As the athletes take centre stage at the Vancouver 2010 Winter Olympics and Paralympic Winter Games this month, chemists will be hard at work behind the scenes to catch athletes looking to win by taking drugs or blood products to artificially boost their performance during the competition.

Nine years ago, Chris Hunter's group at theUniversity ofSheffield in theUK reported that they could use a zinc ion to tie an open knot in a linear oligomer.1 But ask a mathematician, and a knot isn't a knot unless it can't come untied - no loose ends allowed. ...

As every schoolchild knows, water freezes at 0oC. Or perhaps not. It has been known for centuries that pure water, in the absence of any nucleating surface, can remain in a supercooled liquid state down to temperatures as low as -40oC. ...

US researchers have found a way to scale up DNA origami into larger structures by using 'tiles' instead of 'staples' to pin them in place. Scaling up is crucial for the further development of DNA origami, which has great potential in providing cheap access to complicated nanostructures.
