Electronic nose that sniffs obstruction in breathing during sleep!
Obstructive sleep apnea (dangerous pauses in breathing) could be diagnosed by tweaking an electronic nose used in detecting molecules in a patient’s breath. The gold standard used to identify sleep apnea is an overnight sleep test, a technically demanding, time-consuming and cost-intensive system.
Electronic noses have shown to distinguish between a number of diseases. They do this by analysing the pattern of volatile organic compounds in breath samples. This is the first study that has assessed whether the electronic nose could be used to confirm the presence of sleep apnea, the European Respiratory Journal reports. Researchers analysed the breath of 40 sleep apnea patients and 20 healthy patients who did not suffer from this disorder, according to a Marburg statement.
‘The electronic nose could be useful in two ways: First, it can rule out the disease in a low prevalence population. Second, in a population with a high risk of sleep apnea, the device could be used to help decide who would need to undergo an overnight sleep examination,’ Timm Greulich, from the Marburg Hospital in Germany, who led the study, said.
‘Following these results, we foresee that the use of the electronic nose could reduce costs by more appropriately selecting patients who require the sleep examination,’ Greulich said.
The study also aimed at assessing whether the electronic nose could detect the effects of the standard treatment for sleep apnea, continuous positive airway pressure (CPAP). The results found that the electronic nose could effectively diagnose sleep apnea. The statistical analysis showed that it was detected with a sensitivity of 93 percent

Is microwave cooking bad for you?



More specifically, is radiation from a microwave harmful?

It is true that microwaves work on radiation, but hold on. The story continues... radiation is energy that travels in waves. But there are different waves - radio waves, X-ray and energy waves and micro wave is weaker than gamma rays. So don't worry about turning into mutants.
Conclusion: Microwave cooking is not harmful as long as the door is closed. Thankfully no microwave allows use unless the door is firmly secure.

Does microwave cooking and heating affect food?
Microwave cooking and heating does not change the components of your food, it only heats the food. There is no evidence of toxin formation in food or carcinogens. If you over cook your food, then you are changing the components of the nutrients in your food. Over cooking on a grill, in the oven or micro wave - irrespective of the heat's source - destroys the nutrients.

Conclusion: Microwaves do not change the nutrients of the food.
Radiation leaks from the microwave
Microwave leaks are possible if the door is damaged and cannot be shut properly. There are a few steps to ensure that your cooking machine does not leak of radiation.

Do not fidget with the door
Check for door damage regularly
Clean the interior of the microwave frequently
There are no serious microwave health risks unless it's carelessness on your part. Be wise: Use the right containers, avoid cling film from touching the food, and maintain the microwave regularly.
