Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor ...

For low-cost DNA nanostructures, recycle sticky ends
Scientists from Duke University have recently demonstrated a new method for assembling large, low-cost DNA nanostructures, in part by reusing the “sticky-ends,” the broken DNA strands used to connect the nanostructures. ...

'Finger rafting:' Ice sheets that mesh when they meet
A study reported in Physical Review Letters demonstrates how ice sheets sometimes interlace when they meet, rather than riding over or under each other, and discusses the implications for other phenomena from p ...
