Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough…
The researchers describe their work in a paper accepted for publication in the Journal of the American Chemical Society, and posted on the journal’s Web site.Scientists have long been puzzled by nature’s ability to use cheap and plentiful building blocks – iron, nickel and sulfur – to achieve the catalytic performance seen in rare and expensive metals. In particular, two enzymes – iron-iron hydrogenase and nickel-iron hydrogenase – function as hydrogen processors, much like platinum….
Molecular biologists, including the cool dudes from CSI, use gel electrophoresis to separate DNA fragments from each other in order to analyse the DNA. A team…
This was made possible by a new approach for producing ultraclean nanotubes. Moreover, the team of researchers, under the leadership of Spinoza winner Leo…

The polymers contain mechanically active molecules called mechanophores. When pushed or pulled with a certain force, specific chemical reactions are triggered…
Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of…
This planetary nebula is known as Kohoutek 4-55 (or K 4-55). It is one of a series of planetary nebulae that were named after their discoverer, Czech…
Their technique, described in a recent paper,* could become an important quality-control tool to help monitor semiconductor manufacturing processes and…
The findings, detailed online in today's issue of Nature, may open the door to dramatically less expensive and more versatile lasers, brighter LED lighting,…
