New research on spider species suggests that their inverted lifestyle is energy efficient

Scientists in Spain and Croatia have found that certain spider species that feed, breed and travel upside-down are more energy efficient because of it. For the spiders, it turns out, walking is more of a swing—they use gravity to their advantage. They effectively act as a pendulum, and require less muscle mass in the legs to move themselves forward.
You're unique. Aren't you? One of the more creative hypotheses surrounding quantum mechanics posits the exact opposite. Though we can readily see only one world, quantum mechanics says that when we're not observing the particles that make up that world, those particles exist in multiple places at once. There are many theories that attempt to grasp what this means, but one of the most tantalizing is Hugh Everett's multiverse concept.
An unfortunate rodent takes a jog around his wheel and gets a physics lesson

Tic, the unfortunate hamster in this video, loses his footing while getting some exercise and gets pulled into the spin cycle, completing nearly 12 revolutions in about four seconds before ignominiously dropping out of the wheel. However, while Tic may be bewildered by what happened during his morning training session, we need not be.
Why does he get pulled into the spin? How does he remain in orbit for 12 rotations before falling off of the wheel? How does he finally escape? These are the questions we will address for Tics sake.
While the stars bask in glitz, the unsung heroes of today's effects-laden blockbusters continue to work on one of the linchpins of CG graphics: realistic water

New York City has just been destroyed by a 40-foot-tall deluge. Pirates battle around a giant, violent whirlpool. Without years of work by the 2007 Scientific and Technical Oscar winners, none of those images would have made it to a computer—and then a multiplex—near you.

For any vehicle—airplane or car—to fly, there needs to be some force pushing it up so that it can overcome gravity. Airplane wings are specifically designed to create just such a force. As a plane moves forward, the wings push air down, and because for every action there's an equal and opposite reaction, this action creates an upward force on the wing, called lift.
Spiderman, Batman, the Fantastic Four, Ironman—seems like every time we go to the movies, there's some guy in a unitard saving the world with acts of unnatural physics. We realize that these are works of fantasy, so we don't get too upset when the science portrayed in them comes from some alternative universe.

As we reach the close of the summer blockbuster season, reports of a recent paper by two professors at the University of Central Florida recently caught our eye. In it, the physicists Costas Efthimiou and R.A. Llewellyn assert that movies are making their students dumber.
Suddenly the U.S. isn't the center of the physics universe. The answer: build the International Linear Colliderâ€”one of the most powerful (and expensive) pieces of equipment on Earth

When the world´s biggest particle accelerator, the Large Hadron Collider, opens next year near Geneva, the focal point of the high-energy physics world will shift from U.S. soil for the first time in half a century. Bummer, indeed. But America´s brightest are busy devising a rescue plan. In April, a panel of U.S.
Ice is supposed to float, but with a little heavy water, you can make cubes that sink

Want a surefire bet for your next cocktail party? First, tell your guests
that aquatic life-at least in temperate
climates-depends largely on the fact
that ice floats. If it sank, lakes would freeze solid instead of forming an
insulating layer of ice on top, killing all the fish. Now bet that you can
magically make an ice cube sink. Grab one from a glass of special cubes

A baseball zooms through clouds, straight through a wall and into the waiting hand of actor Adam Smith, who is tricked out like a magician, complete with wand, tuxedo and top hat. "How do you do it?" Smith asks conspiratorially. "You just need a small enough ball, of course." But Smith isn´t really explaining a magic trick. He´s talking nanotech, in the new short film When Things Get Small.
