    Published today in Science Advances, the findings explain that manta rays filter zooplankton, mesoplankton and microcrustaceans with an apparatus different from anything previously seen in any biological or industrial system. "The most common type of filter is a sieve filter, where a particle-containing fluid is passed through a membrane with pores smaller than the particles," said study co-author Jim Strother, assistant professor of integrative biology in the OSU College of Science. Sieve filters include everything from a kitchen colander that strains pasta to membrane filters that produce ultrapure water. Other filter mechanisms are hydrosol filtration, such as the fiber filters...
  • You Swallow These Invisible Shrimp With Every Gulp of NYC Tap Water [Violates Kosher Laws?]

    New York's water is delicious—and filled with tiny crustaceans called "copepods". (Making it possibly not kosher.) H&E stain the water and put it under a microscope and you'll find these little guys. Crunchy closeup after the jump.Delicious!(And completely harmless. Copepods are even known to eat mosquito larvae, so don't think of them as invisible shrimp that are caught in your teeth—think of them as invisible shrimp who make NYC tap water taste fantastic. Like fantastic, quenching shrimp juice.)[Reddit]

    Keeping an army provisioned in the desert is a ballet of logistics, particularly when it comes to supplying two vital liquids: diesel fuel and water. Now, using technologies developed for the space program, the U.S. Army is conducting an experiment that could convert the exhaust pipes of military vehicles into water fountains. Later this month, United Technologies Corp.'s Hamilton Sundstrand unit will deliver two military Humvees to the Army for three months of testing at the Aberdeen Proving Ground outside Baltimore. Built into each vehicle's truck bed is a complex system that can recover water from engine exhaust, purifying as...
