In genetics:
'Trans-acting' = a gene exerts influence on another gene on a different chromosome.
'Expression' = when a gene produces an effect in the cell

They tagged two of the most common terms in genetic research for defunding because we put fascist tech-bros in charge of our science. ๐Ÿ˜

I have a billion dollar movie idea:

I just like the idea that way, way back, some early parrots just decided to go fast and kill things.

Yes, they are a basal branch of the parrot family. Murder Parrots!

These are the much younger Flinders Ranges examples - but that photo from Isua seems to show a much larger scale (but no scale marker!) The wiggly bedding with the pointyness is pretty diagnostic, but you also need the larger humpy shapes as well,

Not yet, as I was among a cohort laid off from my institution by neoliberal tories intent on cutting funds to science, so my journal access these days is patchy!

Where's the Shovelware? Why AI Coding Claims Don't Add Up 78% of developers claim AI makes them more productive. 14% say it's a 10x improvement. So where's the flood of new software? Turns out those productivity claims are bullshit.

I'm not even sure that tons of software is being produced. It certainly wasn't the case when this was written in September 25 mikelovesrobots.substack.com/p/wheres-the...

I can't currently access the paper, but the images of the Isua structures do seem to look like stromatalites I've seen in the Brachina Gorge in South Australia, with a similar cross sectional structure.

Maximum wave height plot for 16/2/2026 at the mouth of Wellington Harbour NZ, showing wave heights climbing from 1, to 2, then a step up to sustained heights between 5 and 10 metres over the 15th, to a peak of 13 metres early on the 16th of February.

So the wave buoy at the entrance to the harbour recorded a 13 meter wave this morning:

Don't think too hard about all the grogans surfing in on that from the failed privately owned sewage centre that had to shift to the short outfall pipe again in the storm last night.

Even if they do leave the building, they take time to save their work, finish that email, pack their bag, etc. Thus ensuring in an actual event, they're one of the casualties.

Sighs in Health and Safety rep who's experienced most types of accidents firsthand as a participant or bystander. On sites where there are regular tests of the fire alarm, there are people who will ascertain if it's a test, and then either take their time to evacuate, or will just keep working.

I suppose what I left off this would be the incipient/buried rangefront faulting under the Canterbury Plains that introduced itself with the Darfield 'quake in September 2010.

Screenshot describing an incident where a fire alarm went off, and someone in the office checked with the work slack channel to see if it was a real alarm, and the AI assistant assured them that it was a scheduled test and not to leave the workplace.  It was a real fire alarm...

So, it's ok if we use these chatbots to run safety critical messaging systems and stuff in our internal systems, right?

Current working idea is that the historical injury photos of my right retina either pinged an automated 'Gore' image moderation function, or, given the round shape with veins, maybe a 'Boob' automated moderation function.

Most of the generic plate boundary/subduction zone/continental breakup ones were done so that they could be strung together as A1 printouts and then coloured and annotated for school students. We also used a set for the rock display at my childhood schoolhouse, which became a museum at Staveley.

A more NZ specific one - what was going on in the Canterbury region ~95-100 million years ago as Zealandia, now welded to the paleopacific after the collision with the Hikurangi plateau (and possibly a spreading ridge on the Phoenix plate) jammed the old gondwana margin, we rifted, and drifted north
