Researchers create designer 'barrel' proteins

Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport ...

Crystal structure of COP9 signalosome elucidated

Nicolas Thomä and his group at the Friedrich Miescher Institute for Biomedical Research have elucidated the crystal structure of the human COP9 signalosome, an important regulator of protein degradation. The crystal structure, ...

Green photon beams more agile than optical tweezers

Romanian scientists have discovered a novel approach for the optical manipulation of macromolecules and biological cells. Their findings, published in the European Physical Journal B, stem from challenging the idea that visible ...

A short cut to billion dollar drugs

(Phys.org)—Scientists have found a highly efficient method of making hormone-based drugs which could generate billions of sales for the pharmaceutical industry.

Inspired by genetics, chemistry finally takes hold of its own code

Nature proves every day that it is both complex and efficient. Organic chemists are envious of it; their conventional tools confine them to simpler achievements. Thanks to the work of professor Stefan Matile's team from the ...

New laser can point the way to new energy harvesting

New ultrafast laser equipment, capable of generating intense pulses of light as short as a few femtoseconds from the UV to the Infra Red, will help scientists at the University of East Anglia (UEA) measure how energy is transferred ...

Cells use water in nano-rotors to power energy conversion

Researchers from the Max Planck Institute of Biophysics in Frankfurt, and Mount Sinai School of Medicine in New York have provided the first atomic-level glimpse of the proton-driven motor from a major group of ATP synthases, ...
