Transfusion of Synthetic Blood Saves Woman’s Life
Posted by admin in Medicine, Science on 06. May, 2011 | 0 Comments
Blood Supply Donor blood goes bad, requires refrigeration, and can carry pathogens. Researchers are seeking synthetic alternatives that are universal to make up for short supplies of the real thing. A synthetic blood substitute is something of a holy grail in medical research. Many potential synthetics have been tried–DARPA has even put a blood substitute [...]
Hands-free faucets not necessarily better, say scientists

European regulators have approved the sale of a new medical implant intended to be a less invasive option than gastric bypasses or stomach stapling procedures: a “gastric pacemaker” for the gut. When a person is eating, a device implanted in the abdomen triggers a premature notion of fullness by stimulating stomach nerves. The device, made [...]

The organs were grown from the patients’ own cells Growing Spare Urethras in the Lab From the patient’s own cells. Six years ago, researchers at the Wake Forest Institute for Regenerative Medicine used tissue-engineering techniques to grow new urethras for five young male patients from their own cells. Now, an article published in the Lancet [...]
Princeton Researchers Construct Wholly Artificial Proteins That Can Sustain Cell Life
Posted by admin in Science on 07. Jan, 2011 | 0 Comments
Proteins of All Stripes Princeton researchers have made a variety of proteins from amino acid sequences not found in nature. Those proteins have shown the ability to function nearly as well as natural proteins in living cells in the lab. In a breakthrough that’s sure to stir up some controversy, Princeton researchers have reported that [...]
