Phylogenomics and genetic admixture of the invasive fireweed complex (Senecio inaequidens–Senecio madagascariensis) at a global scale - Biological Invasions
The southern African Senecio inaequidens–S. madagascariensis complex, (‘fireweed complex’), contains several species that have established as weeds outside of their native ranges. Senecio madagascarie...

We have expanded our target capture dataset of the Senecio inaequidens - S. madagascariensis complex to a global scale. More clarity on the areas of origin of invasive madagascariensis, but also raising new questions.

Trump is unpopular, but how do Democrats frame their arguments for a comeback?

I find this very frustrating. I would get it if this was some esoteric detail requiring deep expertise, but Ed Zitron merely had to summarise what was available about money in versus money out, and Altman himself admitted they lose money even on 200 a month subscriptions. This wasn't rocket surgery.
It’s so funny (and good!) seeing people come to conclusions I had in June 2024. I get why too, back then you were a lunatic if you did the maths on OpenAI and said it was negative 5 billion dollars! They would say you were mad…
This is the kind of stuff I USED to focus on before… all this shit.
A handy little update from Sasha on the rock and hard place AI and LLMs find themselves up against as the cost of improving accelerates while the number of people willing to pay flatlines-

Abuser's logic: look what you made me do now, you should have kept your mouth shut.
I’m going to repeat myself but: some who objected to these things did so precisely because they saw them as driving people to the Trumpian right, or as weakening defences against that outcome.
Years from now, it'll be difficult to explain the things people in media were wailing about before all this. Sophomores writing underconsidered op-eds about cultural appropriation. Protests against demagogues on campus. YA drama. "Mobs" on Twitter. These were the threats to free society.

This is so strange. The author thinks that it is normal and good behaviour for OpenAI to make available a plagarism bot and for himself to use the plagiarism bot for proposal writing, but that it is unexpected and terrible if clicking the don't store my data button leads to data being deleted.

I remember seeing The Matrix in cinema with a friend, and we were both laughing through most of it because we could just not take it seriously. The slow-mo trying so hard to be cool. The perpetuum mobile. People dying when you pull the metaverse plug, as if they had a soul that got disconnected.
For the kids of today, The Matrix is probably foundational to the point of being dusty. This is not a complaint -- The Matrix fuckin' BANGS -- just a reminder that time passes. It's not that kids today can't/won't see SF films before then, just that their eye on them will be very different.
Teaching a Science Fiction CW class today, and mentioned Kubrick's 2001 to illustrate a point. Out of 18, only 1 had seen it (and he wasn't super clear about it). To these—bright, creative, engaged!—20yos this was just some antique movie.

The equivalent in science is first having abstracts to summarise the content of research papers, journals then inventing 'highlights' to summarise them again, and now AI summarising them in a third and less reliable way. Has everybody gone insane?

Holy fuck I do not want an ai summary of my email thread at the top of the page by default. 1) I know how to read, and 2) I would rather spend my time READING THE ACTUAL FUCKING EMAIL

Interesting patterns here, but I see a few potential caveats. First, this all seems to be based on species numbers, not local biomass. Second, the cleaned dataset is 2815 taxa, a small fraction of angiosperm diversity, and IIUC, only fleshy-fruited taxa even when analysing flower colour?

Always find it fascinating how megafauna survived several cycles of warm ages and ice ages over two million years and then all rapidly went extinct everywhere from "rapid environmental change" when modern humans with stuff like spears or stone axes were around. That is such an enormous coincidence!
Woolly Rhino was not experiencing population decline prior to its rapid extinction ~14,000 years ago, based on DNA recovered from mummified wolf stomach in Siberian permafrost. Instead, extinction likely due to rapid environmental change.

Using an LLM for research is equivalent to using a hammer to exchange a light bulb.
It is a problem of our times, however, that research is now used to mean everything from a scientist running a double-blind experiment to somebody typing "invertmecin cure cancer?" into the Youtube search bar.

If we buy the theory that AI will keep improving, we also have to buy that a large part of the software that produces money today will be worth nothing. This is already happening for apps, and also for this community of "micro-saas" you mentioned. Why would I pay for something I can make for free.

The way modern authoritarian states work is not by canceling elections but by making it effectively impossible for the opposition to win. Cancellation isn't the risk; stuff like candidates being prosecuted or ICE harassing non-white voters at polling stations seems more plausible.
the question to ask about this is, okay, he wants to cancel the midterms. how does he get the VA state board of elections to cancel the midterms? how does he get the georgia board of elections to do it? how does he convince republican house members to quit their jobs and give up their paychecks?
Trump says a lot of deranged shit, but, per this Reuters article — and the threats of invoking the Insurrection Act in Minnesota this morning — he is very clearly exploring how to cancel the midterms.

I remain mystified why meeting software like Zoom doesn't automatically equalise the volume across different meeting participants. Maybe that is my ignorance as a non-programmer showing, but that seems both eminently doable and an obvious improvement to the user experience?
