- Scientists at a university now study how cells send signals.
- Cells use networks of proteins to sense their environment.
- One important protein called mTOR controls different cell tasks.
- mTOR works as two parts that do different jobs.
- Many drugs stop both parts of mTOR at the same time.
- Stopping one part can make cancer cells more resistant to treatment.
- The new study shows we could block only one part.
- This idea may help scientists design better cancer drugs in future.

Alternative splicing linked to mammal lifespan
A study in Nature Communications compared alternative splicing across 26 mammal species (lifespans 2.2–37 years) and found splicing patterns better predict maximum lifespan than gene activity; the brain shows many lifespan-linked events controlled by RNA-binding proteins.
