Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. Researchers, led by Berkeley Lab scientists, measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America.
Capturing the spirit, purpose, and distinction of Berkeley Lab in video in less than 2 minutes is no small challenge, but it’s necessary given the viewing preferences of today’s audiences. Berkeley Lab’s first “who-we-are” video not only beat the clock, but also, we hope, leaves viewers hungry to know more.
In March, when researchers flip the switch to the refurbished Large Hadron Collider, scientists all over the world will be watching. Physicists expect the higher-energy accelerator will build on the 2012 discovery of the Higgs particle and crack open even more mysteries of the universe.
Until recently, it was often difficult for private industry to take advantage of Berkeley Lab’s resources. That has changed with CalCharge, a unique public-private partnership uniting the California Bay Area’s emerging and established battery technology companies with critical academic and government resources.
Berkeley Lab researchers at the Molecular Foundry have uncovered key details in the process by which bacterial proteins self-assemble into a protective coating, much like chainmail armor. This process can be a model for the self-assembly of 2D and 3D nanostructures.
Metamaterials—artificial nanostructures engineered with electromagnetic properties not found in nature—offer tantalizing future prospects such as high resolution optical microscopes and superfast optical computers. Now, Berkeley Lab researchers have shown that it is possible to predict the nonlinear optical properties of metamaterials.
A Berkeley Lab led team has used an external optical antenna to greatly enhance the spontaneous emission of light from a semiconductor nanorod. This advance opens the door to LEDs that can replace lasers for short-range optical communications, including optical interconnects for microchips.
The National Museum of American History’s “Year of Innovation” showcases the battle between Alexander Graham Bell and Thomas Edison to develop sound-capturing machines, much like the modern tug-of-war between Apple and Microsoft. Visitors can hear these early sounds thanks to research by Berkeley Lab’s Carl Haber and Earl Cornell.
Since the polio vaccine was introduced in the 1950s, one of the most dreaded diseases in history has been all but eradicated. Are there other scientific breakthroughs that could have an equally transformative impact on global human development, and if so, what are they?
Berkeley Lab’s quantum dots have not only found their way into tablets, computer screens, and TVs, they are also used in biological and medical imaging tools, and now Paul Alivisatos’ lab is exploring them for solar cell as well as brain imaging applications.
