A Flyboard is a type of water jetpack attached to a personal water craft (PWC) which supplies propulsion to drive the Flyboard through air and water to perform a sport known as flyboarding. A Flyboard rider stands on a board connected by a long hose to a watercraft. Water is forced under pressure to a pair of boots with jet nozzles underneath which provide thrust for the rider to fly up to 15 metres in the air or to dive headlong through the water.
Segways Without All the Bulk: Self-Balancing Seatless Unicycles Saw a guy today that looked like he was riding a Segway. Until i got a better look and all he was riding on was one wheel, with no handle, and no seat! Looked really neat, easy, stable, convenient. Unlike the Segway. Is this the future of personal transportation?
RoboCup is an annual international robotics competition founded in 1997. The aim is to promote robotics and AI research, by offering a publicly appealing, but formidable challenge.
The official goal of the project:
"By the middle of the 21st century, a team of fully autonomous humanoid robot soccer players shall win a soccer game, complying with the official rules of FIFA, against the winner of the most recent World Cup."
It's neat seeing the technology difference between the 2010 and 2014 versions.
Saccadic masking, also known as visual saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
The phenomenon was first described by Erdmann and Dodge in 1898, when it was noticed during unrelated experiments that an observer could never see the motion of their own eyes. This can easily be duplicated by looking into a mirror, and looking from one eye to another. The eyes can never be observed in motion, yet an external observer clearly sees the motion of the eyes.
Dead Can Dance - Amnesia Quite possibly the most poignant lyrics i've ever heard in a song. Goosebump-inducing for sure.
[...] History is never written By those who've lost The defeated must bear witness to Our collective memory loss
With every generation comes Another memory lapse See the demonstrations of Failing to learn from our past We live in the dreamtime Nothing seems to last Can you really plan a future When you no longer have a past [...]
Parasitic castration is the strategy, by a parasite, of blocking reproduction by its host, completely or in part. For example, Hemioniscus balani, a parasitic castrator of hermaphroditic barnacles, feeds on ovarian fluid, so that its host loses female reproductive ability but still can function as a male.
The male Sacculina looks for a female Sacculina adult on the underside of a crab. He then implants himself into her body and starts fertilizing her eggs. The crab (male or female) then cares for the eggs as if they were its own, having been rendered infertile by the parasite.
When a female Sacculina is implanted in a male crab it will interfere with the crab's hormonal balance. This sterilizes it and changes the bodily layout of the crab to resemble that of a female crab by widening and flattening its abdomen, among other things. The female Sacculina then forces the crab's body to release hormones, causing it to act like a female crab, even to the point of performing female mating dances.
There are even Hypercastrators, a hyperparasite that castrates the parasite it parasitizes
