Malaria Parasites Twist for Survival
4 Dec
Summary
- Malaria parasites move in right-handed helical paths in 3D environments.
- Helical motion helps microbes travel farther in noisy, unpredictable spaces.
- New model suggests helical paths aid efficient movement and direction stability.
Scientists have uncovered that malaria parasites predominantly move in right-handed helical paths within three-dimensional environments. This corkscrew-like motion is not merely a characteristic quirk but a survival strategy that aids efficient travel through complex, noisy spaces.
Recent research utilized a novel mathematical model to simulate this movement, incorporating 'colored noise' which accounts for predictable fluctuations. This approach accurately reflected the observed paths of malaria parasites gliding through synthetic hydrogels, suggesting helical motion offers advantages over straight-line travel.
The findings indicate that this unique locomotion helps microorganisms like the malaria parasite cover more ground effectively, maintaining a more stable overall direction despite inherent environmental and biological noise. This principle may also apply to other microscopic swimmers and inform the design of future medical nanobots.
