A mixed bag for this week’s Sunday science, with dinosaurs, microbes, toilets and, er, voters (today’s challenge: put those four things in a sentence that makes sense!).

The featured image is an artist’s impression* of three dinosaurs in a new fossil that were found huddled together, possibly for warmth. They may have engaged in “communal roosting” like some bird species.

Hotter weather is known to increase incidents of violence. Now it seems it can influence voter behaviour (link to original research article). I find it somewhat ironic that Al Gore, famous for his work warning on climate change, might have won the 2000 presidential election if it had been just 1C hotter in Florida that day.

A technical one for the microbiologists. Sequencing of microbe DNA fragments in human blood has revealed that hundreds of unidentified species that live on or in us.

Finally, a weird one from Science Daily in July: mixed sex toilets reduce queuing time. I’m fascinated by this primarily because there are people in existence who are “queueing theorists.” Can you imagine the “So what do you do for a living conversation?”
