7 Things you didn’t know about Ninja Imposing figures in black, hiding in the shadows, and moving about with almost superhuman agility seem like nothing but cool stories told to tourists and movie-goers nowadays, but were once a very real part of feudal Japan. Japanese folklore states that the Ninja descended from a demon that […]

Five completely separate groups of crustaceans independently evolved into what we commonly refer to as “crabs.” This phenomenon is called “carcinization.”

Biological Sciences /

Evolution of crabs – history and deconstruction of a prime example of convergence Compared with the elongate bodies of shrimps or lobsters, crabs are characterised by a compact body organisation with a depressed, short carapace and a ventrally folded pleon. The evolutionary transformation from a lobster-like crustacean towards a crab is called ‘carcinization’ and has

After a Far Side cartoon featured a chimpanzee referring to Jane Goodall as a “tramp”, the cartoonist received a letter from Goodall’s lawyers calling the comic an “atrocity”. Goodall herself later saw the cartoon and loved it, and wrote the introduction to one of the Far Side collections.

Astronomer Harlow Shapley firmly believed that there was only one galaxy in the universe but when he was presented with an evidence that disproved his view, he said “it destroyed his universe.” Then he completely changed his view and devoted his subsequent career in mapping 76,000 galaxies.

Harlow Shapley Harlow Shapley (November 2, 1885 – October 20, 1972) was an American scientist, head of the Harvard College Observatory (1921–1952), and political activist during the latter New Deal and Fair Deal. Shapley used Cepheid variable stars to estimate the size of the Milky Way Galaxy and the Sun’s position within it by using

The Earth’s rotation and speed changes with the weather and geological events. This means atomic time and solar time may not be identical. Sometimes leap seconds are needed for an adjustment. On 31 Dec 2016, a leap second was added, and the time 23:59:60 existed.

Leap second Screenshot of the UTC clock from time.gov during the leap second on December 31, 2016. In the U.S., the leap second took place at 18:59:60 local time on the East Coast, at 15:59:60 local time on the West Coast, and at 13:59:60 local time in Hawaii. A leap second is a one-second adjustment

Not long after Julius Caesar was assassinated, a comet shone for seven successive days. This signified Julius Caesar’s ascension to Godhood, and propaganda for Caesar’s nephew. The comet was described as: “To make that soul a star that burns forever, Above the Forum and the gates of Rome.”

Caesar’s Comet Caesar’s Comet (also Sidus Iulium (“Julian Star”); Caesaris astrum (“Star of Caesar”); Comet Caesar; the Great Comet of 44 BC; numerical designation C/-43 K1) was a seven-day cometary outburst seen in July 44 BC. It was interpreted by Romans as a sign of the deification of recently assassinated dictator, Julius Caesar (100–44 BC).

African elephants often bury dead or sleeping humans or aid them when they are hurt. One woman fell asleep under a tree and woke to find an elephant standing over her gently touching her. As other elephants arrived they buried her under branches. She was found the next morning unharmed.

Elephant cognition Scientists often debate the extent to which elephants feel emotion. Elephants have been one of few species of mammals other than Homo sapiens sapiens and Neanderthals known to have or have had any recognizable ritual around death. Elephants show a keen interest in the bones of their own kind (even unrelated elephants that

If funding remained at 1969 Apollo mission levels, NASA planned to develop such elements as a lunar orbit station in 1978, a lunar surface base in 1980, and a manned mission to Mars in 1981 or 1983

Just another Apollo? Part two In mid-1969, as the Apollo missions were reaching their climax, NASA managers began to plan for the next phase of lunar exploration. This optimistic plan, issued by the Space Task Group, would have had NASA’s funding stay at Apollo levels, and, in a series of steps that followed Apollo, would
