Two world records fall at World Cup swimming meet in Stockholm
Canadian Press 11/12/08
South African swimmer Cameron van der Burgh set his third world short-course record in four days at a World Cup swimming meet Tuesday.
Also, Peter Marshall regained the 100-metre backstroke
record in 49.94 seconds, breaking American countryman Ryan Lochte's time of
49.99 from the 2006 world championships. Lochte took the record from
Secret to Penguin Locomotion Revealed
Yahoo 11/13/08
Penguins are wobbly on land, but their extreme underwater agility involves the perfection of a twisting wing motion that is just now coming to be understood. A new study found that by twisting their wings while pumping them under water to swim, the birds are able to vary the thrust of their flapping and increase control over their movements. The motion is so useful researchers are testing it out on prototypes for new underwater spy vehicles.

Instead of kicking, PowerSwim calls for a kind of undulation as its hinged foils pivot up and down. Similar to the way a dolphin or tortoise pumps its fins, this motion generates both lift and thrust. And while artificial fins operate within the swimmer’s own wake (they form a kind of expanding cone, starting at a swimmer’s shoulders), the PowerSwim’s lead foil—or propulsor foil—sweeps through the water just outside that wake.
The Speedo LZR racer: feedback on a developing debate
The Science of Sport 3/25/08
This suit is making waves in the swimming world, since it has been worn for 9 out of 9 world records in the pool this year! Some coaches believe the issue of fairness needs to be debated, with calls for ethics debates around it.
Vortices and Propulsion – Arellano

A review of the general theory of swimming propulsion is presented relating this with knowledge about vortices in steady and unsteady flow conditions.
Physics NYU
I have been working on physical problems in fluid dynamics that are related to biology and geophysics. To be more specific, I study the flapping of flags in the wind (this problem is closely related to the swimming of fish), the thrust generation and the flapping locomotion of birds and fish, thermal convection in the geophysical context (the coupling between continents and the convective mantle), etc.
