Using sophisticated computer algorithms running on standard desktop computers, researchers have designed and constructed a novel functional protein that is not found in nature. The achievement should enable researchers to explore larger questions about how proteins evolved and why nature “chose” certain protein folds over others.

The ability to specify and design artificial proteins also opens the way for researchers to engineer artificial protein enzymes for use as medicines or industrial catalysts, said the studys lead author, Howard Hughes Medical Institute investigator David Baker at the University of Washington.
Baker and colleagues Brian Kuhlman, who is now at the University of North Carolina, Chapel Hill, and graduate student Gautam Dantas at the University of Washington, published their studies in the November 21, 2003, issue of the journal Science. The scientists collaborated on the studies with other researchers at the University of Washington and the Fred Hutchinson Cancer Research Center in Seattle.

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...
Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
