How a T-Shirt Can Stop a Speeding Bullet

U.S. scientists have developed a flexible T-shirt made of the same material used in tank armor by combining carbon in the shirt fabric with the third-hardest material on the planet, boron. The seemingly normal plain white tee is dipped into a boron solution, and heated in an oven at more than 1000 degrees C, which changes the cotton fibers into carbon fibers.

Boron-treated T-shirt can stop speeding bullet, says scientist

  • Tee dipped in third-hardest material
  • Can capture bullet, says professor
  • Also blocks ultraviolet rays, radiation

THE humble T-shirt may soon be strong enough to stop a speeding bullet.

Scientists in the US have developed a flexible shirt made of the same material used in tank armor, by combining carbon in the shirt with the third-hardest material on Earth, boron.

"It could even be used to produce lightweight, fuel-efficient cars and aircrafts," Xiaodong Li, from the University of Southern Carolina, wrote in the journal Advanced Materials.

The plain white T-shirts are dipped into a boron solution, then heated in an oven at more than 1000C, which changes the cotton fibers into carbon fibers.

The carbon fibers react with the boron solution and produce boron carbide - the same material used to make bulletproof plates in armored vests.

The resulting material was stiffer than the original cotton tee, but still flexible enough to be worn as such.

"We expect that the nanowires can capture a bullet," Prof Li said.

But bullets are just the beginning for the new miracle material.

Prof Li said the T-shirts could also block "almost all" ultraviolet rays, and possibly life-threatening neutrons emitted from decaying radioactive material.

Assam Govt to Support Storm-Affected

storm Guwahati, Apr 15 : A day after a devastating thunderstorm killed four people and damaged up to 500 houses in Assam, the state government Thursday pledged all support to those affected.

“We have taken all possible measures to provide relief and other financial assistance to people hit by the storm. We have provided building materials to those whose houses were totally damaged,” Assam Relief and Rehabilitation Minister Bhumidhar Barman said.

Community groups and government agencies have also provided food and other essentials to those badly hit by the storm.

“We are doing our best in terms of providing urgent help to the affected families. The government should immediately announce substantial financial assistance to all those hit by the storm,” said Nurul Hussain, legislator from the Hajo area in Kamrup district of Assam.

“I have lost everything in just matter of minutes. We are ruined,” said Abhir Das, a farmer in Hajo area, 30 km off Assam’s main city of Guwahati.

Das’ mud and thatch hut was flattened while the storm damaged standing paddy crops and other vegetable cultivation.

The worst hit by the thunderstorm were Kamrup, Nalbari, Dhubri, and Nagaon districts of Assam with heavy rains accompanied by gushing wind and hailstorm lashing the region late Tuesday and again Wednesday.

There were similar reports of damage to properties and injuries from Nalbari and Nagaon districts.

Four people were killed in separate incidents of house collapse and trees falling on rooftops due to the cyclonic storm in Mancachar area in Dhubri district.

More than 12 people were injured and up to 50 homes damaged in the same area.

An estimated 300 houses were damaged in the Hajo area in Kamrup district.

The Meteorological Department predicted more rain and thunderstorms over most parts of Assam in the next 24 hours.

GSLV-D3 Launch Fails, Says ISRO

ISRO's GSLV-D3 launch fails

Sriharikota, Apr 15 : India's GSLV-D3 rocket, powered for the first time by an indigenous cryogenic engine, blasted off on time here on Thursday with a GSAT-4 satellite. But there was tension minutes later as the rocket stopped emitting signals.

After the rocket attained a height of 60 km, scientists at the control room here said they'd stopped getting signals.

Indian Space Research Organisation (ISRO) chairman K Radhakrishnan told reporters that the rocket began tumbling soon after launch "indicating the controllability was lost."

Two rocket engines failed to ignite, added an ISRO official.

So far only the US, Russia, European Space Agency, China and Japan have developed cryogenic engines. The successful launch of GSLV-D3 would have placed India in the elite league of masters of cryogenics, the science of very low temperatures.

The cryogenic engine gives higher thrust than conventional liquid and solid propellants to launch satellites weighing more than 4,000kg in geosynchronous orbit.

India had previously imported seven cryogenic engines from Russia, using five of them to launch heavy satellites over the last decade.

Tiger Density May Rise at Kaziranga

Jairam Ramesh New Delhi, Apr 15 : Environment Minister Jairam Ramesh today said preliminary reports from the second nationwide tiger census, currently underway, were very encouraging and that Kaziranga in Assam could show an increase in tiger density.

Evidence of the endangered Indian tiger had been found even in the Naxal-dominated reserve areas, which he said was the most “unexpected good news.” India has an estimated tiger population of 1,400.

A non-government organisation (NGO), Aranyak, had recently estimated the tiger density in Kaziranga at 32 tigers per 100 square kilometre. Corbett National Park in Uttarakhand and the Kanha tiger reserve in Madhya Pradesh were, so far, believed to be areas of highest tiger density. The estimated tiger density in Corbett is 20 tigers per 100 square km.

While briefing the media on a new software for collecting all field information on tigers, Ramesh said reports of tiger cub sightings and other marks of their presence had been received even from the Naxal-dominated reserve areas of Indravati in Chhattisgarh, Nagarjunasagar in Andhra Pradesh and Palamau in Jharkhand. In the buffer areas of Indravati, tiger faecal matter has been found.

The tiger census is expected to be completed by November.

However, the minister tempered this early enthusiasm by adding a cautious note that based on these observations, the ministry was not in a position to say what would be the final results. “Does it mean that the number of tigers is more than 1,400? I don’t know,” he added, bringing in a cautious note.

Data collection for Phase-I of the tiger census has been completed across the country, except in two states – Orissa and Arunachal Pradesh, the ministry said. Around 3.5 lakh square km of forest areas is being covered in this phase. Phase-II of this project, which involves data collection through satellite is also underway. In the third phase, the Wildlife Institute of India would use the collected data for camera trapping sessions.

The tiger population in India has been steadily going down. At the turn of the nineteenth century, some estimates suggest there were 45,000 tigers in India. The struggle to save the Indian tiger remains an uphill task as an international demand for tiger parts creates a lucrative trade and poaching of the endangered animal is hard to check . There is an enormous demand for tiger parts in several East Asian countries and especially China.

The ministry today launched a new software, M Stripes, which, he said, would be a valuable tool for forest directors to get field level information and track all surveillance.

Ramesh said the system will make it impossible to “doctor” any information and provide transparency. “We will have more reliable information on the extent to which patrolling is being done,” he said.

Unregulated tourism as bad as poaching: Ramesh

Environment minister Jairam Ramesh on Wednesday said unregulated tourism is as big a threat to tiger population as poaching and poisoning.
He objected to the way tourist lodges were constructed around the Corbett and other national parks. The issue had been discussed at the Wildlife Board and Prime Minister Manmohan Singh has written to the chief minister of Uttaranchal.
The chief minister, he said, has said that he would take action, “but the pressure on Corbett continues,” he added.
Ramesh said the ministry is in discussions with the state governments to take eco-tourism more seriously. Karnataka and Kerala were already doing this.

The system, which will also equip forest guards with GPS, will record field visits and capture detailed information on wildlife crimes such as poaching and poisoning of tigers. It is also expected to provide forecasting of poaching or habitat degradation, Y V Jhala, a scientist at Wildlife Institute of India, said.

The pilot project is proposed to be implemented within the next two months at six tiger reserves, which include Corbett, Kanha and Ranthambore.

Special efforts will also be made for a tiger census in the Sunderbans area, which is a difficult area to survey being a sea-based ecosystem.

Popular Radio Music Show Spreads Climate Change Message

Tribals sit with their children in Rngi, about 30 km (19 miles) south from Shillong, the capital of India's northeastern state of Meghalya, in January 2007. Families in remote areas of the state are now getting information about climate change via a popular FM radio music program.

By Teresa Rehman

Shillong, Apr 15 :  Climate change issues are reaching a remote new audience in Meghalaya, a hilly state in northeast India, via 'Mawsawa,' a popular FM radio music show.

'Mawsawa' in the local Khasi language, means a "tone that echoes back," a metaphor for imitation and spoof.

The pioneering show is "basically a spoof on Western music. For instance, a Bryan Adams song is sung in the local language but in the same tune, using traditional musical instruments. And the lyrics would be something to do with the environment and climate change," said Ian Khongmen, the head of 93.5 Red FM radio, the station that hosts the show.

The station, working in cooperation with the state government, is committed to raising awareness about the problems associated with climate change in the area, but is managing it with a new vigor, spiced with humor and drama, listeners say.

Better yet, the show is reaching even small remote villages that have yet to be electrified and do not yet have the luxury of television - places where a battery-powered radio may be the only way of receiving messages on climate change.

REACHING REMOTE AREAS WITH RADIO

"On my tours to remote hamlets, I have seen people listening to FM radio even on their mobile phones. I have seen farmers working and listening to radio. It was then that we decided to tie up with the FM station to spread the message of climate change and other environmental disasters at the grassroots level," said P.S. Nongbri, Meghalaya's deputy conservator of forests.

How effectively is the program reaching rural areas? Last year, when the forest department did a segment for World Wildlife Week in which they broadcast bird calls and asked listeners to identify the birds, "it was only people from interior villages who could answer correctly and win prizes. We were amazed by the reach of the radio," Nongbri said.

Talking about environment issues is an ongoing mission for the FM station. It has developed exclusive characters like Kong Lor (Kong is an endearing term for elder sister), who have become a vehicle for its messages.

"Kong Lor is like the conscience-keeper of the community who talks about the values and tradition which give us a sense of pride. She talks about environmental problems but with a lot of zest and spectacle and manages to strike the right emotional chord among the listeners," said Khongmen, the station head.

The radio station, on the air from 6 a.m. to 11 p.m., last year ran a series of segments aimed at generating awareness about the region's 'sacred groves' - protected forests that are tied up with local religious beliefs and are considered conservation models.

Another set of programs, for Earth Day, focused on the need for tree planting.

Disc jockeys regularly make their way to local festivals, and have helped put on street plays on environmental issues in association with local traditional institutions, or 'dorbars'.

"Our station is entertainment-based but we try to push in these pertinent issues," said R.J. Ashlyn, a presenter who runs a listener call-in evening show.

Meghalaya has witnessed large-scale deforestation due to illegal and poorly planned coal mining as well as pollution of its water resources by cement and limestone plants. Trees on Nongkhum island, the one of the biggest river islands in the West Khasi hills, are being indiscriminately felled to produce charcoal.

"Destruction of catchment areas of main rivers and streams caused by mining is the most pertinent problem in Meghalaya now," Nongbri said.

MUSICIANS JOIN INITIATIVE<

The radio initiative has caught on with local musicians with similar environmental interests. Kit Shangpliang, a musician from Shillong, the capital of Meghalaya, has been penning songs on themes including social evils, poverty and terrorism, and now has taken up climate change as well.

His rock band 'Summersalt' regularly focuses on conservation themes, be it conservation of forests or of indigenous culture and values. Songs use indigenous musical instruments of the Khasi people or even traditional kitchen tools turned into instruments.

"We want to look at conservation in a holistic manner. It's encouraging to see radio stations like Red FM talking about climate change," Shangpliang said.

The lyrics of one popular Khasi-language song go like this: "Have you given some thought to the destruction? Mother Earth is in shambles, the forests have been felled again and again. Have you thought how the creator would feel? Feel the pain, the sky has to endure." Radio hosts plan to feature the song in some of their programs.

"We are committed to create awareness about climate change," Khongmen said. "We are together in the fight to ensure a cleaner and more secure future for our planet."

Manipur Handloom Weavers Organize Buyer-Seller Meet

Imphal, Apr 15 : Manipur Apex Handloom Weavers & Handicraft Artisan CS Ltd. organized a one day buyer-seller meet cum exhibition housing 33 stalls. The event which was sponsored by the Government of India and Government of Manipur was inaugurated by Additional Chief Secretary, Govt of Manipur, Mr. PC Lawmkunga (IAS).

The stalls at the exhibition showcased variety of handlooms including, Churachandpur Handloom, Kakching Handloom, Wabagai Maibam Leikai Handloom, Khurai Thoudam Leikai & Ahongei Handloom, Uchathon Handloom, Dimdailong Handloom, Wangkhei Konsam Leikai Handloom, Moirang Kangjeibung Handloom and Kumbi Handloom Cluster.

The Government of India organizes a trade fair, every year, aiming to promote handloom products in domestic as well as in international markets. This trade fair, wherein around 45 handloom societies exhibit their products, witnesses’ visits of foreign as well as domestic visitors, informed Mr. Lawmkunga.

Improvement in quality and designs of the products is the key measure to attract the buyers towards the products. Manufacturing products, according to the consumers’ choice and requirement would accelerate the growth of handloom sector, he stated.

This sector is the second most important sector of the state, as weaving is the key source of income of most of the economically weak weavers, informed the Principal Secretary, Commerce & Industries, Mr. Nabakishore Singh.

In addition to this, old designs of handloom fabrics, which are still witnessing huge demand, need preservation. Besides, the measures such as motivation to the weavers and improvement of infrastructure should be taken on priority basis to enable the weavers to attain the product demands on time.

Crucial Meet on Naga Issue Next Week

Thuingaleng Muivah New Delhi, Apr 14 : A crucial meeting between militant outfit NSCN-IM and the government's interlocutor is likely to be held next week to give fresh impetus to the ongoing Naga peace process.

A delegation of NSCN-IM led by its general secretary Thuingaleng Muivah would hold parleys with new interlocutor R S Pandey to iron out differences on several vexed issues including integration of Naga-inhabited areas, official sources said.

The meeting will review the proposal given by the rebels to bring a lasting solution to the six-decade old Naga insurgency and the counter proposal given by the Central government.

NSCN-IM has proposed a federal relationship with the Indian Union with additional financial and legislative powers to handle while the Central government offered financial package for socio-cultural development of Naga people.

In the last round of talks in March, both sides resolved to their commitment to work out an honorable and negotiated solution to the problem. "There is seriousness on both sides to continue dialogue on sustained basis," a Home Ministry official said.

Among other issues in the charter demand, the NSCN-IM pointed out certain taxation matters and preservation of cultural heritage, the sources said. Muivah, who along with four other Naga leaders, arrived here on February 27 from Amsterdam. After the talks in March, he had gone to Nagaland and met NSCN-IM cadres, civil society members, NGOs and church leaders to discuss the issue. Pandey also undertook a visit to the north eastern states last week and met political leaders and other stake holders to get feedback from them.

A ceasefire was agreed on with NSCN-IM in August 1997. In May 1998, the union government had appointed Swaraj Kaushal as the first negotiator. He continued in his post till July 1999. After him, former Home Secretary K Padmanabhaiah took charge and continued till last year.

Pandey, a former Petroleum secretary and a 1972 batch Nagaland cadre IAS officer was appointed as a new interlocutor on February 11.

Burmese Music: Sound of The Underground

When the junta banned traditional protest songs, its leading exponents chose a life of exile rather than fall silent. Andrew Buncombe meets them in Delhi

Ngwe Toe sings in the Thangyat style

Ngwe Toe sings in the Thangyat style

First comes the sound of hand drums, followed by a voice that is steady and persistent. As Ngwe Toe leans back and angles his words towards the microphone, his lines are met by a chanting group which takes up his theme and sings back at him, as a call and response.

"The religion in our country," sings Toe, as the group answers for him, "is Theravada Buddhism". The activist continues: "The colour saffron is growing everywhere."

The group responds: "The monks are very graceful, but now their power has been drained. They are hiding in the remote areas."

As the drums continue in a dreamy loop, Toe implores: "Tell me why." The chanters tell him: "The military devil is rising up."

This is a traditional Burmese protest song with a modern twist. For generations, the people of Burma marked their new year by performing Thangyat – songs and skits that gave voice to local grievances.

In 1988, the year in which the military authorities violently crushed a series of democracy demonstrations with the death of at least 3,000 people, the junta decided it had endured enough protest and banned the tradition, threatening jail for anyone who dared to disobey.

But the generals could not stop Thangyat, merely drive it overseas. Now, communities of exiled Burmese around the world put together their own collections of protest songs, which are sold on CDs and even broadcast back into Burma where residents listen secretly on their radios.

One of the most famous and popular groups, of which Ngwe Toe is a member, is based in the west of Delhi. Ahead of the traditional four-day new year celebrations, or water festival, which begins today, the activists recorded and released a new collection of songs, music and poetry entitled Gaining Victory for Us and Defeat for Them.

"During the festival, it is a tradition that if there is something the people do not like, it will be criticised – be it politics, social affairs or food," said Zin Naing, who escaped to India from Burma after the 1988 uprising and who helped produce the recording.

"Now, inside Burma, Thangyat is not allowed, so ours has become one of the only ones that people can get. We produce it on CD as well as cassettes, which are smuggled into Burma."

There are an estimated 6,000 Burmese exiles in Delhi, most of them from Chin state, on India's north-eastern border. Many of them took part in the 1988 uprisings and came to India, which at the time was critical of the military authorities and welcomed the refugees. Most have never dared to even visit their home country since.

Ngwe Toe, the 40-year-old lead singer, fled when he was just 19, leaving behind all his relatives. His father died in 2003, but he dreams of returning to the country with his wife and young son, and of being able to show his child to his mother.

In the meantime, he takes some measure of comfort from imagining his family furtively listening to the songs of protest that he and his friends have recorded. "It's like a rap," he said. "I say the first line and then the others respond with the second. It's a call and response, and when I am singing, I am shouting these slogans with emotion. I am very focused on the song. I would be happy if my mother hears it, and would then be able to give the message that her son is involved in the politics."

The lyrics for the song performed by Ngwe Toe were written by a Buddhist monk, forced to escape to India after taking part in the so-called Saffron Revolution of September 2007, when tens of thousands of monks and citizens took to the streets of Rangoon and other major cities, demanding democratic reforms.

The monk, U Dhamma, a smiling, round-faced 23-year-old, fled after he and several other monks from his monastery joined the demonstrations in the northern city of Mandalay. "I took part in the marches. I thought there would be a revolution. I believed in democratic rule for Burma," said the monk, who crossed into north-eastern India in January 2008 and now lives in the same dusty Delhi neighbourhood as many other exiles. "After the marches, I stayed at the monastery for some months, but then a minister came to give food. We were very angry and refused to accept this. The minister put pressure on the abbot to expel us, and the next day our names were put in the newspaper, saying that we were to be expelled. We had no chance to stay in Burma."

Those who wrote the collection of protest songs have had no shortage of material to inspire them over the past 12 months. Last year, the junta extended the house arrest of opposition leader Aung San Suu Kyi for 18 months, after she was convicted of breaching the terms of her detention when an uninvited US tourist swam to her lakeside home.

Then, last month, the regime announced new rules governing the controversial election due to be held later this year. The rules effectively bar Ms Suu Kyi from standing and say that her party, the National League for Democracy, (NLD), would have to oust her if it wished to field candidates. The NLD has announced it is boycotting the election.

It is not just the junta that comes in for criticism in the Thangyat. While the songs indeed condemn the regime's alleged nuclear ambitions, the election and the country's poverty, the NLD and even politicians in exile are also subjects of satire.

Such humour has long been a tradition of subtle dissent in Burma. One of the country's best-known comics, Zarganar, spent many years making barbed puns about the regime. Eventually, in 2008, the junta ran out of patience with him and seized on an interview he had given to the BBC criticising the authorities' response of the aftermath of Cyclone Nargis. He was jailed for 59 years, a sentence reduced to 35 on appeal.

Likewise, in Mandalay, members of a famous comic troupe known as the Moustache Brothers have been in and out of jail as a result of their performances making fun of the junta.

The Burmese exiles who put together the protest album remain confident that change can come. The song performed by Ngwe Toe says the monks will lead the transformation.

Its last lines, sung as call-and-response, conclude: "If the monks unite – the military becomes afraid. If the monks unite – the religion will be glowing. If the monks take to the front lines – we will escape from poverty. If the monks speak the truth – they will speak to the whole world."
