As notícia hoje em dia tão tipo "China desenvolve a bateria que não acaba o panetone que não engorda e a cura pro bico de papagaio" "Estados unidos: a ultima moda é cagar na calça para diminuir custos. É o pants cagation"

In case you're counting, the planet is now on day 6 reaching a global surface temperature above 17.0°C. The only other years reaching 17.0°C since records began in 1940, and likely in the last 120,000 years, were 2023 and 2024. Next year will be much hotter.

I can't speak to the traditional beliefs about it, but I can say that it's a neat reminder of how our brains use context cues like shadows to ground objects in reality. When we experience a moment that doesn't fit our mental model, we 'glitch out' & well... "the sun rests on the brains" FITS.

A yellow construction level has been placed on a sidewalk vertically so that it casts no shadow at Lahaina Noon in Hawaii. From a physic forum.

The "zero shadow" phenomenon is only true for perfectly vertical straight-sided objects, but it's trippy to look at. The State Museum of Natural and Cultural History of Hawai'i ran a contest to come up with a name & landed on 'Lāhainā' which means "cruel sun" in Hawai'ian.

From a physic forum, some hi-vis yellow pedestrian bollards in a parking lot cast no shadow. on the yellow hi-vis non-skid strip outside a grocery store. In the background is a hauler truck and an SUV.

Twice a year, Hawai'i experiences a strange moment where the sun appears to be exactly overhead & anything that is completely vertical casts no shadow. Let's learn about Lāhainā Noon, subsolar points & 'Kau ka lā i ka lolo', meaning "the sun rests on the brains."

From a Reddit forum, a photo of a can of coconut milk with a blue label, papyrus text and a flip-top, on a sidewalk. It seems to hover because there's no visible shadow. The pavement is sort of unevenly colored, with bright spots, and the grass along it is green and lush.

I think this doesn't get said enough; transportation advocates *know* more than most people that living without a car is nearly impossible in most places and it is BY DESIGN. They (we) advocate for changes to that design to make alternatives possible. The goal is for people to need cars less.

The War on Cars@thewaroncars.bsky.social · 3w ago

Nobody disputes that having access to a car in a car-dominated society is good. It gives one access to jobs, healthcare, food, education, social opportunities and more. All we're asking is for people to go one step deeper and ask why access to such basic rights requires buying and operating a car.

Todos os partidos devem ter meios de fazer sua campanha, mas o acesso deve ser proporcional à sua representatividade social e política. O problema do sistema atual é que se assume que a representatividade já é dada pelo resultado da urna da eleição anterior Esse pressuposto é falso

Chord diagrams in R with ggchord2 – Nicola Rennie

Chord diagrams can be used to show relationships or flows between and within categories. This blog post introduces ggchord2, a new package that makes it possible to create them using ggplto2 in R.

How far do intergenomic compatibility shape ageing trajectories? 🦠🧬🪰 Our latest study in PNAS @pnas.org, explores this. Check it out! doi.org/10.1073/pnas... Thanks to an amazing team: @fcamus.bsky.social, @dk-dowling.bsky.social, Avi & Finley. #mitochondria #mitonuclear #ageing #diet #hormesis

Mitochondrial decline is a hallmark of ageing, yet the role of intergenomic compatibility in shaping ageing trajectories remains poorly understood,...
