Create a disease to kill off humanity with these iOS games

Pandemic, the first game in this duo, was released for Web browsers back in 2007. The object of the game was to infect a person with a disease you created, then manage the outbreak and evolve the disease to create the most worldwide damage. I agree that the game's subject is morbid, but the huge popularity of Pandemic showed that the actual content doesn't make it any less addictive.

At the beginning of last month, Pandemic 2.5 was released for iOS and quickly shot up the App Store's most-popular lists probably based on the Flash version's popularity. But at the end of May, a very similar game was released that might even be better than the original.

In testing these games, I infected most of the world with my various diseases, but never had one that destroyed all of humankind. Those who have played Pandemic in the past might guess that Madagascar was my downfall (it's a joke among Web gamers that Madagascar is always the one to close its shipyards at the first whiff of danger), but it was Iceland that put a stop to the deadly Parkerism.… Read more

Portable device to detect pathogens in 30 minutes

Engineers at Cornell are building a handheld pathogen detector that will help health care workers around the world test for pathogens such as tuberculosis, gonorrhea, and HIV and get results in as little as 30 minutes, instead of waiting days.

Dan Luo, professor of biological and environmental engineering, has been using synthetic DNA to amplify tiny samples of pathogen DNA, RNA, or proteins. Because of $25 million in funding from the Bill & Melinda Gates Foundation's Grand Challenge to 12 teams developing point-of-care diagnostics, Luo will be combining forces with Edwin Kan, a Cornell professor of electrical and computer engineering, who has built a computer chip that can respond quickly to those amplified samples.

The engineers describe their novel device as something akin to a molecular-level Lego builder.… Read more

Showers may be far dirtier than we think

As if we didn't already have enough germs and toxins to deal with in our home environments (the lead in our paint; flame retardants in our furniture; indoor air quality and even the resulting air purifiers; to name a few), we now get to fret over another perpetrator: the showerhead.

Researchers at the University of Colorado at Boulder have just published a study in the Proceedings of the National Academy of Sciences finding that about 30 percent of the showerheads in nine cities (including New York, Chicago, and Denver) carry "significant" levels of Mycobacterium avium, a pathogen … Read more
