Comet Pan-STARRS marches across the sky Posted: 06 Jul 2014 02:18 PM PDT NASA's NEOWISE mission captured a series of pictures of comet C/2012 K1 -- also known as comet Pan-STARRS -- as it swept across our skies in May 2014. The comet is named after the astronomical survey project called the Panoramic Survey Telescope and Rapid Response System in Hawaii, which discovered the icy visitor in May 2012.

Rewriting the history of volcanic forcing during the past 2,000 years Posted: 06 Jul 2014 12:33 PM PDT Scientists have completed the most accurate and precise reconstruction to date of historic volcanic sulfate emissions in the Southern Hemisphere. The new record is derived from a large number of individual ice cores collected at locations across Antarctica and is the first annually resolved record extending through the Common Era.

Does depression require hospitalization? Posted: 06 Jul 2014 05:39 AM PDT A new study has analyzed the difference between day hospital and inpatient stay in depression. Depending on the severity of depression, patients may be treated at different levels of care with psychotherapy and/or antidepressant medication. While several previous studies compared the efficacy of different levels of care for psychotherapy of personality disorders, sufficient data is lacking for the comparison of day-clinic and inpatient psychotherapy for depression. The current pilot study evaluates the feasibility of randomization in a routine hospital setting and compares preliminary efficacy for day-clinic and inpatient psychotherapy for depression.

The long-term effects of psychotherapy on borderline personality disorder Posted: 06 Jul 2014 05:39 AM PDT A new study has analyzed the long-term effects of psychotherapy on borderline personality disorder. Authors report the effect of DBT compared to TAU on inpatient service use, and a follow-up 6 months after the end of treatment.

Personality and heart attacks: A new look Posted: 06 Jul 2014 05:39 AM PDT A new study has addressed the relationship between personality and heart attacks. Distressed (type D) personality (TDP), characterized by high negative affectivity (NA) and social inhibition (SI), along with depression, anxiety and other negative affects (such as demoralization, hopelessness, pessimism and rumination) have been implicated as potential risk factors for coronary artery disease. While some evidence suggests that the NA dimension of TDP overlaps at least partially with depression, other studies underline how 'TDP refers to a chronic, more covert form of distress that is distinct from depression'.

Temperament may contribute to cardiac complications in high blood pressure Posted: 06 Jul 2014 05:39 AM PDT Temperament has been traditionally associated with high blood pressure. A new study has substantiated this issue. Major depression and coronary heart disease have a strong, bidirectional relationship.

New treatment for borderline personality disorder Posted: 06 Jul 2014 05:39 AM PDT A group of Swiss investigators reports on a new type of psychotherapy for borderline personality disorder.

First evidence for painless atrial fibrillation treatment Posted: 04 Jul 2014 10:48 AM PDT Scientists have the first evidence for a shockless treatment for atrial fibrillation. For the current study, the researchers devised a method of shockless defibrillation. They used optogenetics to genetically insert depolarising ion channels into the heart that can be activated by light.

A dominant hemisphere for handedness and language? Posted: 04 Jul 2014 10:46 AM PDT Through an innovative approach using a large psychometric and brain imaging database, researchers have demonstrated that the location of language areas in the brain is independent of left- or right-handedness, except for a very small proportion of left-handed individuals whose right hemisphere is dominant for both manual work and language.

Size of the human genome reduced to 19,000 genes Posted: 03 Jul 2014 08:28 AM PDT A new study updates the number of human genes to 19,000; 1,700 fewer than the genes in the most recent annotation, and well below the initial estimations of 100,000 genes. The work concludes that almost all of these genes have ancestors prior to the appearance of primates 50 million years ago.
