Researchers have used high-speed video and numerical simulation to capture the effects of aerodynamics on jump roping. After videoing an athlete jumping rope and constructing a jump roping robot (shown Keep reading

Drafting Flags
Wired Science has published a gallery of fluid dynamics photos and videos, several of which have been featured here previously. There’s some neat stuff there, well worth checking out. # Keep reading
White Hole Analogues
A white hole–the cosmological opposite of a black hole–is a singularity from which matter emerges but which matter can never enter from beyond the event horizon. Hydraulic jumps, those rings Keep reading
Venom Properties
Most venomous snakes deliver venom to their prey via grooves in their fangs, rather than through a pressurized bolus through hollow fangs. New research shows that these venoms are shear-thinning Keep reading
Frost on Superhydrophobic Surfaces
Frost formation and ice adhesion on superhydrophobic surfaces For anyone with further interest in the ice formation on superhydrophobic surfaces story we posted recently, the published paper is currently offered Keep reading
How Cats Drink
While humans use suction and dogs scoop water using their tongues*, cats use a dainty fluid mechanism to drink. Researchers used high-speed video to find that cats drink by touching Keep reading
Wind Turbines and Weather
A new study reports that wind turbine farms may be changing local surface temperatures, resulting in warmer temperatures at night and cooler temperatures during the day. The result is neither Keep reading
Sailing Faster than the Wind
Is it possible to create a vehicle that uses the wind to move itself directly downwind faster than the wind does? Strangely enough, it is. The concept has been the Keep reading
A couple more links on flying fish
Wired Science and 80 beats on Discover have a few more summaries on the recent flying fish paper and its findings.
How to Grow Straight Icicles
New research suggests that icicles grow straighter when exposed to moving air while exposure to still air can cause icicles to sprout at their tips. To grow icicles, the researchers Keep reading
