The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It is the second-highest-energy cosmic ray ever observed, carrying around 40 million times more energy than particles accelerated at the Large Hadron Collider. Such particles are exceedingly rare and thought to originate in some of the most extreme environments in the universe.

Five dietary patterns that involve eating lots of plants have been linked with living up to three years longer, even among people who are genetically predisposed to have a shorter life

I have been wondering about the question above for a while, as I’ve read quite a few novels lately that use the word “luncheon”, with seemingly no distinction between that word and “lunch”.  I was too lazy to look it up, but, typing it in the search box, I found this short (1.5-minute) YouTube explanation below:

The Oxford English Dictionary agrees (the first meaning is “A large chunk of something, esp. bread, cheese, or some other food; a thick slice, a hunk; = lunch“).  The relevant entry:

There you go. But I still would like to be able to invite a friend to a restaurant for an informal luncheon.  That’s not correct, but it’s fun to say. And, at any rate, I don’t think I’ve heard anyone say “luncheon” lately, even referring to a formal meal. And in fiction it’s used incorrectly all the time.

Here’s a new article in Nature (click on the title screenshot below to read it); it’s about the dearth of information about the safety of drugs used by pregnant women. Except, to Nature, they refer not to “women” but to “pregnant people,” for in the article, that is about the only term that refers to women who are pregnant.  “Women” is used almost exclusively when it’s in quotations from others.

Here’s my count:

“Pregnant people”:  Used 41 times
“Women”:  Used 5 times, 4 of them in quotes from others

Clearly some bowdlerization is going on here.

The sad part of this article is that it has a lesson worth reading—a dearth of knowledge about how many drugs affect pregnant women—but it’s annoyingly peppered with politically correct and annoying usages. For example:

The first usage of the “pp” term is in fact in the subtitle, which I’ve highlighted below (again, click the article to read it):

Here’s a screenshot with “pregnant people” highlighted. This is only a small sample of the article:

Need I say more? What this means is that Nature is clearly truckling to the language adopted by extreme gender activists, who consider trans-identified men as “women”.  Ergo, the words “pregnant women” are seen as offensive, because “women” include trans-idenfied men who can’t have babies. Voilà:  “pregnant people.” Also, as reader Coel says below, “The main problem is trans-IDing women, aka ‘trans men’, who, being women, can get pregnant, but who they regard as ‘men’. Hence ‘pregnant women’ would exclude them, and so amount to erasure of and thus genocide of those ‘trans men’ who are indeed pregnant.”

Here are the five uses of the word “women”, all but the last quotes from other authors (they can’t sanitize other people’s words):

 

Note that the last usage of woman, not in quotes, is required because they are referring to females who are not pregnant. But the journal still slipped up: they could have used “people with uteruses”, or, like The Lancet, “bodies with vaginas”:

Conclusion: Nature has been ideologically captured. But we already knew that, didn’t we?

The journal should be ashamed of itself.

Scientists may have stumbled across a network of vessels in the brain that helps clear out waste fluid – a discovery that could "represent a paradigm shift in our understanding of all neurodegenerative diseases"

Well, this is the last batch of photos I have, and it’s very sad that the tank is empty. Please send some in if you have them. Don’t make me beg!

Today we have photos of ducks—or rather, one female duck— rom Aussie reader Keira McKenzie in Perth. Keira’s captions are indented, and you can enlarge her photos by clicking on them.

Here is a series of photos I took of a lone Pacific Black Duck [Anas superciliosis] from this afternoon [Feb. 11] at the park. Since the islands in the ponds have been completely cleared of all vegetation (the western island) and all the undergrowth cleared from the eastern island (this is because of the devastation throughout Perth’s trees from the polyphagous shothole borer), moat of the waterbirds have left for areas where they can roost & nest. 

The photos are taken in Hyde Park, Perth, Western Australia, on a hot humid afternoon.

I am very fond of them. I rescued one when it flew into the electric wires on the other side of the road one night. I carried it back across the road and into the park, putting it near the water’s edge. It was a pond-smelling little bundle, seemed uninjured and was very calm, and waddled off into the water and sailed into the night.

What a beautiful hen! It makes me eager for Duck Season to arrive at Botany Pond. Keira also sent a picture of her cat:

I shall sign off with a pic of my little Baba (currently zooming around the place for no apparent reason) slothing in the armchair in the heat with one of her favourite toys (the other is a wombat).

The universe is a big place, and tracking down some of the more interesting parts of it is tricky. Some of the most interesting parts of it, at least from a physics perspective, are merging black holes, so scientists spend a lot of time trying to track those down. One of the most recent attempts to do so was published in The Astrophysical Journal Letters by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration. While they didn’t find any clear-cut evidence of continuous gravitational waves from merging black hole systems, they did manage to point out plenty of false alarms, and even disprove some myths about ones we thought actually existed.

Eclipse season is nigh. The first of two eclipse seasons for 2026 kicks off next week on Tuesday, February 17th, with an annular solar eclipse. And while solar eclipses often inspire viewers to journey to the ends of the Earth in order to stand in the shadow of the Moon, this one occurs over a truly remote stretch of the world, in Antarctica.

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, the dying star blasts twin beams of light through a polar opening, carving glowing lobes and delicate ripples into the surrounding cloud. These striking, symmetrical arcs hint that unseen companion stars may be shaping the spectacle from within.

As data keeps exploding worldwide, scientists are racing to pack more information into smaller and smaller spaces — and a team at the University of Stuttgart may have just unlocked a powerful new trick. By slightly twisting ultra-thin layers of a magnetic material called chromium iodide, researchers created an entirely new magnetic state that hosts tiny, stable structures known as skyrmions — some of the smallest and toughest information carriers ever observed.

Ancient trees hold secrets about the most violent storms our Sun has ever unleashed, catastrophic bursts of radiation that dwarf anything modern civilisation has experienced. Scientists have discovered radioactive carbon signatures frozen in tree rings from solar storms so powerful they could cripple our satellite networks and power grids today.

Scientists at HKUST have unveiled a major leap forward in calcium-ion battery technology, potentially opening the door to safer, more sustainable energy storage for everything from renewable power grids to electric vehicles. By designing a novel quasi-solid-state electrolyte made from redox-active covalent organic frameworks, the team solved long-standing issues that have held calcium batteries back—namely poor ion transport and limited stability.

Dust from asteroid Bennu is revealing a surprising origin story for life’s building blocks. New research suggests some amino acids formed in frozen ice exposed to radiation, not warm liquid water as scientists long believed. Isotopic clues show Bennu’s chemistry differs sharply from well-studied meteorites, pointing to multiple pathways for creating life’s ingredients.

Scientists have uncovered evidence of a massive underground lava tube hidden beneath the surface of Venus, revealing a new layer of the planet’s volcanic history. By reexamining radar data from NASA’s Magellan spacecraft, researchers identified what appears to be a huge empty conduit near the volcanic region Nyx Mons. The structure could be nearly a kilometer wide and extend for dozens of kilometers below the surface.
