Despite their huge popularity among young and adult players, video games continue to remain a controversial aspect in people's lives. One element researchers are most interested in when it comes to video games is the impact they have on children, namely how increasingly aggressive they become as they experience violent content.
A recent study by Iowa State University Researchers revealed that violent video games affect children no matter the culture. In order to prove that, they conducted a study on the effects of violent video games on the level of aggression in children from the United States and Japan over a 3 to 6 month period. The results have been published in detail in the November issue of Pediatrics.
Omega-3 fatty acids from fish oil may help maintain the body's healthy response to inflammation, preventing the immune response from getting out of hand and leading to cardiovascular disease, according to a study conducted by researchers from Baylor College of Medicine and Harvard Medical School, and published in the Journal of the Federation of American Societies for Experimental Biology.
Both first- and second-generation immigrants to the United Kingdom appear to have a higher risk of psychoses than white British individuals, according to a new report.
An elevated risk for psychoses - psychiatric disorders such as schizophrenia that are characterized by a disconnect from reality - have been observed among migrant groups since 1932, when Norwegians moving to the United States displayed higher rates, according to background information in the article. "Immigration is an important life event and difficulties in assimilation may remain chronic as conceptualized within the stress-vulnerability model of risk for psychosis, although individual risk is still considered to be mediated through genetic susceptibility," the authors write.
A discovery from the Oklahoma Medical Research Foundation has put scientists are one step closer to finding a defense against dangerous antibiotic-resistant bacteria, sometimes called "superbugs."
In a study that will be published in the Nov. 11 edition of the Proceedings of the National Academy of Sciences, OMRF researchers Philip Silverman, Ph.D., and Margaret Clarke, Ph.D., have obtained the first visual evidence of a key piece in the puzzle of how deadly superbugs spread antibiotic resistance in hospitals and throughout the general population.
"These 'superbugs' have become increasingly common since the widespread use of antibiotics began and they are now a serious public health menace," said Silverman, who holds the Marjorie Nichlos Chair in Medical Research at OMRF. "Now, for the first time, we can begin to see, literally, how they acquire and disseminate antibiotic resistance."
The drug is the chemical cousin of an extract in red wine
French scientists say they have found a drug that tricks the body into burning off fat even when on a high-fat diet.
The University of Louis Pasteur team found the drug protected mice against weight gain and insulin resistance.

The main principles governing the pharmaceutical "business with disease." It is not in the financial interests of the pharmaceutical industry to prevent common diseases - the maintenance and expansion of diseases is a precondition for the financial growth of this industry.
1. The pharmaceutical industry is an investment industry driven by the profits of its shareholders. Improving human health is not the driving force of this industry.
A new virus that causes fatal hemorrhagic fevers has been discovered in southern Africa. It killed four people in South Africa and sickened a fifth, but health authorities believe the outbreak has been contained.
The virus is a member of the arenavirus family, which also includes the causes of Lassa fever in West Africa and several South American fevers. While new viruses are often found in animals - a new blue-tongue virus was found in Swiss goats last month, for example - it is relatively rare to discover one fatal to humans, like the SARS coronavirus in 2002 or the sin nombre hantavirus in 1993.
How the first victim was infected is unknown, but arenaviruses are common in rodents; their dried urine, inhaled while sweeping, can transmit infection.

Schools are being urged to buy bigger chairs because of booming obesity rates among children.
Many young people in Britain are now too fat for classroom furniture that has remained almost unchanged since the 1960s, it is claimed.
A policy commission - led by Charles Clarke, the former Education Secretary - said growing numbers of children were also suffering from back pain due to unsuitable school chairs.
Most schools are continuing to stock cheap furniture built to 50-year-old specifications to save cash, it suggests.
Snakebites cause considerable death and injury worldwide and pose an important yet neglected threat to public health, says new research published in this week's PLoS Medicine
The study used the most comprehensive methods yet to estimate that at least 421,000 envenomings (poisonous bites) and 20,000 deaths from snakebites occur each year, especially in South and South East Asia and sub-Saharan Africa.
To estimate death and injury from snakebite, Janaka de Silva (University of Kelaniya, Sri Lanka) and colleagues conducted a systematic review of the scientific literature, reviewed county-specific mortality data from databases maintained by United Nations organizations, and identified unpublished information from Ministries of Health, National Poison Centres, and snakebite experts on snakebites in countries that do not have reliable data on snakebite incidence and mortality.
WASHINGTON - Think achy joints are the main reason we slow down as we get older? Blame the brain, too: The part in charge of motion may start a gradual downhill slide at age 40.
How fast you can throw a ball or run or swerve a steering wheel depends on how speedily brain cells fire off commands to muscles. Fast firing depends on good insulation for your brain's wiring.
