Did you know that recent model iPhone Pros have a LiDAR sensor? You can use it to measure distances, and scientists in Spain used it to recreate a digital version of a cave filled with ancient cave art. 🧪 #scicomm www.forbes.com/sites/evaams...

Mapping Cave Art With A Cellphone

Researchers in Spain used Apple iPhone’s built-in LiDAR sensor to create a 3D map of a cave with hundreds of prehistoric cave paintings.

We cover a lot of ground in this one: the ethics of publishing on Myanmar amber, article retraction, and whether Rob has any credibility. It's a good one. Give it a listen 👇

Because there's so much awful stuff to write about, I decided to write my latest column for @thenewworldmag.bsky.social about something interesting and removed from all that: the discovery of a blue pigment in a Neolithic artefact.
www.thenewworld.co.uk/philip-ball-...

How did cave artists get a brand new pigment?

The discovery of traces of a blue pigment on a stone shaped into a shallow dish at a Palaeolithic site in Germany is quite a find

Sudden urge to pitch an event called 'STOP BEING A FANNY ABOUT INSECTS' to a major festival. 'Jules Howard and special guest tell the audience to stop being fannies about wasps and flies and bloody well just replant their front driveway spaces to make a home for earwigs'. Too much? Yes. Yes it is.

#Paleoctober2025 day 7 paleoart sketch of the extinct conifer Sequoites.

#Paleoctober #Paleoart #Sequoites #Enantiornithes

The genus existed until the Miocene, but I chose the Late Cretaceous Sequoites dakotensis so I could include an enantiornithine bird. The juvenile avialan is begging for food from an unseen parent perched atop the conifer branch with a cone and speculative leaves below it. The scene is overcast with fine rain.

I haven't paid much attention to ferns in the past. Here's a green, graceful example common to the N. Hemisphere. Likes the damp, shady places that need some life.

feels like yet again time to mention that the *videogames* industry (that's a creative industry, which people do creative degrees in) brings in more than twice the amount to the British economy as the fishing and steel industries *combined*

Naomi Alderman @naomialderman.bsky.social · 13h

I cannot understand what these people think the purpose of human life is?

It is *not* "pursue joy, deal justly, love well, try to understand as much and see as much of this beautiful world and of the deepness, richness and variety of human culture and experience as you can before you die"?

Tim Worthington @outonbluesix.bsky.social · 13h

How is this repeatedly made into a policy issue - by *all* parties - when the blunt fact of the matter is that grown adults who are obliged to pay for their own education, and relentlessly pursued to repay their loans, should be able to study whatever the fuck they want.

Magnolias are much used as ornamental, flowering trees. I like the deciduous, yellow-flowered cultivars very much, even though their flowering period is brief. This is ‘Butterflies’, a cultivar of an interspecific cross. #Magnoliaceae #Botany 🌾🧪🌱
