New research presents a timeline for recent (astronomically speaking) events in the Saturnian system. It shows that Titan collided with a proto-Hyperion, and the collision smoothed Titan's surface while some of the debris accreted onto a new Hyperion and also created Saturn's rings. The research can also explain some of the Saturnian system's other unusual characteristics.

A technology that uses a coiled wire to electrify aerosols has boosted snowfall amid a drought in the western US, according to the company developing it, but the results haven't convinced other scientists

An ultrastable laser could enable extremely precise timing and navigation on the moon, and the cold, dark craters near the lunar poles would be the ideal location for it

SpaceX founder Elon Musk now says he wants to build a city on the moon before building a city on Mars. Is either scenario realistic? In the latest episode of the Fiction Science podcast, biologist Scott Solomon, the author of a new book titled "Becoming Martian," does a reality check on humanity's prospects for living on other worlds.

The evolution of human hands is one of the most important – and overlooked – stories of our origin. Now, new fossil evidence is revealing their pivotal role

A giant virus encodes part of the protein-making toolkit of cells that gives it greater control over its amoeba host, raising questions about how it evolved and how such beings relate to living organisms

Results are coming out from the samples returned by China’s Chang’e-6 sample return mission to the far side of the Moon. They offer our first close-up look at the geology and history of the far side, and a recent paper published in Science Advances from researchers at the Chinese Academy of Sciences has very interesting insights about the impact history of the Moon itself, and even some for the solar system at large.

As I am out of photos, and readers are withholding theirs, I once again steal the lovely photos of Australian Scott Ritchie from Cairns, whose Facebook page is here. Scott’s captions and IDs are indented, and you can enlarge his photos by clicking on them. .

I went to Melbourne during the middle of January to visit friends. Of course, birds are my feathered friends. This report cover a visit to the WTP, Western Treatment Plant, at Werribee, Victoria. These names pass mythically from the lips of Australian birders. I’ve been there before and really enjoyed it, but this past trip was wild. WTP is a series of quite large, secondary sewage treatment ponds, and lagoons. These abut along the great Southern Ocean and you get this wonderful interaction of freshwater and saltwater wetlands and associated birds. These are used, particularly in our summer, as overwintering sites for migratory shorebirds. But there’s a lot of resident waterfowl and waders there too. The WTP is so valued that you have to have a key to the gate for access to the site. Fortunately, my friend David was a key-carrying twitcher.

The weather was crazy, with 45 KPH winds. One of the first things I discovered was that strong winds can really mess with a telephoto lens. My lens was being buffeted by the gusty, easterly winds to the point where I had to remove the lens hood to stabilise the camera. But a few interesting things happen because of the wind. It was a great opportunity for BIF shots; birds in flight. Birds generally take-off and land into the wind, and because it was so strong, they were moving quite slowly. So I got nice shots of normally very fast birds such as terns and sandpipers as they came into land. Attached are some fun pics.

The next day I did a short walk through Banyule Flats Reserve, an urban Melbourne wetland. The highlight was to see the oh so cute Owlet Nightjar, as well as a family of Tawny Frogmouths. Shout out to Lyn Easton for leading the tour.

A Black Swan Beach. The high winds packed the east facing beach with seagrass. And the Black Swans [Cygnus stratus] made for the buffet:

A beach of Blacks Swans, necks writhing like snakes:

Amazing!

“Ahh, now that feels good.” An Australian Spotted Crake [Porzana fluminea] enjoys the breeze up its bum:

“Bugger off!” But is not happy with the hordes of shore flies:

An immature Black-shouldered Kite [Elanus axillaris] gives us the eye:

Whiskered Terns [Chlidonias hybrida] cruised flew slowly against the wind, providing good views for the camera:

. . . and another:

A Black Kite [Milvus migrans] swings down to pick up a dead little bird that have been by a car:

A large flock of Australian shelducks [Tadorna tadornoides] into the WTP. It was great to see large numbers of waterfowl darken the skies:

I had fun shooting small short birds, as they say, coming into land against the wind at adjacent pool. This is a Rednecked Stint [Calidris ruficollis]:

And here comes a Sharp-tailed Sandpiper [Calidris acuminata]:

A family of Tawny Frogmouths [Podargus strigoides] greet the day at Banyule Flats Reserve:

But he poses stoically, “You can’t see me!”  Frogmouths sit still, imitating dead branches and stumps:

A bit of a loose feather gives him away:‘

 

An Owlet-Nightjar [Aegotheles sp.] peaks out of his hole hollow. He stared at all the photographers down below. We must’ve started him because then he just disappeared. But we waited and waited:

“Come on, take your pictures!” He suddenly popped up, posing nicely:

Using local resources will be key to any mission to either the Moon or Mars - in large part because of how expensive it is to bring those resources up from Earth to our newest outposts. But Mars in particular has one local resource that has long been thought of as a negative - perchlorates. These chemicals, which are toxic to almost all life, make up between 0.5-1% of Martian soil, and have long been thought to be a hindrance rather than a help to our colonization efforts for the new planet. But a new paper from researchers at the Indian Institute of Science and the University of Florida shows that, when making the bricks that will build the outpost, perchlorates actually help.

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our galaxy’s core. Pulsars act like incredibly precise cosmic clocks, and finding one in this extreme environment could open a rare window into how space-time behaves under intense gravity.

Hearing a sound while working on a complex puzzle, and then hearing it again during sleep, helped lucid dreamers better tackle the problem the next day

Enshittification, also known as crapification and platform decay, is a process in which two-sided online products and services decline in quality over time. As some of you may be aware, I was an Infectious Disease (ID) physician for almost 40 years, retiring 3 years ago. My practice was almost entirely concerned with taking care of patients in several acute care hospitals. So […]

The post MD Enshittification first appeared on Science-Based Medicine.

Quantum key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the transmitter and receiver aren’t perfectly aligned. Researchers have now taken a deep dive into this often-overlooked issue, building a powerful new analytical framework to understand how tiny beam misalignments—caused by vibrations, turbulence, or mechanical flaws—disrupt secure key generation.

According to the researchers from the University of Pennsylvania, some of the amino acids found in the asteroid Bennu likely formed in a different way than was previously thought, effectively challenging what we thought we knew about the origins of life.

A complex web of interrelated factors make Earth a life-supporting planet, and some of those factors are chemical. New research shows how oxygen abundance regulates the availability of the important chemicals phosphorous and nitrogen on planets, and that few planets get it right. While discouraging, it could help us optimize our search for habitable worlds.

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades

In this week’s news-and-snark piece, Bill Maher offers a piece that may be controversial, for it’s about how men need to be “men” again.  He avers that the loss of masculinity in males is one reason why women are disappointed in men, and why people are having less sex.  The data are eye-opening; for example, 44% of Gen Z men say they’ve had no relationship experience at all during their teen years.  That means up to age 20! And you might be interested in the new genre of literature he describes: “romantasy”, in which women get involved with animals or half-animals like centaurs.

His solution? Men should “man up”. His example: Taylor Swift being engaged to football star Travis Kelce (“old-school wood”) after writing songs about all the lame men she was once involved with. (He describes songs by other women.) Is he right?  I have no idea.

The Moon has a busy next two weeks ahead of it. Fresh off of Tuesday’s annular solar eclipse, the Moon begins an evening tour of the planets in the last half of February 2026. The waxing Moon actually slides by every planet except Mars over the next week. As a highlight, the waxing crescent Moon actually occults the planet Mercury in a rare celestial event on the night of Wednesday, February 18th.

The psychedelic DMT has been linked to improved mental health outcomes before, but now, scientists have shown it reduces depression symptoms more than a placebo when given alongside therapeutic support
