Researchers have achieved a new breakthrough in exploiting electromagnetic waves and will prove useful in further research for more advanced medical diagnosis.

The new research will allow researchers to build smaller more portable, easier to operate as well as cheaper terahertz waves (T-rays) systems for medical diagnostics. T-rays are used in airports scanners, medical scanning devices as well as in spectroscopy systems for materials analysis.

The rays will be able to sense molecules as every molecule has its unique signature in the THz range, according to a report in the journal Nature Photonics.

Two almost identical probes are set to orbit the moon in order to measure the uneven gravity field and the composition of the natural satellite down to its core.

The Grail spacecrafts were launched from Florida coast in September and are set to reach their destination. The two spacecrafts will arrive 24 hours apart and they are found to be on their tracks.

A team of scientists from the Harvard University have developed a new flexible robot that is capable of squeeze under obstacles and reach tight places.

The new robot has several advantages over earlier robots that are more rigid with wheels and are difficult to navigate in difficult terrain. The robot, which is inspired by squid and starfish, was manufactured with soft materials and is driven by compressed air.

American space agency, NASA is planning to launch its most powerful and advanced robotic rover designed to explore Mars and look for signals of life on the red planet.

The Mars Science Laboratory is a six wheel vehicle that is powered by nuclear fuel. NASA is set to launch the robotic rover at 10:02 am from Cape Canaveral Air Force Station in Florida on an Atlas V rocket.

An American scientists working in Antarctica, who was apparently stranded for about two months following a suspected stroke, has been airlifted from the South Pole to Christchurch, New Zealand and is now undergoing treatment.

Renee-Nicole Douceur is suspected to have suffered a stroke in August. She was working at the Amundsen-Scott South Pole research station. Raytheon Polar Services, the employer of the scientist, has not commented on the nature of her illness.

A team of scientists have found a particle that travels at a speed great that that of light, raising fundamental questions on the principles of modern physics.

Albert Einstein's special theory of relativity has stated that there is not particle that travels faster than the speed of light. However, neutrinos haven been recorded traveling at a comparatively faster rate.

Retailer, Morrisons is facing criticism after it was discovered that it is offering apples imported from China in a outlet which is situated under a mile from the lush Kent orchards that produces English varieties of Apples.

The company's Herne Bay store is selling Fuji apples from China, instead of those from local apple suppliers in the area, commonly referred to as the garden of England. The retailer's decision to stock Chinese grown apples in apple season in Britain angered local buyers as well as apple growers.

Online gamers have achieved a new feat by deciphering the structure of an enzyme of an AIDS-like virus, which has been troubling scientists since years.

The target was a monomeric protease enzyme, a complex molecular tailoring of retroviruses, a family that includes HIV. It is important to figure out the structure of proteins to investigate many diseases and developing drugs against them.

According to anew research, much of the gold on Earth came to the planet from out space after a big explosion of meteorites around 4.3billion years ago.

Scientists say that they have evidence t prove that Earth's reserves of precious metals including gold and platinum landed on earth as a result of meteorite strikes. Researchers from the University of Bristol studied four-billion- year-old rocks from Greenland and found evidence of huge meteorite bombardments that created deposits.

American space agency has released a set of impressive new photos of the Apollo landing sites on the Moon.

The images taken by the robotic Lunar Reconnaissance Orbiter (LRO), clearly shows hardware parts left over by the astronauts in the 1960s and 70s. Several probes have send pictures before but these are the best yet.

A team of scientists have created 3D models of two 305-million-year-old fossil harvestmen or Opiliones in scientific language, which were the first land-based animals to evolve modern bodies.

According to the report in the online journal Nature Communications, the 3D models were created with the help of a CT scanner at the London's Natural History Museum. The team of scientists from different countries, led by scientists at Imperial College London took more than 3000 X-rays of the harvestmen fossils from France.

The American space agency, NASA has estimated that it requires more funding for developing the James Webb Space Telescope in time for its launch, which is scheduled for 2018.

NASA estimate shows that it will cost around $8.7 billion to finish the telescope, which is slated to operate at the Earth-Sun L2 Lagrange point for about five years. The agency says that it would've already spent $3.5 billion on the telescope in this financial year. It requires more funding for development and launch operations as well as science costs.

Paris, Aug 20 : Marine scientists would soon meet at the Paris-based Unesco to discuss measuring the impact of noise on marine life, the UN agency said.

The main agenda of the meeting - to be held Aug 30-Sep 1 - would be to discuss the programme of the International Quiet Ocean Experiment, Xinhua reported.

"This decade-long project aims to fill the considerable knowledge gaps in this area, so that management of ocean noise can be more informed and effective," Unesco said in a statement.

Scientists have offered two different explanations associated to the decline in the growth of methane in the atmosphere in the last decade of the 20th century, before it rose again.

Two papers that are published in today's issue of the journal Nature, present two very different theories related to the possible cause of the decline in Methane, but both the researches agree that human activities are the key element.

The first theory suggests that the decline was caused by greater commercial use of natural gas. The study was led by Dr Murat Aydin from the University of California, Irvine.

One of the five General Purpose Computers that run the shuttle awakened the Atlantis malfunctioned today, triggering an alarm that woke up the crew members about an hour and half after they went to sleep.

The crew members are not in any danger. The space agency said the crew performed a standard 30-minute malfunction procedure to transition systems management from GPC-4 to GPC-2. The GPC-4 malfunction caused the system to go off the shuttle’s network.

The Russian Space Agency is scheduled to launch a space telescope, which was planned during the cold war era, on Monday when the telescope is expected to be raised to the almost halfway to the moon.

The scientists tool more than 30 years to develop RadioAstron, which has a 10-meter antenna. This may see small but when RadioAstron’s signals are combined with that of earthbound telescopes, the process creates images as sharp as those produced by a single satellite whose dish was as wide as the distance between the space telescope and Earth.

Conservationist groups are campaigning against an appeal from Japan to resume small-scale commercial whaling near its coasts and are urging all countries to oppose the move.

According to a new study, cities and urban centers can be of great help in soaking up carbon dioxide (CO2), which is the main greenhouse gas resulting in global warming.

The study says that even as the urban centers, which account for about four percent of the world's land surface and is rising due to increasing population of the world, are believed to lack "sinks" where vegetation soaks up CO2 naturally, they can make a significant contribution.

The Indian Space Research Organization, falling short of transponders, was planning to take transponders on rent from other countries. The ISRO department required 200 transponders and the association will acquire them on rent till the time their new satellite is developed and ready to take up the operations.

During the year 2007, ISRO had 211 transponders; their targets were to launch 500 transponders in the satellite by March 2012, but due to defect in the transponders and premature terminations of transponders, the target became unable to be achieved.

GSAT-12, a 1,410kg India’s communications satellite will be launched on July 12. The Indian Space Research Organization’s (ISRO) engineers are preparing the Polar Satellite Launch Vehicle (PSLV-C17) at Sriharikota Space Centre so that it can carry GSAT-12. Finally, the long wait of 9 years is about to be over for the researchers.
