MIT has demonstrated a “Dynamic Shape Display” that can physically change shape to render 3D content. As Fast Company reports, the display is called inFORM, and it’s a large surface that sits atop a series of pins, actuators, and linkages. By moving each actuator, inFORM can move the pin it’s attached to up or down, allowing for a wide range of interactions.
Most of the people you are descended from are no more genetically related to you than strangers are.
From Veronique Greenwood’s fascinating look at just how interconnected our pool of shared ancestry is, and how genetics has changed the way we look at our genealogy: We Are All Princes, Paupers, And Part Of The Human family, at Nautilus.
Previously: Why everyone of European ancestry is related to Charlemagne, and anyone who was alive and reproduced in 3,000 BCE is an ancestor of everyone alive today.
Hello, my cousins. Nice to have you in the family.
Just reinforces my view of humanity as one family.
Young Scientist Invents New Sandbag to Better Protect Against Flooding
When 11-year-old Peyton Robertson saw the devastation caused by Superstorm Sandy, he knew he had to help. But instead of volunteering or donating money, he decided to invent something — a new type of sandbag that can help prevent saltwater flooding in future storms and disasters. The difference is that his sandbags don’t actually contain […]
This kid’s a genius. Game changer in the climate disaster business, which is good, given the expected future.
Will this actually make any women more likely to be morning people? I don’t know, but, SCIENCE!
Now that sharks can walk, is anything safe?!
Why, yes. Actually something is safer now that this walking shark species has been discovered in the waters off the coast of Indonesia: Sharks themselves.
Conservation International’s Mark Erdmann was part of the team that discovered this new “walking shark” (Hemiscyllium halmahera), which plods along the ocean floor using its pectoral and pelvic fins. Sharks lack the buoyant air bladders of bony fish, so that likely has something to do with the floor-dwelling nature of this species.
Indonesia is one of the world’s leading exporters of shark fins, which means that they unnecessarily kill a ton of sharks. In an article detailing the discovery of the walking shark, Erdmann explains how Indonesians are changing their attitudes on shark conservation for the better thanks to discoveries like these.
You get a few hundred bucks for selling shark and ray flesh to eat. But a living creature, serving as a keystone species in the ocean, a cornerstone of entire fishy ecosystems, can be worth as much as $1.9 million to the economy!!
So walk on, proud shark. You’re making a difference. Follow David Shiffman at Southern Fried Science to find out more about shark biology and shark conservation.
