Breath

Measuring the level of magnetism of tree leaves could be a powerful tool to monitor the air quality of streets. A new study has shown that leaves along bus routes were up to ten times more magnetic than leaves on quieter streets. The magnetism comes from tiny particles of pollution, such as iron oxides from diesel exhaust, that float through the air and either stick to the leaves, or grow right into them.  Read More

Out of sight might mean out of mind, but it doesn’t necessarily mean out of danger, particularly in the case of small airborne particles. Such particles can severely affect your health, with effects ranging from asthma and bronchitis to lung cancer. If you’re worried about the possible presence of airborne particles in your home researchers at Tel Aviv University (TAU) have developed a sensor called ‘Dust Alert’ that could confirm your suspicions or better yet, set your mind at ease.  Read More

Gold nanoparticles are being used by researchers in Israel in a new type of breath test to detect lung cancer in patients. Breath particulate analysis isn’t new but the scientists say this is the first time a technique has been used without the need to pre-treat the exhaled breath, delivering a quicker and less expensive diagnosis. Early detection can result in faster treatment and hopefully save lives. Around 25 percent of all cancer-related deaths are lung cancer sufferers, with estimates put at around 1.3 million people dying from the disease each year.  Read More
