How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
Large stars die, and then explode into massive supernovae. This scatters all the elements of the periodic table throughout the Universe, which results in the third threshold of complexity -- the creation of chemical elements. Website: https://www.bighistoryproject.com/portal Facebook: https://www.f
Pluto may be a former planet, but it's also a novel way to think about risk! On July 14th 2015, a small spacecraft will buzz a former planet in the less fashionable outskirts of our solar system. A lot of people will get excited by this, apparently thinking that the first close-up view of a lump o

A tongue in cheek look at the potential dangers associated with water - that at the same time sets the scene for some rather intriguing future videos on risk and safety. For more information see http://riskbites.org/2012/08/16/ten-ways-water-can-kill/ Water, ice, steam, risk, health, science, safe
How do you go about avoiding becoming infected by a harmful airborne virus like COVID-19 -- especially if you're a student heading back to campus? There are, of course, a number of blindingly obvious ways to do this. However, because so many people seem to have forgotten them, I thought it worth p
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms. Chemical reactions can
