How a nearby supernova left its mark on Earth life
When a massive star explodes as a supernova, it does more than release an extraordinary amount of energy. Supernovae explosions are responsible for creating some of the heavy elements, including iron, which is blasted out into space by the explosion......»»
How professional sports leagues that embrace social justice causes could influence politics
Given that 77 percent of people in Canada and 57 percent of people in the United Kingdom watch a sports team regularly—compared to the 60 percent of people who turn out to vote in Canada and the U.K.—it's clear sports have an important and persis.....»»
Manganese cathodes could boost lithium-ion batteries
Rechargeable lithium-ion batteries are growing in adoption, used in devices like smartphones and laptops, electric vehicles, and energy storage systems. But supplies of nickel and cobalt commonly used in the cathodes of these batteries are limited......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
