AWARDS
National Technology Award, 2010
A pioneer in processing rice bran oil, A.R. Sharma, who comes from dusty town of Dhuri in Sangrur district, has been honoured with the national award by the Technology Development Board of the Ministry of Science and Technology. Former President Dr A.P.J. Abdul Kalam presented the award—Rs 10 lakh and a trophy—to him.

Sharma is the chairman-cum-managing director of the A.P. Organics (P) Ltd, a part of Rs 500-crore A.P. Solvex Group of Companies. The group is the largest producer of refined rice bran oil, a health-friendly cooking oil produced from the outer brown layer of rice.

For the past over 50 years, the rice bran oil is being used as a premium cooking oil in countries like Japan, Korea, China and Thailand. In Japan, it is popularly known as “Heart Oil” because of its scientifically proven cholesterol-lowering properties.

India is the second largest producer of paddy in the world, having potential to produce over 12 lakh tonnes per annum of this healthy cooking oil. Unfortunately, it is used in India more in producing soaps and detergents than as a nutritious and healthy cooking oil.

“Our group enjoys the distinction of being pioneer in development of an eco-friendly and health-friendly cooking oil,” says Sharma, holding that the process used by the group for production of refined rice bran oil is economical and scientifically proven process. The patent for the process is registered with the Government of India in my name,” adds Sharma.

 “Lost” Booker Prize
Late author J.G. Farrell has been honoured for his novel Troubles, 40 years after it was first published, in an unusual take on Britain's most prestigious literary award, the Booker Prize.

He scooped The Lost Booker Prize, an award for books from 1970 which missed out the first time around because of a rule change in 1971. Previously the prize, which began in 1969, was retrospective, meaning the 1970 award went to novels published the previous year—but the 1971 prize went to those published in 1971.

DEFENCE
Light Combat Helicopter takes to skies
The maiden flight of the indigenously manufactured Light Combat Helicopter (LCH) on May 22, 2010, heralded India's entry into the select group of countries capable of developing their own combat helicopters.

The LCH, manufactured by the Hindustan Aeronautics Limited is a dedicated attack helicopter featuring a narrow fuselage and a tandem seating for the pilot and co-pilot. The machine is designed for low detection (reduced visual, aural, radar and infra-red signatures) and has crash-worthy landing gear for better survivability. The hinge-less rotors and the powerful Shakti engines enable the easy manoeuvring of LCH even with weapons.

The other interesting feature of the LCH is the chin-mounted canon along with the helmet mounted sighting system, which gives the pilot the capability to look and fire at targets around the aircraft. An advanced sensor suite consisting of CCD camera, forward looking infra-red imaging technology and laser range finder facilitates target acquisition in all weather conditions.

The helicopter would be fitted with a data link for network-centric operations facilitating the transfer of mission data to the other airborne platforms and ground stations operating in the network, thus facilitating the force multiplication.

With these features, the LCH is expected to play a major role in air defence against slow moving aerial targets, destruction of enemy air defence operations, escort to special heli-borne operations, support of combat search and rescue operations, anti-tank role and scout duties.

EXPEDITION
First Indian to sail solo around the world
On May 22, 2010, Commander Dilip Donde of the Indian Navy became the first Indian ever to circumnavigate the globe solo on a sail-boat when he steered into the Mumbai harbour after his arduous effort spanning a little over nine months.

Commander Dilip Donde, who started the voyage on August 19 2009 on INSV Mhadei, touched base back in India at the Sunk Rock Light House in Mumbai. His boat was ceremonially escorted by a fast attack craft of the Indian Navy, along with speedboats and two tugs operating their water cannons. Vice-President Hamid Ansari, along with Chief of Naval Staff Admiral Nirmal Kumar Verma and Donde’s family members, who were on board INS Delhi, anchored at the finish line, witnessed the historic moment and gave him a rousing reception.

The 56-foot-long Mhadei, with 23-tonne displacement, is the first fibreglass yacht constructed entirely in India and boasts of state-of-the-art navigation and communication equipment. The 276-day voyage was part of the Navy's daunting Sagar Parikrama project, which aims to revive the old tradition of sea faring.

The 42-year-old officer covered 21,600 nautical miles sailing in the seas to achieve the milestone. He sailed through the Pacific Ocean, the Atlantic Ocean and the Arabian Sea. He also sailed along the Equator. He made only four halts during the voyage, at Fremantle-Australia, Christchurch-New Zealand, Port Stanley-Falkland Islands and Cape Town-South Africa. Donde had trained for the expedition with legendary Sir Robin Knox-Johnston, the first man to sail solo and non-stop round the world in 1968-69.

The world record for the fastest solo circumnavigation was set in January 2008 by Frenchman Francis Joyon, at 67 days, 13 hours, 34 minutes and 6 seconds.

PERSONS
Kapadia, Justice Sarosh Homi
He has been appointed as the 38th Chief Justice of India. Hailing from a poor family, Justice Kapadia replaced Justice Balakrishnan.

Born on September 29, 1947, he is the first CJI born in post independence era. An erudite man with a keen interest in Economics, Public Finance, Theoretical Physics and Hindu and Buddhist philosophies, he would remain at the helm of the judiciary till September 29, 2012.  He started his career as a class IV employee and possesses integrity as “the only asset”.

Justice Kapadia was part of the Constitution bench that in January 2007 declared that laws placed under the protective umbrella of the Ninth Schedule of the Constitution were open to judicial review.

RESEARCH
First life-form made by man
Scientists have created the world’s first synthetic life form in a landmark experiment that paves the way for designer organisms that are built rather than evolved.

The controversial feat, which has occupied 20 scientists for more than 10 years at an estimated cost of $40 million, was described by one researcher as “a defining moment in biology”.

Craig Venter, the pioneering US geneticist behind the experiment, described the converted cell as “the first self-replicating species we’ve had on the planet whose parent is a computer.” He said the achievement heralds the dawn of a new era in which new life is made to benefit humanity, starting with bacteria that churn out bio-fuels, soak up carbon dioxide from the atmosphere and even manufacture vaccines.

The new organism is based on an existing bacterium that causes mastitis in goats, but at its core is an entirely synthetic genome that was constructed from chemicals in the laboratory. The single-celled organism has four “watermarks” written into its DNA to identify it as synthetic and help trace its descendants back to their creator, should they go astray.

The team now plans to use the synthetic organism to work out the minimum number of genes needed for life to exist. From this, new micro-organisms could be made by bolting on additional genes to produce useful chemicals, break down pollutants, or produce proteins for use in vaccines.

Most scientists agree Venter has achieved a technical feat in synthesizing the largest piece of DNA so far—a million units in length—and in making it accurate enough to substitute for the cell’s own DNA.

The US President Barack Obama has asked the White House bio-ethics commission to complete a study of the issues raised by synthetic biology within six months and report back to him on its findings. He said the new development raised “genuine concerns,” though he did not specify them further.

Indian discovers new, more environmental friendly technique to extract rare earth minerals
Fears that China may end up ruling a green world have been partly rested by a technological breakthrough by an NRI scientist in the field of rare earth metals—key components of technologies that are set to shape our future.

Bhagalpur-born Animesh Jha, a material sciences professor at Leeds University and an alumnus of Roorkee University and Indian Institute of Science, Bangalore, has isolated significant quantities of rare earth metals while refining low-grade titanium dioxide—a common mineral.

In the process, he may have soothed the jangly nerves of governments and manufacturers of leading-edge technologies around the world—in a state of uncertainty after China, which produces 95 per cent of the world’s rare earth declared in 2009 that it was sharply reducing its exports of the metals.
Rare earths—versatile metals that are really not so rare—have come to dominate growing areas of people’s day-to-day lives around the world. From laptop hard disks, iPod headphones and mobile phone speakers to aerospace, defence, medicine, laser, super-conductivity and atomic energy, rare earth metals sparkle with endless promise.

Accelerated global attempts to forge a green future too are tied to supplies of rare earth metals—they make the strongest magnets on the planet, which are then used in motors that drive wind turbines as well as hybrid cars.

There are only 17 rare earth metals, and it is China where they are mostly found.

It’s not as if there are no substantial rare earth deposits elsewhere around the world: far from it. But existing US mines shut down in the mid-1980s, unable to compete with cheap Chinese exports, with the supply chain eventually moving to China. And opening new mines is a long and cumbersome process.

There are also massive environmental concerns over the way these metals have been extracted (by acid leaching) in many of the mines. Inner Mongolia, home to 75 per cent of China’s reserves, is said to resemble a desolate moonscape.

This is where Jha’s breakthrough becomes important: not only is it a potential alternative to Chinese supplies, but by removing the need to scar the earth for high grade titanium dioxide, it also offers a clean solution that chimes in with attempts to combat climate change.

Working with half a million pounds in the laboratories of the Institute for Materials Research in Leeds, Jha and his small team of researchers found that they could extract rare earth metals at the very start of the titanium dioxide refining process.

Leeds University says the new process could “eventually shift the balance of power in global supply, breaking China’s near monopoly.”

If Jha succeeds in scaling up his process, it could become a small but important step toward creating a sustainable world.

SPACE RESEARCH
Space shuttle Atlantis lands for final time
On May 26, 2010, Atlantis and its six-man crew landed at Florida’s Kennedy Space Center marking the end of Atlantis’ 25 years of service. Only two shuttle missions remain, by NASA’s two other spaceships.

The space agency would like Atlantis to return to the International Space Station in June 2011. But that’s not in the cards unless the White House grants a reprieve.

The space station construction mission boosted Atlantis’ mileage to just over 193 million km, accumulated over 32 flights. The shuttle and its astronauts left the outpost bigger and more powerful, adding a new compartment and fresh batteries.

MISCELLANEOUS
BRO turns 50
Exactly 50 years ago, on May 5, 1960, with war clouds gathering on the Sino-Indian border, Jawaharlal Nehru created the Border Roads Organisation (BRO), an inter-ministerial task force that has become an Indian exemplar of grit and fortitude. Thanks to over 48,000 kilometres of BRO roads, soldiers now drive to far-flung border pickets that earlier involved days of marching.

Since the time the BRO’s first chief, the dashing Major General Kartar Nath Dubey, pushed through the first roads to Tawang and Chushul in the early 1960s, the BRO has become a reassuring presence on India’s borders. Every spring, it cuts through walls of snow in high-altitude passes to clear 95 roads, like the Srinagar-Kargil highway. The BRO is over-seeing the 8.8-km long Rohtang tunnel, which will allow traffic to Lahaul-Spiti to flow around the year. It has constructed 19 border airfields and 400 major bridges. It is currently working on 699 roads, having a total length of 28,000 km.

However, even on the BRO’s Golden Jubilee, an ambitious expansion of India’s border road network remains stymied by archaic laws and a crippling lack of urgency. The challenge before the BRO—triggered by China’s dramatic expansion of road and rail links in Tibet—is the Strategic Accelerated Road Development Programme (SARDP) planned by the Ministry of Road Transport and Highways. Under this, the BRO will build double-lane roads from each State capital in the north-east to each of that State’s district headquarters. That involves building 38 roads, approximately 2,812 km long, within the next five years. In addition, the government has recently handed the BRO responsibility for the Arunachal Package, which involves building another 812 km of roads in the State that China calls “Southern Tibet”.
