Employing high-tech, digital X-ray microtomography (microCT), Northwestern University scientists have discovered the way in which newts form new bone and cartilage during limb regeneration. Newts are a type of salamander, the only vertebrates capable of rebuilding lost structures such as limbs throughout their lifetimes.
Reporting in the January issue of Developmental Dynamics, Northwestern researchers Hans-Georg Simon and Stuart Stock showed that bone formation in a regenerated forelimb combines elements of embryonic development and of adult wound healing.
Results of their research, which have not been observed before in other studies, may have implications for replacement of limb parts missing from injury or birth defects, and, ultimately, for growing new tissue from parts of organs such as livers.

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...
