PANAJI, September 6-Black thick tar balls that surfaced in various beaches in Goa will now be sent to oil refineries to avoid further pollution.Goa Tourism minister Nilkant Halarnkar said, “truck loads of tar balls collected from several beaches in Goa will be sent to refineries instead of disposing them off in open fields or elsewhere.”“Although the National Institute of Oceanography (NIO) has said that these tar balls will not create any pollution as they are made of petroleum products but still we are not taking any chances,” he told reporters here on Sunday.The minister said tar balls surfacing on the coastal state’s beaches was an annual phenomenon but this time, their presence was much more.Majority of beaches were hit with tar balls which began appearing since last Monday and continued for a week. The worst affected were beaches in South Goa.Halarnkar said the state has roped in the Coastguard, Navy and NIO to go deep into the issue.“Some ship had mischievously dumped oil in the sea off Goa coast in the international waters which had washed ashore,” the minister said.Halarnkar said since the state government has no control over international waters, the issue needs to be sorted out with the help of defence forces, who keep vigil in high seas.He said the tar ball phenomenon will have no impact on the tourism season that will begin from October.

Climate change may lead to decline in bee pollination

WASHINGTON, September 6-A new study has indicated that decline in the population of bees and other flower-visiting animals may also lead to decline in pollination.A recent University of Toronto study provides the first long-term evidence of a downward trend in pollination, while also pointing to climate change as a possible contributor.“Bee numbers may have declined at our research site, but we suspect that a climate-driven mismatch between the times when flowers open and when bees emerge from hibernation is a more important factor,” said James Thomson, a scientist with U of T’s Department of Ecology and Evolutionary Biology.Thomson’s 17-year examination of the wild lily in the Rocky Mountains of Colorado is one of the longest-term studies of pollination ever done. It reveals a progressive decline in pollination over the years, with particularly noteworthy pollination deficits early in the season. Three times each year, Thomson compared the fruiting rate of unmanipulated flowers to that of flowers that are supplementally pollinated by hand. “Early in the year, when bumble bee queens are still hibernating, the fruiting rates are especially low,” he said. “This is sobering because it suggests that pollination is vulnerable even in a relatively pristine environment that is free of pesticides and human disturbance but still subject to climate change.” The study has been published in Philosophical Transactions of the Royal Society B: Biological Sciences.

ISRO to attempt key test for new generation rocket on Sep 8

BANGALORE, September 3-After a failed test six months ago, ISRO is making a fresh attempt on Wednesday to conduct long-duration static test of a crucial liquid core stage for a new generation heavy rocket which is being developed. “The static test of crucial liquid core stage (L110) of GSLV Mk III launch vehicle (rocket) for 200 seconds is slated for 3 pm on September eight,” a senior Indian Space Research Organisation (ISRO) official told PTI here. A top ISRO team, including Director of ISRO’s Liquid Propulsion Systems Centre (LPSC) S Ramakrishnan and Director of Vikram Sarabhai Space Centre (VSSC) P. S. Veeraraghavan, held a review meeting in Mahendragiri in Tamil Nadu yesterday and gave the go-ahead for the test. Chairman of Bangalore-headquartered ISRO, K Radhakrishnan, is expected to witness the test at LPSC test facility in Mahendragiri, officials said. ISRO conducted the test for 150 seconds at LPSC test facility on March five. While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters - minor leakage in the command system - was observed. A small leak in the command line was detected by computer, which automatically aborted the test. About 500 important parameters were monitored during the static test. ISRO has since analysed the data. GSLV Mk III rocket is being developed for launching four-tonne class of satellites in Geo-synchronous Transfer Orbit (GTO). Measuring 17 metres in length and four metres in diameter, L110 is an earth storable liquid propellant stage with propellant loading of 110 tonnes. L110 stage uses two high-pressure Vikas engines in a clustered configuration and draws its heritage from the second stage of PSLV and GSLV and strapons of GSLV. While in PSLV and GSLV, the liquid stage with single engine configuration burns for 150 seconds, the GSLV-Mk III requires burning for 200 seconds in a twin engine configuration. India’s PSLV and GSLV so far used one Vikas engine. But the heavy-rocket GSLV Mk III under development needs much better thrust. And hence, two Vikas engines were being used for the first time, they said. ISRO has already successfully conducted the short-duration static test of the L110 stage, which uses two high-pressure Vikas engines in a clustered configuration. In January this year, ISRO also successfully conducted static test of its largest solid booster S200, which would form the strap-on stage for the GSLV Mk III, at Satish Dhawan Space Centre (SDSC), Sriharikota. The successful test of S200 made it the third largest solid booster in the world, next to the RSRM solid booster of Space Shuttle and P230 solid booster of ARIANE-5.

Celebrating the monsoon

August 22-Normally the land frontier defines the contours of a country but the vastness of its seas and oceans open up wider horizons and the possibilities of voyages to other shores and cultures. The sea becomes the end point and the buffer zone of the national compass. The cloud-making seas, fed in turn by many types of global rains, divide and create a distance. Yet, at the same time, the invisible sea lanes lead us beyond boundaries of the border. It is not surprising that the Malabar coast became a leading trade hub and a vibrant passage of cross-cultural mergers and dialogues. It is also the place where the monsoons hit mainland India first…Technically, of course, the monsoons first hit the Andaman and Nicobar Islands but they are too remote in distance and national awareness, so the prize goes to Kerala. The gusts of wind that herald rain bend and break the coconut trees, which are very weak or too stiff and upright, but the more flexible ones bend and extend their palm leaves to break the downpour and so many tiny waterfalls hang out from their branches. The tropical green acquires a shine and gloss with a rich dark tinge. In Eastern philosophies, the strong and wise person's attribute of skilful resilience is often compared to the bamboo tree or reeds of grass that, unlike big firm trees, can bend with the wind and rain to survive better. On the Kerala coast in Varkala, the swirling grey waves rise to hit the red cliffs, unable to sweep their tongues inland.Perhaps the most wonderful place to watch the onset of the monsoons is Kanyakumari in Tamil Nadu, bordering Kerala. At the very edge of South India, one is exposed to two seas merging into the Indian Ocean. The monsoon sky is lit with the mystical mix of the declining sunlight and the rising moonshine, refracted by the prism of puffy nimbus clouds which play hide and seek with the sun and moon. The sea heaving and swelling with the downpour reflects the turbulence of the dark clouds. A long line of pilgrims of sectarian colours wait patiently outside the Kanyakumari temple, hoping for a miracle of the ‘ darshan'. Outside the temple, another miracle is happening; the miracle of nature, of water and sky, wind and light, thunder and lightning. The whole nation holds its breath, awaiting the announcement.Like the self-sufficiency in food while mass hunger continues in many parts, it is another great contradiction of India that there is too much water in some areas while droughts prevail in others. Distribution is the key word in both cases. Meanwhile, traditional and local water management practices, which sustain the most deprived in remote areas, are ignored and damaged by ‘modern development'.

Indigenous systems

I had to pass through some of the highest mountains passes to reach Ladakh which is too high for the monsoon clouds. The sun is sharp through the thin air and the horizon stretches across the barren slopes, magnifying the sense of space. The snow from the glaciers melts in little streams down the valley to be collected and shared cooperatively and circulated among high and low villages in one of the most developed traditional systems of water self-management, complete with water umpires, water spirits and magical stones that divert water. It is the tourist season and Ladakh is a dry and ‘hot' destination. Winter festivals are rearranged for the tourists who are escaping too much rain in the mountains and too much warm humid mess in the plains.

One of my earliest childhood memories is of Cherrapunji. A split bamboo pipe ran around the house to collect rain. I only knew that the water, in the kitchen and bathroom, came magically from nowhere. With deforestation and climate changes, some meteorologists think that Dharamsala, along with Darjeeling and Sikkim, has taken over from Cherrapunji as one of the rain centres of the world. During the monsoon, people are forced to do retreats indoors and contemplate on the streaming drops. This is the place to invent rain meditation with the assured background mantra chant of slow, chattering, wild thundering, rain, to explore equivalent levels of consciousness and also patience. The monks and nuns put up rainbow-coloured umbrellas on the maroon clothes. The beggars huddle with the dogs in the last dry corners. The crystal clear water of the Bagsu turns ugly brown with floating tourist plastic bottles. There is water everywhere but not a drop to drink in the tap.

I lived in Holland for two years or nearly eight drizzly seasons with two long winters in between. The rain there, like in that part of Europe, is slow but cold, grey, depressing and unpredictable in any season. There is no song and dance to celebrate it like the monsoon festivals, romance and music in India. I got depression living in artificial ‘Philips' light, which doctors recognise as a disease caused by lack of sunlight. Holland can only be a second home. India is first home if only because of a soul, which has grown up with the changing bright seasons and the mountain escape in summer.

The Dutch try to make up for the grey skies by their good cheer, openness and a friendly international, outlook. They live in small houses with big cosy (‘gezeluk') spirit. More than any other people they have conquered and harnessed the forces of water, both rain and sea. The land is low, making outlet difficult and now machines to pump the water up. India can learn from the Dutch to build a better and vast network of canals and small dams to store and circulate excess rain to dry areas.

In England, almost everything appears grey or dark; the misty air, umbrellas, clothes, hats and taxis. In Aberdeen, Scotland, even the houses are made up of grey stone. The rain interrupts sunsets and Wimbledon matches. It is amazing that a sunny game like cricket was invented in England, where it is so difficult to complete a full day's play, let alone a five-day test without rain. In Germany, the rain is sometimes called ‘acid' because it contains dirt of the skies. The business capital of the world, New York, has perhaps the most air-conditioned automatic banking centres where I found many homeless Afro-Americans sheltering form the rain and cold.

Better prepared

On the Trans-Siberian train from Moscow to Beijing, as soon as we crossed the Russian-Chinese Manchurian border, it started drizzling. Large Chinese families got in, marking the most dramatic change in weather, people, buildings and food. While the Russians sipped coffee or vodka, the Chinese guzzled big flasks of green tea. On the train from Beijing to Hanoi in southern China, it was the time of one of the worst floods. There was water everywhere. Some people were killed and hurt and communications disturbed. But the trains were running and there was not the massive disaster as in India, where hundreds of people are killed and thousands displaced. One wonders if the Chinese are better at evacuation, relief and drainage. The Yellow River was muddy brown and bursting at the seams but not as vast and violent as the Brahmaputra during the monsoons. There were little lakes everywhere and in the middle rose many tiny but steep hills like in a child's drawing. The mist hung in patches on the hilltops and along the pools in a space of stillness. It was a picture of a dream, charming; belonging to another world.

In Rajasthan where I grew up with the changing seasons, hopefully it will rain well, although the prospects are not very good. The sheep, goat and cattle-herding nomads and migrant workers will get news of ‘choko zamano', literally ‘good world' but also meaning good rain. They will hurry back to their lands to sow seeds. The ‘nadis', ponds and dams, will hopefully be full. It will be time for festivals. The biggest one rated, as one of the most colourful in the world, will be celebrated in Pushkar around the most sacred pool of water in full moon. The pool was created by Brahma, the cosmic creator himself. The villagers and pilgrims do not come to say prayers to the gods in the temples. They come to worship the water itself: the life sustaining element created by the harmonies of nature

Persistent plume found

WASHINGTON, August 22-The persistence of a giant plume of oil in the Gulf of Mexico suggests that the long-term impact of the BP Deepwater Horizon spill may be worse than earlier assumed, a new scientific study has revealed.In the latest issue of Science magazine, researchers at the Woods Hole Oceanographic Institution (WHOI) discussed their investigations of a plume of hydrocarbons at least 22 miles long and more than 3,000 feet below the surface. According to Christopher Reddy, a WHOI marine geochemist and oil spill expert, “The plume was not a river of Hershey’s Syrup... But that’s not to say it isn’t harmful to the environment.”

Doubts on earlier claims:Their discovery has cast doubt upon earlier claims by government agencies such as the National Oceanic and Atmospheric Administration (NOAA), which said that 74 per cent of the oil that gushed into the Gulf between April and August was either captured directly at the Macondo well site, had naturally evaporated or had been dispersed by operations at the surface and dissolved into microscopic droplets.According to the most recent study, the 1.2-mile-wide, 650-foot-high plume of trapped hydrocarbons provided at least a partial answer to recent questions asking where all the oil had gone as surface slicks shrank and disappeared. Mr. Reddy said, “These results indicate that efforts to book-keep where the oil went must now include this plume.”The WHOI study also disputed official estimates of the speed at which deep-sea microbes were degrading the plume. The plume has shown that the oil already “is persisting for longer periods than we would have expected”, according to Richard Camilli, Chief Scientist at WHOI and lead author of the paper. He added, “Many people speculated that subsurface oil droplets were being easily biodegraded. Well, we didn’t find that. We found it was still there.”The WHOI study was based on approximately 57,000 discrete chemical analyses undertaken during a June 19-28 scientific cruise. The expedition entailed the use of two highly advanced technologies: the autonomous underwater vehicle and an underwater mass spectrometer.While the WHOI scientists noted that they had found no “dead zones”, or regions of significant oxygen depletion within the plume where marine life could not survive, WHOI geochemist Benjamin Van Mooy, said this finding could have significant implications.

“If the oxygen data from the plume layer are telling us it isn’t being rapidly consumed by microbes near the well,” he said, “the hydrocarbons could persist for some time. So it is possible that oil could be transported considerable distances from the well before being degraded.”

Earthquakes have rocked the powerful San Andreas fault that splits California far more often than previously thought

E-mail Print PDF

 (Aug. 21, 2010) — Earthquakes have rocked the powerful San Andreas fault that splits California far more often than previously thought, according to UC Irvine and Arizona State University researchers who have charted temblors there stretching back 700 years.

The findings, to be published in the Sept. 1 issue of Geology, conclude that large ruptures have occurred on the Carrizo Plain portion of the fault -- about 100 miles northwest of Los Angeles -- as often as every 45 to 144 years. But the last big quake was in 1857, more than 150 years ago.

UCI researchers said that while it's possible the fault is experiencing a natural lull, they think it's more likely a major quake could happen soon. "If you're waiting for somebody to tell you when we're close to the next San Andreas earthquake, just look at the data," said UCI seismologist Lisa Grant Ludwig, principal investigator on the study.

An associate professor of public health, she hopes the findings will serve as a wake-up call to Californians who've grown complacent about the risk of major earthquakes. She said the new data "puts the exclamation point" on the need for state residents and policymakers to be prepared.

For individuals, that means having ample water and other supplies on hand, safeguarding possessions in advance, and establishing family emergency plans. For regulators, Ludwig advocates new policies requiring earthquake risk signs on unsafe buildings and forcing inspectors in home-sale transactions to disclose degrees of risk.

Sinan Akciz, UCI assistant project scientist and the study's lead author, was part of a team that collected charcoal samples from carefully dug trenches in the Carrizo Plain, along with earlier samples that Ludwig had stored for decades in her garage. The charcoal forms naturally after wildfires, then is washed into the plain by rains, building up over the centuries in layers that are fragmented during earthquakes. Akciz dated the samples via recently developed radiocarbon techniques to determine time frames for six major earthquakes, the earliest occurring about 1300 A.D.

The field data confirmed what Ludwig had long suspected: The widely accepted belief that a major earthquake happened on the fault every 250 to 400 years was inaccurate. Not all quakes were as strong as originally thought, either; but they all packed a wallop, ranging between magnitude 6.5 and 7.9.

"What we know is for the last 700 years, earthquakes on the southern San Andreas fault have been much more frequent than everyone thought," said Akciz. "Data presented here contradict previously published reports."

"We've learned that earthquake recurrence along the San Andreas fault is complex," agreed co-author Ramon Arrowsmith, a geology professor at Arizona State. "While earthquakes may be more frequent, they may also be smaller. That's a bit of good news to offset the bad."

Ken Hudnut, a geophysicist with the U.S. Geological Survey, said the research is significant because it revises long-standing concepts about well-spaced, extremely strong quakes on the 810-mile fault.

"I believe they've done a really careful job," he said, adding that the work was rigorously field-checked by many scientists. "When people come up with new results challenging old notions, others need to see the evidence for themselves."

Upending previous San Andreas fault modeling is part of a broader shift in seismic research. Experts are increasingly tracking webs of trigger points, smaller faults and more frequent quakes rather than focusing on large, single faults where they assumed there would be well-spaced shakers.

As for the 153-year hiatus since the magnitude 7.8 Fort Tejon quake, Ludwig said: "People should not stick their heads in the ground. There are storm clouds gathered on the horizon. Does that mean it's definitely going to rain? No, but when you have that many clouds, you think, 'I'm going to take my umbrella with me today.' That's what this research does: It gives us a chance to prepare."

Funding for the study was provided by the National Science Foundation, U.S. Geological Survey and Southern California Earthquake Center.

Scientist IDs Genes That Promise to Make Biofuel Production More Efficient, Economical

E-mail Print PDF

 (Aug. 19, 2010) — A University of Illinois metabolic engineer has taken the first step toward the more efficient and economical production of biofuels by developing a strain of yeast with increased alcohol tolerance.

Biofuels are produced through microbial fermentation of biomass crops, which yield the alcohol-based fuels ethanol and iso-butanol if yeast is used as the microbe to convert sugars from biomass into biofuels.

"However, at a certain concentration, the biofuels that are being created become toxic to the yeast used in making them. Our goal was to find a gene or genes that reduce this toxic effect," said Yong-Su Jin, an assistant professor of microbial genomics in the U of I Department of Food Science and Human Nutrition and a faculty member in the U of I's Institute for Genomic Biology.

Jin worked with Saccharomyces cerevisiae, the microbe most often used in making ethanol, to identify four genes (MSN2, DOG1, HAL1, and INO1) that improve tolerance to ethanol and iso-butanol when they are overexpressed.

"We expect these genes will serve as key components of a genetic toolbox for breeding yeast with high ethanol tolerance for efficient ethanol fermentation," he said.

To assess the overexpressed genes' contribution to the components that have limited biofuel production, the scientists tested them in the presence of high concentrations of glucose (10%), ethanol (5%), and iso-butanol (1%) and compared their performance to a control strain of S. cerevisiae.

Overexpression of any of the four genes remarkably increased ethanol tolerance, but the strain in which INO1 was overexpressed elicited the highest ethanol yield and productivity -- with increases of more than 70 percent for ethanol volume and more than 340 percent for ethanol tolerance when compared to the control strain.

According to Jin, the functions of the identified genes are very diverse and unrelated, which suggests that tolerance to high concentrations of iso-butanol and ethanol might involve the complex interactions of many genetic elements in yeast.

"For example, some genes increase cellular viability at the expense of fermentation. Others are more balanced between these two functions," he said.

"Identification of these genes should enable us to produce transportation fuels from biomass more economically and efficiently. It's a first step in understanding the cellular reaction that currently limits the production process," he said.

Further study of these genes should increase alcohol tolerance even further, and that will translate into cost savings and greater efficiency during biofuel production, he added.

Ready for Robot?

August 13-As the swanky car glides into his office compound, I look at my watch. “We'll meet at 4.30,” director Shankar had said. And, he is on the dot. Is this stickler-for-time approach one of the reasons for his rise from strength to strength? “Do I have a choice?” he laughs. “If you have to win, you must be willing to slog it out in meticulous fashion. As for punctuality, you should have seen Rajini at work,” he smiles. For an 8.30 schedule, he was always among the first to arrive at the spot. Charisma and popularity sit lightly on him. Surely he's one of the most comfortable heroes I've worked with.” Endhiran, the country's first sci-fi attempt, and the costliest Indian film ever, has taken nearly two years to make! “Considering the magnitude of the project, the time span is very less. Careful planning at the pre-production level helped us accomplish it,” says Shankar. He began working on Endhiran within a month of the release of Sivaji, and left for shooting only the following year after all arrangements were in place.But, the plot of Endhiran had germinated in his mind a decade ago. “Yes, we even did a photo shoot with Kamal Haasan and Preity Zinta. But, for various reasons, it got shelved. The story is the same, but once the hero was decided upon I spruced up the screenplay with Rajini's pluses to make it a treat for his fans,” smiles Shankar. Deliberating on the cost involved, Shankar thought he would make it in Hindi. But, after the stupendous success of Sivaji he realised the viability of a Rajinikanth film. If his credibility as a director and the Rajini factor came together again, Endhiran would emerge unassailable, he felt.

Completely original

Where did the inspiration for Endhiran come from? “From within me,” he says. And, a little piqued by the poser, adds: “I've worked hard on every shot so that it doesn't bear even an iota of resemblance to anything you've ever watched before.” Shankar's work has harvested plaudits from Hollywood technicians, who have worked on the visual effects of Endhiran. “The line is so original,” they had chorused. Shankar has handled diverse themes, from pedestrian fantasy to larger-than-life projections. “So, why not a robot, I thought. The result is Endhiran. I can't repeat myself. I need challenges all the time,” he says.

Endhiran'smind-boggling budget must be keeping him on tenterhooks. “Not at all, because I know it'll fetch the investment and more. If you have a fresh subject, a saleable cast and entertaining features in good measure, and top it with a small message, you cannot but hit the bull's eye. Credit should go to producer Kalanidhi Maran; the confidence he has reposed in me is remarkable. Also, Endhiran will transcend language barriers,” avers the maker. The film, which will be released in Tamil, Telugu and Hindi, is also being subtitled in English.The Bachchan bahu should be another promising scorer for Endhiran. “Surely, Aishwarya Rai is a significant part of the ‘E' factor. And, she is as dedicated and hardworking as a hero,” says Shankar. The storehouse of talent and beauty has come a long way as an actor since the days of Jeans, her first film with Shankar. “She needed to be taught things then,” remembers Shankar. “But now, she's a veteran who performs on cue. And, it's superfluous to talk about her mesmerising screen presence.”

Moving on to another asset of Endhiran, composer A.R. Rahman, Shankar says with a smile: “We share a perfect rapport. Our understanding is so good that just looking at me he knows whether I like a tune or want something more.” Their association goes back to Shankar's debut, Gentleman.

The imposing list of technicians features lensman Ratnavelu, late writer Sujatha and art director Sabu Cyril. “Sabu has come up with some splendid creations in the form of futuristic sets and robotic labs,” he says. Shankar cannot forget Sujatha's contribution either. “Being well-versed in the subject, his inputs forEndhiran have been incredible.” After Sujatha passed away, Shankar and Karky took over and completed the rest of the dialogue.Endhiran will be a stunning visual experience … I hope,” he concludes, even as his eyes twinkle with confidence.

New study measures global warming effect on ecosystems

E-mail Print PDF
LOS ANGELES, August 9-Less than 20 per cent of plants and animal species in the world's tropical forests may remain in their current form by the end of the century due to global warming, a new study says.The study was conducted by Carnegie Institution's Department of Global Ecology and published in Conservation Letters, a journal of the Society for Conservation Biology Thursday.According to the new study, by 2100, only 18 to 45 percent of the plants and animals making up ecosystems in global humid tropical forests may remain as we know them today because of global warming.

In Latin America and Africa, about two-thirds of the humid tropical forests' biodiversity could alter because of climate change, selective logging and ongoing land-use changes.

In Asia and the central and southern Pacific islands, deforestation and logging are also the primary drivers of ecosystem changes.

The scientists came to the conclusion after looking at land use and climate change by integrating global deforestation and logging maps from satellite imagery and high-resolution data.

“This is the first global compilation of projected ecosystem impacts for humid tropical forests affected by these combined forces,” the institution’s Greg Asner said.

“For those areas of the globe projected to suffer most from climate change, land managers could focus their efforts on reducing the pressure from deforestation, thereby helping species adjust to climate change, or enhancing their ability to move in time to keep pace with it,” he said.

Tropical forests hold more than half of all the plants and animal species on earth. But the combined effect of climate change, forest clear cutting and logging may force them to adapt, move, even die.
