Brain Scans Show Abnormalities In Psychopaths

A USC professor used MRI brain scans, a battery of cognitive function tests, and criminal histories to compare normal people with psychopaths and also to compare psychopaths who manage to avoid getting caught with psychopaths who get arrested for committing crimes.


Outbreak of lethal bird flu confirmed in Britain

Veterinary authorities confirmed an outbreak of the potentially lethal Asian strain of bird flu in eastern England on Tuesday, in a new blow to the British farming industry.

More than 6,000 poultry were ordered to be slaughtered at the site in Suffolk, where an exclusion zone was imposed on Monday after a suspected outbreak was found.

"I can now confirm that the strain of avian influenza found in the infected premises is the highly pathogenic avian influenza H5N1 strain," said deputy chief veterinary officer Fred Landeg.


U.S. sets record in sexual disease cases

More than 1 million cases of chlamydia were reported in the United States last year - the most ever reported for a sexually transmitted disease, federal health officials said Tuesday.

Officials at the Centers for Disease Control and Prevention said they think better and more intensive screening accounts for much of the increase, but added that chlamydia was not the only sexually transmitted disease on the rise.

Gonorrhea rates are jumping again after hitting a record low, and an increasing number of cases are caused by a "superbug" version resistant to common antibiotics.


Food industry defends carbon monoxide use in meat

Two of the biggest U.S. meat processors on Tuesday defended a packaging technique designed to keep meat looking fresh at grocery stores even as U.S. lawmakers criticized it as unsafe and misleading.

Packers use carbon monoxide to stabilize the color of meat, but some Democrats said the process misleads consumers by making the products look safer than they really are, and puts the public at risk of eating spoiled meat.


Mouse Studies Confirm the Key to Longevity

Mice lacking the insulin receptor substrate are more resistant to aging than normal mice, according to University College London researchers.


The finding further confirms the link between insulin signaling pathways and aging, and may have implications on aging in humans.

In the study, mice were engineered to lack either insulin receptor substrate IRS-1 or IRS-2, both proteins that are activated by the hormone insulin, which regulates glucose and fat metabolism. Compared with normal mice, the mice lacking IRS-1 had:

* A 20 percent increase in their average lifespan (30 percent for female mice)

* Better health as they aged

In contrast, mice lacking IRS-2 had shorter lives than normal mice, and developed signs of obesity and type 2 diabetes.

Lyme disease IS all in your head

The symptoms of Lyme disease are not easy to classify. Trying to find a doctor who believes your symptoms are not psychological can be frustrating.

Bull's-eye circular skin rash (erythema migrans) appears at the bite site after three days to a month. As the patch expands, the center of the rash may clear, resulting in a bull's-eye appearance. Although the majority of people with Lyme disease dovelop the rash, 20 to 40 percent do not. (CDC)

NASA technology helps predict and prevent future pandemic outbreaks

Research presented at the American Society of Tropical Medicine and Hygiene Meeting in Philadelphia

With the help of 14 satellites currently in orbit and the National Aeronautics and Space Administration's (NASA) Applied Sciences Program, scientists have been able to observe the Earth's environment to help predict and prevent infectious disease outbreaks around the world.

The use of remote sensing technology aids specialists in predicting the outbreak of some of the most common and deadly infectious diseases today such as Ebola, West Nile virus and Rift Valley Fever. The ability of infectious diseases to thrive depends on changes in the Earth's environment such as the climate, precipitation and vegetation of an area.


Eating fish, omega-3 oils, fruits and veggies lowers risk of memory problems

A diet rich in fish, omega-3 oils, fruits and vegetables may lower your risk of dementia and Alzheimer's disease, whereas consuming omega-6 rich oils could increase chances of developing memory problems, according to a study published in the November 13, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology.

Brain matures a few years late in ADHD, but follows normal pattern

In youth with attention deficit hyperactivity disorder (ADHD), the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, an imaging study by researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has revealed. The delay in ADHD was most prominent in regions at the front of the brain's outer mantle (cortex), important for the ability to control thinking, attention and planning. Otherwise, both groups showed a similar back-to-front wave of brain maturation with different areas peaking in thickness at different times.


Connection between startled response and schizophrenia

Schizophrenia is a debilitating psychiatric illness. Its cause is currently poorly understood, and there is no known cure. In a new study published online this week in the open-access journal PLoS Biology, Akiko Watanabe and colleagues report the identification of a gene linked to the condition.

Of particular interest to the study of schizophrenia is the so-called "gating" mechanism in the brain. This mechanism organizes information that comes from the sense organs, and when it malfunctions, it is believed to be responsible for the characteristic symptoms of schizophrenia: delusions, hallucinations, and social withdrawal.
