Moral evaluations of harm are instant and emotional Posted: 28 Nov 2012 03:27 PM PST People are able to detect, within a split second, if a hurtful action they are witnessing is intentional or accidental, new research on the brain shows. The study is the first to explain how the brain is hard-wired to recognize when another person is being intentionally harmed.

Mediation combined with art therapy can change your brain and lower anxiety Posted: 28 Nov 2012 03:27 PM PST Cancer and stress go hand-in-hand, and high stress levels can lead to poorer health outcomes in cancer patients.

Ponatinib acts against the most resistant types of chronic myeloid leukemia Posted: 28 Nov 2012 03:27 PM PST Phase I trial shows third-generation drug helps patients after other treatments fail.

Moral judgments quicker, more extreme than practical ones, but also flexible Posted: 28 Nov 2012 03:27 PM PST Judgments we make with a moral underpinning are made more quickly and are more extreme than those same judgments based on practical considerations, a new set of studies finds. However, the findings also show that judgments based on morality can be readily shifted and made with other considerations in mind.

Order of psychiatric diagnoses may influence how clinicians identify symptoms Posted: 28 Nov 2012 01:22 PM PST The diagnostic system used by many mental health practitioners in the United States assumes that symptoms of two disorders that occur at the same time are additive and that the order in which the disorders are presented doesn't matter.

Double duty: Immune system regulator found to protect brain from effects of stroke Posted: 28 Nov 2012 11:35 AM PST A small molecule known to regulate white blood cells has a surprising second role in protecting brain cells from the deleterious effects of stroke, researchers report. The molecule, microRNA-223, affects how cells respond to the temporary loss of blood supply brought on by stroke -- and thus the cells' likelihood of suffering permanent damage.

Analysis of conflicting fish oil studies finds that omega-3 fatty acids still matter Posted: 28 Nov 2012 11:35 AM PST A new analysis helps to sort through conflicting findings from literally hundreds of studies on use of omega-3 fatty acids for heart disease. It concludes that they still matter; they do work; and that modern therapies for cardiovascular disease help to mask the benefits omega-3 consumption might otherwise provide.

New light shed on virus associated with developmental delays and deafness Posted: 28 Nov 2012 11:35 AM PST A new study reveals that primitive human stem cells are resistant to human cytomegalovirus (HCMV), one of the leading prenatal causes of congenital intellectual disability, deafness and deformities worldwide.

Young adults more likely to smoke cannabis than drink before driving, survey of Canadians shows Posted: 28 Nov 2012 08:21 AM PST Most adults are drinking responsibly, and fewer are smoking or using illicit substances -- but several areas of concern were found in a 2011 recent survey.

Family's economic situation influences brain function in children Posted: 28 Nov 2012 07:39 AM PST Children of low socioeconomic status work harder to filter out irrelevant environmental information than those from a high-income background because of learned differences in what they pay attention to, according to new research.

Four is the 'magic' number Posted: 28 Nov 2012 06:39 AM PST According to psychological lore, when it comes to items of information the mind can cope with before confusion sets in, the "magic" number is seven. But a new analysis challenges this long-held view, suggesting the number might actually be four.

Immune system could play a central role in age-related macular degeneration Posted: 28 Nov 2012 06:39 AM PST Changes in how genes in the immune system function may result in age-related macular degeneration (AMD), the leading cause of visual impairment in older adults. The findings are epigenetic in nature, meaning that the underlying DNA is normal but gene expression has been modified, likely by environmental factors, in an adverse way. Environmental factors associated with AMD include smoking, diet, and aging. This is the first epigenetic study revealing the molecular mechanisms for any eye disease.

Malaria study suggests drugs should target female parasites Posted: 28 Nov 2012 06:39 AM PST Fresh insight into the parasite that causes malaria suggests a new way to develop drugs and vaccines to tackle the disease.
