“Speed and acceleration are merely the dream of making time reversible”*…

In the early 20th century, there was Futurism…

The Italian Futurists, from the first half of the twentieth century… wanted to drive modernisation in turn-of-the-century Italy at a much faster pace. They saw the potential in machines, and technology, to transform the country, to demand progress. It was not however merely an incrementalist approach they were after: words like annihilation, destruction and apocalypse appear in the writings of the futurists, including the author of The Futurist Manifesto, Filippo Tomasso Marinetti. ‘We want to glorify war – the only cure for the world…’ Marinetti proclaimed – this was not for the faint hearted! That same Marinetti was the founder of the Partito Politico Futuristo in 1918, which became part of Mussolini’s Fascist party in 1919. Things did not go well after that.

Beautiful Ideas Which Kill: Accelerationism, Futurism and Bewilderment

And now, in the early 21st century, there is Accelerationism…

These [politically-motivated mass] killings were often linked to the alt-right, described as an outgrowth of the movement’s rise in the Trump era. But many of these suspected killers, from Atomwaffen thugs to the New Zealand mosque shooter to the Poway synagogue attacker, are more tightly connected to a newer and more radical white supremacist ideology, one that dismisses the alt-right as cowards unwilling to take matters into their own hands.

It’s called “accelerationism,” and it rests on the idea that Western governments are irreparably corrupt. As a result, the best thing white supremacists can do is accelerate their demise by sowing chaos and creating political tension. Accelerationist ideas have been cited in mass shooters’ manifestos — explicitly, in the case of the New Zealand killer — and are frequently referenced in white supremacist web forums and chat rooms.

Accelerationists reject any effort to seize political power through the ballot box, dismissing the alt-right’s attempts to engage in mass politics as pointless. If one votes, one should vote for the most extreme candidate, left or right, to intensify points of political and social conflict within Western societies. Their preferred tactic for heightening these contradictions, however, is not voting, but violence — attacking racial minorities and Jews as a way of bringing us closer to a race war, and using firearms to spark divisive fights over gun control. The ultimate goal is to collapse the government itself; they hope for a white-dominated future after that…

And for a reminder of the not-so-obvious ways that movements like these live on, see “The Intentionally Scandalous 1932 Cookbook That Stands the Test of Time,” on The Futurist Cookbook, by Futurist Manifesto author Filippo Tommaso Marinetti… which foreshadowed the “food as fuel” culinary movements that we see today.

As we slow down, we might send a “Alles Gute zum Geburtstag” to the polymathic Gottfried Wilhelm Leibniz, the philosopher, mathematician, and political adviser, who was important both as a metaphysician and as a logician, but who is probably best remembered for his independent invention of the calculus; he was born on this date in 1646.  Leibniz discovered and developed differential and integral calculus on his own, which he published in 1684; but he became involved in a bitter priority dispute with Isaac Newton, whose ideas on the calculus were developed earlier (1665), but published later (1687).

As it happens, Leibnitz was a wry and incisive political and cultural observer.  Consider, e.g…

If geometry conflicted with our passions and our present concerns as much as morality does, we would dispute it and transgress it almost as much–in spite of all Euclid’s and Archimedes’ demonstrations, which would be treated as fantasies and deemed to be full of fallacies. [Leibniz, New Essays, p. 95]



“Sharks. I never saw that coming.”*…

While many land-based predators (like wolves) avoid cities, scientists tracking sharks in Florida’s Biscayne Bay found the fish spent just as much time near Miami as away from it. Warren Cornwall explains…

Certain kinds of wildlife are notorious for thriving in urban settings. Think rats, rock pigeons and even the occasional coyote. Now, Florida scientists have added another creature to the list: sharks.

While many large predators show little appetite for city living, an intriguing project tracking the movements of sharks as fearsome as hammerheads revealed the fish are unexpectedly tolerant of life up close to the 6 million humans of greater Miami.

“We were surprised to find that the sharks we tracked spent so much time near the lights and sounds of the busy city, often close to shore, no matter the time of day,” said Neil Hammerschlag, director of the University of Miami’s Shark Research and Conservation Program.

Ecologists group animals into two main categories when it comes to their tolerance for human development. Some, like raccoons or rats, have figured out how to capitalize on the trash we make and the nooks and crannies we build. They are “urban exploiters.” Then there are the animals like mountain lions, lynxes and wolves that generally give human infrastructure a wide berth, often abandoning habitat where roads or buildings encroach. These are the “urban avoiders.”

As that list suggests, on land, big, toothy predators generally keep their distance from the din of the city. But less is known about their aquatic counterparts. So, a group of researchers set out to see if the sharks of Miami’s Biscayne Bay might shed some light on the matter…

As we hug the shore, we might send deep birthday greetings to Robert Ballard; he was born on this date in 1942. An oceanographer, explorer, retired naval officer, and professor, he noted for his work in underwater archaeology: maritime archaeology and archaeology of shipwrecks. He is probably best known for his discoveries of the wrecks of the RMS Titanic in 1985, the battleship Bismarck in 1989, the aircraft carrier USS Yorktown in 1998, and the wreck of John F. Kennedy’s PT-109 in 2002. But he believes that his most important discovery was the existence of hydrothermal vents.

“Plants can’t move, yet the insects come to them and spread their pollen”*…

A canola plant damaged by heat and drought in Saskatchewan, Canada last July

The impact of climate change on agriculture is much discussed– but mostly at the level of yields. Carolyn Beans looks into what a warming planet means for fertilization and reproduction…

… heat is a pollen killer. Even with adequate water, heat can damage pollen and prevent fertilization in canola and many other crops, including corn, peanuts, and rice.

For this reason, many growers aim for crops to bloom before the temperature rises. But as climate change increases the number of days over 90 degrees in regions across the globe, and multi-day stretches of extreme heat become more common, getting that timing right could become challenging, if not impossible.

Faced with a warmer future, researchers are searching for ways to help pollen beat the heat. They’re uncovering genes that could lead to more heat-tolerant varieties and breeding cultivars that can survive winter and flower before heat strikes. They’re probing pollen’s precise limits and even harvesting pollen at large scales to spray directly onto crops when weather improves.

At stake is much of our diet. Every seed, grain, and fruit that we eat is a direct product of pollination…

Farmers and scientists are increasingly observing that unusually high springtime temperatures can kill pollen and interfere with the fertilization of crops. Researchers are now searching for ways to help pollen beat the heat, including developing more heat-tolerant varieties: “Pollen and Heat: A Looming Challenge for Global Agriculture,” from @carolynmbeans in @YaleE360.

As we try to stay cool, we might recall that it was on this date in 1960 that chlorophyll– the green pigment responsible for photosynthesis in plants– was first synthesized. The feat was accomplished by Robert Burns Woodward, the preeminent synthetic organic chemist of the twentieth century, who was awarded the Nobel Prize in 1965 for this and other syntheses of complex natural compounds (including Vitamin b12).

“Homo sapiens, the only creature endowed with reason, is also the only creature to pin its existence on things unreasonable”*…

We appeared 800,000-300,000 years ago, or in the last 1.5%-5.3% of hominid history

How, Sarah Constantin asks, did we humans get so smart?

If you zoom way out and look at the history of life on Earth, humans evolved incredibly recently. The Hominidae — the family that includes orangutans, chimpanzees, bonobos, gorillas, and humans — only arose 20 million years ago, in the most recent 0.5% of evolutionary history.

Within the Hominidae, in turn, Homo sapiens is a very recent development [see image at top]. We appeared 800,000-300,000 years ago, or in the last 1.5%-5.3% of hominid history.

If you look at early hominid “technological” milestones like tool use or cooking, though, they’re a lot more spread out over time. That’s interesting.

There’s nothing to suggest that a single physical change in brains should have given us both tool use and fire, for instance; if that were the case, you’d expect to see them show up at the same time.

Purposeful problem-solving behaviors like tool use and cooking are not unique to hominids; some other mammals and birds use tools, and lots of vertebrates (including birds and fish) can learn to solve puzzles to get a food reward. The general class of “problem-solving behavior” that we see, to one degree or another, in many vertebrates, doesn’t seem to have arisen surprisingly fast compared to the existence of animals in general.

However, to the extent that Homo sapiens has unique cognitive abilities, those did show up surprisingly recently, and it makes sense to privilege the hypothesis that they have a common physical cause.

So what are these special human-unique cognitive abilities?…

As we study our species, we might send self-examining birthday greetings to Giambattista Vico; he was born on this date in 1668.  A political philosopher, rhetorician, historian, and jurist, Vico was one of the greatest Enlightenment thinkers.  Best known for the Scienza Nuova (1725, often published in English as New Science), he famously criticized the expansion and development of modern rationalism and was an apologist for classical antiquity.

He was an important precursor of systemic and complexity thinking (as opposed to Cartesian analysis and other kinds of reductionism); and he can be credited with the first exposition of the fundamental aspects of social science (and so, is considered by many to be the first forerunner of cultural anthropology and ethnography), though his views did not necessarily influence the first social scientists.  Vico is often claimed to have fathered modern philosophy of history (although the term is not found in his text; Vico speaks of a “history of philosophy narrated philosophically’).  While he was not strictly speaking a historicist, interest in him has been driven by historicists (like Isaiah Berlin).


“I have all these great genes, but they’re recessive. That’s the problem here.”*…

DNA Sequence chromatograms produced by automated sequencing machines

When the Human Genome Initiative published its first findings in 2002, the world was shocked. Genetic biologists, however, had long ago come to realize that DNA sequences are only part of the story of how organisms develop…

Fueled by the expectation that knowing the sequence of our DNA would tell us who we are, US funding agencies launched one of the most ambitious scientific efforts of all time in 1990. I refer, of course, to the Human Genome Initiative. Since then, the pace of that effort has been furious:even before the decade was over, the finishing line was clearly in view. When in February 2001, two rival teams announced the results of their first analysis of this invaluable information, their report made front-page headlines around the world. Humans, it seems, have far fewer genes than had been expected — in fact, only a third more than the lowly roundworm. How can this be? And what does it mean? Are we really so similar to, and so little more than, mere worms? News of the extent of our commonality with all living species is as stunning as it is humbling. But at the same time, it invites a certain incredulity — and that not merely because of human pride. Simple observation of the manifest diversity of life also makes us resist, for it is impossible not to wonder: what is it, if not the number (and in many cases, even the structure) of the ‘genes’ encoded in our DNA that accounts for the extraordinary differences among living organisms? For the answer to this question, it seems that we will have to look to the regulatory dynamics that determine how the sequence information of the DNA is to be used by the cell. Here, in the complex regulation of genetic transcription, of translation, of protein structure and function, is where we will find what makes us human beings rather than worms, flies or mice. Knowledge of the sequence of our DNA can tell us an enormous amount, but it can almost certainly not tell us who we are.

But not everyone was taken aback by this news. While readers of the popular press may have been stunned, few biologists working at the frontiers of research in molecular genetics were astonished. True, they had expected a larger number of human ‘genes’, but they had long ago come to realise that DNA sequences are only part of the story of how organisms develop, and even of what we mean by a ‘gene’. They recognise, for example, that the spatial and temporal patterns of expression of a gene are even more crucial to the specification of an organism than the structure of that ‘gene’ is. They also know that no single definition of this word ‘gene’ can suffice. Of the many different definitions that are required to make sense of current usage, two stand out with particular clarity: one referring to a particular region of the DNA, and another to the unit of messenger RNA that is used in the synthesis of a particular protein. The number of genes of the second kind is in fact very much larger than that of the first kind (current estimates suggest more than ten times as many), for the fact is that many different ‘genes’ can be constructed out of a single specified region of the DNA. Because the particular context in which they use the word makes its meaning quite clear, ambiguities in usage rarely create problems for practising biologists. Not so, however, for most readers. Outside the laboratory, such linguistic uncertainties can lead to both confusion and misunderstanding — not only around the question of how many genes we have, but also of what genes are made of, where they reside, what they do and, perhaps most important, what genes are for.

The good news is that research in genetics has never been more exciting, and over the last few decades both the depth and the breadth of our understanding of the nature of genetic activity have grown spectacularly. With each advance, the picture of the role of genes in development that biologists learn to draw grows ever more complex and sophisticated, and in ever more conspicuous defiance of the simple mantra with which they began. The word ‘gene’ does not begin to do justice to the ingenuity of the mechanisms required to put biological organisms together — no more than the concept of the neuron does to the ingenuity and dynamic complexity of neural organisation, and no more than talk of individual minds to the complexities of language and cognition…

Unpacking the genome hasn’t turned out to be the master key to understanding life that many thought it would be– but that’s no reason not to celebrate what it does illuminate: “The century of the gene,” from Evelyn Fox Keller in @EngelsbergIdeas.

As we investigate inheritance, we might spare a thought for D’Arcy Wentworth Thompson; he died on this date in 1948.  A classics scholar who was also an accomplished biologist and mathematician, Thompson is best remembered for On Growth and Form (1917, new ed. 1942), a profound consideration of the shapes of living things, starting from the simple premise that “everything is the way it is because it got that way.”  Thus one must study not only finished forms, but also the forces that molded them: “the form of an object is a ‘diagram of forces’, in this sense, at least, that from it we can judge of or deduce the forces that are acting or have acted upon it.”

The book paved the way for the scientific explanation of morphogenesis, the process by which patterns are formed in plants and animals.  Thompson’s description of the mathematical beauty of nature inspired thinkers as diverse as Alan Turing and Claude Levi-Strauss, and artists including Henry Moore, Salvador Dali, and Jackson Pollock.  Peter Medawar, the 1960 Nobel Laureate in Medicine, called On Growth and Form “the finest work of literature in all the annals of science that have been recorded in the English tongue.”
