New way to reduce plant lignin could lead to cheaper biofuels
Berkeley Lab scientists have shown for the first time that an enzyme can be tweaked to reduce lignin in plants. Their technique could help lower the cost of converting biomass into carbon-neutral fuels to power your car and other sustainably developed bio-products.

A new recipe for biofuel: Genetic diversity can lead to more productive growth
A team of national laboratory and university researchers led by the Department of Energy's Argonne National Laboratory is growing large test plots of switchgrass crops with the farmer in mind. For the first time, researchers have mixed different genetic varieties of switchgrass on production-size plots, hypothesizing this could increase yield by extending the growing season, varying the size of the switchgrass plants to produce a fuller crop and potentially reducing the crop's vulnerability to weather fluctuations.

PPPL researchers advance understanding of turbulence that drains heat from fusion reactors
Physicists at the US Department of Energy's Princeton Plasma Physics Laboratory appear to have gained important new insights into what affects plasma turbulence, which can impact the leakage of heat from the fusion plasma within tokamaks. Understanding how fusion plasmas lose heat is crucial because the more a plasma is able to retain its heat the more efficient a fusion reactor can be.

Titan probes depths of biofuel's biggest barrier
Cellulosic ethanol -- fuel derived from woody plants and waste biomass -- has the potential to become an affordable, renewable transportation fuel that rivals gasoline, but lignin, one of the most ubiquitous components of the plant cell wall, gets in the way. To better understand exactly how lignin persists, a team based at Oak Ridge National Laboratory created one of the largest biomolecular simulations to date -- a 23.7-million atom system representing pretreated biomass (cellulose and lignin) in the presence of enzymes.

Ice sheet modeling of Greenland, Antarctica helps predict sea-level rise
Predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior. To better understand this loss, a team of Sandia National Laboratories researchers has been improving the reliability and efficiency of computational models that describe ice sheet behavior and dynamics. This research is part of a five-year project called Predicting Ice Sheet and Climate Evolution at Extreme Scales, funded by the US Department of Energy's Scientific Discovery through Advanced Computing program.

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.'

How true is conventional wisdom about price volatility of tech metals?
Preliminary research by the Colorado School of Mines (Mines) and funded by the Critical Materials Institute (CMI) suggests that conventional wisdom about the high price volatility of by-product metals and minerals is generally true, but with several caveats.

SLAC X-ray laser turns crystal imperfections into better images of important biomolecules
Often the most difficult step in taking atomic-resolution images of biological molecules is getting them to form high-quality crystals needed for X-ray studies of their structure. Now researchers have shown they can get sharp images even with imperfect crystals using the world's brightest X-ray source at the Department of Energy's SLAC National Accelerator Laboratory.

Carbon emissions affect thousands of years of climate change
The Earth may suffer irreversible damage that could last tens of thousands of years because of the rate humans are emitting carbon into the atmosphere. In a new study in Nature Climate Change, researchers at Oregon State University, Lawrence Livermore National Laboratory and collaborating institutions found that the longer-term impacts of climate change go well past the 21st century.

Claims for solar cell efficiency put to test at NREL
The sheet of paper taped to the door of Keith Emery's office tells the story. On the paper is a simple fever chart showing the improvements made in increasing the efficiency of two dozen types of solar cells. Some of the lines marking record efficiencies date to the mid-1970s. Others start much more recently, with the advent of newer technologies.

Scientists propose 'pumpjack' mechanism for splitting and copying DNA
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.

Chiral magnetic effect generates quantum current
Scientists at the US Department of Energy's Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-"handed" particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity-the ability of some materials to carry current with no energy loss.
