- T cell therapy trains the immune system to find cancer.
- These treatments help some people but not all patients.
- The therapy depends on a T cell receptor protein.
- Scientists used a special microscope to view the receptor.
- They put the receptor into a small membrane patch.
- The resting receptor stayed closed and folded inside the membrane.
- When it met a target molecule, it opened like a spring.
- Assembling the membrane and proteins was hard for researchers.
- The new view could help improve future immunotherapies.

Engineered bacteria produce tagatose sweetener
Tufts researchers engineered Escherichia coli to make tagatose, a rare sugar that can substitute for table sugar. They used a slime mold enzyme and another enzyme to convert glucose, producing higher yields; tagatose is low‑calorie and FDA‑recognized as safe.
