1) Happiness is viral, thanks to social media

New research from the University of California in San Diego, and published in the journal PLOS One, suggests that happy status updates encourage happy updates from other users.
Previous studies have shown that emotion spreads among people in direct, person-to-person contact. This "emotional contagion" has been documented among friends, acquaintances, and even among strangers.
But how successfully this contagion is mediated through online relationships is less well known.
The researchers behind the new study analyzed over a billion anonymized status updates from more than 100 million Facebook users. The users were drawn from the top 10 most populous US cities, and their Facebook updating occurred during a period of 1,180 days between January 2009 and March 2012.
However, the researchers did not read any of these social media messages. Instead, they used a piece of software called [...]

2) Targeting molecular interaction of Marburg virus and host protein may arrest this lethal virus

A protein that normally protects cells from environmental stresses has been shown to interact with Marburg virus VP24, allowing the deadly Marburg virus to live longer and replicate better, according to a cell culture study led by scientists at the Icahn School of Medicine at Mount Sinai. The investigators say that deciphering the molecular details of how Marburg virus and the host protein interact may help in developing inhibitors of the virus. Results from the study are published online March 13 in the peer-reviewed journal Cell Reports.
Infections with Marburg virus lead to death in as many as 90% of those infected. Once restricted to Africa, cases of the virus have been identified in travelers from Europe and the United States, making effective prevention and treatment a top biodefense priority.
"Marburg virus has been essentially untreatable," said the study's senior author, [...]

3) Mood, sleep and quality of life improved by mindfulness-based meditation in teenagers with cancer

Mindfulness-based meditation could lessen some symptoms associated with cancer in teens, according to the results of a clinical trial intervention led by researchers at the University of Montreal and its affiliated CHU Sainte-Justine children's hospital. Mindfulness-based meditation focuses on the present moment and the connection between the mind and body. Adolescents living with cancer face not only the physical symptoms of their condition, but also the anxiety and uncertainty related to the progression of the disease, the anticipation of physical and emotional pain related to illness and treatment, the significant changes implied in living with cancer, as well as the fear of recurrence after remission. Catherine Malboeuf-Hurtubise of the university's Department of Psychology presented the findings at the American Psychosomatic Society Meeting in San Francisco.
The researchers asked [...]
