“I don’t think academic writing ever was wonderful”*…
Academic writing is famously abstruse. But, Stefan Washietl, founder of Paperpile, reminds us, it isn’t always so. As Rob Beschizza observes…
Stefan Washietl collected the shortest scientific papers. Some are unvarnished mathematical proofs, some are humor to amusing or incisive ends, others are clever-dickery that shoves the conclusion into the abstract. All are wonderful!…
Accessible academia: treat yourself to “The Shortest Papers Ever Published,” from @washietl and @paperpile via @Beschizza in @BoingBoing.

As we go for the gist, we might send voluminous birthday greetings to Constantine Samuel Rafinesque; he was born on this date in 1783. An autodidact naturalist, traveler, and writer who, in spite of work of variable reliability, substantially expanded knowledge via his extensive travels, collecting, cataloging, and naming huge numbers of plants and some animals. Among these are many new species he is credited with being the first to describe.
Years ahead of Charles Darwin’s theory of evolution, Rafinesque conceived his own ideas. He thought that species had, even within the timeframe of a century, a continuing tendency for varieties to appear that would diverge in their characteristics to the point of forming new species. Accordingly, he was over-enthusiastic at distinguishing what he called new species.
Rafinesque wrote prolifically, and often self-published. His work varied from brilliant insightfulness to carelessness, and raised the eyebrows– and sometimes the ire– of his scientific contemporaries. Indeed, he so incensed John James Audubon with his belief that Audubon has included unnamed species in his sketches of birds, that Audubon pranked him, feeding him sketches of imaginary fish… which Rafinesque believed and included in his writings, where (for 50 years or so) they remained as part of the scientific record.
“Trees are sanctuaries”*…
John Lewis-Stempel recounts a day in the life of an oak and the creatures that call it home…
Our friends the trees have an unremarkable life, or so it seems to us. They come into leaf, their fruit drops, or is gorged on by birds and the winds of autumn strip them of their dressing to leave them as the cold, bare sentinels of winter.
However, if we were to stand, tree-like ourselves, in a British copse and watch a single oak tree for an entire 24 hours — say when spring hatches out of winter — what would we see?…
Among their deceptively inert branches, trees shelter feathered Pavarottis, scuttling beetles, opportunistic fungi and fierce owls. A quick– and delightful– course in woodland ecology: “A day in the life of an oak tree, from mistle thrush in the morning to mice at midnight,” from @JLewisStempel in @Countrylifemag.

As we deliberate on the deciduous, we might send fertile birthday greetings to John Bartram; he was born on this date in 1699. An American botanist, horticulturist, and explorer, based in Philadelphia for most of his career, he was judged by Swedish botanist and taxonomist Carl Linnaeus to be the “greatest natural botanist in the world.”
He started what is known as Bartram’s Garden in 1728 at his farm in Kingsessing (now part of Philadelphia)– considered the first botanic garden in the United States. His sons and descendants operated it until 1850; it still operates under a partnership between the city of Philadelphia and a non-profit foundation, and was designated a National Historic Landmark in 1960.
“Uniformity is not nature’s way; diversity is nature’s way”*…
The U.S. boasts an impressively vast array of agricultural and botanical species. In an attempt to document that fact, The United States Department of Agriculture collected over 7,500 botanical watercolour paintings of evolving fruit and nut varieties in its Pomological Watercolor Collection, assembled between 1886 and 1942…
Independent publishing house Atelier Éditions is now revisiting this documentation of American pomology with the release of its latest book: An Illustrated Catalog of American Fruits & Nuts. “I came across the collection a few years back while researching botanical artworks,” says Pascale Georgiev, editorial director of Atelier. “There was such potential for a book with this collection, and it fits with our way of building archival or collection-based volumes.” The book is a biophilic wonder, with beautiful images of fruits popping with gentle colours and careful watercolour work. Accompanying them are often texts by well-versed experts, giving a fascinating insight into the agriculture behind the produce.
“We only produce and consume a handful of varieties today, mainly hybrids that cater to our desire for a certain sweetness, juiciness, smoothness, even specific shapes and lack of seeds,” says Pascale on the importance of the book’s current publication. “In some respects, the collection is a time capsule, and a reminder about the importance of diversity and conservation,” she adds…

As we fancy favorite fruits, we might carefully compose a birthday greeting to Pierre Athanase Larousse, the French grammarian and lexicographer, born in Toucy on this date in 1817. In 1856 Larousse and his partner Augustin Boyer published the New Dictionary of the French Language, the forerunner of the Petit Larousse. On December 27, 1863 the first volume of Larousse’s masterwork, the great encyclopedic dictionary, the Grand dictionnaire universel du XIXe siècle (Great Universal 19th-Century Dictionary), appeared.
Then, in 1938, the Larousse publishing house published an encyclopedia of gastronomy, Larousse Gastronomique edited by Prosper Montagne.
And Happy Mole Day (or to be more precise, October 23 at 6:02 pm, in honor of Avogadro’s number: 6.02 x 1023 items are in a mole — it’s the chemist’s version of a dozen)
“Plants can’t move, yet the insects come to them and spread their pollen”*…
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).
“The keeping of bees is like the direction of sunbeams”*…
And moving those bees…
About 75% of crops and one-third of the global food supply rely on pollinators such as honeybees, according to Our World in Data. But farmers have to rely on commercially managed honeybees trucked in from other states to help pollinate certain crops, such as almonds, because there aren’t enough wild bees to do the job. And trucking bees hundreds or thousands of miles is not simple…
Honeybees are disappearing due to shrinking habitats and the growing use of pesticides. When there aren’t enough bees to pollinate fields of crops, companies pay beekeepers to transport their colonies of bees for pollination season.
“The great pollination migration” happens every year in February when the almonds bloom in California.
Pollinating the seemingly endless fields of almond trees in California requires 85% to 90% of all honeybees available to pollinate in the U.S… Bees are trucked into California from across the country…
Earl and Merle Warren are brothers, truck drivers and co-owners of Star’s Ferry Transport, based in Burley, Idaho. They started hauling bees for a local beekeeper in 1990 and moved about 50 loads of approximately 22 million bees each last year for companies such as Browning’s Honey Co.
“This is not like a load of steel or lumber. These are live creatures. This is those beekeepers’ livelihoods, so we do everything possible to keep them alive,” Earl Warren said.
Some beekeepers estimate that every time you move a truck of bees, up to 5% of the queens die… Minimizing stress for bees is critical, so beekeepers rely on experienced truck drivers to navigate difficult situations such as warm weather, few opportunities to stop during the day and inspections…

As we ponder pollination, we might spare a thought for a scientist whose very field of study was (and is) made possible by bees, Anders (Andreas) Dahl; he died on this date in 1789. A botanist and student of Carl Linnaeus, he is the inspiration for, the namesake of, the dahlia flower.
