Synthetic Biology: Gene Therapy Gets Under The Skin Posted: 29 Jun 2009 02:00 AM PDT Vaseline, a known molecule from apples and a gene network encapsulated in algal gelatin are the components of a possible gene therapy which literally gets under the skin. An important part in this is played by phloretin, an antioxidant found in apples which makes cell walls more permeable and is used in cosmetics as an anti-wrinkle agent.

Lean Mass Better For Developing Bones In Young People Posted: 29 Jun 2009 02:00 AM PDT New research shows that a child with leaner body mass, or muscle, builds bigger bones than a child who weighs the same but has a greater percentage of fat.

Can A Little Extra Weight Protect People From Early Death? Underweight, Extremely Obese Die Earlier Than People Of Normal Weight Posted: 29 Jun 2009 02:00 AM PDT Underweight people and those who are extremely obese die earlier than people of normal weight -- but those who are overweight actually live longer than people of normal weight. Those are the findings of a new study.

Blood Flow In Alzheimer's Disease Posted: 29 Jun 2009 02:00 AM PDT Scientists have discovered that endothelin converting enzyme-2 (ECE-2) may cause the decrease in cerebral blood flow seen in Alzheimer's disease.

Fly Larvae Shun The Light Posted: 29 Jun 2009 02:00 AM PDT Drosophila larvae avoid light during the foraging stage of their development. New research shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior.

Intensive In-hospital Support Doubles Likelihood Of Smoking Cessation In Heart Patients Posted: 29 Jun 2009 02:00 AM PDT Patients admitted to hospital with coronary artery disease are twice as likely to quit smoking after receiving intensive smoking cessation support compared to minimal support, found a new study.

Nematode Courting Caught On Camera Posted: 28 Jun 2009 11:00 PM PDT Researchers studying the nervous control of nematode mating behavior have produced video footage of a male worm preparing to mate with a hermaphrodite.
