Two NASA California centers have been selected to develop new space-aged technologies that could be game-changers in the way we look at planets from above and how we safely transport robots or humans through space and bring them safely back to Earth. (more…)
In this week’s Science magazine, an energy expert advocates investing in “the other fuel cell” to reduce reliance on fossil fuels now, not in decades.
COLLEGE PARK, Md.– When most people hear the words “fuel cell,” they think of eco-friendly, hydrogen-powered cars that emit nothing more than water. (more…)
Engineers at Yale University have developed a new, highly efficient technique for separating, sorting, and concentrating synthetic microscopic particles within complex fluids based on size.
The new technique suggests the possibility of significant clinical, diagnostic, and pharmaceutical applications, such as isolating rare liquid-borne pathogens, monitoring tumor cells in bloodstreams, and rapidly assessing blood cell counts, for example. (more…)
PASADENA, Calif. — Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.
The data suggest there is significant exchange between Europa’s icy shell and the ocean beneath. This information could bolster arguments that Europa’s global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings are published in the scientific journal Nature. (more…)
The birth of the Gamburtsev Subglacial Mountains buried beneath the vast East Antarctic Ice Sheet – a puzzle mystifying scientists since their first discovery in 1958 – is finally solved. The remarkably long geological history explains the formation of the mountain range in the least explored frontier on Earth and where the Antarctic Ice Sheet first formed. The findings are published this week in the journal Nature. (more…)
GAINESVILLE, Fla. — Some endangered animals may live in smaller habitats than scientists realize, leading to inflated estimates of their ability to survive, according to a new University of Florida study. (more…)
Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.
In contrast, mature cells in children and adults depend more on cell mitochondria to convert sugar and oxygen into carbon dioxide and water during a high energy–producing process called oxidative phosphorylation. (more…)
A team of researchers led by the University of Colorado Boulder has discovered the first prehistoric bronze artifact made from a cast ever found in Alaska, a small, buckle-like object found in an ancient Eskimo dwelling and which likely originated in East Asia. (more…)
