IISC scientist wins National Research Development Corporation award

BANGALORE: Forty-six-year-old principal research scientist of Indian Institute of Science's High Voltage Laboratory, Dr Subba Reddy B, has been awarded the prestigious National Research Development Corporation ( NRDC) Meritorious Societal Invention National Award by the Union Ministry of Science & Technology, which he is to receive next month.

He won the award for his work on insulators used in high voltage transmission line. His work helped enhance the pollution/contamination flashover strength of ceramic/porcelain insulators used in high voltage transmission lines.

There are three types of transmission lines currently used in India - porcelain/ceramic, glass and composite. The latter is a newly introduced phenomenon in the country though it's hugely popular in the West.

"Many form of contamination spreads on the surface of insulators because of various reasons. For instance if the insulators are near sea there's a gradual accumulation of salt, if near an industrial area, pollution is a big deterrent and so is water as a result of rains and fog," said Reddy.

"This results in the reduction of properties of insulators, leading to blackouts," he said.

Dr Subba Reddy B has been with the Indian Institute of Science for about two decades now, first as a student and then as a faculty member.

"I had an idea that could address the insulator problem in high voltage transmission line about a decade back. But, it was only in 2005 that I started working on them, both theoretically and practically," Reddy said.

My inspiration had been the people approaching the institute and me expressing their concerns about the insulator problem that resulted in frequent power cuts in the country, he added.

The gadget developed by Subba Reddy, to replace porcelain/ceramic insulators, most commonly used in high voltage transmission line in India, eliminates the flashover and thus reduces the blackouts to minimum.

It is made out of zinc and aluminum for experimental purposes, said Reddy.

"But, the metal of choice could be changed for industrial purposes," he added.

Currently, some of the big companies which deal insulators have approached IISC,, which holds the patent for the gadget since 2009.

"It's a long process which can take some time. So, we will have to wait for a few more years for the commercial manufacturing of the gadget," he added.

Deformed Dolphin Accepted Into New Family

In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic news).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Pentagon to Allow Women in Combat

Defense Secretary Leon Panetta will lift a longstanding ban on women serving in combat, according to senior defense officials.

The services have until this May to come up with a plan to implement the change, according to a Defense Department official.

That means the changes could come into effect as early as May, though the services will have until January 2016 to complete the implementation of the changes.

"We certainly want to see this executed responsibly but in a reasonable time frame, so I would hope that this doesn't get dragged out," said former Marine Capt. Zoe Bedell, who joined a recent lawsuit aimed at getting women on the battlefield.

The military services also will have until January 2016 to seek waivers for certain jobs -- but those waivers will require a personal approval from the secretary of defense and will have to be based on rationales other than the direct combat exclusion rule.

The move to allow women in combat, first reported by the Associated Press, was not expected this week, although there has been a concerted effort by the Obama administration to further open up the armed forces to women.

The Joint Chiefs of Staff unanimously recommended in January to Secretary Panetta that the direct combat exclusion rule should be lifted.

"I can confirm media reports that the secretary and the chairman are expected to announce the lifting of the direct combat exclusion rule for women in the military," said a senior Defense Department official. "This policy change will initiate a process whereby the services will develop plans to implement this decision, which was made by the secretary of defense upon the recommendation of the Joint Chiefs of Staff."

Chairman of the Joint Chiefs Gen. Martin Dempsey sent Panetta a memo earlier this month entitled, "Women in Service Implementation Plan."

"The time has come to rescind the direct combat exclusion rule for women and to eliminate all unnecessary gender-based barriers to service," the memo read.

"To implement these initiatives successfully and without sacrificing our warfighting capability or the trust of the American people, we will need time to get it right," he said in the memo, referring to the 2016 horizon.

Women have been officially prohibited from serving in combat since a 1994 rule that barred them from serving in ground combat units. That does not mean they have been immune from danger or from combat.

As Martha Raddatz reported in 2009, women have served in support positions on and off the frontlines in Iraq and Afghanistan, where war is waged on street corners and in markets, putting them at equal risk. Hundreds of thousands of women deployed with the military to those two war zones over the past decade. Hundreds have died.

"The reality of the battlefield has changed really since the Vietnam era to where it is today," said Rep. Tammy Duckworth, D-Ill., a former military helicopter pilot who lost both her legs in combat. "Those distinctions on what is combat and what is not really are falling aside. So I think that after having seen women, men, folks who -- cooks, clerks, truck drivers -- serve in combat conditions, the reality is women are already in combat."

Woman have been able to fly combat sorties since 1993. In 2010, the Navy allowed them on submarines. But lifting restrictions on service in frontline ground combat units will break a key barrier in the military.

Panetta's decision will set a January 2016 deadline for the military service branches to argue that there are military roles that should remain closed to women.

In February 2012 the Defense Department opened up 14,500 positions to women that had previously been limited to men and lifted a rule that prohibited women from living with combat units.

Panetta also directed the services to examine ways to open more combat roles to women.

However, the ban on direct combat positions has remained in place.

Unilever reports 5.0% profit rise to 4.48b euros

THE HAGUE: Global food and cosmetics giant Unilever reported on Wednesday that net profit last year rose by 5.0 per cent from the 2011 level to 4.48 billion euros (US$5.96 billion).

Unilever, which achieved sales exceeding 50 billion euros for the first time with a figure of 51.3 billion euros, up 10.5 per cent, said the outcome was an important step towards its target of sales of 80 billion euros.

"There is no room for complacency," Unilever chief executive Paul Polman nevertheless warned in a statement.

"Markets will remain challenging, with intense competition and volatile commodity costs."

"We remain focused on achieving another year of profitable volume growth ahead of our markets, steady and sustainable core operating margin improvement and strong cash flow."

Unilever's fourth-quarter sales rose by 7.8 per cent, thanks largely to volume growth of 4.8 per cent, higher than the 6.3 per cent expected on average by analysts interviewed by Dow Jones Newswires.

Underlying sales growth in emerging markets was 11.4 per cent, representing 55.0 per cent of the multinational's global turnover.

"Emerging markets again contributed double-digit growth helping us exceed 50 billion euros turnover, an important milestone in our journey to double the size of Unilever from 40 billion euros to 80 billion euros whilst reducing our environmental impact," Polman said.

The company saw strongest sales growth in Asia-Africa, where the figures rose by 10.6 per cent, while Americas sales were up 7.9 per cent.

Performance in Europe was "sluggish", the company said, with sales up 0.8 per cent.

This reflects "the fragile state of consumer confidence and intensely competitive markets," Unilever said.

Nevertheless, "we have responded to the needs of hard-pressed consumers by providing good quality products at low price points."

"Throughout 2012 our markets experienced markedly different dynamics as emerging markets grew in both volume and value terms whilst developed market value remained subdued, with volumes lower than prior year," Unilever said.

The Anglo-Dutch company said that Magnum ice creams and Sunsilk hair products had become "billion-euros brands", bringing the company's total of such brands to 14.

"We continued to invest behind our brands, again increasing advertising and promotions spend," Polman said, with such spending up 470 million euros.

One of the world's leading suppliers of consumer goods, Unilever owns a wide variety of brands including Knorr, Lipton, Dove and Vaseline. It employs 167,000 workers in 100 countries.

Rajnath Singh elected unopposed as BJP president

NEW DELHI: Newly-elected Bharatiya Janata Party chief Rajnath Singh defended his predecessor, saying Nitin Gadkari opted against a second term due to the "baseless allegations" made against him.

"The circumstances in which I accept this responsibility are not happy for us. Gadkari is one of our workers on whose character questions cannot be raised," Rajnath Singh said speaking soon after becoming the new party president on Wednesday.

"We wanted him to continue. We amended the constitution for it... But the way he was attacked by baseless allegations - he was hurt and resigned," he said.

"I want to tell him that the entire party stands with him. I am not accepting this as a post but as a responsibility," Rajnath Singh added.

Nitin Gadkari, who was all set for a second term, had to step down at the last moment after on-field investigation by income tax department in some companies allegedly related to the Purti Group, to which he is reportedly related.

Gadkari congratulated Rajnath Singh even as he denied any wrongdoing.

"I congratulate him (Rajnath Singh). I have worked under his leadership... He has the ability to make us win the 2014 election under his leadership," Gadkari said in a speech here.

"As far as the election for a second term is concerned, there had been attempts through a political conspiracy to link me to an issue I was not related to," Gadkari said, referring to the allegations of corruption against him.

Earlier, Rajnath Singh was elected unopposed as the president of the party after he filed nomination papers for the post.

A resolution supporting Rajnath Singh as the BJP chief was unanimously adopted by the parliamentary board of the party, after which he filed his nomination papers.

The returning officer announced that 17 other nominations were also filed in Rajnath Singh's favour.

Rajnath Singh has previously been the president of the party from 2005 to 2009. He first became the party president in December 2005, following the resignation of LK Advani.

Rajnath Singh and incumbent Nitin Gadkari arrived at the party office in the same car for a meeting of the party's parliamentary board, after which he filed his nomination.

On Tuesday, after rapid and dramatic developments, BJP junked Nitin Gadkari as its presidential nominee and instead zeroed in on former party chief and UP leader Rajnath Singh to lead the party in the run up to the 2014 elections.

The Promise and Perils of Mining Asteroids

Encouraged by new space technologies, a growing fleet of commercial rockets and the vast potential to generate riches, a group of entrepreneurs announced Tuesday that they planned to mine the thousands of near-Earth asteroids in the coming decades.

The new company, Deep Space Industries (DSI), is not the first in the field, nor is it the most well-financed. But with their ambition to become the first asteroid prospectors, and ultimately miners and manufacturers, they are aggressively going after what Mark Sonter, a member of DSI's board of directors, called "the main resource opportunity of the 21st century." (Related: "Asteroid Hunter to Be First Private Deep-Space Mission?")

Prospecting using miniaturized "cubesat" probes the size of a laptop will begin by 2015, company executives announced. They plan to return collections of asteroid samples to Earth not long after.

"Using low cost technologies, and combining the legacy of [the United States'] space program with the innovation of today's young high tech geniuses, we will do things that would have been impossible just a few years ago," said Rick Tumlinson, company chairman and a longtime visionary and organizer in the world of commercial space [not sure what commercial space means].

"We sit in a sea of resources so infinite they're impossible to describe," Tumlinson said.

Added Value

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.

Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing. (See an interactive on asteroid mining.)

Sonter, an Australian mining consultant and asteroid specialist, said that 700 to 800 near-Earth asteroids are easier to reach and land on than the moon.

DSI's prospecting spacecraft will be called "FireFlies," a reference to the popular science fiction television series of the same name. The FireFlies will hitchhike on rockets carrying up communication satellites or scientific instruments, but they will be designed so that they also have their own propulsion systems. The larger mining spacecraft to follow have been named "DragonFlies."

Efficiencies

It all sounds like science fiction, but CEO David Gump said that the technology is evolving so quickly that a space economy can soon become a reality. Providing resources from beyond Earth to power spacecraft and keep space travelers alive is the logical way to go.

That's because the most expensive and resource-intensive aspect of space travel is pushing through the Earth's atmosphere. Some 90 percent of the weight lifted by a rocket sending a capsule to Mars is fuel. Speaking during a press conference at the Santa Monica Museum of Flying in California, Gump said that Mars exploration would be much cheaper, and more efficient, if some of the fuel could be picked up en route. (Related: "7 Ways You Could Blast Off by 2023.")

Although there is little competition in the asteroid mining field so far, DSI has some large hurdles ahead of it. The first company to announce plans for asteroid mining was Planetary Resources, Inc. in spring 2012—the group is backed by big-name investors such as Google's Larry Page and Eric Schmidt, filmmaker James Cameron, and early Google investor Ram Shriram. DSI is still looking for funding.

Owning Asteroids

While these potential space entrepreneurs are confident they can physically lay claim to resources beyond Earth, there remain untested legal issues.

The United Nations Space Treaty of 1967 expressly forbids ownership of other celestial bodies by governments on Earth. But American administrations have long argued that the same is not true of private companies and potential mining rights.

While an American court has ruled that an individual cannot own an asteroid—as in the case of Gregory Nemitz, who laid claim to 433 Eros as a NASA spacecraft was approaching it in 2001—the question of extraction rights has not been tested.

Moon rocks brought back to Earth during the Apollo program are considered to belong to the United States, and the Russian space agency has sold some moon samples it has returned to Earth-sales seen by some as setting a precedent.

Despite the potential for future legal issues, DSI's Gump said his group recently met with top NASA officials to discuss issues regarding technology and capital, and came away optimistic. "There's a great hunger for the idea of getting space missions done with smaller, cheaper 'cubesat' technology and for increased private sector involvement."

Everyone involved acknowledged the vast challenges and risks ahead, but they see an equally vast potential—both financial and societal.

"Over the decades, we believe these efforts will help expand the civilization of Earth into the cosmos, and change what it means to be a citizen of this planet," Tumlinson said.

Al Qaeda Commander Killed for the 3rd Time

The second in command of al Qaeda's Yemen affiliate was reportedly killed in an airstrike in Yemen in December, according to a news report by Arabic television network Al Arabiya, the third time the former Guantanamo detainee has been reported dead since 2010.

According to the report, Said al-Shihri died last month after sustaining severe injuries from a joint U.S.-Yemeni airstrike that targeted a convoy in which he was riding. The al Arabiya account, based on information from "family sources," said that the airstrike left al-Shihri in a coma. He allegedly died soon after and was buried in Yemen.

On Tuesday afternoon, hours after the initial report, a Yemeni government official denied having any information regarding the death of al-Shihri, according to Arabic news site al-Bawaba.

No photos of a body have yet surfaced and no mention of his death has appeared on jihadi forums.
This is the third time al-Shihri, the second in command of al Qaeda in the Arabian Peninsula (AQAP), has been reported killed since 2009. In 2010, the Yemeni government claimed it had captured him. In September 2012, Yemeni news sites reported he was killed in an American drone strike.

Al-Shihri, a "veteran jihadist," traveled to Afghanistan shortly after the Sept. 11, 2001 terror attacks to fight coalition troops, only to be captured weeks later, according to West Point's Combating Terrorism Center. He was sent to the U.S. prison in Guantanamo Bay, Cuba, where he stayed for six years before being released to Saudi Arabia. There, he entered a so-called "jihadi rehab" program that attempted to turn terrorists into art students by getting them to get "negative energy out on paper," as the program's director told ABC News in 2009.

But just months after he supposedly entered the fingerpainting camp, al-Shihri reappeared in Yemen where he was suspected to have been behind a deadly bombing at the U.S. embassy there.

At the time, critics of the "jihadi rehab" program used al-Shihri as evidence that extremists would just go through the motions in order to be freed.

At second inauguration, Obama relishes the rituals, as well as the smaller moments

The second time seemed to charm him.

The choreography of President Obama’s ceremonial inauguration Monday was nearly identical to that of his swearing-in four years ago: church, motorcade to the Capitol, invocation, oath, address, luncheon, parade, dancing.

This time, however, the man taking the oath of office was an experienced president, not a first-term senator. And Obama seemed determined to relish the rituals and have himself some fun.

In his public remarks, he spoke with conviction. From the Capitol steps, he asserted his intention to bind the nation closer together. He was sober in addressing members of Congress at a luncheon.

But the president also found joy in the smaller moments. He blew kisses as he walked the parade route with his jubilant wife, Michelle, beside him. He bobbed his head and grooved watching a drill group from Iowa pass by and waved the shaka sign to the marching band from his Hawaiian high school alma mater. On the dance floor later, he nuzzled his wife’s hair and crooned in her ear.

There was a majesty and gravity to Monday’s proceedings, but this time, unlike four years ago, Obama knows what his office demands, as well as the limits on its power. His life is not in transition like it was then. He is settled.

He seemed to recognize that the next time the country pauses to inaugurate a president, the Obamas will be moving out of the White House, departing the city by helicopter and heading home. After the ceremony on the Capitol steps, as the president headed inside, he turned back and stopped.

“I want to take a look, one more time,” Obama said. “I’m not going to see this again.”

He stood still and looked out at the panorama of flags waving and people, hundreds of thousands of them, cramming the Mall and chanting his name.

It was as if he wanted to engrave the picture on his mind.

And he seemed to savor such moments throughout the day.

When the Brooklyn Tabernacle Choir sang “The Battle Hymn of the Republic,” he turned and broadly winked at his daughters, Malia, 14, and Sasha, 11.

Myrlie Evers-Williams, a civil rights activist whose husband, Medgar Evers, was assassinated in 1963 in his Mississippi driveway, delivered the invocation. She spoke of being challenged by adversity — “For every mountain, you gave us the strength to climb,” she said — and Obama, his eyes closed in prayer, lifted his shoulders and took a deep breath.

“Amen,” he said at the end of her prayer.

A man behind the president shouted, “Hallelujah!”

When Chief Justice John G. Roberts Jr. delivered the president’s oath at 11:50 a.m., Obama flubbed a word, “the office of president of the United Sta—.” But it didn’t matter. He had recited the official oath correctly a day earlier, on Jan. 20, the inauguration date mandated by the Constitution. (His daughter Sasha already had congratulated him, too: “You didn’t mess up,” she told him in the Blue Room. )

Then, once Sen. Charles E. Schumer (D-N.Y.) introduced him as “the 44th president of the United States,” Obama looked down and smiled. He gathered himself and pushed his chin up, understanding his role in addressing the nation far more clearly than he could have the first time around.

Penguin head-cam captures bird's eye view of hunt

TOKYO: Miniature cameras attached to a penguin's head have given Japanese scientists a bird's eye view of the creature's incredible underwater hunting skills, the lead researcher said Tuesday.

Using video cameras weighing just 33 grammes (around 1 oz) and equipped with accelerometers, depth gauges and thermometres, researchers were able to see exactly what the Adelie penguin sees when it goes out to catch krill and other prey in its native Antarctica.

Yuuki Watanabe, of the National Institute of Polar Research in Tokyo, said the team was amazed to discover that the bird adapts its hunting behaviour depending on what it is trying to snare.

Watanabe said the accelerometer -- a device also used in mobile phones, tablet computers and games consoles -- allowed researchers to precisely measure the bird's head movements and showed how one penguin could catch two krill in under a second.

"Now we know what the Adelie penguin preys on and how much it eats, we can understand how the penguin survives and how it relates to its environment," he said.

The penguin's fragile Antarctic habitat is at risk from climate change, with scientists warning that as pack ice melts, their numbers could fall dramatically.

Watanabe said the tiny cameras and micro equipment had given researchers a much better understanding of how the penguin lives.

"We now understand how much they rely on those fish that inhabit water just below the sea ice, which means that Adelie penguins can only survive in a sea ice environment," said Watanabe.

Demands for Shinde's resignation unwarranted, Narayanasamy says

CHENNAI: Union minister V Narayanasamy said on Tuesday terrorism in any form was 'condemnable' and slammed demands for resignation of home minister Sushilkumar Shinde over his 'Hindu terrorism' remarks.

Shinde had only stated what was already reported in media in connection with the Malegaon and Mecca Masjid blasts, minister of state in the PMO told reporters at the airport.

"Demand for Shinde's resignation is unwarranted. Regarding the Malegaon and Mecca Masjid cases, some from a particular community were involved. Some training camps were found where there were some Hindu fundamentalists. The trial is now happening. He only mentioned what was happening," he said.

There was terrorism in several parts of the country and whoever is involved, it was "condemnable."

"Whether Hindu terrorism or Islamic terrorism, UPA government condemns both," he said.

Shinde had triggered a controversy at the AICC meet in Jaipur by accusing BJP and RSS of conducting terror training camps and promoting "Hindu terrorism." BJP has reacted strongly to the remarks, demanding his sacking while the RSS has dubbed him a "darling of real terrorists".

To a question, Narayanasamy said the Jayalalithaa-led state government was adopting a 'confrontational attitude' with Centre and warned this was not good for smooth relations.

"Without the support of the Centre, the state cannot grow, similarly the state (government's) support is needed for Centre also," he said in the wake of Jayalalithaa's strong criticism of UPA government on many issues.
