Lovely SEM image of pseudostratified ciliated columnar epithelium. This tissue lines the trachea and upper respiratory tract, and is responsible for sweeping debris out of your lungs, up your wind pipe, and into the back of your throat where you’ll either a) cough it out or b) swallow it. People who are smokers are constantly killing off these cells, which is why smokers are so prone to lung infections; they lack the ciliated cells to keep crap out of their lungs.

Deadly man-made strain of bird flu virus: Should they publish?

The scientist whose team created this virus is Ron Fouchier of Erasmus Medical Center. He told Science Insider that the genetically modified bird flu virus strain is “probably one of the most dangerous viruses you can make.” Fouchier’s work is now part of a debate over what is called dual-use research. That is research with the potential to benefit humanity, or harm it, should the research details or manufactured materials fall into the hands of bioterrorists.
