It sounds different because it is different. "When you speak, the vocal folds in your throat vibrate, which causes your skin, skull and oral cavities to also vibrate, and we perceive this as sound," explains Ben Hornsby, a professor of audiology at Vanderbilt University. The vibrations mix with the sound waves traveling from your mouth to your eardrum, giving your voice a quality — generally a deeper, more dignified sound — that no one else hears.

Through a loudspeaker or recording device, you pick up sound only through air conduction. "The sound we're used to hearing has a lower frequency from the bone vibrations," Hornsby says. "We like that because it sounds rich and full." Many people cringe at the playback sound because our brain struggles to accept that this foreign voice is our own !!!

A team in the southwest German city of Darmstadt first produced 112 in 1996 by firing charged zinc atoms through a 120-meter-long particle accelerator to hit a lead target.

"The new element is approximately 277 times heavier than hydrogen, making it the tabel heaviest element in the periodic table," the scientists at the GSI Helmholtz Center for Heavy Ion Research said in a statement late on Wednesday.

The zinc and lead nuclei were fused to form the nucleus of the new element, also known as Ununbium, Latin for 112.

The International Union of Pure and Applied Chemistry (IUPAC), confirmed the discovery of 112 by the team led by Sigurd Hofmann at the Helmholtz Center. IUPAC has asked for an official name for the element to be submitted.

John Jost, executive director of IUPAC in North Carolina, told Reuters that creating new elements helped researchers to understand how nuclear power plants and atomic bombs function.

The atomic number 112 refers to the sum of the atomic numbers of zinc, which has 30, and lead, which has 82. Atomic numbers denote how many protons are found in the atom's nucleus.

Scientists at the Helmholtz Center have discovered six chemical elements, numbered 107-112, since 1981. The remaining five elements have already been recognized and named.

In 1925, scientists discovered the last naturally occurring element on the periodic table. Since then researchers have sought to create new, heavier elements.

Proving the existence of atoms with such a high mass, the so-called superheavy elements, is a complex procedure because they exist for only tiny fractions of a second and then decay radioactively into other elements.

The map is the culmination of an assessment carried out by the US Geological Survey (USGS). An estimated 30% of the world's undiscovered gas and 13% of its undiscovered oil may be in the Arctic, according to a map published on Friday.

Writing in the journal Science, its authors say the findings are "important to the interests of Arctic countries".

But, they add, they are unlikely to substantially shift the geographic pattern of world oil production.

According to the new map, the majority of oil is likely to be found underwater, on continental shelves.

Surrounding nations, including Russia, United States, Canada, Denmark and Norway, have all already sought to assert their jurisdiction over parts of the Arctic.

In 2007, two Russian civilian mini-submarines descended to the seabed to collect geological and water samples and to drop a titanium canister containing the Russian flag.

And do i still need to write that , due to this finding … there might be ( for which we are sure ) “conflicts of interests” in surrounding countries … lets hope that it don’t start any active war !!!
