A research team at the University of Cologne and University Hospital Cologne identifies a circuit in the brain that counteracts anxiety and helps to restore balanced behaviour. The result could contribute to developing treatment options for anorexia nervosa, one of the deadliest mental illnesses / publication in “Nature Neuroscience”

Perovskite materials offer exceptional optoelectronic properties for photodetectors, but precise patterning is critical to optimize their performance. This review surveys five key patterning strategies—template-guided growth, inkjet printing, vapor deposition, seed-induced growth, and photolithography—highlighting their roles in controlling perovskite microstructures. The resulting patterned films enable high-sensitivity photodetectors across zero- to three-dimensional architectures, facilitating breakthroughs in flexible wearables and biomimetic vision systems. These advances pave the way for next-generation imaging, health monitoring, and human-machine interfaces.

A new clinical trials shows that pembrolizumab, a drug that utilizes the body’s immune system to target and eliminate cancer cells, appeared to reduce the risk of distant metastases for an aggressive form of skin cancer when given immediately after surgery, but did not significantly reduce the overall risk of recurrence, which was a co-primary endpoint of the trial. The randomized phase 3 trial called STAMP or EA6174, is the largest clinical study to date evaluating pembrolizumab as adjuvant therapy for Merkel cell carcinoma, an extremely aggressive disease, with fewer than half of patients surviving 5 years after diagnosis.
