Artificial blood ‘will be manufactured in factories’
Wellcome Trust-funded stem cell research has produced red blood cells fit for transfusion into humans, paving the way for the mass production of blood.
"KitRex began as a homework assignment where I was asked to research a manufacturing process and demonstrate it in a unique way. I decided to research Industrial Origami, and over the course of 50 hours I designed, cut, and built a wearable 15-ft long velociraptor out of cardboard. I took him to a costume ball, and when I tromped into the room, literally everyone stopped to stare. He was the star of the evening, and everyone wanted one. I knew I had to do something."
Lisa then started (and successfully funded) a KitRex Kickstarter project to help her mass-produce an adorable 3-foot-long KitRex (since most people don’t have the space for a 15-ft paper dino). After months of prototyping and testing with kids between 8 - 12 years old, the final KitRex was born as a bristol board model that’s easily flat-packed and shipped anywhere (But you have to add your own googly eyes). A few lucky Kickstarter contributors were rewarded with giant 15-foot KitRexes of their very own.
Lisa isn’t quite ready to ship the KitRex, but for the time being you can click here to download a free pattern that fits on a standard 8x10 sheet of paper. It’ll be like playing with a dino hatchling.

How vision makes sure that little fish do not get carried away
Our eyes not only enable us to recognise objects; they also provide us with a continuous stream of information about our own movements. Whether we run, turn around, fall or sit still in a car – the world glides by us and leaves a characteristic motion trace on our retinas. Seemingly without effort, our brain calculates self-motion from this “optic flow”. This way, we can maintain a stable position and a steady gaze during our own movements. Together with biologists from the University of Freiburg, scientists from the Max Planck Institute of Neurobiology in Martinsried near Munich have now discovered an array of new types of neurons, which help the brain of zebrafish to perceive, and compensate for, self-motion.
It is a zebra fish!
Close-ups of butterfly wing scales! You should definitely click on these images to get the full detail.
I’ve paired each amazing close-up (by macro photographer Linden Gledhill) with an image of the corresponding butterfly or moth. The featured lepidoptera* are (in order of appearance):
- Madagascar diadem Hypolimnas dexithea (photo by Michel-Georges Bernard)
- Comet moth Argema mittrei (photo by Axel Strauß)
- Sunset moth Chrysiridia rhipheus (photo from Wikimedia Commons)
- Giant Blue Morpho Morpho didius (photo by Didier Descouens, Muséum de Toulouse)
- Rippon’s Birdwing Troides hypolitus (photo by Robert Nash, Ulster Museum)
*Lepidoptera (the scientific order that includes moths and butterflies) means “scaly wing.” The scales get their color not from pigment - but from microscopic structures that manipulate light.
Australia’s Stay in School Campaign ain’t fucking around.
THIS IS THE FUNNIEST THING I HAVE EVER SEEN I AM ACTUALLY CRYING
i need an hour or two to recover after watching this
I am pissing my fucking pants im sorry goddamn australia
