Researchers at Los Alamos National Laboratory and the University of California, San Diego, have created the first computer simulation of full-system protein folding thermodynamics at the atomic-level. Understanding the basic physics of protein folding could solve one of the grand mysteries of computational biology.
Proteins are the basic building blocks of life and protein folding, the process by which proteins reconfigure themselves - the actions that result in structural change - are the foundation of cellular growth and the health of a biological system. When proteins incorrectly fold the malfunction can give rise to a variety of diseases. The fact that proteins fold has been known since the 1960s, but an understanding of the chemical and physical properties of folding continues to elude scientists.
Understanding how proteins undergo the folding process has largely been studied from a biologist’s point of view, probing actual proteins and studying them with high-powered microscopy techniques. Now, Los Alamos theoretical biophysicist Angel Garcia, along with colleague Jose N. Onuchic of UC San Diego, have created a computer model of protein folding that focuses on the physics of the protein folding, specifically looking at the temperature changes that occur in the process.

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...
