Allan Blackman tells us the history behind the Periodic Table to celebrate the International Year of the Periodic Table 2019, we hear about the problem with the process of desalination, and a handy way of remembering things.
On Dear Science today we hear about a new, quick, way of testing for cancer, the Voyager 2's 41 year long journey into interstellar, and dangerous soya sauce "cleanses".
Lots of grim things today on Dear Science - we talk about one of the deadliest scientist, and why you really did not want to be alive in year 536, because it really, really sucked. But we finish on a cute note with some very much needed explanation about wombats’ square poop(s?).
For Dear Science we talk about alkaline water, age ratings in films being determined by chemistry in the air, and wrongful criminal drug conviction cases due to misconduct in the lab.
