The collagen changes its crystallinity in response to physical forces, so the ordered arrangement in collagen molecules of the cartilage in our knees may be flipping from one structural state to another with every step we take.
By employing molecular biology tools, a team of researchers measured the way mercury affects the gene expression of algae, even when its concentration in water is very low, comparable to European environmental protection standards.
New research results may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.
Scientists have synthesized a complex sugar molecule which specifically binds to the tumor protein Galectin-1. This could help to recognize tumors at an early stage and to combat them in a targeted manner.
