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.

Earth's Inner Temperature Taken: It's Hot!

Scientists have measured the temperature of inner ward of earth using advanced instruments and new methods and they have found out that few thousands of miles below the earth the temperature reached 66000 degree Fahrenheit.

The finding is published in the Journal "science" which helps geologists understand how heat is transferred through planet's interior, which drives all the geological processes like earthquakes and volcanoes, and Earth's magnetic field.

Robert van der Hilst of MIT and his colleagues examined earthquake generated seismic waves in real time. These seismic waves are generated thousands of miles beneath the earth's surface, their speed depend on the material through which they travels and the existing temperature and pressure. Scientists have calculated the approximate temperature of mantle and core transition as 6500 degree and inner core 9000 degree almost equal to the surface temperature of sun.

The new temperature measurements will also helps geoscientists better understand the magnetic field of earth which protects us from cosmic rays and solar storms.

We know the Earth’s magnetic field is generated and maintained in the liquid outer core of the Earth where you basically have rapid flow of metallic iron,” van der Hilst said. Since iron is charged, the swirling iron mix sets up an electric field that gives rise to Earth’s magnetic field.

With advance of science and technology everybody should hope one day there will be affordable means to tap this tremendous energy for the benefit of the mankind.

New Neutron Star Found

Neutron stars are the collapsed cores of some massive stars. They pack roughly the mass of our Sun into a region the size of a city. We'll talk about neutron star evolution in a bit, but let's say you take your run of the mill mature neutron star, which has recovered from its birth trauma. What is its structure like? First, the typical mass of a neutron star is about 1.4 solar masses, and the radius is probably about 10 km.

A new neutron star was found out recently by the astronomers. It is the eighth known neutron star ever. Peculiar thing is that it is very nearer to our planet earth.The object has been nicknamed Calvera, after the villain in the 1960s western film The Magnificent Seven. Other seven stars were collectively known as magnificent seven. Neutron stars are formed due to supernova explosion. Stars exhaust the nuclear fuel.

This explosion blows off the outer layers of the star, forming a supernova remnant. The central region of the star collapses under gravity, causing protons and electrons to combine to form neutrons - hence the name "neutron star".

Details of the study, by a team of American and Canadian researchers, will appear in the Astrophysical Journal.
