Laser scanning may help prevent urban trees from falling

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A team from the University of São Paulo has developed an algorithm for optimal pruning that makes trees less vulnerable to wind tunnels. The goal is to create an app to guide human work.

Twisting graphene into correlation and topology

Science China Press
Peer-Reviewed Publication

The discovery of twisted graphene moiré superlattices has opened new avenues for exploring low-dimensional quantum states of matter. This review summarizes recent experimental and theoretical advances in twisted graphene systems, focusing on electron correlation, unconventional superconductivity, and topological states emerging from moiré flatbands, while highlighting their underlying mechanisms, characterization techniques, key open questions and future research directions.

Noisy bubbles hinder ultrasound-boosted chemical reactions: Sonochemistry model shows

Osaka Metropolitan University
Peer-Reviewed Publication

Osaka Metropolitan University researchers have developed a new model that can explain why increasing ultrasound past a certain point hinders chemical reactions rather than continuing to boost them. Their simulations revealed that the interactions between ultrasound waves and cavitation bubbles create sounds that distort the acoustic field and reduce reaction efficiency.

HKU Chair Professor Xuhua He elected vice president of the International Mathematical Union

The University of Hong Kong
Grant and Award Announcement

Professor Xuhua He, Chair Professor in the Department of Mathematics under the Faculty of Science at The University of Hong Kong (HKU), has been elected Vice President of the International Mathematical Union (IMU). At 47, Professor He is the youngest Vice-President to join the Union’s leadership in nearly two decades, and only the second Chinese mathematician to hold this prestigious position since the IMU’s inception. The appointment was formally announced on 21 July at the IMU General Assembly in New York, USA.

WVU study explores AI’s role in training tomorrow’s psychiatrists

West Virginia University
Peer-Reviewed Publication

As the use of artificial intelligence for mental health conditions grows for both patients seeking support and psychiatrists treating them, West Virginia University researchers put ChatGPT-5 Pro to the test to determine its abilities on the psychiatry educational front. Their research showed human supervision is still a top priority when it comes to ensuring patient safety and ethical use of the tool for medical training.

Microplastics can reduce cadmium toxicity in plants, but the protective effect depends on environmental conditions

Shenyang Agricultural University Collaborative Journals
Peer-Reviewed Publication

Cadmium contamination threatens agricultural productivity and food safety worldwide. At the same time, microplastics are becoming increasingly common in farmland soils. A new global meta-analysis shows that when these two pollutants occur together, microplastics can sometimes reduce the harmful effects of cadmium on plants by limiting its uptake and movement through plant tissues.

Autonomous oxygen titration for maintaining normoxemia in acutely ill adults

JAMA Network
Peer-Reviewed Publication

About the Study: Can autonomous oxygen titration increase the proportion of time acutely ill adults receiving supplemental oxygen spend in a targeted normoxemia range (peripheral oxygen saturation 90%-96%) and decrease time spent in hypoxemia (peripheral oxygen saturation <88%)? In this randomized clinical trial among 300 acutely ill adults in 4 US hospitals, autonomous oxygen titration increased the proportion of time spent in normoxemia and decreased the proportion of time spent in hypoxemia compared to usual care. Autonomous oxygen titration safely increased the time that acutely ill adults spent in a targeted normoxemia range compared with oxygen delivery in current clinical care.
