumed that overflowing lakes below the East Antarctic Ice Sheet were the reason that ice masses began sliding and forming ice streams to begin with. This new study has just been released in the Journal of Geophysical Research.

A new study by Washington State University researchers suggests that a protein called CDK2 plays a critical role in heart damage caused by doxorubicin, a commonly used chemotherapy drug.

North China (35°–40°N, 110°–120°E) is a major region in China for winter wheat agriculture. It is in the spring (March to May) in this region that the reviving, jointing and booting stages of winter wheat mainly happen.

Tropical Cyclone 03S formed in the Southern Indian Ocean and the NOAA-20 satellite passed overhead and captured a visible image of the storm.

Lack of varied seasons and temperatures in tropical mountains have led to species that are highly adapted to their narrow niches, creating the right conditions for new species to arise in these areas, according to a new study published Nov. 5 in the Proceedings of the National Academy of Sciences.

People younger than age 40 who have high blood pressure are at increased risk of heart failure, strokes and blood vessel blockages as they age, according to a study in JAMA led by a Duke Health researcher.

Sixty-nine pharmaceutical compounds have been detected in stream insects, some at concentrations that may threaten animals that feed on them, such as trout and platypus. When these insects emerge as flying adults, they can pass drugs to spiders, birds, bats, and other streamside foragers. These findings by an international team of researchers were published today in Nature Communications.

A lumpy disc of dark-gray steel covers a bench in the lab space of Boston Metal, an MIT spinout located a half-hour north of its namesake city.
