Young scientists who frequently handle laboratory chemicals and consume relatively few antioxidant-rich foods may be more likely to report symptoms such as fatigue, headaches, pallor, and easy bruising, according to a new study of university students in Nigeria.

A research team has revealed how the wheat transcription factor TaPGS1 may increase grain size by enriching flavonols, altering the local distribution of the plant hormone auxin, and delaying endosperm cellularization. 

Journal of Advanced Ceramics (JAC), the peer-reviewed open-access journal published by Tsinghua University Press, is celebrating its 15th anniversary this year with a special series of five invited review articles by distinguished experts in the field. The collection captures the most exciting frontiers in ceramic science and technology, from ultra-high-temperature materials to data-driven discovery.

Despite advances in restoring blood flow after ischemic stroke, many patients continue to experience lasting disability. Now, researchers show that administering rapamycin immediately after recanalization significantly reduces brain damage and improves neurological recovery in a rat model of stroke. These changes occur without increasing blood flow, suggesting that rapamycin protects the brain through alternative mechanisms. The findings highlight the potential of rapamycin as a future adjunct therapy for ischemic stroke. 

Pulmonary arterial hypertension (PAH) is a rare but life-threatening disease that progressively damages the blood vessels of the lungs and can lead to heart failure. A new review published in the Chinese Medical Journal highlights how advances in genetics, immune biology, and metabolism are transforming scientists' understanding of PAH. By bringing together recent discoveries and emerging therapies, the study suggests that targeting the disease's underlying drivers could pave the way for more effective treatments.

Artificial intelligence (AI) is emerging as a promising domain for inflammatory bowel disease (IBD) care across multiple clinical settings. In a review study, researchers highlight how AI may support disease monitoring, dysplasia detection, outcome prediction, treatment selection, and precision medicine, while emphasizing that clinical translation still requires multicenter validation, transparent models, ethical safeguards, and integration with clinician oversight before routine practice is widely adopted.

A retrospective study of 61 patients with wide-necked intracranial aneurysms found that LVIS stent-assisted coiling achieved complete initial occlusion in 80.0% of ruptured and 84.6% of unruptured aneurysms. In 14 patients analyzed with computational fluid dynamics, treatment substantially reduced aneurysm inflow and wall shear stress, with changes sustained at 6 months. Findings suggest potential hemodynamic benefits while highlighting thrombotic risks and the need for larger, prospective, comparative studies to confirm efficacy. 

As entropy returns to the scientific spotlight, an Editorial published in Intelligent Medicine proposes a new frame work arguing that critical illness may reflect a breakdown of physiological coordination, and outlines how multimodal data and interpretable AI could help test the idea.

In a paper published in SCIENCE CHINA Earth Sciences, a team of researchers analyzed tidal data at 362,370 oceanic locations spotted by the Jason-3 satellite, revealing that the distribution of high and low tides directly contradicts the physical existence of two water bulges—a model that has been widely taught in textbooks. This discovery provides evidence for the recently proposed oceanic basin oscillation-driving mechanism of tides.

A study published in National Science Review shows that climate change is reorganizing China’s cropland nitrogen pollution. Although the humid south currently exports more nitrogen, rising rainfall may increase cropland nitrogen export from the arid and semi-arid north by 18.8%–53.2% by 2050. The findings call for source control in the north and stronger aquatic nitrogen removal in the south.
