Spin waves observed directly at nanoscale for first time
For the first time, spin waves, also known as magnons, have been directly observed at the nanoscale. This breakthrough was made possible by combining a high–energy-resolution electron microscope with a theoretical method developed at Uppsala University. The results open exciting new opportunities for studying and controlling magnetism at the nanoscale.
Cost Effective way of Converting Hemp Waste into Ethanol Fuel
Breaking the cellulose and hemicellulose chain has for a long time been a very expensive process. Now with research and this new system it can be done in a rather simple and cost effective manner.
For long, the most expensive part of making cellulosic ethanol has been to be able to break this molecule chain, making it non-competitive with corn ethanol. With this new technology, cellulosic ethanol can compete with corn ethanol as cellulosic ethanol is more environmentally friendly alternative.
To learn more about the basics of cellulosic ethanol and starch ethanol, see the article linked below.
This is the latest and greatest innovation in the world of cellulosic ethanol production. It shows potential for significant cost savings and proving to be even more profitable than corn ethanol.

New scheme mitigates self-discharging in quantum batteries
Quantum batteries (QBs) are energy storage devices that could serve as an alternative to classical batteries, potentially charging faster and enabling the extraction of more energy. In contrast with existing batteries, these batteries leverage effects rooted in quantum mechanics, such as entanglement and superposition.
Despite their promise, QBs have not yet reached optimal performances, partly because they are prone to decoherence simultaneously. This is a loss of coherence (i.e., the ability of quantum systems to exist in a superposition of multiple states), prompted by interactions between a system and its surrounding environment.
Decoherence causes QBs to self-discharge, or in other words, to spontaneously start releasing the energy they are storing. This self-discharging process has so far prevented the batteries’ practical application.
Trestle Bio Announces Research Collaboration with Humacyte
Researchers have created a cement-based material that does more than just provide structural support—it can generate and store electricity. This breakthrough could mark a turning point for future infrastructure in smart cities.
The material is a cement-hydrogel composite developed by a team led by Professor Zhou Yang at Southeast University in China. The team took inspiration from the layered structure inside plant stems to create a material that can harness thermal energy and convert it into electricity.
This is a repost. I think Andrew posted it earlier.
