Brain-Eating Amoeba Scoffs At Chlorine In Water Pipes

Slashdot -

An anonymous reader writes: The Naegleria fowleri amoeba typically feeds on bacteria in water and soil. Human digestive systems have no problem killing it, but inhaling water that carries the amoeba gives it the opportunity to work its way into the brain after it sneaks through the nasal mucus. It happens rarely, but 97% of people whose brains start swelling because of this amoeba end up dying. Like most microorganisms, N. fowleri can be neutralized with concentrated chlorine. However, the systems we use to deliver tap water aren't so clean. Researchers found that N. fowleri can easily survive for 24 hours when it's mixed with the types of biofilm that tend to reside in water pipes. Increasing chlorine levels isn't a good option, since its reaction with these biofilms can generate carcinogens.

Earth Home To 3 Trillion Trees, Half As Many As When Human Civilization Arose

Slashdot -

sciencehabit writes: Earth today supports more than 3 trillion trees—eight times as many as we thought a decade ago. But that number is rapidly shrinking, according to a global tree survey released today (abstract). We are losing 15 billion trees a year to toilet paper, timber, farmland expansion, and other human needs. So even though the total count is large, the decline is "a cause for concern," says Tom Spies, a forest ecologist with the U.S. Forest Service in Corvallis, Oregon, who was not involved with the work.
