"It was lucky [that we survived], but we know from evolutionary biology that the emergence of a new species can happen in small, isolated populations...."

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.

Here's the original research published in Science.

Moths are more efficient pollinators than bees, shows new research (phys.org)

Amid widespread concern about the decline of wild pollinating insects like bees and butterflies, University of Sussex researchers have discovered that moths are particularly vital pollinators for nature.

Save the bees. And the moths.

Cancer and heart disease vaccines ‘ready by end of the decade’ (theguardian.com)

"Dr Paul Burton, the chief medical officer of pharmaceutical company Moderna, said he believes the firm will be able to offer such treatments for “all sorts of disease areas” in as little as five years."

This lightning speed timeframe still leaves plenty of time for anti-vaxxers and conspiracy theorists to ramp up their efforts.

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.

High-precision measurement of the W boson mass with the CDF II detector - PubMed (nih.gov)

"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."

Down goes Frazier?

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.

We met Jonathan for lunch in Harvard Square, dropped our bags in his dorm room, and headed to the Harvard Museum of Natural History. This is the third museum we've visited since he started here. It was fantastic, just like the others.

On Oreology, the fracture and flow of “milk's favorite cookie®” (scitation.org)

I love everything about this, including the fact that the research was supported by the federal government. I'm sure, sooner or later, some anti-science, clueless politician will cite it as an example of wasteful spending on basic research.

Ambitious scientists reach one of the deep seas' most inaccessible places (mashable.com)

The earth still has a lot to reveal. And exploration like this, into the previously unexplored depths of the ocean, will likely support applied research and innovation for decades to come.

"'Systematic searches for new drugs have shown that marine invertebrates produce more antibiotic, anti-cancer, and anti-inflammatory substances than any group of terrestrial organisms,' says the U.S. National Oceanic and Atmospheric Administration."

Evidence for European presence in the Americas in ad 1021 - Nature (nature.com)

"Here we provide evidence that the Vikings were present in Newfoundland in AD 1021."

Science sorting out history. Now the question becomes, how long will it take history to apply the science and teach this to children?

‘Impossible’ Particle Discovery Adds Key Piece to the Strong Force Puzzle | Quanta Magazine (quantamagazine.org)

"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.

‘I hope you die’: how the COVID pandemic unleashed attacks on scientists (nature.com)

"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.

China pledges to stop building new coal energy plants abroad (bbc.com)

It sort of feels like countries have finally realized they've been procrastinating on changing policies to address climate change, and are now scrambling to do so. Good and not good at the same time.

Covid is officially America's deadliest pandemic as U.S. fatalities surpass 1918 flu estimates (cnbc.com)

This could be viewed as reflective of the relative virulence of the SARS-CoV-2 virus compared to the virus responsible for the 1918 flu pandemic. It could also be viewed as reflective of the ability of misinformation to overcome 100+ years of scientific and medical progress in combating deadly viruses.

High genetic barrier to SARS-CoV-2 polyclonal neutralizing antibody escape - Nature (nature.com)

A combination of natural infection with SARS-CoV-2 and an mRNA vaccine might provide some level of super protection. I think there's a subset of the unvaccinated who are relying on their prior natural infection as justification for skipping the vaccine. Turns out, getting the vaccine might make them the fittest of all.

Engineers Have Proposed The First Model For a Physically Possible Warp Drive (sciencealert.com)

Turns out we don't need to break the speed of light barrier to become an interstellar species. We just need enormously powerful gravitational fields, like those provided by planets, to bend space time inside a warp drive.

Thinking about riding a warp drive around a planet makes me think of the song #Spacegrass# by Clutch:

Lay low, watch the universe expand.
Skyway, permanent Saturday.
Oh, by the way, Saturn is my rotary.

United States Patent: 8278036 (uspto.gov)

Oh, and applications of the mRNA technology in the Kariko paper were patented in 2012. The patents describe the process for practicing the technology in painstaking detail, as the law requires. And they expire in five years - in 2026, opening up incredible opportunities for new applications of the technology.

Suppression of RNA Recognition by Toll-like Receptors: The Impact of Nucleoside Modification and the Evolutionary Origin of RNA (sciencedirect.com)

This is the paper that lead directly to the mRNA technology underlying both the Pfizer and the Moderna vaccines. Talk of a Nobel Prize has started.

"This work was supported by National Institutes of Health grants...."

This paper is, quite possibly, the best argument of all time for supporting federal spending on basic scientific research. The entire world is aware of the benefit the research produced.

Whatever we're spending on basic research isn't enough. Figure out how to pay for it...and triple it.
