HKUST-led research unveils early predictors of glioma evolution by CELLO2, a self-constructed machine-learning model

A research team led by HKUST developed an AI-powered model to predict glioma patients' prognosis and identify early predictors of tumor evolution under therapy. The model, CELLO2, uses genomic and transcriptomic data from 544 glioma patients to accurately predict treatment-induced hypermutation and grade progression.

Genes may be responsible for third of complex regional pain syndrome cases

Researchers found that genetic variations in four genes were more common in people with CRPS than those with chronic back pain. However, men were more likely to have these genetic variants but less likely to develop the condition. This suggests that sex-specific mechanisms may be at play, which could influence treatment responses.

Illinois researchers prove that new method can be used to measure ozone stress in soybeans

A team from the University of Illinois used solar-induced chlorophyll fluorescence (SIF) to measure the effects of elevated ozone on soybean plants, finding a 36% decrease in SIF during the late growing season. The study confirms that decreased SIF is a sign of stress and provides a non-invasive way to study photosynthesis.
