Researchers aim to extend battery life in electric vehicles, phones and laptops instead of sending packs to landfills
New research suggests that fleeting quantum forces leave lasting imprints on the brain, subtly influencing thought, intuition, and the choices we make.

A UNLV professor is looking to an unlikely source to extend the life of the lithium-ion batteries that have become a part of everyday life: X-rays.

Many people shy away from tackling the deep questions everyone has. Questions like “Why are we here?” “Where are we going?” and “What is the meaning of life?” UNLV Professor Dr. Michael Pravica is not one of those people. In fact, he’s spent much of his academic life attempting to answer those very questions with his background as a physicist providing a rational underpinning for his beliefs.
Stuck lithium ions, responsible for older batteries' loss in capacity, could be freed if gently encouraged by high-energy X-rays.
New UNLV-led research may prove the contrary, adding years to the lifespan of our beloved battery-powered electronic devices.
Awareness itself may predate our universe.
Imagine homing in on the source of your consciousness like an airport metal detector finds the keys stashed in your pocket.
Have you found that allergies worsen during extreme weather? It can be due to thunderstorm asthma, also known as thunder fever, when a thunderstorm puts huge amounts of pollen into the air. What causes thunderstorm pollen strikes, and what should homeowners do to stay safe?
