Fermilab is looking for volunteers to help with its annual prairie seed harvest. Two harvest events are planned, on Saturday, Oct. 5 and Saturday, Nov. 2, beginning at 10 a.m. Fermilab’s site hosts 1,000 acres of restored native prairie land, and each year community members pitch in to help collect seeds from those native plants.

On Aug. 31, the Dark Energy Survey (DES) officially began. Scientists on the survey team will systematically map one-eighth of the sky (5000 square degrees) in unprecedented detail. The start of the survey is the culmination of 10 years of planning, building and testing by scientists from 25 institutions in six countries.
