Rogue waves—individual, isolated waves far larger than the surrounding waves—were reported for centuries by sailors. But their stories of massive walls of water appearing in the open ocean were not corroborated until 1995 when a rogue wave struck an offshore platform. How these giant waves form is still under active research, but one leading theory is that nonlinear interactions between waves allow one wave to sap energy from surrounding waves and focus it into one much larger, short-lived wave. I first learned of rogue waves during a seminar in graduate school. At the time, this idea of nonlinear focusing had only been explored in simulation, but a few years later a research group was able to demonstrate the effect in a wave tank, as shown in the video above. Wait for the end, and you’ll notice how the rogue wave that takes down the ship is much larger than its predecessors. For more on rogue waves and their mind-boggling behavior, be sure to check my previous post on the subject. (Video credit: A. Chabchoub, N. Hoffmann, and N. Akhmediev)

For the zoological illustration final, we were required to illustrate a fully fleshed out mammal as well as the full skeleton and musculature for a region of the body. I wanted to focus my project on the anteater’s feeding habits so the pose I drew was of the anteater digging so…
Scarlet Tiger Moth (Callimorpha dominula)
…a colorful species of Arctiid tiger moth (Arctiinae) which occurs in Southern Europe and the Middle East, ranging from Turkey to northern Iran. Adult scarlet tiger moths are day flying and will take nectar. Their larvae, on the other hand, feed mostly on comfrey (Symphytum officinale). Three different color morphs of C. dominula exist: One with yellow hindwings and body, one with red hindwings, and one with extended black on its hindwings.
These nightmarish images feel like scenes from a B-movie, but they’re really photos of a powerful traveling art installation by Colombian artist Rafael Gómezbarros entitled Casa Tomada (“Seized House”). Giant ant sculptures swarm across urban exteriors and gallery walls. As if the idea of monstrous ants wasn’t already freaky, these 2-foot-long specimens feature tree branches for legs and segmented bodies made of joined pairs of fiberglass resin skulls and fabric. These hair-raising urban interventions are meant to draw attention to the uprooting, immigration and forced displacement of peasants and migrant workers in Latin America.
"When placed on the facades of government buildings and blank gallery walls alike, the ants give off a chilling sense of foreboding and encroachment. By placing them in swarms, Gómezbarros makes the insects even more strikingly representative of the peasants displaced by war and strife in Gómezbarros’ native Colombia."
