Happy Thought for 21 October 2022

Have a Happy Thought:

Creatures on this planet are far weirder than anything sci-fi writers and CGI artists can dream up. Here’s a few examples (that will, no doubt, inspire both writers and artists):


A peppermint stick insect (Megacrania batesii). As a defense mechanism, it shoots a spray that, to humans, smells like peppermint.

 Southern Pink Underwing Moth (Phyllodes imperialis smithersi). The caterpillars develop “eye spots” and “teeth” that they can show off when alarmed.


 

Venus Flytrap (Dionaea muscipula)

 Crinoids (class: Crinoidea). I mean, once you go into the ocean, we know things are going to be weird, but seriously!

In fact, Crinoids are so weird they need an explainer…


 

 

An unrelated, but important bonus topic: Bird of the Year 2022 has begun. Voting is open until 5pm on Sunday 30 October (New Zealand time).

The best part about this is the social media frenzy that erupts. From city governments to the Prime Minister to overseas diplomatic posts, everyone picks a contestant to back.

Happy Thought for 30 June 2023

Have a Happy Thought:     At the end of this week, possibly as you are reading this email, you get to have some separation between work colleagues and home life. (If you’re retired… well, I’m already jealous, so don’t @ me with a “ what is a week-end ” sort of quote).   But four very lucky people (yes, I’m somehow jealous of them as well), this week began a 378-day “week”, being shut in with their colleagues.   June 25 2023 was the start of the CHAPEA Mission 1 - a simulated Mars habitat at NASA's Johnson Space Centre. For just over one year, these four people will live as if they were on Mars, giving us valuable insights into logistics and human psychology. You can watch the emotional press-conference / shutting-the-door-behind-them , it’s actually very cute!

Have a Happy Thought:     The new James Webb Space Telescope (JWST) is opening up the origins of the universe and very distant galaxies, stars and exoplanets to our understanding.   You’d think we’re only looking that far because we’ve figured out how everything works closer to us, right?   Wrong! Science is great because there’s always something new to explore and figure out. Here are just a few of the mysteries that remain for us to solve, or maybe just a few things you didn’t know, right here in our own solar system:   Q: What is our sun’s surface actually made of? A: We’re… not 100% sure, actually! We know mostly, by analysing the light that comes from the sun. You see, every time light passes through an object, including a bunch of gas, it changes the spectrum that we see – that object, or gas, absorbs some of the energy of light at specific wavelengths (or sometimes absorbs-and-re-emits-at-slightly-different-wavelengths). So astronomers can tell what gasses a sta

Happy Thought for 26 January 2024

Have a Happy Thought: While some of our holiday breaks may be fresh in mind, others may be distant memories. Either way, I hope you’re entering 2024 with at least some positive energy. One way to hold on to that (or maybe create it if that’s what you need) may be to introduce frequent, but short, breaks into your day, ideally getting out into some blue- or green-space.   Image: A stump next to a tree-shaded pathway has had googly-eyes drawn onto it so it looks like a startled face. Picture by author. In fact, taking mini-breaks might benefit your physical health as much as your mental health! A recent study out of Columbia University in the US has found that taking frequent-but-short breaks, 5 minutes out of every 30, can have really impressive impacts on physical and mental health like: Blood sugar Insulin Blood pressure Mood Fatigue Cognitive ability  (apparently, I need this a bit, it took me three tries and spell-checker to spell cogni
