A new ultrasonic needle for tumour diagnostics has been trialled in collaboration with Aalto University and Helsinki University Hospital (HUS). The needle allows for 2-3x more tissue to be sampled, less invasively, indicating strong potential for significantly higher accuracy in diagnostics.

Invariant natural killer T (iNKT) cells are promising for cancer immunotherapy because they can coordinate broader immune responses, but sourcing enough functional cells is challenging. In a recent study, researchers from Japan showed that combining stem cell-derived iNKT cells with an immune-activating lipid compound can strongly suppress tumors in mice by training the body’s own T cells to recognize and remember cancer. These findings point to a more effective and scalable form of immunotherapy.

Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes, according to a study led by researchers at the University of Gothenburg.

Environmental health experts at Flinders University have found open windows and ventilation can reduce but not completely remove methamphetamine contamination on most hard surfaces of a car after an extended period. 

In a new study, researchers tested various parts of a car’s interior to show concentrations in the air and surfaces exposed to controlled release of methamphetamine smoke. While levels generally dropped over time, the experts warn indirect exposure could still occur, in particular in textile or soft surfaces.

High concentrations of free fatty acid (FFA) in ketotic dairy cows activate endoplasmic reticulum (ER) stress pathways, contributing to mammary epithelial cell apoptosis and reduced milk yield. The study sets the stage for in vivo trials to validate ER stress inhibitors like Tauroursodeoxycholate (TUDCA) as practical solutions for managing ketosis and enhancing dairy cows health.

A research team from Department of Pharmacology and Pharmacy at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), in collaboration with the InnoHK Advanced Biomedical Instrumentation Centre (ABIC), has developed the world’s first ‘NanoPowder nasal spray’. This innovation successfully overcomes the challenge of crossing the blood-brain barrier (BBB), enabling the delivery of medication to the brain without the need for injections or surgery. When used promptly at the early onset of stroke, the nasal spray provides prehospital emergency treatment, helping to save time, thus protecting brain cells and reducing complications. In the long term, it has the potential to become a community-based emergency rescue tool.
