Ever since the internet was created, it has developed and advanced as new services have been introduced that have made it easier to access and send data between remote computers. Electronic mail and the easy-to-use interactive interface known as the World Wide Web are just two of the most important services that have helped to make the internet as popular as it is today. GRID technology, one of the latest systems that has been developed for linking computing resources, connects hundreds of large computers so they can share not only data itself, but also data processing capability and large storage capacity. This technology has now taken an important step forward: the hardware and tools required to make the interface interactive have become available. The UAB has participated in the project, taking charge of creating software to coordinate access between the different computers in the new system.
The most important new feature is that the system is interactive. The user works with a “virtual desktop” using commands and graphics windows that allow clear and easy access to all the resources on the GRID network, just like when someone browses through folders on a laptop computer. This system has enormous potential in many different fields.
One possible application is in those fields in which one needs to transform large quantities of information into knowledge, using simulations, analysis techniques and data mining, to make decisions. For example, a surgeon working from a remote location who needed to suggest different configurations for a bypass operation using information obtained through a scan on the patient could compare different simulations and observe in real time the blood flow in each simulation. Thanks to the new interactive system the surgeon would be able to use the simulations to make the best possible decision.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
