Copper amine oxidases, a class of enzymes, play a vital role in the healing process of wounds and detoxification of harmful substances in the human body. Understanding the atomic structure of these enzymes is crucial for enhancing their functionality. However, conventional imaging techniques struggle to accurately depict the positions of hydrogen atoms within these enzymes.

As the world of technology continues to advance at a rapid pace, innovative electronic devices such as foldable displays, wearables, e-skin, and medical devices have emerged. These devices rely heavily on flexible electronic technology, which in turn has created a growing demand for flexible adhesives that can effectively connect various components while maintaining their shape.

Spent coffee grounds (SCG) pose a significant environmental challenge, with almost 6 million metric tons of waste generated globally each year. Recognizing the need for sustainable waste management, researchers are exploring innovative ways to repurpose SCG into value-added products. Led by Associate Professor Liu Shao Quan from the NUS Department of Food Science and Technology,

Researchers from the University of Edinburgh and the University of Cantabria have collaborated to develop an artificial intelligence (AI) model capable of identifying senolytic medicinal chemistry in familiar compounds. The scientists have published a paper titled “Discovery of senolytics using machine learning” in Nature Communications, detailing their efforts to search through over 4,300 scientifically described

Scientists from the University of Tokyo led a team of researchers who have created a new method of imaging and analyzing biological samples. The new imaging method, called RESORT, combines the benefits of two leading technologies: super-resolution fluorescence imaging and vibrational imaging. While super-resolution fluorescence imaging provides good spatial resolution, vibrational imaging compromises spatial resolution

Researchers at the University of Wisconsin-Madison have discovered a new way to speed up the process of discovering new high-performance polymers. By using machine learning and molecular dynamics simulations, they have discovered several promising polyimides out of a field of 8 million candidates. Polyimides are commonly used in the aerospace, automobile and electronics industries for

A team of Chinese scientists from the University of Science and Technology of China (USTC) has developed a new catalyst for hydrogen evolution reaction (HER). The researchers have created a general strategy for the synthesis of ten single-atom doped CoSe2-DETA (DETA = diethylenetriamine) nanobelts. The team has optimized the hydrogen evolution reaction (HER) activity of

Researchers from TUD Dresden University of Technology have discovered an innovative synthesis method for the production of phosphorus-containing chemicals. The new method has been published in the scientific journal, Nature Synthesis. The research team, led by Professor Jan J. Weigand, has developed a sustainable process that requires only two process steps, resulting in significant time

Chemistry faces big challenges in controlling chemical reactions to create new products. This development has a significant impact on the industry, as it reduces waste in the manufacture of construction materials and improves the production of catalysts for speeding up chemical reactions. Polariton chemistry, which uses the tools of chemistry and quantum optics, has seen

Researchers at Eindhoven University of Technology have developed a new catalyst that can convert toxic carbon monoxide into carbon dioxide gas even at room temperature. The so-called three-way catalytic converter in a car’s exhaust system only works correctly when the exhaust gases are several hundred degrees Celsius. As a result, toxic carbon monoxide remains in

Scientists are becoming creative in engineering yeast or bacteria to produce chemicals that are useful. A group of chemists from different universities has a more ambitious goal of retooling the cell’s polypeptide manufacturing plants and modifying the ribosomes that spin amino acids into protein to produce polymer chains that are more elaborate. The goal of

Class I major histocompatibility complex (MHC-I) proteins are crucial in the immune system of all jawed vertebrates. They showcase peptide fragments of proteins present inside the cell on the cell surface, displaying them to the immune system. This allows the immune system to scan the body for foreign or toxic antigens. When foreign peptides are

A group of counterfeiters was recently caught producing fake luxury jewelry items by pouring molten metal into molds produced from the original jewelry. In a similar way, a template scaffold can produce an endless amount of molecular crystals of any shape or form. Researchers at Pohang University of Science and Technology (POSTECH) have used this

A new study conducted by researchers at Stanford University, the National Institute of Standards and Technology (NIST), the University of Maryland, and Colorado State University has found a previously unknown reason why foods cooked at high temperatures, such as red meat and deep-fried foods, elevate the risk of cancer. The research discovered that the DNA
