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.
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.
Researchers are developing computer algorithms to compensate for an individual’s visual impairment, and creating vision-correcting displays that enable users to see text and images clearly without wearing eyeglasses or contact lenses.
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.

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.
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.
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.
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.
Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now, a new wrist-mounted robot can provide a helping hand — or rather, fingers.
On this edition of LabChat, Editor Michelle Taylor delves into the effect toxic heavy metals have on our environment, including land, water and food.

Physicists are working to bring the theory that parallel universes exist— called the multiverse hypothesis— firmly into the realm of testable science.
Researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings question contemporary models of rocky planet formation, including that of Earth.
In this video, ACS examines four scientific facts about money. Did you know those dollar bills in your pocket have a hint of cocaine on them? Or that there are hidden inks and features to prevent counterfeiting? These are just a couple fascinating facts about money to make you scientifically richer.
