For Tadeusz Molinski, the sea is full of riches -- and he does not mean oil fields or fisheries. Molinski, a professor of chemistry at the University of California, Davis, is searching for new treatments for cancer, infectious diseases and other conditions that could be made from natural products in the soft bodies of some of the oceans simplest inhabitants.
"Three quarters of the world is covered by oceans, and weve only dipped below the surface," Molinski said.
This chemist sees natural products from marine organisms as an opportunity to answer questions in biology and find potential leads for the next generation of drugs, whether those are anti-fungals or treatments for cancer. Many pharmaceutical drugs on the market, from aspirin to cholesterol-lowering "statins," are derived from natural products such as plants or bacteria. Molinski says modern developments in analytical chemistry, including highly sensitive instrumentation, sophisticated screening capabilities and discoveries from mapping the human genome, have created a renaissance of interest in these sources of potential medicines.

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...
