Scientists accidentally produce an enzyme that devours plastic
There are research teams around the world dedicated to finding a remedy for the growing plastic pollution crisis, but now it seems that one group of scientists have found a feasible answer -- and they stumbled upon it by accident. Researchers studying a newly-discovered bacterium found that with a few tweaks, the bug can be turned into a mutant enzyme that starts eating plastic in a matter of days, compared to the centuries it takes for plastic to break down in the ocean.
Scientists take detailed pictures of the smallest known life forms
Just how small can life get? Almost unbelievably small, if you ask a team of Berkeley Lab researchers. They've taken the first detailed electron microscope pictures of the tiniest bacteria known to date -- at a typical 0.009 cubic microns in volume, you could fit 150 of them in an already miniscule e. coli cell. Scientists had to catch the hard-to-spot microbes by using a new portable cryo plunger, which flash-froze groundwater to near absolute zero (about -458F) to keep the cells intact while they were in transit.
Online gamers solve microbiology puzzle, contribute to anti-HIV solutions
Hey guys, look! Gamers are good for something! After struggling for some time to successfully map the structure of M-PMV, "a protein involved in a virus that causes a form of simian AIDS," scientists decided to hand the task off into more capable hands. Unfortunately, the only hands they could find were those of online gamers. Always willing to rise to a challenge, however, the gamers didn't disappoint. Through the use of a program called Foldit, which takes the mapping of molecular structures and transforms them into a sort of puzzle game, gamers (particularly a group calling themselves the Foldit Contenders) were able to successfully map the protein. Scientists hope that the crowdsourced solution can be used to design new drugs, such as treatments for HIV. Way to prove our worth to society, folks. You've made us proud.
