We all know the Periodic Table of Elements — it's that thing with the pretty colors that hung on your chemistry class wall. While we may all recognize the venerable chart, we may not really know it (unless it's done up as a Star Wars version). Now, students and science buffs can actually interact with it thanks to QR codes for each element.
 
Bacteria are a nasty bunch, creating infections from the common to the horrific. Not only that, but they lurk pretty much everywhere. Now they may have met their match in a film created by Harvard scientists that is so slippery, it fools bacteria into thinking they can't attach there and grow. Major score for science!
 
In the future, police may analyze highly detailed, glowing fingerprints instead of dusting a crime scene. A research team in China has developed a process by which fingerprints both old and new are not only more detailed, but could allow authorities to pick up extra evidence, such as drug use.
 
As a kid, I'd sit watching Star Trek and it would blow my tiny mind. From the phasers to the universal language translator I was fascinated by this imaginary future, not realizing I'd be living in a time when many of the things envisioned by Gene Roddenberry are close to coming true.
 
Single-celled creatures on the lam, beware! Scientists have devised a method utilizing ultrasounds to hold small bits of matter (including living cells) by seemingly invisible means. The technique, called "acoustic tweezers," appears in the current issue of the Proceedings of the National Academy of Sciences.
