Take a deep breath. On Earth the air is easy to take for granted. It’s everywhere. But if you take a rocket into space the Earth’s atmosphere falls away. Astronauts understand this at an instinctive level. Unlike just about every other career in the world, astronauts must bring their own atmosphere to work. It is this essential nature about the atmosphere that generated such high expectations for NASA’s Aura satellite. Launched in July of 2004, this powerful research platform is already providing the first-ever daily, direct global measurements of low altitude or tropospheric ozone and many other pollutants that affect our air quality. Moreover, Aura delivers its results with unprecedented clarity over a region. The instruments onboard will help scientists monitor pollution production and transport around the world.
Measurements taken from the satellite also offer the potential for new insights into how climate changes influence the recovery of the stratospheric or upper ozone layer, the protective region that shields the Earth from ultra-violet radiation. "Data from NASA missions like Aura are a valuable national asset," said Phil DeCola, Aura Program Scientist, NASA Headquarters, Washington DC. " For example, clean air is a vital need, and air quality is not merely a local issue.

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...
