Four hours a day on computers ‘can double heart disease risk’
Just four hours a day in front of a computer or television could double your risk of a heart disease and thus increase your chances of premature death, a new study has claimed.
Researchers at the University College London have found that people who work on computers or watch television for four or more hours a day are 125 per cent more likely to suffer a major heart problem, often leading to death, than those who spend two hours or less.
And the study also found there is also a 48 per cent increase in deaths from any cause among people who spend too much time staring at a screen, the Daily Express reported.
Even exercise could not make up for the damage caused, say the researchers.
According to the researchers, inflammation and metabolic problems caused by long periods of inactivity could be to blame for the increased risks —— prolonged sitting could cause a 90 per cent reduction in a vital enzyme, lipoprotein lipase, that helps prevent heart disease.
Dr. Emmanuel Stamatakis of University College London’s public health department, who led the study, said: “Our analysis suggests that two or more hours of screen time each day may place someone at greater risk for a cardiac event.
“People who spend excessive amounts of time in front of a screen are more likely to die of any cause and suffer heart—related problems.”
The researchers have advised people who work in front of a computer to reduce their risk by taking breaks for a brief walk every 20 minutes.
Stamatakis said: “Standing and moving about results in at least 50 per cent more energy expenditure than sitting down so such approaches may also be very promising for tackling the obesity epidemic.
“A totally feasible and realistic redesign of the workplace and home environments can easily convert long periods of time during the workday that currently are strictly sedentary into a mixture of sitting, standing and light intensity activity. This would be an excellent start.
“TV watching should be a key target of public health interventions. Heart disease and poor health in general is not only the result of high cholesterol, diets high in fat, smoking and low exercise.”

The Changing Role of Libraries in the Digital Age
"We believe that free communication is essential to the preservation of a free society and a creative culture. ~ American Library Association
Since the founding of our country, libraries have always been important to freedom. Today we are in the midst of a tremendous shift in the way Americans consume literature and other content, but one thing has not changed -- the library must continue to play a central role in providing open and free access to information and ideas.
Exactly what that role looks like is the subject of much debate and many differing perspectives. Some believe libraries will shift into learning and information centers while others insist they will maintain their role as a physical location for cataloging and loaning books -- in addition to housing sources of information technology.
While providing books was a standalone function for libraries throughout the last few centuries, their offerings have evolved with the digital age to meet the changing needs of their patrons. In fact, according to an article in the November 2009 issue of American Libraries, more than 71 percent of public libraries provide their community's only free public access to computers and the Internet. Not surprisingly then -- due to the economic hardship -- more people are using libraries.A study sponsored by the Bill & Melinda Gates Foundation and published by the Institute of Museum and Library Services last year found that 69 percent of Americans 14 years of age or older visited a public library in 2009.
Regardless of its exact nature, technology will play an increasing role in shaping our future libraries. For centuries, the book publishing industry has worked closely with and supported libraries, and they have done so without influencing the freedom of the institution. It is now time for the technology industry to step up and play a similar role.
Here is how technologists can, and should, help support libraries:
- Offer training and support -- free of charge -- to libraries for items such as digital reading devices, tablets and other media devices. Helping technology companies as well as libraries, this will serve to educate the general public in the long run.
- Provide special access to materials - something publishers have been doing for years. While technologists can't always control pricing, we can offer special programs to help educate the public and broaden access.
- Open lines of communication, offering libraries insight into how technologists see the market evolving. This will help library administrators make informed decisions regarding the future of their institutions.
Free means Free
Digital reading has taken off over the past three years in ways that no one would have imagined a decade ago. Earlier this year, the Book Industry Study Group reported that eBook sales rose from 1.5% of all book sales in Q1 2009 to 5% in Q1 2010. This is a wonderful thing in many respects - digital reading makes it easier to publish and distribute materials than ever before. But, the race is also on to lock down the market on ebooks by locking consumers into a specific platform, and this is the equivalent of curbing access.
Sony's Perspective
At Sony, we believe there is a place for public/private partnerships. That's why we're so excited to be working closely with libraries and librarians across the country as part of our Reader Library Program. While there are several different views on the future of libraries, we believe that digital reading will be at the core of libraries, regardless of how they grow and evolve.

Sony's Reader Library Program is designed to help libraries overcome the challenges of adopting eBooks and educating their constituencies on how to borrow, read and make the most of digital reading content. eBooks, like traditional paper books, will play an important role in our civic and cultural life, but only if they are made broadly available and people understand how to access and use them. Sony's Reader Library Program includes four main components:
- A training program for library staff developed by Sony. This training includes in-person workshops, video training and additional materials available on the web, covering digital reading formats, an overview of sources for digital materials, and training on Sony's Reader digital reading devices.
- Sony's Reader digital reading devices for use by library staff.
- Educational materials to provide readers some background on digital reading devices.
- Bi-annual update sessions designed to keep libraries and their staff current with the latest developments in digital reading content, format and devices.
We believe it is extremely important to support public library systems as they expand their digital offerings and our initiative will provide these professionals with training and additional resources that will enable them to inform their patrons on how to benefit from their growing eBook collections. With this type of support, we believe they'll not only survive, but thrive in continuing to provide free access to knowledge in the digital age.

Cell phones: precautionary approach needed
Though no adverse health effects have been established for mobile phone use, excessive use by children should be discouraged
In December 2010, Matt Parker, a British mathematician, tabulated the number of mobile phone masts in each county across the United Kingdom and then matched it with the number of live births in the same counties. He discovered that the correlation was so strong that in areas above normal numbers of mobile phones, he could predict how many more births above the national average occurred.
Parker concluded that for every additional mobile phone base station in an area, the number of births goes up by an average of 17.6 babies!
In reality, mobile phone masts have absolutely no bearing on the number of births. Masts do not make people more fertile. There is no causal link between the masts and the births despite the strong correlation.
The number of mobile phone transmitters and the number of live births are linked to a third factor, the local population size. As the population of an area goes up, so do both the number of mobile phone users and the number of people giving birth. Instinctively we tend to assume that correlation means that one factor causes the other!
Parker published a phoney press release highlighting his finding to see whether media outlets would jump to the incorrect conclusion that mobile phone radiation causes pregnancies. Main-stream media ignored the hoax release after checking out the facts. Some readers reacted differently.
“There were the expected people who clearly did not actually read what I wrote before seeing the headline and getting excited about this apparent scare story, but there were also seemingly endless comments from people who understood my correlation-causality project but could not help putting forward a possible causal link anyway” Parker said.
His headline to The Guardian article “Mobile phone radiation linked to people jumping to conclusions” was apt.
Over the years, there has been differing news on the risks of radiation from mobile phones. A WHO booklet published in May 2010, stated that no adverse health effects have been established for mobile phone use. Studies are ongoing to assess potential long-term effects. WHO noted that there is an increased risk of road traffic injuries when drivers use mobile phones (either handheld or "hands-free") while driving.
According to HPA (HPA, May 17,2010), there are thousands of published scientific papers covering research about the effects of various types of radio waves on cells, tissues, animals and people. HPA's views derived from them were identical to those of the WHO.
Widespread use
Given the uncertainties and the widespread use of mobile phone technology, HPA recommended a precautionary approach.
This included a recommendation that excessive use of mobile phones by children should be discouraged. Every country must enforce international guidelines on mobile phone technology.
Some possible effect
In 2009, members of the ICNIRP (International Commission on Non Ionizing Radiation Protection; most countries have accepted the Commission's guidelines) Standing Committee on Biology noted that there is some evidence of an effect of exposure to a Global System for Mobile Telecommunication (GSM)-type signal on the spontaneous electroencephalogram (EEG).
This may be of little functional significance since they did not observe significant effects on cognitive performance in adults. They noted that the effect is small and exposure seems to improve performance.
The authors noted that symptoms such as headaches and migraine had been attributed to various radiofrequency sources both at home and at work.
“However, in provocation studies a causal relation between EMF exposure and symptoms has never been demonstrated. Psychological factors such as the conscious expectation of effect may play an important role in this condition” (HPA, May 2010).
There were suggestions that radiofrequency energy may cause brain tumours such as glioma
In May 2010, the Interphone Study the largest of its kind in which thirteen countries including UK, Sweden, France and Germany collaborated concluded that overall, no increase in risk of brain tumours was observed with the use of mobile phones.
“There were suggestions of an increased risk of glioma at the highest exposure levels, but biases and error prevent a causal interpretation. The possible effects of long-term heavy use of mobile phones require further investigation"(International J. Epidemiology, 2010)
Over all, we need not lose sleep on the potential harm of mobile phone radiation. Let us minimize mobile phone use as a precautionary measure and discourage children from using them.

Positive posture
Sitting long hours before the computer can give you health and posture problems.
Are you an Internet addict? Or do you spend lots of time in front of the computer? Well then, this is for you.
In this era of increased knowledge thanks to the online sources, the effect of long hours on the Internet results in sluggishness, lack of concentration and tiredness. Sheela, a mother of two, says, “though it is not possible to curb the use of Internet completely, giving children new books, introducing them to outdoor activities would certainly help.”
Agrees children's specialist, Dr. Bhaskar, “Children who sit for long hours put on weight.” The way children sit, the number of hours that they sit in front of the monitor, is to be carefully scrutinised. Frequent breaks are a must, even if it is reaching for a glass of water from the kitchen.
Naveen D., who has pursued his masters in ergonomics suggests, “Buying a chair which will last 5-10 years is a bad practice, as children will grow and each time adequate attention needs to be paid.”
Right chair
Ergonomics has a lot to offer in terms of the right body posture. While sitting on the chair in front of the computer system push your hips as far back as it can go in the chair. Sitting such that the entire chair is occupied is a good practice.
Once seated, do not let your feet dangle in the air, adjust the seat height so your feet are flat on the floor and your knees equal to, or slightly lower than, your hips. He further adds, “childhood is also the time when most eye conditions (such as nearsightedness) tend to develop, so if you find yourself leaning in front to peer at the monitor, be sure to have the eyes checked.
Consider using a good quality, glass anti-glare screen, which can help you avoid squinting and eye strain.”

Recipes for a Day of Eating Like Leo
Breakfast
Cinnamon Steel-Cut Oats
[5 ingredients]
serves 2
Breakfast can be difficult if you’re addicted to cereal and milk or yoghurt. These oats are a life saver. They take a little while to cook but are well worth the effort for their creamy soul-satisfying comfort. The cinnamon really brings a big flavour hit and the flax seeds provide one of the best vegetarian sources of omega-3 fatty acids.
I could eat these oats every day, just varying the accompaniments to keep it interesting. I’ve used frozen blueberries and brazil nuts here. You could substitute in any nut, seed, berry or even bananas, raisins or other fruit.
- 1 cup steel-cut oats 1 tablespoon flax seeds 1/2 teaspoon cinnamon 1 handful brazil nuts 1 handful blueberries
2. Cook over a medium-high heat, stirring occasionally for about 10 minutes, or until the oats have thickened.
3. Divide between 2 bowls and top with brazil nuts and berries.
Lunch
Big-Ass Avocado & Almond Salad
[5 ingredients]
serves 1
If you prefer to wash your own leaves, please do so. Look for a mix containing kale and spinach if you can, although pretty much all salad greens will be lovely.
Feel free to play around with the accompaniments. Different nuts are a great place to start but you could also add other vegetables such as halved cherry tomatoes, shaved raw fennel or zucchini.
Lemon or lime juice can make a good alternative to balsamic vinegar in the dressing.
- 1 tablespoon aged balsamic vinegar 1 bag prewashed salad leaves 1 small avocado 1 handful raw almonds
2. Toss leaves in the dressing to coat them evenly.
3. Halve avocado lengthwise and remove the stone. Using a spoon, scoop out the flesh into little round chunks and arrange over your salad.
4. Scatter with the almonds and dig in!
Dinner
Vegan Chilli
[5 ingredients]
serves 5 – 6
Loosely based on Leo’s 3 Bean Vegan Chilli, I’ve simplified the recipe to fit my own 5 ingredients philosophy. Feel free to play around with the types of beans you use. They’re all good. A can of lentils or two would be right at home here as well.
The longer you simmer the chilli, the better your flavours will come together. It’s fine after 15 minutes but 30 minutes or a little longer is preferred. It’s also one of those things that improves with age, so don’t be afraid to make a big batch and eat it over a few days. Great for lunches too.
Please use the chilli in the recipe as a guide. If you like it fiery, by all means add more, but remember it’s hard to undo something that’s too hot!
I like to serve in bowls with a green salad. Some wholegrain bread or brown rice would also work well.
- 2 brown onions, peeled & chopped 2 cans red kidney beans (14oz / 400g each), drained 2 cans black beans (14oz / 400g each), drained 3 cans tomatoes (14oz / 400g each), drained 2 – 4 teaspoons chilli powder
2. Add onion and cook, covered, stirring occasionally for about 10 minutes or until the onion is soft and golden.
3. Coarsely chop one can of red kidney beans and add to the onion.
4. Add remaining whole beans, tomato and chilli powder and bring to a simmer.
5. Cook over a medium high heat, stirring every now and then for 15 minutes or longer if you have the time.
6. Taste and season generously with salt, pepper and possibly a little more chili.

A sneeze can contaminate surroundings for hours
A single sneeze infests a room with deadly bugs and the contamination can last for hours.
Microscopic droplets sneezed or coughed out float around the air in large enough concentrations to spread disease, researchers say.
A sneeze typically contains as many as 40,000 droplets, some of which leave the body at more than 160 kmph.
Breathing in airborne specks of virus found in a typical office, plane or train could infect a person after just one hour, the Journal of the Royal Society Interface reports.
It also highlights why so many holidaymakers pick up coughs, colds and sniffles at the start of their trip, following a flight, according to the Daily Mail.
Flu passes from person to person through direct physical contact, or when someone sneezes or coughs.
U.S. researchers collected samples of air from the waiting room of a healthcare clinic, three rooms in a nursery and three cross-country flights. Half the samples contained small droplets containing the flu virus.
Scientists found that a typical cubic metre of air contained an average of 16,000 particles of flu virus. Most were less than 2.5 thousandths of a millimetre across, which remain suspended in the air for hours on end.
“Given these concentrations, the amount of viruses a person would inhale over one hour would be adequate to induce infection,” said Linsey Marr, who led the study at Virginia Tech.
“The virus-laden aerosols are small enough that the smallest ones can remain suspended for days,” she added.

Milk everyday ‘keeps cancer at bay’
Children, please note -- drinking milk everyday can keep bowel cancer at bay, says a new study.
Researchers in New Zealand have carried out the study and found that children who drink half-a-pint of milk daily are 40 per cent less likely to suffer bowel cancer as adults, the ‘American Journal of Epidemiology’ reported.
According to them, milk has a powerful protective effect against cancer and the key to its anti-cancer effects
lies in daily consumption over long periods.
“Our results suggest daily consumption of milk in childhood may reduce bowel cancer incidence, possibly by the action of calcium,” the ‘Sunday Express’ quoted Prof Brian Cox, who led the study, as saying.
In fact, in their study, involving a group of students, the researchers discovered that the subjects were 40 per cent less likely to suffer a tumour later in life if they had milk every day for six years or more.
The findings support previous evidence from the World Cancer Research Fund that milk protects against cancer.
Campaigners said the research highlighted the benefits of school milk.
Dr Judith Bryans, director of the Dairy Council, said: “School milk is hugely important because it ensures children have an adequate supply of nutrients. One glass of milk has the same amount of calcium as a kilogramme of spinach.”
However, a spokeswoman for Cancer Research UK said: “The best ways to reduce bowel cancer risk are to keep a healthy weight, drink less alcohol and be physically active.”

Injustice of Abortion
My fellow pro-life friends, we must fight against this crime. It may be hard to over rule the justice system, but we could fight to stop the funding for planned parenthood and other women's clinics out there. Once the funding is stopped, then they could not function.
Are you a passive Pro-life or an Active Pro-Life? Well, after seeing this video you must decide whether to keep your mouth shut or do something about this.
(WARNING: GRAPHICAL) Click the below link ONLY if you are prepared to Cry and challenged enough to STOP millions of BRUTAL MURDERS happening in USA and rest of the world. Abortion MUST BE STOPPED and Everyone MUST be educated on Abortion what really is and then choose “should I be passive or active”.

Don't save passwords on your browser
Never store unencrypted passwords on a computer’s browser. Doing so makes it too easy for hackers to access the data with tools like Trojans and then access private accounts, warns German computer magazine C’t.
The magazine recommends that people who insist on storing passwords on a browser at least use some kind of master password, which means that all stored access data is safely encrypted. However, that option is only available with Firefox and Opera.
To access this function in Mozilla’s Firefox, users must go to Extras/Settings/Security and then click the option to “use a master password.” Opera automatically asks the first time a password is stored if users wouldn’t rather set up a master password.
Many computer users do not adequately protect their accounts. The most popular passwords include “123456” or “Password” — both of which are incredibly easy for cybercriminals to figure out. Worse, one password often tends to provide access to multiple accounts.
C’t advises using passwords with at least eight characters and to make each password unique to a particular website.

How to find your stolen laptop
This peice of info might be useful to all laptop users...
These days it has become easy to track a stolen laptop, courtesy, large number of laptop-recovery software. Most of these software automatically transmits the location of the device back to a central server.
However, according to several experts, these theft-tracking software also make a user's laptop more vulnerable to spying.
To tackle this, researchers at the University of Washington and the University of California, San Diego, have developed a free software that records location information in such a way that only a legitimate user can get access to it.
Most of the laptop-tracking software periodically update a database with data related to the laptop's physical location, such as its current IP address and local network topology. While this data helps the security agencies to track the laptop they also help monitor the user's movement if the data is compromised.
Called Adeona, it uses several cryptographic techniques to keep location information secure. Like the other software, the laptop running the software still sends location information to a central database, just that the data is encrypted so that it cannot be read without a private cryptographic key.
Adeona works with Windows, Macintosh and Linux. For Mac users, it has an add-on that regularly takes photographs using the laptop's built-in camera, to provide further evidence to the police.
The researchers are currently working on a version of Adeona for the iPhone.

End your day peacefully for a good night’s sleep
It’s easiest to get a healthy and relaxing night of sleep if you end your day peacefully.
“Always avoid strenuous activities, stress, frustration or excitement just before bedtime,” says Heike Hofmann of the German Academy for Prevention and Health Management/BSA Academy in the western German city of Saarbruecken.
She recommends paying attention to one’s diet, and having smaller and lighter meals just before bedtime. It’s also a good idea to avoid alcohol and caffeine in the evening.
The layout of one’s bedroom also plays a role. It should be set up to promote sleep, says the psychologist and lecturer. That means the bed should only be used for sleeping; not smoking, eating, drinking or watching TV.
“Ban everything from your bedroom that disturbs you, like a ticking clock or things that remind you of your job or everyday stress,” she says.
Additionally, one should only go to bed when one is really tired.
“And try to get as regular a sleep-wake rhythm as possible.”
