European company develops mobile robots that are autonomous and multi-tasking

Madrid (Spain), September 19 (ANI): An European company has developed innovative robots which are mobile, multifunctional, collaborative, autonomous and polyvalent, suitable for a wide range of work from street cleaning and rubbish collection to accompanying elderly people.

According to a report carried out in www.basqueresearch.com, this new generation of robots have been developed by TECNALIA Technological Corporation, and are a part of the European DUSTBOT research project under the remit of the VI European Framework Programme and in which TECNALIA is participating.

These latest generation robots are suitable for the monitoring of large spaces (open and closed), as guides for persons in large shopping areas (indicating to them where a particular shop or product is within a shopping centre), for accompanying elderly people or those with certain disabilities (both at home and outside), thanks to their functions of orientation, navigation, communications with others or tele-assistance centres.

They can also be used as guides in teaching spaces (museums, visitor centres), and for transport, storage and transport and goods deliveries, besides the cleaning of both open and closed surfaces, which have either difficult or easy access.

DUSTBOT has collaborative, multifunctional and autonomous robots that are capable of operating in partially destructured environments/situations based on information provided by a map.

The robots can also facilitate working in large areas, stations, airports and other types of public buildings, without being any obstacle for the activity of these places, given its reduced size, and without being a danger for members of the public, thanks to the novel system for the detection and avoidance of obstacles.

The rail station of the Euskotren company in the Bilbao neighbourhood of Atxuri in Spain was chosen for the public presentation of these devices.

The demonstration of two robot models was undertaken: the DustCart and the DustClean.

The DustCart robot, measuring 1.45 metres high and 70 Kg in weight, has a humanoid form and is designed to interact with the user and for the collection of low demand waste.

The DustClean robot, in the form of a small vehicle and measuring 96 cm high and 250 Kg in weight, cleans streets of dirt and dust. Moreover, both control the quality of air in real time.

“These robots are the solution for cleaning areas of difficult access and for the collection of rubbish at the very front door of, above all, persons who have mobility problems when moving the rubbish to the communal waste containers,” said Inaki Inzunza, Director of the Business Unit at the Tecnalia Technological Corporation.

Brit men having moob jobs on the rise

London, Sep 18 (ANI): It has emerged that more and more Brit men are having cosmetic surgery to get rid of their “moobs”.

According to the British Association of Aesthetic Plastic Surgeons (BAAPS), there has been a 44 per cent year-on-year rise in the number of men wanting to get rid of their ‘man boobs’.

The AGM of BAAPS in Cardiff heard that the procedure is now the fifth most popular cosmetic op for men, with more than 1,000 men forking out more than 2,000 pounds to get rid of their flabby breasts in the last 12 months.

Delegates were told over the past five years the numbers of men losing their moobs have shot up by an amazing 1,000 per cent.

“We are seeing men of all ages coming in to have their breasts made smaller,” the Sun quoted plastic surgeon Douglas McGeorge as saying.

“They are losing their inhibitions about the operation and deciding to undergo an operation which previously was a women’s operation,” he said.

McGeorge, who is based in Chester, revealed that a recent patient, who had never taken his shirt off, was typical of the men queuing up for the op.

“It was a grandfather who had never taken off his T-shirt in his life because he was so embarrassed about the size of his breasts,” he said.

“He had never been able to strip to the waist on the beach in front of his own children – but was determined not to be in the same position with his grandchildren,” he stated.

The moob jobs pushed out facelifts to become the fifth most popular plastic surgery for British men after nose jobs, eyelifts, ear corrections, and liposuction.

“Reasons for the upsurge include men being more open now about their physique than years ago,” plastic surgeon Fazel Fatah said.

“And they can get more and more information about it from internet sites which encourage them to have the op,” he added. (ANI)

Negative public opinion about foreign countries an early warning signal for terrorism

Washington, September 18 (ANI): People’s negative views toward the leadership and policies of other countries may be an indication that a terrorist act may be carried out, say researchers.

Alan Krueger, a Princeton University economist, and Jitka Maleckova, of Charles University in the Czech Republic, came to this conclusion after analysing public opinion polls and terrorist activity in 143 pairs of countries.

Writing about their findings in the journal Science, the researchers say that there is a strong relationship between attitudes expressed toward a foreign country — indicated in surveys on foreign leaders’ performance-and the occurrence of terrorism against that country.

“Public opinion appears to be a useful predictor of terrorist activity,” said Krueger, the Bendheim Professor in Economics and Public Policy.

“This is the first study to relate public opinion across countries to concrete actions such as terrorism,” he added.

He pointed out that the notion that public attitudes can contribute to terrorism has been inadequately explored to date.

According to him, the study’s findings attain significance as they suggest that public opinion may provide a valuable early warning signal of terrorism, and help researchers better understand the causes of terrorism.

The researchers carried out their study by mining public opinion polls of residents in 19 countries in the Middle East and northern Africa conducted by Gallup.

They asked the respondents whether they approved of the job performance of the leaders of nine large countries.

According to the researchers, the countries selected for the study are world powers in terms of size, population or military strength, are the United States, Canada, China, France, Germany, India, Japan, Russia and the United Kingdom.

The opinions, both positive and negative, were linked to the number of terrorist attacks conducted against the nine world powers by people from the 19 countries between 2004 and 2008. The terror attacks were compiled by the National Counterterrorism Center.

Based on the findings, Krueger says that there is not a direct connection between poverty and terrorism, contrary to a popular view.

He adds that economic status has more to do with target countries than it does with the states where the attacks originate.

He says that countries with advanced economies as well as a high degree of civil liberties are most likely to be the targets of terrorism.

The researchers admits that the study does not explain whether terrorists act in response to public opinion or whether they are simply reacting just like the larger public to external events.

However, he insists that, in either case, public opinion surveys can provide a powerful indication of the likelihood of terrorist activity.

Krueger believes that greater disapproval of another country’s leaders or policies may result in more terrorist acts because it increases the number of people who provide material support and encouragement for terrorism, and increases the number of people interested in joining cells and carrying out terrorist acts themselves.

Catalyst simulations for fuel cells may make clean cars a reality

Washington, Sep 18 (ANI): University of Wisconsin-Madison researchers are working towards developing better catalyst for fuel cells in a bid to make clean cars a reality.

If successful, the researchers could make a car that runs on hydrogen from solar power, and produces water instead of carbon emissions.

Materials science and engineering assistant professor Dane Morgan and Ph.D. student Edward (Ted) Holby have developed a computational model that could optimise an important component of fuel cells, making it possible for the technology to have a more widespread use.

The researchers investigated how particle size is related to the overall stability of a material, and showed with their model that increasing the particle size of a fuel cell catalyst decreases degradation and therefore increases the useful lifetime of a fuel cell.

Fuel cells are electrochemical devices that facilitate a reaction between hydrogen and oxygen, producing electrical power and forming water.

In the type of fuel cells Morgan is researching, called proton exchange membrane fuel cells (PEMFCs), hydrogen is split into a proton and electron at one side of the fuel cell (the anode).

The proton moves through the device while the electron is forced to travel in an external circuit, where it can perform useful work, while at the other side of the fuel cell (the cathode), the protons, electrons and oxygen combine to form water, which is the only waste product.

One of the many hurdles to producing efficient fuel cells for widespread use is the catalyst added to aid the reaction between protons, electrons and oxygen at the cathode.

Current fuel cells use platinum and platinum alloys as a catalyst. While platinum can withstand the corrosive fuel cell environment, it is expensive and not very abundant.

Thus, to maximize platinum use, researchers use catalysts made with platinum particles as small as two nanometers, which are approximately 10 atoms across.

These tiny structures have a large surface area on which the fuel cell reaction occurs.

However, platinum catalysts this small degrade very quickly, which means that the fuel cell doesn’t last long.

The researchers have found a possible solution to the rapid degradation problem-when it comes to catalyst particle size, sometimes smaller isn’t better.

In their modelling work, they showed that if the particle size of a platinum catalyst is increased to four or five nanometers, which is approximately 20 atoms across, the level of degradation significantly decreases.

This means the catalyst and the fuel cell as a whole can continue to function for much longer than if the particle size was only two or three nanometers.

“Fuel cells are just one of many energy technologies – solar, battery, etc. – with enormous potential to reduce our dependence on oil and our carbon emissions. Computer simulation offers a powerful tool to understand and develop new materials at the heart of these energy technologies,” said Morgan. (ANI)

Scientists find meteorite that came from innermost asteroid belt between Mars and Jupiter

Washington, September 18 (ANI): In a very rare finding, scientists have discovered an unusual kind of meteorite in the Western Australian desert and have uncovered that it came from the innermost main asteroid belt between Mars and Jupiter.

Meteorites are the only surviving physical record of the formation of our Solar System.

However, information about where individual meteorites originated, and how they were moving around the Solar System prior to falling to Earth, is available for only a dozen of around 1100 documented meteorite falls over the past two hundred years.

According to Dr Phil Bland from the Department of Earth Science and Engineering at Imperial College London, the lead author of the study, “We are incredibly excited about our new finding. Meteorites are the most analysed rocks on Earth, but it’s really rare for us to be able to tell where they came from.”

The new meteorite, which is about the size of cricket ball, is the first to be retrieved since researchers from Imperial College London, Ondrejov Observatory in the Czech Republic, and the Western Australian Museum, set up a trial network of cameras in the Nullarbor Desert in Western Australia in 2006.

The researchers aim to use these cameras to find new meteorites, and work out where in the Solar System they came from, by tracking the fireballs that they form in the sky.

The new meteorite was found on the first day of searching using the new network, by the first search expedition, within 100m of the predicted site of the fall.

The meteorite appears to have been following an unusual orbit, or path around the Sun, prior to falling to Earth in July 2007, according to the researchers’ calculations.

The team believes that it started out as part of an asteroid in the innermost main asteroid belt between Mars and Jupiter.

It then gradually evolved into an orbit around the Sun that was very similar to Earth’s.

The new meteorite is also unusual because it is composed of a rare type of basaltic igneous rock.

According to the researchers, its composition, together with the data about where the meteorite comes from, fits with a recent theory about how the building blocks for the terrestrial planets were formed.

This theory suggests that the igneous parent asteroids for meteorites like today’s formed deep in the inner Solar System, before being scattered out into the main asteroid belt.

Asteroids are widely believed to be the building blocks for planets like the Earth, so the new finding provides another clue about the origins of the Solar System. (ANI)

Mayawati slams Congress party’s austerity drive

Lucknow, Sep 18 (ANI): Uttar Pradesh Chief Minister Mayawati has ridiculed Congress party’s austerity drive, terming it as a ploy to steer attention away from the steep price rise.

Addressing a mass rally here on Thursday, Mayawati hit out at the Congress party, calling its austerity drive “a drama.”

“Because of the wrong doings by the Congress government at the centre, the prices are rising due to which poor people across the country are suffering. And now to cover up its weaknesses, they have cut down on its travelling expenses by flying economy class and travelling by train. All this is just a drama,” Mayawati said.

“With a drought looming and elections in some states approaching, the Congress-led government has embarked on a much-publicised austerity drive,” she added.

In a country where the hierarchy of politicians is determined by the size of their bungalows and their convoys, Congress Party President Sonia Gandhi has asked party leaders to give up a fifth of their salaries for drought-relief work, and she flew economy class on a commercial flight to Mumbai to launch the poll campaign.

The finance ministry has appealed for fewer overseas trips with smaller entourages, and a ban on conferences in luxury hotels.

Bharatiya Janata Party and other political parties have criticised the austerity measures in view of the economic downturn and drought-like situation prevailing in the country as a case of ‘tokenism’. (ANI)

Scientists map melting history of Greenland’s ice sheet

Washington, September 17 (ANI): Researchers from the Niels Bohr Institute at the University of Copenhagen have mapped the history of the melting of the Greenland ice sheet.

Numerous drillings have been made through both Greenland’s ice sheet and small ice caps near the coast.

By analyzing every single annual layer in the kilometres long ice cores, researchers can get detailed information about the climate of the past.

But now, the Danish researcher Bo Vinther and colleagues from the Centre for Ice and Climate at the Niels Bohr Institute, University of Copenhagen, in collaboration with researchers from Canada, France and Russia, have found an entirely new way of interpreting the information from the ice core drillings.

“Ice cores from different drillings show different climate histories. This could be because they were drilled at very different places on and near Greenland, but it could also be due to changes in the elevation of the ice sheet, because the elevation itself causes different temperatures,” explained Bo Vinther about the theory.

Today, the ice sheet is more than three kilometres thick at its highest point and thinning out towards the coast.

Four of the drillings analyzed are from the central ice sheet, while two of the drillings are from small ice caps outside of the ice sheet itself.

By comparing the Oxygen-18 content in all of the annual layers from the four drillings through the ice sheet with the Oxygen-18 content of the same annual layers in the small ice caps, Bo Vinther has calculated the elevation course through 11,700 years.

Just after the ice age the elevation of the ice sheet rose slightly because when the climate transitions from ice age to warm age, there is a rapid increase in precipitation.

But at the same time, the areas lying near the coast begin to decrease in size, because the ice is melting at the edge.

When the ice melts at the edge, it slowly causes the entire ice sheet to ‘collapse’ and become lower.

The calculations show that in the course of about 3,000 years, the elevation changed and became up to 600 meters lower in the coastal areas.

But in the middle, it was a slow process, where the elevation decreased around 150 meters in the course of around 6,000 years.

It then stabilized.

The new results show the evolution of elevation of the ice sheet throughout 11,700 years and they show that the ice sheet is very sensitive to the temperature.

The results can be used to make new calculations for models predicting future consequences of climate changes. (ANI)

Study on sheep shows link between personality, survival, and reproductive success

Washington, September 16 (ANI): Canadian researchers have established a link between personality, survival, and reproductive success by carrying out a study on male bighorn sheep.

Denis Reale, a professor in the Department of Biological Sciences at UQAM and Canada Research Chair in Behavioural Ecology, says that the new study offers insight into personality differences in animals and humans, from an evolutionary perspective.

Since 1969, several teams of researchers have been studying this population of bighorn sheep in Alberta, Canada. They have collected considerable data over the years.

Working in collaboration with researchers from the University of Sherbrooke and the University of Alberta, Reale identified the rams in terms of boldness and docility.

The researchers then conducted paternity tests to determine which rams were reproducing.

They point out that in a system like that of bighorn sheep where there is strong competition among the males for impregnating females, large size and high dominance status are normally key factors in a male’s success.

Males usually attain these conditions in the prime of life, between 6 and 12 years, the researchers say.

However, the paternity tests showed that some young males manage to fertilize females.

The researchers also concentrated on the risk associated with participation in the rut-males can be injured or fall from a cliff in fighting.

Reale and his colleagues hypothesized that the young males that manage to reproduce would be the boldest and most combative, and analysis of the data confirmed it.

However, in exchange for sexual precocity and risk-taking, these rams often die younger than their more docile peers. The latter, instead, invest in the long term, breed later and reach an older age.

Based on their observations, the researchers came to the conclusion that their findings indicate a variation in the personalities and life histories of the population, with two extreme types: one that could be characterised as “live fast and die” and the other as “slow and steady wins the race”.

Depending on their personality, the males managed to breed and to transmit their genes, but in different ways.

The study demonstrates that personality has a direct influence on the lifestyle of individuals.

A research article describing the study has been published in the Journal of Evolutionary Biology. (ANI)

Men worry more about mates’ beliefs rather than partners’ when it comes to size of penis

Melbourne, September 16 (ANI): An Australian study suggests that men seem to be more concerned about what their mates think rather than their partners, when it comes to the stature and size of their penis.

Annabel Chan, a PhD student at Melbourne’s Victoria University who obtained penis measurements from more than 500 men worldwide, describes this phenomenon as the “locker room syndrome”.

She has revealed that the men also answered questions designed to probe the link between penis size, male body image and mental health.

“It’s the locker room syndrome,” the Courier Mail quoted her as saying.

“That’s when they feel they should be bigger whereas when they are on their own they are actually quite happy with themselves,” she added.

During the study, the researchers asked the men, aged 18 to 76, to indicate their ideal body size, and compare that to what they believed other men would nominate.

About 65 per cent of the participants said that their ideal male body size would be smaller than the ideal size suggested by others.

The men were also asked whether they believed they would be a better sexual partner if they had a bigger penis.

Chan said: “(The men were) more concerned about how their overall body-size compared to the perceived male ideal than they are about how their size might impact on their sexual relations.”

The online survey asked men to measure their erect penises.

Chan said that she expected to receive some overstated measurements, but the self-reported data fell within the normal range of about 10 to 15cm.

“I thought people would report themselves as being very big, but they have been quite average,” she said.

The study showed that men with larger than average penises also reported higher levels of self-esteem, better general health and higher overall body satisfaction.

It further revealed that men who were happy with the size of their penis were also less likely to have used an online dating service, or to have used Viagra.

Overweight men had lower self-esteem, higher body dissatisfaction and greater use of the Internet for socialising, said the researchers.

“We have relatively little data about the body image of men because most of the research in this area concentrates on women,” Chan said.

“It means men don’t really get much help in terms of therapy, and options out there to get help,” she added. (ANI)

Shoe throwing Iraqi journalist’s release from jail postponed by a day

Baghdad, Sep. 14 (ANI): Iraq has postponed the release of the journalist who threw his shoe at former US President George W Bush in Baghdad last year.raqi television journalist Muntazer al-Zaidi will be released from prison a day later than expected, his brother said.

“He called me from the prison and said ‘they won’t release me today, they will free me tomorrow’,” The Telegraph quoted Durgham al-Zaidi, as saying in tears.

Zaidi, 30, was initially sentenced to three years for assaulting a foreign head of state but had his jail time reduced to one year on appeal. He is being freed early because of good behaviour.

Zaidi shouted “it is the farewell kiss, you dog,” at Bush on December 14 last year, seconds before hurling his size-10 shoes at the man who ordered Iraq be invaded and occupied six-and-a-half years ago.

Although Bush, who successfully ducked to avoid the speeding footwear, laughed off the attack, the incident caused massive embarrassment, to both him and Iraqi Prime Minister Nouri al-Maliki.

Zaidi faces the prospect of a very different life from his previous existence as a journalist for Al-Baghdadia television, a small, privately owned Cairo-based station, which has continued to pay his salary in jail.

Zaidi’s boss has promised the previously little-known reporter a new home as a reward for loyalty and the publicity that his actions, broadcast live across the world, generated for the station.

But there is talk of plum job offers from bigger Arab networks, lavish gifts such as sports cars from businessmen, a celebrity status, and reports that Arab women from Baghdad to the Gaza Strip want his hand in marriage. (ANI)

Weight gain in adulthood linked to prostate cancer risk

Washington, Sep 12 (ANI): Body size and weight gain in younger and older adulthood may help weigh a man’s proneness to prostate cancer, according to a study by researchers at the University of Hawaii at Manoa’s Cancer Research Center of Hawaii.

Led by Dr. Brenda Hernandez, the researchers said that the risk varies among different ethnic groups

For the study, the researchers studied the relationship in a multiethnic population consisting of blacks, Japanese, Hispanics, Native Hawaiians and whites, and compared differences among age groups using the Multiethnic Cohort, a longitudinal study of men 45-75 years of age established in Hawaii and California from 1993-1996.

Of the 83,879 men who participated in the study, 5,554 developed prostate cancer.

Overall, men who were overweight or obese by age 21 had a decreased risk of localized and low-grade prostate cancer, according to Hernandez.

Their results suggested that being overweight in older adulthood was associated with increased prostate cancer risk among white and Native Hawaiian men, but a decreased risk among Japanese men.

While excessive weight gain between younger and older adulthood was observed to increase the risk of advanced and high-grade prostate cancers in white men and increase the risk of localized and low-grade disease in black men, it appeared to decrease the risk of localized prostate cancer in Japanese men.

“The relationship of certain characteristics, such as body size, with cancer risk may vary across ethnic groups due to the combined influence of both genes and lifestyle,” said Hernandez.

However, the relationship between body size and prostate cancer risk is not entirely understood.

Excess fat is associated with a number of conditions that contribute to cancer development including low-grade chronic inflammation, insulin resistance, metabolic abnormalities, and hormone imbalances.

These conditions may in turn contribute to more aggressive prostate malignancies.

Ethnic differences in cancer risk may be explained by differences in the distribution of stored body fat that could have a differential effect on the development of prostate cancer.

And the distribution of body fat may influence the specific way that excess fat influences cancer risk.

The study has been published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. (ANI)

Giant eagle filled the role of a predator on Kiwi island 750 years ago

Washington, September 12 (ANI): In a new study, scientists have determined that the role of a predator, before humans colonized New Zealand about 750 years ago, was filled by a giant, extinct raptor known as Haast’s eagle.

Although the bones of Haast’s eagle have been known for well over a century, the behavior of these giants has been a point of debate.

Owing to their large size – these eagles weighed up to 40 lbs., larger than any modern eagle – some scientists believe they were scavengers rather than predators.

The new study, by Paul Scofield of the Canterbury Museum in New Zealand and Ken Ashwell of the University of New South Wales, used computed axial tomography (CAT/CT) scans to reconstruct the size of the brain, eyes, ears and spinal cord of this ancient eagle.

These data were compared to values from modern predatory and scavenging birds to determine the habits of the extinct eagle.

The results indicated not only that Haast’s eagle was a fearsome predator that probably swooped on its prey from a high mountain perch, but also that it evolved over a relatively short period of time from a much smaller-bodied ancestor.

“This work is a great example of how rapidly evolving medical techniques and equipment can be used to solve ancient mysteries,” said Ashwell, co-author of the study.

It is also an example of how the oral traditions of ancient peoples and scientific research can sometimes reach the same conclusion.

“This science supports Maori (native New Zealander) mythology of the legendary pouakai or hokioi, a huge bird that could swoop down on people in the mountains and was capable of killing a small child,” said Paul Scofield, lead author of the study.

Haast’s eagle became extinct a mere 500 years ago, probably due to habitat destruction and the extinction of its prey species by early Polynesian settlers. (ANI)

Killer whales have to raise their voices to be heard over ship noise

Washington, September 11 (ANI): A new research has determined that killer whales have to raise their voices to be heard over ship noise, and the effort may be wearing the whales out as they try to find food amid dwindling numbers of salmon.

According to a report in National Geographic News, scientists at the National Oceanic and Atmospheric Administration (NOAA) carried out the research.

The research indicates that the killer whales of Puget Sound, a complex of inland marine waterways in the northwestern part of Washington, US, make more calls and clicks while foraging than while traveling, suggesting that such mealtime conservations are key to coordinating hunts.

“(The killer whales’) call exchange is incredibly important, and vessel noises have the potential to mask these calls,” said research leader Marla Holt of Seattle’s Northwest Fisheries Science Center, which is run by the National Oceanic and Atmospheric Administration (NOAA).

Holt and colleagues’ previous research had shown that some killer whales make louder calls to be heard over vessel rumblings-just as people raise their voices to talk over the din of a cocktail party.

Now, the researchers think the cacophony could be causing the region’s killer whales to use up more energy during hunts, even as their preferred prey, chinook salmon, are on the decline.

In Puget Sound, a small group of killer whales known as the Southern Residents has been found to be particularly well-suited to eating salmon-even down to the whales’ tooth size.

These animals don’t eat seals or other mammals, as do the transient killer whales that migrate through the sound.

In the mid- to late 1990s, the Southern Resident population mysteriously shrank by nearly 20 percent, from 97 to 88 animals. Today, there are 85 individuals.

In 2005, the federal government listed the population as endangered under the US Endangered Species Act.

No one knows for sure, but the cause was likely a combination of fewer salmon, exposure to toxic contaminants, and vessel noise, according to Lynne Barre of NOAA’s National Marine Fisheries Service Northwest Regional Office.

Holt’s work adds to existing data that have already prompted NOAA to propose a new killer whale protection law that would make all boats keep at least 600 feet (200 yards) away from the animals around Washington State.

The existing law allows boats to approach as close as 300 feet (100 yards), and some research has shown this influences the whales’ behavior.

“A lot of people would argue, Why focus on these vessel regulations?” Holt said. “But it’s one thing we can do immediately,” he added. (ANI)

New blast-proof glass would be less vulnerable to small-scale explosions

Washington, September 11 (ANI): University of Missouri (MU) researchers are developing and testing a new type of blast-proof glass that will be thinner, lighter and less vulnerable to small-scale explosions.

“Currently, blast-resistant window glass is more than 1 inch thick, which is much thicker than standard window glass that is only one-fourth of an inch thick and hurricane-protected window glass that is one-half of an inch thick,” said Sanjeev Khanna, associate professor of mechanical and aerospace engineering in the MU College of Engineering.

“The glass we are developing is less than one-half of an inch thick. Because the glass panel will be thinner, it will use less material and be cheaper than what is currently being used,” he added.

Conventional blast-resistant glass is made with laminated glass that has a plastic layer between two sheets of glass.

MU researchers are now replacing the plastic layer with a transparent composite material made of glass fibers that are embedded in plastic.

The glass fibers add strength because, unlike plastic, they are only about 25 microns thick, which is about half the thickness of a typical human hair, and leave little room for defects in the glass that could lead to cracking.

“The use of a transparent composite interlayer provides us the flexibility to change the strength of the layer by changing the glass fiber quantity and its orientation,” Khanna said.

In tests, researchers are observing how the glass reacts to small-scale explosions caused by a grenade or hand-delivered bomb.

They tested the glass by exploding a small bomb within close proximity of the window panel.

After the blast, the glass panel was cracked, but had no holes in the composite layer.

“The new multilayered transparent glass could have a wide range of potential uses if it can be made strong enough to resist small-scale explosions,” Khanna said.

“The super-strong glass also may protect residential windows from hurricane winds and debris or earthquakes,” he added.

Future tests will be done on larger pieces of glass that are equivalent to standard window size, and researchers could potentially test the glass on large-scale explosions. (ANI)

Barrage of small meteorite impacts cause the moon to “hum”

London, September 9 (ANI): A new research has suggested that a steady barrage of small meteorite impacts cause the moon to “hum”.

But, no seismometers sent to the moon to date have been sensitive enough to hear the “hum”.

According to a report in New Scientist, Philippe Lognonne at the Institute of Earth Physics of Paris and colleagues decided to work out how loud the ring is.

The team estimated the meteorite population in the solar neighbourhood, and calculated the likely seismic signals that would be created by a range of meteorite sizes and velocities as they strike the moon.

To determine how the vibrations from these impacts would be seen by seismometers, the team used data taken by Apollo seismometers four decades ago.

These measured the vibrations created by the landings of lunar modules and spent rocket stages.

Since the precise locations and timing of these landings were known, they could be used to gauge how long it would take vibrations caused by meteorite impacts to travel through the moon, and how much the signals might dim.

Their calculations revealed space rocks with masses ranging from a gram to a kilogram do indeed create a hum, but it is subtle.

Earth’s hum, created by pounding waves, is more than 1000 times louder.

“This shows that all planets may hum, those with and those without atmosphere,” said Lognonne.

“The moon-hum’s quietness means future lunar seismometers should be able to peek deep within the moon without the hum creating problematic background noise, he added.

Instead, seismometers can focus on measuring waves created by moonquakes, tremors created by a variety of sources, including the tidal tug of the Earth.

Because seismic waves are sensitive to the type, arrangement and density of rocks they pass through, studying the quakes can reveal more about the moon’s interior.

The network of seismometers left by the Apollo missions has been shut down since 1977, so Lognonne hopes more sensitive instruments will be sent to the moon soon.

These could reach deeper than the Apollo network to measure the size of the moon’s core.

“I think the study is a great idea,” said Clive Neal of the University of Notre Dame in Indiana, who was not associated with the research.

“Estimating the actual background noise is critical for designing the next generation of seismometers to go to the moon,” he added. (ANI)

Queen Victoria’s 52-inch waist knickers go for £600 at auction

London, Sep 8 (ANI): A bizarre heirloom of the Royal Family has emerged in the form of a pair of oversized knickers belonging to Her Majesty Queen Victoria.

The linen “split drawers”, which had been hidden in a private collection for 100 years, measured 52 inches around the waist, and were sold at auction for 600 pounds to the Royal Ceremonial Dress Collection charity.

The bloomers, which are a size 38, were on September 7 displayed by Kensington Palace warder Victoria Wright, 22, reports the Sun.

They have an embroidered crown and VR – Victoria Regina, and may go on show when a 12 million pounds overhaul of royal outfits is completed in 2012 at the Palace in central London. (ANI)

Novel minimally invasive surgery for treating spinal cancer patients

Washington, Sep 8 (ANI): Doctors at Toronto Western Hospital have come up with a new minimally invasive, outpatient spine surgical procedure for treating cancer that has spread to the spine.

It is believed that almost 40-50 percent of metastic cancers end up in the spine and the most common primary cancers to spread to the bones of the spine are breast and lung cancer.

Spinal tumours can drastically affect a patient’s quality of life and result in pain and reduced mobility.

A spinal tumour or a growth of any kind can impinge on nerves, leading to pain, neurological problems and sometimes paralysis.

The new procedure involves a small incision in the back (the size of a loonie) in order to remove the tumour and stabilize the damaged spine.

Other than providing a shorter recovery time, its benefits also include allowing patients to receive radiation treatment shortly after surgery.

Traditional surgical methods involve a longer and more painful recovery process, thus making patients to wait weeks before resuming radiation treatment.

The combination of surgery and radiation leads to better outcomes and quality of life. (ANI)

Rat as big as a cat found in extinct volcano in Papua New Guinea

London, September 7 (ANI): An expedition team has found a new species of giant rat in an extinct volcano in the jungle of Papua New Guinea, which at 82cm length, is as big as a cat.

According to a report by BBC News, the creature, which has not yet been formally described, was discovered by an expedition team filming the BBC programme ‘Lost Land of the Volcano’.

The rat, which has no fear of humans, is among the largest species of rat known anywhere in the world.

Like the other exotic species, the rat is believed to live within the Mount Bosavi crater, and nowhere else.

“This is one of the world’s largest rats. It is a true rat, the same kind you find in the city sewers,” said Dr Kristofer Helgen, a mammalogist based at the Smithsonian National Museum of Natural History who accompanied the BBC expedition team.

Initially, the giant rat was first captured on film by an infrared camera trap, which BBC wildlife cameraman Gordon Buchanan set up in the forest on the slopes of the volcano.

The expedition team, from the BBC Natural History Unit, recorded the rat rummaging around on the forest floor, and was awed by its size.

Immediately, they suspected it could be a species never before recorded by science, but they needed to see a live animal to be sure.

Then trackers accompanying the team managed to trap a live specimen.

“I had a cat and it was about the same size as this rat,” said Buchanan.

The trapped rat measured 82cm in length from its nose to its tail, and weighed approximately 1.5kg.

It had a silver-brown coat of thick long fur, which the scientists who examined it believe may help it survive the wet and cold conditions that can occur within the high volcano crater.

The location where the rat was discovered lies at an elevation of over 1,000m.

Initial investigations suggest the rat belongs to the genus Mallomys, which contains a handful of other out-sized species.

It has provisionally been called the Bosavi woolly rat, while its scientific name has yet to be agreed.

Mount Bosavi, where the new rat was found, is an extinct volcano that lies deep in the remote Southern Highlands of Papua New Guinea.

The expedition team entered the crater to explore pristine forest, where few humans have set foot.

The island which includes Papua New Guinea and New Guinea is famous for the number and diversity of the rats and mice that live there. (ANI)

Enhancement of India, Russia trade ties

Moscow, Sep 3 (ANI): President Pratibha Devisingh Patil has expressed a desire to enhance bilateral trade ties with Russia.

While addressing a gathering of expatriate Indians and some prominent Russians during the course of her five-day visit, Patil said, the only area where India-Russia relationship is lagging is in the field of bilateral economic cooperation.

“When I look at our relationship, if there is anywhere I feel we are lagging behind, it is in the field of bilateral economic cooperation. For two economies with GDP’s of this size, economic structures that only point to our strong complementarities, close political ties, at all levels of government and strong desire of political leadership of both the sides to foster closer ties, India-Russia bilateral trade and investment ties remain much too modest,” Patil added.

Acknowledging the work done by the expatriate Indian community towards enhancing ties between both the countries, Patil said, “All of you have been working in some capacity or the other with India-Russia collaborators projects. It is your work that has provided the building blocks to the India-Russia strategic partnership.”

Reportedly, Russia is keen to double the trade with India to 10 billion dollars by 2010 and cement Indo-Russian relations despite trade with India lagging far behind Moscow’s economic ties with the European Union and China.

Russia sees India, a staunch ally of the erstwhile Soviet Union during the Cold War era, as an important partner to expand Russian influence in Asia, though Moscow and New Delhi have bickered over delays in the delivery of Russian military hardware.

Russia is aiding in the setting up of two 1,000-megawatt nuclear reactors at Kudankulam as part of a deal signed in 1988. Russia agreed in 2008 to build four more reactors at the site. By Pankaj Choudhary (ANI)

‘NanoPen’ may revolutionise electronics sector, medical diagnostic tests

Washington, September 3 (ANI): A team of scientists in California have announced the creation of a ‘NanoPen’ that can simplify the method of laying down patterns of nanoparticles-from wires to circuits-for making futuristic electronic devices, medical diagnostic tests, and other much-anticipated nanotech applications.

Writing about their work in ACS’ Nano Letters, Ming Wu and colleagues point out that researchers have already developed several different techniques for producing patterns of nanoparticles, which are barely 1/50,000th the width of a human hair.

However, the researchers add, current techniques tend to be too complex and slow because they require bulky instrumentation and take minutes or even hours to complete.

The researcher further point out that these techniques also require the use of very high temperatures to apply the nanostructures to their target surfaces.

According to them, such limitations prevent widespread application of these techniques.

They claim that their NanoPen can solve all these problems.

The researchers have used the novel device in their lab to deposit various nanoparticles into specific patterns in the presence of relatively low light and temperature intensities.

They say that the process, which requires the use of special “photoconductive” surfaces, takes only seconds to complete with their NanoPen.

They further state that manufacturers can adjust the size and density of the patterns by adjusting the voltage, light intensity, and exposure time applied during the process. (ANI)
