"When the researchers pre-treated the nasal membrane of the mice with an enzyme called hyaluronidase to loosen the junctions between epithelial cells, even more stem cells entered the brain through the nose.

Other researchers have shown that you can also deliver therapeutic proteins such as neural growth factor into the brain in this way. If the results of this study can be repeated in humans, snorting stem cells might be a way of getting large numbers of cells into the brain without surgery. Repeated doses could also be given in the form of nasal drops." Your Warren Ellis moment for the week.

"Many of us have been deeply concerned about some of the clinics that are offering untested, and often illogical 'stem cell' treatments," he says. "They take advantage of desperate individuals or their family members, charging them large sums of money for procedures that are unlikely to work, may in fact be dangerous, and may use cells of dubious origin."

Lovell-Badge advises people to seek help from doctors, patient groups, disease societies, and charities, and to "thoroughly check the clinic and the procedures on offer before gambling away your money and hope."

Like that's gonna work.

"The idea stemmed from the observation that stem cells from the cornea (the thin, transparent barrier at the front of the eye) stick to contact lenses. Employing three patients who were blind in one eye, the researchers obtained stem cells from their healthy eyes and cultured them in extended wear contact lenses for ten days. The surfaces of the patients’ corneas were cleaned and the contact lenses inserted. Within 10 to 14 days the stem cells began to recolonize and repair the cornea." So simple, so awesome.

"It delivers low levels of infra-red light, which researchers [...] believe may stimulate the growth of brain cells. Tests in mice showed it improved learning ability and a study in humans is due to begin in the summer."

"... if sirtuin activators really do prevent cancer and heart disease and Alzheimer's and nearly everything else that causes our bodies and minds to fail, how much will it cost?" An important question.

"Britain's fertility regulator has decided in principle to allow scientists to create human-animal hybrid embryos for research purposes, as experts downplayed ethical concerns." Jolly good show.

"Is there any difference between repairing or removing a disability, as opposed to preventing one genetically?" Ethics come in many shades of grey.

"Modeled after an adult female and equipped with body parts that move in a smooth, human-like way, the android is designed to provide students with valuable hands-on experience in diagnosing rare medical conditions."

"A "virtual Iraq" simulation that allows soldiers to re-live and confront psychological trauma has produced promising results for the initial handful of patients treated using the system." Talk about counter-intuitive.
