Electric fish diverging Carl Hopkins Although these fish look alike and have the same DNA genetic makeup, they have very different electrical signals and will only mate with fish that produce the same signals. Cornell researchers believe that these different electrical signals are the fishes' first step in diverging into separate species. Avoiding quicksand along the banks of the Ivindo River in Gabon, Cornell neurobiologists armed with oscilloscopes search for shapes and patterns of electricity created by fish in the water.

The Borg of the Microbes Takes Up . . . Farming? You are witnessing one of nature's most incredible migrations that never gets shown on the Discovery Channel. Believe it or not, each one of those little dots is a solitary amoeba. But not for long. Note: This post contains a prize inside! It will await those patient enough to dig to the bottom. : ) The Borg of the Microbes Takes Up . . . Farming?

previous home next PDF Michael Fowler, University of Virginia A Magnetic Puzzle… Suppose we have an infinitely long straight wire, having a charge density of electrons of –λ coulombs per meter, all moving at speed v to the right (recall typical speeds are centimeters per minute) and a neutralizing fixed background of positive charge, also of course λ coulombs per meter. The current in the wire has magnitude I = λv (and actually is flowing to the left, since the moving electrons carry negative charge).

Hot springs microbe yields record-breaking, heat-tolerant enzyme Bioprospectors from the University of California, Berkeley, and the University of Maryland School of Medicine have found a microbe in a Nevada hot spring that happily eats plant material – cellulose – at temperatures near the boiling point of water. In fact, the microbe’s cellulose-digesting enzyme, called a cellulase, is most active at a record 109 degrees Celsius (228 degrees Fahrenheit), significantly above the 100℃ (212℉) boiling point of water. A 94°C geothermal pool, with a level-maintaining siphon, near Gerlach, Nevada. Hot springs microbe yields record-breaking, heat-tolerant enzyme

April 10, 2014 Despite estimates that there are trillions of planets in the universe, one scientist argues that we are effectively alone. The Science of Self April 02, 2014 Jennifer Ouellette, author of the new book "Me, Myself, and Why: Searching for the Science of Self," shares how physics and neurobiology intersect over the idea of emergence. Beating the Game of Go March 26, 2014 Chess masters have been beaten by computers, but machines still can't beat the best Go players.

Quick evolution leads to quiet crickets Resource library : Evo in the news : Quick evolution leads to quiet cricketsDecember 2006, updates added June 2008 and June 2011 Attack of the flesh-eating parasitoid maggots!! Mutant mute crickets run rampant in tropical paradise!! The headlines may sound like a trailer for a cheap horror flick — but in fact, these sensationalist sound bites accurately describe the situation on the Hawaiian island of Kauai. The "flesh-eating parasitoid maggots" are the offspring of the fly, Ormia ochracea, which invaded Hawaii from North America, and the mutant crickets are the flies' would-be victims.

Gliese 581d is the outlying planet in the Gliese 581 system, and orbits its parent star every 66.8 days. It may be covered by a large and deep ocean and is the first serious 'waterworld' candidate discovered beyond our Solar System. Credit: ESO/L. Calçada

The Big Chandra Picture In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format.

Steve Fisch Howard Chang and his team have discovered how cells decide which proteins they will tend to produce. If a big bunch of your brain cells suddenly went rogue and decided to become fat cells, it could cloud your decision-making capacity a bit. Fortunately, early in an organism’s development, cells make firm and more-or-less permanent decisions about whether they will live their lives as, say, skin cells, brain cells or, well, fat cells. researchers discover molecular determinant of cell identity researchers discover molecular determinant of cell identity

Quantum mechanics lays out a set of mind-bending rules on how very small things move and behave, such as their ability to absorb energy only in discrete amounts (or quanta) and be in two different states at the same time. Although, so far, quantum effects have been observed primarily in molecules, atoms, and subatomic particles, physicists have been putting much effort into observing quantum mechanics in systems closer to human scale. Such efforts are starting to pay off. Breakthrough of the Year: Bridging the Quantum and the Classical Worlds

Langton's ant Langton's ant after 11000 steps. A red pixel shows the ant's location. Langton's ant is a two-dimensional Turing machine with a very simple set of rules but complicated emergent behavior. It was invented by Chris Langton in 1986 and runs on a square lattice of black and white cells.[1] The universality of Langton's ant was proven in 2000.[2] The idea has been generalized in several different ways, such as turmites which add more colors and more states.
