Cemental tear is a rare dental condition where the cementum detaches from tooth roots. Often misdiagnosed, it can lead to unnecessary treatments and tooth loss. An international expert consensus has created guidelines for identifying and treating this overlooked condition, aiming to prevent tooth loss and improve care for similar dental problems. The consensus also addresses critical gaps in knowledge that can lead to ineffective treatments and avoidable extractions.

Patients who are critically ill require constant monitoring and care. In such patients, creating a safe vein access is essential for continuous administration of medication and for monitoring the blood parameters. A novel ultrasound technique for inserting catheters into major veins near the collarbone demonstrated a 100% success rate and avoided serious complications like pneumothorax in critically ill adults, according to a retrospective study published in the Journal of Intensive Medicine.

In this study, an integrated artificial intelligence (AI)-atomic force microscopy (AFM) platform is introduced that enables label-free, mechanophenotyping of macrophages at single-cell resolution.

Antibiotic residues in farmland soils are an emerging global concern, with potential risks for ecosystems, food safety, and human health. Now, researchers in China report a promising new approach to tackling one of the most common culprits—oxytetracycline (OTC)—by combining biochar with carbohydrate-based soil amendments. Their study shows that this simple yet effective strategy not only accelerates the degradation of OTC in soil but also reduces its transfer into lettuce, a widely consumed leafy vegetable.

In a comprehensive meta-analysis that delves into the environmental benefits of biochar, researchers are exploring its impact on reducing N2O emissions from fertilized cropland soils. The study, titled "Biochar Reduces N2O Emission from Fertilized Cropland Soils: A Meta-Analysis," is led by Prof. Xingliang Xu from the Key Laboratory of Ecosystem Network Observation and Modeling at the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences in Beijing, China, and the College of Resources and Environment at the University of Chinese Academy of Sciences in Huairou District, Beijing, China. This research provides a detailed examination of how biochar can mitigate greenhouse gas emissions in agricultural settings.

Ever wondered how we can clean wastewater more efficiently? Scientists have discovered that biofilters made from pyrite and sawdust can remove harmful nitrogen compounds through a fascinating mix of bacteria and chemical reactions. Learn how these simple materials could transform wastewater treatment!

Discover how machine learning is helping researchers identify different groups of chronic obstructive pulmonary disease (COPD) patients in China and understand how their health conditions impact daily life. This new study offers insights into targeted treatments and better quality of life for those living with COPD.

In this study, we propose a high quality-factor (Q-factor) optical cavity that offers a breakthrough solution to the intrinsic trade-off between optical chirality density and mode loss.
