Major advance in artificial photosynthesis poses win/win for the environment
By combining biocompatible light-capturing nanowire arrays with select bacterial populations, a potentially game-changing new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide.

New 'cool roof time machine' will accelerate cool roof deployment
A collaboration led by Berkeley Lab scientists has established a method to simulate in the lab the soiling and weathering of roofing materials, reproducing in only a few days the solar reflectance of roofing products naturally aged for three years. Now this protocol has been approved by American Society for Testing and Materials International as a standard practice for the industry.

New research project to study how tropical forests worldwide respond to climate change
Tropical forests play major roles in regulating Earth's climate, but there are large uncertainties over how they'll respond over the next 100 years as the planet's climate warms. An expansive new project led by scientists from Berkeley Lab aims to bring the future of tropical forests and the climate system into much clearer focus. The project is called the Next Generation Ecosystem Experiments-Tropics, or NGEE-Tropics.

Skin tough
A collaboration of Berkeley Lab and UC San Diego researchers has recorded the first direct observations of the micro-scale mechanisms behind the ability of skin to resist tearing. The results could be applied to the improvement of artificial skin, or to the development of thin film polymers for flexible electronics.

Goodbye, range anxiety? Electric vehicles may be more useful than previously thought
In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles will meet the daily travel needs of drivers longer than commonly assumed. They found that batteries that have lost 20 percent of their originally rated energy storage capacity can still meet the daily travel needs of more than 85 percent of US drivers.

Computer sims: In climatic tug of war, carbon released from thawing permafrost wins handily
There will be a lot more carbon released from thawing permafrost than the amount taken in by more Arctic vegetation, according to new computer simulations conducted by Berkeley Lab scientists.

A better way of scrubbing CO2
Berkeley Lab researchers have discovered a means by which the removal of carbon dioxide (CO2) from coal-fired power plants might one day be done far more efficiently and at far lower costs than today. By appending a diamine molecule to the sponge-like solid materials known as metal-organic-frameworks (MOFs), the researchers were able to more than triple the CO2-scrubbing capacity of the MOFs, while significantly reducing parasitic energy.

New clues about the risk of cancer from low-dose radiation
Berkeley Lab scientists studied mice and found their risk of mammary cancer from low-dose radiation depends a great deal on their genetic makeup. They also learned key details about how genes and the cells immediately surrounding a tumor (also called the tumor microenvironment) affect cancer risk.

Unlocking the key to immunological memory in bacteria
A powerful genome editing tool may soon become even more powerful. Berkeley Lab researchers have unlocked the key to how bacteria are able to 'steal' genetic information from viruses and other foreign invaders for use in their own immunological memory system.

First detailed microscopy evidence of bacteria at the lower size limit of life
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from Berkeley Lab and the University of California, Berkeley. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now.

First direct observation of carbon dioxide's increasing greenhouse effect at the Earth's surface
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory, 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. They attributed this upward trend to rising carbon dioxide levels from fossil fuel emissions.

2015 AAAS Annual Meeting
Berkeley Lab researchers at AAAS
Can more accurate climate models help us understand extreme weather events? What can we expect with the upcoming restart of the Large Hadron Collider and what does the future of accelerators look like? These questions, and the ongoing search for a better battery, are just some of the many presentations by Berkeley Lab researchers at this year's AAAS meeting. And don't forget to stop by our booth (#406) in the Exhibit Hall this week.

From the bottom up: Manipulating nanoribbons at the molecular level
Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties -- such as position-dependent, tunable bandgaps -- that are potentially very useful for next-generation electronic circuitry.
