It’s out. The top sci-fi draw of the year Project Hail Mary is now showing in a theater near you. The movie tells the tale of middle school teacher Ryland Grace, who is sent on a one way, last ditch mission to save humanity. The story is a refreshing take on first contact and just how different life out there could be… but are there real ‘Adrians’ or ‘Erids’ out there? A new paper published in the Monthly Notices of the Royal Astronomical Society identifies 45 rocky worlds with a potential for life, out of the currently 6,281 exoplanets known.

Douglas Adams famously told us the answer to life, the universe and everything is 42. Astronomers have been wrestling with their own version of that answer for years, except their number is the Hubble constant, a measure of how fast the universe is expanding, and nobody can agree what it is. Now a new study using ripples in spacetime as a measuring tools has produced a fresh value that might just help resolve one of the biggest arguments in modern cosmology.

Look up on a clear night and you can spot the distinctive 'W' shape of Cassiopeia with the naked eye. The middle star of that W, which has the catchy name of Gamma Cas, has been puzzling astronomers since 1866, and for the last fifty years it's been blazing with peculiar high energy X-rays that simply shouldn't be there. Now, thanks to a next generation space telescope with extraordinary precision, the mystery has finally been solved. The culprit is a hungry invisible companion, quietly feeding in the dark.

In the absence of much of a backlog, I’ve stolen some gorgeous photos from reader Scott Ritchie of Cairns, Australia (his FB page is here).  Scott’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

Recently I visited my friends, Karen and David Young in the Crater Lake cabins near Lake Eacham, Atherton Tablelands, west of Cairns. This area is a mega for birds and they did not disappoint. In particular, we got great up close and personal views of our local bird of paradise, bird of prayer, paradise, the Victoria rifle bird.

The male of the species has jet black feathers. However, in just the right light you get a lovely iridescent reflection. The other thing these birds do is dance. It’s an amazing shuffling of the wings while top of stump while throwing their head out and flashing your lovely iridescent blue throat. The immature riflebird is a beautiful brown/rufous color, and they can’t help to practice their dance moves. And of course dad’s gotta come along and join in the festivities.

Also, here’s a few photos of some other creatures that I saw on my little five hour trip to the table lands. I hope you enjoy them.

Male Victoria’s Riflebird (Ptiloris victoriae),in full dance pose. Note the jet black feathers:

Swishes wings sideways, like a flying saucer. Peering above the wings:

But in the right light, iridescent rainbows appear:

I love the cooper and purple sheen on his back:

Meanwhile, youngster, an immature male, practices his dance moves. He leans back, showing off his wild yellow throat:

“Peek-a-boo”
Stands up, and swishes his wings back and forth, hiding his head behind them:

Then stands proud:

And then the adult male shows up. I’ll show you who’s boss:

Has he lost his mind?

I’m definitely King of the Stump:

Off youngster goes, only to be replaced by another male!:

And a few other local birds made an appearance. Pacific Emerald Dove (Chalcophaps longirostris):

Macleay’s Honeyeater (Xanthotis macleayanus):

Grey-headed Robin (Heteromyias cinereifrons):

And the musky rat-kangaroo (Hypsiprymnodon moschatus), our smallest proper roo!:

And the Boyd’s Forest Dragon (Lophosaurus boydii) appeared for the lizard and snake lovers:

Venus is increasingly becoming a touch point for our studies of the exoplanets, as missions like the James Webb Space Telescope (JWST)and the upcoming Habitable Worlds Observatory (HWO) begin to characterize rocky exoplanets around other stars. Understanding the difference between the evolutions of Venus and Earth, which ended up with such different results, is a key to understanding whether we might be looking at an Earth-analogue or a hellish landscape like Venus. A new paper by Rodolfo Garcia of the University of Washington and his colleagues, which is available in pre-print form on arXiv, simulates Venus’ 4.5 billion year evolution as part of the solar system to try to understand some of those differences.

Deepfake X-rays created by AI are now convincing enough to fool both doctors and AI models. In tests, radiologists had limited success identifying fake images, especially when they didn’t know they were being shown. This opens the door to risks like fraudulent medical claims and tampered diagnoses. Experts say stronger safeguards and detection tools are critical as the technology advances.

Astronomers have observed two planets forming in the disc around a young star named WISPIT 2. Having previously detected one planet, the team have now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique structure of the disc around the star, indicate that the WISPIT 2 system could resemble our young Solar System.

With the ISS set to retire in 2030, several plans are in place to replace it. These include existing space stations, proposals by rising national space agencies, and commercial space stations. In terms of the commercial space sector, the plans are diverse and numerous.

I’ve often criticized Colossal Biosciences for their overblown science, which includes pretending that they’ve resurrected the dire wolf (Aenocyon dirus), when they’ve only created grey wolves (Canis lupus) with a few gene edits that make them white (real dire wolves probably were not white!) and a bit larger. Three of these edited wolves have been released at a secret location, and Colossal has pronounced them to be dire wolves even though they’re they’re not dire wolves. In fact Colossal has admitted they haven’t “de-extincted” dire wolves—and yet they pretend otherwise. It’s a squirrelly business, but they need to keep attracting and keeping donors.

On tap: their promise to “de-extinct” the woolly mammoth, which will in fact not be a wooly mammoth but at best a hairy Asian elephant. And they say that they’ll get a population of these creatures going on the tundra within eight or so years.  I wouldn’t bet on it!

This morning I got an announcement that the three dire wolves in captivity have eaten an animal—a dead deer! Surprise!

Here’s the announcement:

Did you know most wolf hunts end in failure?  Wolves look like perfect hunters, but in the wild they actually fail nearly 9 out of 10 hunts. So how do they ever get good at it? In our latest video, narrated by Colossal’s Manager of Animal Husbandry Paige McNickle, we explore how wolves actually learn to hunt, and see the dire wolves Romulus and Remus face a messy milestone as they try to figure out how to skin, tear, crunch, and share a whole deer. Will the young dire wolves be successful? The answer might surprise you. When I said the whole thing was ridiculous, Matthew (another critic) responded, “Exactly. “Look, Homer, they are just like our pet dog!”
Note the videos showing a bunch of white “dire wolves” chasing buffalo. I don’t think that can be real, as they made only three dire wolve, and they aren’t penned in where the buffalos roam.Note as well that they are showing gray wolves, not dire wolves.  And of course they’ll eat a wolf carcass, for “dire wolves” are just tweaked gray wolves, and they are going to eat a deer carcass if they get it.  This deer was (I hope) killed before presented to these mutants.The YouTube notes.

Narrated by Paige McNickle, Colossal’s Manager of Animal Husbandry, this episode also gives you a close look at the continuing development of our young dire wolves, Romulus and Remus. They’ve already taken down small prey, and they’re continuing to learn the essential behaviors of being wolves. To help them develop more skills, the dire wolves are given a whole deer carcass. This is an important milestone in their development, as they learn how to skin, tear, crunch, and share a full prey animal.

This is undoubtedly meant to keep the public excited and, more important, keeping the donors satisfied and bringing more $$ in.  But what is the purpose showing these gray wolves learning to be gray wolves? They’ll never be released into the wild! I suppose you could say that this shows how gray wolves not born into a pack can learn various behaviors. But that has nothing to do with dire wolves.  To me it’s a big yawn in the service of Mammon.

And where is the third “dire wolf”—Khaleesi? Is she getting dog food somewhere?

Neptune has always been something of a puzzle. The distant ice giant sits tilted at an awkward angle, although not as extreme as Uranus, that astronomers have long struggled to explain. Now new research suggests the answer may have been lurking in its own backyard all along and the culprit is Triton, Neptune's strange, rebellious moon.
