Hummingbirds lose power at high altitudes

...hshuler put the hummers through their paces. After weighing and measuring wing size, he filmed them hovering inside a Plexiglas cube to obtain wing beat frequency and stroke amplitude, from which he could calculate the power exerted in normal hovering. The second experiment, however, measured ...

Green tea extract boosts exercise endurance 8-24%, utilizing fat as energy source

...akatoshi Murase said: "We estimate that an athlete weighing 75 kilograms (165 pounds) would have to drink about four cups (0.8 liter) of green tea daily to match the effect in our experiments." "One of our important findings," Murase pointed out, "was that a single high-dose of GTE or its active ingredients ...

New DNA studies verify existence of three right whale species

...ale species." Reaching some 50 feet in length and weighing up to 100 tons, right whales were once abundant along all land masses in the world's temperate latitudes. Right whales were among the first whale species to be hunted commercially, largely due to the fact that the animals were slow swimmers and would...

Radar tracking reveals that butterflies follow decisive flight paths

... Lizzie Cant has attached tiny radar transponders, weighing only about 12mg (4-8% of body weight), to peacock or small tortoiseshell butterflies. This allows her to use harmonic radar to track the butterfly's position accurately up to 1km away. Previous studies had to use visual observation (difficult over 50...
