UPDATE 1-Low & Bonar profit rises; keeps upbeat FY view

July 13 (Reuters) – British specialist materials group Low & Bonar Plc (LWB.L) posted a 31 percent rise in adjusted first-half pretax profit, helped by growth in transport and leisure sectors, and kept an upbeat full-year trading outlook.

The company, which supplies yarn, fabric and fibre to end-markets like civil engineering, transport, sport and leisure, said it would pay an interim dividend of 0.5 pence.

“The much improved sales pattern established throughout the second quarter, has continued into the start of the second half,” Chief Executive Steve Good said in a statement.

In June, the company had forecast full-year trading ahead of its own expectations.

Analysts on average expect Low & Bonar to post a full-year pretax profit of 18 million pounds ($27.1 million) on revenue of 329.4 million pounds, according to Thomson Reuters I/B/E/S.

For the six months to end-May, the company reported a pretax profit of 6.7 million pounds before amortisation and one-time items, compared with 5.1 million pounds a year ago.

Revenue rose 11.7 percent to 155.8 million pounds.

Low & Bonar lowered its net debt by almost 32 percent to 67.4 million pounds at the end of the period.

Shares of the company closed at 43 pence on Monday on the London Stock Exchange. ($1=.6655 Pound) (Reporting by Aditi Samajpati in Bangalore; Editing by Roshni Menon)

Women prefer chocolate to sex, wine!

London, Apr 24 (ANI): A third of women dream about chocolate during the day, compared with only 18 per cent who think about sex, says a new British survey.

Around 2.3 million British women admitted that they have the sweet treat at least three times a day, reports The Daily Express.

On the other hand, six in 10 men have sex on their minds for most of the day and 11 per cent think about chocolate, the study found.

According to the study of 2,000 women, which was carried out by cereal bar firm Fibre Plus, more than one in five women say they would kiss goodbye to their sex lives before chocolate.

What’s more, a quarter would rather give up chardonnay and Chanel.

Spokeswoman Sally Tribe said: “Women turn to chocolate for comfort, or to cheer themselves up.

“For many, it never disappoints.” (ANI)

Chipmill defends biomass power plans

A New South Wales South East woodchip provider has refuted criticism by a State Greens MP about its proposed biomass power plant.

South East Fibre Exports plans to use chipmill timber waste from its Eden operations to generate electricity in a 5.5 megawatt plant.

Greens MP John Kaye says the project lacks environmental and economic credibility, and is not an acceptable method of renewable energy.

But chipmill spokesman Vince Phillips says biomass power is endorsed world-wide.

“I think you can look just about anywhere in the world, and renewable energy from biomass power is accepted as one of the mainstream responses to producing base-load electricity from renewable sources,” he said.

“That is happening right through Europe, North America, everywhere you would like to name.

“He is really saying that in South East New South Wales we have got to be different. We are not different.”

He says Mr Kaye has become a source of chronic misinformation in state parliament.

‘Green light’ for power generator

A New South Wales Far South Coast chip mill says an environmental assessment has given its proposed wood waste power generator project a green light.

South East Fibre Exports plans to use timber waste from its Eden operations to generate electricity in a 5.5 megawatt plant.

The proposal has concerned conservationists who want to stop native forest logging.

Chip mill spokesman, Vince Phillips says the generator will not breach environmental regulations, but he says anyone can make a submission on the application when it goes on display today.

“I guess you will see a range of submissions from people who support the process through to people who do not support the process,” he said.

“Some of the submissions will be based on good information and some will be based on total mis-information.”

The assessment is on display at the Bega Valley Shire council building, the Eden Library, and is available on the state planning department website.

The deadline for public submissions is April 22.

Emma Watson used gap year to design teen summer wear for People Tree

London, Sep 18 (ANI): Harry Potter star Emma Watson has revealed that she spent her gap year designing a ‘complete teenage summer wardrobe’ for the fair trade fashion brand People Tree.

Watson, 19, who has just enrolled at Brown University in the US, acted as a creative advisor for the ethical fashion collection, which will reach shops in February.

“I wanted to help People Tree produce a younger range because I was excited by the idea of using fashion as a tool to help alleviate poverty and knew it was something I could help make a difference with,” Sky News quoted her as saying.

“I think young people like me are becoming increasingly aware of the humanitarian and environmental issues surrounding fast fashion and want to make good choices but there aren’t many options out there.

“It has been the most incredible gap year project,” she added.

Among items that the teen actress has had a hand in designing were knitwear, cotton t-shirts, jersey dresses, and poplin shorts.

Her range also includes some more bizarre items, including “bohemian hand embroidered bed throws, recycled sweetie wrapper jewellery, banana fibre slouchy beanies and head scarves.”

They will be sold by People Tree, a company which aims at supporting developing countries and promoting environmental projects. (ANI)

Silk made by common Australian green lacewing toughest: Study

Melbourne, September 10 (ANI): A new research has found that Australian lacewings build tougher silk than silkworms.

Scientists at CSIRO Entomology have learnt that silk made by the common Australian green lacewing can be stretched up to six times further than silkworm silk.

Moreover, its unusual structure makes it potentially much easier to manufacture artificially.

The common Australian green lacewing (Mallada signata) produces silk to create tiny stiff stalks to hold each of its eggs on.

The insect pushes out a liquid drop of silk dope before stretching it out to the point at which it stiffens and then placing the egg safely on top.

Researchers found that the lacewing silk was different from the silk created by other insects and had had its own evolutionary pathway.

Unlike the plank-like structure of other silks from spiders or silkworms, lacewing silk contains two fibrous proteins structured like a concertina door, giving it extra toughness and elasticity.

According to Dr Tara Sutherland, who was part research team, the lacewing silk protein is also shorter and less repetitive, making it easier to reproduce artificially by fermentation in bacteria.

“Silks are made under benign conditions. They’re made at room temperature, from an aqueous system and from readily replaced building blocks, so it’s a very environmentally friendly process, in contrast to the synthetic equivalents,” ABC Science quoted Sutherland as saying.

She added: “The material has a lot of strength and it’s very, very light so it’s quite remarkable. It’s also very tough.”

Apart from the traditional textile uses, the biocompatibility of the natural fibre allows this kind of silk to be used in high-tech medical applications such as providing the scaffolding for growing new human cells on.

The research will be published in the Journal of Structural Biology. (ANI)

Soluble fibre ‘effective in treating irritable bowel syndrome’

London, Aug 28 (ANI): A new study by researchers from Utrecht University in the Netherlands has suggested that a soluble fibre supplement called psyllium should be the first line of attack in treating irritable bowel syndrome (IBS).

In the study, researchers compared adding bran, psyllium and a dummy supplement to sufferers’ diets.

They found psyllium was the most effective, warning that bran may even worsen the symptoms of the condition.

IBS is characterized by abdominal pain and an irregular bowel habit.

Its exact cause is unknown and recommendations for treatment include dietary advice, antidepressants and drug treatments.

Many relying on dietary adjustments still turn to bran in a bid to help improve the way the intestines work.

However, the new study of 275 patients questions the wisdom of this approach.

The researchers gave patients 10g of either psyllium, bran or rice flour twice a day for 12 weeks.

At the end of the study, those on psyllium, a naturally occurring vegetable fibre, reported symptom severity had been reduced by 90 points using a standard scale of rating problems.

For bran it was 58 points and for the placebo group, 49.

The study also showed that patients seemed less tolerant of bran, with more than half of the group dropping out during the trial, mostly because their symptoms worsened.

Soluble fibre can also be found in fruit such as apples and strawberries, as well as barley and oats.

“I think adding psyllium to the diet is the best treatment option to start with. In the study, people did this by adding it to things such as yoghurt and it had a real effect,” the BBC quoted Dr Niek de Wit, one of the researchers, as saying.

The study has been described in the British Medical Journal. (ANI)

Swine flu as Ganesh Chaturthi’s theme in Pune

Pune, Aug 21 (ANI): Organisers of the hugely popular Ganesh Chaturthi festival in Pune take up swine flu as festival theme to spread awareness among the people.

The highlights of the festival are fibre mannequins wearing swine flu masks erected by talented artists in the Pune

These special mannequins will have audio-visual support to convey the message regarding swine flu precautions. Some of them are portrayed as school going kids, teachers, doctors all are shown wearing masks.

“During this 10-day Ganesh festival, we have started an awareness programme about swine flu. The aim is to aware people about the flu. Also, there will be allopathic, homeopathic and ayurvedic doctors in the festival, who will provide medication to those who need,” said Srikant Shete, President of Kasba Sarwajanik Ganesh Mandal, Pune.

Another motive is to remind people to take precautions and avoid swine flu infection during the celebration.

India recorded its first H1N1 case in Hyderabad in May and since then the virus has spread across the country with dozens of cases from western Pune city. The latest death toll in India is 33. (ANI)

Tone-deaf people lack an important neural pathway

Washington, Aug 19 (ANI): Researchers have found that the nerve fibres that link perception and motor regions of the brain are disconnected in tone-deaf people.

According to experts’ estimates, at least 10 percent of the population may be tone deaf – unable to sing in tune.

The new finding has pinpointed a particular brain circuit that is believed to be absent in these individuals.

“The anomaly suggests that tone-deafness may be a previously undetected neurological syndrome similar to other speech and language disorders, in which connections between perceptual and motor regions are impaired,” said Dr. Psyche Loui, of Beth Israel Deaconess Medical Center and Harvard Medical School, one of the study’s authors.

For the study, the researchers used an MRI-based technique called diffusion tensor imaging to examine connections between the right temporal and frontal lobes.

It is known that this region, a neural “highway” called the arcuate fasciculus, is involved in linking music and language perception with vocal production.

They took brain images of 20 people, half of whom had been identified as tone-deaf through listening tests.

The arcuate fasciculus was smaller in volume, and had a lower fibre count in the tone-deaf individuals.

Particularly, the superior branch of the arcuate fasciculus in the right hemisphere could not be detected in the tone-deaf individuals.

Thus, the researchers speculated that this could mean the branch is missing entirely, or is so abnormally deformed that it appears invisible to even the most advanced neuroimaging methods.

“The findings are clear. They show that the arcuate fasciculus, a structure long-known to join perceptual and motor areas, has reduced connectivity in individuals with tone deafness. Beyond improving our understanding of the anatomical underpinnings of tone-deafness, this study provides new insight into a person’s ability to detect pitch,” said Dr. Nina Kraus, at Northwestern University.

The findings add to previous work by the same researchers demonstrating that tone-deaf people could not consciously hear their own singing, and work by other researchers indicating abnormalities in brain regions that affect sound perception and production.

The study has been published in the latest issue of The Journal of Neuroscience. (ANI)

Scientists unveil new way to clinically assess condition of tooth enamel using lasers

Washington, August 19 (ANI): A collaborative study conducted by Australian and Taiwani researchers has led to a novel way to analyse the health of human teeth using lasers.

Described in the open-access journal Optics Express, the new approach involves measuring how the surface of a tooth responds to laser-generated ultrasound, which can help evaluate the mineral content of tooth enamel-the semi-translucent outer layer of a tooth that protects the underlying dentin.

This is the first time that any research team has been able to non-destructively measure the elasticity of human teeth, creating a method that can be used to assess oral health and predict emerging dental problems, such as tooth decay and cavities.

“The ultimate goal is to come up with a quick, efficient, cost-effective, and non-destructive way to evaluate the mineralization of human dental enamel,” says David Hsiao-Chuan Wang, a graduate student at the University of Sydney in Australia and first author on the paper.

For research purposes, “nano-indentation” is commonly used for gaining information on the elasticity of tooth enamel-a measure of its mineral content. However, nano-indentation destroys the measured regions of the enamel in the process and is only used to look at extracted teeth.

Wang and his advisor Simon Fleming, a physics professor at the University of Sydney’s Institute of Photonics and Optical Science, said that they wanted to develop a clinical method that would give as much information as nano-indentation and could be used to assess tooth enamel in actual patients while being completely non-destructive.

So, added the researchers, they developed a way to measure the elasticity of tooth enamel by adapting laser ultrasonic surface wave velocity dispersion, a method similar to what industrial engineers use to evaluate the integrity of thin films and metals.

They have revealed that their approach uses short duration laser pulses to excite ultrasonic waves that propagate along the surface, and penetrate only a small distance into a tooth.

The velocity of these waves is influenced by the elastic properties of the enamel on a tooth, and by detecting the ultrasonic waves with fibre optics at various points, they can determine the enamel’s elasticity, which is directly related to its mineralisation.

In their research article, the researchers have written that they could use this technique on extracted human teeth.

They admit that they have not yet tested the technique on a living person’s teeth, and that it will likely take several years before any eventual device is ready for use in the dentist’s office. (ANI)

Scientists build largest ever quantum key distribution network

Washington, July 2 (ANI): Researchers from across Europe have united to build the largest quantum key distribution (QKD) network ever built.

The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.

With an average link length of 20 to 30 kilometres, and the longest link being 83 kilometres, the researchers from organisations such as the AIT Austrian Institute of Technology, Toshiba Research in the UK, Siemens, and many more have broken all previous records and taken another huge stride towards practical implementation of secure, quantum-encrypted communication networks.

Undertaken in late 2008, using the company internal glass fibre ring of Siemens and 4 of its dependencies across Vienna plus a repeater station, near St. Polten in Lower Austria, the QKD demonstration involved secure telephone communication and video-conference as well as a rerouting experiment which demonstrated the functionality of the SEcure COmmunication network based on Quantum Cryptography (SECOQC).

One of the first practical applications to emerge from advances in the sometimes baffling study of quantum mechanics, quantum cryptography has become a soon-to-be reached benchmark in secure communications.

Quantum mechanics describes the fundamental nature of matter at the atomic level and offers very intriguing, often counter-intuitive, explanations to help us understand the building blocks that construct the world around us.

Quantum cryptography uses the quantum mechanical behaviour of photons, the fundamental particles of light, to enable highly secure transmission of data beyond that achievable by classical methods.

The photons themselves are used to distribute cryptographic key to access encrypted information, such as a highly sensitive transaction file that, say, a bank wishes to keep completely confidential, which can be sent along practical communication lines, made of fibre optics.

Quantum indeterminacy, the quantum mechanics dictum which states that measuring an unknown quantum state will change it, means that the information cannot be accessed by a third party without corrupting it beyond recovery and therefore making the act of hacking futile.

According to the researchers, “In our paper we have put forward, for the first time, a systematic design that allows unrestricted scalability and interoperability of QKD technologies.” (ANI)

Soon, bulletproof vests made of cement

Washington, June 30(ANI): A new type of body armour made from cement is being developed by engineers at the University of Leeds.

The boffins are combining super-strong cement with recycled carbon fibre materials to make a material tough enough to withstand most types of bullets.

Dr Philip Purnell, who is leading the team at the School of Civil Engineering in the University, said: “By using cement instead of alumina we are confident we can deliver a cost-effective level of protection for many people at risk. It should be good enough for people like security guards, reporters and aid workers who are worried about the odd pot shot being taken at them.

“The fact is many of the armoured vests sold today are over-engineered for the threats they face. Cement based body armour would not only create a whole new market but it would also take some of the pressure off the demand for hi-spec alumina models so that people like soldiers, who really need this kit, can get it.”

Till date, hi-spec body armour is constructed with alumina plates the raw material used to make aluminium – which is heated to 1600 degrees Celsius for up to two weeks in a process called ‘sintering’ making them ultra hard.

Enhanced combat body armour (ECBA) as supplied to UK troops uses sintered alumina plates.

However, in the past UK and US soldiers serving in Iraq and Afghanistan have faced shortages of ECBA as production has struggled to keep up with soaring global demand.

Leeds engineers call the project ‘Cementing the future’ and also suggest putting the material to use in pump-less fridges, a new type of catalytic converter, and improved bone replacements. (ANI)

Massive fire engulfs optical fibre cable factory in UP

Allahabad, May 10 (ANI): A massive fire engulfed an optical fibre cable factory in Naini area of Allahabad in Uttar Pradesh on Sunday.

The fire broke out at 7.30 a.m. in the Hindustan Cable Limited factory and soon spread causing panic amongst the people.

Around seven fire engines were called in to control the raging fire.

“Fire broke out at around 7.30 in the morning at the Hindustan Cable factory. Fire engines are deployed in dousing the fire,” said Ram Avataar Verma, stationfficer, Naini.

Scrap optical fibre worth thousands of rupees was destroyed in the fire. The cause of the fire is still not known.
Last year also, a similar fire broke out at Hindustan Cable factory.(ANI)

How scientists made fast quantum communication possible

Washington, April 30 (ANI): Researchers from Toshiba and Cambridge University’s Cavendish Laboratory have developed high speed detectors that are capable of receiving information with much higher key rates, thereby able to receive more information faster, in a technique known as quantum cryptography.

Carried in the journal paper, ‘Practical gigahertz quantum key distribution based on avalanche photodiodes’, the research details how quantum communication can be made possible without having to use cryogenic cooling and/or complicated optical setups, making it much more likely to become commercially viable soon.

One of the first practical applications to emerge from advances in the often baffling study of quantum mechanics, quantum cryptography has become the soon-to-be-reached gold standard in secure communications.

Quantum mechanics describes the fundamental nature of matter at the atomic level and offers very intriguing, often counter-intuitive, explanations to help us understand the building blocks that construct the world around us.

Quantum cryptography uses the quantum mechanical behaviour of photons, the fundamental particles of light, to enable highly secure transmission of data beyond that achievable by classical encryption.

The photons themselves are used to distribute keys that enable access to encrypted information, such as a confidential video file that, say, a bank wishes to keep completely confidential, which can be sent along practical communication lines, made of fibre optics.

Quantum indeterminacy, the quantum mechanics dictum which states that measuring an unknown quantum state will change it, means that the key information cannot be accessed by a third party without corrupting it beyond recovery and therefore making the act of hacking futile.

While other detectors can offer a key rate close to that reported in this journal paper, the present advance only relies on practical components for high speed photon detection, which has previously required either cryogenic cooling or highly technical optical setups, to make quantum key distribution much more user-friendly.

Using an attenuated (weakened) laser as a light source and a compact detector (semiconductor avalanche photodiodes), the researchers have introduced a decoy protocol for guarding against intruder attacks that would confuse with erroneous information all but the sophisticated, compact detector developed by the researchers.

According to the researchers, “With the present advances, we believe quantum key distribution is now practical for realizing high band-width information-theoretically secure communication.” (ANI)

Laser light can help treat brain-related disorders

London, Apr 27 (ANI): In a first of its kind study, researchers at Massachusetts Institute of Technology have found a way to induce gamma waves by shining laser light directly onto the brains of mice, which could lead to new treatments of brain-related disorders.

For a long time, scientists have studied high-frequency brain waves, known as gamma oscillations, believing them to be crucial to consciousness, attention, learning and memory.

But, in the new study, researchers used a newly developed technology known as optogenetics, which combines genetic engineering with light to manipulate the activity of individual nerve cells.

The study could explain how the brain produces gamma waves and provides new evidence of the role they play in regulating brain functions, which could someday lead to new treatments for a range of brain-related disorders.

“Gamma waves are known to be [disrupted] in people with schizophrenia and other psychiatric and neurological diseases. This new tool will give us a great chance to probe the function of these circuits,” Nature quoted Li-Huei Tsai, Picower Professor of Neuroscience and a Howard Hughes Medical Institute investigator, as saying.

Gamma oscillations reflect the synchronous activity of large interconnected networks of neurons, firing together at frequencies ranging from 20 to 80 cycles per second.

“These oscillations are thought to be controlled by a specific class of inhibitory cells known as fast-spiking interneurons. But until now, a direct test of this idea was not possible,” says Jessica Cardin, co-lead author on the study.

For finding out which neurons drive the oscillations, the researchers used a protein called channelrhodopsin-2 (ChR2), which can sensitise neurons to light.

“By combining several genetic tricks, we were able to express ChR2 in different classes of neurons, allowing us to manipulate their activity with precise timing via a laser and an optical fibre over the brain,” explains co-lead author Marie Carlen.

The trick for inducing gamma waves was the selective activation of the “fast-spiking” interneurons, named for their characteristic pattern of electrical activity.

When these cells were driven with high frequency laser pulses, the illuminated region of cortex started to produce gamma oscillations.

“We’ve shown for the first time that it is possible to induce a specific brain state by activating a specific cell type” said co-author Christopher Moore.

On the other hand, no gamma oscillations were induced when the fast-spiking interneurons were activated at low frequencies, or when a different class of neurons was activated.

Also, the researchers showed that these brain rhythms regulate the processing of sensory signals.

They found that the brain’s response to a tactile stimulus was greater or smaller depending on exactly where the stimulus occurred within the oscillation cycle.

“It supports the idea that these synchronous oscillations are important for controlling how we perceive stimuli. Gamma rhythms might serve to make a sound louder, or a visual input brighter, all based on how these patterns regulate brain circuits,” said Moore.

The study was published in the latest online issue of Nature. (ANI)

Research and Markets: Fast Track: Gas Plasma Treatments for Water Repellent Technology

DUBLIN–(Business Wire)–
Research and Markets
(http://www.researchandmarkets.com/research/b2f944/fast_track_gas_pl) has
announced the addition of Textiles Intelligence’s new report “Fast Track: Gas
Plasma Treatments for Water Repellent Technology” to their offering.

Gas plasma technology can be used to change the surface properties of certain
types of materials, including ceramics, fabrics, leather, metals, paper and
polymers.

The technology involves the exposure of the material to a plasma at low
pressure, usually in a purpose built chamber. A plasma is a partially ionised
gas in which a certain proportion of negatively charged electrons are able to
flow freely rather than being bound to an atom or molecule. This makes the
plasma electrically conductive and highly responsive to electromagnetic fields.

Recently, gas plasma technology has been successfully applied to performance
footwear as an alternative to water repellent coatings.

The technology offers a number of benefits compared with traditional chemical
treatments. In particular, the treatment is said to be more thorough as it
covers the surface of every fibre and the voids in between the fibres.

Scientists unveil novel approach to study Parkinson’s treatment

Washington, April 17 (ANI): Stanford University researchers claim that they have identified a specific group of cells that can be direct targets of deep brain stimulation (DBS), a Parkinson’s treatment.

Lead researcher Karl Deisseroth attributes this advance to a technique to systematically characterize disease circuits in the brain.

The researcher says that the NSF-funded technology, termed optogenetics, enabled them to precisely control individual components of the circuit implicated in Parkinson’s disease.

The novel technology uses light-activated proteins, originally isolated from bacteria, in combination with genetic approaches to control specific parts of the brain.

It is a vast improvement over previous methods because it allows researchers to precisely stimulate neurons, and measure the effect of treatment simultaneously in animals with Parkinson’s-like symptoms.

Deisseroth’s team found that they could reduce disease symptoms by preferentially activating neurons that link to the subthalamic nucleus region of the brain.

The researchers first treated these specific cells in a way that made them sensitive to stimulation by blue light, and then implanted an optical fibre in the brain.

When researchers rapidly flashed blue light inside the animals’ brains the disease symptoms improved.

They said that treating with slower flashes of light actually made the symptoms worse, and targeting other kinds of cells had no effect at all, indicating both proper cell type and stimulation frequency are crucial components of effective treatment.

According to the research team, flashing blue light on portions of the same neurons found closer to the outer surface of the brain had an effect similar to treatment deep within the brain, raising the possibility that researchers may be able to develop treatments that are less invasive than current options.

Deisseroth said: “The brain is an electrical device, but it is a very complicated device. Think of it as an orchestra without sections: all of the types of instruments, or cells, are mixed together. Treatments like DBS are unrefined, in that they stimulate all of the cells or instruments. The optogenetic approach allows us to control stimulation of specific cells in the brain on the appropriate timescale, much like a conductor directing specific sections of an orchestra at the appropriate time.”

He added: “We need to understand the players before we can develop effective treatment strategies.”

Why touching the skin relieves pain

London, April 15 (ANI): Scientists at the Sahlgrenska Academy have found out why touching the skin relieves pain.

The researchers have revealed that the skin has specialised nerve fibres called called CT nerves (C-tactile), which travel directly to the areas in the brain that are important in the emergence of feelings.

“Basically, the signals that tell the brain that we are being stroked on the skin have their own direct route to the brain, and are not blocked even if the brain is receiving pain impulses from the same area. In fact it’s more the opposite, that the stroking impulses are able to deaden the pain impulses,” Nature magazine quoted Line Loken, postgraduate student in neurophysiology at the Sahlgrenska Academy, as saying.

The researchers used a technique called microneurography to examine a group of healthy subjects.

“By inserting a thin electrode into a nerve in the forearm we can listen in on the nerve and pick up signals from one of the thousands of nerve fibres that make up a nerve,” explains Associate Professor Hakan Olausson, who is leading the research group behind the discovery, together with Johan Wessberg.

According to the research team, each individual nerve fibre was responsible for touch signals from roughly a square centimetre of skin.

During the study, the researchers used a specially-designed robot that brushed over the exact area of skin for which a particular nerve fibre is responsible.

They also asked the participants to rate how pleasant or unpleasant they found the brushing.

“As the nerve signals that were sent in the CT nerves became more frequent, the subjects reported the experience as being increasingly pleasant. Of the skin nerves that we studied, it was only the CT nerves that had this strong link between the frequency of the signals and how pleasant it felt,” says researcher Johan Wessberg.

The study has been published in the journal Nature Neuroscience. (ANI)

Vegetable- and nut-intake and Mediterranean diet linked to lower heart disease risk

Washington, April 14 (ANI): Vegetable and nut intake and a Mediterranean dietary pattern seem to lower the risk of heart disease, according to a review of past studies.

However, the review also suggests that the consumption of trans-fatty acids and foods with a high glycemic index may be harmful to heart health.

Dr. Andrew Mente and his colleagues at the Population Health Research Institute carried out a systematic search for articles investigating dietary factors in relation to heart disease, published between 1950 and June 2007.

The researchers identified 146 prospective cohort studies that looked back on the habits of a particular group of individuals, and 43 randomised controlled trials wherein participants were randomly assigned to a dietary intervention or a control group.

They said that upon pooling the study results and applying a predefined algorithm, “we identified strong evidence of a causal elationship for protective factors, including intake of vegetables, nuts and monounsaturated fatty acids and editerranean, prudent and high-quality dietary patterns, and harmful factors, including intake of trans-fatty acids and foods with a high glycemic index or load and a western dietary pattern.”

They write: “Among these dietary exposures, however, only a Mediterranean dietary pattern has been studied in randomised controlled trials and significantly associated with coronary heart disease.”

The research team also found modest relationships supporting a causal relationship between intake of several other foods and vitamins and heart disease risk, including fish, omega-3 fatty acids from marine sources, folate, whole grains, alcohol, fruits, fibre and dietary vitamins E and C and beta carotene.

The study also supported causal relationships between vitamin E and ascorbic acid supplements, saturated and polyunsaturated fatty acids and total fats, alpha-linoleic acid, meat, eggs and milk.

“The modest or weak evidence of these dietary exposures is mostly consistent with the findings of randomised controlled trials, although randomised controlled trials have yet to be conducted for several factors,” the authors write.

“Taken together, these findings support a causal relationship between only a few dietary exposures and coronary heart disease, whereas the evidence for most individual nutrients or foods is too modest to be conclusive.

“Although investigations of dietary components may help to shed light on mechanisms behind the benefits of dietary patterns, it is unlikely that modifying the intake of a few nutrients or foods would substantially influence coronary outcomes,” they conclude. “Our findings support the strategy of investigating dietary patterns in cohort studies and randomized controlled trials for common and complex chronic diseases such as coronary heart disease,” they add.

The study has been published in the Archives of Internal Medicine, one of the JAMA/Archives journals. (ANI)

Environmental concern helps West Bengal’s jute industry thrive

Kolkata, April 9 (ANI): World environmental concerns have come as a bonus for the ailing jute industry in West Bengal.

The eco-friendly ‘golden fibre’ is finally finding its place in the limelight with the growing popularity of diversified jute goods.

Earlier, jute was just associated with the ugly sacks used for packaging, mainly in the sugar and cement industries. But with diversification into designer bags, wall-hangings, jute paintings, shoes, textiles even jewelry now, jute is rapidly emerging as a reusable alternative for the environment conscious citizens.

With several states banning use of polythene bags as a measure to protect the environment, jute has got a new lease of life in the carrier segment alone in the form of clutch bags, party bags, laundry bags, rucksacks, gunny bags, totes, shopping bags and wine bags.

Besides, a variety of exquisitely designed, painstakingly created handicraft and utility items are on display at various shops selling jute goods. Upscale stores like FabIndia and Anokhi are also stocking jute items of various hues nowadays.

“The industry has bright prospects. Earlier, we used to export only sacks to the tune of Rs.800 – 900 crore annually but in the last five to 10 years, the export volume has risen to Rs 1200 crore. The export share of diversified products has risen from 18 to 36 per cent in the last five years”, says Atri Bhattacharya, Secretary of the Jute Manufactures Development Corporation.

India is the world’s largest jute producer, accounting for 2/3rds of the world’s jute production. India exports to the US, Europe and Gulf countries.

India has launched the Jute Technology Mission and the next two years will be significant. If jute products are marketed ably at home and abroad, the Indian jute industry has the potential to double the current turnover of Rs. 5,000 crore, adds Bhattacharya, also the Executive Director, National Centre for Jute Diversification.

The bulk of the jute production in the country comes from West Bengal, Bihar, Assam, Orissa, Andhra Pradesh and Tripura.

Jute goods customers like Subhankar Chatterjee point out that the bio -degradable jute was the best alternative when polythene, plastic and other non-degradable products were choking the global environment.

Consciously buying jute goods is also a great way to support the workers and families involved in this indigenous industry, he adds.

The jute and allied industries have over 2.5 lakh workers and over four and half million people are involved in the jute trade in some manner or the other in India. India has been averaging a production of 1.6 million tones of per annum in the last five years with a domestic market of 1.4 million tonnes.

There was a time, when the jute industry thrived in West Bengal. Jute mills lined the banks of the river Hooghly, providing employment to thousands of people.

Militant Left trade unionism in the state ruined the industry. Of the 63 mills in the state, one closed down 11 years ago and another five years ago. The rest have been operational only intermittently, as per demand.

The operations are being carried out often at half or even one-fourth capacity. With growing awareness for environmental and interest in diversified jute goods, it may be hoped that the golden days of the ‘golden fibre’ would return soon. By Ajitha Menon (ANI)
