Marine bacterium sheds light on control of toxic metals

An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper, in research led by the University of East Anglia (UEA).

Turbocharging fuel cells with a multifunctional catalyst

Powering clean, efficient cars is just one way fuel cell technology could accelerate humanity into a sustainable energy future, but unfortunately, the technology has been a bit sluggish. Now, engineers may be able to essentially ...

Engineers figure out how to make more efficient fuel cells

Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce ...

High-efficiency zinc-air battery developed

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the ...

A star explodes, turns inside-out

(PhysOrg.com) -- A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process. Using very long observations of Cassiopeia A ...

Oldest objects in solar system indicate a turbulent beginning

(PhysOrg.com) -- Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system.
