Gigabot 3D Printing: This is Huge! by re:3D Share this project Done Share Tweet A Better Way to Get Hydrogen from Water An experimental approach to splitting water might lead to a relatively cheap and clean method for large-scale hydrogen production that doesn’t require fossil fuels. The process splits water into hydrogen and oxygen using heat and catalysts made from inexpensive materials. Heat-driven water splitting is an alternative to electrolysis, which is expensive and requires large amounts of electricity. The new approach, developed by Caltech chemical-engineering professor Mark Davis, avoids the key problems with previous heat-driven methods of water splitting. It works at relatively low temperatures and doesn’t produce any toxic or corrosive intermediate products.

Printrbot jr assembly part 1 Finally got some time to work on assembling the actual printer. Started out with going through the LC parts to check if they were all there. Also snapped some photos of other components: printrbot Screws, nuts, etc. Ants Are Capable of Changing Their Priorities Ants are highly social and they must work together to provide food and shelter for the entire colony. It has recently been discovered that there is no set hierarchy on the importance of these aspects, as ants are capable of learning from previous experience to assess a current situation and determine what is most important at that time. Takao Sasaki and Stephen C. Pratt from Arizona State University’s School of Life Sciences have published their findings in Biology Letters. The study was focused on Temnothorax rugatulus, an ant species native to the west coast of North America, stretching from British Colombia, Canada down to Arizona in the Sonoran Desert. Ants have many options to consider when looking for a new place to live.

Fosterbot, a Makerbot Thing-o-Matic derived 3D Printer Jun.3, 2012 John Foster, "By day I am a mechanical engineer at a fiber optics company. By night I make everything I can figure out how to make." created Fosterbot, a cute 3D printer derived from Makerbot's Thing-o-Matic. "It is better, stronger and faster", said John. He published a nicely written instructables and all the necessary CAD files on Thingiverse free for everyone to download. For those of you feeling constrained by your build volume ever since the Replicator was released, these modifications increased my build envelope dimensions to 150mm on the x-axis, 185mm on the y-axis, and 132mm on the z-axis.

All-carbon solar cell harnesses infrared light About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — energy that conventional silicon-based solar cells are unable to harness. But a new kind of all-carbon solar cell developed by MIT researchers could tap into that unused energy, opening up the possibility of combination solar cells — incorporating both traditional silicon-based cells and the new all-carbon cells — that could make use of almost the entire range of sunlight’s energy. “It’s a fundamentally new kind of photovoltaic cell,” says Michael Strano, the Charles and Hilda Roddey Professor of Chemical Engineering at MIT and senior author of a paper describing the new device that is being published this month in the journal Advanced Materials.

Why Animals "Adopt" Others, Including Different Species A feel-good tale of sperm whales "adopting" a deformed bottlenose dolphin made an Internet splash this week . The story resonated with readers, including Reddit commenter Fallapoo , who said: "I see a Disney movie in the works." But the marine mammals aren't the only ones that form odd alliances, experts say. Such adoptions are relatively common among domestic animals, and occasionally seen in the wild, according to Jenny Holland, author of the 2011 book Unlikely Friendships . ( Read a Q&A with Holland about her book .) Some examples include a dog that nursed a baby squirrel as part of her own litter, captive apes that treated cats like infant apes, and a dog that watched over a baby owl , Holland said by email. And in her forthcoming book, Unlikely Loves , Holland will feature a Dalmatian that adopts a calf that happens to wear Dalmatian-like spots, a goat that helps a young giraffe learn self-confidence, and a hen that sits on "her" pups to keep them warm.

untitled Mini-cars, bracelets, cookie cutters, desserts, shirts – the possibility of what you can make on even a small desktop (FDM) 3D printer is nearly endless. Almost as endless, is the list of possibilities of who can design these amazing toys, trinkets and tools. Thanks to free tools, creative people, and the art of the search engine plus YouTube tutorial combination – we’re finding that the face of these 3D designers is changing, evolving and just as exciting as the designs that they create. So, who are the pioneers who are out there in this new 3D printing wave taking over the maker space? Who are our 3D Designers? Our designers are: hobbyists – looking for ways to make some extra money (36%), Full-Time Designers (44%), Part-Time Designers (14%), and Hobbyists – who are in it for the fun of it (5%).

Red Wine, Tartaric Acid, and the Secret of Superconductivity  Last year, a group of Japanese physicists grabbed headlines around the world by announcing that they could induce superconductivity in a sample of iron telluride by soaking it in red wine. They found that other alcoholic drinks also worked–white wine, beer, sake and so on–but red wine was by far the best. The question, of course, is why. What is it about red wine that does the trick?
