Dogs tilt their heads

Tuesday 28th June 11:30 am

Dogs tend to hang around humans but do they really love us—and what’s with the head tilt? Their affability might be due to two genes known to influence sociability in mammals. Gradually genetics turned dogs and humans into best friends.

Measles erases immune system memory

Tuesday 21st June 11:30 am

Measles is a nasty infection that you don't want to get. It can cause death and, what's more, it can also erase your immune system's memory. Only relatively recently scientists have measured this directly - by concentrating on antibodies – which can be generated by natural infection, and by vaccines.

My favourite children’s book growing up was ‘Thunderbolt of the Spaceways’. ABC Perth are asking for donations of new children’s and young adult’s books for their Brekky Book Bank. The books will be given to disadvantaged children across WA. Children’s books can bring back so many happy memories and if you’d like to share that magic with children, donate your books to the appeal.

It's #GeekPrideDay! 🎉One of my favourite pieces

It's #GeekPrideDay! 🎉One of my favourite pieces of Science Kit is the Galileo Thermometer (not actually invented by Galileo). It's a lovely combination of Function and Form (+art that is useful, like a tea towel).
Water will change its density a little bit with temperature, but ethanol does it 3.7 times better – and the modern liquids in a Galileo Thermometer are better again. This liquid is inside a sealed container – to avoid the effects of the changing air pressure.
Inside the container are a bunch of hollow, weighted glass balls – each carefully calibrated to have a different density, and each with a brass tag indicating the temperature. The single ball that is floating freely indicates the temperature of the liquid.
So what is your favourite super-geek item/collection, and why? And is it useful or beautiful, or both, like the Galileo Thermometer?
