Listening for a Drink [via Nina Reznick]

Plant are tuned in to acoustic vibrations, and they can hear when the vibes are good. The roots listen for signals of water to drink, according to scientists.

A new study from the University of Western Australia’s Center for Evolutionary Biology, published in Oecologia on April 5, examined whether plants tune in to sound when seeking water. Plant cognition researchers, led by Monica Gagliano, found that plant root systems travel toward water sources by sensing acoustic vibrations.

In other words, plants respond to the sounds rather than the presence of moisture, as if they can feel sound. The team played water flowing through a sink and a recording of the same sound to common pea plants with roots separated in tubes and examined how the roots responded. The scientists found that root systems did not grow toward the recorded sound but did grow toward the water flowing through a sink. They could distinguish between fake water sounds and the real thing.

“It was…extraordinary and surprising that the plant could actually tell when the sound of running water was a recording and when it was real, and that the plant did not like the recorded sound,” writes Gagliano.

Not only that, when water was available from natural sources—in soil—and was still flowing from the sink, roots grew toward the natural source. This indicates the plant made a choice. “From this we begin to see the complexity of plant interactions with sound in using it to make behavioral decisions,” Gagliano explains.

Until now, it wasn’t clear how plant roots located their water sources when no moisture is in the soil—for example, they will bust through sealed pipes to access the water flowing through them. The researchers believe that plants travel toward water using sonic vibrations initially, but that the roots then make choices, targeting the better source by determining moisture levels.

Their study suggests that soundproofing pipes may protect them from the threat of a tree root invasion, as long as no leaks reveal the water source either.

It also shows that growing things are tuned in, meaning that good sonic vibes might be more important for quality of environmental life than previously considered. Plants could be suffering from effects of acoustic pollution. The scientists emphasized the need for more research on both plant and animal responses to noise, concluding that there’s an “urgent need to better understand the ecological role of sound.”

Cynocephalus the Copycat

An amulet found in Cyprus, in 2011, once comforted an owner who believed in its powers of protection. The artifact is around 1,500 years old and 1.4 inches by 1.6 inches (34.9mm by 41.2mm). On one side is a palindrome written in Greek. This is where a line of letters can be read the same way backward and forwards.

Several Egyptian figures are on the other side. A mummy on a boat is most likely the god Osiris. The god of silence, Harpocrates, sits on a chair. As expected, his right hand is near his lips showing the eternal gesture of seeking quiet. In front of him is the dog-headed Cynocephalus. This is a known scene in Egyptian art. However, things do not quite follow convention. Usually, Cynocephalus’s paws would be raised in worship of Harpocrates, but on the amulet, he mimics the god’s hand sign for silence. Both bear lines resembling bandages as if they, too, are mummies. This is unheard of for Harpocrates who should also have been seated on a lotus, not a stool. Beyond guessing that the creator did not have a good grasp on Egyptian mythology, it remains a puzzling scene.



The Grey Friars Women


The medieval church of Grey Friars was rediscovered in 2012, along with the skeleton of the missing King Richard III, beneath a parking lot in Leicester, England. A year later four more graves turned up. Since it was a monastery, everyone expected to find a few friars or knights.

A few feet away from the king, an ornate lead coffin produced a woman instead. She was elderly, passed away before Richard during the 13th-14th century, and showed signs of high status. Her casket was inside a stone sarcophagus near the high altar. Two middle-aged women in wooden coffins rested in the choir area of the ruins, where the king himself was buried. A fourth female was found in a pit. None of their identities are known. The gender ratio is also surprising. Male burials outstrip females’ in most monastic graveyards in England, up to 20 men for every woman. It is estimated that there are many more graves, but a clear answer will not be forthcoming since most are beneath modern housing.

from Paper by Mark Kurlansky [via Nina Reznick]



Paper made its first appearance in Europe in the 11th century, but was expensive and suffered from poor quality. By the 15th century, it was inexpensive and of good quality, and that dramatically changed the level of Renaissance art:

"Paper created a monumental shift in European art. ... Drawing is a primal urge, ... but drawing only became a standard art form when paper became available. In the case of Europe, this occurred dur­ing the Renaissance, when paper was still a new idea on the Continent. Previously, there had been very little informal use of parchment for art because it was too expensive and too difficult to erase. At first, European paper was also too expensive to be used to dash off a quick sketch and had too low a standing to be used for serious art. But by the late fifteenth century, this had all changed. Paper opened up the possibility of the sketch. Renaissance artists sketched out their work before they drew, painted, or sculpted it -- or, in the case of Albrecht Dürer's woodcuts, carved it. This new ability to not only plan but toy with ideas raised their art to a level not known in the Middle Ages.

Albrecht Dürer, 
Self-Portrait at Thirteen, 1484


"Artists drew and sketched with varying degrees of skill. Leonardo da Vinci was legendary for his skills as a draftsman. Michelangelo, known for his frescoes and sculptures, was equally brilliant as a draftsman­ -- many art historians consider him to have been the greatest draftsman who ever lived -- though most of his drawing was scribbled chaotically on sheets of paper not intended for public view. Both artists used Fab­riano paper at least some of the time.

"Sixteenth-century artist and historian Giorgio Vasari, whose Lives of the Most Eminent Painters, Sculptors, and Architects is the leading source of biographical information on the Italian Renaissance artists, tells the story of a sketch by Michelangelo that was displayed in the Palazzo Medici for art students to copy. Since the sheet, like most of Michelan­gelo's sheets, had a variety of sketches on it, students started tearing off pieces of it, and they became 'scattered over many places.' According to Vasari, those fortunate students who ended up with a remnant treasured it and regarded it as something 'more divine than human.'
Head of a Young Woman -- Da Vinci

"Michelangelo used a great deal of paper, [and] ... almost any piece of paper he used contained a few sketches. A few are finished drawings. A stunning drawing of the resurrection of Christ is also marked with a shopping list. Masterful drawings were folded up, with notes about the banal ephemera of everyday life jotted on the reverse side. ...

"Michelangelo may have been among the first to jot down quick ideas for himself. Some 2,000 letters from and to Michelangelo have also been collected. Letter writing is another practice that blossomed with the widespread use of paper.

"Leonardo da Vinci was notorious in his lifetime for his inability to complete projects. ... Fortunately, there was paper, on which Leonardo could capture his genius. Though he is usually thought of as a painter, only fifteen paintings, some unfinished, have been found, along with two damaged murals. He also attempted some sculpture, though he never finished one piece. But he left behind thirty bound notebooks. Unlike Michel­angelo, he did want people to see this work on paper, including the notes he made in his mirror-image script -- a curious response to being left-handed. He left drawings depicting all kind of inventions, and notes on literature, arts, mythology, anatomy, engineering, and, most of all nature....

"Leonardo also left behind four thousand sheets of drawings of stag­gering beauty. He was the first artist to be recognized for his drawings on paper.
Leonardo's work became the standard for art in Renaissance Florence. Studying art now meant working on paper, learning to draw. Leonardo had learned art that way himself, in the workshop taught by Andrea del Verrocchio. Artists have been trained on paper ever since."



Banksy Hits Again [Via Nina Reznick]

 A Brexit-inspired mural by Banksy showing a metalworker chipping away at a star on the EU flag has appeared in Dover.

The artwork emerged overnight on the Castle Amusements building near the ferry terminal, which connects the UK with mainland Europe.

The mural, which was confirmed by Banksy’s representatives to be a genuine work by the elusive artist, is his first comment on the Brexit vote last year.

The stars of the flag “stand for the ideals of unity, solidarity and harmony among the peoples of Europe”, according to the EU website.

The mural has appeared at a difficult time, when Brexit and the increasingly frosty relationship between Theresa May’s government and the EU over negotiations on Britain’s departure have become central to the general election on 8 June.

Debussy Play Debussy: A Vintage Recording from 1913

The selection is "La soirée dans Grenade" ("Grenada in the evening"), from Debussy's 1903 trio of compositions titled Estampes, or "Prints." Debussy was inspired by the Symbolist poets and Impressionist painters who strove to go beyond the surface of a subject to evoke the feeling it gave off.


A century ago, the great French composer Claude Debussy sat down at a contraption called a Welte-Mignon reproducing piano and recorded a series of performances for posterity.  The machine was designed to encode the nuances of a pianist's playing, including pedaling and dynamics, onto piano rolls for later reproduction, like the one above.

Debussy recorded 14 pieces onto six rolls in Paris on or before November 1, 1913. According to Debussy enthusiast Steve Bryson's Web site, the composer was delighted with the reproduction quality, saying in a letter to Edwin Welte: "It is impossible to attain a greater perfection of reproduction than that of the Welte apparatus. I am happy to assure you in these lines of my astonishment and admiration of what I heard. I am, Dear Sir, Yours Faithfully, Claude Debussy."

Eclipse photos from EarthSky friends [via Pat Francke]




Beverley Sinclair, who saw the eclipse outside Charleston, South Carolina wrote: 
“The skies were very cloudy leading up to totality but, miraculously, slowly 
cleared as totality approached.”


Karl Diefenderfer saw the eclipse in Dillard, Georgia. He wrote: “To witness totality was
one of the most humbling experiences of my life!”


Steven Simmerman, who saw the eclipse from Wilson, Wyoming, wrote:
“Extremely clear sky. Saw shadow bands, leaf lens images, drastic drop in
temperature and light as well. Other celestial objects popped out. I didn’t plan
for the darkness and I lost sight of my camera settings. The flash went off by
itself and I could see the luminescence on my watch numerals.
Overall, an awesome experience!”

 
An animated take on the eclipse experience, by Rob Pettengill, who 
observed in Tarrington, Wyoming. He wrote: “Condensing high-resolution still images
 into a 256-image, color, animated GIF compromises image detail and quality.
The payoff is that you can see the entire 3-hour eclipse play out in about half a minute.”


Gowrishankar Lakshminarayanan caught this image of the diamond ring effect,
with friends watching below, in Boysen State Park, Shoshoni, Wyoming.


Observing from Wyoming, Gowrishankar Lakshminarayanan also caught
the star Regulus in the constellation Leo the Lion, under the eclipsed sun.


Chirag Upreti caught Regulus, too. He wrote: “During totality, the sun’s gorgeous
corona was visible with the unaided eye, and below that lay Regulus the heart of Leo.
The two-and-a-half-minute show was spectacular, magical in every aspect.”

Mathematical secrets of ancient tablet unlocked after nearly a century of study


Dating from 1,000 years before Pythagoras’s theorem, the Babylonian clay tablet is a trigonometric table more accurate than any today, say researchers.

The tablet, known as Plimpton 322, was discovered in the early 1900s in southern Iraq and has long been of interest to scholars.




The four columns and 15 rows of cuneiform – wedge shaped indentations made in the wet clay – represent the world’s oldest and most accurate working trigonometric table, a working tool which could have been used in surveying, and in calculating how to construct temples, palaces and pyramids.
