NASA’s Swift satellite makes best-ever ultraviolet portrait of Andromeda galaxy

September 17, 2009 By admin Leave a Comment

Washington, September 17 (ANI): NASA’s Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.

The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own.

“Swift reveals about 20,000 ultraviolet sources in M31, especially hot, young stars and dense star clusters,” said Stefan Immler, a research scientist on the Swift team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“Of particular importance is that we have covered the galaxy in three ultraviolet filters. That will let us study M31′s star-formation processes in much greater detail than previously possible,” he added.

M31, also known as the Andromeda Galaxy, is more than 220,000 light-years across and lies 2.5 million light-years away.

On a clear, dark night, the galaxy is faintly visible as a misty patch to the naked eye.

Between May 25 and July 26, 2008, Swift’s Ultraviolet/Optical Telescope (UVOT) acquired 330 images of M31 at wavelengths of 192.8, 224.6, and 260 nanometers.

The images represent a total exposure time of 24 hours.

The task of assembling the resulting 85 gigabytes of images fell to Erin Grand, an undergraduate student at the University of Maryland at College Park who worked with Immler as an intern this summer.

“After ten weeks of processing that immense amount of data, I’m extremely proud of this new view of M31,” she said.

Several features are immediately apparent in the new mosaic.

The first is the striking difference between the galaxy’s central bulge and its spiral arms.

“The bulge is smoother and redder because it’s full of older and cooler stars,” Immler explained. “Very few new stars form here because most of the materials needed to make them have been depleted,” he added.

Dense clusters of hot, young, blue stars sparkle beyond the central bulge.

M31′s disk and spiral arms contain most of the gas and dust needed to produce new generations of stars.

Star clusters are especially plentiful in an enormous ring about 150,000 light-years across.

“Swift is surveying nearby galaxies like M31 so astronomers can better understand star- formation conditions and relate them to conditions in the distant galaxies where we see gamma-ray bursts occurring,” said Neil Gehrels, the mission’s principal investigator at NASA Goddard. (ANI)

Megan Fox tired of fame, sexiness

September 17, 2009 By admin Leave a Comment

Washington, Sep 17 (ANI): It seem that Megan Fox is tired of her fame and sexiness, for she doesn’t want to let people know more about herself.

The 23-year-old actress is currently promoting new film ‘Jennifer’s Body’ at the Toronto International Film Festival.

Although the ‘Transformers’ star never complains about being the hottest female star in Hollywood, she does seem a little tired of all the attention she is getting.

Asked whether playing a high-schooler made her nostalgic for her own high school days, Fox dodged the question saying that she’d instead like to “go back to a time where I didn’t have any responsibility.”

In fact, she seemed wary of the exposure she has had recently.

“I feel like I cling to my privacy and I don’t need to expose myself further to people,” Fox News quoted her as saying. (ANI)

Changes in humidity, temperature may trigger asthma among kids

September 15, 2009 By admin Leave a Comment

Washington, September 15 (ANI): Changes in humidity and temperature may trigger asthma among kids, suggests a report.

Published in the journal Annals of Allergy, Asthma and Immunology, the report says that such weather changes have been found to result in a rise in Emergency Department (ED) visits for paediatric asthma exacerbations.

“We found a strong relationship between temperature and humidity fluctuations with pediatric asthma exacerbations, but not barometric pressure,” said Dr. Nana A. Mireku, an allergist at Dallas Allergy Immunology private practice in Dallas, formerly at Children’s Hospital of Michigan, Wayne State University School of Medicine, Detroit.

“To our knowledge, this is the first study that demonstrated these correlations after controlling for levels of airborne pollutants and common aeroallergens.

“Our study is also one of the few to examine the possibility that the weather one or two days before the asthma exacerbation may be as important as that on the day of admission, as the additional ED visits occur one to two days after the fluctuation,” she added.

The authors of the report write that patients experiencing an asthma attack often complain that weather fluctuations are a major trigger.

Dr. Mireku said: “the latest National Institutes of Health guidelines list ‘change in weather’ as a possible precipitating factor for asthma, but no previous studies have really examined this potential trigger in a rigorous fashion.”

According to the report, the retrospective 2-year study was performed at a large urban hospital of 25,401 children visiting the ED for an asthma exacerbation.

The researchers collected data on climactic factors, pollutants and aeroallergens on a daily basis.

They used time series analysis to evaluate the relationship of daily or between-day changes in climactic factors and asthma ED visits, controlling for seasonality, air pollution and aeroallergen exposure.

The effects of climactic factors were evaluated on the day of admission and up to five days before admission.

The researchers found that a 10 percent daily increase in humidity on a day or two before admission was associated with approximately one additional ED visit for asthma.

The authors write that between-day changes in humidity from two to three days prior to admission were also associated with more ED visits.

Daily changes in temperature on the day of or the day before admission increased ED visits, with a 10 degree F increase being association with 1.8 additional visits.

“Asthma is the most common chronic illness in childhood. Allergists have long known that weather conditions such as extremely dry, wet or windy weather can affect asthma symptoms. This study further defines the role of temperature and humidity on children’s asthma and confirms the importance of working with patients to identify the source of their symptoms and develop treatment plans that help prevent them,” said allergist Richard G. Gower, president of the American College of Allergy, Asthma and Immunology (ACAAI). (ANI)

Scientists develop ‘electronic nose’ that can sniff out toxins by changing colors

September 14, 2009 By admin Leave a Comment

Washington, September 14 (ANI): A team of scientists has developed a sensor that works as an ‘electronic nose’ in sniffing out some known poisonous gases and toxins, simply by changing colors.

Support for the development and application of this electronic nose comes from the National Institute of Environmental Health Sciences, part of the National Institutes of Health.

Once fully developed, the sensor could be useful in detecting high exposures to toxic industrial chemicals that pose serious health risks in the workplace or through accidental exposure.

While physicists have radiation badges to protect them in the workplace, chemists and workers who handle chemicals do not have equivalent devices to monitor their exposure to potentially toxic chemicals.

The investigators hope to be able to market the wearable sensor within a few years.

“The project fits into the overall goal of a component of the GEI Exposure Biology Program that the NIEHS has the lead on, which is to develop technologies to monitor and better understand how environmental exposures affect disease risk,” said NIEHS Director Linda Birnbaum.

“This paper brings us one step closer to having a small wearable sensor that can detect multiple airborne toxins,” she added.

Kenneth S. Suslick, the M.T. Schmidt Professor of Chemistry at the University of Illinois at Urbana-Champaign, and his colleagues have created what they refer to as an optoelectronic nose, an artificial nose for the detection of toxic industrial chemicals (TICs) that is simple, fast, inexpensive, and works by visualizing colors.

“We have a disposable 36-dye sensor array that changes colors when exposed to different chemicals. The pattern of the color change is a unique molecular fingerprint for any toxic gas and also tells us its concentration,” said Suslick.

“By comparing that pattern to a library of color fingerprints, we can identify and quantify the TICs in a matter of seconds,” he added.

The power of this sensor to identify so many volatile toxins stems from the increased range of interactions that are used to discriminate the response of the array.

To test the application of their color sensor array, the researchers chose 19 representative examples of toxic industrial chemicals.

Chemicals such as ammonia, chlorine, nitric acid and sulfur dioxide at concentrations known to be immediately dangerous to life or health were included.

The arrays were exposed to the chemicals for two minutes.

Most of the chemicals were identified from the array color change in a number of seconds and almost 90 percent of them were detected within two minutes. (ANI)

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

September 12, 2009 By admin Leave a Comment

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)

Exposure to second-hand tobacco smoke linked to liver disease

September 12, 2009 By admin Leave a Comment

Washington, September 11 (ANI): People can develop liver disease even when they are exposed to second-hand tobacco smoke, according to a study.

Scientists at the University of California, Riverside (UCR) have found that exposure to second-hand tobacco smoke can lead to non-alcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury wherein fat accumulates in the liver of people who drink little or no alcohol.

For their study, the researchers exposed some mice to second-hand cigarette smoke for a year in the lab, and observed fat build-up in their liver cells, a sign of NAFLD that eventually leads to liver dysfunction.

The researchers focused on two key regulators of lipid (fat) metabolism that are found in many human cells as well: SREBP (sterol regulatory element-binding protein) that stimulates synthesis of fatty acids in the liver, and AMPK (adenosine monophosphate kinase) that turns SREBP on and off.

They found that second-hand smoke exposure inhibits AMPK activity, which, in turn, causes an increase in activity of SREBP.

More active SREBP results in more fatty acids getting synthesized, they say.

The result is NAFLD induced by second-hand smoke, according to the researchers.

“Our study provides compelling experimental evidence in support of tobacco smoke exposure playing a major role in NAFLD development,” said Manuela Martins-Green, a professor of cell biology, who led the study.

“Our work points to SREBP and AMPK as new molecular targets for drug therapy that can reverse NAFLD development resulting from second-hand smoke. Drugs could now be developed that stimulate AMPK activity, and thereby inhibit SREBP, leading to reduced fatty acid production in the liver,” Martins-Green added.

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

Vitamin C can help protect DNA damage of skin cells

September 10, 2009 By admin Leave a Comment

Washington, Sept 10 (ANI): Researchers at the University of Leicester and Institute for Molecular and Cellular Biology in Portugal have found that vitamin C can help protect DNA damage of skin cells and lead to better skin regeneration.

Previous research has shown that DNA repair is upregulated in people consuming vitamin C supplements.

In the new study, the researchers have provided some mechanistic evidence.

The researchers used affymetrix microarray, for looking at gene expression, and the ‘Comet’ assay to study DNA damage

“The exposure to solar ultraviolet radiation increases in summer, often resulting in a higher incidence of skin lesions. Ultraviolet radiation is also a genotoxic agent responsible for skin cancer, through the formation of free radicals and DNA damage,” said lead researcher Tiago Duarte, formerly of the University of Leicester, and now at the Institute for Molecular and Cellular Biology in Portugal.

“Our study analysed the effect of sustained exposure to a vitamin C derivative, ascorbic acid 2-phosphate (AA2P), in human dermal fibroblasts.

“We investigated which genes are activated by vitamin C in these cells, which are responsible for skin regeneration.

“The results demonstrated that vitamin C may improve wound healing by stimulating quiescent fibroblasts to divide and by promoting their migration into the wounded area. Vitamin C could also protect the skin by increasing the capacity of fibroblasts to repair potentially mutagenic DNA lesions,” Duarte added.

The researchers hope that the results will be of great relevance to the cosmetics industry.

“The study indicates a mechanism by which vitamin C could contribute to the maintenance of a healthy skin by promoting wound healing and by protecting cellular DNA against damage caused by oxidation,” said Dr Marcus S. Cooke from the Department of Cancer Studies and Molecular Medicine and Department of Genetics, at the University of Leicester.

“These findings are particular importance to our photobiology interests, and we will certainly be looking into this further,” Cooke added.

The findings have been published in the journal Free Radical Biology and Medicine. (ANI)

Men with high levels of bone lead 6 times more likely to die from heart disease

September 10, 2009 By admin Leave a Comment

Washington, Sept 10 (ANI): Men with high levels of lead in bones are six times more likely to die from heart disease, according to a new study.

Researchers from the Harvard School of Public Health (HSPH) and the University of Michigan School of Public Health found that bone lead was associated with a higher risk of death from all causes, particularly from cardiovascular disease.

“The findings with bone lead are dramatic,” said Marc Weisskopf, assistant professor of environmental and occupational epidemiology at HSPH and lead author of the study.

“It is the first time we have had a biomarker of cumulative exposure to lead and the strong findings suggest that, even in an era when current exposures are low, past exposures to lead represent an important predictor of cardiovascular death, with important public health implications worldwide,” he added.

During the study, the researchers examined 868 participants in the Department of Veterans Affairs Normative Aging Study, a study of aging in men that began in 1963. Blood lead and bone lead were analyzed using X-ray fluorescence.

The results showed that the risk of death from cardiovascular disease was almost six times higher in men with the highest levels of bone lead compared to men with the lowest levels.

The risk of death from all causes was 2.5 times higher in men with the highest levels of lead compared to those with the lowest levels.

According to the authors, there are a number of mechanisms, such as increased oxidative stress, by which lead exposure may result in cardiovascular mortality.

They also note that, in addition to high blood pressure, exposure to lead has been associated with widened pulse-pressure (an indicator of arterial stiffening) and heart disease.

Given that bone lead may be a better biomarker of cumulative lead exposure than blood lead, it may be the best predictor of chronic disease from exposure to lead in the environment.

The study appears in journal Circulation. (ANI)

Noisy roads up high BP risk

September 10, 2009 By admin Leave a Comment

Washington, Sept 10 (ANI): Individuals living near noisy roads are at greater risk of developing high blood pressure, according to a new study.

The study has been published in BioMed Central’s open access journal Environmental Health.

Theo Bodin worked with a team or researchers from Lund University Hospital, Sweden, to investigate the association between living close to noisy roads and having raised blood pressure.

He said, “Road traffic is the most important source of community noise. Non-auditory physical health effects that are biologically plausible in relation to noise exposure include changes in blood pressure, heart rate, and levels of stress hormones.

“We found that exposure above 60 decibels was associated with high blood pressure among the relatively young and middle-aged, an important risk factor for cardiovascular diseases such as heart attack and stroke”.

To reach the conclusion, Bodin and his colleagues used health survey questionnaires for 27,963 people living in Scania in southern Sweden and related this information to how close the respondents lived to busy roads. Modest exposure effects were generally noted in all age groups at average road noise levels below 60 dB(A). More marked effects were seen at higher exposure levels among relatively young and middle-aged people, whereas no effects at higher levels were discerned in the oldest age group (60 – 80 years old).

Speaking about this age-effect, Bodin said, “The effect of noise may become less important, or harder to detect, relative to other risk factors with increasing age. Alternatively, it could be that noise annoyance varies with age”.(ANI)

Porn as bad as guns for kids, says Oz politician

September 10, 2009 By admin Leave a Comment

Melbourne, September 10 (ANI): A senior member of the Liberal Party of Australia has warned against children’s exposure to pornography at home, saying viewing of the restricted material is as dangerous as guns for kids.

Scott Morrison suggested that laws should be introduced Down Under forbidding parents from letting their kids watch the explicit content.

“It is not acceptable to knowingly or negligently expose a child to pornographic material. To do so in my view is child abuse, ” News.com.au quoted Morrison as telling Federal Parliament.

“Even those who would defend an adult’s right to porn would surely not oppose any restriction or sanction placed on parents who knowingly or negligently expose their children to this abuse,” he added.

The 41-year old also said that porn should be treated like dangerous firearms and kept under lock and key to protect youngsters from its risks, that include developing sexually deviant tendencies, committing sexual offences and having difficulties with intimate relationships.

Morrison said: “Any ammunition must be stored in a locked and separate container, it must be put in a locked receptacle which is very solid, and failure to meet these requirements attracts a jail sentence.

“If we can protect our children from guns then we should also be aware of the loaded gun that is lying around in the homes of thousands of Australians on their computer, on their coffee table, in their bathroom or in their bookcase.” (ANI)

Gwyneth Paltrow exposes more than intended in Barcelona

September 8, 2009 By admin Leave a Comment

London, Sep 8 (ANI): American actress Gwyneth Paltrow is said to have exposed more than she intended during an airport security check in Barcelona on September 7.

Paltrow, 36, was preparing for her flight home after seeing hubby Chris Martin, 32, in concert with Coldplay, when the incident took place, reports the Sun.

‘NanoPen’ may revolutionise electronics sector, medical diagnostic tests

September 3, 2009 By admin Leave a Comment

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)

NASA all set to launch infrared eye to hunt for dark asteroids

September 3, 2009 By admin Leave a Comment

Sydney, September 3 (ANI): NASA is preparing to launch an infrared telescope that will hunt down dark asteroids that have slipped beneath our radar.

According to a report by ABC Science, the Wide-field Infrared Survey Explorer (WISE) spacecraft recently arrived at Vandenberg Air Force Base in California ahead of its launch later this year.

With a quartet of infrared sensors and a wide view, WISE is designed to survey the whole sky in infrared light.

It’s not the first telescope to do so, but scientists expect WISE’s observations will be 500 times sharper than a survey conducted in 1980s by IRAS, the Infrared Astronomical Satellite, according to astronomer Martin Cohen of the University of California at Berkeley.

The data will be complied into an all-sky infrared atlas, a tome that is expected to include about 300 million objects, including around 100,000 asteroids.

Many of the asteroids seen by WISE will be known objects.

Scientists hope to use the new observations to nail down details, such as an asteroid’s diameter and surface reflectivity.

“With ground-based scopes, it’s just a point source. You can’t tell size directly,” said University of Texas astronomer Dr Robert McMillan who leads Spacewatch, an asteroid-survey project.

“A big object that is dark and a small object that is bright are going to look like they have the same brightness,” he added.

The solar system contains several million asteroids, most of which reside in the main asteroid belt between Mars and Jupiter.

About 7000 asteroids have been identified that cross or come close to Earth’s orbit.

WISE will be able to spot asteroids emitting heat due to direct exposure from the Sun, as opposed to visible-light searches that find asteroids that are reflecting sunlight.

“Those are two different physical effects,” said McMillan. “An asteroid that has very dark colour in invisible light is going to get heated up more, just like a black car in a parking lot is going to get heated up more than a white car,” he added.

Scientists hope to get enough positioning information to follow up targets with ground-based observations.

McMillan expects that WISE will discover a few hundred new asteroids.

The information will be folded into ongoing surveys to map asteroids that could impact Earth and cause widespread damage.

Other WISE targets include brown dwarfs, which are Jupiter-sized stars that never got their nuclear fusion engines running, and ultra-luminous galaxies, which pump out the equivalent of about 1000 Sun-sized stars every year. (ANI)

Here’s how exposure to diesel fumes causes cancer

September 3, 2009 By admin Leave a Comment

Washington, September 3 (ANI): American scientists have for the first time shown how exposure to diesel fumes causes cancer.

Qinghua Sun, an assistant professor of Environmental Health Sciences at Ohio State University, says that diesel exhaust has the ability to induce the growth of new blood vessels that serve as a food supply for solid tumours.

The researchers found that in both healthy and diseased animals.

According to them, more new blood vessels sprouted in mice exposed to diesel exhaust than did in mice exposed to clean, filtered air.

They say that this finding indicates that previous illness is not required to make humans susceptible to the damaging effects of the diesel exhaust.

The researchers say that inhaled diesel particles are very tiny in size, which is why they can penetrate the human circulatory system, organs, and tissues.

This suggests that diesel fumes can cause damage just about anywhere in the body, they add.

Diesel exhaust exposure levels in the study were designed to mimic the exposure people might experience while living in urban areas and commuting in heavy traffic.

The levels were lower than or similar to those typically experienced by workers who use diesel-powered equipment, who tend to work in mines, on bridges and tunnels, along railroads, at loading docks, on farms and in vehicle maintenance garages, according to the U.S. Department of Labor.

“The message from our study is that exposure to diesel exhaust for just a short time period of two months could give even normal tissue the potential to develop a tumour,” said Qinghua Sun, senior author of the study.

“We need to raise public awareness so people give more thought to how they drive and how they live so they can pursue ways to protect themselves and improve their health. And we still have a lot of work to do to improve diesel engines so they generate fewer particles and exhaust that can be released into the ambient air,” Sun added.

A research article on the study, supported by Health Effects Institute awards and grants from the National Institutes of Health, has been published in the online edition of the journal Toxicology Letters. (ANI)

Victims of workplace bullies can suffer severe sleep problems

September 1, 2009 By admin Leave a Comment

Westchester, September 1 (ANI): Exposure to workplace bullying is associated with increased sleep disturbances, according to a new study.

A study in the Sept.1 issue of the journal ‘Sleep’ claims association between observed bullying and sleep disruption, indicating that bullying has unfavorable effects even when it is experienced indirectly.

It also helps reveal the prevalence of workplace bullying, with 11 percent of women and nine percent of men facing “hostile behavior” in their jobs at least weekly and for at least six months during the previous 12 months.

The other factors such as age, occupation, weekly work hours and depressive symptoms were taken into account too, but yet it was found that exposure to bullying was significantly associated with self-reported sleep disturbances.

The adjusted odds ratio of having disturbed sleep was more than two times higher in men than women who were nearly two times more likely to report having sleep disturbances if they had experienced daily or almost daily bullying or had been exposed to bullying for more than five years.

Principal investigator Isabelle Niedhammer, PhD, epidemiologist and researcher at the UCD School of Public Health and Population Science at the University College Dublin in Ireland believes that exposure to any form of violence or harassment at the workplace may raise the chances of having sleep disturbances.

He said: “Workplace bullying may be considered as one of the leading job stressors and would be a major cause of suicide and other health-related issues.

“Our study underlines the need to better understand and prevent occupational risk factors, such as bullying, for sleep disorders.” (ANI)

Carbon monoxide exposure may up heart problem risk for the elderly

September 1, 2009 By admin Leave a Comment

Washington, Sep 1 (ANI): Carbon monoxide exposure has been found to elevate the risk of hospitalisation for the elderly with heart problems in an American study.

The nationwide study of 126 urban communities has shown that an increase in carbon monoxide of 1 part per million in the maximum daily one-hour exposure is linked with a 0.96 percent increase in the risk of hospitalisation from cardiovascular disease among people over the age of 65.

The connection remains even when carbon monoxide levels are less than 1 part per million, which is well below the Environmental Protection Agency’s (EPA) National Ambient Air Quality Standard of 35 parts per million.

The finding has indicated that an under-recognized health risk to seniors.

Presently, the EPA is evaluating the scientific evidence on the link between carbon monoxide and health to determine whether the health-based standard should be modified.

“This evidence indicates that exposure to current carbon monoxide levels may still pose a public health threat. Higher levels of carbon monoxide were associated with higher risk of hospitalisations for cardiovascular heart disease,” said Michelle Bell, the study’s lead investigator.

Working in collaboration with experts from the Johns Hopkins Bloomberg School of Public Health and the University of Southern California’s Keck School of Medicine, Bell analysed hospital records for 9.3 million Medicare recipients and data on air pollution levels and weather, gathered between 1999 and 2005.

The analysis considered the health effects of other traffic-related pollutants, including nitrogen dioxide, fine particles, and elemental carbon.

“We found a positive and statistically significant association between same-day carbon monoxide levels and an increased risk of hospitalisation for cardiovascular disease in general, as well as for multiple, specific cardiovascular disease outcomes, including ischemic heart disease, heart rhythm disturbances, heart failure and cerebrovascular disease,” said Bell.

Carbon monoxide is a tasteless, odourless gas that is a component of automobile exhaust.

The researchers stressed the need for additional research to investigate whether carbon monoxide or a combination of it and other traffic-related pollutants could result in increased cardiovascular hospitalisations in the elderly.

Their most recent findings have been detailed in a research article published in Circulation: Journal of the American Heart Association. (ANI)

Pak hypnotist vows to change KKR’s fortunes, writes letter to SRK

August 30, 2009 By admin Leave a Comment

Islamabad, Aug.30 (ANI): After having helped the Pakistan cricket team win the ICC World T20 Championship, famous psychotherapist and hypnotist Maqbool ‘Max’ Babri has expressed his interest in holding training sessions for the troubled Indian Premier League (IPL) team, the Kolkata Knight Riders (KKR) to change its fortunes.

Babri has written a letter to KKR owner Shahrukh Khan and the team’s former captain Sourav Ganguly’s brother, Snehashish Ganguly, expressing his desires to be KKR’s ‘mental’coach and ‘thought manager’ for the third season of the IPL.

“I will very much like to be a part of your team as a thought manager and mind coach. People think I am a magician, but I must confess that I am not a magician but certainly what I do appears to be like magic and transforms people to really excel in what they do and makes them happy and buoyant,” Babri stated in his letter.

Interestingly, Babri had predicted that Pakistan, which was considered underdogs in the tournament, would win the T20 World Cup after spending six days with the team ahead of the event.

The Pakistan Cricket Board (PCB) had appointed Babri to help players cope up with pressure and perform well in the T20 World Cuo after the team’s dismal show in previous events and lack of international exposure due the refusal of foreign teams to visit Pakistan citing security reasons, The Nation reports.

Babri is regarded highly in the Pakistan team, with former coach Geoff Lawson describing him as a ‘terrific asset’ for the squad. (ANI)

‘Toxic cocktail’ in tunnels can increase air pollution levels by up to 1,000 times

August 28, 2009 By admin Leave a Comment

Washington, August 28 (ANI): A new study has found that a toxic cocktail of ultrafine particles, which is lurking inside road tunnels, can increase air pollution levels by up to 1,000 times, enough to harm drivers and passengers.

The study measured ultrafine particle concentration levels outside a vehicle travelling through the M5 East tunnel in Sydney.

According to study co-author and director of Queensland University of Technology’s International Laboratory for Air Quality and Health, Professor Lidia Morawska, road tunnels were locations where maximum exposure to dangerous ultrafine particles in addition to other pollutants occurred.

“The human health effects of exposure to ultrafine particles produced by fuel combustion are generally regarded as detrimental,” Professor Morawska said.

“Effects can range from minor respiratory problems in healthy people, to acute myocardial infarction (heart attack) in people with existing heart complaints,” she added.

Professor Morawska said the study involved more than 300 trips through the four kilometres of the M5 East tunnel, with journeys lasting up to 26 minutes, depending on traffic congestion.

“What this study aimed to do was identify the concentration levels found in the tunnel. It generated a huge body of data on the concentrations and the results show that, at times, the levels are up to 1000 times higher than in urban ambient conditions,” she said.

She said that drivers and occupants of new vehicles which had their windows closed were safer than people travelling in older vehicles.

“People who are driving older vehicles which are inferior in terms of tightness and also those riding motorcycles or driving convertibles, these people are exposed to incredibly high concentrations,” she said.

“When compared with similar studies reported previously, the measurements here were among the highest recorded concentrations,” she added.

Professor Morawska said that tunnels were becoming an increasingly necessary infrastructure component in many cities across the world.

“When governments are building tunnels for urban design reasons, they should also consider the impact these tunnels are having on the environment and to people’s health,” she said.

“The study highlights why governments need to consider how they are going to deal with the air pollution levels inside the tunnel and removal of ultrafine particles in the outside environment,” she added. (ANI)
