A group of researchers from The Scripps Research Institute (TSRI) have solved the structure of an enzyme that modulates central nervous system (CNS) functions such as pain perception, cognition, feeding, sleep, and locomotor activity.
The enzyme, described in the latest issue of the journal Science, is called fatty acid amide hydrolase (FAAH), and it breaks down certain fatty signaling molecules that reside in the lipid membranes of CNS cells. The TSRI group reports that FAAH modulates the action of these fatty signaling molecules through an unusual mechanism of action whereby it scoops them out of the cell membranes and chews them up.
"I envision that if someone could make a specific inhibitor to FAAH, you could, in principal, get pain relief without any of the side effects," says Benjamin Cravatt, one of the paper’s lead authors and an investigator in TSRI’s Department of Cell Biology, Department of Chemistry, and The Skaggs Institute for Chemical Biology.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

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...
