Sneezing is even more disgusting with high-speed cameras
New, super-gross research out of MIT is shedding new insights into what happens when we sneeze. Researchers from the university used high-speed photography to record 100 healthy volunteers right at the moment they sneezed. Turns out, the sticky fluid flies out of our mouths, not as a spray, but as a sheet. Ew. Then it pops, like a balloon, and the snotty filaments remaining then in turn break up into the fine mist we're familiar with. Double ew.
Carbon nanotubes used to more easily detect cancer cells, HIV
Cancer's not slowing its march to ruining as many lives as it possibly can, so it's always pleasing to hear of any new developments that act as hurdles. The latest in the world of disease-prevention comes from Harvard University, where researches have created a dime-sized carbon nanotube forest (read: lots of nanotubes, like those shown above) that can be used to trap cancer cells when blood passes through. A few years back, Mehmet Toner, a biomedical engineering professor at Harvard, created a device similar to the nano-forest that was less effective because silicon was used instead of carbon tubes. Today, Toner has teamed up with Brian Wardle, associate professor of aeronautics and astronautics at MIT, who together have redesigned the original microfluid device to work eight times more efficiently than its predecessor. The carbon nanotubes make diagnosis a fair bit simpler, largely because of the antibodies attached to them that help trap cancer cells as they pass through -- something that's being tailored to work with HIV as well. Things are starting to look moderately promising for cancer-stricken individuals, as hospitals have already began using the original device to detect malignant cells and ultimately prevent them from spreading -- here's hoping it's qualified for mass adoption sooner rather than later.
Scientists attempt to predict flu spread, give ZigBee radios to 700 high school students
This is the Crossbow TelosB wireless remote platform, and it did an important job for science in January of last year -- it monitored the close proximity interactions among 788 students and staff at one US high school to track a virtual flu. After collecting over 762,000 sneeze-worthy anecdotes among the module-toting teachers and teens, Stanford researchers ran 788,000 simulations charting the path the virus might take and methods the school might try to keep it in line. Sadly, the scientists didn't manage to come up with any easy answers, as virtual vaccination seemed to work equally well (or poorly) no matter who got the drugs, but that if only we could actually monitor individuals in real life as easily as in a study, prevention would be much easier. But who will bell the cat, when it's so much less political to ionize?
