In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers - including 2007 Nobel Prize winner Mario R. Capecchi - have created a "switch" that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal
The mechanism by which 'polycomb' proteins critical for embyronic stem cell function and fate are targeted to DNA has been identified by UCL scientists.
When someone has a deadly disease or sustains a life-threatening injury, a transplant or graft of new tissue may be the best -- or only -- treatment option.
Drexel's Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish.
The work of a Kansas State University professor is challenging the assumption that genetically engineered plants are the great scientific and technological revolution in agriculture and the only efficient and cheap way to feed a growing population.
Yale scientists, working with the fruit fly as a model, have discovered how odors are encoded by the olfactory system into the complex messages that are sent to the brain.
For the first time, scientists have used a genetically engineered "friendly" bacterium to deliver a therapy.
Viruses cannot only cause illnesses in humans, they also infect bacteria. Those protect themselves with a kind of 'immune system' which - simply put - consists of specific sequences in the genetic material of the bacteria and a suitable enzyme. It detects foreign DNA, which may originate from a virus, cuts it up and thus makes the invaders harmless.
