This summer, Naegleria fowleri is the new great white shark. A freshwater-dwelling amoeba that can invade the human nervous system and, on rare occasions, kill, N. fowleri (or, as they are more commonly known, "brain-eating amoebas") have apparently succeeded in making everybody a little more afraid to get in the water.
But is the fear justified?
Most of you can probably guess that the answer is, "No." But why, specifically? Julia Diebol at the Risk Science Blog does a nice job of clearly laying out why these amoeba are so attention-grabbing, and why they shouldn't keep you up at night.
Shorter version: Just being in amoeba-infested waters doesn't mean you'll get one up your nose. Or, at least, it doesn't mean that you'll die. The amoebas have only killed 129 Americans since 1937. That's more than I'd previously thought, but not remotely enough to justify a panic. Especially given that the risk of infection doesn't seem to be increasing.
Granted, there's a lot we don't know about N. fowleri. Key question: Why can hundreds of people swim safely in lake water that leads to amoeba infestation and death for one person? Nobody knows yet what factors make some people susceptible and others, apparently, not. But we do know this: On your list of things to worry about, brain-eating amoebas should be near the bottom.
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]

3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
