Tiny Wasp Riding on the Backs of Damselfies

Named Hydrophylita emporos—emporos is Latin for “passenger”—the female wasps were observed clinging to abdomens of damselflies, an aquatic insect related to a dragonfly. This acrobatic feat eventually pays off: When the damselfly starts laying its eggs on a submerged leaf, the wasp walks down the abdomen of the damselfly like it’s an exit ramp, enters the water, and then lays its own eggs in the damselflies’ eggs. –National Geographic

Pretty sneaky survival tactic.

Nice to see this series rebooted with Neil DeGrasse Tyson. Looking forward to watching it.

On a side note, Annie bought me two Carl Sagan books for my birthday: “Pale Blue Dot” and “Billions and Billions”. Looking forward to reading them soon.

Photos from Saturn


In this rare image taken on July 19, 2013, the wide-angle camera on NASA’s Cassini spacecraft has captured Saturn’s rings and our planet Earth and its moon in the same frame. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself). At each footprint, images were taken in different spectral filters for a total of 323 images: some were taken for scientific purposes and some to produce a natural color mosaic. This is the only wide-angle footprint that has the Earth-moon system in it. Nasa.gov

Probably some of the most clear photos I’ve seen. Kind of insane that these are real photos of ourselves. Here we are, Earth, suspended in space like a grain of dust.

Microscope Made of Legos, and Actually Works.


“This build was originally inspired by the LEGO X-Pod sets. While trying to find a use for the pod itself, I realized that it was very close to a deep petri dish. I used a planetary gear system to allow both coarse and fine adjustment of the objective “lens”. A little more tinkering and I connected the focus to a magnifying glass and fiber optic light in the eyepiece, so adjusting the focus knobs would actually bring the writing on a LEGO stud in and out of focus.” –Brick Laboratory

Pretty bad ass. Wonder if people will start making telescopes out of them as well.
