- The Amazon molly is an all-female fish.
- It reproduces by cloning itself and has no males.
- Cloning often causes genetic problems in animals.
- Scientists at a university studied the fish.
- The fish has lived for a very long time.
- Researchers found the fish DNA looked healthy.
- A natural process helps fix bad genes in DNA.
- This process reduces harmful changes and keeps health.
- The finding may help future animal and plant research.

Light controls a calcium-powered protein engine for artificial cells
Researchers adapted a ciliate calcium-pulse strategy to make a protein network that contracts when calcium is released by light. The light-controlled system can repeat cycles, move tiny particles and may help synthetic drug delivery.
Decaying dark matter may explain early giant black holes
Researchers propose that tiny energy from decaying dark matter changed gas chemistry in the first galaxies. This could let some gas clouds collapse directly into massive black holes, helping to explain early observations by the James Webb Space Telescope.
How germinal centers make stronger antibodies
A mouse study tracked thousands of B cells across many germinal centers to see how antibodies improve. Using imaging and Deep Mutational Scanning, researchers found selection across centers produces stronger antibodies and may guide vaccine design.
