Via the always excellent Web Curios, we are referred to quite a grand and ongoing project soliciting nominees and showcasing one molecule per month, without fail, since 1996, which is not only impressive for its longevity but also for its accessible scholarship for each chemical compound. Recently showcased molecules include the alchemists’ White Phosphorus, Androstenone, the porcine pheromone that can stop dogs barking, wine lactone that gives the drink its fragrant notes and astaxanthin, the ingredient responsive for making flamingoes pink. Check it out and let us know what you’ve learned or what molecule you’d like to know more about.

Whilst not definitive proof of past life in the form of preserved or residual biological matter, exploring the Martian Jezero crater the Perseverance rover has detected organic molecules, gaining insights about the Red Planet’s carbon cycles and the potential to host life as we know it—utilising its deep ultraviolet laser instrumentation with the title acronym for Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals. The non-uniformity of these deposits—which will be sampled and hopefully returned to Earth for further study in 2030, suggests that different catalysts were in action to synthesise or metabolise these chemicals over time, preserving them under distinct conditions, possibly consistent with biological processes.

operation sober popeye (10. 872)
Also known under the codenames Motorpool and Intermediary-Compatriot and repudiated as an unacceptable tactic in warfare after leaks in the Pentagon Papers and unwelcome press coverage with a US Senate resolution passed on this day in 1973, the military cloud-seeding program carried out from 1967 to 1972 attempted chemical modification of the weather with the aim of extending monsoon seasons and disrupting the North Vietnamese supply-chain along the Ho Chi Minh Trail by soften road surfaces and causing landslides. Operations in secret extended over Thailand, Laos and Cambodia. Despite its highly classified nature, the 54th Weather Reconnaissance Squadron, the unit chiefly responsible for the tests, publicly and prominently used the slogan “make mud, not war.” The American people deciding that such measures had no place on the battlefield, weather disruption falls presently under the auspices of the Environmental Modification Convention.

exposome (10. 658)
We learn via the New Shelton wet/dry that the field of exposomics was coined in 2005 to describe the <aetiology of chronic disease and cancers due to environmental factors and has since been expanded as a heuristic approach to gauging exposure to pollutants and how toxins are metabolised and change in the body once incorporated. Taken rather dismissively like the statistic that we swallow a fair share of spiders annually, the idea that we ingest a credit card per week of microplastics ought to be a cause for alarm and what’s inert and what’s potentially reactive and enduring is a big unknown for public health and well-being as we continue to trash our planet.

tomorrowland 2055 (10. 526)
Due to budget cuts which already limited the number of planned attractions, Disneyland reluctantly opened up its last themed land to commercial sponsorship, becoming something of a showcase of corporate America, including Dutch Boy Paint, the agrochemical giant Monsanto and its Hall of Chemistry and General Electric with its Carousel of Progress. Space Mountain was proposed initially as a functioning space port for Disney World in the vicinity of Cape Canaveral.

innerspace (10. 307)
Designed by astrophysicist Frank Drake (see previously) with input from Carl Sagan and others as a proof-of-concept demonstration rather than an attempt to enter into to dialogue with extra-terrestrials and criticised as being too low-resolution to be recognisable to future recipients, the Arecibo Message (see also here and here) was beamed from the radio observatory in Puerto Rico on this date in 1974, aimed in the direction of the globular star cluster M13, some twenty-five thousand light-years from Earth. When encoded graphically, the some sixteen hundred bits of data produce the pictured image with seven elements, from top to bottom: the decimal system, the valance of the elements that make up DNA, the chemical formula for the constituent nucleotides, the approximate number of said organic molecules in the human genome with representation of the double-helix structure, the average dimensions of a human male plus the Earth’s population (four billion, compared to eight billion presently), a representation of the Solar System and finally in purple, the Arecibo telescope. The precise number of bits, 1 679, is a semiprime—that is, the product of two prime numbers, seventy-three and twenty-three, to prompt one toward the right orientation, the alternate arrangement producing static. An answer came in 2001 in the form of a crop circle near the Chilbolton radio telescope in Hampshire—rather intricately replacing the carbon-based DNA with silicon and the pictogram of the human figure looks alien—though this reply was unfortunately an elaborate hoax.

biosphere 2
Under construction since 1987, the environmental research facility in Oracle in the US state of Arizona host to the largest closed vivarium—that is sealed ecosystem—ever built, more than a hectare in size and meant to demonstrate the viability of artificial and self-sustaining life-support systems in outer space, began its first forty-eight month mission on this day in 1991, with a crew of eight impounded under the dome. With the crew enduring oxygen deprivation and near starvation over the two year trial and not all biomes that were to represent the different regions of Spaceship Earth thriving plus pests, lessons were learned and changes implemented, although by the time the second mission was to commence, there was vicious fighting amongst the project managers and accusations of bad science and bad methodology, including the engagement of Steve Bannon who put the programme into receivership incorporated under the name Space Biosphere Ventures. All this took place outside of the framework of competitive reality television and the era of business sectarianism. Since 2007, Biosphere 2 has been owned and operated by the University of Arizona, conducting experiments in atmospheric research, soil geochemistry and climate change and holding special week-long space-camps for students.

eka-iridium
First synthesised on this day in 1982 at the Darmstadt Institute for Heavy Ion Research (GIS, Gesellschaft fรผr Schwerionforschung) the synthetic meitnerium (Mt) was given the above provisional designation following Grigory Mendeleev’s nomenclature for undiscovered atomic elements—the convention becoming a placeholder shortly before its discovery with the controversy over the honours and naming-system being overhauled.The research-team wanted to recognise the previously overlooked contributions of physicist Lise Meitner for her pioneering work in nuclear fission and her co-discovery of the element protactinium with Otto Hahn. Curium being named for both Pierre and Marie Curie, meitnerium is the only element named for a non-mythological woman. Because of its half-life of mere seconds even in the most stable isotope, few of its chemical properties are known though study continues, and its periodic neighbours, hassium and darmstadtium, are both named for the above laboratory.

kardashev scale
From Kottke’s Quick Links, we are treated to another lucid and illuminating vignette from Kurzgesagt on anthropic limitations when comes to looking for intelligent life elsewhere in the Cosmos and how energy signatures might be the one common thread of evidence, as it were, when it comes to recognising alien civilisation and looking beyond our limited and biased horizons.
Proposed in 1964 by astrophysicist Nikolai Kardashev (*1932 – †2019), the eponymous scale was a way to gauge the technological state of a culture—terrestrial or otherwise—based on the amount of energy that they are able to use efficiently and to what ends. Type I can effectively harness all the light and heat energy that falls on the planet from its home star(s)—which is about four magnitudes greater than what humans generally generate mostly from fossil fuels but possibly attainable if we continue with scientific advancement. Type II would be capable of harvesting the net energy of its solar system, possibly isolating itself and obscuring its existence with a Dyson Sphere. Type III could harness the energetic output of their entire galaxy. Alternatively, mathematician John David Barrow has inverted the scale and finds greater economy in miniaturisation and what he has classified as microdimensional mastery—going from human scale construction and manipulation down to chemistry, nanotechologies, genetic manipulation, atomic tinkering and eventual alternation to the fabric of space-time.

erbario farmaceutico
Building on a history of reference, anecdote and experimentation already established for millennia at the time of publication of this fifteenth century volume from the Veneto, we appreciated the prompt to learning more behind this category of guidebook known as the herbal (Herbarius, Erbario).
Pairing images that aid in identification with others that represented supposed pharmacological merit—as well as toxic, tonic, culinary and magical properties, extensive accompanying texts and captions inform modern ideas (but certainly do not supplant them—a feature of such collections is that they advance and improve tempered by science and scholarship but are always good to peruse for perspective and perhaps insight) of taxonomy, chemistry and medicine.

course of medication
Via Slashdot, we learn that a novel organic chemical compound has been isolated by an artificial intelligence trained on the corpus of literature of pathology and drug-resistance that potentially has powerful implications for continuing to combat infectious disease and make amends for the systematic abuse of antibiotics (over-prescribing, battery livestock, wastewater, etc.) that threatens to revert medical science to that of the Middle Ages.
The compound, named halcine after HAL 9000 by one member of the Massachusetts Institute of Technology researchers, seems to put back in our quiver the means to deal with the most pernicious strains of multi-resistant compounds that make environments that ought to be sterile incubators for germs that have become immune to traditional medicine through over-use and over-exposure. Furthermore, given the expense that new drugs trials entail—making their development a pricy trade-off despite the benefit of lives saved, being able to find leads to follow from computer models may usher the best contenders to the laboratory first.

käsecore
When I first caught the headline of this study, I assumed it meant that Hip Hop did something to stimulate the taste buds rather than having aged wheels of Emmentaler (hobby cheesemaker’s Beat Wampfler’s signature Muttenglück) in immersive soundscapes for six months. I was a bit sceptical about the claims that each sample, exposed to different musical genres, displayed a different taste profile but indeed sonic chemistry is a discipline that researchers are just beginning to appreciate and explore. Reportedly, the cheese aged accompanied by Hip Hop turned out zestier and the quintessentially Swiss cheese had bigger holes—eyes, in the trade.

Via Digg, the United Nations has declared 2019 to be the Year of the Periodic Table in recognition of the moment of insight that Dmitri Mendeleev had one hundred-fifty years ago in 1869 when he committed each of the sixty-nine then known distinct chemical elements on note cards and arranged them by properties in such a fashion as to predict, forecast the existence of yet unknown substances that would later fall neatly in place.
Not to discount the genius of the moment, the development of the familiar design was a lengthy process with many alternate proposals, visual cul-de-sacs (see also here, here and here) and effort that draws off the research and inspiration of many that came before and tried to communicate some essential quality about the building blocks of Nature. In addition to the symbolic chemistry that John Dalton proffered in 1803 to help limn his modern Atomic Theory, the Conversation takes a look at the other stages and versions—with some more radical deviations—that culminate with the iconic and instantly recognisable classroom model.

olfactory bulb
Via Marginal Revolution, we are introduced to artist Sissel Tolaas celebrates the olfactory when the world becomes estrangingly deodorised, enshrining everything that’s visceral and memorable about the often derided sense of smell.
Her brave and unabashed landscapes perfumed with perhaps what we’d as soon forget create a odour distinctive to time and place and craft a unique narrative with each waft—telegraphing specific characteristics that rather defy digitalisation and the usual heraldic shorthand, though our sensibilities seem to shy away from confronting the vulgar without detergent. Tolaas has even crafted a compliment of vials containing bespoke smells never smelt before to break in case of an event that one wants to create an indelible memory for. It’s assuredly a good thing that we must needs be present for the perception that is most immediate and unmitigated to the brain (though whole industries are devoted to building those barriers) and to perform witchcraft, chemistry and biology, unable to elevate ourselves above the miasma that was formerly blamed for all maladies.

pharmacopea
We enjoyed learning of the provenance and prompting of this detailed 1932 medicinal plant map of the United States—bordered by pharmacologically significant plants from around the world—and the ensuing discussion of the evolution and repackaging of the apothecary’s skill and experience as Big Pharma.
As appears in the map’s call-out box, the public lose sight of the contributions of a trained corps of professional to supplement medical science, whose advances cannot be discounted to be sure, at their peril and it was unwise to place too much faith in synthetic chemistry whose mechanisms can sometimes elicit more guesswork and side-effects than we bargain for. What do you think? Moreover, and perhaps the graver concern, we do ourselves and the profession by conflating traditional wisdom and folk-remedies with snake-oil and superstition—which stakes a claim to legitimacy because of the challenge in knowing where to draw the line.
