Science Week — #7

Ever wondered if your mind is something the brain builds, or if consciousness is woven into the fabric of reality like space and time? That was one of the big questions on the table this week — and it’s the kind of question that makes coffee taste stronger. Welcome to episode 7 of our weekly science roundup, the science of the week for August 25.

And we have a stacked set of stories: a philosophical dust-up about consciousness, new lab methods for building DNA at scale, a protein cookie born from plastic waste, a fresh look at the San Andreas Fault, an upcoming lunar eclipse, and two space notes from NASA — one new lunar crater image and one canceled rescue mission.

Life and brain to start, then health and biotech, then planet and climate, then up to space, then a methods-and-materials turn, and finally what it all adds up to. Let’s dive.

So, consciousness. A symposium in Porto, Portugal brought philosophers and scientists together to debate whether consciousness is emergent — something the brain constructs — or fundamental — something as basic as mass or charge. Neuroscientist Christof Koch argued for the bold option: that consciousness could be a basic property of reality. And he criticized materialist models as not really explaining subjective experience. That’s according to reporting from Yahoo.

It’s a lively debate, and to be clear: this is a philosophical and theoretical discussion, not new experimental data. No one announced a lab test that decides the issue. What we have is a high-level argument about frameworks.

Still, it matters. Even the way we pose research questions depends on whether we think consciousness is just brain machinery, or if we need to consider it as a primitive of nature. It shapes what we expect from brain scans, from neural networks, even from how we interpret anesthesia or sleep.

Right. And it’s also worth separating claims. Saying “materialist models fail to explain subjective experience” is a critique of current theories, not evidence that consciousness is fundamental. We’d need testable predictions that distinguish one view from the other, and then experiments. Until then, it’s a stimulating, unresolved conversation.

Which, to be honest, is part of the fun. You come for the metaphysics, you stay for the research programs it inspires.

On to food — and waste — and a lab with a very unusual cookie jar. Scientists at Southern Illinois University in Carbondale made protein-rich cookies, nicknamed “mu Bites,” by converting PET plastic and agricultural waste into food components using genetically engineered yeasts. The idea, as reported by Mashable, is to chip away at two big problems at once: plastic waste and future food shortages.

Important context here. This is an early-stage lab effort. The report credits genetically engineered yeasts and a conversion process from PET and ag waste into edible components. But from a safety, regulatory, and nutrition standpoint, there’s a long road from a lab cookie to anything people would actually eat. There’s no clinical testing or large-scale production in what we have here, and the details come via media coverage rather than a technical paper in the material we’re citing.

Still, the conceptual move — turning yesterday’s trash into tomorrow’s protein — is the kind of reframing that can reshape how we think about both food security and circular economies.

Agreed. If you can reliably transform hard-to-recycle streams into safe, nutritious inputs, that’s a win. The scientific burden is proving it’s consistent, safe, and scalable. For now, promising concept, preliminary step.

And I do appreciate the branding ambition. “Mu Bites” sounds like something a physicist would pack for a hike.

As long as the calories don’t escape via quantum tunneling.

Switching gears to the ground beneath our feet. A team led by Kim Blisniuk at San Jose State University looked at the San Andreas Fault and concluded that its slip rate has stayed steady over the past 10,000 years. Their data, collected at Sanborn County Park in California, suggests the fault is moving faster than earlier estimates.

A few key points. “Slip rate” is the average motion along the fault — how quickly two sides of the fault grind past each other over long timescales. Saying it’s been steady over 10,000 years means the long-term average hasn’t changed much in that window, at least at the site they studied.

Faster than thought is a phrase that gets attention. But what does it mean for risk?

Carefully: the result is about long-term rate, not about predicting when a particular earthquake will occur. Also, it’s based on data from a specific location, Sanborn County Park. While that’s valuable, we need broader sampling along the fault and independent confirmation before rewriting hazard models. Bigger slip rate numbers can affect how we estimate strain accumulation, but those updates come after peer review and integration with other datasets.

So, as always: one study is a piece of the puzzle, not the entire picture. Still, it nudges us to revisit a crucial system that so many people live along.

If you’re in the Americas, look up on August 27. The Weather Channel says a partial lunar eclipse is on the calendar, visible across North and South America. Some places may have crystal views under a heat dome; others could see clouds, showers, or thunderstorms gate-crashing the party.

Earlier reports noted the eclipse would cover about ninety-six percent. So it’s a deep partial, not a total, but still quite a show.

There’s something grounding about a lunar eclipse: the Earth quietly casting its shadow, reminding us that orbital mechanics keep rolling even when our calendars feel chaotic.

And it’s a good nudge to plan — check your local forecast if you’re hoping to watch, since the viewing depends on the weather.

From Earth’s shadow to a new scar on the Moon. NASA released fresh images on August 21 showing a sixty-foot-wide crater created when a SpaceX Falcon 9 upper stage hit the lunar surface on August 5, 2026. The images came from the Lunar Reconnaissance Orbiter, and NASA said the find highlights growing concerns about space debris.

Distinguishing features: this is not a natural impactor like a meteorite; it’s human hardware, the upper stage of a rocket. The crater size signals a significant kinetic punch, and being able to image it shows how carefully we can map the Moon’s surface.

The bigger conversation is about debris management — not just around Earth but in cis-lunar space. The images are a data point that our exploration leaves marks, and that those marks are trackable.

Exactly. And the “growing concerns” line is not hype; as missions multiply, so do spent stages and fragments. The science part is: we can document outcomes and use that knowledge to refine how we design trajectories and end-of-life plans.

In other words, we can be ambitious and tidy at the same time. Or at least try.

Staying with NASA, there was a more sobering note. The agency canceled the planned rescue of the Swift observatory after spacecraft control problems emerged. NASA had been working with partner Katalyst Space Technologies on a mission to capture the satellite and boost it to a higher orbit, but the inability to maintain control led to the decision.

This is a reminder that on-orbit capture and servicing are technically hard. You need precise control to rendezvous, grapple, and maneuver a spacecraft, especially an older one not designed for docking. If control can’t be maintained reliably, the risk to both the target and the servicing vehicle escalates quickly.

It’s disappointing, because the idea of giving a scientific satellite a second life is so appealing. But calling it when the control issues stack up is the responsible move.

Agreed. The “no heroics” principle in aerospace exists for good reasons. And the engineering lessons from the attempt — even a canceled one — often feed into the next, more capable mission.

Still, I’ll admit, I was rooting for a space tugboat moment.

We’ll get there. With checklists.

Now, a methods story that could ripple across genetics labs. A research team introduced something called Molecular Self-Assembly Induced Cloning. The idea: merge in‑vitro oligonucleotide self-assembly with cellular DNA repair to build DNA at scale in a single pot. Think one-tube recipes for thousands of gene fragments and big variant libraries.

And it uses microchip-synthesized oligonucleotides, which are short DNA pieces made in parallel at high throughput. The claim is that by letting designed fragments self-assemble and then leveraging the cell’s native repair machinery, you can turn many small pieces into many complete constructs in one go.

If you do biology, that’s a time and cost dream — less manual stitching, more building and testing.

With the standard caveats. We see a method description and a promise of scale — “thousands” — but we don’t have benchmark numbers, error rates, or comparisons to existing assembly pipelines in the material here. For labs, the details matter: fidelity, bias in which fragments assemble more easily, how robust it is across different sequence complexities, and whether it generalizes.

But as a direction, it’s exciting. Faster iteration in the design-build-test cycle can open new doors, from enzyme engineering to basic gene function maps.

Right. And when tools get better, science often follows. We just want the performance curves on the table.

I’m struck by a theme running through all these stories: the tension between bold ideas and the discipline to make them real. Consciousness as fundamental is a daring hypothesis; but you need testable consequences. Protein cookies from PET plastic challenge our sense of what counts as “food,” but must pass the gauntlet of safety and scale. A method promising thousands of DNA assemblies invites speed — and invites careful validation.

On the planetary side, the San Andreas result reminds us that the Earth runs on long clocks. A steady slip rate over ten millennia is the sort of claim that requires meticulous fieldwork and cautious interpretation. And in space, we have a new lunar crater that forces us to keep thinking about how to manage the by-products of exploration, and a canceled rescue that underlines how control is king.

And meanwhile, the Moon is about to step into our shadow again, as if to drop a quiet curtain between acts. It’s a nice moment to look up, breathe, and remember why we do any of this: because understanding brings a kind of steadiness.

Also because good measurements are beautiful. Says the person who alphabetizes his lab notebooks.

Daniel, I would never out you on-air for that. Oh wait, I just did.

I’ll take it as a commendation for orderly curiosity.
