It’s 2050 and you’re living on Venus. This might come as a surprise due to the planet’s crushing surface pressures (~92 times of Earth) and searing surface temperatures (~465 degrees Celsius/870 degrees Fahrenheit), which is equivalent to ~900 meters (3,000 feet) underwater and hot enough to melt lead, respectively. But you’re not living on the surface. Instead, you’re safe and sound inside a lava tube habitat scanning data from the latest orbiter images while sipping on some habitat-made espresso.

Solar flares are one of the most closely watched processes in solar physics. Partly that’s because they can prove hazardous both to life and equipment around Earth, and in extreme cases even on it. But also, it’s because of how interestingly complex they are. A new paper from Pradeep Chitta of the Max Planck Institute for Solar System Research and his co-authors, available in the latest edition of Astronomy & Astrophysics, uses data collected by ESA’s Solar Orbiter spacecraft to watch the formation process of a massive solar flare. They discovered the traditional model used to describe how solar flares form isn’t accurate, and they are better thought of as being caused by miniaturized “magnetic avalanches.”

A new study led by researchers from Aarhus University showed that amino acids spontaneously bond in space, producing peptides that are essential to life as we know it. Their findings suggest that the building blocks of life are far more common throughout space than previously thought, with implications for astrobiology and SETI.

Interval cancers are aggressive tumours that grow during the interval after someone has been screened for cancer and before they are screened again, and AI seems to be able to identify them at an early stage

Astronomers have solved a bit of a mystery that had them questioning whether one of the most extreme stars ever observed was about to explode. WOH G64, a massive red supergiant in the Large Magellanic Cloud, began behaving so strangely that researchers suspected it had evolved into a rare yellow hypergiant on the brink of supernova. But new observations from the Southern African Large Telescope reveal the star is still very much a red supergiant, yet still exhibiting strange behaviour.

NASA has completed its first major testing of nuclear reactor hardware for spacecraft propulsion in over 50 years, marking a crucial step toward faster, more capable deep space missions. Engineers at Marshall Space Flight Center conducted more than 100 ‘cold flow’ tests on a full scale reactor engineering development unit throughout 2025, gathering vital data on how propellant flows through the system under various conditions.

Finding Earth-like planets is the primary driver of exoplanet searches because as far as we know, they're the ones most likely to be habitable. Astronomers sifting through data from NASA's Kepler Space Telescope have found a remarkably Earth-like planet, but with one critical difference: it's as cold as Mars.

A reanalysis of twin data from Denmark and Sweden suggests that how long we live now depends roughly equally on the genes we inherit, and on where we live and what we do

This YouTube video hasn’t gotten many views since it was posted three months ago, but I like it. It also is telling in showing the age difference in how Jews react when asked to “act or talk like a; Jew”. Here are the YouTube notes:

Inspired by the viral “Like a Girl” campaign by Always, JITC (Jewish Institute for Television & Cinema) Hollywood Bureau’s new video challenges the entertainment industry’s harmful Jewish tropes by showing what being Jewish really looks like, through the voices of Jewish children.

They describe “acting like a Jew” not as being neurotic or greedy – depictions that we too often see on screen, but as living with kindness, compassion, justice, and a drive to make the world better.

Already praised by Mayim Bialik, Nancy Spielberg, and others, the video calls on Hollywood to portray Jewish pride, joy, and authenticity.

The older folks act out the stereotypes of a Jew (I love the guy who swigs Mylanta and the one with the cigar who controls the globe), while the younger people evince the actual principles of Judaism (I like the little girl who lights the candles). Go to the site that explains this video to learn more.

I think this video was deemed necessary because of the rise of antisemitism and the attendant stereotypes of Jews. For example, lots of people, including Young Turks moderator Ana Kasparian has said that the Israeli lobby controls the US (see this enlightening video showing Bill Maher vs. Kasparian).

The Milky Way's Galactic Center and Bulge are shrouded in thick dust and tightly-packed with stars. It's a tough region to observe, but the Nancy Gracy Roman Space Telescope is built for the task. Its Galactic Bulge Time-Domain Survey will find more than 100,000 exoplanets, along with stars, black holes, neutron stars, and even rogue planets.

Yesterday we were talking about Michael Shermer’s new book on Truth, but only insofar as I disagreed with his podcast characterization of free will.  Now, however, while promoting his book on the radio, Shermer encountered some misleading “progressivism” about sex from one of public radio’s most well-known announcers and on NPR’s biggest station: Brian Leher on WNYC in New York.  You can read about what happened by clicking on the sceenshot below at BROADview News. And below that you can hear the whole 35-minute interview of Shermer by Lehrer by clicking on the black screenshot and then on the “listen” arrow. You might want to start about halfway in (see below).

First, some excerpts from the article:

Like so many liberals, I grew up with NPR as my soundtrack: BJ Leiderman’s thumping theme songs in the background, or the soothing voice of the late great Susan Stamberg. I loved NPR.

It became difficult to listen to starting in 2016, as the mission changed from reporting to making sure that we all had the same opinion. Then, once Katie Herzog mentioned a game in which you turn NPR on at random times and see if they’re talking about race, NPR started to seem like a joke. But also: it wasn’t funny. It wasn’t funny when they reported on gender—because they often reported activist talking points about the medical interventions as facts, and labeled truths as disinformation.

We’ve seen shifts in other mainstream media outlets, even a kind of two-steps-forward, one-step-back movement in The New York Times’ reporting on gender. But NPR is more dug in than ever. I assume this is in reaction to the defunding of the Corporation for Public Broadcasting. To admit that they were so biased that they didn’t deserve public funding was to retire their pitch for more funding from listeners—although what they should have done was pivot, to do a better job and argue that they deserved the funding.

All this is background for what happened yesterday on WNYC, the most-listened-to public radio station in the country. Journalist Brian Lehrer has hosted a weekday news call-in show for some 35 years, and was widely admired as one of the best out there—fair-minded and willing to engage with different voices. Like many others in the media, he changed.

You can see the change when “Mabel” calls in at 16:23. Mabel apparently didn’t tell the call screener what she wanted to say on the air, because she actually got through to the broadcast.  Mabel then emphasized that there were two biological sexes and members of one cannot become members of the other. As you’ll hear, Lehrer pushed back, saying that biological sex can be changed through “transgender’ hormones and surgery. (Lehrer apoparently doesn’t know the difference between sex and gender.) More from the article:

Mabel likely didn’t tell the screener what she really wanted to say, because it started with how America is becoming a third-world country and complaints about the lack of affordable housing. But then she said “The Democratic Party has let me down,” because they’ve also been untruthful. “Now they’re saying that men can become women and I feel that you are just discounting women as a species,” she said. Dems were “trying to make us believe that you can turn a male into a female.” She added that women were more than their anatomy; they were also shaped by their experiences.

That last part allowed Lehrer to make his case that “trans women would say they had their experience of being a woman before they had any hormone replacement therapy or surgery.” Amazingly, he added: “Maybe you’re just biased against a segment of society who you don’t like.”

Actually, you don’t have the experience of being a woman before you transition; you have the feeling that you are a woman and want to change aspects of your body to conform to that. More:

This was absolutely shocking—to hear Brian Lehrer, the former Voice of Reason, tell a caller that because she feels lied to about this issue she’s hateful was astonishing, and just incredibly unprofessional.

Shermer, on the other hand, handled it like a champ. He went into the difference between subjective truths—I feel like I was born in the wrong body—and objective ones: we cannot change sex, which is binary and based on gametes. Shermer said he worried about the future of the Democratic Party because it cannot distinguish between objective and subjective truths.

Lehrer himself seemed to be in shock, having hermetically sealed his studio to protect against any facts that interrupted the narrative he’d constructed. “This is what the right wing says, that it’s gender ideology,” he retorted. WNYC has worked hard to exclude liberal dissident voices, which has allowed them to maintain that left/right framing.

But Shermer pushed on. He explained the difference between the vanishingly rare occurrence of childhood-onset gender dysphoria and rapid-onset, the theory of social contagion, the poor evidence base, the shift in several European countries. “The facts matter,” he said.

Lehrer: “It sounds like you’re being very dismissive.” He said doctors would disagree that you can’t change sex, or that sex is binary. And finally, when Shermer came back with reasonable answers, Lehrer said: “You’re here supposedly representing science.” That is: Lehrer believed Shermer had lost all credibility by applying the same lens to youth gender medicine that he applied to everything else.

Most shocking about this whole exchange was what happened after it ended. Lehrer invited people who were offended to call in. After Shermer was gone! “Equal time,” he said—as if they’d ever given a minute to any of us wanting to share another side of the story.

And so, the parents and grandparents and uncles of trans kids rang up. . . .

Shermer did handle it like a champ, acknowledging that biology is binary but gender is an “internal, subjective state.”   If you want to just hear the relevant exchange, start the podcast at 16:23.

At the end of the piece, author Lisa Davis gives the emails of the segment’s producers in case readers or listeners want to write them, but you can go to the site above and complain if you wish. Regardless, Lehrer shows how fully NPR has bought into the theory that humans can change from one sex into another. Shermer does a great job correcting Lehrer, emphasizing that gender is an internal, subjective state and, as far as biological sex goes, we are not clownfish: humans can’t change from one sex to another.

"The worst thing about lockdowns is that they are over, and everyone else moved on long ago."

The post Science Based Satire:  My 2026 Interview with Jay Bhattacharya. It’s Still Lockdowns All the Way Down. first appeared on Science-Based Medicine.

Reader EdwardM has sent us some travel photos from Sri Lanka.  His captions are indented, and you can click on the photos to enlarge them.

These photos are of statuary and frescoes in the Dambulla Cave Temples outside Kandy, Sri Lanka. Kandy, by the way, has a venerated shrine which holds one of Buddha’s teeth! The Dambulla Cave Temples date to the first century AD. The caves, which sit high on a bare rock escarpment, were used as a refuge for a king, called Valagamba, and his people during one of the many invasions of Sri Lanka. To commemorate their survival, Valagamba and heirs founded a monastery in the caves. Over the centuries images, frescoes, and statues of the Lord Buddha, the bodhisattvas, and various gods and goddesses were installed. Typically they were funded by wealthy Sri Lankans for their private redemptive purposes, much like many Christian sites were funded by the wealthy in hopes of favor or forgiveness. The caves are full of these wonderfully vibrant icons.

The caves themselves were welcoming, with soft light and wonderfully cool air; a respite from the brutal Sri Lankan midday heat. One note I’d like to add. Sri Lanka is a fabulously beautiful land, and I know it has had a complex past with much turmoil and violence. But I became endeared to the people; they are delightful and they get genuine pleasure from other people’s happiness. They aren’t faking it. I loved the country, the people, and I encourage anyone who can go; visit.

Here are a few of the shots from the complex. There are five caves but two of them we closed for work when we were there. First, a reclining Buddha with statues of minor gods and goddesses at his head and one of the bodhisattvas (I have no idea which) seated at left. The Buddha was carved out of the rock in the cave. There are several of these at Dambulla.

This image gives an idea of the size of this reclining Buddha. This one is not the largest in the complex. Amazing that this is carved from the rock itself:

 

Some more statuary. These are depictions of the bodhisattvas, the enlightened followers of Buddha. Unlike the reclining Buddhas, most of the statuary was NOT carved from the rock of the cave, but was instead carved outside the caves and installed within:

The monks (it’s an active monastery) place offerings to various gods and goddesses. Here they put these fabrics on statues of a couple of the Enlightened, but I don’t recall the significance:

More shots of statuary:

The walls and ceilings were covered in beautiful frescoes, some ancient. Here are a few shots:

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Adults with kidney cancer who received faecal microbiota transplants on top of their existing drugs did better than those who had placebo transplants as their add-on intervention

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct

Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into formic acid, which is used in energy and manufacturing. The system even functions at CO2 levels found in normal air.

Jupiter’s atmosphere and clouds have mesmerized stargazers for centuries, as their multi-colored, swirling layers can easily be viewed from powerful telescopes on Earth. However, NASA’s Juno spacecraft has upped the ante regarding our understanding of Jupiter’s atmospheric features, having revealed them in breathtaking detail. This includes images of massive lightning storms, clouds swallowing clouds, polar vortices, and powerful jet streams. Yet, despite its beauty and wonder, scientists are still puzzled about the processes occurring deep inside Jupiter’s atmosphere that result in these incredible features.

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the Universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a Program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the Universe's expansion history that are twice as tight as past analyses.
