Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton
From the surface, the ocean appears to be vast and uniform. But beneath the surface, tiny animals called zooplankton are swept into clusters and patches by ocean currents. The very survival of many zooplankton predators--from invertebrates to whales--and the success of fishermen catches can depend on their success at finding those patches. For almost a century ocean scientists have suspect...Swimming with dolphins can alleviate depression
Swimming with dolphins is an effective treatment for mild to moderate depression, say researchers in this week's BMJ. The study was carried out in Honduras and involved 30 patients diagnosed with mild or moderate depression. Hal...U. of Colorado researcher identifies tracks of swimming dinosaur in Wyoming
With their long stalks and feathery arms, marine animals known as sea lilies look a lot like their garden-variety namesakes. Perhaps because of that resemblance, scientists had always assumed that sea lilies stayed rooted instead of moving around lik...Paramecia adapt their swimming to changing gravitational force
For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking. Now physicists Karine Guevorkian and James Valles of Brown University have worked out a way to turn gravity on its head and see how the creatures respond. The researcher...Swimming 'to the left' gets bacteria upstream, and may promote infection
Yale engineers who study both flow hydrodynamics and how bacteria propel themselves report that one reason for the high incidence of infections associated with catheters in hospital patients may be that some pathogenic bacteria swim "to the left," in a study published in Physical Review Letters. "Escherichia coli (E. coli) and some other pathogenic bacteria with flagella interact with th...Swimming in Chlorinated Pools Raises Asthma Risk
Children who swim in chlorinated pools weekly or fortnightly have a higher risk of developing lung diseases including asthma, a study in the British medical journal Occupational and Environmental Medicine found. The inhalation of chemicals used to destroy microbiological germs in swimming pools may be responsible for the surge of childhood asthma in developed countries, according to Alfre...Swimming With Dolphins Can Help Ease Depression
After sessions of counselling, loads of anti-depressant medication and lifestyle change may be it is time for you to go to the dolphin city to enjoy a splendid ride with a dolphin to help ease your depression.// This new form of treatment supports the theory of biophilia that illustrates the dependence of human health on our relationships with the natural environment. Nearly 30 patien...Children Face Risk While Swimming
Children may end up developing chronic lung problems and asthma if they are taught to swim before the age of two, according to Alfred Bernard, the professor of toxicology at Belgium's Catholic University of Louvain.// He also added that the levels of the irritant trichloramine were 50% higher in the air above indoor paddling pools than in adult pools, and that his recent study of 341 schoolchildr...Use Of Indoor Swimming Pools Linked To Development Of Asthma In Children
A new research suggests that children who use an indoor swimming pool may be at increased risk of developing asthma.// The study by the Belgian researchers of the Catholic University of Louvain, which appears in Occupational and Environmental Medicine, has found that the rates of childhood asthma and wheezing rose by around 2-3% for every indoor swimming pool per 100,000 people. The r...
