The biggest stories in science 2017
As we head into 2018, it’s time to take a look back at some of the biggest science news stories over the past year. This year’s science news featured poisonous frogs, battery fires, element creation, and more!
The Chemistry of Poisons
White Arsenic
This graphic is the first in a planned series looking at the effects and chemistry of a range of different poisons. As such, it seemed appropriate to start with one of the most well known poisons: arsenic. Arsenic has been used by poisoners for centuries, primarily in the form of white arsenic, ...
The Chemistry of Poisons
Cyanide
The second in the series onpoisons looks at cyanide, another notorious agent of murder.It’s played a role in genocide,in suicide pills, and is also found in small amounts in the seeds of numerous fruits. So, why is cyanide so poisonous, and why are deaths from cyanide poisoning less of a ...
The Chemistry of Poisons
Thallium, ‘The Poisoner’s Poison’

The Chemical Compositions of Insect Venoms
Insect venoms are complicated.Really complicated. You could be forgiven for thinking that it must be a relatively simple company of chemicals that makes up the painful sensation of a bee or wasp sting, but in fact a hugely complex mixture of all sorts of compounds – proteins, peptides, enzymes, ...
