Researchershave used neuroimaging to study the existence of ESP. The scientists used brain scanning techniques to determine if the individuals have knowledge that cannot be explained through normal perceptual processing. The results appear to disprove the existence of ESP.

  Researchers have examined whether fetal exposure to gestational obesity leads to a self-reinforcing viscous cycle of excessive weight gain and body fat which passes from mother to child. The results of a new study suggest they do.

  When a celebrity suffers a fatal sports-related head injury, it hits the national news; when the average person does, it may hit the local newspaper. Both hit home and are equally devastating and often preventable tragedies.

  Gassiness: It's embarrassing, bothersome and -- yes, smelly. Sometimes, changing diet can clear the air. Temporarily avoiding certain foods can help identify causes of gassiness. Dairy products, some vegetables, too much fruit sugar and carbonated beverages can sometimes cause the problem.

  LSU and Ohio State University will be battling for the BCS National College Football Championship in the Superdome, but if the game was held in the Louisiana wetlands instead, the entire field would disappear before halftime.

  Forgiveness may be good for your health, according to the Mayo Clinic. Holding a grudge appears to affect the cardiovascular and nervous systems. In one study, people who focused on a personal grudge had elevated blood pressure and heart rates, as well as increased muscle tension and feelings of being less in control. When asked to imagine forgiving the person who had hurt them, the participants said they felt more positive and relaxed and thus, the changes dissipated. Other studies have shown that forgiveness has positive effects on psychological health, too.

  There is new hope for patients with chronic wounds: medical scientists have been granted approval to produce artificial skin from patients'own cells. It sounds like something from a science fiction novel: Pluck a few of someone's hairs, and four to six weeks later they have grown into a piece of skin.

  Scientists have uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings. What's more, this mechanism could represent an "epigenetic"pathway -- a route that bypasses an organism's normal DNA genetic program -- for so-called Lamarckian evolution, enabling an organism to pass on to its offspring characteristics acquired during its lifetime to improve their chances for survival.

  The scary reality is that cancer cells are our own cells gone awry. Our immune system therefore doesn't always see cancer as a horrific invader. The tumor is smart, one researcher says, changing just enough to stay out of the line of fire.

  What's the key to looking and feeling better and enhancing your health? Exercise. Moderately strenuous exercise, about 30 minutes a day, can lead to enormous benefits in terms of your mood, health, weight and the ability to live an independent and fulfilling life. The exercise doesn't need to be athletic or difficult. Studies have shown that simply walking at a brisk pace for 30 minutes or more on most days can lead to significant health improvements. Add simple strengthening exercises two or three times a week and the benefits are even greater.

  A survey of advanced social organization in insects calls into question the standard explanation for eusociality Biologist Edward O. Wilson argues that natural selection acting on emergent traits of nascent colonies, rather than on individual organisms, best explains the evolution of eusociality in insects and possibly other species.

  It's hard to stay on the wagon when you're depressed, according to a new study of problem drinkers. Researchers documented the quitting success of 462 people who tried to simultaneously give up alcohol and cigarettes.

  Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. Now paleontologists, using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals.

  A new study offers reassuring evidence that people with acid reflux symptoms do not have an increased risk of death, finding no difference in survival rates between sufferers and nonsufferers.
