Electronic Implant Controls Appetite and Weight Gain
A team of British researchers will soon begin testing an electrical device which, by attaching to a nerve that controls the body's appetite for food, could provide an alternative to weight-loss surgery.
What's the Latest Development?
A team of British researchers will soon begin testing an electrical device which, by attaching to a nerve that controls the body's appetite for food, could provide an alternative to weight-loss surgery. "It involves an 'intelligent implantable modulator', just a few millimetres across, which is attached using cuff electrodes to the vagus nerve within the peritoneal cavity found in the abdomen. The chip and cuffs are designed to read and process electrical and chemical signatures of appetite within the nerve. The chip can then act upon these readings and send electrical signals to the brain reducing or stopping the urge to eat."
What's the Big Idea?
Using electrical impulses to regulate how the vagus nerve functions might have applications beyond weight loss, say biologists. Besides controlling appetite, the nerve controls the way we breathe, our heart rate, the secretion of acids in the digestive system and the contraction of the gut. "It also feeds back information to the brain on how various body systems are operating." Dr Tony Goldstone, an expert on obesity at the MRC Clinical Sciences Centre said: "We need simpler cheaper more regularly available procedures, and unlike gastric bypass and some other operations for obesity, it is reversible—that is another advantage."

Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
Nazi supporters held huge rallies and summer camps for kids throughout the United States in the 1930s.
- During the 1930s, thousands of Americans sympathized with the Nazis, holding huge rallies.
- The rallies were organized by the American German Bund, which wanted to spread Nazi ideology.
- Nazi supporters also organized summer camps for kids to teach them their values.

- A new study finds drinking large amounts of coffee and tea lowers the risk of death in some adults by nearly two thirds.
- This is the first study to suggest the known benefits of these drinks are additive.
- The findings are great, but only directly apply to certain people.
