Any day with a #zircon in your feed is a good one - even one like this that clearly has some stories to tell... ⚒️🧪

Really interesting fracture morphology to this zircon (from an Archean shear zone in s. Ontario's Superior Craton). It looks positively dilated in the brittle realm: onion skin style sheeting along growth bands and then further blown apart along those new intracrystal mechanical discontinuities. ⚒️

Photomicrograph of a black and white crystal with numerous internal concentric layers of white and gray. Radial fractures cut across numerous layers but truncate at the top and bottom of those layers, implying the layer boundaries themselves are mechanical discontinuities. Scale bar 100 μm

This is amber. It looks like a rock, but does not count as one. If you would like to learn more about rocks and minerals: in four weeks, it's time again for this year's #Mineral Cup, where we search the mineral of the year 2026. Find out more: www.mineralcup.org #MinCup #MinCup26 #Minerals ⚒️

Amber necklaces, two large and several small pieces of amber.

A tōtara in the great forest of Tāne has fallen... Sam Neill's portrayal of Dr Alan Grant in the Jurassic Park films is what many people now think of as a ⚒️🧪 paleontologist (or perhaps even a 'scientist'). His portrayal as an unlikely action hero with humanity and brains serves us all well.

Sam Neill, Jurassic Park actor, dies aged 78

The New Zealand actor, who was born in Northern Ireland, died in Sydney. "The loss was sudden and unexpected," his family says.

10 June marked 140 years since the volcanic ⚒️🧪 eruption of Mt Tarawera near Rotorua 🇳🇿. My main memory of this famous image is as a slide in 1st year geology course where the lecturer pointed out the figures in the middle: 'Look how excited they are! They must be volcanologists!'

A vivid 19th‑century illustration of Mount Tarawera erupting at night, with bright red and orange lava and ash shooting into a dark sky. The fiery glow reflects across a calm lake in the foreground. Small huts and figures from the village of Wairoa stand near the water’s edge, dwarfed by the dramatic volcanic explosion. Chromolithograph based on a painting by Charles Blomfield, depicting the volcanic eruption of Mount Tarawera on June 10, 1886, seen from the village of Waitangi, Lake Tarawera. The chromolithograph was made by William Potts, and was published in E. Wakefield’s publication 'New Zealand Illustrated', published by A.D. Willis Ltd in 1889. https://natlib.govt.nz/records/22750114

Sounds intriguing, there is more detail here: spaceweekly.com?p=801385. Although the concept does raise images of large horseshoe magnets and misguided coyotes. Better check that this isn't being sponsored by Acme Corporation...

A new spacecraft concept called NOVA could keep asteroids from hitting our planet by using a huge magnet to gradually pull them apart while shifting their trajectories

The meaning of precision in geographical degrees. ±100°: You don't know where it is. ±10°: You know it's on a specific continent. ±1°: You know it's within about an hour's drive. ±0.1°: You could bike to it. ±0.01°: You could walk to it. ±0.001°: You could probably see it.

Scientists: for a new story, I have one big question—> What is a “good day” in the lab? I’m looking for epic examples of the best day ever to general criteria for what constitutes a “good day” compared to a nothing-burger day. Ping me if you have examples to share! Re-posts appreciated!
