Fundamental mechanics help increase battery storage capacity and lifespan

Batteries are widely used in everyday applications like powering electric vehicles, electronic gadgets and are promising candidates for sustainable energy storage. However, as you've likely noticed with daily charging of batteries, their functionality drops off over time. Eventually, we need to replace these batteries, which is not only expensive but also depletes the rare earth elements used in making them.

Scientists discover quantum mechanical switching in ferritin structures similar to those found in neural tissue

Quantum mechanics generally refers to the wave-like properties of things that are commonly considered to be particles, such as electrons. This article discusses evidence of a quantum mechanical switching function that is performed by strictly biological structures—ferritin protein layers that are found in cells including neural tissue.

Physicist helps confirm a major advance in stellarator performance for fusion energy

Stellarators, twisty magnetic devices that aim to harness on Earth the fusion energy that powers the sun and stars, have long played second fiddle to more widely used doughnut-shaped facilities known as tokamaks. The complex twisted stellarator magnets have been difficult to design and have previously allowed greater leakage of the superhigh heat from fusion reactions.

Cold planets exist throughout the galaxy, even in the galactic bulge

Although thousands of planets have been discovered in the Milky Way, most reside less than a few thousand light years from Earth. Yet our galaxy is more than 100,000 light years across, making it difficult to investigate the galactic distribution of planets. But now, a research team has found a way to overcome this hurdle.

New mathematical solutions to an old problem in astronomy

For millennia, humanity has observed the changing phases of the Moon. The rise and fall of sunlight reflected off the Moon, as it presents its different faces to us, is known as a "phase curve". Measuring phase curves of the Moon and Solar System planets is an ancient branch of astronomy that goes back at least a century. The shapes of these phase curves encode information on the surfaces and atmospheres of these celestial bodies. In modern times, astronomers have measured the phase curves of exoplanets using space telescopes such as Hubble, Spitzer, TESS and CHEOPS. These observations are compared with theoretical predictions. In order to do so, one needs a way of calculating these phase curves. It involves seeking a solution to a difficult mathematical problem concerning the physics of radiation.
