ResearchBlogging editor's selections: bulletproof T-shirts, spinning light, beauty for birds, and flocking folks

Apr 19 2010 Published by under General science, Science news

  • Bulletproof T-shirts? Who'da thought it was possible?  Christie over at Observations of a Nerd discusses recent successful attempts to "bulletproof" T-shirts!
  • Measuring the Angular Momentum of Light. Light can carry angular momentum, and therefore can impart a "twist" into objects it illuminates, but the effect is typically very weak.  Chad at Uncertain Principles discusses an experiment that successfully measured this light-field torque... which was done in the 1930s!
  • What Is Beauty? Your Kids' Newest Art Critic.  Do animals have a sense for the artistic?  Jason at The Thoughtful Animal describes a study done to test whether pigeons can tell between good and bad art.
  • Why (and How) People of a Feather Flock Together.  We've all been stuck in crowds before, but science behind modeling such pedestrian traffic usually makes simplifying assumptions.  David at Mind Matters explains some new research that includes an important complicating factor: the tendency of people to travel in groups!

Check back next week for more "miscellaneous" selections!
