- Researchers make injectable bandages to stop bleeding.
- The bandage works inside deep wounds and cavities.
- It helps blood form a clot quickly at wounds.
- The dressing changes to a foam in the body.
- The materials are tiny particles from clay-like sources.
- Designers made the particles safer and synthetic.
- A main problem is particles washing away in blood.
- Engineers made two ways to keep particles inside.
- One way expands to fill and seal the wound.
- The other way makes a tight plug to stop flow.

A University of Notre Dame study using national survey data finds that improved access to safe drinking water lowers the odds of stunting in Mozambican children by about 20%. Improved sanitation showed no independent effect on stunting.
New device measures blood viscosity in real time
Researchers at the University of Missouri created a non-invasive device that monitors blood viscosity and density in real time using ultrasound and software. It can read blood without drawing samples and may help in diseases like sickle cell.
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.
