Eliminating tooth decay: Breakthrough in dental plaque research

Dutch professors Bauke Dijkstra and Lubbert Dijkhuizen have deciphered the structure and functional mechanism of the glucansucrase enzyme that is responsible for dental plaque sticking to teeth. This knowledge will stimulate ...

A miniature synchrotron for your home lab

In 2004 Lyncean Technologies announced the construction of the Compact Light Source (CLS), a miniature synchrotron which uses inverse Compton scattering to produce high-intensity, tunable, near-monochromatic x-ray beams. ...

New player emerges in mapping protein structures

(Phys.org) —If you keep up with biology, you've probably seen those colorful images in which the atom-by-atom structure of a protein is portrayed by a tangle of ribbons. For the past couple of decades, scientists have been ...

Sticky antibodies block prion disease

(PhysOrg.com) -- Antibodies that stick to a brain prion protein called PrP could be the key to treating prion diseases like variant CJD and preventing people accidentally exposed to prions from going on to develop the fatal ...

Iron-sulfur enzymes as candidates for antibiotic development

The iron-sulfur protein IspH plays a central role in the terpene metabolism of several pathogens. The mechanism of the reaction provides an approach for developing new antibiotics, particularly against malaria and tuberculosis. ...

Forgotten and lost - when proteins 'shut down' our brain

(PhysOrg.com) -- Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) ...

The eukaryotic ribosome unveils its structure

One year after the Nobel Prize in chemistry was awarded for the discovery of the bacterial ribosome's atomic structure, French researchers from the Institut de Genetique et de Biologie Moleculaire et Cellulaire have determined ...
