Virotherapy to treat cancer

Dec 13, 2010
Virotherapy is a cancer treatment method in which viruses are reprogrammed to attack cancer cells in the body.

Video advertisement in magazine

Dec 13, 2010
Very soon, US readers are going to get what they have never thought even in their wildest of dreams-video advertisement in a magazine.

Unique Case of Liver Swapping

Dec 13, 2010
Eighteen year old DK from Nigeria and 44 year old Priya Ahuja from Mumbai were suffering from same kind of problem. Both had liver problem and they were in dire need of liver transplantation.

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

Dec 11, 2010
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.

ISRO discovers bacteria in the stratosphere

Dec 11, 2010
Recently, Indian Space Research Organisation (ISRO) conducted a balloon experiment in stratosphere in which three species of bacteria unknown on Earth have been found. All three species are highly resistant to ultraviolet radiation.

Heart muscles regenerate

Dec 11, 2010
It is a common belief that heart muscles never regenerate and precisely because of this people are not only scared about heart attacks but also the attendant damage to the heart muscles. It has long been believed that cell division in the heart stops after birth.

Green Revolution in Biotech

Dec 11, 2010
The 20th century was specially revolutionary in the field of science. During this century the foundations of biochemistry were firmly laid. Biochemistry basically dealt with the basic principles of metabolic processes inside living cells.

Geomagnetic eyes in birds

Dec 11, 2010
Superoxide is a toxic free radical which help birds see the earth’s magnetic field with the help of which birds migrate from one place to another. Birds eyes have a photoreceptor called cryptochrome that acts as a biochemical compass.

Genome of Neanderthal unravelled

Dec 11, 2010
Genome of Neanderthal unravelled

Gene therapy cures child blindness

Dec 11, 2010
The US researchers have been able to reverse the damaging effects of a rare inherited and progressive eye disease called Leber’s congenital amaurosis by using gene therapy. This genetic disease appears at birth, or in the first months of birth and affects around 1 in 80,000 of the population.

Fermionic Condensates

Dec 11, 2010
Researchers have discovered a weird new phase of matter called fermionic condensates. We always learnt in school there are three forms of matter: solids, liquids and gases. But that is not even half truth.

Extra-Solar carbon dioxide found

Dec 11, 2010
For the first time carbon dioxide has been detected on a planet outside our solar system.

Data transmission may be made more energy efficient

Dec 11, 2010
Sending information through WiFi and the cellular networks always means losing energy for every bit of information that is transmitted.

Chemical robots for medicine

Dec 11, 2010
In a pair of small laboratories in Prague, a swarm of tens of millions of robots is being prepared to be set loose en masse. But these won’t be typical robots with gears and motors.

Charge Mobile Without Charger

Dec 11, 2010
Now you need not to worry about your mobile being discharged right in the middle when you needed an urgent phone call. Now rejuvenate your battery simply by pressing the mobile keypad or dialling the number.

Bacterial Circuits

Dec 11, 2010
By interfacing bacteria to silicon chips, researchers have created a device that can sense almost anything. This particular quality of bacteria can be seen in canary in a mine which is a microbe which can often sense environmental dangers before a human can.
