Nature is a seemingly endless storehouse of interesting - and potentially life-saving - biological molecules. But tracking down and harvesting those chemicals in their natural form can be time-consuming, expensive and unreliable.
Now Salk scientists have discovered a new way of bringing "bio-prospecting" out of the rainforest and into the lab. Their findings are published in the June 16th edition of the journal Nature.
Stéphane Richard, Joseph Noel and Tomohisa Kuzuyama isolated and examined a totally new enzyme that can mix and match biological chemicals to create a wide range of different molecules that could be used as the basis for new drugs. The enzyme, named Orf2, takes chemical building blocks known as small aromatic molecules and changes them by adding a fat-like molecule called a prenyl group. That modification can have a huge impact on where the aromatic molecule goes within the cell, and what sort of effects it has when it reaches its target.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
