Latin Woody Meets Mrs. Basher
Animals are able to communicate in the realm of sound with much more complexity and nuance than scientists had suspected.
• Strawberry rootlets will grow toward the sound of running water, even where there is no moisture gradient.
• There are distinctive patterns in elephant vocalizations that correspond whether the elephant is in the presence of a friendly or unfriendly human, an adult human or a child, or a male or female.
• Owl hoots contain markers identifying both the speaker and the listener.
• A researcher using a voice-recognition program for bats vocalizations found that adults lower the pitch of their squeaks when they're communicating with babies, the opposite of us humans. Our baby talk is typically higher in pitch.
• Most of us have assumed that male peacock displays were sending primarily visual signals, but in fact there's also strong acoustic messaging in the infrasound range, to which females are strongly attuned. What precise information is contained in the feather-shaking display is just beginning to be deciphered.
This work raises profound philosophical and ethical issues, arising from the fact that machine systems can generate sounds that animals clearly understand and respond to, even though we can't recognize those nuances with our own ears. Should we use machine-generated animal sounds to send specific messages to animals, such as warnings, greetings, or invitations?

Why Rembrandt Declared Bankruptcy
But he lost his fortune primarily by spending too much on rare and costly things, including musical instruments, weapons, paintings (including his own), prints, animal specimens, shells, corals, and plaster busts.
Two Tugs Dockside
In Australia an unusual society of octopuses has congregated in Jervis Bay, which observers have dubbed "Octopolis."
Octopuses are normally relatively solitary, so this tendency to group together is not fully understood.
Marine biologist Peter Godfrey-Smith reports that he's noticed a lot of "ornery" behavior that resembles fighting, boxing, bullying, and even shooting shell projectiles underwater. He's not completely sure if this is just territorial squabbling or something else.

Russell Flint on Color Harmony
In his book Water-Colour for Beginners Sir Frances Russell Flint warned that a painting will lack color harmony if it has too many colors in it. He said:
"You must aim at getting tone and harmony in your work, although it may not be easy. All pictures may be divided into masses of bright color or light, medium-strength color, and shadows. It may be difficult to trace the exact places where they occur in a picture, but they are there all the same. It is obvious that when you are working out of doors on a bright sunny day all the colors will be strong and bright in tone, and even the shadows and middle tints will be strong too. The opposite occurs on a dull day, when the whole scene is changed to one of low tone, when both colors and shadows will be soft and subdued. In each case the colors will harmonize and all complement each other in tone. Mix the colors of these two scenes together and the result is a discordant picture which will be unnatural and unbalanced."
