Since electric vehicles use no gasoline, their drivers pay no gasoline tax. And as more people drive EVs, gas-tax revenue for road repairs is dwindling. So how can California and the rest of the country avoid road-funding ...

Could we one day control the path of lightning?

Lightning dart across the sky in a flash. And even though we can use lightning rods to increase the probability of it striking at a specific location, its exact path remains unpredictable. At a smaller scale, discharges between ...

Unlocking nature's quantum engineering for efficient solar energy

(Phys.org)—Quantum scale photosynthesis in biological systems which inhabit extreme environments could hold key to new designs for solar energy and nanoscale devices. Certain biological systems living in low light environments ...

Mechanism behind capacitor's high-speed energy storage discovered

Researchers at North Carolina State University have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful ...

Graphene sensor rapidly detects opioid metabolites in wastewater

The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that's the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, ...
