Researchers discover link between a gene, lack of folate and colon cancer risk in mice
Cornell researchers report that they have identified a gene that increases the risk for colon cancer in laboratory mice when their diets lack folate. Colorectal cancer is the second leading cause of cancer-related deaths in the United States. More than 50,000 people die each year in this country from colon cancer, many due to a lack of early detection.

A jog a day keeps osteoporosis away
A jog a day keeps osteoporosis away
A short burst of vigorous physical activity like running and jogging is important for building bones in children, whereas more gentle exercise like walking, even for a longer period, has little effect. This suggests that while current recommendations on exercise aim to combat obesity and heart disease by promoting walking, these are unlikely to offer much protection against the risk of osteoporosis in later life.

$4M grant to explore plant-pathogen 'cat and mouse' games
$4M grant to explore plant-pathogen ’cat and mouse’ games
The arms race between plants and pathogens prompts both to evolve: Pathogens continually find new strategies to infect plants, and plants counter by foiling those strategies. Now, Cornell and Boyce Thompson Institute (BTI) researchers have received a $4 million National Science Foundation Plant Genome Research Program grant to explore plant-pathogen interactions in order to create more resistant crops.

Acupuncture is equally effective with simulated needles
[NEWS 24 March 2011] Simulated acupuncture - sometimes referred to as placebo - is just as beneficial as real acupuncture for treating nausea in cancer patients undergoing radiotherapy, according to a study from Karolinska Institutet and Linköping University in Sweden. Patients, who received only standard care including medications for nausea, felt significant more nausea than patients in both the acupuncture groups.

Epigenomic findings illuminate veiled variants
Genes make up only a tiny percentage of the human genome. The rest, which has remained measurable but mysterious, may hold vital clues about the genetic origins of disease. Using a new mapping strategy, a collaborative team led by researchers at the Broad Institute of MIT and Harvard, Massachusetts General Hospital (MGH), and MIT has begun to assign meaning to the regions beyond our genes and has revealed how minute changes in these regions might be connected to common diseases.

Do pre-conceived expectations impact on doctor analysis of X-rays?
Do pre-conceived expectations impact on doctor analysis of X-rays?
Scientists have long suspected that clinicians' ability to read X-rays can be skewed according to what they expect to find, but a University of Sydney study published this month in the international journal Radiology did not find evidence to support this theory. Lead author Warren Reed from the Faculty of Health Sciences put 22 highly experienced radiologists from the American Board of Radiologists to the test by studying the impact of prevalence expectation on the ability of the radiologists to detect pulmonary nodular lesions, or lung cancer.

Call for a better policy vision for hearing and sight impaired
Preliminary results from a University of Sydney study have shown up to 80 percent of people presenting to an eye clinic for vision loss assessment also have mild or moderate hearing loss. "The study highlights the potential for improved health services for the elderly, such as one-stop shops for screening both hearing and vision - services currently funded and offered separately in Australia," said researcher Dr Julie Schneider, from the Menzies Centre for Health Policy.

Malaria mosquitoes evolve differently to ward off pathogens
Malaria mosquitoes evolve differently to ward off pathogens
In analyzing malaria mosquitoes in sub-Saharan Africa, a Cornell-led team of researchers finds evidence of two very different evolutionary paths in the immune systems of neighboring mosquito groups. Genes in animal immune systems may evolve in one of two main ways in the constant fight against pathogens: They may evolve diverse forms of genes (alleles) to fight a wide variety of pathogens, or when only a few pathogens dominate, they may evolve one or a few alleles that specialize against common infections.

New method delivers Alzheimer's drug to the brain
New method delivers Alzheimer’s drug to the brain
Science | Health 21 Mar 11 Oxford University scientists have developed a new method for delivering complex drugs directly to the brain, a necessary step for treating diseases like Alzheimer's, Parkinson's, Motor Neuron Disease and Muscular Dystrophy. These diseases have largely resisted attempts to over the last 50 years develop new treatments, partly because of the difficulty of getting effective new drugs to the brain to slow or halt disease progression.
