Bees' movements may lead to new swimming, flying robots（图）
Bees movements new swimming flying robots
2020/1/21
Walking on Caltech's campus, engineer Chris Roh happened to see a bee stuck in the water of Millikan Pond. Although it was a common sight, it led Roh and his colleague Mory Gharib to a discovery about...
Tiny swimming 'doughnuts' deliver the biomedical goods（图）
Tiny swimming doughnut biomedical good

Bacteria and other swimming microorganisms evolved to thrive in challenging environments. But it's difficult to harness these microorganisms' abilities for biomedical purposes, so NSF-funded researche...
Rapid Subsurface Ocean Warming in the Bay of Fundy as Measured by Free-Swimming Basking Sharks
Measured Free-Swimming Basking Sharks
2015/7/17
It is widely recognized that the western North Atlantic has recently warmed very rapidly. Sea surface temperatures (SST) in 2012 were measured to be 1–3°C higher than the 1982–2011 average (Mills et a...
Dispersion of swimming algae in laminar and turbulent channel flows: theory and simulations
algae swimming microorganisms Taylor dispersion DNS turbulent transport bioreactors
2012/5/31
Algal swimming is often biased by environmental cues, e.g. gravitational and viscous torques drive cells towards downwelling fluid (gyrotaxis). In view of biotechnological applications, it is importan...
Biased swimming cells do not disperse in pipes as tracers: a population model based on microscale behaviour
Algae dispersion swimming pipe
2012/5/17
There is much current interest in modelling suspensions of algae and other micro-organisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispe...
The effect of lordosis severity on juvenile sea bass (Dicentrarchus labrax L., 1758) swimming performance
Lordosis severity swimming performance Ucrit sea bass
2010/3/25
The relationship between the lordosis severity and swimming performance in sea bass juveniles was investigated. In total, 149 experimental animals 110-130 days old that ranged from 1.44 to 3.44 g (mea...
Orientation and swimming mechanics by the scyphomedusa Aurelia sp. in shear flow
Orientation swimming mechanics
2014/5/4
Individual Aurelia sp. medusae were distributed around regions of current shear associated with vertical density discontinuities during three vertically towed camera profiles in the northern Gulf of M...
The morphology of branching corals effectively blocks impinging currents. Weak flows in the colony’s inner
sections can hinder some of the corals’ basic physiological functions. At night, high ...
Quantification of marine snow fragmentation by swimming euphausiids
marine snow fragmentation swimming euphausiids
2014/5/19
Sinking of marine snow is a major mechanism of particulate carbon transport from surface waters to the seafloor. Any process altering the abundance or size of marine snow influences carbon flux and fo...
Relating cell-level swimming behaviors to vertical population distributions in Heterosigma akashiwo (Raphidophyceae), a harmful alga
cell-level swimming vertical population distributions Heterosigma akashiwo a harmful algal
2014/5/14
Cell motility may facilitate the formation of harmful algal blooms (HABs) by enabling algal cells to swim to favorable microenvironments that support explosive growth. Motility also augments the forma...
Effect of Temperature Change on Maximum Swimming Speed of Whiting, Merlangius merlangus (Linnaeus, 1758)
Merlangius merlangus temperature effect muscle contraction escape speed
2010/3/30
Seasonal changes in sea temperature levels affect the swimming performance of fish. This study investigates if a change of 5°C from 7 to 12°C in water temperature has a significant effect on the maxim...
