App Teaches Kindergartners to Code

July 31, 2014 7:00 am | by App Teaches Kindergartners to Code, MIT Videos Comments

Can children learn to code at the same age they’re learning to tie their shoes? That’s the idea behind ScratchJr, a free iPad app released this week. Children ages 5 to 7 can program their own interactive stories and games. In the process, they learn how to create and express themselves with the computer, not just interact with it.

Hummingbirds vs. Helicopters: Engineers Compare Flight Dynamics

July 31, 2014 7:00 am | by Stanford Univ. Videos Comments

A study reveals that the spinning blades of micro-helicopters are about as efficient at hovering as the average hummingbird. The experiment involved spinning hummingbird wings – sourced from a pre-existing museum collection – of 12 different species on an apparatus designed to test the aerodynamics of helicopter blades.

Glow in Space is a Hot Bubble in Our Galaxy

July 28, 2014 1:33 pm | by Univ. of Miami Videos Comments

A recent study shows that diffuse X-ray background is dominated by the local hot bubble of gas (1 million degrees), with, at most, 40 percent of emission originating within the solar system. The findings should put to rest the disagreement about the origin of the X-ray emission and confirm the existence of the local hot bubble.

Droplet-trapping Material Could Ease Water, Energy Crisis

July 25, 2014 7:00 am | by NSF Videos Comments

Small-scale advances in fluid physics, materials engineering and nanoscience have brought scientists one step closer to mimicing the way a desert beetle collects and drinks water. Understanding how liquids interact with different materials can lead to more efficient, inexpensive processes and products, and might even lead to airplane wings impervious to ice and self-cleaning windows.

Glucose Helps Alaska Frogs 'Overwinter' to Survive

July 24, 2014 7:00 am | by Univ. of Fairbanks Videos Comments

Repeated freezing and thawing might not be good for the average steak, but each fall it might help wood frogs prepare to survive Alaska’s winter cold. Frogs prevent the freeze-pop effect by packing their cells with glucose, a kind of sugar that reduces drying and stabilizes cells, a process scientists call cryoprotection.

Bamboo as Engineered Building Material

July 23, 2014 8:29 am | by Jennifer Chu, MIT Videos Comments

Scientists are looking for ways to turn bamboo into a construction material more akin to wood composites, like plywood. The idea is that a stalk, or culm, can be sliced into smaller pieces, which can then be bonded together to form sturdy blocks—much like conventional wood composites.

Gold Nanoparticles Take Neuron Route to Deliver Drugs

July 22, 2014 7:00 am | by MIT, Anne Trafton Videos Comments

A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons.
