Virus-based piezoelectric energy generator

Lawrence Berkeley National Laboratory scientists have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. The milestone could lead to tiny devices that harvest electrical energy from the vibrations of everyday tasks. The first part of the video shows how Berkeley Lab scientists harness the piezoelectric properties of the virus to convert the force of a finger tap into electricity. The second part reveals the "viral-electric" generators in action, first by pressing only one of the generators, then by pressing two at the same time, which produces more current.

Cells Forming Acini

Berkeley Lab researchers have discovered a rotational motion in human breast cells that continues through mitosis and enables the cells and their progeny to form sphere-shaped acini.

Surface Tension

Surface tension in the kitchen sink. At Berkeley Lab's Molecular Foundry, scientists study surface tension to understand how molecules "self-assemble". The coin trick in the video uses the re-arrangement of water molecules to seemingly create order out of disorder. The same principle can be used to create order in otherwise hard-to-handle nano materials. Scientists can then transfer these ordered materials onto surfaces by dipping them through the air-water interface, or (as we've recently shown) squeeze them so that they collapse into the water as two-molecule-thick nano sheets. http://newscenter.lbl.gov/feature-stories/2011/10/17/shaken-not-stirred/

Vibrational Coupling

By homing in on the distribution patterns of electrons around an atom, a team of scientists with Berkeley Lab's Molecular Foundry showed how certain vibrations from benzenethiol cause electrical charge to "slosh" onto a gold surface (left), while others do not (right). The vibrations that cause this "sloshing" behavior yield a stronger SERS signal.

RNA-exporting machine in action

A tiny motor tasked with one of nature's biggest jobs is now better understood. The molecular machinery that helps export messenger RNA from a cell's nucleus has been structurally mapped at the Advanced Light Source, a synchrotron located at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). In this simulation, Gle1 (yellow) binds Dbp5 (green and blue-grey) causing Dbp5 to release RNA (orange). The movie begins with Dbp5 bound to RNA and then transitions to the Gle1-Dbp5 state, the step that jettisons RNA. The simulation then plays in reverse to mimic RNA and ATP dependent closing of Dbp5 and release of Gle1 (Movie courtesy of Karsten Weis's and James Berger's labs).

Biotechnology at the Cutting Edge - Keasling

Jay Keasling, Berkeley Lab ALD for Biosciences and CEO of the Joint BioEnergy Institute, appears in a video on biotechnology at the Smithsonian's National Museum of American History. The video is part of en exhibit titled "Science in American Life," which examines the relationship between science, technology, progress and culture through artifacts, historical photographs and multimedia technology.

Assembling GRETINA

GRETINA is the most sensitive gamma-ray detector ever built for studies of the nucleus, including how the natural elements were made in stars and supernovae, and the properties of artificial superheavy elements. GRETINA, now being assembled at Berkeley Lab's 88-Inch Cyclotron, is the first stage of GRETA, the even more powerful Gamma-Ray Energy Tracking Array.

A Flight Through the Universe, by the Sloan Digital Sky Survey

This animated flight through the universe was made by Miguel Aragon of Johns Hopkins University with Mark Subbarao of the Adler Planetarium and Alex Szalay of Johns Hopkins. There are close to 400,000 galaxies in the animation, with images of the actual galaxies in these positions (or in some cases their near cousins in type) derived from the Sloan Digital Sky Survey (SDSS) Data Release 7. Vast as this slice of the universe seems, its most distant reach is to redshift 0.1, corresponding to roughly 1.3 billion light years from Earth. SDSS Data Release 9 from the Baryon Oscillation Spectroscopic Survey (BOSS), led by Berkeley Lab scientists, includes spectroscopic data for well over half a million galaxies at redshifts up to 0.8 -- roughly 7 billion light years distant -- and over a hundred thousand quasars to redshift 3.0 and beyond.
