- Your brain starts making social decisions before you do
Researchers discovered that social behavior begins in the brain before visible movement occurs. In zebrafish, a coordinated brain activity pattern preceded approaching another fish, with the pallium region playing a key role and stronger neural signals correlating with increased social behavior.
- Daily briefing: Gene-activity ‘clock’ predicts biological ageing
A new gene-activity 'clock' tool predicts biological ageing in rodents and monkeys, and human time to death. The article also notes zebrafish sleep in stages similar to humans and highlights efforts to intercept lung cancer before it starts.
- Scientists found the “holy grail” gene that could one day help humans regrow limbs
Scientists have discovered a set of genes that could help humans regrow lost limbs by studying axolotls, zebrafish, and mice. The researchers identified powerful SP genes involved in regeneration and used gene therapy to partially restore regeneration in mice. This breakthrough marks a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics.
