(Phys.org) —Is it possible that a moving object could have zero energy? The common sense answer is no, since motion itself is kinetic energy, but this answer has been challenged recently by the concept of quantum time crystals. ...
A new pitfall trap designed to capture bed bugs is more effective than those currently on the market, according to the authors of an article appearing in the next issue of the Journal of Economic Entomology. The authors also ...
