Chemistry World April 27, 2006	Arrays Learn to Multitask Researchers have increased the information density of microarrays without further shrinking the dimensions of the spots. Instead, they used a combinatorial approach that involves multiple usage of each spot, known as multiplexing.
Chemistry World April 25, 2006 Jon Evans	DNA Sequencing Reaches the Space Age The smallest ever DNA sequencer, only 10cm in diameter, comprises a complex network of microscopic pumps, valves, heaters and electrophoresis channels, many of which were initially developed for use in a device to detect life on Mars.
Chemistry World April 24, 2006 Jon Evans	Putting Some Backbone Into Bacterial Killers Chemists developed a novel folded oligomer (foldamer) that is highly effective at puncturing bacteria and could form the basis for a novel class of antibiotics.
Chemistry World April 21, 2006 Philip Ball	In the Blink of an Eye Researchers have found that there's much more to tears than salty water. The liquid film that moistens the eyes has a coating similar to a cell membrane, which keeps debris and bugs out while holding water in, and is structured so that it doesn't get broken up each time we blink.
Chemistry World April 18, 2006 Jon Evans	Viruses Display Liquid Crystal Control Researchers have discovered that viruses can control the orientation of liquid crystals. Harnessing this ability could aid the development of nanomaterials and biosensors, they claim.
Chemistry World April 14, 2006 Simon Hadlington	Deciphering Hydrogen Tunnelling in Enzymes Researchers have thrown important new light on the phenomenon of hydrogen tunnelling in biological catalysts. The finding is likely to spark a debate among biochemists about the fundamental nature of enzymes.
Chemistry World April 11, 2006 Jon Evans	Nanotechnology Tackles Chemotherapy Chemists and medical researchers have developed nanoparticles that target chemotherapy drugs directly at tumours. The researchers claim that the same technique could be used to develop nanoparticle-based treatments for a wide range of other diseases.
Scientific American May 2006	Don't Rob the Cradle In his 2006 budget, President Bush slashed funding for the National Children's Study, designed to ferret out the causes of a multitude of today's most dire and growing health risks, and in his proposed 2007 budget, he eliminated its funding entirely and directed that the study be shut down.
Science News April 22, 2006 Janet Raloff	Do People Know When They're Overweight? A new study finds that most people can estimate their height-weight combinations fairly accurately. However, overweight and obese people miss the mark when they're asked to characterize the healthiness of their weight-to-height status.
Reactive Reports Issue 54 David Bradley	Hula-Hoop DNA Amplification Periodic nanostructures made of gold nanoparticles and long DNA strands with repeated sequences have been prepared by using a technique known as "rolling circle amplification" or the "hula-hoop" technique.
