In a paper published in National Science Review, a research team from Peking University presents new insights into magnetic field sensing. The study investigates the limits of quantum magnetometers and explores criteria for determining whether a magnetometer is essentially quantum.
Colorectal cancer (CRC) is a globally prevalent malignancy with high morbidity and mortality rates, closely linked to aberrant epigenetic modifications. Among these, pseudouridine (Ψ), one of the most abundant RNA chemical modifications, plays a pivotal role in tumorigenesis by regulating mRNA stability, translation efficiency, and splicing processes. Recent studies have demonstrated that the small-molecule inhibitor Pyrazofurin, targeting the pseudouridine synthase DKC1, exhibits significant anti-tumor activity, suggesting Ψ modification as a promising therapeutic strategy for CRC. However, the dynamic changes and clinical implications of transcriptome-wide Ψ modifications in CRC remain poorly understood.
Researchers at Nankai University achieved a significant breakthrough in lithium metal batteries (LMBs) by developing a novel in-situ fabricated gel polymer electrolyte (GPE) with a localized high-concentration solvation structure (LHCE-GPE). This innovative LHCE-GPE enables practical solid-state 18650 cylindrical LMBs to operate at a high cutoff voltage of 4.7 V. Furthermore, the unique solvation structure of LHCE-GPE within a polymer matrix ensures excellent electrochemical performance across a wide temperature range (−15~60°C) and provides robust safety during rigorous mechanical abuse tests.
In a recent study, an international team of physicists, led by Prof. JO Gyu-Boong from the Department of Physics at the Hong Kong University of Science and Technology (HKUST) has made a significant observation of the BKT phase transition in a 2D dipolar gas of ultracold atoms. This groundbreaking work marks a major milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions.
Kyoto, Japan -- From the Japanese cypress to the ponderosa pine, wood has been used in construction for millennia. Though materials like steel and concrete have largely taken over large building construction, wood is making a comeback, increasingly being used in public and multi-story buildings for its environmental benefits.
Of course, wood has often been passed over in favor of other materials because it is easily damaged by sunlight and moisture when used outdoors. Wood coatings have been designed to protect wood surfaces for this reason, but coating damage often starts before it becomes visible. Once the deterioration can be seen with the naked eye, it is already too late.
To solve this problem, a team of researchers at Kyoto University is working to create a simple but effective method of diagnosing this nearly invisible deterioration before the damage becomes irreparable.
Scientists found Escherichia albertii, an emerging foodborne pathogen, in 64% of retail chicken meat in Bangladesh. The study revealed widespread contamination, cross-contamination during processing and high antimicrobial resistance. The findings highlight urgent public health risks and the need for improved hygiene, antibiotic regulations and global monitoring.
Roswell Park Comprehensive Cancer Center is at the forefront of a new approach to cancer treatment, called CAR T-cell therapy. The little known, but highly promising technology breakthrough makes it possible for your body to fight cancer, often without invasive surgery, offering patients new hope for the possibility of long-term remission.
However, a new survey by Roswell Park Comprehensive Cancer Center of 1,021 adults in the United States shows 65% are unfamiliar with the personalized cancer treatment option.
