This week saw the news that the International Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP) have decided that two new elements can be added to the periodic table. This follows a three year review of the elements to ensure that they fulfil the official criteria which has seen three other potential new elements fall by the wayside. The new elements sit at atomic number 114 and 116 on the period table, and are as yet not officially named, but are going by the snazzy unofficial names of ununquadium and ununhexium. However, don’t expect to see these new elements sitting on the shelf of your chemical store any time soon, not only are they highly radioactive, but they only exist for under a second before decaying.Discuss

When chemicals spill out into the world around us, we need to know what consequences they will have. In general, an opinion of “what doesn’t harm is fine” holds – both for ecotoxicological tests, used to determine the adverse effects of contaminants, and in the community overall. Indeed, it is quite intuitive. But what if … More

The birds, part of the crow family, are often celebrated for their intelligence. Magpies are capable of storing food over winter and remembering its location, even remembering which other … More
Here’s a simple idea: You have three pigeons and only two pigeonholes. If you put the pigeons in the pigeonholes you’ll end up with at least one hole that contains two pigeons. Right? Now let’s consider quantum particles. What if you have three quantum particles and two boxes and you try the same thing? Well, … More
