- Biomedical engineers at Texas A&M University do this research.
- They use tiny nanoflower particles near stem cells.
- Nanoflowers make stem cells create more mitochondria than usual.
- The stem cells make about twice the normal amount.
- Stem cells then give extra mitochondria to weak cells.
- Damaged or aging cells get new mitochondria and energy.
- Rejuvenated cells restore function and resist cell death.
- Researchers say no genetic changes or drugs are needed.
Difficult words
- mitochondria — a small part in a cell that makes energy

- Rejuvenated — to make something healthy and new again
- Researchers — a person who studies or does scientific work

Yale reveals molecular structure of cholera flagella
Yale researchers imaged the molecular structure of Vibrio cholerae flagella in living bacteria. The study shows how flagella proteins sit inside a hydrophilic sheath and suggests the sheath helps the bacterium move and infect cells.
