Fighting obesity by electricity

The majority of mankind is now concerned over the increasing trend of obesity not only to the children but also to the adult.
Medical professionals are trying many ways to curb the disease. Many are successful and many are not.Now doctors at Mayo clinic are working with a company called ENTEROMEDICS on the VBLOC{Vagal blocking for obesity control}. VBLOC is insertwd laproscopically and uses electricity to use the vagus nerve,which connects the brain and the stomach. It prevents the stomach from increasing the size when someone eats. It satisfy the human with less food. The device turns on and off during the day,and shuts off for a period at night. An international study of 30 people has shown promising results and a larger final-phase trial is planned. It is uncler how much one will loose fat using this device!! But the researchers predict a 15 to 20 percent

Moon of earth is a rare cosmic phenomena


According to scientists the moon was created when an object as big as the planet Mars smacked into the Earth billions of years ago. Debris were splited and started to move in orbit of earth,later they consolidated to form the moon.
The Astrophysical Journal reports that just 5-10% of planetary systems in the Universe have moons created this way. Huge dusts were created in this collision and later consolidated. But this type of collision occur rarely because huge dusts are not seen around the stars. The age of moon is calculated equal to that of our sun.

Fish inside water is not hurt by lightning

Lightening does electrocute fish if they are close enough to the strike.
However,a charge that strikes water tends to dissipate rapidly along the surface,giving natural protection to under water animals. Another reason we don't see waves of dead fish after an electrical storm is that lightning rarely hits bodies of water.

Fish have an involuntary muscular reaction to a mild stream of electricity. Those orient themselves towards the positive side of the field,though some start swimming the opposite way. They are also less conductive than human or water,if the water is salty or muddy.

But it is dangerous for human in water when there is an electrical storm.
