Around the world—from tundra to tropical forests, and a variety of ecosystems in between—environmental researchers have set up micrometeorological towers to monitor carbon, water, and energy fluxes, which are measurements of how carbon dioxide (CO2), water vapor and energy (heat) circulate between the soil, plants and atmosphere. Most of these sites have been continuously collecting

Energy Department to Invest $16 Million in Computer Design of Materials

The U.S. Department of Energy announced today that it will invest $16 million over the next four years to accelerate the design of new materials through use of supercomputers. Two four-year projects—including one team led by Berkeley Lab — will leverage the Lab’s expertise in materials and take advantage of superfast computers at DOE national laboratories to develop software for designing new functional materials to revolutionize applications in alternative and renewable energy, electronics, and more.

Data Centers Continue to Proliferate While Their Energy Use Plateaus

As the number of data centers continues to increase in the United States, the good news is that they are becoming much more energy efficient. A new report from the Lawrence Berkeley National Laboratory has found that electricity consumption by data centers nationwide, after rising rapidly for more than a decade, started to plateau in 2010 and has remained steady since, at just under 2 percent of total U.S. electricity consumption.

New Mathematics Accurately Captures Liquids and Surfaces Moving in Synergy

A new mathematical framework developed at Berkeley Lab allows researchers to capture fluid dynamics coupled to interface motion at unprecedented detail.

Berkeley Lab researchers in the Computing Sciences Division have developed a new mathematical framework that allows researchers to capture fluid dynamics at unprecedented detail. The work could be used in a range of applications, like optimizing the shape of a propeller blade and the ejection of ink droplets in printers.

Scientists Take a Major Leap Toward a ‘Perfect’ Quantum Metamaterial

Illustration - The wavelike pattern at the top shows the accordion-like structure of a proposed quantum material—an artificial crystal made of light—that can trap atoms in regularly spaced nanoscale pockets. These pockets can be made to hold a large collection of ultracold “host” atoms (green), slowed to a standstill by laser light, and individually planted “probe” atoms (red) that can be made to transmit quantum information in the form of a photon (particle of light). The lower panel shows how the artificial crystal can be reconfigured with light from an open (hyperbolic) geometry to a closed (elliptical) geometry, which greatly affects the speed at which the probe atom can release a photon.

Scientists have devised a way to build a “quantum metamaterial”—an engineered material with exotic properties not found in nature—using ultracold atoms trapped in an artificial crystal composed of light.

A New Spin on Quantum Computing: Scientists Train Electrons with Microwaves

In what may provide a potential path to processing information in a quantum computer, researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave “tuning fork.”

Energy Secretary Ernest Moniz has awarded Berkeley Lab scientists Bill Collins and Greg Bell with DOE Secretarial Honor Awards, which are the department’s highest form of non-monetary employee recognition.

On the Road to Spin-orbitronics

These schematics of magnetic domain walls in perpendicularly magnetized thin films show (a) left-handed and (b) right-handed Neel-type walls; and (c) left-handed and (d) right-handed Bloch-type walls. The directions of the arrows correspond to the magnetization direction.

Berkeley Lab researchers have discovered a new way of manipulating the magnetic domain walls in ultrathin magnets that could one day revolutionize the electronics industry through a technology called “spin-orbitronics.”

Rediscovering Spontaneous Light Emission


LEDs could replace lasers for short-range optical communications with the use of an optical antenna that enhances the spontaneous emission of light from atoms, molecules and semiconductor quantum dots.
