How processed food companies muffle those who author studies that put them to shame:

"One large food company, for example, asked if he would be interested in giving a half-hour talk to its senior team, for a fee of £20,000. He said he would, but he’d pay his own expenses and give the money to a food charity.
When the contract came through, he changed his mind. Within it was a clause binding him not to disparage the firm in public statements, “throughout the universe and in perpetuity”."

On pizza, I entirely second Chris van Tulleken's statement: “Pizza has become emblematic of junk food ... but proper homemade pizza is very healthy.” The hilarious bit is that making pizza at home is easy peasy: just make baguette dough (takes you 5 minutes to mix, a couple hours to raise https://albert.rierol.net/recipes.html#Fast%20baguettes%20for%20everyday%20bread ), then roll flat and top with whatever you like or happen to have at home.

A set of last-year undergraduate students could figure out how to muffle the sound of a leafblower, but the billion-dollar companies that manufacture them could not be bothered for decades.

Another unusual insect: Tenthredo baetica (ssp. dominiquei), with only 118 observations world wide, of which 29 for this particular subspecies. It's a wasp – sort of: a sawfly.

The rear limbs are rather large, and I wonder why. For carrying prey?

https://www.inaturalist.org/observations/216752296

Wikipedia points out an interesting reversal: in the Tenthredo genus, the larvae eat plants while the adults prey on other insects. Whereas many typical wasps do the opposite: the adults sip nectar but hunt insects to feed their young. https://en.wikipedia.org/wiki/Tenthredo One wonders then what is this adult doing on a flower, engaging in motion patterns characteristic of foraging on nectar and pollen.

Another attempt to mobilise you for !
This is a bread I bake from time to time, the recipe is quite simple but it takes time because it's a cold fermentation, which means the dough needs to be left in the fridge for at least 12 hours.

I know Tomas @tf is baking ... anyone else?

albertcardona,

@TomaszSusul @tf

Lots of us bake. For me, it’s a daily ritual: arrive home from the afternoon schoolrun, mix flour, yeast, water, salt and olive oil swiftly, let it sit warm for 2 or 3 hours, roll the baguettes and bake them for breakfast the next day. Costs me less time than getting to the bakery and back, and I always get the bread I want, varied in its flours, texture and taste. All it takes is planning and patience.

There’s also the tag – imported from other corners of the internet.

"What do you mean by progress when you talk about AI?" and progress for whom?

I asked the techno-optimist guy at an AI Hype Manel!

  • Does progress mean getting bigger or better models?

  • What about the impact on environment, water resources, destruction of communities, mining raw materials in Africa?

He first didn't get my Q. Then he said he believed in the "utilitarian view" & developing intelligence is very important.

Just parroting the AI hype people!

@OmaymaS

An AI hype guy was telling me today how AI replaces thousands of apps. I asked him (it's always a he) how many applications did he use in his laptop: 6. Seem unfazed. I asked then what applications he found useful, and after some discussion, it came down to drawing up posters, websites, and the like, for advertising, overcoming his lack of skills in the art department. I.e., spam, without an expectation of engaging with the recipients. Broadcasting. Indeed chat bots and generative AI are a boon to the spam industry.

It's hard to speak to the convinced. Guess when ChatGPT starts charging lots per subscription they'll rethink their starry-eyed stance.

@OmaymaS

Indeed. And on that, any gains in efficiency of ANNs implementation or GPU tech are squandered by ever growing neural networks. The scale currently is horrendous; the electricity and water usage is outlandish. One wonders, was the choice of clean water or "AI", what would the fanboys choose then. At the moment they choose "AI" for themselves and water shortages for others.

There are two paths to success in modern academic science.

  1. Be the gatekeeper for access to funds/resources and dictate conditions favorable to your public image.

  2. Do good science with as few resources as possible and get lucky.

Can you guess which is more common?

albertcardona,
@albertcardona@mathstodon.xyz avatar

@tdverstynen

I guess we could discuss what "success" means, and what "get lucky" means.

The first choice reads horrible, as in, as formulated, only an individual not actually interested in science but on the accolades would do that.

The second choice is, to me, academic research as usual. It's amazing how much a laptop, experience, ingenuity, and a network of friends and collaborators can accomplish, even without a budget. And the journey and the nurturing personal relationships are the reward; the end goal is always yet another metaphorical lush valley, jungle, or sea floor to explore.

Not a mosquito but a Cecidomyiinae, likely of the genus Lasioptera sp: a kind of gall midget or gall gnat.

https://www.inaturalist.org/observations/81412856

From a lucky shot in focus back in 2021. Thanks to the community for the ID. With Cecidomyiidae being a family likely more speciose than even beetles [1], the chances of identifying this animal are slim.

Disquieting #OpenScience thought:

@aeryn_thrace

Can only be seen as specious if someone authors more papers than is humanely possible to read and write in a year.

An average of 3 papers as senior author per year is already a lot of work.

This is par for the course in what I call the Exploiter Economy:

Addiction-optimized platforms that strip away our free time and bombard us with ads. Products designed to extract maximum value from users while returning the bare minimum. And always, the creators get the short end of the stick while Big Tech laughs all the way to the bank.

Dr. Núria Cortadellas and her colleague Almudena Fernández taught me electron microscopy – so grateful for all the time they shared with me and the opportunities granted.
