Extinctions serve as important warning signs that something is very wrong in the environment. Will we finally heed these warnings? Our mental wellbeing and over half our economy depends on it. theconversation.com/and-then-the...
And then there were none: Australia’s only shrew declared extinct
Australia’s only known shrew has been declared extinct. Its loss emphasises the need for national protection of Australia’s rare and unique wildlife.

And it’s a hit! My #SnakeWheelOfFortune poster game has been played by dozens (possibly 100s) of kids & adults across Qld for #NationalScienceWeek & beyond, & they’ve all left with a far greater appreciation & respect for snakes. Education shapes perceptions, & perceptions shape behaviour 🤓🐍💚!

Introducing the #SnakeWheelOfFortune poster! In working w/ dozens of snake educators from over 23 countries, I saw a major gap in our education re snakes. We all needed a simple, powerful visual to explain the many benefits of snakes to people. After 1yr of design & peer-review, it is now published!

#NationalScienceWeek was a super success! Such a privilege to be able to engage w/ communities in rural/remote/regional Queensland as Inspiring Australia’s ambassador this year. These folks often miss out on #STEMed, but not this year! Thanks to Dr. Anita Milroy for her connections and vision.

New paper! We studied venom coagulation of 🐍 from the understudied pit viper genus Bothrocophias. This genus of pit-vipers, sister genus to the more well-known Bothrops, has 9 recognised species, & are relatively restricted in range, occupying Andean South America & equatorial Brazil…(1/4 posts 👇)

A new sustainability standard has been set for conference lanyards! This #ICCB2025 one is compostable & plantable! Native seeds r embedded into the name tag so local delegates encouraged to plant it for habitat. How good?! As paying delegates, we can and should ask for sustainability like this 😎💃
