'Fabric' could one day be integrated into clothes or wearable electronics to power devices on the go
Researchers have created a new type of fiber that can perform like a muscle actuator, in many ways better than other options that exist today. And, most importantly, these muscle-like fibers are simple to make and recycle.
Scientists have created a 'time-crystal' a two-body system in an experiment that seems to bend the laws of physics. A 'two-level system' is a basic building block of a quantum computer. Time crystals could perhaps be used to build quantum devices that work at room temperature. Time crystals were long believed to be impossible because they are made from atoms in never-ending motion. The discovery shows that not only can time crystals be created, but they have potential to be turned into useful devices.
Researchers have identified an alternative to lithium-based battery technology by developing sodium glassy electrodes capable of supporting long-duration, grid-scale energy storage.
New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today -- the Hubble constant problem. The Hubble constant is the rate of expansion of the universe today. Predictions for this rate are significantly slower than the rate found by our most precise local measurements. This discrepancy is one that many cosmologists have been trying to solve by changing our current cosmological model.
A team of astrophysicists has arrived at a major result regarding star populations beyond the Milky Way. The result could change our understanding of a wide range of astronomical phenomena, including the formation of black holes, supernovae and why galaxies die.
An international team of astronomers used a database combining observations from the best telescopes in the world, including the Subaru Telescope, to detect the signal from the active supermassive black holes of dying galaxies in the early Universe. The appearance of these active supermassive black holes correlates with changes in the host galaxy, suggesting that a black hole could have far reaching effects on the evolution of its host galaxy.
Electronic devices generate heat, and that heat must be dissipated. The high temperatures can compromise device function or even damage the devices and surroundings if it isn't. Now, a team has detailed a new cooling method that offers a host of benefits, not the least of which is space efficiency which offers a substantial increase over conventional approaches in devices' power per unit volume.
I was an early adopter of the current generation of solar technology when I put panels on our San Jose house in the early 2000s, only to watch the yield from those panels drop sharply over the following 20 years. On our latest home, we use current-generation LG panels which promise to hold over 90% of their generating capacity for that same time.
