It's hard to turn away from a picture of the Cat's Eye Nebula, even if you've seen it dozens of times. It may be the most visually compelling planetary nebula out there, with its billowing, layered shrouds and its intricate structure. NASA and the ESA have combined images of the Cat's Eye from the Euclid and Hubble space telescopes for a fresh look at a favourite and historical cosmic object.

Most coastal risk assessments have underestimated current sea levels, meaning tens of millions of people face losing their homes to rising waters earlier than expected

Andrew Doyle, the creator of both Jonathan Pie and Titania McGrath (both of whom some people still take seriously), has taken out after wokeness in the article below from his own site (free to access).  It contains 20 short but inadvertently funny videos documenting the “woke era”—an era that Doyle sees as circling the drain. (I wish!). Here’s his intro:

There is little doubt that historians of the future are going to look back on the ‘woke’ era with utter bafflement. How is it that intelligent people were suddenly caught up in this identity-obsessed hysteria? Why did they forget that free speech mattered? Or that human beings cannot change sex? Or that judging people by the colour of their skin rather than the content of their character was a bad thing?

The lunacy was so intense that these same historians will probably have to be persuaded that any of it happened at all. So I thought it would be helpful to compile some of the more ludicrous and shocking video clips from this recent culture war. A kind of digital time capsule, if you will, for the sceptics of the future.

Woke may not have ended, but with any luck we are over the worst of it. With that in mind, here are my top twenty snapshots of this bonkers period of our history. Enjoy!

Here are the 20 topics; I’ve put asterisks next to my favorites. Some of the topics include more than one video.  Do watch them all; it’s a good summary of how crazy things have gotten.

1.  The homophobic horses
2.  The no-no square*
3.  Gay conversion therapy goes mainstream
4.  The abolition of history
5. The alphabet soup (starring Justin Trudeau)
6. Queers for Palestine*
7. Problematic allies
8. “Progressive” racism
9. Pronoun lunacy, starring Kamala Harris and Jeremy Corbyn*
10. Student meltdown (the Christakis incident at Yale about the Halloween-costume fracas. It’s worth finding the whole thing on YouTube.)*
11.  You ain’t black
12.  Humza Yousef’s own goal
13.  Childhood indoctrination
14. Male breastfeeding*
15. Politicans forget about biology
16.  Thought police*
17.  Misogyny becomes “progressive”
18. Everyone is a Nazi*
19. Osama bin Laden gets some new fans (his “Letter to the American people” that the young wokesters so admired was removed from the Guardian, but can be seen here (and read about it here).
20.  The sancification of drag

I suppose my overall favorite is #2: the “no-no square”, described this way:

In Finland, Oulu city council established a €2.5 million project to address the rising cases of sexual assaults by migrants. It was called ‘Safe Oulu’, and this was the official dance.

This performative “dance” is supposed to reduce sexual assault, as if people don’t already know where are the parts that shouldn’t be touched.

 

The end-Permian extinction 252 million years ago wiped out over 80 per cent of marine species, but many ecosystems still had complex food webs despite the losses

Today’s Jesus and Mo strip, called “alps2” is “A resurrection. . . from 2008”.

And Mo is basically right on the etymology, at least according to this NPR site:

Cretin is a word derived from an 18th century Swiss-French word meaning “Christian.” The connection is basically pious, asserting that a mentally innocent person so-labeled is possessed of a Christian soul by way of baptism and is worthy of our mercy and pity.

As for “rug-butter,” I couldn’t find it but assume it is a derogatory reference to Muslims worshiping on prayer rugs, touching their heads to the ground.  But no, Jessus is not literally a cretin as he’s neither deformed nor hails from the Swiss Alps.  But I guess Mo literally butts rugs, though I’ve never seen him kneeling in prayer.

We have a few more batches in the queue now, but it’s never enough.

And today we’re featuring lovely bird photos from Ephraim Heller. I had no idea this gorgeous creature existed! Ephraim’s ID and captions are indented, and, as usual, you can enlarge the photos by clicking on them.

I never had a favorite bird. Oh, sure, I’ve seen plenty of bewitching bee-eaters, mesmerizing manakins and motmots and macaws, plummy pigeons, parrots and pheasants, and tangy toucans and tanagers, but they never held my attention.

In Trinidad I first met a tufted coquette (Lophornis ornatus):

My coquette is 6.6 centimeters (2.6 in) long and weighs just 2.3 grams (0.081 oz) – much smaller than my thumb! My coquette doesn’t eat at hummingbird feeders with the big boys – its bill is too short:

Its food is nectar, taken from a variety of flowers, and some small invertebrates. Across hummingbirds, specialization often involves bill length and curvature for particular flowers; my coquette is relatively unspecialized in bill morphology. My coquette often must sneak nectar from the territories of other hummingbirds. With its small size and steady flight, my coquette resembles a large bee as it moves from flower to flower:

Many hummingbird genera have territorial males, but the combination of extreme ornamentation, very small body size, and intense aggression is a hallmark of Lophornis.

There are 11 species in the genus Lophornis, all as beautiful as my coquette. The name Lophornis combines Greek for “crest” (lophos) and “bird” (ornis), calling out a shared trait of all the birds in this genus:

Per the Merriam-Webster dictionary, a coquette is “a woman who endeavors without sincere affection to gain the attention and admiration of men.” But I forgive my coquette. The females are more subdued than the males, but still marvelous:

In French my coquette is called “Coquette huppe-col,” which literally translates to “tufted collar coquette.” That sounds lovely in French. In German it is called “Schmuckelfe,” which combines the literal terms “jewelry or ornament” and “elf or fairy.” To my ear, “jeweled fairy” sounds more pleasant and less insulting than “schmuckelfe”:

Six years after the COVID-19 pandemic, which had claimed over 7 million lives worldwide by April 2024 (figures are no longer being tracked), we are still debating the origins of this novel virus. The intelligence community is divided between the zoonotic hypothesis (the virus evolved in animal reservoirs and then crossed over to humans) and the lab leak hypothesis. Essentially the consensus […]

An international team combining two major neutrino experiments has uncovered stronger evidence that neutrinos and antimatter don’t behave as perfect mirror images. That subtle difference may hold the key to why the universe didn’t vanish in a flash of self-destruction after the Big Bang.

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we’ve found so far - which in turn makes them interesting for astrobiological surveys. However, there’s a catch - astrobiologists aren’t sure the light from these stars can actually support oxygen-producing life. A new paper, available in pre-print on arXiv, by Giovanni Covone and Amedeo Balbi, suggests that they might not - when it comes to stellar light, quality is just as important as quantity. And according to their calculations, Earth-like biospheres are incredibly difficult to sustain around red dwarfs.

Panspermia is the idea that life was spread from world to world somehow. New research shows that one type of Earthly extremophile can survive the extremely high pressure from asteroid impacts on Mars, be blasted into space, and maybe even survive the journey to Earth.

Choosing the right method for multimodal AI—systems that combine text, images, and more—has long been trial and error. Emory physicists created a unifying mathematical framework that shows many AI techniques rely on the same core idea: compress data while preserving what’s most predictive. Their “control knob” approach helps researchers design better algorithms, use less data, and avoid wasted computing power. The team believes it could pave the way for more accurate, efficient, and environmentally friendly AI.

Scientists at the University of Tokyo have captured something never seen before: a frame-by-frame view of how electron spins flip inside an antiferromagnet, a material once thought to be magnetically “invisible.” By firing ultrafast electrical pulses into a thin layer of manganese–tin and tracking the response with precisely timed flashes of light, the team uncovered two distinct switching mechanisms. One relies on heat generated by strong currents, while the other flips spins directly with minimal heating — a far more efficient process.

With a simple motion, a jack-in-the-box-like spring designed at NASA's Jet Propulsion Laboratory showed the potential of additive manufacturing, also known as 3D printing, to cut costs and complexity for futuristic space antennas. Called JPL Additive Compliant Canister (JACC), the spring deployed on the small commercial spacecraft Proteus Space's Mercury One on Feb. 3, 2026. An onboard camera captured a video of the spring popping out of its container as the spacecraft passed over the Pacific Ocean in low-Earth orbit.
