Researchers quantify muscle soreness Posted: 23 Jan 2012 02:57 PM PST Quantifying how sore a person is after a long workout is a challenge for doctors and researchers, but scientists think they may have figured it out.

Researchers develop gene therapy that could correct a common form of blindness Posted: 23 Jan 2012 01:34 PM PST A new gene therapy has the potential to treat a common form of blindness that strikes both youngsters and adults. The technique works by replacing a malfunctioning gene in the eye with a normal working copy that supplies a protein necessary for light-sensitive cells in the eye to function. Several complex steps remain before the gene therapy technique can be used in humans, but once at that stage, it has great potential to change lives.

Use of iodinated contrast media in imaging procedures appears to affect thyroid function Posted: 23 Jan 2012 01:33 PM PST Exposure to iodinated contrast media during imaging procedures is associated with changes in thyroid function, and increased risk of developing hyperthyroidism, according to a new report.

Lifelong brain-stimulating habits linked to lower Alzheimer's protein levels Posted: 23 Jan 2012 01:33 PM PST People who have made mental engagement a lifelong habit have lower levels of a key protein linked to Alzheimer's disease, according to a new study by neuroscientists. The findings could provide support for cognitive therapies to help prevent the onset of a debilitating disease.

Magic mushrooms' effects illuminated in brain imaging studies Posted: 23 Jan 2012 12:20 PM PST Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two new studies identify areas of the brain where activity is suppressed by psilocybin and suggest that it helps people to experience memories more vividly.

Nurturing mothers rear physically healthier adults Posted: 23 Jan 2012 09:39 AM PST Nurturing mothers have garnered accolades for rescuing skinned knees on the playground and coaxing their children to sleep with lullabies. Now they're gaining merit for their offspring's physical health in middle age. While children raised in families with low socioeconomic status frequently go on to have high rates of chronic illness in adulthood, a sizable minority remain healthy across the life course, new research shows.

Compounds in mate tea induce death in colon cancer cells, in vitro study shows Posted: 23 Jan 2012 08:55 AM PST In a recent study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of mate tea, which has long been consumed in South America for its medicinal properties.

Easier testing for diabetics? Biochip measures glucose in saliva, not blood Posted: 23 Jan 2012 08:55 AM PST Engineers have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances.

Patterns of chromosome abnormality: The key to cancer? Posted: 23 Jan 2012 08:55 AM PST Researchers have combined techniques from computer science and statistics to discover that many chromosomal pairs are lost or gained together across various cancer types, such as kidney, skeleton, and liver cancers. Tracking these changes, he says, could aid our understanding of the driving forces of cancer's progress.

Women report feeling pain more intensely than men, says study of electronic medical records Posted: 23 Jan 2012 08:55 AM PST Women report more intense pain than men in virtually every disease category, according to researchers who mined a huge collection of electronic medical records to establish the broad gender difference to a high level of statistical significance.

Molecular fingerprint discovered that may improve outcomes for head and neck cancer patients Posted: 23 Jan 2012 08:42 AM PST Researchers have found a biomarker in head and neck cancers that can predict whether a patient's tumor will be life threatening. The biomarker is considered particularly promising because it can detect the level of risk immediately following diagnosis.

Genes and timing of menopause Posted: 23 Jan 2012 06:47 AM PST Researchers have discovered 13 new regions of the genome associated with the timing of menopause. These genes shed light on the biological pathways involved in reproductive lifespan and will provide insights into conditions connected to menopause, such as breast cancer and heart disease.

Homeless heavy drinkers imbibe less when housing allows alcohol Posted: 19 Jan 2012 01:32 PM PST A study of a controversial housing project that allows chronically homeless people with severe alcohol problems to drink in their apartments found that during their first two years in the building residents cut their heavy drinking by 35 percent.

Benefits of high quality child care persist 30 years later Posted: 19 Jan 2012 10:37 AM PST Adults who participated in a high quality early childhood education program in the 1970s are still benefiting from their early experiences in a variety of ways, according to a new study.

Study pinpoints and plugs mechanism of AML cancer cell escape Posted: 18 Jan 2012 01:51 PM PST Turning off the gene that codes for WEE1 sensitizes acute myeloid leukemia cells to chemotherapy, a new study shows.
