Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.

A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.

Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them. In order to investigate this scenario more closely in the laboratory, researchers have now developed a model with human hair follicles embedded in a matrix produced using 3D printing. In the future, this model can be used to test the effectiveness of new drug candidates against corresponding pathogens directly on human follicles.

An international team of scientists has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.

Single-walled carbon nanotubes (SWCNTs) hold promise for biomedicine and nanoelectronics, yet the functionalization with single-stranded DNA (ssDNA) remains a challenge. Researchers using high-affinity ssDNA sequences identified through high-throughput selection. They demonstrated the effectivity and stability of these constructs using molecular dynamics simulations. Machine-learning models were used to accurately predict patterns that govern ssDNA-SWCNT binding affinity. These findings provide valuable insights into the interactions between ssDNA and SWCNTs.

The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).

When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.

Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues -- it also lines and helps protect the lungs, stomach, intestines and eyes. And now, researchers have demonstrated in mice that their tiny, enzyme-powered 'snot bots' can push through the defensive, sticky layer and potentially deliver drugs more efficiently.

Researchers have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers. As the team reports, these findings could pave the way for novel types of data storage and sensors, including even magnetic variants of neural networks.

Biodegradable electronics allow for medical devices -- such as drug delivery systems, pacemakers or neural implants -- to safely degrade into materials that are absorbed by the body after they are no longer needed. But if the water-soluble devices degrade too quickly, they cannot accomplish their purpose. Now, researchers have developed the ability to control the dissolve rate of these biodegradable electronics by experimenting with dissolvable elements, like inorganic fillers and polymers, that encapsulate the device.

Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
