Stress shared by same-sex couples can have unique health impacts

fre, 01/30/2015 - 19:28
Minority stress -- which results from being stigmatized and disadvantaged in society -- affects same-sex couples' stress levels and overall health, research indicates. Authors of a new study state that the health effects of minority stress shared by a couple can be understood as distinct from individual stress, a new framework in the field.

Fluorescent dyes 'light up' brain cancer cells

fre, 01/30/2015 - 18:16
Two new fluorescent dyes attracted to cancer cells may help neurosurgeons more accurately localize and completely resect brain tumors, suggests a new study. Removing all visible areas of cancer (gross total resection) significantly improves survival after brain cancer surgery.

Mobile and interactive media use by young children: The good, the bad and the unknown

fre, 01/30/2015 - 16:26
Mobile devices are everywhere and children are using them more frequently at young ages. The impact these mobile devices are having on the development and behavior of children is still relatively unknown. Researchers review the many types of interactive media available today and raise important questions regarding their use as educational tools, as well as their potential detrimental role in stunting the development of important tools for self-regulation.

Key discovery to preventing blindness, stroke devastation

fre, 01/30/2015 - 16:26
Gene interactions that determine whether cells live or die in such conditions as age-related macular degeneration and ischemic stroke have been discovered by researchers. These common molecular mechanisms in vision and brain integrity can prevent blindness and also promote recovery from a stroke.

Treating Cerebral Malaria: New Molecular Target Identified

fre, 01/30/2015 - 14:21
A drug already approved for treating other diseases may be useful as a treatment for cerebral malaria, according to researchers who discovered a novel link between food intake during the early stages of infection and the outcome of the disease, identifying two molecular pathways that could serve as new targets for treatment.

New technologies to help patients with Parkinson's disease

fre, 01/30/2015 - 14:15
New wearable sensor networks and mobile phone applications are being tested for their potential to monitor and manage patients with Parkinson’s disease. The research aim is the usage of low-cost wearable sensors that can continuously collect and process the accelerometry signals to automatically detect and quantify the symptoms of the patient. Once we this is done, the information is sent to hospital to generate a daily report that will alert the doctor in case of any outlier.

Heavy drinking in middle-age may increase stroke risk more than traditional factors

tor, 01/29/2015 - 23:03
Drinking more than two alcoholic beverages a day in middle-age raised stroke risks more than traditional factors such as high blood pressure and diabetes. Heavy drinking in mid-life was linked to having a stroke about five years earlier in life irrespective of genetic and early-life factors.

Is this the year you join the top one percent? Affluence more fluid than once thought

tor, 01/29/2015 - 22:09
Here's some good news for the New Year: According to new research, there's a 1 in 9 chance that a typical American will hit the jackpot and join the wealthiest 1 percent for at least one year in her or his working life. And now the bad news: That same research says only an elite few get to stay in that economic stratosphere -- and nonwhite workers remain among those who face far longer odds.

Complex environments push 'brain' evolution

tor, 01/29/2015 - 22:08
Little animations trying to master a computer game are teaching neuroscience researchers how the brain evolves when faced with difficult tasks. Neuroscientists have programmed animated critters that they call 'animats.' The critters have a rudimentary neural system made of eight nodes: two sensors, two motors, and four internal computers that coordinate sensation, movement and memory.

Privacy challenges: Just four vague pieces of info can identify you, and your credit card

tor, 01/29/2015 - 22:08
Just four fairly vague pieces of information -- the dates and locations of four purchases -- are enough to identify 90 percent of the people in a data set recording three months of credit-card transactions by 1.1 million users. If someone had copies of just three of your recent receipts -- or one receipt, one Instagram photo of you having coffee with friends, and one tweet about the phone you just bought -- would have a 94 percent chance of extracting your credit card records from those of a million other people. This is true, the researchers say, even in cases where no one in the data set is identified by name, address, credit card number, or anything else that we typically think of as personal information.

First-ever view of protein structure may lead to better anxiety drugs

tor, 01/29/2015 - 20:30
When new medicines are invented, the drug may hit the intended target and nullify the symptoms, but nailing a bull's eye -- one that produces zero side effects -- can be quite elusive. New research has, for the first time, revealed the crystal structure of a key protein, TSPO, which is associated with several forms of anxiety disorders.

New clues about a brain protein with high affinity for valium

tor, 01/29/2015 - 20:29
Valium, one of the best known antianxiety drugs, produces its calming effects by binding with a particular protein in the brain. But the drug has an almost equally strong affinity for a completely different protein. New studies revealing atomic level details of this secondary interaction might offer clues about Valium's side effects and point the way to more effective drugs.

Transgender kids show consistent gender identity across measures

tor, 01/29/2015 - 19:29
A study with 32 transgender children, ages 5 to 12, indicates that the gender identity of these children is deeply held and is not the result of confusion about gender identity or pretense. The study is one of the first to explore gender identity in transgender children using implicit measures that operate outside conscious awareness and are, therefore, less susceptible to modification than self-report measures.

Walking on ice takes more than brains: 'Mini-brain' in spinal cord aids in balance

tor, 01/29/2015 - 19:28
Scientists have discovered how a "mini-brain" in the spinal cord aids in balance. Much of the balancing act that our bodies perform when faced with a task such as walking on an icy surface happens unconsciously, thanks to a cluster of neurons in our spinal cord that function as a "mini-brain" to integrate sensory information and make the necessary adjustments to our muscles so that we don't slip and fall, researchers report.
