Washington, Apr 13 : By conducting parallel studies in human and mouse, two groups of scientists have found that a new kind of gene, called a microRNA, is linked with progressive hearing loss.
MicroRNA is a tiny fragment of RNA that affects the production of hundreds of other molecules within sensory hair cells of the inner ear.
One team, led by researchers from the Hospital Ramon y Cajal, Madrid, Spain, followed families who showed hearing loss.
New Delhi, April 13 : China is all set to launch the second satellite, the Chinese version of Global Navigation Satellite System (GNSS), into the orbit on Wednesday.
This was announced by a spokesman of the Xichang Space Launch Center, in southwest China's Sichuan Province.
Both the rocket, a Long March-III carrier, and the satellite are in sound conditions and ready for the planned projection, according to the official.
Washington, April 13 : Researchers at the University of California-San Francisco (UCSF) have successfully used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state.
The researchers say that the reprogrammed cells have the capacity to become any cell type in the body.
Their finding suggests that it may soon be possible to replace retroviruses and even genes currently used in laboratory experiments to induce pluripotency in adult cells.
Washington, April 12 : A 1,500-year-old tomb of the Moche Indian "king of bling", found in Peru at the base of an eroded mud-brick pyramid, has yield a treasure trove of artifacts, which are shedding light on ancient times in the country.
According to a report in National Geographic News, the finds include 19 golden headdresses, various pieces of jewelry, and two funerary masks, as well as skeletons of two other men and a pregnant woman.
Moscow - Russia on Sunday re-opned its cosmonauts museum after three years of renovation and expansion work. The Moscow museum, opened on the annual Cosmonauts Day, is four times as large as the previous faciltiy.
Moscow mayor Yuri Luskhov said at the opening ceremonies that Russia now had a museum where people could grasp the "magnificence of space." There was nothing comparable to it anywhere else in the world.
Washington, April 12 : An Indian-origin researchers at the Massachusetts Institute of Technology (MIT) has come up with a new way for etching extremely narrow lines on a microchip by exposing it to certain wavelengths of light.
Research engineer Rajesh Menon and his colleagues call the new technique absorbance modulation.
The researchers say that this technique makes it possible to create lines that are only about one-tenth as wide as the wavelength of light used to create them.
