House maintenance is a never-ending and costly task. Roofing, siding, windows and even garage doors wear out.
Now researchers at the National Institute of Standards and Technology (NIST) have developed a software program that takes the guesswork out of replacement decisions. The free program, called NEST (for National Economic Service-life Tools), allows homeowners to select the most cost-effective replacement material for roofing, siding, windows and garage doors. It also provides, for the users own zip code, cost estimates for replacements, including the cost of local labor and local materials, as well as the cost of maintenance.
NEST currently consists of two software tools. "NEST Builder" and "Durability Doctor." NEST Builder asks homeowners to specify the house layout and size, as well as various kinds of materials used for roofing, siding, windows and garage doors. The software program uses the information to build a virtual or graphic model of a users home.

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...
