Transgenic Animals

Dec 13, 2010
There is so many definition about transgenic animals but the most accepted is the one given by the Federation of European Laboratory Animal Association according to which it is an animal in which there has been deliberate modification of its genome.

Tiny Circuit Boards

Dec 13, 2010
Scientists at the California Institute of Technology and IBM have developed a new technique to orient and position selfassembled DNA shapes and patterns on surfaces that are compatible with today’s semiconductor manufacturing equipment.

Tiny Chance of Planet Collision

Dec 13, 2010
Astronomers calculate there is tiny chance that Mars or Venus could collide with Earth though it would not happen for at least a billion years. The finding comes from simulations to show how orbits of planets might evolve billions of years into the future.

Swine flu strikes India

Dec 13, 2010
At last swine flu also struck India. Initially the cases of infection were largely imported from North America. But eventually the transmission of the virus was taking place even among those who were never in direct contact with people returning from abroad.

Secrets of dark energy to be unveiled

Dec 13, 2010
Way back in 1920s, the American astronomer Edwin Hubble discovered that the universe is expanding, with galaxies moving away from each other at velocities proportional to their mutual distances. At that time astronomers also believed that the rate of expansion will slow down in future.

Oxygen produced from Moon rock

Dec 13, 2010
Moon is devoid of oxygen. Any astronaut who has to travel to moon would have to carry a lot of oxygen and this a very costly affair. Perhaps costing as much as US$100 million per tonne according to some estimates. Now, scientists are examining potentially cheaper ways to produce oxygen on the Moon itself.

New way to recycle carbon

According to US scientists burying huge amounts of crop residue in the bottom of deep oceans is a good way to ensure that carbon stays captured.

Nano Technology

Dec 11, 2010
Imagine a world in which cars can be assembled molecule by molecule, garbage can be disassembled and turned into beef steaks and people can be operated on and healed by cell-sized robots. It may sound hilarious and straight from the science fiction.

Nano Robots

Dec 11, 2010
Tiny robots small enough to enter the human body are being developed by researchers for a variety of purposes including treating cancer, drug delivery and even the growth of new cells and tissues.

Microbes can clean wastewater

Dec 11, 2010
It is very costly to purify and desalinate dirty water. Two methods are traditionally used to desalinate water. One process is called reverse osmosis and another process is called electrodialysis which uses electricity to draw salt ions out of water through a membrane.

Methane on Mars

Dec 11, 2010
A recent finding has raised interesting possibilities about the presence of life on Mars. The US space agency NASA has reported the discovery of huge release of methane gas into red planet’s atmosphere.

Lunar eclipse may provide clue to the presence of life

Dec 11, 2010
Now astrobiologists are excited about the lunar eclipse. It is because the light that is reflected back from the moon during the eclipse carries clues indicating the presence of light on a planet. This was revealed during a lunar eclipse on August 16, 2008.

Liquid water found on Mars

Dec 11, 2010
NASA’s Phoenix Mars Lander landed on the red planet in May, 2008. Now, NASA claims that the Phoenix may have found liquid water also.

Life probably originated from comet dust

Dec 11, 2010
Scientists have to solve the mystery of origin of life on Earth, though many hypothesis have been put forward by the scientists time to time.

Kepler makes discovery of atmosphere in exoplanet

Dec 11, 2010
The NASA spacecraft Kepler has detected atmosphere around a known giant gas planet. The spacecraft was launched in March 2009. This discovery was made after analysis of just the first 10 days data.
