Many gene tests a waste of money, experts say

LONDON (Reuters) - Genetic tests to assess disease risk are proliferating but many are a waste of money and tell people little more than they would know from studying family history, medical experts said on Friday.
WHO concerned at new Ebola strain

Abundant Evidence to Warn People Against GE Crops
November 30, 2007 08:25 AM -
There are thousands of toxic or allergic-type reactions in humans, thousands of sick, sterile, and dead livestock, and damage to virtually every organ and system studied in lab animals. Government safety assessments, including those of Food Standards Australia New Zealand (FSANZ), do not identify many of the dangers, and analysis reveals that industry studies submitted to FSANZ are designed to avoid finding them.
New strain of Ebola identified

Analysis of samples taken from some of the victims show it is a previously unknown type of Ebola, a team at the U.S. Centers for Disease Control and Prevention said.
Brain abnormalities mapped in autistic children
November 29, 2007 09:50 AM - Reuters
Autistic children have more gray matter in areas of the brain that control social processing and sight-based learning than children without the developmental disability, a small study said on Wednesday.
Researchers combined two sophisticated imaging techniques to track the motion of water molecules in the brain and pinpoint small changes in gray matter volume in 13 boys with high-functioning autism or Asperger syndrome and 12 healthy adolescents. Their average age was 11.
Manure Management Reduces Levels of Antibiotics and Antibiotic Resistance Genes
November 29, 2007 08:36 AM - American Society of Agronomy
Antibiotic resistance is a growing human health concern. Researchers around the globe have found antibiotics and other pharmaceuticals to be present in surface waters and sediments, municipal wastewater, animal manure lagoons, and underlying groundwater. In a recent article in the November-December issue of Journal of Environmental Quality, researchers at Colorado State University (CSU) describe a study to find out if animal waste contributes to the spread of antibiotics and antibiotic resistance genes (ARG), and if they can be reduced by appropriate manure management practices.
Researcher develops realistic cancer growth models
November 29, 2007 08:17 AM - Anne Ju -Cornell Chronicle
Scientists can only develop new cancer drugs or search for cures by testing their theories on the real thing. Traditionally, they've done so by culturing cancer cells on petri dishes or plastic slides. But those cancer cells do not behave the way they do in the body. They only partially re-create the aggressive behavior of tumors in real patients.
That is the problem that drives Claudia Fischbach-Teschl, Cornell assistant professor of biomedical engineering, whose lab creates realistic experimental tumor models, which may then lead to better drug therapies or even a cure.
Wild birds not ruled out as UK bird flu source

It also said no evidence had been found so far that infected poultry or poultry products may have been the cause.
HIV/AIDS discrimination widespread in China: U.N.
November 28, 2007 05:49 AM - Reuters
Subinay Nandy, China country director for the U.N. Development Programme, said China had done a "tremendous job" implementing anti-HIV/AIDS discrimination policies and legislation but enduring misconceptions were stopping sufferers from seeking treatment.
Cancer-resistant mouse discovered
November 27, 2007 08:55 AM - University of Kentucky
A mouse resistant to cancer, even highly-aggressive types, has been created by researchers at the University of Kentucky. The breakthrough stems from a discovery by UK College of Medicine professor of radiation medicine Vivek Rangnekar and a team of researchers who found a tumor-suppressor gene called "Par-4" in the prostate.
The researchers discovered that the Par-4 gene kills cancer cells, but not normal cells. There are very few molecules that specifically fight against cancer cells, giving it a potentially therapeutic application.
