A rendering of the new spray bottle

The average household contains at least a few spray bottles filled with liquids that ... well, that children shouldn’t be playing with. While most bottles now incorporate nozzles that can be “turned off,” many people don’t bother doing so, plus kids can just turn those nozzles back on themselves. The situation has led to the design of a new type of child-resistant spray bottle, that has two triggers.  Read More

The Dip Chip biosensor, with a key for scale

Once upon a time, tasters were employed by the well-to-do, in order to check that their food or drink wasn't poisonous. Today, there are electronic biosensors that can do more or less the same thing. Unfortunately, as was no doubt sometimes the case with the tasters, the biosensors can’t always give us immediate results. Additionally, they’re usually only able to test for specific substances, and not simply for “anything that’s toxic.” An experimental new device known as the Dip Chip, however, is said to address both of those problems.  Read More

The toxin is produced by the Clostridium Botulinum bacteria - and scientists at the UK's Wellcome Trust Sanger Institute have just completed some fascinating genome research on the development of this incredibly effective killer and its survival mechanisms. Where some bacteria use complex and even elegant methods to dance around our immune systems, C. Botulinum goes for the direct hit with a "microbial sledgehammer." More please, just around the jawline.  Read More
