Field #Pennycress, a plant in the Brassica family related to #mustards and #cabbages, is usually considered a #weed. But one feature made it less of a wallflower: its very high #OilContent, about 50% higher than that of a #soybean.

Three non-conspiracies in one #photograph during today’s #sunset. There is a #WaxingCrescent #NewMoon, to which humans have been in my lifetime. The #contrail that a passing #aeroplane is illuminated by the setting #Sun and is made up of water droplets condenses out of hot exhaust #gases of the #JetEngines.
