A web of faults links the San Andreas Fault over a discontinuous 80-kilometer [50 mile] region in southern California. Carena et al. analyzed a gap in the famous fault line that runs from the Mojave Desert to the Coachella Valley and suggest that a network of seismically active faults likely connects the two strands of the 1,200-kilometer [750-mile] San Andreas Fault.
The researchers examined the three-dimensional geometry of the fault system in the complex region, reaching nearly 20 kilometers [10 miles] below the Earth’s surface. They report that the San Andreas devolves into a series of faults with varying configurations such that it would require an unlikely sequence of fault ruptures to trigger a massive earthquake involving both strands of the fault.
The authors also modeled several possible fault rupture scenarios for earthquakes in the Los Angeles area to determine the likelihood of a complex rupture.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
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...
