Shiny new tool for imaging biomolecules Posted: 23 Mar 2012 05:55 PM PDT Researchers have developed a technique for lacing artificial membranes with billions of gold nanoantennas that can boost optical signals from a protein tens of thousands of times without the protein ever being touched. This technique could provide a critical tool in the fight against a wide range of health problems including cancer.

New epilepsy gene located in dogs Posted: 23 Mar 2012 05:53 PM PDT A new epilepsy gene for idiopathic epilepsy in Belgian Shepherds has been found in the canine chromosome 37. This research opens new avenues for the understanding of the genetic background of the most common canine epilepsies. The research also has an impact on the understanding of common epilepsies in humans.

'Bed-of-nails' breast implant deters cancer cells Posted: 23 Mar 2012 10:49 AM PDT Researchers have created an implant that appears to deter breast cancer cell regrowth. Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy breast cells.

Brain insulin resistance contributes to cognitive decline in Alzheimer's disease Posted: 23 Mar 2012 10:49 AM PDT Insulin resistance in the brain precedes and contributes to cognitive decline above and beyond other known causes of Alzheimer's disease, according to a new study.

Expectations, exhaustion can lead mothers to post-adoption stress Posted: 23 Mar 2012 10:49 AM PDT Fatigue and unrealistic expectations of parenthood may help contribute to post-adoption depression in women, according to a new study.

A new test might facilitate diagnosis and drug development for Alzheimer's disease Posted: 23 Mar 2012 10:46 AM PDT Scientists have developed a new method for measurement of aggregated beta-amyloid – a protein complex believed to cause major nerve cell damage and dysfunction in Alzheimer's disease. The new method might facilitate diagnosis and detection as well as development of drugs directed against aggregated beta-amyloid.

Who knew? Fruit flies get kidney stones too Posted: 23 Mar 2012 10:45 AM PDT Research on kidney stones in fruit flies may hold the key to developing a treatment that could someday stop the formation of kidney stones in humans, scientists have found.

Biomarkers for autism discovered Posted: 23 Mar 2012 10:45 AM PDT There are no acknowledged biomarkers for autism today. An important step towards developing a rapid, inexpensive diagnostic method for autism has now been take. Through advanced mass spectrometry the researchers managed to capture promising biomarkers from a tiny blood sample.

Humans began walking upright to carry scarce resources, chimp study suggests Posted: 23 Mar 2012 10:44 AM PDT Most of us walk and carry items in our hands every day. These are seemingly simple activities that the majority of us don't question. But scientists have discovered that human bipedalism, or walking upright, may have originated millions of years ago as an adaptation to carrying scarce, high-quality resources.

Exercise is not enough for sedentary workers Posted: 23 Mar 2012 06:38 AM PDT Good physical condition is a route to better health, and in order to improve it, exercising several days a week is recommended. Although it is possible to become healthier by exercising, long daily sedentary periods cause a health risk despite physical activity.

Gene expression abnormalities in autism identified Posted: 22 Mar 2012 09:13 PM PDT A new study has for the first time identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets that could lead to discoveries of new prevention strategies and treatment for the disorder.

How music helps prevent organ rejection Posted: 22 Mar 2012 09:12 PM PDT Music has a fundamental affect on humans. It can reduce stress, enhance relaxation, provide a distraction from pain, and improve the results of clinical therapy. New research demonstrates that music can reduce rejection of heart transplants in mice by influencing the immune system.
