Through drought and flood, winter freeze and summer heat, and the occasional deer nibble or beaver gnaw, trees stand sturdy. Partly, trees can thank genetic makeup, refined through millennia, for the ability to overcome much of what Mother Nature hurls their way.
The early 1980s conventional wisdom was that almost everything was known about ribosomes, the cellular structures responsible for making proteins according to the genetic instructions.
Inadequate insulation is one of the largest causes of wasted energy, quickly allowing comfortable heating or cooling to disperse air outside.
Scientists at the US Department of Energy’s Oak Ridge National Laboratory are learning how the properties of water molecules on the surface of metal oxides can be used to better control these minerals and use them to make products such as more efficient semiconductors for organic light emitting diodes and solar cells, safer vehicle glass in fog and frost, and more environmentally friendly chemical sensors for industrial applications.
Enzymes are catalysts that speed up chemical reactions in living organisms and control many cellular biological processes by converting a molecule, or substrate, into a product used by the cell. For scientists, understanding details of how enzymes work is essential to the discovery of drugs to cure diseases and treat disorders.
Researchers at the Department of Energy’s Oak Ridge National Laboratory, working collaboratively with scientists funded by The American Chestnut Foundation, have helped confirm that addition of a wheat gene increases the blight resistance of American chestnut trees.
Ethers—simple organic molecules in which an oxygen atom bridges two carbon atoms—are the chemical building blocks of commonplace products including many solvents, propellants, cosmetics and pharmaceuticals. Link them together in large molecular rings and they become scientific royalty—crown ether molecules, whose development led in large part to the 1987 Nobel Prize in chemistry.
If you took a photograph of the Milky Way galaxy today from a distance, the photo would show a spiral galaxy with a bright, central bar (sometimes called a bulge) of dense star populations.
For several years, the Department of Energy’s Oak Ridge National Laboratory has supported the National Guard and Reserve’s Boss Lift Program, which gives employers a chance to visit military installations to see first-hand what reservists do.
When Department of Energy and Oak Ridge National Laboratory researcher Yan Xu talks about “islanding,” or isolating, from the grid, she’s discussing a fundamental benefit of microgrids—small systems powered by renewables and energy storage devices. The benefit is that microgrids can disconnect from larger utility grids and continue to provide power locally.
