How life might evolve with “exotic” biochemistry and solvents

London, September 18 (ANI): Scientists at a new interdisciplinary research group in Austria are working to uncover how life might evolve with “exotic” biochemistry and solvents, such as sulfuric acid instead of water.

The research group for Alternative Solvents as a Basis for Life Supporting Zones in (Exo-) Planetary Systems was established by the University of Vienna.

Traditionally, planets that might sustain life are looked for in the ‘habitable zone’, the region around a star in which Earth-like planets with carbon dioxide, water vapor and nitrogen atmospheres could maintain liquid water on their surfaces.

Consequently, scientists have been looking for biomarkers produced by extraterrestrial life with metabolisms resembling the terrestrial ones, where water is used as a solvent and the building blocks of life, amino acids, are based on carbon and oxygen.

However, these may not be the only conditions under which life could evolve.

“It is time to make a radical change in our present geocentric mindset for life as we know it on Earth,” said scientist Johannes Leitner.

“Even though this is the only kind of life we know, it cannot be ruled out that life forms have evolved somewhere that neither rely on water nor on a carbon and oxygen based metabolism,” he added.

One requirement for a life-supporting solvent is that it remains liquid over a large temperature range.

Water is liquid between 0 degree Celsius and 100 degrees C, but other solvents exist which are liquid over more than 200 degrees C.

Such a solvent would allow an ocean on a planet closer to the central star.

The reverse scenario is also possible. A liquid ocean of ammonia could exist much further from a star.

Furthermore, sulfuric acid can be found within the cloud layers of Venus and it is now known that lakes of methane/ethane cover parts of the surface of the Saturnian satellite Titan.

Consequently, the discussion on potential life and the best strategies for its detection is ongoing and not only limited to exoplanets and habitable zones.

The newly established research group at the University of Vienna, together with international collaborators, will investigate the properties of a range of solvents other than water, including their abundance in space, thermal and biochemical characteristics as well as their ability to support the origin and evolution of life supporting metabolisms.

Earthquake insurance of houses in Assam

Guwahati, Sep 9 (ANI): As experts claim that a big earthquake might hit Assam region shortly, locals are rushing to get their houses insured while the authorities are conducting sensitization campaigns as a precautionary measure.

The region was rocked by four earthquakes in past three weeks, including a tremor with 5.9 magnitude, the biggest in past nine years in the area.

People are not just getting their houses insured but advising others to do so as well.

“We are advising other people in the (housing) society to insure their flats also so that we can fight such disasters together. Precaution is important at this time. People have become alert and there is a general atmosphere of fear that prevails,” said Ravishankar Ravi, a resident.

Even builders in the city are taking all precautions while constructing buildings. The last and the strongest of the recent four earthquakes have literally shaken the people.

“We are really concerned about the earthquake because in the last month, we have already had four earthquakes, it worried us a lot because we are staying in apartments and it becomes tough to manage while there is (constant fear) of earthquake going on. We are really worried because we have a history of major earthquake in 1950. And there are some rumours also going on that there might be a earthquake, a big earthquake might happen in the course of time,” said Adreena Bora, another resident.

Meanwhile the authorities are gearing up for any such situation as well. They are conducting sensitization and awareness campaigns across the city in schools, housing societies, government and corporate houses.

“We are having sensitization meetings amongst them (schools and societies). We are telling them, those who are living in multi storey buildings because they will be more vulnerable to damage because of an earthquake, as to what they should know about the quality of buildings and what they should do to minimize casualties like hiding or coming under a beam,’ said Pratik Hazele, Deputy Commissioner, Kamrup.

Assam is seated on the highly volatile seismic zone five. Among all the earthquakes that Assam has experienced, the earthquakes of 1897 and 1950 are among the ten biggest earthquakes in history.

Study reveals that Assam records a major earthquake every fifty years, the last being in 1950. (ANI)

MJ’s brother’s fury over ‘secret’ burial filming

London, September 6 (ANI): Michael Jackson’s brother Randy has slammed the “surreptitious” filming of the burial of the late star in Los Angeles.

The former ‘Jackson 5′ singer reacted after a camera kept filming the private ceremony at Glendale Forest Lawn Memorial Park on a hovering helicopter despite the area being a no-fly zone.

“I was dismayed last night and again today at the coverage I saw on television of our ceremony for Michael,” the BBC quoted him as saying.

“We had asked the media to respect the privacy and the sanctity of this event; to give us one moment of privacy to mourn as a family out of the public spotlight.

“Unfortunately, despite a no-fly zone around Forest Lawn, many media organisations decided to ignore our wishes.

“I therefore ask today that media organisations airing helicopter footage of the ceremony we held for my brother immediately pull that footage from their air and refrain from airing it in the future,” he added.

The King of Pop was finally laid to rest after he died of a lethal cocktail of prescription drugs on June 25.

The Los Angeles coroner ruled Jackson’s death as homicide. (ANI)

George Harrison’s widow in razor fence row

London, September 5 (ANI): Late Beatle George Harrison’s widow Olivia has been caught up in a planning row after a former television sitcom star alleged that a razor wire fence around her house almost killed his cat.

Rodney Bewes, who starred as Bob Ferris in Seventies television show ‘The Likely Lads’, said the fence posed pets with a dangerous threat and even made the neighbourhood looking like a “war zone”.

Olivia filed a planning application with South Oxfordshire District Council to replace the fence with an identical version, a move opposed by Bewes.

“My cat, Maurice, has been injured on that fence several times, once severing an artery that nearly killed him. It has cost me thousands in vets’ bills,” the Telegraph quoted Bewes as saying.

“There are several other cats – people’s pets – that have been practically gored on that fence, it’s that dangerous.

“It makes me sad when I come home to such a beautiful place and see this thing that makes it look like a war zone. If everybody had razor wire around their gardens can you imagine what it would look like?

“It doesn’t make it any more secure. The bottom half is wood and with a good crowbar you could get through it no problem,” Bewes added.

The Harrisons came up with the boundary in Henley-on-Thames, Oxfordshire, after a crazed intruder broke in and stabbed the late guitarist in 1999. (ANI)

Wanted Maoist leader arrested in Bihar

Gaya, Sep 5 (ANI): Bihar police arrested a Maoist leader, wanted in two-dozen cases of murder, robbery and kidnapping here on Friday.

Vinod Mehta alias Marandi was the founder of Revolutionary Communist Centre (RCC), officials said.

Marandi, along with two of his associates, was arrested from Sherghati town.

Officials said Marandi was earlier a self-styled commander of Maoist Communist Centre (MCC), before snapping ties and founding his own outfit.

“Earlier he was a sub-zonal commander of MCC. He snapped his links with MCC. When he got out of jail, he formed a new terrorist organisation called RCC (Revolutionary Communist Centre),” said Ranjan Kumar, deputy superintendent of police, Sherghati town.

The central government banned and formally labelled Maoist insurgents as a terrorist group, hoping it would give security forces more enforcement powers after the rebels briefly created a ‘liberated zone’ in Lalgarh region of West Bengal recently.

Some experts said the ban would have little impact in the battle against an estimated 22,000 Maoist combatants. (ANI)

Nuke Sub, Aircraft Carrier in Kalam’s vision 2020 for Andamans

Port Blair (Andaman and Nicobar Islands), Sep 4 (ANI): Former President Dr APJ Abdul Kalam on Friday unveiled a vision document for the strategic development of the Andaman and Nicobar Islands by the year 2020.

Inaugurating a national seminar on ‘Security and Development of the Andaman and Nicobar islands’ here, Dr Kalam said that a 250 mw nuclear power station on one of the islands would form the core of the development programme.

Dr Kalam said the islands being a vital part of the country’s Exclusive Economic Zone (EEZ), the Andaman and Nicobar Command (ANC) of the Integrated Defence Staff (IDS) would have “enhanced significance” in the next decade.

He further said that the ANC should have bases for static aircraft carrier and a nuclear,

Dr Kalam also called upon the Armed Forces to evolve an effective security plan for underneath the sea, at sea level and in air.

“The security plan which you evolve should ensure that there is no unauthorised occupation of the vacant islands,”said Dr Kalam.

Meanwhile, Commander-in-Chief of the ANC, Vice Admiral Vijay Shankar, said that the location of these islands confers a geostrategic advantage.

“Its economic and forest potential dictates a sound security presence,” he added.

Top defence and security experts, including Deputy National Security Advisor Shekhar Dutt, former Foreign Secretary Shyam Saran and Principal Scientific Advisor to the Government of India R Chidambaram, are attending the two-day seminar. (ANI)

MJ finally buried to rest in peace

London, Sep 4 (ANI): King of Pop Michael Jackson was finally been buried at the Forest Lane cemetery in Los Angeles, while the world media covered a part of the final service.

Almost two-dozen cars with members of Jackson family inside entered the gates of the cemetery about an hour late than the scheduled time.

Hollywood celebritiesm including Dame Elizabeth Taylor, Macaulay Culkin and Jackson’s ex-wife Lisa-Marie Presley, were waiting inside the memorial park along with 200 guests on white wooden chairs arranged outside one of the many ornate buildings on this site.rogrammes containing pictures of Michael Jackson were being played, while the guests were fanning themselves in the night heat.

After the family arrived, the ‘Thriller’ star’s mother Katherine and father Joe sat down in the front row, while his three children sat between their grandparents and an upset Janet Jackson.amily members wore black armbands and his brothers stood at the front, ready to repeat their roles as pall-bearers.

They had walked beside their brother’s coffin at the memorial service in July and did the same at the burial.

And after everyone was seated, Jackson’s coffin was driven in by hearse, unloaded and wheeled into place.

His three children walked up to it and gave a brief farewell after which the media was asked to switch off the cameras for a private service as per the family’s request.

The service lasted around an hour and cars departed swiftly.

Earlier in the day, police had sealed off part of the area and even enforced a no-fly zone to keep news helicopters from buzzing overhead.

They had warned fans to stay away. (ANI)

Railway gangman killed by train robbers in Bihar

Patna, Aug 30 (ANI): A railway employee was killed and 10 others were injured when an armed gang looted cash and valuables from passengers of Jhajha-Patna local train in Bihar’s Jamui district on early Sunday.

The incident took place in the East Central Railway zone.

According to police sources, armed robbers boarded the train at Jamui and went on a looting spree.

The robbers snatched cellular phones, cash and other valuables worth around Rs 1 lakh from the passengers, police sources added.

The railway gangman, Mukesh Mandal, was shot at when he tried to resist looters near Mahesh Leta station.

Mandal, who sustained serious wounds, died on the way to a hospital at Jamui, sources said.

At least 10 passengers were wounded in a stampede, which was created due to the fire by the robbers.

The robbers managed to escape after pulling the chain of the train near Mahesh Leta station.

The Railway Police and the Bihar state Police are conducting search operation in the area for the robbers. (ANI)

Unique acacia tree could nourish soils in Africa

Washington, August 25 (ANI): In a new research, scientists have said that a type of acacia tree with an unusual growth habit, which is unlike virtually all other trees, holds particular promise for farmers in Africa as a free source of nitrogen for their soils that could last generations.

With its nitrogen-fixing qualities, the tall, long-lived acacia tree, Faidherbia albida could limit the use of fertilizers; provide fodder for livestock, wood for construction and fuel wood, and medicine through its bark, as well as windbreaks and erosion control to farmers across sub-Saharan Africa.

According to scientists, the tree illustrates the benefits of growing trees on farms and is adapted to an incredibly wide array of climates and soils from the deserts to the humid tropics.

“Growing the right tree in the right place on farms in sub-Saharan Africa-and worldwide- has the potential to slow climate change, feed more people, and protect the environment,” said Dennis Garrity, Director General of the World Agroforestry Centre.

“This tree, as a source of free, organic nitrogen, is an example of that. There are many other examples of solutions to African farming that exist here already,” he added.

The Faidherbia acacia tree has the quality of “reverse leaf phenology,” which drives the tree to go dormant and shed its nitrogen-rich leaves during the early rainy season – when seeds are being planted and need the nitrogen – and then to re-grow its leaves when the dry season begins and crops are dormant.

This makes it highly compatible with food crops because it does not compete with them for light-only the bare branches of the tree’s canopy spread overhead while crops grow to maturity.

Their leaves and pods provide a crucial source of fodder in the dry season for livestock when other plants have dried up.

The unique acacia tree is a frequent component of farming systems of Senegal, Mali, Burkina Faso, Niger, Chad, Sudan, and Ethiopia, and in parts of northern Ghana, northern Nigeria, and northern Cameroon.

The tree is growing on over 4.8 million hectares of land in Niger. Half a million farmers in Malawi and in the southern highlands of Tanzania grow the tree on their maize fields.

In Malawi, maize yields were increased up to 280 percent in the zone under the tree canopy compared with the zone outside the tree canopy.

In Zambia, recent unpublished observations showed that unfertilized maize yields in the vicinity of the Faidherbia trees averaged 4.1 tonnes per hectare, compared to 1.3 tonnes nearby but beyond the tree canopy. (ANI)

Lalgarh scene of violence again by Maoists

Lalgarh, Aug 21 (ANI): A landmine blast and road blockades marked third day of shutdown call by Maoists in West Bengal.

Maoists gave an indefinite shutdown call on Tuesday in West Medinipur, Bankura and Purulia districts of the state, demanding withdrawal of security forces from Lalgarh and protesting alleged police excesses on villagers in tribal dominated areas.

A landmine exploded near a canal at Mohultala forest area of Maoist-infested Lalgarh region while paramilitary forces, patrolling nearby, defused three other landmines planted by suspected Maoists.

The landmine blast however caused no damage.

Traffic was disrupted as the roads were damaged at several places in the Lalgarh area.

“When I came here this morning I was shocked to see the entire road damaged, causing inconvenience to all. I am unaware since it must have happened at night,” said Suman Mahato, a resident.

Markets and schools remained closed and public transport also kept off the road following the shutdown.

People’s Committee against Police Atrocities (PCAPA), which is also demanding the withdrawal of troops from Lalgarh, supported the shutdown call.

Hundreds of Maoists, who seek to expand their influence in India, had declared the town of Lalgarh, about 170 kilometres from state capital Kolkata, as a ‘liberated zone’ before they fled in face of police action.

The Maoists were evicted from the trouble-torn Lalgarh region of West Medinipur district around June 20, only after an almost weeklong joint operation of the state armed police and federal elite security forces.

The villagers due to fear of Maoists have been demanding withdrawal of the security forces.

Officials apprehend such a demand is a ploy to give the Maoists a foothold again. (ANI)

CBI files 5000-page chargesheet against Padamsinh Patil

Mumbai, Aug 20(ANI): The Central Bureau of Investigation (CBI) on Thursday submitted a 5000-page chargesheet, in which it named suspended Nationalist Congress Party (NCP) MP Padamsinh Patil as the prime accused and conspirator in the 2006 murder of Congress leader Pawanraje Nimabalkar.

“The charge sheet, filed in a Panvel court, includes the statements of 181 witnesses and over 200 documents alleging the involvement of Patil and others in the crime,” said P Kandaswamy, the head of CBI’s Mumbai Zone.

In the chargesheet, the CBI alleged that Patil hatched the conspiracy to murder Nimbalkar due to political rivalry, as he nursed a suspicion that Nimabalkar had challenged his (Patil’s) survival in politics.

It also said that Patil had paid a ‘supari’ (contract killing) of Rs 30 lakh to the other accused to eliminate Nimbalkar.

The murder of Nimbalkar and his driver took place at a Navi Mumbai croosing on June 3, 2006.

The police had made no progress for two years until the city crime branch arrested jeweller Parasmal Jain in a robbery case. Jain disclosed the murder conspiracy and was handed over to the CBI. Patil was arrested on June 6 this year.

The other accused, who were charge sheeted are Jain, Satish Mandade, Mohan Shukla, Dinesh Tiwari, Kailash Yadav and Pintoo Singh. (ANI)

Natural organic matter plays key role in making mercury toxic to living creatures

Washington, August 19 (ANI): Scientists have found that naturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is toxic to most living creatures.

According to Duke University environmental engineers, this finding is important because it could change the way mercury in the environment is measured and therefore regulated.

This particularly harmful form of the element, known as methylmercury, is a potent toxin for nerve cells. When ingested by organisms, it is not excreted and builds up in tissues or organs.

In a series of laboratory experiments, Amrika Deonarine, a graduate student in civil and environmental engineering at Duke’s Pratt School of Engineering, found that organic matter and chemical compounds containing sulfur – known as sulfides – can readily bind to form mercury sulfide nanoparticles.

Since they are more soluble than larger particles, these nanoparticles may be the precursors to a process known as methylation.

“When the organic material combines with the mercury, it prevents the particle from accumulating with other mercury particles and growing larger,” said Deonarine.

“Since the mercury remains in a nanoparticle size, it can easily collect on the surface of microbes where any mercury that dissolves can be taken in by the microbes,” she said.

“Without the organic matter, the mercury sulfide nanoparticles would grow too large and become insoluble, thus reducing the availability of mercury for microbial methylation,” she added.

It is while inside the microbe that the mercury is converted into the harmful methylmercury form, according to the researchers.

These reactions can only take place in cold water environments with little to no oxygen, such as the zone of sediment just below the bottom of a body of water.

Other such anaerobic environments can also be found in waste water and sewage treatment systems, the researchers said.

Mercury is extremely toxic and can lead to kidney dysfunctions, neurological disorders and even death. In particular, fetuses exposed to methylmercury can suffer from these same disorders as well as impaired learning abilities.

There are many ways mercury gets into the environment, with the primary sources being the combustion of coal, the refining of such metals as gold and other non-ferrous metals, and in the gases released during volcanic eruptions. (ANI)

ISAF troops in Afghanistan need to get rid of their seige mentality

Kabul, Aug.13 (ANI): For the vast majority of troops at the International Security and Assistance Force (ISAF) headquarters, Afghanistan remains an enigma, a threatening land lying beyond the concertina wire of the base.

When ISAF troops venture out from their base into the “red zone” (i.e. the comparatively safe streets of Kabul) they are prepared for combat.

Barreling through the crowded streets of a city that has been called a comparative “safety zone” by those fighting in the south, they jam the phone signals of average Afghans with their ECMs (electronic counter measures) and jam the roads with their convoys.

Defeat takes the form of thousands of casualty-phobic troops ensconced behind the walls, sand bags, and blast barriers of a well-protected safety bubble.

One would think that the coalition vehicles driving around Kabul in combat posture and menacingly waving 50 caliber machine guns at Afghans were storming a Taliban sangar (trench) in Helmand, not competing with rush hour traffic.

The only Afghan most ever meet is the Hazara carpet seller on base who serves authentic Afghan food once a month. And the only coalition soldiers most Afghans meet are encased in armor-plated vehicles or flak jackets.

Only a small percentage of “fobbits” (those who live in forward operating bases or FOBs) actually interact with average Afghans due to hyper-protective S.O.P. (standard operating procedures) meant to lessen their risks from interaction with Afghans.

ISAF troops suffer from a siege mentality that led the United States dangerously close to losing the war in Iraq in 2005 and 2006. U.S. forces in Iraq were more concerned with force protection than protecting the center of gravity in Iraq, the Iraqi people.

It was only when Generals Petraeus and Odierno pushed their troops out of the bases and into the streets of Iraq that they began to make headway in the counterinsurgency.

This meant more meetings with Iraqi people, who began to feel that the Americans were protecting them.

For the most part, the coalition has ceded the countryside of the south and parts of the east to the enemy, who took advantage of the vacuum left by enemy troops in 2003 when the U.S. was focused elsewhere.

The White House’s fear of engaging in grassroots nation building allowed the Taliban to fill the void. Pro-government khans and mullahs were executed, villagers cowed into submission, and “vanguard” groups sent onto the next province to lay mines and kill “infidel collaborators.” With no visible coalition presence outside of the provincial capitals, the Taliban swarmed the countryside.

Much the same thing happened in Afghanistan in the 1980s under the Soviets, who controlled the major roads and cities and remained safe in their bases for fear of sustaining casualties.

The U.S. Marines’ recent efforts to clear and hold territory in Helmand Province represent a welcome break from this barracked mentality.

It is only by establishing a reliable coalition presence in contested places like Helmand that the coalition can show the Afghans that they are there to stay and protect them. (ANI)

Ground-to-air security ahead of Independence Day

New Delhi/Guwahati, Aug 13 (ANI): With India getting set to celebrate its 62nd Independence Day, the Central and Delhi State Governments have pulled out all steps to ensure that the event is santizied from a security point of view.

Following intelligence inputs that terror outfits have plans to target the Indian capital on August 15, over 60,000 officers of the Delhi Police, Special Cell, Crime Branch, Special Branch and around 35 paramilitary companies will be deployed in and around the city.

It is expected that around 6,000 police officers will be deployed near Red Fort.

Forty CCTV cameras have been installed in and around the Red Fort, while sharpshooters of the National Security Guard (NSG) will man buildings and rooftops near the historic monument.

Intelligence agencies have also reportedly identified ‘safety houses’ where the Prime Minister and other VIPs can be taken in the event of a terror strike.

Quick Reaction Teams, Special Weapons and Tactics (SWAT) and Vajra (of the Rapid Action Force) are also being deployed for the ocassion.

Informers have been deployed to look out for suspect anti-national elements, police sources said.

The entire area over Red Fort will be declared a no-fly zone during the function. Airspace would be closed from 6:00 a.m. to 10:00 a.m. and from 4:00 p.m. to 7:00 p.m.

Security has been tightened at the Parliament complex, IGI Airport, railway stations, inter-state bus terminals and Metro stations.

In other sensitive parts of the country like Jammu and Kashmir, and the northeastern states, security has been beefed up to counter possible terror or insurgent attacks.

In Guwahati, passengers are expected to be frisked at various checkpoints in the city.

Meanwhile, defying the boycott call, school students, NCC cadets and police personnel are busy preparing for the Independence Day parade.

“They are always giving calls to boycott Republic Day celebrations or Independence Day celebrations. But it is regularly celebrating Independence Day,” said Anna Rai,a school teacher.

The students are also upbeat about participating in the parade.

Security has also been beefed up along the India-Bangladesh border in Siliguri.

The Border Security Force (BSF) is on a high alert and keeping a strict vigil along the borders.

Home Ministry officials have warned that the Lashkar-e-Taiba plans to target three major cities, including Delhi on Independence Day.

Kolkata and Hyderabad are the other two LeT targets. (ANI)

Maoist violence on the decline in Jharkhand, say state police

Ranchi, Aug.9 (ANI): With security personnel carrying out an anti-Maoist drive for a month, a decline in the number of Maoist attacks in Jharkhand has been observed in comparison to the same period at this time last year.

“Maoist infested State of Jharkhand has seen a fall in number of attacks as compared to the last year. There has been a decline in Maoist violence in Jharkhand state,” a top police official said.

According to police statistics, there have been 228 Maoist attacks till end of July 2009, as compared to the 245 incidents recorded in 2008 in the same period.

Police say that as many as 20 most-wanted Maoists have been killed in 61 encounters besides 261 Maoists being arrested till July this year.

“The success against the banned Communist Party of India (Maoist) is a result of credible intelligence,” said S. N. Pradhan, Inspector General of Police in Jharkhand.

“We have got some big success owing to the intelligence information. The inputs provided to us were accurate about people and places. Action based on the intelligence helped us to get success against Maoists,” added Pradhan.

Police along with armed constabulary and paramilitary forces have launched operations to flush out the Maoists flush out from their bastions. They claim to have foiled many attacks of the ‘Red Army.’

“To be on the safer side, we deploy more security personnel in places which are more prone to Maoist attacks such as government offices, railways or main highways. At the same time, we deploy them in remote Maoist areas. This has helped us to understand the strategy Maoists follow in attacking and the kind of places they target. However, we are very careful as Maoists change their strategy frequently and we have to adapt accordingly,” said Pradhan.

Jharkhand is one of the worst affected of nine States facing more than three-decade-old Maoist revolt.

The Maoists have increasingly escalated to their rural eastern strongholds and are active in nearly a third of the country’s 630 districts, up from a presence in less than a tenth of them in 2001, government and independent data shows.

In June, Maoist rebels declared a “liberated zone” in West Bengal state, close to the city of Kolkata, sparking unease among investors in the communist-ruled state.

A large number of paramilitary forces are supporting the State police in the anti-Maoists driver in West Bengal’s Lalgarh area. (ANI)

Maoists torch an excavator machine in Bihar

Niyamatpur (Bihar), July 16 (ANI): Maoists set ablaze a JCB excavator, an earthmoving machine at Niyamatpur in Bihar’s Gaya District.

In the midnight hours of the intervening period of Tuesday and Wednesday, a group of Maoists raided a place near Niyamatpur and set ablaze a JCB excavator machine.

Police said that the rebels torched the excavator machine when they did not find anybody around.

“Nearly 10 men came. When they did not find anybody around, they set ablaze a JCB excavator machine. Fortunately, the engine of the machine is safe,” said Rajbansh Singh, Deputy Superintendent of Police.

Niyamatpur halt is located along the Patna-Gaya railway line and work is underway for doubling the tracks.

At least 36 policemen were ambushed by Maoists in Chhattisgarh on Sunday.

The Maoists have recently stepped up attacks against police, officials and civilians away from remote rural areas and closer to towns and cities across India.

Hundreds of Maoists, who are expanding their influence in India, had declared the town of Lalgarh about 170 km from Kolkata, as a “liberated zone” recently before they fled in face of police action.

Synchronised light bursts may make jet lag history

Washington, July 15 (ANI): A software program that prescribes a regimen for avoiding jet lag using timed light exposure has been created by researchers at Brigham and Women’s Hospital and the University of Michigan.

The method has been described in the open-access journal PLoS Computational Biology.

Traveling across several times zones can cause an individual to experience jet lag, which includes trouble sleeping at night and difficulty remaining awake during the day. These effects largely reflect de-synchronization between the body”s internal time clock and local environmental cues.

Now, the program, which seeks to re-synchronize the body with its new environment, considers inputs like background light level and the number of time zones traveled. Then, based on a mathematical model, the program gives users exact times of the day when they should apply countermeasures such as bright light to intervene and reduce the effects of jet lag.

Timed light exposure is a well known synchronization method, and when used properly, this intervention can reset an individual”s internal clock to align with local time. The result is more efficient sleep, a decrease in fatigue, and an increase in cognitive performance. Poorly timed light exposure can prolong the re-synchronization process.

Using their computational method, researchers simulated shifting sleep-wake schedules and the subsequent light interventions for realigning internal clocks with local time.

They found that the mathematical computation resulted in quicker design of schedules and also predictions of substantial performance improvements. They were able to show that the computation provided the optimal result for timing light exposure to reduce jet lag symptoms.

“Using this computation in a prototyped software application allows a user to set a background light level and the number of time zones traveled to obtain a recommendation of when to expose a subject to bright light, such as the bright lights sometimes used to treat Seasonal Affective Disorder” said lead-author Dennis Dean.

“Although this method is not yet available to the public, it has direct implications for designing schedules for jet lag, shift-work, and extreme environments, such as in space, undersea or in polar regions,” the expert added.

“This work shows how interventions can cut the number of days needed to adjust to a new time zone by half,” said co-author Daniel Forger. (ANI)

Ranchi police seize communication equipment meant for Maoists

Ranchi, July 15 (ANI): Ranchi police have recovered a consignment of communication equipment meant for Maoists.

The consignment was sent as cargo from New Delhi on a state-run domestic flight.

The recovered equipment included walkie-talkies, a number of radio sets, micro tape recorders and signal receivers, among others.

Police have detained three people and are interrogating them. They have also arrested one person from Palamu district. He will be brought to Ranchi later on Wednesday for further interrogation.

“They were unaware of what was in it. These three reached there to receive the consignment on behalf of Naresh Sharma. We arrested Naresh Sharma at Palamu,” said Praveen Kumar, senior superintendent of police, Ranchi.

New military robot to fuel itself by gobbling up dead bodies

Washington, July 15 (ANI): A Maryland company under contract to the Pentagon is working on a steam-powered robot that would fuel itself by gobbling up whatever organic material it can find – grass, wood, old furniture, or even dead bodies.

Robotic Technology Inc.’s Energetically Autonomous Tactical Robot (EATR) “can find, ingest, and extract energy from biomass in the environment (and other organically-based energy sources), as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil, and solar) when suitable,” reads the company’s Web site.

Animal and human corpses contain plenty of energy, and they’d be plentiful in a war zone.

EATR will be powered by the Waste Heat Engine developed by Cyclone Power Technology of Pompano Beach, Florida, which uses an “external combustion chamber” burning up fuel to heat up water in a closed loop, generating electricity.

The advantages to the military are that the robot would be extremely flexible in fuel sources and could roam on its own for months, even years, without having to be refueled or serviced.

Upon the EATR platform, the Pentagon could build all sorts of things – a transport, an ambulance, a communications center, even a mobile gunship.

Robotic Technology is presenting EATR as an essentially benign artificial creature that fills its belly through “foraging,” despite the obvious military purpose. (ANI)

Global warming may spell demise of key salt marsh constituent

Washington, July 14 (ANI): A new research has shown that global warming may exact a toll on salt marshes in New England, with one key constituent of marshes being especially endangered.

Pannes are waterlogged, low-oxygen zones of salt marshes.

According to Keryn Gedan, a graduate student and salt marsh expert at Brown University, despite the stresses associated with global warming, pannes are “plant diversity hotspots,”

“At least a dozen species of plants known as forbs inhabit these natural depressions,” Gedan said.

The species include the purple flower-tipped plants Limonium nashii (sea lavender), the edible plant Salicornia europaea (pickleweed) and Triglochin maritima, a popular food for Brent and Canada geese as well as ducks and other migratory waterfowl.

Gedan and her adviser, Mark Bertness, chair of the Ecology and Evolutionary Biology Department at Brown, decided to find out how global warming may affect pannes.

In a series of experiments, the pair subjected plots of forb pannes to air as much as 3.3 degrees Celsius (about 6 degrees Fahrenheit) warmer than the surrounding area.

They found that the plants in the test plots responded initially by growing more but then began a rapid die-off. As they died, they were replaced by a salt marsh grass, Spartina patens.

At two sites – Nag Creek (Prudence Island, Rhode Island), and Little River (Maine) – the forbs covered less than 10 percent of the plot, from 50 percent originally, in tests that spanned the summer from 2004 to 2006.

At the third site, Drakes Island (Maine), the forb pannes cover decreased from 50 percent of the plot to 44 percent (a 12-percent decline) in just the summer of 2007.

The researchers believe the forbs disappeared due to changes in the plant-water balance in the zone.

What that means, Gedan explained, is the warmer air causes the forbs to take in more water, thus making the area less waterlogged and more hospitable to an invasion by Spartina patens, which prefers less water-soaked conditions.

“The forbs basically engineer themselves out of their habitat by making it more favorable for their competitor,” said Gedan.

The Brown experiments “demonstrate that New England salt marsh pannes are extremely sensitive to temperature increases and will be driven to local and regional extinction with the temperature increases expected to occur in New England over the next century,” Bertness said. (ANI)
