Researchers in Japan are reporting new evidence that the ordinary vinegar — a staple in oil-and-vinegar salad dressings, pickles, and other foods — may live up to its age-old reputation in folk medicine as a health promoter. They are reporting new evidence that vinegar can help prevent accumulation of body fat and weight gain.

Tomoo Kondo and colleagues note in the new study that vinegar has also been used as a folk medicine since ancient times. People have used it for a range of ills. Modern scientific research suggests that acetic acid, the main component of vinegar, may help control blood pressure, blood sugar levels, and fat accumulation.

Their new study showed that laboratory mice fed a high-fat diet and given acetic acid developed significantly less body fat (up to 10 percent less) than other mice.

Importantly, the new research adds evidence to the belief that acetic acid fights fat by turning on genes for fatty acid oxidation enzymes. The genes churn out proteins involved in breaking down fats, thus suppressing body fat accumulation in the body.

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 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.
