Folk and herbal remedies are often used in the hope that they will prevent the common cold or reduce the severity and duration of symptoms. Yet, few of these compounds are evaluated scientifically.
In this study Predy and colleagues randomized 323 study subjects to receive a proprietary ginseng ( Panax quinquefolius ) preparation or a placebo and followed them for 4 months during the winter (September to April). Using predetermined criteria to determine if subject-reported symptoms were "colds," the authors found that ginseng reduced the frequency of colds. Subjects in the ginseng group reported having 2 or more colds less often than subjects in the placebo group (10% v. 23%). Symptom severity and duration were also lessened.
In a related commentary, Ronald Turner of the University of Virginia School of Medicine recently evaluated Echinacea angustifolia as a preventive herbal product for the common cold (and found it did not work). He cautions physicians and the public about the difficulties of doing clinical studies of common viral infections, especially when the specific viruses are not identified.

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...
