Design a roller coaster, determine the outcome of bumper car collisions, and more. Ask Dr. Universe How do chameleons change color? When was the light bulb invented? Why can't cats and dogs be friends? Homo erectus - H. erectus is a well known hominid IntroductionThroughout the early years of paleoanthropology, there were only two different species that were attributed to the genus Homo. These included the Neanderthals, and Homo erectus. In the early 1960s, this began to change, and human ancestry seemed to be populated by many different players. Accordingly, erectus is one of the better-known members of genus Homo, especially in terms of its well-established place in paleoanthropology.

The Experimental Food Society Spectacular *rugenius in food+drink , 11:58 From our London based editor, Justine Aw… Some fun highlights from this year’s Experimental Food Society Spectacular exhibition housed in Brick Lane’s Old Truman Brewery! How could we not check out an event that boasted “an awe‐inspiring assemblage of jellymongers, sonic food artists, one‐of‐a‐kind dining conceptualists, cake sculptors, food landscape artists and food magicians”? There were some amazing cakes (including a dodo!)

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing.

Monster octopi with scores of extra tentacles ~ Pink Tentacle - StumbleUpon In nature, it is quite rare to encounter octopi with extra tentacles (or "arms," for the purists), but a pair of aquariums in Japan's Mie prefecture have some extraordinary specimens on hand. The permanent display at the Shima Marineland Aquarium in the town of Shima includes a 96-tentacled Common Octopus (Octopus vulgaris) that weighed 3.3 kilograms (about 7 lbs) and measured 90 centimeters (3 ft) long when it was captured in nearby Matoya Bay in December 1998. Before dying 5 months later, the creature laid eggs, making it the first known extra-tentacled octopus to do so in captivity. All the baby octopi hatched with the normal number of tentacles, but unfortunately they only survived a month. 96-tentacled octopus laying eggs The preserved octopus actually has the normal number of 8 appendages attached to its body, but each one branches out to form the multitude of extra tentacles.

Top 10 Signs Of Evolution In Modern Man Humans Through history, as natural selection played its part in the development of modern man, many of the useful functions and parts of the human body become unnecessary. What is most fascinating is that many of these parts of the body still remain in some form so we can see the progress of evolution. This list covers the ten most significant evolutionary changes that have taken place – leaving signs behind them.

No thanks Repost: Cookie-Cutter Cat Not as Cute as the Name Sounds [This is a repost of an essay I originally published October 27, 2011.] The prehistoric cookie-cutter cat was not as cute as the name suggests. That’s especially true when you consider the fossil felid’s scientific label — Xenosmilus. That roughly translates to “alien knife.”

Strange Science: Dinosaurs and Dragons Despised in the West and revered in the East, dragons have a long history in human mythology. How did the myth start? No one knows the exact answer, but some myths may have been inspired by living reptiles, and some "dragon" bones probably belonged to animals long extinct — in some cases dinosaurs, in others, fossil mammals. Starting in the early 19th century, scientists began to find a new kind of monster, one that had gone extinct tens of millions of years before the first humans evolved.
