How much of someone else's pee could you be swallowing while taking a swim? And is it dangerous?
Risk Bites takes on the terribly important topic of peeing in swimming pools. Surprisingly, beyond the yuck factor of drinking someone else's urine, there is a more serious hazard - production of cyanogen chloride from the reaction between uric acid and chlorine. To find out whether you should be worried about this -- watch the video!
Should you be worried about being exposed to bisphenol A (BPA)?
The European Food and Safety Agency (EFSA) recently released its latest (draft) scientific opinion on the risks to public health related to the presence of BPA in foodstuffs. As it's over 500 pages long, we thought we'd summarize the highlights in a rather shorter Risk Bites video!
Could alien blood be toxic?
Of course, the chances that exo-toxicology becomes a critical issue in our lifetimes is small. But with rapid developments in fields like synthetic biology, it may not be long before we have to ask serious questions about the risks associated with home grown "alien" life forms.
Are electronic cigarettes bad for you? Risk Bites takes a look at the pros and cons of e-cigarettes, including research that suggests the materials e-cigs are made of may cause problems if not regulated well.
And we end with a bit of a twist as other ways these vaping tubes could (and are being) used.

To make things a little easier, "micromorts" and "microlives" can help make sense of the risks and benefits of what you do -- and what you don't do.
