The crystal mirror-abdomened spider

mirrorspid.jpg

Meet the Mirror Spider, a spider with shiny guanine crystal patches on its back that give it the appearance of the broken glass mosaic you made in arts & crafts class. The shiny parts appear small when the spider is on the move but grow to cover the entire abdomen when at rest (or is it just contracting the non-mirrored parts?). The relatively unknown species was photographed byNicky Bay, who traveled Singapore photo-documenting the arachnid life on … Read More → "The crystal mirror-abdomened spider"

Product designer Jolan Van Der Wiel, who makes bowls, side tables and other items with magnets, and fashion designer Iris van Herpen, who has designed clothes for Bjork and Lady Gaga, teamed up to create silver dresses using the power of magnets. How did they pull it off? By adding iron fillings and resin to the fabric of the dress and using magnets to pull at the filling and resin to create a design. … Read More → "These dresses were made using magnets"

Blood clots could be sucked out of the brain by a robotic device (video)

activecannula.jpg

Designed by a team of physicians and engineers led by Professors Robert J. Webster III and Kyle Weaver, the business end of the device consists of a tube-within-a tube. The straight outer tube is less than one-twentieth of an inch in diameter, and is inserted through a similarly-small hole made in the skull, adjacent to the clot.

Using a CT scan for reference, the cannula’s robotic control unit carefully pushes … Read More → "Blood clots could be sucked out of the brain by a robotic device (video)"

When [Todd] and [Andrew] got their hands on a monitor from an old Asteroids cabinet, they knew what they had to do: build their own vector arcade game.

The guys made their own DAC and Amplifier board that plugs right in to a Nexys2 FPGA dev board. This was after they tested out some 3D drawing code with a gnarly handmade R2R DAC they used to draw and rotate a cube … Read More → "Making vector arcade games with an FPGA (video)"
