Contemplative brain network less complex in children

A brain network linked to introspective tasks - such as forming the self-image or understanding the motivations of others - is less intricate and well-connected in children, scientists at Washington University School of Medicine in St. Louis have learned.

Low-intensity exercise reduces fatigue symptoms by 65 percent

Sedentary people who regularly complain of fatigue can increase their energy levels by 20 percent and decrease their fatigue by 65 percent by engaging in regular, low intensity exercise, according to a new University of Georgia study.

Discovery of potential drug targets for sepsis

"We have identified a key connection of signaling pathways in the cascade of events leading to sepsis. This defines a crucial point where the immune system spirals out of control to cause severe sepsis and where there is an opportunity for therapeutic intervention," says Scripps Research Professor Wolfram Ruf, who led the research with his postdoctoral fellow Frank Niessen.

New vaccine technology decreases E. coli in beef cattle

Despite millions of dollars spent on food safety research over the last 10 years, ground beef recalls due to E. coli O157:H7 were higher in 2007 than in 2006, according to researchers from Kansas State University and West Texas A&M University. E. coli O157:H7 has been linked to foodborne illnesses in humans after consuming contaminated beef and produce.

Hormones produced by the heart eliminate pancreatic cancer in mice

Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).

You are what you eat and drink - and that is recorded in your hair

University of Utah scientists developed a new crime-fighting tool by showing that human hair reveals the general location where a person drank water, helping police track past movements of criminal suspects or unidentified murder victims.

2 oxygenation events in ancient oceans sparked spread of complex life

The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals, according to a study reported in the Proceedings of the National Academy of Sciences online Early Edition during the week of February 25 – 29.

Childhood obesity leads to higher rate of problems during surgery

Add this to the growing list of health challenges faced by obese children: A new study from the University of Michigan Health System finds that obese children are much more likely than normal-weight children to have problems with airway obstruction and other breathing-related functions during surgery.

Genetic defect causes immune deficiency and balance disorder

A genetic defect that causes a severe immune deficiency in humans may also produce balance disorders, according to a new study by researchers at the University of Iowa, The Jackson Laboratory and East Carolina University.
