Infusing foods with smoke can impart delicious nuanced flavors, but could also come with an unwelcome side of carcinogens.

The closer the contact someone has with individuals with tuberculosis, the more likely they are to become infected with the pathogen. However, only about five to ten percent of people infected with the pathogen go on to develop the disease. An international team of researchers, including scientists from the Max Planck Institute for Infection Biology in Berlin, has now developed a simple blood test to enable them to estimate the risk of developing active tuberculosis. Using the new test, the researchers can predict who is likely to come down with the disease.
