Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals, which is most therapies rely on drugs that block chemical signals. Scientists can now show, however, for the first time, that direct physical force can also change the way cellular proteins conduct chemical activity.

An analysis of more than 70,000 galaxies by physicists in the U.S. and Switzerland demonstrates that the universe—at least up to a distance of 3.5 billion light years from Earth—plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.

In the short time that the image of Fomalhaut—a star with a Jupiter-sized planet imaged by Hubble Space Telescope—was published by UC Berkeley’s Paul Kalas, it has become an icon. Why? The 2008 image was the first visible-light picture of an extrasolar planet.

In research that gives literal meaning to the term "power suit," Univ. of California, Berkeley, engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles.

Fifty years ago, the first optical laser was built. And despite contention about whether Thomas Maiman or Gordon Gould actually built the first laser, the initial idea can be credited to Charles Townes and Arthur Schawlow for their 1958 publications theorizing the possibly of an optical laser operating on the principles of their patented maser, an amplifier for acoustic signals.

Researchers at the Univ. of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive.

There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. A lead-free alternative to the current crop of piezoelectric materials has been identified by researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Univ. of California (UC), Berkeley.

By attaching light-sensitive switches to certain nerve cells
in fish larvae, researchers have been able to stimulate the twitch of the tail
that’s common to larvae that detect light. Because humans have similar cells,
the idea that optogenetic tools can turn on or off groups of cells with the
flip of switch may have great impact on certain types of medicine or therapy.

Researchers at the Univ. of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule. This breakthrough breaks new ground in the field of optics. The UC Berkeley team not only successfully squeezed light into such a tight space, but found a novel way to keep that light energy from dissipating as it moved along, thereby achieving laser action.

Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations.
