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......»»
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.....»»
Cricket study suggests mating filter narrows when males are trying to save energy
A trio of biologists at the University of Minnesota has found that when male crickets need to save energy, they narrow their mating filter, to focus more exclusively on females......»»
Thermal effects in spintronics systematically assessed for first time
Spintronics—devices that use microscopic magnetism in conjunction with electric current—could lead to computing technology as fast as conventional electronics but much more energy efficient. As such devices are developed and studied, an important.....»»
New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency
Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficien.....»»

Ant queens cannibalize their sick offspring and "recycle" them, new study reveals
Instead of nurturing their sick young, ant queens eat their infected offspring at the first sign of illness then "recycle" them into energy to produce new eggs, a new study led by the University of Oxford has shown. The findings have been published i.....»»
Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
Discovering new energy levels in atomic hyperfine structures
Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the development of Fourier transform spectroscopy, and t.....»»
This forgotten Ridley Scott action thriller is better than you remember (and no, it’s not Blade Runner)
From Alien and Blade Runner to 2024's Gladiator II, Ridley Scott has directed some great movies. This 1989 film isn't one of them, but it's still worth a look......»»
65% of websites are unprotected against simple bot attacks
Companies across industries are seeing more bot-driven attacks, both basic and advanced, according to DataDome. An analysis of over 14,000 websites uncovered alarming gaps in protection against cyber fraud, particularly within consumer-centric indust.....»»
Firms that withdrew from Russia following Ukraine invasion earn higher consumer sentiment, finds study
Following Russia's 2022 invasion of Ukraine, many companies with operations in Russia withdrew from or severely curtailed their Russian operations. For example, Dell and McDonald's ceased all operations in Russia after the invasion......»»
