How key enzyme repairs sun-damaged DNA
Researchers have long known that humans lack a key enzyme that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. In the early online edition of the journal Nature, Ohio State University physicist and chemist Dongping Zhong and his colleagues describe [...]
India’s PSLV- C15 successfully launches CARTOSAT – 2B Satellite
Today (on July 12, 2010) India’s Polar Satellite Launch Vehicle (PSLV-C15) successfully launched CARTOSAT – 2B from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch of PSLV – C15 was the sixteenth consecutive successful flight of PSLV. PSLV is the first operational launch vehicle of Indian Space Research Organisation (ISRO). PSLV is capable of [...]
ESA probe takes detailed pictures of Asteroid Lutetia
European Space Agency (ESA)’s Rosetta mission has sent back the first close-up images of an asteroid that scientists hope will help in understanding the birth and evolution of the Solar System. The images of asteroid Lutetia were taken during a successful flyby on Sunday. The closest approach took place at 18:10 CEST, at a distance [...]
Deep Impact Spacecraft to Make Final Flyby of Earth
On Sunday, US space agency NASA’s historic Deep Impact spacecraft will fly past Earth for the fifth and last time on its current University of Maryland-led EPOXI mission. At time of closest approach to Earth, the spacecraft will be about 30,400 kilometers (18,900 miles) above the South Atlantic. Mission navigators have tailored this trajectory to [...]
Response to Vaccines change with Gender
Biological differences between the sexes may significantly affect responses to vaccines, according to the researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers examined published data from numerous adult and child vaccine trials and found that sex is a fundamental, but often overlooked predictor of vaccine response. The findings, published in the [...]
Atlantis ready for final mission to Space Station

India’s GSLV-D3 launch fails
The launch of Geosynchronous Satellite Launch Vehicle (GSLV-D3), powered by India’s first indigenous Cryogenic Engine, failed on Thursday. The rocket took off as planned but crashed into the sea five minutes after the launch. GSLV-D3 was carrying a geo-stationary experimental satellite (GSAT-4). With this, India lost a chance to join an elite club of five [...]
Discovery of 9 new planets challenges the theory of Planet Formation
A team of astronomers have discovered 9 new planets outside our solar system! The nine planets are called "Hot Jupiters." Unlike the planets in our solar system, two of the newly discovered planets are orbiting in the opposite direction to the rotation of their host star. This, along with a recent study of other exoplanets, [...]
Discovery of World’s Deepest Undersea Volcanic Vents
A British scientific expedition has discovered the world’s deepest undersea volcanic vents, known as ‘black smokers’, 3.1 miles (5000 metres) deep in the Cayman Trough in the Caribbean. Using a deep-diving vehicle remotely controlled from the Royal Research Ship James Cook, the scientists found slender spires made of copper and iron ores on the seafloor, [...]
Image of a rare Stellar Eclipse
For the first time, a team of astronomers has imaged the eclipse of the star Epsilon Aurigae by its mysterious, less luminous companion star. Very high-resolution images, never before possible, have been published online in the journal Nature Letters. Take a look at the artist’s concept image, depicting Epsilon Aurigae (the supergiant star at right) [...]
