Published How quantum light 'sees' quantum sound



Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.
Published New methods for effective transport of large genes in gene therapy



One problem in gene therapy is that not all genes transfer equally well into the target cells. Researchers have now developed a flexible method to transfer large genes efficiently and without significant side effects. The approach has strong potential for therapeutic use.
Published Cathode active materials for lithium-ion batteries could be produced at low temperatures



Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes.
Published Unexpected behavior discovered in active particles



Physicists have now shown that, depending on the extent to which the propulsion speed of active particles is dependent on their orientation, clusters in different shapes arise in many-particle systems. This might be a possible key to the realization of programmable matter.
Published Mimics human tissue, fights bacteria: New biomaterial hits the sweet spot



A new lab-made substance mimics human tissue and could reduce or replace the use of animal-derived materials in biomedical research.
Published Chemists, engineers craft adjustable arrays of microscopic lenses



A team has created minuscule lenses that it can expand or contract in mere seconds -- modifying their magnification, focal length and other optical properties in the process. That on-the-fly adaptability bodes well for the design's use in micro-projection systems and even the culturing of cells, the researchers said.
Published Researchers develop DANGER analysis tool for the safer design of gene editing



A team of researchers has developed a software tool that provides a way for the safer design of genome editing in all organisms with a transcriptome. For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR. The new analysis system overcomes these challenges and allows researchers to perform safer on- and off-target assessments without a reference genome. It holds the potential for applications in medicine, agriculture, and biological research.
Published International team develops novel DNA nano engine



An international team of scientists has recently developed a novel type of nano engine made of DNA. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex nano machines.
Published Physical theory improves protein folding prediction



Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.
Published NUS scientists develop innovative magnetic gel that heals diabetic wounds three times faster



A team of researchers has engineered an innovative magnetic wound-healing gel that promises to heal diabetic wounds three times faster, reduce the rates of recurrence, and in turn, lower the incidents of limb amputations. The innovative magnetic hydrogel, which contains skin cells for healing as well as magnetic particles, takes a comprehensive 'all-in-one' approach to wound healing, accelerating the process on several fronts. To maximize therapeutic results, a wireless external magnetic device is used to activate skin cells and accelerate the wound healing process.
Published A miniature magnetic resonance imager made of diamond



The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.
Published Cobalt-free battery for cleaner, greener power



High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.
Published Soft optical fibers block pain while moving and stretching with the body



New soft, implantable fibers can deliver light to major nerves through the body. They are an experimental tool for scientists to explore the causes and potential treatments for peripheral nerve disorders in animal models.
Published Going rogue: Scientists apply giant wave mechanics on a nanometric scale



Researchers have shown how the principles of rogue waves -- huge 30-meter waves that arise unexpectedly in the ocean -- can be applied on a nano scale, with dozens of applications from medicine to manufacturing.
Published Using computer algorithms to find molecular adaptations to improve COVID-19 drugs



A new study focuses on using computer algorithms to generate adaptations to molecules in compounds for existing and potential medications that can improve those molecules' ability to bind to the main protease, a protein-based enzyme that breaks down complex proteins, in SARS-CoV-2, the virus that causes COVID-19.
Published Nanoparticle vaccine could curb cancer metastasis to lungs by targeting a protein



Engineers have developed an experimental vaccine that could prevent the spread of metastatic cancers to the lungs. Its success lies in targeting a protein known to play a central role in cancer growth and spread, rather than targeting the primary tumor itself.
Published Simplifying the generation of three-dimensional holographic displays



Holograms have long held the promise of offering immersive three-dimensional (3D) experiences, but the challenges involved in generating them have limited their widespread use. Capitalizing on the recent developments in deep learning, researchers now propose a game-changing approach that utilizes neural networks to transform ordinary two-dimensional color images into 3D holograms. The proposed approach can simplify 3D hologram generation and can find applications in numerous fields, including healthcare and entertainment.
Published As surging threats teeter electrical power grids, scientists offer insights to make them more resilient



Power grids -- the web of electrical networks that sprawl across countries and continents -- are under stress. Extreme weather events and volatile energy demands often push the system to the brink. Although these high-impact events can be very damaging, often overlooked is the impact of minor disruptions that trigger a domino effect throughout the system, according to a study analyzing European power blackouts. The findings showed that recovering power within 13 hours can reduce up to 52% of the power loss stemming from cascading events.

When stacked in five layers in a rhombohedral pattern, graphene takes on a rare 'multiferroic' state, exhibiting both unconventional magnetism and an exotic electronic behavior known as ferro-valleytricity.
Published Researchers test seafloor fiber optic cable as an earthquake early warning system



One of the biggest challenges for earthquake early warning systems (EEW) is the lack of seismic stations located offshore of heavily populated coastlines, where some of the world's most seismically active regions are located. In a new study, researchers show how unused telecommunications fiber optic cable can be transformed for offshore EEW.
