Phys.org / Statistical method broadens forecasts by modeling uncertainty beyond average outcomes

When it comes to statistics, we usually expect to be informed about what happens "on average." But sometimes the key information lies in deviations from that mean: how likely is heavy rain, and how likely is it to remain ...

Phys.org / Chemists shrink gallium nitride, the material behind LED lighting, into nanocrystals

Nanocrystals are so useful that they formed the basis of the 2023 Nobel Prize in Chemistry. But despite their usefulness, scientists have so far been able to make these microscopic crystals from only a limited palette of ...

Phys.org / Driving the speed limit could slash fuel use and emissions at the cost of only 54 extra seconds a day

Speeding in your car to work, to pick up your children from school, or go from one errand to the next not only wastes money in gas and sends harmful emissions into the air, it barely saves you time, new research says.
