Two redwood sampling pictures from the archives. This tree cross-dated really well from 1996 to 450 CE.

It fell in a storm during the winter of 96/97 in the Rockefeller Forest area of Humboldt Redwoods State Park.

It was tricky to cut because it was partially buried in the soil from when it fell.
A man standing on top of the lower section of a large coast redwood tree that is egg-shaped in cross-section. He is holding up a very large chainsaw to try and line up his cut. The cross-section is buried up to 18 inches deep in organic soil from when it fell during a storm. Same as previous image but now the man is bent over actively cutting a cross section with chips flying straight up in the air.

We're all set up and ready to go for the arboretum open days THIS WEEKEND! Come and see the world's most diverse collection of eucalypts, with over 800 species growing on the one site.

About an hour's drive south of Adelaide in SA. Open day details here: www.dn.com.au/Currency_Cre...

with the official IUCN listing for the slender-billed curlew now being Extinct here is the rather sad piece I wrote about what went into this decision

I tried to include everything we know about their behaviour and biology, which is tragically little 🪶🧪

Fire management in the red tingle forest of southwest Australia has been a hot topic for a few years now. New research from @natesanderson.bsky.social suggests that the red tingle forest should be managed differently than the nearby Karri forest, to reduce tree mortality.

Fig. 2.Plant proteases involved in various stages of plant life cycle, organelle import, and responses to abiotic or biotic stress. Important processes and pathways regulated by proteases mentioned in the text are indicated, and proteases investigated by N-terminome approaches are named. Green cells represent healthy cells, while (dark) brown cells represent dying/dead cells. The apoplast is displayed in grey color. Nitrogen-fixing bacteria are schematically depicted in red colour, the cyanobacterium Synechocystis is indicated in the puddle next to the plant, and the green alga C. reinhardtii in the soil. Blue and violet ‘Pac-Mans’ depict plant and pathogen proteases, respectively. Created in BioRender. Huesgen Lab (2025) https://BioRender.com/6aue2gv.

The Aust Parliament Sports Club (the one that ditched David Pocock) is now formally registered as a lobby group👇🏽

Anthony Albanese is the President of the Aust Parliament Sports Club.

That means the Prime Minister of Australia is currently the president of a lobby group.

Just utterly unbelievable.

No surprise that despite majority community support we still don’t have a ban on gambling advertising when the Albanese government accepts money from companies like Sportsbet for their fundraising.

When will they put Australians ahead of gambling companies?

Even after being found guilty of 'officer misconduct' for mishandling the Robodebt referral, Commissioner of the NACC continues consultancy role despite concerns of perceived conflicts of interest.

At $820k/year surely he can focus on doing one job well?
