Researchers from the Harvard Stem Cell Institute and Children’s Hospital Boston have discovered a new way to reprogram adult cells into pluripotent stem cells, which are very similar to embryonic stem cells. Their process, which uses mRNA to reprogram the cell without weakening its genetic integrity is up to 100 times more efficient than the current methods used to create these induced pluripotent stem cells, also known as iPS cells, says lead researcher Derrick Rossi, PhD.
A team of international researchers at the University of Sydney has created an aluminum alloy that is as strong as steel but much lighter. Aluminum, which is the most abundant metal in the earth’s crust, is normally very weak, easily bending to weights its stronger metal cousin, steel, can hold up. For years, scientists have been trying to manufacture a titanium-like metal, something both lightweight and stronger than steel, but without titanium’s high price-tag.
