Several hundred bees in rural Pennsylvania and rural New York are sporting tiny QR codes on their backs. More than the latest in apiarian fashion, the little tags serve a scientific purpose: tracking when bees go in and out of their hives to better understand how long honey bees spend foraging for food outside of…

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion through enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA…

A new study led by the University of Oxford has used a modeling approach to show that it is unlikely that plants would evolve to warn other plants of impending attack. Instead of using their communication networks to transmit warning signals, the findings suggest it is more likely that plants “eavesdrop” on their neighbors. The…

Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we ‘derive’ it in a purely theoretical fashion? Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards…
