New research may improve long-term forecasting skills
The above map shows a snapshot of surface temperature in the Northern Hemisphere, with weather systems moving poleward. In the paper, the authors demonstrate that this process is influenced by the presence of a stratospheric jet.

Three members of Columbia’s Department of Applied Physics and Applied Mathematics have used a simple climate model to demonstrate how the weather systems and storms we experience may be influenced by disturbances in the Earth’s stratosphere, the upper layer of atmosphere between 10 and 30 miles high. This Earth Institute research was recently highlighted by the American Geophysical Union, following recent publication in the journal Geophysical Research Letters. “Our research shows that changes to the strength of winds in the stratosphere cause changes to tropospheric weather systems” explained lead-author Matthew Wittman.

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...
