It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. They found that aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles by about 10 to 40 percent in stop-and-go traffic and roughly 15 to 30 percent at highway speeds. This can equate to losing about $0.25 to $1 per gallon.

COHERENT collaborators were the first to observe coherent elastic neutrino–nucleus scattering. Their results, published in the journal Science, confirm a prediction of the Standard Model and establish constraints on alternative theoretical models. Image c

After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

Using neutron scattering at Oak Ridge National Laboratory, a research team captured a time-sensitive phenomenon to prove that the entropy, or randomness, of atoms in a metallic glass when exposed to intense heat is linked to how atoms self-configure versus their vibration. The large neutron flux of ORNL’s Wide Angular Range Chopper Spectrometer continuously recorded changes in the sample’s vibrations as the temperature slowly increased—a technique not possible a decade ago.
