Research roundup: 6 cool science stories we almost missed
Summary
Japanese scientists studied how dolphins swim fast by using computer simulations that showed how their tail movements create large swirling water currents to push them forward. Understanding this process may help design better underwater robots.Key Facts
- Dolphins swim by moving their tails up and down, pushing water backward.
- This motion creates large spinning currents called vortex rings that help propel them.
- Smaller vortices are formed but do not help with moving forward.
- The study used supercomputer simulations to analyze these water movements.
- Researchers want to use this knowledge to improve underwater robot design.
- The research was published in the journal Physical Review Fluids in 2026.
