Researchers developed a tiny fiber probe that can measure three key molecules at the same time: glucose, lactate and ethanol. The probe uses mid‑infrared light to detect each molecule by its light absorption. This allows faster, near‑real‑time readings without taking many fluid samples.
Current methods often collect fluid for later lab analysis, which takes time. The new probe is minimally invasive and could be used in hospitals or adapted for personal wellness monitoring. A patent application has been filed for future industry use.

Antibody and EGFR–STAT1 pathway point to new fibrosis treatments
Researchers at Yale found a human antibody that blocks epiregulin and lowers fibrosis markers. They also show EGFR activates STAT1 in fibroblasts, suggesting two treatment paths: block epiregulin or target the EGFR–STAT1 pathway.
