A string of recent discoveries in astronomy has left scientists with an unsettling realization: The stuff we know and understand makes up less than 5 percent of the universe.

Today, physicists conducting the BaBar experiment at the Stanford Linear Accelerator Center (SLAC), a Department of Energy laboratory operated by Stanford University, announced exciting new results demonstrating a dramatic difference in the behavior of matter and antimatter.

If the laws of physics were precisely the same for matter and antimatter, you wouldn't be reading this. All matter, as we know it, would have been converted into light after the Big Bang.

The speed of magnetic recording – a crucial factor in a computer's power and multimedia capabilities – depends on how fast one can switch a magnet’s poles.

The physicists of antiquity called it one of nature's fundamental elements; third-graders know its chemical formula; and all known forms of life need it to exist. Yet what water really is – at least in its liquid form – is...

"The light shines brilliantly these days at the Stanford Synchrotron Radiation Laboratory (SSRL). The start up of SSRL's new synchrotron light facility, SPEAR3, guarantees a world-class program in x-ray science for years to come," said U.S. Secretary of Energy Spencer...

Batavia, Ill.—The worldwide particle physics community today (August 12) launched Interactions.org, a new global, Web-based resource developed to provide news, high-quality imagery, video and other tools for communicating the science of particle physics.

Physicist Antimo Palano representing the BABAR experiment presented the evidence for the identification of a new subatomic particle named Ds (2317) to a packed auditorium on Monday 28th April at the Department of Energy's Stanford Linear Accelerator Center (SLAC).

Transmit 6.7 Gigabytes of data — the data equivalent of 4 hours of DVD-quality movies — across 7000 miles in less than a minute? Can do.

Physicist Fred Kavli and the Kavli Foundation have pledged $7.5 million to establish an institute that will focus on recent developments in astrophysics, high-energy physics and cosmology.
