Playing RFID tag with sheets of paper
06-Feb-12
Researchers in France have developed a way to deposit a thin aluminum RFID tag onto paper that not only reduces the amount of metal needed for the tag, and so the cost, but could open up RFID tagging to many more systems, even allowing a single printed sheet or flyer to be tagged.
Low levels of lipid antibodies increase complications following heart attack
06-Feb-12
Coronary patients with low levels of an immune system antibody called anti-PC, which neutralizes parts of the "bad" cholesterol, run a greater risk of suffering complications following an acute cardiac episode and thus of premature death.
East views the world differently to West
06-Feb-12
Cultural differences between the West and East are well documented, but a study shows that concrete differences also exist in how British and Chinese people recognize people and the world around them. Easterners really do look at the world differently to Westerners, according to new research.
Combined approach to global health has benefits
06-Feb-12
A new analysis demonstrates that confronting several diseases at once is a viable way to make the most of thinly stretched donor dollars and national health care budgets, and help save more lives.
Engineers weld nanowires with light
06-Feb-12
At the nano level, researchers have discovered a new way to weld together meshes of tiny wires. Their work could lead to exciting new electronics and solar applications. To succeed, they called upon plasmonics.
Children hospitalized at alarming rate due to abuse
06-Feb-12
In one year alone, over 4,500 children in the United States were hospitalized due to child abuse, and 300 of them died of their injuries, researchers report in a new study.
Positive parenting during early childhood may prevent obesity
06-Feb-12
Programs that support parents during their child’s early years hold promise for obesity prevention, according to a new study.
Did your surgeons miss something? New system to prevent retained surgical items
06-Feb-12
It may sound like something from a TV medical drama, but the incidence of surgeons leaving something behind in the body is very real at hospitals across the country. But researchers have now created a new system using state-of-the-art technologies to insure that no foreign objects are left behind during surgery.
Key to immune cell's 'internal guidance' system discovered
05-Feb-12
Researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, viruses and bacteria, and lead to more efficient vaccines.
Genetic variant increases risk of common type stroke
05-Feb-12
A genetic variant that increases the risk of a common type of stroke has been identified by scientists. This is one of the few genetic variants to date to be associated with risk of stroke and the discovery opens up new possibilities for treatment.
Early study suggests nanodiamonds safe for implants
05-Feb-12
As the number of knee and hip joint replacements grows, nanodiamond coatings could answer problems related to metal surfaces.
Hearing metaphors activates brain regions involved in sensory experience
03-Feb-12
New brain imaging research reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard.
Whole exome sequencing identifies cause of metabolic disease
03-Feb-12
Sequencing a patient's entire genome to discover the source of his or her disease is not routine, but geneticists are getting close. A case report shows how researchers can combine a simple blood test with an "executive summary" scan of the genome to diagnose a severe glycosylation disorder.
Why do cells age? Discovery of extremely long-lived proteins may provide insight into cell aging and neurodegenerative diseases
03-Feb-12
One of the big mysteries in biology is why cells age. Now scientists report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.
A lonely heart can make you sick: Middle aged divorced women vulnerable to contracting HIV
03-Feb-12
Newly divorced middle aged women are more vulnerable to contract HIV and other sexually transmitted diseases, according to new research, because they tend to let their guard down with new sexual partners and avoid using protection since they are not afraid of getting pregnant.
Regular use of vitamin and mineral supplements could reduce the risk of colon cancer, study suggests
03-Feb-12
Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.
The complex relationship between memory and silence
03-Feb-12
People who suffer a traumatic experience often don't talk about it, and many forget it over time. But not talking about something doesn't always mean you'll forget it; if you try to force yourself not to think about white bears, soon you'll be imagining polar bears doing the polka. A group of psychological scientists explore the relationship between silence and memories.
Schooling protects refugee children from disease
03-Feb-12
Refugee children have scant access to medical care and are particularly vulnerable to disease. Fresh research results show that just a few hours of schooling a week may have a pronounced positive impact on their health not only in childhood but later in life when they achieve adulthood.
Placebos and distraction: New study shows how to boost the power of pain relief, without drugs
03-Feb-12
Placebos reduce pain by creating an expectation of relief. Distraction -- say, doing a puzzle -- relieves it by keeping the brain busy. But do they use the same brain processes? Neuromaging suggests they do. When applying a placebo, scientists see activity in the dorsolateral prefrontal cortex. That's the part of the brain that controls high-level cognitive functions like working memory and attention -- which is what you use to do that distracting puzzle.
High-precision map of Milky Way's magnetic fields charted
03-Feb-12
Scientists have pooled their radio observations into a database, producing the highest precision map to date of the magnetic field within our own Milky Way galaxy.
