Autonomous weed control via smart robots

Soybean fields are becoming increasingly infested with a glyphosate-resistant weed called ‘palmer amaranth.’ One pesticide currently used for controlling it is ‘Dicamba,’ but it has devastating effects on adjacent areas, because it tends to drift when sprayed during windy conditions. Researchers report that they have now developed a drift-free, weed-specific applicator, which will pave the way for autonomous weed control with smart robots.

New structural phase transition may broaden the applicability of photo-responsive solids

Scientists discovered a new type of structural phase transition of an organic crystal called the photo-triggered phase transition. Under this phenomenon, the crystal, which exhibits a thermal phase transition that is reversible by heating and cooling, transforms to the identical phase upon light irradiation at temperatures lower than the thermal transition temperature. The photo-triggered phase transition may extend functions of photo-responsive solid materials in the future.
