Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Lawrence Berkeley National Laboratory climate scientist Michael Wehner was able to complete a run in just three months. Not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms.
Does synthetic biology hold the key to manned space exploration of the moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world’s most effective anti-malaria drug, and to develop clean, green and sustainable alternatives to gasoline, diesel and jet fuels. In the future, synthetic biology could also be used to make manned space missions more practical.
Every day, some of your cells stop dividing, and that’s a good thing. Cells that proliferate indefinitely are immortal, an essential early step in the development of most malignant tumors. Despite its importance in cancer, the process of cell immortalization is poorly understood. That’s because scientists have lacked a good way to study immortalization in human cells as it occurs during cancer progression.

Researchers with Berkeley Lab and the Univ. of California (UC) Berkeley have invented a simple, one-step process for producing nanopores in a graphene membrane using the photothermal properties of gold nanorods.
Ever walked into a hotel room and smelled old cigarette smoke? While the last smoker may have left the room hours or even days ago, the lingering odors are thanks to thirdhand smoke. Scientists at Lawrence Berkeley National Laboratory, who have made important findings on the dangers of thirdhand smoke and how it adsorbs strongly onto indoor surfaces, have published a new study assessing the health effects of thirdhand smoke constituents.
Scientists have identified a mechanism that could be a big contributor to warming in the Arctic region and melting sea ice. The research was led by scientists from Lawrence Berkeley National Laboratory. They studied a long-wavelength region of the electromagnetic spectrum called far infrared. It’s invisible to our eyes but accounts for about half the energy emitted by the Earth’s surface. This process balances out incoming solar energy.
If you can uniformly break the symmetry of nanorod pairs in a colloidal solution, you’re a step ahead of the game toward achieving new and exciting metamaterial properties. But traditional thermodynamic-driven colloidal assembly of these metamaterials, which are materials defined by their non-naturally-occurring properties, often result in structures with high degree of symmetries in the bulk material.
A significant breakthrough in laser technology has been reported by Lawrence Berkeley National Laboratory and the Univ. of California, Berkeley. The team of scientists have developed a unique microring laser cavity that can produce single-mode lasing even from a conventional multi-mode laser cavity.
Imagine being able to precisely control specific tissues of a plant to enhance desired traits without affecting the plant’s overall function. Thus a rubber tree could be manipulated to produce more natural latex. Trees grown for wood could be made with higher lignin content, making for stronger yet lighter-weight lumber.
In the on-going effort to develop advanced biofuels as a clean, green and sustainable source of liquid transportation fuels, researchers at the U.S. Dept. of Energy’s Joint BioEnergy Institute have identified microbial genes that can improve both the tolerance and the production of biogasoline in engineered strains of Escherichia coli.
When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding of a diverse set of phenomena. When the solid surface is charged, it can drive further changes in the interfacial liquid. However, elucidating the molecular structure at the solid-liquid interface under these conditions is difficult.
Though it garners few headlines, carbonic acid, the hydrated form of carbon dioxide, is critical to both the health of the atmosphere and the human body. However, because it exists for only a fraction of a second before changing into a mix of hydrogen and bicarbonate ions, carbonic acid has remained an enigma. A new study has yielded new information about carbonic acid with important implications for geological and biological concerns.
Using extremely faint light from galaxies 10.8-billion light-years away, scientists have created one of the most complete, 3-D maps of a slice of the adolescent universe. The map shows a web of hydrogen gas that varies from low to high density at a time when the universe was made of a fraction of the dark matter we see today.
Lithium-ion batteries are popular, but have limitations in energy density, lifetime and safety. One alternative is Mg-ion batteries. Researchers at Lawrence Berkeley National Laboratory ran a series of computer simulations that suggest that performance bottlenecks experienced with Mg-ion batteries to date may not be so much related to the electrolyte itself, but to what happens at the interface between the electrolyte and electrodes.
A new study by scientists from The Scripps Research Institute, Lawrence Berkeley National Laboratory and other institutions suggests a cause of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. The team's work supports a common theme whereby loss of protein stability leads to disease.
Imagine being able to tune the properties of a solid material just by flashing pulses of light on it. That is one potential payoff of electrons and atoms interacting with ultrashort pulses of light. The technology of ultrafast spectroscopy is a key to understanding this phenomenon and now a new wrinkle to that technology, observations of electron self-energy, has been introduced by Lawrence Berkeley National Laboratory researchers.
By combining data from two high-energy accelerators, nuclear scientists from Lawrence Berkeley National Laboratory and colleagues have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, “perfect fluid” that give clues to the state of the young universe just microseconds after the big bang.
Microbes have an amazing ability to feed on plant biomass and convert it into other chemical products. Tapping into this talent has the potential to revolutionize energy, medicine, environmental remediation and many other fields. The success of this effort hinges in part on metagenomics, the emerging technology that enables researchers to read all the individual genomes of a sample microbial community at once.
Certain primordial stars—those between 55,000 and 56,000 times the mass of our sun, or solar masses—may have died unusually. In death, these objects—among the universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy. That is the lure of artificial photosynthesis in which the electrochemical reduction of carbon dioxide is used to produce clean, green and sustainable fuels.
A new report prepared by analysts from Lawrence Berkeley National Laboratory examines the potential impacts of customer-sited solar photovoltaics on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility and may be reduced through a variety of regulatory and ratemaking measures.
using an aberration-corrected scanning transmission electron microscope, researchers have recently understood how defects in 2-D crystals such as tungsten disulphide can move, or dislocate, to other locations in the material. Understanding how atoms "glide" and "climb" on the surface of 2-D crystals may pave the way for researchers to develop materials with unusual or unique characteristics.
The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports produced by Lawrence Berkeley National Laboratory (Berkeley Lab). A third Berkeley Lab report, written in collaboration with researchers at Yale Univ., the Univ. of Texas at Austin and the DOE, shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic prices.
A team of Lawrence Berkeley National Laboratory researchers believes it has uncovered the secret behind the unusual optoelectronic properties of single atomic layers of transition metal dichalcogenide (TMDC) materials, the 2-D semiconductors that hold great promise for nanoelectronic and photonic applications.
