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.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
