- NewsA new humanmade version of an insect's compound eye could perform like the real thing.
- NewsAn atomic-force microscope tip has been transformed into a microinstrument for sorting DNA and depositing nanostructures by means of cleverly applied voltages that propel molecules along the tip's surface.
- NewsPairs of tiny gas clouds of unequal energies mixing inside narrow tubes retain their original energy differences.
- NewsResearchers have found signs that one of the constants of nature has undergone a subtle shift since the universe's infancy.

- NewsA new type of eyeglasses that change their focus in response to electric signals may one day replace bifocals and other types of reading glasses.
- FeatureThe recent merger of high-speed video technology and centuries-old techniques for seeing ordinarily invisible fluctuations of the air is enabling engineers to visualize and study the previously unseen, large-scale behavior of shock waves in explosions and aerodynamics research.
- NewsThe extraordinary performance of a prototype superconductive wire is encouraging superconductivity specialists, even though the prototype is unlikely to be mass-produced.
- NewsA new microscope system uses electrically controlled fluid motions to counteract Brownian motion, preventing those random jitters from driving proteins, viruses, and other tiny objects out of the field of view.
