Why Evolution is True Feed - Fri, 01/16/2026 - 6:15am

Well, folks, we’re plumb out of readers’ contributions, and it makes me weep bitterly that we get so few contributions.  If you have good photos, you know what to do.

Fortunately, I am able to plunder the photos of Scott Ritchie from Cairns, Australia, whose Facebook page is here. (Thanks to Scott for his kind permission to repost.) I’m adding the second installment of Scott’s favorite photos of 2025; his first installment is here. His captions and IDs are indented, and you can enlarge the photos by clicking on them.

Here are some of my favourite pics from 2025. It was a big year, with trips to Florida, Costa Rica, Western Australia and Victoria/NSW. And I had a publication in Australia Birdlife showcasing the lovely Rainbow Bee-eaters at a local cemetery https://www.calameo.com/read/004107895fe9d41dc697d…. I hope you enjoy them.  Have a happy New Year all!

 

Latin America is a home of hummingbirds. Hear a Green-breasted Mango [Anthracothorax prevostii] feeds on a torch ginger. I just love the bright colors that do remind me of a mango:

Another lovely hummer, the fiery throated hummingbird [Panterpe insignis]:

Not all hummingbirds are colorful. But I just love the pose of this Long-billed Hermit [Phaethornis longirostris] as it came in to feed the torch ginger:

Costa Rica has many colorful songbirds. People think tanagers and warblers. This bird is a Golden-browed Chlorophonia [Chlorophonia callophrys],  You gotta love bird names:

This Ornate Hawk-eagle [Spizaetus ornatus] caused quite a stir among the twitchers at our lodge. You can see why, it’s quite an amazing bird:

Another truly magnificent bird was the King Vulture [Sarcoramphus papa], coming into land and feed on your corpse:

Back to far north Queensland. I got this Gray Plover [Pluvialis squatarola] in flight as he shook himself off after a refreshing bath: [JAC: Do enlarge this one!]

Double-eyed Fig-parrots [Cyclopsitta diophthalma] are one of my favorite birds. And green ants are one of my most despised insects. I think the fig parrot would agree:

Here’s a stampede of Chestnut-breasted Mannikins [Lonchura castaneothorax]. I call this a WTF moment, as a bird in the middle got caught a bit off guard:

A Great Egret [Ardea alba], enjoying a prawn for breakie. Cairns Esplanade:

We get many shorebirds to the Cairns Esplanade foreshore in our summer. Before they head back to Russia, China, Japan, even Alaska, they color up into their breeding plumage, and hope to attract a mate. These two Bar-tailed Godwits [Limosa lapponica] are coloring up very nicely:

“Will you play ball with me?” Nordmann’s Greenshank [Tringa guttifer], a.k.a. Nordy, is a very rare bird that has visited Cairns for six years running. He’s the only one of his kind here. I often wonder if he’s a bit lonely:

Why Evolution is True Feed - Fri, 01/16/2026 - 4:45am

Welcome to the end of the a frigid week in Chicago: it’s Friday, January 16, 2026, and National Fig Newton Day. Called “fig rolls” in the UK, the most famous U.S. version is from Nabisco, which has trademarked the name. Here’s some Fig Newton Trivia from Wikipedia:

In the 1939 promotional short Mickey’s Surprise Party, produced by Walt Disney for Nabisco’s exhibit at that year’s World’s FairMickey Mouse proclaims the Fig Newton to be his favorite cookie.

And here’s the cartoon (“produced for the National Biscuit Company”).  The Fig Newton bit appears at 4:52, saving the day after Minnie burns her homemade cookies, which are accidentally mixed with popcorn.

It’s also International Hot and Spicy Food Day, National Quinoa Day, and Religious Freedom Day.

Readers are welcome to mark notable events, births, or deaths on this day by consulting the January 16 Wikipedia page.

Da Nooz:

*If Trump continues to go after Greenland, he’ll be called a Nazi even more often, as he seems to be seeking Lebensraum.  And yes, Trump appears to be serious about acquiring Greenland. But the Greenlanders and Denmark aren’t having it. (Article is archived here.)n First from the NYT:

But if President Trump gets his way and, as he has insisted, takes over Greenland “whether they like it or not,” it would be bigger than any of those [California, the Louisana Purchase and other territories acquired by conquest or purchase], according to the National Archives, the U.S. census and the C.I.A. World Factbook. At 836,000 square miles, Greenland is bigger than France, Britain, Spain, Italy and Germany — combined. It would be the largest territory the United States ever added, if the United States were to acquire it.

Mr. Trump has based his fixation on Greenland, which has been part of the Danish Kingdom for more than 300 years, on reasons of “national security,” citing threats from Russia and China. But he made a past remark about Greenland’s size, and scholars say the territorial grandeur itself is at least part of what appeals to him.

“Trump’s a real estate guy,” David Silbey, a historian at Cornell University, said in an email, “and the idea of grabbing that much land seems to me his particular guiding force: THE MOST LAND EVER.”

He added that Mr. Trump “likes to pick on targets that are too weak to fight back, which certainly describes Denmark,” he added.

This week, Secretary of State Marco Rubio is meeting to discuss the future of Greenland with Danish and Greenlandic officials, both of whom say that the island, the world’s largest, is not for sale.

But that has not deterred Mr. Trump and his team so far.

In an interview last week with The New York Times, Mr. Trump said the best way for the United States to handle Greenland would be to own it because ownership is “psychologically needed for success.”

But, from the WaPo:

Denmark’s foreign minister said there had been a “frank but also constructive” conversation with the Trump administration during a high-stakes White House meeting about the fate of Greenland on Wednesday, but that the two sides had come to no agreement about President Donald Trump’s demands to “own” the Arctic territor

“We still have a fundamental disagreement,” said Lars Lokke Rasmussen, the top Danish diplomat, speaking alongside his Greenlandic counterpart, Vivian Motzfeldt, outside the Danish Embassy in Washington. “We didn’t manage to change the American position.”

The White House meeting, which was hosted by Vice President JD Vance, did see the two sides agree to form a “high-level working group” to discuss Trump’s concerns about Greenland, Rasmussen said. The White House and State Department did not immediately provide their own readout of the meeting, which was also attended by Secretary of State Marco Rubio.

Trump told reporters after the meeting that he had not yet been briefed on the talks, but said that the United States had a good relationship with Denmark and he thought something would work out. “The problem is there’s not a thing that Denmark can do about it if Russia or China wants to occupy Greenland, but there’s everything we can do,” he said in the Oval Office.

This is the craziest thing that Trump’s tried to do, and that’s saying a lot. We already have a base in northern Greenland, and perhaps they’d let us build another one. But the hubris of trying to take over what is essentially part of Denmark, the EU, and NATO is breathtaking. It sound like some nutty idea that Trump had in the middle of the night, but he’s trying to make it come true. I’m betting he won’t.

*David Plouffe argues in today’s NYT that “To win everywhere, Democrats must change everything” (op-ed archived here).

. . . to win races in politically unforgiving, even hostile, territory will require the party to overhaul its broken brand and stale agenda by elevating new faces and new leaders who promise to chart a course enough voters believe in.

Why? Because to have any hope of fixing the root problems that plague our democracy and our economy, Democrats need a majority that lasts, like the New Deal coalition. At least three, maybe more, Supreme Court justices could retire over the coming decade. Without sustained Democratic political power and control during that period, a conservative 8-to-1 court is not out of the question.

That possibility should focus the mind. Right now, Democrats have no credible path to sustained control of the Senate and the White House. After the adjustments to the Electoral College map that look likely to come with the next census, the Democratic presidential nominee could win all states won by Kamala Harris plus the blue wall of Michigan, Pennsylvania and Wisconsin and still fall short of the 270 electoral votes needed to win. An already unforgiving map gets more so, equally so in the Senate.

His solutions? (condensed):

The existential question now is: How do Democrats get back to playing and winning in more places?

First, make our unpopular president and his vassals own everything — higher energy and health care costs, higher food bills, war. The Republicans in Congress stood by meekly as Mr. Trump took a wrecking ball to our economy. They deserve the blame for it.

That is Task 1. As important as it is, it’s far easier than Task 2. James Baldwin wrote, “Not everything that is faced can be changed, but nothing can be changed until it’s faced.” Democrats must face, honestly, where we are and how we are perceived.

That starts with offering a fresh agenda that voters believe can make a difference in their lives, not the same stuff they heard from Democratic candidates in recent years.

Each candidate is different. That said, the ideas below should find a home almost anywhere.

Here’s a list (bolding is theirs):

A plan to bring down costs. ‘

A plan to create the jobs America needs.

A plan for A.I.  [Plouffe thinks it will play a big role in the next elections]

A plan for reform.

Hold your own leaders to account.

You can see all the details in the archived account. That’s a lot of plans, and yes, if most of that stuff can be conveyed to the people (Plouffe uses Mamdani as an example), the Dems’ chances will improve. But as you know, Mamdani was short on details, and can you imagine a Democratic candidate trying to explain to Americans how they would reduce any pernicious effects of A. I.? Well, as someone said, “All this is as plausible as anything else.” There is no shortage of people telling the Democratic Party what to do, but is anyone listening?

*The WSJ reports that the protests in Iran may have quieted down, which of course will impede Trump from carrying out his threat to attack with the aim of toppling the regime.

A fierce crackdown by Iranian security forces that has killed thousands of people protesting against the country’s autocratic leaders has forced demonstrators off the streets in some cities, with residents reporting an eerie quiet after days of escalating violence.

Iran’s government has blocked the internet and deployed large numbers of police and troops in an effort to quell the biggest threat to the regime since a 1979 revolution that established theocratic rule overseen by Shiite clergy. Iranians said they were afraid to leave their homes.

President Trump on Wednesday said Iran had stopped killing people, after days of threatening to take action against the regime if it killed protesters. Asked if military action was off the table, he said, “We’re going to watch it and see what the process is, but we were given a very good statement by people that are aware of what’s going on.”

The number of new protests verified by Human Rights Activists in Iran dropped to zero for the first time on Tuesday and continued at zero on Wednesday, the rights group said. It acknowledged that this could be because of the severe communications restrictions, which include disruptions to phone service.

The group said it confirmed the deaths of more than 2,600 people and more than 18,000 arrests. European and Middle Eastern officials also said they were seeing a drop in protest activity.

“The reason is very clear: The regime has created a bloodbath. They brought down the iron fist without precedent,” said Ali Vaez, an Iran analyst at the International Crisis Group. “That creates a chilling effect among protesters.”

Iran signaled Wednesday it was preparing to conduct swift trials and the execution of antigovernment protesters. In a video released by Iranian state television, Iran’s judiciary chief said on Wednesday the courts should act quickly against protesters.

The quiet is likely temporary, analysts said, since the underlying anger against the state remains high and the government has few ways to resolve the economic problems at the root of widespread discontent.

“Even if the first round is done, the next round is around the corner, because the regime is unable and incapable of addressing legitimate grievances,” Vaez said.

Some rumors say that cops with rifles are stationed on every street corner in Tehran, ready to shoot anybody who even vaguely looks like a protestor. We can’t expect people to keep protesting if they’re going to be shot willy nilly.  I am torn about this, as I do want the regime gone, but not necessarily with American military intervention. On the other hand, nonmilitary intervention doesn’t seem to be working. I fully expected an American attack, but without one, things will go back to the way they were, though I’m hoping, as the piece says above, that “the quiet is likely temporary.” For the moment it looks like the score is Regime 1, Protestors 0.

*More Trump-o-centric news: the “President’ has threatened to quash the protests in Minnesota not only by sending in more troops, but by invoking the Insurrection Act.

 President Donald Trump on Thursday threatened to invoke an 1807 law and deploy troops to quell persistent protests against the federal officers sent to Minneapolis to enforce his administration’s massive immigration crackdown.

The threat comes a day after a man was shot and wounded by an immigration officer who had been attacked with a shovel and broom handle. That shooting further heightened the fear and anger that has radiated across the city since an Immigration and Customs Enforcement agent fatally shot Renee Good in the head.

Trump has repeatedly threatened to invoke the Insurrection Act, a rarely used federal law, to deploy the U.S. military or federalize the National Guard for domestic law enforcement, over the objections of state governors.

“If the corrupt politicians of Minnesota don’t obey the law and stop the professional agitators and insurrectionists from attacking the Patriots of I.C.E., who are only trying to do their job, I will institute the INSURRECTION ACT, which many Presidents have done before me, and quickly put an end to the travesty that is taking place in that once great State,” Trump said in social media post.

Presidents have indeed invoked the law more than two dozen times, most recently in 1992 by President George H.W. Bush to end unrest in Los Angeles. In that instance, local authorities had asked for the assistance.

The Insurrection Act is old (from 1807), and says this:

The Insurrection Act authorizes the president to deploy military forces inside the United States to suppress rebellion or domestic violence or to enforce the law in certain situations. The statute implements Congress’s authority under the Constitution to “provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions.” It is the primary exception to the Posse Comitatus Act, under which federal military forces are generally barred from participating in civilian law enforcement activities.’

Normally the military, including the National Guard, is not empowered to enforce civil laws, but the Act allows them to. And the Act allows them to do this even against the wishes of the state.  ICE, however, is not the military, so once again we see Trump trying to use the military to quash civilian dissent, calling it an “insurrection”. It’s been used about 30 times, most notably to enforce civil rights laws in the Sixties. But if it’s used now to supplement ICE with the military (who of course aren’t trained in law enforcement), it will only exacerbate tensions. It may quell protests, but at a steep price.

The NYT is all about the ICE attack, the shooting, and immigration. Here’s this morning’s front page:

*And things are so bad that I’m adding the last Nooz post as the equivalent of the “there’s good news tonight” segment of NBC’s Evening News. Here’s the good news from the UPI:

 Police responded to a retirement home in Washington on a report of a goat attempting to break into the facility.

The Auburn Police Department said on social media that officers arrived at Wesley Homes to find “a goat was attempting to gain entry into the building.”

The officers “safely ‘detained’ the suspect until a friend of the owner arrived to pick her up,” the post said.

The goat, named Ruby, posed for a photo with the officers before being taken home.

“Charges were dropped due to extreme adorableness,” police wrote.

Here’s Ruby the perp and the cops:

How Astronauts Will Fix Their Gear Using Thin Air

Universe Today Feed - Fri, 01/16/2026 - 4:43am

Additive Manufacturing, more commonly known as 3D printing, will be an absolutely critical technology for any long-term settlement on another world. Its ability to take a generic input, such as plastic strips or metal powder, and turn it into any shape of tool an astronaut will need is an absolute game changer. But the chemistry behind these technologies is complicated, and their applications are extremely varied, ranging from creating bricks for settlements to plastics for everything from cups to toothbrush holders. A new paper available in pre-print on arXiv from Zane Mebruer and Wan Shou of the University of Arkansas, explores one specific aspect of a particularly important type of 3D printing, and realized that they could save millions of dollars on Mars missions by simply using the planet’s atmosphere to help print metal parts.

Red Dwarfs Are Too Dim To Generate Complex Life

Universe Today Feed - Thu, 01/15/2026 - 12:55pm

New research shows that complex life is unlikely to ever exist around cool, dim red dwarfs. About 33% of the Milky Way's stars are late M dwarfs, which are the smallest, coolest stars, and are the easiest stars to detect Earth-like planets around. The stars aren't bright enough for photosynthetic organisms to create a Great Oxygenation Event, which led to complex animal life here on Earth.

How Dark Asteroids Die

Readers’ wildlife photos

Why Evolution is True Feed - Thu, 01/15/2026 - 6:16am

We’re saved again, for one day, as reader Rodney Graetz from Canberra has sent in some lovely photos from a remote corner of Australia. Rodney’s captions are indented, and you can enlarge his photos by clicking on them. The three borrowed images are, I’m told, in the public domain.

Here is a series of landscape photos from a tourist boat journey along the Kimberley coastline from Darwin (Northern Territory) to Broome (Western Australia).  The distance, as the crow flies, was 1110 km (690 mi) but by hugging the coastline, the unrecorded distance was likely doubled.  We made land visits on 10 of the 12-day journey:

Our starting point, the Darwin coastline, is lapped by the Timor Sea.  It is shallow and muddy, in contrast to our Broome destination.  Like Broome, Darwin was targeted and bombed by the Japanese in February 1942.  Today, among the lush Darwin city coastline gardens, is a simple memorial honouring the 91 crew of the USS Peary, the United States Navy’s greatest loss in Australian waters.

Departing Darwin, we slowly merged with the mighty Indian Ocean whose colour and cloud streets suggested warmth, productivity and excitement.  We travelled in early June, too early to encounter the estimated 40,000 Humpback Whales travelling up from the Antarctic (June – November) to calve, nurse and then mate in these warm and safe waters  Next time!

At last, an edge of the NW corner of the Australian continent, revealing a flat and layered landscape.  The cliffs are massive, and the rock type is obviously hard because there is little sandy beach.

The Edge close up, and as predicted.  Note the tiny figures in the lower left corner.  The massive rocks are a hard Paleoproterozoic sandstone aged 1-1.9 billion years.  They are ever varied and spectacular:

Being drone-deficient, I’ve borrowed this image to illustrate this monsoonal landscape functioning.  During ‘The Wet’ (Nov–Mar), sufficient rainfall accumulates on the background plateau for a flow to eventually reach the edge and fall as spectacular waterfalls early in ‘The Dry’ ( Mar-Nov).

Downstream from the waterfalls, slow moving water combined with the incursion of plants, result in species-rich landscapes, such as this small idyllic wetland:

‘Salties’, aka Saltwater crocodile, were common neighbours at our landings.  Maneaters?  Yes, but only of the deserving at a rate of fewer than one person per year.  The ‘gaping’ is not a threat display but thermoregulation, of cooling.  Looking past the teeth, they are handsomely ornamented and coloured animals.  In the water, they are sleek!:

For geographic and celestial reasons, the tidal ranges along this coast are among the highest globally (± 10 metres).  A consequence of this, and a rocky, indented coastline, is the creation of Horizontal Waterfalls, where six times a day, huge volumes of water are forced through constricting narrows, as shown here.  Spectacular and hazardous:

The edge of a vast inshore reef (400 km², 154 sq mi) rapidly shedding water as the tide drops about 10 metres.  It is a visual and turbulent spectacle – the reef appears to rise up – and shed streams of water containing stranded fish eagerly sought by waiting birds, fish and sharks.  This one image could not capture the turbulence and action.  Details are here and an overview here:

Contemplative natural beauty of the coast was commonplace, such as here, Raft Point.  With the Dawn behind us, the red rocks and lush vegetation (including iconic Boab trees) are in contrast with the ocean, and on its horizon, small red rocky islands urge a visit:

Nearby Steep Island is another view that repays contemplation.  Why is it so?:

Journey’s end and Broome colouring contrasts with that of the previous days.  Here the rock and sands are red with an aquamarine ocean.  Tidal variation remains high.  The biological focal point is the adjacent Roebuck Bay, the background in this image:

To avoid lethal winters, some 100, 000 migratory birds fly from the Pacific low latitude coastal areas of China etc. to Australia along the East Asian-Australasian Flyway.  Roebuck Bay, a primary destination, is nationally protected as one RAMSAR wetland.  Bird lovers closely watch their comings and goings:

Finally, in the 1940s, both Darwin and Broome experienced the destructive impacts of war.  Now, in both locations, the stark remnants of those impacts remain submerged, slowly disappearing, accelerated by the living world.  That is a good thing:
