“We took a powder of this material, put it in a tube, and we passed Berkeley air — just outdoor air — into the material to see how it would perform, and it was beautiful. It cleaned the air entirely of CO2. Everything,” said Omar Yaghi, the James and Neeltje Tretter Professor of Chemistry at UC Berkeley and senior author of a paper that will appear online Oct. 23 in the journal Nature.
This sounds promising.

Drinking water from brackish ground water, with only renewable energy input and no battery storage. Pretty cool.
“Being able to make drinking water with renewables, without requiring battery storage, is a massive grand challenge. And we’ve done it.”

NASA made some significant advancements in the search for extraterrestrial life this week. First, SpaceX launched NASA's Europa Clipper, which will eventually make about 50 flybys of Europa, the moon of Jupiter that scientists believe has ice-covered oceans that are twice the volume of Earth's. Second, NASA scientists published a paper in Nature describing computer modeling that predicts the presence of “radiatively habitable zones within exposed mid-latitude ice on Mars.” If there's water in those ‘radiatively habitable zones’, “mid-latitude ice exposures could represent the most easily accessible locations to search for extant life on Mars.”
I'm 54. I'm beginning to think it's entirely possible, that in my lifetime, we'll have evidence of extraterrestrial microbial life.
What a time to be alive.

Our findings reveal a significant reduction in PD occurrence following anti-tetanus vaccination, with a time-dependent association between the elapsed time since vaccination and both the rate and progression of PD. These results are supported by evidence that antimicrobial treatments significantly alter disease severity, suggesting the actual involvement of Clostridium Tetani in PD pathology.
This is only a preprint, but it's really interesting and definitely something to keep an eye on.
After reading it, I wondered if men get tetanus more than women, considering our penchant for playing and working in the dirt and handling rusty metal. Turns out we do (although relative prevalances may flip at age 60). Then I wondered if Parkinson's is more prevalent in men than in women. It is.
Interesting indeed.

In 2021, Koh came across a paper that discussed how to grapple with chaotic orbits from the perspective of symplectic geometry, an abstract field of math that is generally far removed from messy real-world details. She started to suspect that symplectic geometry might have the tools she needed to better understand orbits, and she got in touch with Agustin Moreno, the author of the paper. Moreno, then a postdoctoral fellow at Uppsala University in Sweden, was surprised and pleased to hear that someone at NASA was interested in his work. “It was unexpected, but it was also quite interesting and sort of motivating at the same time,” he said.
This is the beauty of pure academic research – someone makes an unforeseen connection and our collective knowledge grows. You never know how people will apply your work later. Pretty neat and compelling example of the value of basic research.

[L]arge language models such as ChatGPT can serve as valuable sources of information for informal caregivers, although they may not fully meet the needs of formal caregivers who seek specialized (clinical) answers. Nevertheless, even in its current state, ChatGPT was able to provide responses to some of the clinical questions related to dementia that were asked.
I suspect this is true for medical information on the web, too — good for most of us, incomplete for medical folks.

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage.
This is going to be interesting to watch over the next few years and decades. Battery technology is having a moment, for obvious reasons, and the Midwest stands to benefit if interest in sodium-ion technology continues to grow. There's a giant salt mine in Cleveland that extends beneath Lake Erie and another under Detroit.

Look at that! Rakus, the orangutan I posted about yesterday made today's New York Times!
Here's the original paper in Nature's Scientific Reports:

Three days after his wound appeared, Rakus did something that the researchers had never seen before. He ingested, chewed, and spit out bits of a nearby plant, then dabbed his wound with the resulting plant mix.
This is pretty remarkable. I'd really like to know if Rakus discovered the healing properties of the plant on his own, or if he learned it from another orangutan. If the latter, did the other teach him, or did he just observe the other healing his wounds?

Statistically speaking, bioluminescence first appeared on earth at least as early as 540 million years ago.

This is fascinating, perhaps morbidly so. Are we smart enough to avoid repeating history? We may be on the verge of finding out, measured on a scale of thousands (or maybe tens or hundreds of thousands) of years.

Yes. Yes I am.
Getting my second COVID booster shot this morning. I've got the first appointment of the day, but I could have any time I wanted—every single time slot was available when I scheduled it online last night.
At 52, I've been eligible for my second booster for some time now. I waited, though, waiting for signs of another surge and hoping to maximize the window during which it gives me elevated antibody levels. A bit of a game, I know, but not entirely without merit. As an immunologist, I bank more on long term memory and the T-cell response, but feel I might as well try to leverage the "sugar high" of an antibody surge.
The pharmacist let me leave right after the shot; she made no mention of a waiting period. So, I'm now sitting in my car in the parking lot for a self-imposed fifteen minute watch period.

"A sample of approximately 4 million W boson candidates is used to obtain [a mass W bosun], the precision of which exceeds that of all previous measurements combined....This measurement is in significant tension with the standard model expectation."
I love science, both the knowledge and the process of science. This paper, published with nearly 400 authors and in Science, likely the world's most respected peer-reviewed scientific journal, presents surprising results on the mass of W bosuns that lie way outside the value predicted by the standard model of physics. As such, it puts that model—which has guided physics research and understanding for decades—on the ropes.
But, the process of science won't let anyone jump to conclusions, not even four hundred authors writing in this journal. Nope, in a way, this paper really just kicks the process into the next gear. Testing and the oh-so-important work to verify the results come next. And, with this sort of work, that will take years.
So, is Frazier down?
Maybe, but in science and boxing, that doesn't mean the fight is over. This paper probably represents an early knockdown of the standard model (it's not the first). It took six for Foreman to be declared the winner over Frazier. So, now we wait. In the meantime, enjoy knowing that a revolution in our understanding of physics may be underway.
That doesn't mean the parlor games can't start now, though. And surely they have. Has Frazier fallen? We'll know someday, because...science.

"Polyakov’s analysis suggested that the four quarks banded together for a glorious 12 sextillionths of a second before an energy fluctuation conjured up two extra quarks and the group disintegrated into three mesons."
The contrast between the precision of "12 sextillitionths of a second" and the vagueness of "an energy fluctuation" that "conjures up two extra quarks" is somewhat hilarious. This is fascinating otherwise.

"But Nature’s survey suggests that even though researchers try to shrug off abuse, it might already have had a chilling effect on scientific communication. Those scientists who reported higher frequencies of trolling or personal attacks were also most likely to say that their experiences had greatly affected their willingness to speak to the media in the future...."
The pandemic, and our collective handling of it, has already had societal impacts that we fail to appreciate. A chilling effect on science, and its role in the distribution of knowledge, is disturbing. And that might not be the worst of it. Have we discouraged a generation of people from going into science as a career? Medicine? I don't know, maybe it's had the opposite effect in that regard. I have heard that applications to medical school are up. I didn't expect that.

A combination of natural infection with SARS-CoV-2 and an mRNA vaccine might provide some level of super protection.
