signal-to-noise ratio

Mathematical modelling on the part of a research team at Boston University have produced a muting, sound muffling device (really more of a function than a gadget) that deflects virtually all unwanted acoustic smog back towards its source, instead of absorbing it—the usual method of dealing with errant noises.
The sound is channelled from its source along a tube where it’s silenced on the other end by this echoing ring with no membrane to obscure the view (or non-carrier-wave flow of air) back and beyond and could be scaled up or down to make offices, apartments and other shared spaces a bit more tranquil and adjustable, perhaps even as earplugs. As much as I’d like to be able to press a mute button sometimes and relish my peace and quiet, I’m a little afraid we’d grow overly sensitive to the general din of background noise, cushioned by our filters, and we’d wither without them.

While working at CERN, having helped established the world’s then largest networked node of computers, Tim Berners-Lee (previously here and here) recognised the opportunity to merge hypertext with their internet, in efforts to make his job easier and more transparent for his collaborators.
On this day in 1989, he submitted his proposal to the laboratory’s communications office, whose abstract contained the concept of the world-wide web, later distributed and received as “vague but exciting,” the abstract linking disparate but already existing technologies in ways no one else had though to beforehand. The image is the coat of arms for the British Computer Society—of which Berners-Lee is a distinguished fellow, and was founded in 1956 as a professional body and learned association for the advancement of computer science, receiving a royal charter in 1984.

Via the always wonderful and inspiring Nag on the Lake we are introduced to a shrub called Selaginella lepidophylla—a type of resurrection plant—that can cope with the arid and punishing conditions of its native habitat, the deserts of Chihuahua, and survive unscathed near complete desiccation.
During periods of drought—and researchers are looking into how they might reactivate the same dormant genes in food crops to make them sturdier under dry conditions—the plant, also known as the (False) Rose of Jericho, curls up into a ball when dry and unfurls its fronds upon re-hydration and has evolved another clever trick as has its North African cousin—Anastatica hierochuntica, the (True) Rose of Jericho—and can form tumbleweeds to be whisked away to a more favourable location. Since ancient times, farmers (and hucksters) have recognised resurrection plants as vegetable hygrometer to predict oncoming rain. See a time-lapse of the thirsty plant getting a drink at the link above.

Never failing to at least furnish if not revive a moribund term from the annals of the English language, the Oxford English Dictionary sometimes also often delivers the resonant, relevant and perhaps what may hit a little too close to home—as with this word which last appeared in an 1881 article from our Manchester Guardian: “‘Scripturiency’ appears to vary greatly in different nations. The United States claim 2,800 of these medical authors; France and her colonies, 2,600…” The obsolete word coined in the mid-seventeenth century refers to a compulsion for writing which leads to the urgent publication of the trivial and inferior.

Via the always brilliant Nag on the Lake, we discover that filmmaker Daniel McKee has selected, identified and carefully arranged over two thousand flags, banners and ensigns from all ages into a montage with fluid transformations as the vexillological elements (see also here, here, here and here) blend into one another synchronised to the sonatas of Ludwig van Beethoven.
