Reactions to everyday stressors predict future health Posted: 02 Nov 2012 05:51 PM PDT Contrary to popular perception, stressors don't cause health problems -- it's people's reactions to the stressors that determine whether they will suffer health consequences, according to new research.

In-sync brain waves hold memory of objects just seen Posted: 02 Nov 2012 05:51 PM PDT The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study suggests. The more in-sync such electrical signals of neurons were in two key hubs of the circuit, the more those cells held the short-term memory of a just-seen object. The work demonstrates, for the first time, that there is information about short term memories reflected in in-sync brainwaves.

Brain imaging alone cannot diagnose autism Posted: 02 Nov 2012 12:20 PM PDT Experts caution against heralding the use of brain imaging scans to diagnose autism and urges greater focus on conducting large, long-term multicenter studies to identify the biological basis of the disorder.

Alcohol, drug abuse counselors don't always require total abstinence Posted: 02 Nov 2012 12:19 PM PDT Compared to a survey conducted nearly 20 years ago, about twice the proportion of addiction counselors now find it acceptable for at least some of their patients to have a drink occasionally -- either as an intermediate goal or as their final treatment goal, according to a new study.

Difficult-to-read font reduces political polarity, study finds Posted: 02 Nov 2012 12:19 PM PDT Liberals and conservatives who are polarized on certain politically charged subjects become more moderate when reading political arguments in a difficult-to-read font, researchers report in a new study. Likewise, people with induced bias for or against a defendant in a mock trial are less likely to act on that bias if they have to struggle to read the evidence against him.

New medication shows promise as lipid-lowering therapy for rare cholesterol disorder Posted: 02 Nov 2012 08:54 AM PDT An international effort has resulted in positive phase 3 clinical trial results for a new medicine to treat patients suffering from a rare and deadly cholesterol disorder, homozygous familial hypercholesterolemia.

Confident beginning key to happy marriage: Don't ignore doubts, experts warn Posted: 02 Nov 2012 08:53 AM PDT Couples about to tie the knot shouldn't ignore nagging doubts about getting married, warns a researcher.

New finding gives clues for overcoming tamoxifen-resistant breast cancer Posted: 02 Nov 2012 08:53 AM PDT A cancer biology team reports breakthrough findings about specific cellular mechanisms that may help overcome endocrine (hormone) therapy-resistance in patients with estrogen-positive breast cancers, combating a widespread problem in effective medical management of the disease. The team has identified a specific estrogen receptor co-activator -- known as MED1 -- as playing a central role in mediating tamoxifen resistance in human breast cancer.

When considering bariatric surgery, think about bones Posted: 02 Nov 2012 08:53 AM PDT Bariatric surgery, which significantly curtails the amount of food a person can eat, is the most effective treatment against obesity and is being recognized as a potentially valuable tool in the fight against diabetes related to obesity. It is being performed on increasing numbers of people worldwide, including teenagers. Unfortunately, some types of bariatric surgery may also cause bone loss, a cause for concern, particularly when carried out on young people who have not yet reached their peak bone mass, say endocrinologists who have just published a new review.

Tumor-causing cells are squishier Posted: 02 Nov 2012 08:51 AM PDT A new tool developed by scientists separates tumor-causing cancer cells from more benign cells by subjecting the cells to a microscopic game of Plinko -- except only the squishiest cells make it through.

'New beginning' in split-brain research, using new analytical tools Posted: 02 Nov 2012 06:20 AM PDT Scientists have reported an important discovery in the interdisciplinary study of split-brain research. The findings uncover dynamic changes in brain coordination patterns between left and right hemispheres.

MRI research sheds new light on nerve fibres in the brain Posted: 02 Nov 2012 05:46 AM PDT Experts in magnetic resonance imaging from the UK have made a key discovery which could give the medical world a new tool for the improved diagnosis and monitoring of brain diseases like multiple sclerosis.

Cannabis use mimics cognitive weakness that can lead to schizophrenia, fMRI study finds Posted: 02 Nov 2012 05:46 AM PDT Researchers in Norway have found new support for their theory that cannabis use causes a temporary cognitive breakdown in non-psychotic individuals, leading to long-term psychosis. In an fMRI study, researchers found a different brain activity pattern in schizophrenia patients with previous cannabis use than in schizophrenic patients without prior cannabis use.
