Space is getting crowded - and not just with satellites, but with the massive amounts of data they’re generating. The amount of information being generated and passed through orbit is exploding. From high-resolution Earth observation images to global maritime monitoring, it’s also become a critical link in our infrastructure. But there’s another space this growing crowd of satellites is dependent on that is also filling up fast - the radio frequency spectrum. If we want to keep expanding our orbital infrastructure, we need to rethink how we move data around. On March 30, 2026, the European Space Agency (ESA) supported a series of eight CubeSats and one specialized payload on SpaceX’s Transporter-16 rideshare mission with the overarching goals of testing high-throughput laser communication, inter-satellite networking, and in-orbit artificial intelligence processing to make space data transfer faster, more secure, and vastly more efficient.

My insomnia continues, and has apparently worsened for reasons I don’t understand. Perhaps it’s anxiety about the war, but it’s definitely anxiety about something. Perhaps subliminal anxiety—after all, we can’t control what our brain does.  Last night I woke up at 2 a.m. and couldn’t get back to sleep. When this happens nearly every night, I try to suppress the worries that arise almost—like everyone, I have a panoply of items on the worry list. But anxiety seeps in and keeps me awake. AT 4 a.m., I hauled my sorry tuchus out of bed, did my ablutions, and came to work. That is the usual situation.

If I were to guess at the items that make me most anxious (besides the worry about getting back to sleep, which is counterproductive), there are these:

The Middle East.  Because I post daily about the war in Iran and other Middle Eastern matters, I seem to have gotten caught up in the roller coaster that is this region of the world, a roller coaster exacerbated by Trump’s waffling, which may be a deliberate strategy.  Regardless, like the mess that is American politics now, I realize that there’s little I can do to affect matters. And given that, I should simply observe the situation, express my opinion when I can, but not get so engaged that I’m destabilized by the ups and downs of both the war and politics.  But in this I’ve failed.

The ducks at Botany Pond.  I should just do what I can to take care of them, including feeding the ducklings when they come, but caring for them has almost become an obsession.  “No ducklings left behind” is my motto.  There’s nothing I can do to stave off most predators or prevent errant mallards from entering the pond and harassing Vashti, but somehow it’s a constant anxiety until the ducklings grow up and fly away.

Death.  I guess a lot of readers don’t worry about their mortality, but when you get into your seventies it’s almost inevitable. I’ve already lost several friends and classmates, and of course, as the syllogism goes, all men are mortal.

In response, some people have said that because they don’t worry about the time before they were born, which they equate with the time after they die, it’s futile to be afraid of death. In response to that I quote Christopher Hitchens, who knew he was dying of cancer but never openly admitted it:

“It will happen to all of us, that at some point you get tapped on the shoulder and told, not just that the party’s over, but slightly worse: the party’s going on — but you have to leave. And it’s going on without you. That’s the reflection that I think most upsets people about their demise.”

I once asked readers if they wanted to be immortal (with the stipulation that you don’t fall apart completely), and most said “no”—they will have seen enough of life when the Reaper comes. But I like the party too much!

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The effect doesn’t change how much light atoms emit, which is why it’s gone unnoticed until now. If confirmed, this approach could lead to ultra-compact detectors using cold-atom systems.

A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance—but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the superconductivity disappears at first and then dramatically reappears at even higher fields, earning it the nickname the “Lazarus phase.”

Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently. Using a novel imaging method, they revealed hidden structures acting like charge “highways.” This insight could unlock even more powerful, low-cost solar cells.

A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs. By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of traditional designs. The prototype achieved impressive efficiency and delivered much more power than previous attempts. Though not ready for widespread use yet, it points to a promising future for high-performance computing.

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce detectable signals.

Physicists have shown how time can effectively be reversed for some quantum systems, which would allow for new ways to harvest energy

The incompleteness theorem is accepted as part of the mathematical canon today, but columnist Jacob Aron says it was a bombshell when Kurt Gödel first introduced it. Gödel’s seminal work directly contradicted one of the great minds of mathematics and limited the field forever

Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help future searches for new particles

Every day they show up to work, with sweet declarations of love for Trump pouring from their lips, they are further reaffirming their decision to bind themselves to everything he does.

On August 19, 2022, astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and hydrogen-epsilon lines. It was the first time these two light signatures were seen in great detail during a flare. According to computer models, those lines were stronger than expected and play a not well-understood role in how flares heat the solar atmosphere where they occur.

The first flyby images of the Moon captured by NASA’s Artemis II astronauts during their historic test flight reveal some regions no human has seen, including a rare in-space solar eclipse. Released Tuesday, astronauts captured the images April 6 during the mission’s seven-hour flyby of the lunar far side, showing humanity’s return to the Moon’s […]

Observing the Taurus Molecular Cloud, a research team led by Kyushu University has found that during the early growth period of a baby star, the protostellar disk blows magnetic flux 1,000 au in size and creates a giant, relatively warm ring. Describing these phenomena as a baby star’s “sneezes,” these expulsions of energy and gas help the star to properly develop.

Researchers who observed a murderous conflict unfolding in a once-unified group of wild chimpanzees say there are parallels with civil wars in human societies

It was a rough morning on Botany Pond. Two undocumented drakes invaded this morning, and I must have spent 45 minutes chasing them around with my squirt gun. They would leave (along with Armon, who always returns), but then come back again. When they are around they will harass Vashti, even driving her off the nest, and that’s not good.

Finally Armon and Vashti were left alone, but I don’t want the undocumented ducks coming back.  Also, when chasing the errant drakes away, I accidentally spooked the wood duck pair, who have taken off.  I was sad because I love them so much, and I hope they return. (They’re clearly not yet nesting.) Armon goes after invaders, but not with great vigor: he’s a bit of a wuss.

But now all is quiet, and we had an epochal event a few minutes ago: four of the five red-eared slider turtles we put into the pond last fall (retrieved before Botany Pond was renovated) showed up, and all were competing for space and sun on a small rock.  There are other rocks they could use, but they like the one below.  I suspect the fifth turtle wandered away from the Pond at some point. This is the first time I’ve been able to see more than three turtles.

I’m exhausted: duck tending is no picnic!

As always, an Aussie who wishes to remain anonymous sent me this link, and noted that New Zealand isn’t the only country in the Antipodes that tries to make science (again “Western science”) coequal with indigenous knowledge.  Clicking on the screenshot below will take you to the strategy developed by the Aussie government: the “Australian Marine Science Strategy 2026-2036”

It begins on p. 2 with a land acknowledgement:

. . continues with a mission statement on page 4:

The National Marine Science Strategy 2026–36 sets out the research and development needed to realise the socioeconomic opportunities and benefits that come from enabling a thriving ocean economy while effectively minimising, mitigating and adapting to the critical challenges facing Australia’s ocean and coasts over the coming decade. It recognises that responding to challenges such as climate change and extreme events, biodiversity collapse and competing ocean uses will not only help ensure a healthy ocean, conservation and national resilience, but also unlock new opportunities for sustainable industries and innovation that deliver long-term environmental and economic prosperity for Australia.

. . . and then sets out seven “national ambitions” for improving our knowledge of marine science, all of which (save one) involve conservation, mitigating climate change, and fostering marine “industries.” The exception is the very first ambition:

Embed First Nations knowledge, innovation and leadership in marine science to ensure sustainable and equitable marine policy and management.

Finally, after going through the ambitions, continuously paying homage to the “knowledge systems” of the First Nations people (i.e., the Aboriginal Australians and Melanesian Torres Strait islanders), the report gives its recommendations. Here’s the very first recommendation (p. 33):

Now there’s nothing wrong with ensuring that the two groups that constitute the First Nations People get equal opportunity to do science and contribute to science. And insofar that the indigenous people have produced knowledge that can be verified by modern science, by all means give them credit and fold that knowledge into modern science. But, as usual, they do more than that. First the program argues, again with a dearth of examples, that “We also have much to learn from the integration and application of Indigenous knowledge systems and Western knowledge systems.” (p. 28). How do they know that? Where are the improvements in marine biology that have already come from “indigenous knowledge systems”?

This is not science or technology, but a drive for scientific equity: making indigenous knowledge coequal with modern science. And that is not even politics, but the sacralization of the oppressed. As we’ve seen so many times before from Canada and New Zealand, it is virtue signaling on a national scale.
