Researchers use light-activated nanozymes to treat aggressive brain tumors

Brain tumors cannot always be successfully treated with conventional therapies. A team from Empa and the hospital network HOCH Health Ostschweiz is therefore developing nanozymes that can attack cancer cells directly in the brain during tumor surgery.

New hybrid molecule uses Trojan horse approach to treat obesity

A team led by metabolism researcher Prof Timo D. Müller at Helmholtz Munich has developed a new approach for treating obesity and type 2 diabetes: a hybrid molecule uses the well-known GLP-1/GIP signalling pathway as a "door opener" and delivers an additional metabolic modulator specifically into the target cells.

Maternal antibodies provide lifelong protection against adult gum disease

Mothers provide a hidden immune legacy that protects their children's teeth long after weaning is over. A new study reveals how maternal antibodies act as early life architects, programming the mouth to resist aggressive bacteria and prevent the bone loss associated with adult gum disease.

Scientists redesign CAR-T cells to fight more than cancer

This review examines how CAR-T cell therapy is expanding beyond blood cancers into solid tumors, autoimmune diseases, chronic viral infections, and next-generation immune-cell platforms. It highlights promising engineering advances, including universal CAR-T cells, in vivo delivery, CAR-NK cells, and safety switches, while emphasizing unresolved challenges in durability, safety, scalability, and global access.

Wearable sweat sensor tracks vitamin levels in real time

Researchers developed a wearable electrochemical patch that detects six vitamins in sweat at nanomolar levels, combining sweat induction, microfluidic sampling, wireless readout, and pH/ionic-strength calibration. Human testing focused mainly on vitamin B9, showing sweat levels rose after supplementation or a vitamin B9-rich diet and correlated with serum levels, supporting future use for non-invasive nutrition trend monitoring.

TikTok chatter could help predict where the opioid crisis is heading next

A large-scale analysis of 569,581 TikTok comments found that opioid-related discussions may help track and forecast synthetic opioid overdose mortality in the US. Recovery, harm reduction, drug use, drug sourcing, and loss-related conversations provided near-real-time signals that improved 6-month forecasting accuracy.

Why H2N2 flu is back on the pandemic preparedness radar

A historical review in Vaccine warns that global H2N2 immunity has sharply declined since the 1957 Asian influenza pandemic, leaving most people without H2-specific protection if the virus re-emerges. The authors highlight animal reservoirs, waning birth-cohort immunity, and modern H2 vaccine platforms as key priorities for pandemic preparedness.
