A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars. Research results from Chalmers University of Technology and Technical University of Denmark show that it is possible to significantly reduce the need for platinum, a precious and rare metal, by creating a nanoalloy using a new production technique. The technology is also well suited for mass production.

“A nano solution is needed to mass-produce resource-efficient catalysts for fuel cells. With our method, only 1/10 as much platinum is needed for the most demanding reactions...

This is an artist’s impression of a quasar and neighboring merging galaxy. The galaxies observed by the team are so distant that no detailed images are possible at present. This combination of images of nearby counterparts gives an impression of how they might look in more detail.

A team of astronomers has discovered a new kind of galaxy which, although extremely old – formed less than a billion years after the Big Bang – creates stars more than a hundred times faster than our own Milky Way. The team’s discovery could help solve a cosmic puzzle – a mysterious population of surprisingly massive galaxies from when the universe was only about 10% of its current age...

A team of international astrophysicists led by ANU has shown how most of the antimatter in the Milky Way forms. Antimatter is material composed of the antiparticle partners of ordinary matter – when antimatter meets with matter, they quickly annihilate each other to form a burst of energy in the form of gamma-rays. Scientists have known since the early 1970s that the inner parts of the Milky Way galaxy are a strong source of gamma-rays, indicating the existence of antimatter, but there had been no settled view on where the antimatter came from.

The Clostridium botulinum bacterium (shown here in colonies) can cause foodborne illnesses and potentially deadly effects due to the neurotoxin it produces. Credit: CDC

Botulinum neurotoxin is probably best known to Americans as BOTOX rather than as a cause of potentially dangerous foodborne illnesses. Lesser known is that Clostridium botulinum, the bacterium that causes the neurointoxication, produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists a serendipitous discovery by TSRI scientists may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.
