Yale study shows why cigarette smoke makes flu, other viral infections worse
A new study by researchers at Yale School of Medicine could explain why the cold and flu virus symptoms that are often mild and transient in non-smokers can seriously sicken smokers. Published in the Journal of Clinical Investigation, the study also identified the mechanism by which viruses and cigarette smoke interact to increase lung inflammation and damage.

Make your own microfluidic device with new kit from U-M
A type of device called a “lab-on-a-chip” could bring a new generation of instant home tests for illnesses, food contaminants and toxic gases. But today these portable, efficient tools are often stuck in the lab themselves. Specifically, in the labs of researchers who know how to make them from scratch.

‘Burns believes microfluidics will go the way of computers, smaller and more personal as technology advances.

‘”Thirty or 40 years ago, computing was done on large-scale systems. Now everyone has many computers, on their person, in their house…. It’s my vision that in another few decades, you’ll see this trend in microfluidics,” Burns said. “You’ll be analyzing chicken to see if it has salmonella. You’ll be analyzing yourself to see if you have influenza or analyzing the air to see if it has noxious elements in it.”‘

‘A paper on the new system called “Microfluidic assembly blocks” will be published in Lab on a Chip. It is available early online at: http://www.rsc.org/Publishing/Journals/LC/article.asp?doi=b805137b’
