Do Laser printers cause harm to your health?
According to the recent study published in the online issue of American Chemical Society’s Environmental Science & Technology Journal,some of the Laser printers could release tiny particles of toner-like material into the air and could pose a long term health hazard to people when these are inhaled.
The report which was based on the research conducted at the Queensland University of Technology in Brisbane study who studied the printers used in our home and office found that some of these printers released particles from the toner-an ultra thiner powder used instead of ink.
This study investigated particle number and PM2.5 emissions from printers using the TSI SMPS, TSI CPC 3022, and 3025A TSI P-Trak and DustTrak.The monitoring of particle characteristics in a large open-plan office showed that particles generated by printers can significantly (p = 0.01) affect the submicrometer particle number concentration levels in the office.These released particles were comparable to emissions released from cigarette smoking.
This could mean that you could end up with the same lung as a passive smoker does?
Think about it.

You like your morning cup of coffee,but did you know that it could be beneficial to your health,while now French researchers compared women aged 65 and older who drank more than three cups of coffee per day with those who drank one cup or less per day.and they found that Those who drank more caffeine showed less decline in memory tests over a four year period.The study, published in the journal Neurology, raises the possibility that caffeine may even protect against the development of dementia.
Rebecca Wood, chief executive of the Alzheimer’s Research Trust, said that with no cure for Alzheimer’s disease yet available, research into possible protective factors was important, particularly as the disease is expected to become more common.She said: “This study does not suggest that caffeine actually lowers rates of dementia in women, but since memory seems improved, it may be that it is slowing it down.
So coffee could be beneficial to you after all.Only time will tell.

Technologies usually play an important role in material world,but now they find application in our spiritual world also.
Can we now analyze,measure happiness with technology more so with nanotechnology?
Yes with the reasearch work of Yoshinobu Baba, a professor of chemistry at Nagoya University and a director for nanobiotechnology research at the National Institute of Advanced Industrial Science and Technology in Japan.His work is on how Nanobiotechnology could be used as a measure of happiness, stress levels and health.
He says that we can measure the stages of cancer or diabetes, since genomic research tells us which genes are related to which diseases. But we need to analyse proteomics and glycomics in more detail. The next stage is to measure the function of the brain, looking at happiness and stress.

It is estimated that more than 22 million people are at risk of sudden heart failure at any one time around the world, experts say. But timely care and prompt treatment can save many people’s lives if their heart fails.
The trick is getting medical help quickly enough.
That’s where the new device comes in. Reporting in the International Journal of Electronic Healthcare, Thulasi Bai and S.K. Srivatsa from Sathyabama University in Tamil Nadu, India, have developed a wearable cardiac “telemedicine” system for post-cardiac patients.
