Caloric restriction appears to prevent primary aging in the heart
Eating a very low-calorie yet nutritionally balanced diet is good for your heart. Studying heart function in members of an organization called the Caloric Restriction Society, investigators at Washington University School of Medicine in St. Louis found that their hearts functioned like the hearts of much younger people.
Comedy films boost blood flow to the heart
Watching comedy films boosts blood flow to the heart, finds a small study in the journal Heart.
Tickling ourselves is no laughing matter
Anticipating our own touch - for example in tickling oneself - reduces its impact, says Queen's psychologist Dr. Randy Flanagan, a member of the university's Centre for Neuroscience Studies. This is evidence of an important human adaptation that helps us interact with objects in our environment.
First impressions of beauty may demonstrate why the pretty prosper
We might not be able to resist a pretty face after all, according to a report from the University of Pennsylvania. Experiments in which subjects were given a fraction of a second to judge "attractiveness" offered further evidence that our preference for beauty might be hard-wired. People who participated in the studies were also more likely to associate pretty faces with positive traits.
Mobile phone use not linked to increased risk of glioma brain tumours
Mobile phones are not associated with an increased risk of the most common type of brain tumour, finds the first UK study of the relationship between mobile phone use and risk of glioma.
Heart-healthy compound in chocolate identified
In a multifaceted study involving the Kuna Indians of Panama, an international team of scientists has pinpointed a chemical compound that is, in part, responsible, for the heart-healthy benefits of certain cocoas and some chocolate products.
Commonly used antidepressants may also affect human immune system
Drugs that treat depression by manipulating the neurotransmitter serotonin in the brain may also affect the user's immune system in ways that are not yet understood, say scientists from Georgetown University Medical Center and a Canadian research institute.
Typhoid fever led to the fall of athens
Scientists have for many years debated the cause of the Plague of Athens. Analysis carried out by Manolis Papagrigorakis and colleagues using DNA collected from teeth from an ancient Greek burial pit points to typhoid fever as the disease responsible for this devastating epidemic.
Cause of ongoing pain discovered
New research shows that it is undamaged nerve fibres that cause ongoing spontaneous pain, not those that are injured.
Internet game provides breakthrough in predicting the spread of epidemics
Using a popular internet game that traces the travels of dollar bills, scientists have unveiled statistical laws of human travel in the United States, and developed a mathematical description that can be used to model the spread of infectious disease in this country. This model is considered a breakthrough in the field.

Use your brain, halve your risk of dementia
Research from UNSW provides the most convincing evidence to date that complex mental activity across people's lives significantly reduces the risk of dementia. The researchers found that such activity almost halves the incidence of dementia.
'To be or, or … um … line!'
"How do you learn all those lines?" It is the question most asked of actors and their art. The ability to remember and effortlessly deliver large quantities of dialogue verbatim amazes non-thespians. Most people imagine that learning a script involves hours, days, and even months of rote memorization. But actors seldom work that way; in fact, they often don't consciously try to memorize lines at all. And they seldom consider memorization as defining what they do.
Study implicates defective synapse generator in onset of alzheimer's
A new UCLA/Veterans Affairs study implicates defects in the machinery that creates connections between brain cells as responsible for the onset of Alzheimer disease.
Contagious obesity?
Human adenoviruses may cause human obesity, but more research is needed before a screening test and vaccine become reality.
Giving déjà vu a second look
Many of us have experienced déjà vu - the unsettling sensation of knowing that a situation could not have been experienced, combined with the feeling that it has. It is usually so fleeting that psychologists have until recently thought it impossible to study.
Brain MRI stands up to polygraph test
Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology. Researchers from Temple University Hospital in Philadelphia used fMRI to show how specific areas of the brain light up when a person tells a lie.
Words help determine what we see
The language we speak affects half of what we see, according to researchers at the University of California, Berkeley, and the University of Chicago.
All placebos not created alike
The debate about the existence of a placebo effect has heated up over the past year as more and more lab experiments are detecting immediate physiological responses to placebos. A new study takes placebo investigations out of the lab and into a clinical trial, showing a discernible placebo effect over time, according to an article in the Feb. 1 British Medical Journal.
Researchers find that sense of smell is dependent on body position
Researchers at MIT have found a new way of looking beneath the ocean surface that could help definitively determine whether fish populations are shrinking.
Researchers prove a single memory is procesed in three separate parts of the brain
UCI researchers have found that a single brief memory is actually processed differently in separate areas of the brain - an idea that until now scientists have only suspected to be true. The finding will influence how researchers examine the brain and could have implications for the treatment of memory disorders caused by disease or injury.
