Amoeba Fail! This poor Dictyostelium (colored green) is trying very hard to engulf a mutant yeast cell that is just too large :)

The orange label is on actin filaments : cytoskeletal elements that organize around the edges, ready to close off the phagosome. Myosin motors pull the actin together, like the drawstring of a purse.

Notice the force with which the amoeba ejects the yeast cell when it gives up. Then it tries again , from a different angle. Watch the excess surface membrane being thrown into ruffles before it is quickly absorbed into the cell. Not surprisingly, this video was titled Frustration!

One of the greatest minds of the 20th century, Nikola Tesla, died on this date in 1943
FTA: Nikola Tesla was a polyglot, and along with his native tongue he also spoke Czech, English, French, German, Hungarian, Italian, and Latin.
During his second year of study at Graumltz, Tesla developed a passion for (and became very proficient at) billiards, chess and card-playing, sometimes spending more than 48 hours in a stretch at a gaming table. Tesla by nature required little sleep, claiming to never sleep more than two hours. On one occasion at his laboratory Tesla worked for a period of 84 hours without sleep or rest.
Tesla may have suffered from obsessive-compulsive disorder, and had many unusual quirks and phobias. He did things in threes, and was adamant about staying in a hotel room with a number divisible by three. Tesla was physically revolted by jewelry, notably pearl earrings. He was fastidious about cleanliness and hygiene, and was by all accounts mysophobic.
Tesla was obsessed with pigeons, ordering special seeds for the pigeons he fed in Central Park and even bringing injured ones into his hotel room to nurse them back to health. Tesla was an animal-lover, often reflecting contentedly about a childhood cat, "The Magnificent Mačak." Tesla never married. He was celibate and claimed that his chastity was very helpful to his scientific abilities. Nonetheless there have been numerous accounts of women vying for Tesla's affection, even some madly in love with him. Tesla, though polite, behaved rather ambivalently to these women in the romantic sense.
Tesla was prone to alienating himself and was generally soft-spoken. However, when he did engage in a social life, many people spoke very positively and admiringly of him. Robert Underwood Johnson described him as attaining a "distinguished sweetness, sincerity, modesty, refinement, generosity, and force." His loyal secretary, Dorothy Skerrit, wrote: "his genial smile and nobility of bearing always denoted the gentlemanly characteristics that were so ingrained in his soul." Tesla's friend Hawthorne wrote that "seldom did one meet a scientist or engineer who was also a poet, a philosopher, an appreciator of fine music, a linguist, and a connoisseur of food and drink."

Scurvy, the A140 road and parsnips are three of the things that do not describe me. Funambulist, on the other hand, neither. Thank you.
