A 10-pound rat wouldn’t normally evoke feelings of appreciation, but perhaps it should — apparently it can save lives by sniffing out tuberculosis. Rat disease recognition is much more accurate than microscopes, researchers say.
We're going to try to avoid using the adjective "cool" to describe this neat little biomedical trick: researchers at the University of Victoria in Canada have swapped a few essential genes from Arctic bacteria into their counterpart mammalian pathogens, creating strains that are harmful enough to provoke an immune response but that can't survive in warmer parts of the body where they might do serious damage. The method could lead to a new generation of temperature sensitive vaccines that – try as they might – simply can't make you sick.
Existing lab-on-a-chip designs can put the power of testing in the palm of your hand, but an upcoming model may represent the cheapest and most colorful one yet. A Harvard University chemist has created a prototype "chip" technology out of paper that could help diagnose HIV, malaria, tuberculosis and other diseases for just a penny each time, according to CNN.

In 2007, David Edwards, a biomedical engineer at Harvard University, gave his students a project: Develop a way to inhale food, rather than chewing and swallowing it. “They took a whiff of everything from pepper to carrots and coughed a lot,” Edwards says. Last fall, he introduced Le Whif, a lipstick-size inhaler that drops a delicious, one-calorie chocolate taste on your tongue.
The number of multidrug-resistant tuberculosis cases may be rising even faster than we realize

The World Heath Organization has released the results of a four-year study of patients in 81 countries which shows that rates of multidrug-resistant tuberculosis (MDR-TB) are at their highest levels yet recorded. Extremely drug-resistant tuberculosis, which is nearly untreatable, has appeared in 45 of those countries. At face value, this sounds like bad news, but the true global reality may be even worse. Only six nations in Africa, where tuberculosis has the highest incidence, were able to provide any data.
