Maternal separation stresses the baby

New York, November 2, 2011 -- A woman goes into labor, and gives birth. The newborn is swaddled and placed to sleep in a nearby bassinet, or taken to the hospital nursery so that the mother can rest. Despite this common practice, new research published in Biological Psychiatry provides new evidence that separating infants from their mothers is stressful to the baby.

A hormone ensures its future

Much of the body's chemistry is controlled by the brain – from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the body. In the process, they discovered a surprising new role for the 'hormone of love,' showing that it helps to direct the development of this brain structure.

Unraveling Batten disease

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood. The findings may form the basis for a therapy for this disorder.

Humanities researchers and digital technologies: Building infrastructures for a new age

Europe's leading scientists have pledged to embrace and expand the role of technology in the Humanities. In a Science Policy Briefing released today by the European Science Foundation (ESF), they argue that without Research Infrastructures (RIs) such as archives, libraries, academies, museums and galleries, significant strands of Humanities research would not be possible. By drawing on a number of case studies, the report demonstrates that digital RIs offer Humanities scholars new and productive ways to explore old questions and develop new ones.

Study: A rich club in the human brain

BLOOMINGTON, Ind. -- Just as the Occupy Wall Street movement has brought more attention to financial disparities between the haves and have-nots in American society, researchers from Indiana University and the University Medical Center Utrecht in The Netherlands are highlighting the disproportionate influence of so called "Rich Clubs" within the human brain.

Not all regions of the brain, they say, are created equal.

Hippocampus plays bigger memory role than previously thought

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

Architecture and design help the brain to recover

How does the hospital environment affect our rehabilitation? New research from the University of Gothenburg, Sweden, into how the space around us affects the brain reveals that well-planned architecture, design and sensory stimulation increase patients' ability to recover both physically and mentally. Digital textiles and multisensory spaces can make rehabilitation more effective and reduce the amount of time spent in care.

More years to life and life to years through increased motivation for an active life

Regular physical activity is associated with a lower risk of suffering depression in old age. This is shown by one of the largest studies on elderly Europeans to have been carried out, by researchers at the University of Gothenburg, Sweden, among others. Research also shows that self-determined motivation and perceived competence are important factors in persuading elderly people to exercise more.

New drug shows promise against multiple sclerosis

An experimental drug called Ocrelizumab has shown promise in a Phase 2 clinical trial involving 220 people with multiple sclerosis (MS), an often debilitating, chronic autoimmune disease that affects an increasing number of people in North America. It usually strikes young adults and is more common in women than in men.

The study, carried out by researchers at the University of California, San Francisco (UCSF) Medical Center, and involving hospitals in the United States, Canada, and Europe, is described this week in the British medical journal Lancet.

People rationalize situations they're stuck with, but rebel when they think there's an out

People who feel like they're stuck with a rule or restriction are more likely to be content with it than people who think that the rule isn't definite. The authors of a new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, say this conclusion may help explain everything from unrequited love to the uprisings of the Arab Spring.

Switching senses

PASADENA, Calif.—Many meat-eating animals have unique ways of hunting down a meal using their senses. To find a tasty treat, bats use echolocation, snakes rely on infrared vision, and owls take advantage of the concave feathers on their faces, the better to help them hear possible prey. Leeches have not just one but two distinct ways of detecting dinner and, according to new findings from biologists at the California Institute of Technology (Caltech), their preferred method changes as they age.

Babies understand thought process of others at 10 months old, MU research finds

COLUMBIA, Mo. – New research from the University of Missouri indicates that at 10 months, babies start to understand another person's thought process, providing new insights on how humans acquire knowledge and how communication develops.

MIT: New algorithm could substantially speed up MRI scans

Magnetic resonance imaging (MRI) devices can scan the inside of the body in intricate detail, allowing clinicians to spot even the earliest signs of cancer or other abnormalities. But they can be a long and uncomfortable experience for patients, requiring them to lie still in the machine for up to 45 minutes.

Now this scan time could be cut to just 15 minutes, thanks to an algorithm developed at MIT's Research Laboratory of Electronics.

Researchers pinpoint possible new cause for unexplained miscarriages

TORONTO, ON., Nov. 1, 2011—Researchers at St. Michael's Hospital have identified a potential new cause for unexplained miscarriages in mice.

They also identified two possible treatments to prevent these miscarriages and their work has broader implications for the development of new drugs to treat heart attacks and strokes.

Could social media be used to detect disease outbreaks?

New research has looked at whether social media could be used to track an event or phenomenon, such as flu outbreaks and rainfall rates.

The study by academics at the University of Bristol's Intelligent Systems Laboratory is published online in ACM Transactions on Intelligent Systems and Technology.

Social networks, such as Facebook and microblogging services like Twitter, have only been around for a short time but in that time they have provided shapshots of real life by forming, electronically, public expression and interaction.
