Efforts to engineer new metabolic pathways into microbes for the inexpensive production of valuable chemical products, such as biofuels or therapeutic drugs, should get a significant boost in a new development from the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI). Researchers there have successfully demonstrated a technique they call "targeted proteomics" that speeds up and improves the ability to identify and quantify specific proteins within a cell or microorganism....

Berkeley Lab Scientists Discover Dynamic Double-Strand Break Repair in Heterochromatin DNA is under constant attack, from internal factors like free radicals and external ones like ionizing radiation. About 10 double-strand breaks "“ the kind that snap both backbones of the double helix "“ occur every time a human cell divides. To prevent not only gene mutations but broken chromosomes and chromosomal abnormalities known to cause cancer, infertility, and other diseases in humans,...

A Berkeley Lab-led team deciphers the structure of FEN1, a key player in DNA replication and repair DNA replication is critical to the life of all organisms, insuring that each new cell, as well as each new offspring, gets an accurate copy of the genome. Among the legions of proteins that do the work so essential to a cell's survival, the DNA-slicing "flap endonuclease" FEN1 plays a key role. The structure of human FEN1 has now been solved by an international team of scientists led by the...

Superlenses earned their superlative by being able to capture the "evanescent" light waves that blossom close to an illuminated surface and never travel far enough to be "seen" by a conventional lens. Superlenses hold enormous potential in a range of applications, depending upon the form of light they capture, but their use has been limited because most have been made from elaborate artificial constructs known as metamaterials. The unique optical properties of metamaterials, which include the...

Berkeley Lab scientists accelerate calculations a million times As conventional accelerators like CERN's Large Hadron Collider grow ever more vast and expensive, the best hope for the high-energy machines of the future may lie in "tabletop" accelerators like BELLA (the Berkeley Lab Laser Accelerator), now being built by the LOASIS program at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). BELLA, a laser-plasma wakefield accelerator, is remarkably compact....

Carbon Capture and Storage: Carbon Dioxide Pressure Dissipates in Underground Reservoirs, Study Shows The debate surrounding carbon capture and storage intensifies as scientists from the Earth Sciences Division at the Lawrence Berkeley National Laboratory (Berkeley Lab) examine the capacity for storing carbon dioxide underground, in a study published today in the new journal Greenhouse Gases: Science & Technology. The study debates some of the conclusions drawn in an earlier study by...

"The nation that controls magnetism will control the universe," famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there's little doubt the nation that leads the development of advanced magnetoelectronic or "spintronic" devices is going to have a serious leg-up on its Information Age competition. A smaller, faster and cheaper way to store and transfer information is the spintronic grand prize and a key to winning this prize is understanding and...

Systems biology is a holistic approach to the study of how a living organism emerges from the interactions of the individual elements that make up its constituent cells. Embracing a broad range of disciplines, this field of science that is just beginning to come into public prominence holds promise for advances in a number of important areas, including safer, more effective pharmaceuticals, improved environmental remediation, and clean, green, sustainable energy. However, the most profound...

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have learned to control the quantum pathways determining how light scatters in graphene. Controlled scattering provides a new tool for the study of this unique material "“ graphene is a single sheet of carbon just one atom thick "“ and may point to practical applications for controlling light and electronic states in graphene nanodevices....

Since the 1970s, hydrogen has been touted as a promising alternative to fossil fuels due to its clean combustion "”unlike hydrocarbon-based fuels, which spew greenhouse gases and harmful pollutants, hydrogen's only combustion by-product is water. Compared to gasoline, hydrogen is lightweight, can provide a higher energy density and is readily available. But there's a reason we're not already living in a hydrogen economy: to replace gasoline as a fuel, hydrogen must be safely and densely...
