In Memoriam Rose Paterson

I was greatly saddened this morning to learn that Rose Paterson had passed away.  I had the pleasure of meeting her three years ago while we and our families were both visiting her brother in Northumberland.  She was a lovely and talented person, who, among her accomplishments, once crossed Mongolia on horseback.  As she lived near Ellesmere, Shropshire, here is her obituary in the Shropshire Star.  My sympathy to her family.

Digital Evolution

Cloutier et al. (Nature, March 18, 2020) recently described a fossil fish (pardon the paraphyly), named Elpistostege watsoni, whose skeletal remains suggest the emergence of digits:
Here we report a 1.57-metre-long articulated specimen of Elpistostege watsoni from the Upper Devonian period of Canada, which represents—to our knowledge—the most complete elpistostegalian yet found. High-energy computed tomography reveals that the skeleton of the pectoral fin has four proximodistal rows of radials (two of which include branched carpals) as well as two distal rows that are organized as digits and putative digits.
Never has there been a better reason to work fingers to the bone.

Et Tu, Okmok?

A June 22, 2020, article in the journal Proceedings of the National Academy of Sciences, entitled Extreme climate after massive eruption of Alaska’s Okmok volcano in 43 BCE and effects on the late Roman Republic and Ptolemaic Kingdom, suggests that the eruption of political unrest following the assassination of Julius Caesar in 44 B.C. may have been followed by climate unrest unleashed by a massive Alaskan volcano:
The assassination of Julius Caesar in 44 BCE triggered a power struggle that ultimately ended the Roman Republic and, eventually, the Ptolemaic Kingdom, leading to the rise of the Roman Empire. Climate proxies and written documents indicate that this struggle occurred during a period of unusually inclement weather, famine, and disease in the Mediterranean region; historians have previously speculated that a large volcanic eruption of unknown origin was the most likely cause. Here we show using well-dated volcanic fallout records in six Arctic ice cores that one of the largest volcanic eruptions of the past 2,500 [years] occurred in early 43 BCE, with distinct geochemistry of tephra deposited during the event identifying the Okmok volcano in Alaska as the source.
This study, by McConnell et al., suggests that the Roman Republic may have been left quite literally on the ash heap of history.

Thinking Outside The Box

I discovered this beautiful little chelonian today, which made my day.

Shell Shock

Nature magazine reports that palaeontologists may have cracked the egg-laying behavior of several prehistoric amniotes.  Rather than hard, at least some terrestrial dinosaur eggs may have been soft-shelled, while it now appears possible that some prehistoric marine "reptiles" (pardon the paraphyly) laid their eggs on land.  Such paradigm shifts foul the nests of prior hypotheses.

Two Wings Fly Together

The United States Supreme Court ("Supremes") released a remarkable decision on June 15, 2020, concerning equality before the law.  In the case of Bostock v. Clayton County, Georgia, a robust majority of six justices, including all four justices generally regarded as leaning leftward alongside two justices usually regarded as learning rightward (that is, Chief Justice John Glover Roberts and Associate Justice Neil McGill Gorsuch), agreed on a decision written by Justice Gorsuch.  Here is the essence of their decision:
Sometimes small gestures can have unexpected consequences.  Major initiatives practically guarantee them.  In our time, few pieces of federal legislation rank in significance with the Civil Rights Act of 1964.  There, in Title VII, Congress outlawed discrimination in the workplace on the basis of race, color, religion, sex, or national origin.  Today, we must decide whether an employer can fire someone simply for being homosexual or transgender. The answer is clear.  An employer who fires an individual for being homosexual or transgender fires that person for traits or actions it would not have questioned in members of a different sex.  Sex plays a necessary and undisguisable role in the decision, exactly what Title VII forbids.
Those who adopted the Civil Rights Act might not have anticipated their work would lead to this particular result.  Likely, they weren’t thinking about many of the Act’s consequences that have become apparent over the years, including its prohibition against discrimination on the basis of motherhood or its ban on the sexual harassment of male employees.  But the limits of the drafters’ imagination supply no reason to ignore the law’s demands.  When the express terms of a statute give us one answer and extratextual considerations suggest another, it’s no contest.  Only the written word is the law, and all persons are entitled to its benefit.
Given its bipartisan nature and decisive mathematics, this decision has now settled a fundamental issue of equal rights for the foreseeable future.  Justices Alito, Thomas, and Kavanaugh dissented from the majority decision.

Reflection Inflection Point

The environment blog YaleEnvironment360 recently published a thoughtful and timely essay, entitled When Social Distancing Ends, Will We Rethink the World We Want?, by Bill McKibben.  With reference to the current SARS-CoV-2 pandemic, McKibben notes that
We are on the closest thing ever to a worldwide meditation retreat, with billions finding time to think about their lives.
We having examined our lives and society, McKibben considers what we might decide to make of our future.

SARS-CoV-2 Pathogenicity

The Proceedings of the National Academy of Sciences ("PNAS") published an article entitled "Genomic determinants of pathogenicity in SARS-CoV-2 and other human coronaviruses", by Ayal B. Gussow et al., on June 10, 2020.  The article explores
crucial genomic features that are unique to SARS-CoV-2 and two other deadly coronaviruses, SARS-CoV and MERS-CoV [and that] correlate with the high fatality rate of these coronaviruses...
This short article is well worth reading.

Tyrannosaurus Lex

On May 20, 2020, in Murray v. BEJ Minerals, the Supreme Court of Montana ("Montana Supremes") granted custody of a Tyrannosaurus rex and bits of a Triceratops.  The legal issue, as framed by the United States Court of Appeals for the 9th Circuit, is
Whether, under Montana law, dinosaur fossils constitute “minerals” for the purpose of a mineral reservation?
The Montana Supremes held as follows:
We conclude that, under Montana law, dinosaur fossils do not constitute “minerals” for the purpose of a mineral reservation.  The ordinary and natural meaning of “mineral”—as it is used in the context of a general mineral reservation and mineral transactions—involves resources such as hard compounds, oil, or gas, mined as a raw material, to be used for further processing, refinement, and economic exploitation.  Although a material’s mineral content may render the material rare and valuable, and therefore within the ordinary and natural meaning of “mineral,” dinosaur fossils are not considered rare and valuable because of their mineral properties; rather, fossils are valuable because of characteristics other than mineral composition.  Finally, dinosaur fossils’ relation to the surface, and the effect their removal has on the value of the surface estate, is the final factor in determining dinosaur fossils to be outside the ordinary and natural meaning of “mineral,” as that term was used in the [current and prior land owners'] mineral deed.  We decline to stretch the term “mineral” so far outside its ordinary meaning as to include dinosaur fossils.
In her vigorous dissent, Justice Ingrid Gustafson pointed out that "The dinosaur fossils here...have a 100% mineral composition."  However, in Montana at least, this legal theory about such wondrous fossils has now gone the way of the dinosaurs.

Technology King Arthur

The last book I was able to sign out from Dewey Library before MIT shut down in March 2020 was THE NATURE of TECHNOLOGY - What It Is and How it Evolves, by W. Brian Arthur.  I love it.  I do not agree with everything in his theory of the structure and evolution of technology, but I do find his schemata useful and share his admiration of Charles Darwin's contributions to evolutionary theory.  Here is a lecture he gave on the origins and evolution of technology.

Awesome Aussie Murids

I have a soft spot in my heart for Australasian murids.  I like them so much I did my Ph.D. on their genetics and evolution.  So, when I came across this article in Australian Geographic, entitled "Here are 7 clever Aussie native rodents", I had to share it.

Masters Of Artificial Intelligence

Harvard Business School professors Karim Lakhani and Marco Iansiti recently published a marvelous new book entitled Competing in the Age of AI - Strategy and Leadership When Algorithms and Networks Run the World.  This is the best account I have ever read of the seismic effects artificial intelligence will surely have, and, in some cases, has already had, on business, the economy, management, and public policy.  I thoroughly recommend it.
