Baby Brains are Wired For Math

Next time someone complains about arithmetic being hard, math lovers can defend themselves by saying even a six-month-old can do it. Through monitoring the brains of infants, researchers confirmed that infants as early as six months in age can detect mathematical errors, putting to rest a debate that has been...

Ties That Bind Atoms Weaker Than Thought

A fundamental force that holds electrons inside atoms and governs how charged particles and light interact is a little weaker than previously thought, scientists reported today. The strength of electromagnetic force, one of the four fundamental forces of nature, is specified through a value known as the fine structure constant.?...

Lost Dimension Yields Accidental Discovery

Using strong magnets and a pigment developed by ancient Chinese warriors, scientists turned a three-dimensional system into one with just two dimensions. The transformation's discovery was accidental, but it provides physical evidence for several theories and might help scientists build faster computers. Our three-dimensional world gives us three options for...

Record Set for Hottest Temperature on Earth: 3.6 Billion Degrees in Lab

Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit. This is hotter than the interior of our Sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say. They don't know how...

Feds Lose a Few Neutrinos, Gain Some Information

Somewhere between Illinois and Minnesota, the federal government lost some neutrinos. No matter. These invisible elementary particles are ubiquitous in the universe. Neutrinos are incredibly elusive. They rarely interact with matter. They can pass right through you with ease and even through the entire Earth. This makes studying neutrinos very...

Small World: Quantum Identity Crisis Observed

A quantum enigma has been put to the test once again, but this time physicists have made the experiment smaller than it has ever been. The classic double-slit experiment tests the behavior of light, electrons, atoms and some molecules as both particle-like and wave-like, a mysterious duality that has intrigued...

MIT Researchers Improve 'Tractor Beam'

CAMBRIDGE, Mass. (AP) — Taking up the sci-fi staple of tractor beams,'' scientists have developed a way to use light to grab and move minuscule particles on a microchip. The research could lead to fine-grained biological sensors and other precisely built nanoscale devices. The work by Massachusetts Institute of Technology...

Nobel Prize Winners Live Longer

Winners live longer, at least when it comes to the Nobel Prize, new research shows. An analysis of 524 nominees for the Nobels in physics and in chemistry between 1901 and 1950 showed that the group’s 135 winners lived about two years longer than the also-rans. The finding points to...

Is Einstein the Last Great Genius?

Major breakthroughs in science have historically been the province of individuals, not institutes. Galileo and Copernicus, Edison and Einstein, toiling away in lonely labs or pondering the cosmos in private studies. But in recent decades — especially since the Soviet success in launching the Sputnik satellite in 1957 — the...

The Top 10 Mad Scientists

Albert Einstein He's certainly got the mad scientist hair thing down. One of the last century's most celebrated scientists, Albert Einstein turned physics on its head with his theories of relativity, and made enormous contributions to the fields of gravitation and quantum theory. He also liked to take his sailboat...

Physicist: Studying Lizards Since Age 5

Georgia Tech physicist Daniel Goldman recently helped figure out how sandfish — small lizards with smooth scales — move rapidly underground through desert sand. In this first thorough examination of subsurface sandfish locomotion, he and his colleagues used high-speed X-ray imaging to visualize sandfish, formally called Scincus scincus, burrowing into...

Deer Disoriented by Power Lines

To aesthetes, high-voltage power lines are a blight on the rural landscape. But zoologists at the University of Duisburg–Essen in Germany welcome them as a tool for testing the power of large ruminants to perceive Earth's magnetic field. Last year, a team led by Hynek Burda and Sabine Begall discovered...

World's Smallest Light Bulb Created

Some bright researchers say they've created the world's smallest incandescent lamp, so teeny it's invisible except when lit. The lamp's filament is just 100 atoms wide. It is made from a single carbon nanotube. When lit, the itty bitty bulb can be seen with the unaided eye as a point...

The Truth about Angels, Demons and Antimatter

An antimatter explosion threatens to level the Vatican in the movie adaptation of the thriller Angels and Demons, but real-world physicists are unfazed by this plot. The story features Da Vinci Code hero Robert Langdon racing to recover an antimatter capsule stolen from the CERN particle physics facility in Switzerland....

Watchmen: The Science of Dr. Manhattan

Among all the characters populating the Watchmen film, the glowing, blue figure of Dr. Manhattan stands out as a god-like being that is seemingly beyond comprehension. Yet when filmmakers approached the character, it was essential to comprehend as much as possible about Dr. Manhattan and his strange powers. So they...
