🛫 Research flights in the Arctic
As part of the international COMPEX research campaign, scientists from #UniCologne, #UniLeipzig, and @awi.de are investigating how clouds and sea ice interact—and what role these interactions play in the rapid warming of the Arctic.

astronomy is so funny because it's this fairly niche interest for a small community of nerds and also it's 99.9999% of everything that exists

Map showing surface weather station observations on 9th Mar 2026

Certainly not the most important issue with the current situation in the Middle East, but there is a new Iran shaped hole in our surface weather observation network.

In this example, measurements of surface pressure fed into operational weather forecasts: 9th Feb (left) and 9th Mar (right)

Cropped screenshot of the Cigar Galaxy, M82.

Stacked and Stars Removed (except for the ones closest to M82 because StarX kept removing the starburst regions). Otherwise unprocessed image.

Taken with the Askar 120APO (review coming soon).

Bus on campus

Explanation of the stripes inside the bus.

This bus is electric!

Stripes made in Reading.

The new Reading 'warming stripes' double-decker electric bus came to campus today.

The bus is painted in the local warming stripes to start climate conversations throughout the town.

Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.

📸 This new NASA/ESA #Hubble Space Telescope image features the Cat’s Eye Nebula (NGC 6543).

Hubble’s sharp vision meets Euclid’s wide view to uncover this spectacular portrait of a dying star.

"quite a bit of the blame for this sad degradation of journalism, albeit absolutely not all of it, can be laid at the feet of the very same tech companies whose platforms destroyed the old journalism model, and who are now feverishly demanding that everyone shove LLM suppositories up their orifices.

How AI slop is causing a crisis in computer science Preprint repositories and conference organizers are having to counter a tide of ‘AI slop’ submissions.

Massive boom in conference submissions (chock full of AI fabrications) due to LLM adoption is NOT "increased researcher productivity"

It is research integrity failure, knowledge degradation, disciplinary suicide

This is why electrification means more energy security:

In 2024, ~81% of EU electricity came from locally sourced fuels (57% excluding nuclear). Just 19% relied on imported fossil fuels.

Fossil fuels are mostly imported.

Excellent summary.

“Legacy” code is *successful* code.

(I have minor quibbles with the Python and JavaScript mentions, but this is about COBOL.)

"A giant squid found at Ranheim in Trondheim 2 October 1954 is being measured by the Professors Erling Sivertsen and Svein Haftorn. The specimen was measured to a total length of 9.2 meters."

Let's talk about abyssal gigantism:
The tendency of animals found in ocean depths to be substantially LARGER than shallow-water cousins.

This is the giant squid (Architeuthis dux), which can reach 13 m (~40 feet) long from 'head' to tentacle tip.

They can live at depths of 1000+ m.

I hope that there will be a sequel.

Hydroclimate shapes photosynthetic sensitivity to cloud cover across global terrestrial ecosystems Nature Communications - Clouds affect photosynthesis differently across hydroclimates: they enhance it in arid regions but reduce it in humid regions. With climate warming, changes in cloud cover...

Clouds affect photosynthesis: they reduce sunlight but also supply rain. So are clouds good or bad for plants? New paper shows that it depends on water availability. Clouds will shrink in the warming future. That makes vegetation decline in arid regions and increase in humid regions. rdcu.be/e3TmT

A black-and-white portrait photograph of pioneering nuclear physicist Fay Ajzenberg-Selove, taken in her later career years. She is seated in a cozy, book-lined study or office, surrounded by shelves of books and framed photos on the wall behind her. She has short, neatly styled graying hair and warm, intelligent eyes, wears large, round-framed glasses that accentuate her thoughtful gaze. She has a gentle, knowing smile and is dressed in a patterned blouse or dress with a polka-dot or textured dark fabric, a small brooch or pin on her collar, and a simple necklace. Her hands rest calmly in front of her as she sits slightly turned toward the camera, exuding quiet confidence, resilience, and intellectual depth. The setting highlights her lifelong dedication to science, from her groundbreaking work on light nuclei spectroscopy to her influential compilations of nuclear data, and her advocacy for women in physics despite facing significant gender barriers in academia. The image captures her as a trailblazing figure who received the National Medal of Science in 2007 and left an enduring legacy in #nuclearphysics.

Nuclear physicist Fay Ajzenberg-Selove was born #OTD in 1926. She authored decades of authoritative compilations on light nuclei energy levels (researchers' "nuclear bible"). Recipient, National Medal of Science (US 2007) for advancing nuclear #physics. Advocate for #WomenInScience.

A satellite‑derived map showing accumulated rainfall over the Iberian Peninsula from 1 to 7 February 2026. Western Portugal and parts of northwestern Spain appear in deep red, indicating more than 250 millimetres of rainfall. Surrounding areas are shown in shades of blue, representing lower rainfall totals. Cities including Lisbon, Vigo, Madrid and Marbella are labelled. A legend at the bottom right displays rainfall values from 0 to over 250 millimetres.

A radar‑based comparison image of the Tagus River region in Portugal using Copernicus Sentinel‑1 data from 27 December 2025 and 7 February 2026. Flooded areas are highlighted in bright red, spreading along the river and its tributaries northeast of Lisbon. The surrounding landscape appears in grey‑blue tones. Coastal areas and inland terrain are clearly visible, with a scale bar indicating 10 kilometres and a date label in the lower right corner.

Three winter storms — Kristin, Leonardo and Marta — soaked the Iberian Peninsula in early 2026.
