Research suggests that a common mechanism may underlie a variety of protein folding diseases

Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease.

Advancing knowledge of diet-gene interactions

Josi Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University joined more than eighty other leading researchers in the fields of nutrition and genetics to co-author a report outlining their strategy for maximizing the impact of nutrigenomics research on global poverty and health.

Reading problems and behavior problems in boys are intertwined

It's been known for more than a decade that children with reading problems, particularly boys, also tend to have behavior problems, and vice versa. The reason behind the connection, however, remained unclear.

Hormone aldosterone linked to quality of hearing

Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is.

Mystery of cot death may be explained

A failure to 'gasp' has long been proposed as the basis for sudden infant death syndrome, or cot death. A team at the University of Bristol has discovered a subset of cells in the brain that have the ability to self-generate nervous impulses, which appear essential for gasping. These cells have been termed 'pacemakers'.

Brain scans may detect neurological decline in normal people

Brain scans may detect neurological changes in people who exhibit no outward signs of cognitive decline but who later develop dementia or mental impairment, according to the results of a new study led by researchers at the University of California, Berkeley.

Anti-malarials most effective in lupus patients genetically at risk of high levels of TNF-alpha

Anti-malarial drugs are most effective in people with lupus who are genetically predisposed to high levels of tumour necrosis factor alpha and low levels of the cytokine IL-10.

Less is more hypothesis - gene loss may explain unique human traits

Humans and chimps share most of their genes, yet they differ dramatically in many ways - their walk, the sizes of their brains and their capacities for speech and language, for example.

Causes of type 1 diabetes

Scientists are casting a wide, tightly woven net with the goal of catching the causes of type 1 diabetes.

A new way of recognising DNA

Scientists led by Mike Hannon at the University of Birmingham and Miquel Coll at the Spanish Research Council in Barcelona have discovered a new way that drugs can attach themselves to DNA, which is a crucial step forward for researchers who are developing drugs to combat cancer and other diseases.

Stem cell injections may help those with severe peripheral artery disease

Indiana University School of Medicine scientists have begun a unique clinical trial using stem cell injections as a treatment that could offer hope to tens of thousands of people who face sores, ulcers and even amputations due to severe peripheral artery disease.

Soya products, beans and sunflower seeds reduce risk of contracting prostate cancer

Men who have a diet rich in soya products, beans and sunflower seeds run a much lower risk of contracting prostate cancer. New findings from Karolinska Institutet show that foods rich in phytoestrogens - plant-produced oestrogens - protect against the most common form of cancer in the western world.

Risk of Alzheimer's 80% genetic

In the largest twin study to date, researchers in the U.S. looked at the Swedish Twin Registry to see which factors lead to Alzheimer's disease (AD).

Grants bring Mesothelioma research to over $3 million

The Mesothelioma Applied Research Foundation has announced thrilling news for all who care about eradicating the vicious disease. MARF has awarded nine new grants of $100,000 each for exciting research projects commencing in late 2005 aimed at curing mesothelioma ("meso").

Gene mutation discovered that causes a rare form of Charcot-Marie-Tooth disease

A multi-national research team that includes a Saint Louis University neurologist has discovered a gene mutation that causes a rare form of Charcot-Marie-Tooth disease, an inherited progressive nerve disorder. The findings are published in an advance online issue of Nature Genetics

Common genetic variation increases SIDS risk in African Americans

About five percent of deaths from SIDS (sudden infant death syndrome) in African Americans can be traced to defects in one gene and half of those deaths result from a common genetic variation that increases an infant's risk of developing an abnormal heart rhythm during times of environmental stress

Chink in cancer's armor

Much as the famed starship Enterprise would deploy a deflector shield to evade enemy attack, tumor cells are capable of switching on a molecular force field of their own to fend off treatments aimed at killing them. Now University of Florida researchers have found a chink in their armor.

New technology could replace time-intensive urine specimens

For the millions of people who suffer from urinary tract infections each year and the doctors who treat them, a promising new biosensor technology has been developed that may replace antiquated testing methods and save precious health care dollars.

Duke University biologists evolve complex trait in the laboratory

Duke University biologists have evolved a complex trait in the laboratory -- using the pressure of selection to induce tobacco hornworms to evolve the dual trait of turning black or green depending on the temperature during their development.

NogoReceptor reduces Alzheimer's plaque

Increasing the level of a protein that plays a key role in traumatic spinal cord injuries and multiple sclerosis reduces the concentration of disease-causing plaque in Alzheimer's disease, Yale School of Medicine researchers report in the Journal of Neuroscience.
