Flexible, stretchable fire-ant rafts

What do Jell-O, toothpaste, and floating fire-ant rafts have in common? All are so-called "viscoelastic" materials, meaning that they can both resist flow under stress, like honey, and they can bounce back to their original ...

Better combustion through plasma

Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion ...

NREL test helps make moisture barriers better

Moisture—in the form of humidity, water spills, or rainfall—spells early demise for cell phones, light-emitting diode (LED) displays, TVs, and solar photovoltaic (PV) panels worldwide.

Proton radius puzzle may be solved by quantum gravity

(Phys.org) —Officially, the radius of a proton is 0.88 ± 0.01 femtometers (fm, or 10-15 m). Researchers attained that value using two methods: first, by measuring the proton's energy levels using hydrogen spectroscopy, ...
