Scientists have taken an important step forward in developing a new material using nano-sized magnets that could ultimately lead to new types of electronic devices, with greater capacity than is currently feasible, in a study published today in the journal Science.
Many modern data storage devices, like hard disk drives, rely on the ability to manipulate the properties of tiny individual magnetic sections, but their overall design is limited by the way these magnetic 'domains' interact when they are close together. Now, researchers from Imperial College London have demonstrated that a honeycomb pattern of nano-sized magnets, in a material known as spin ice, introduces competition between neighbouring magnets, and reduces the problems caused by these interactions by two-thirds.
They have shown that large arrays of these nano-magnets can be used to store computable information. The arrays can then be read by measuring their electrical resistance. Building Hunted’s AI: Some Fundamental Elements. So Jim has been going on about how dynamic AI combat is the heart of Sir, You Are Being Hunted – let’s look at what that means from the perspective of the development work we are actually doing.
I’ve illustrated this with a few shots from the AI testscenes build, which shows some of the “scene view” elements of Unity’s editor. Obviously the scenery and so forth is placeholdery and not actually intended to be seen as the sort of scale or density we’re expecting for a final game. One of the key features we wanted in Hunted, was the ability for enemy AI to behave as autonomously as possible. The Black Queen Hypothesis: A new idea on evolution.
Microorganisms can sometimes lose the ability to perform a function that appears to be necessary for their survival, and yet they still somehow manage to endure and multiply.
How can this be? The authors of an opinion piece appearing in mBio®, the online open-access journal of the American Society for Microbiology, on March 27 explain their ideas about the matter. They say microbes that shed necessary functions are getting others to do the hard work for them, an adaptation that can encourage microorganisms to live in cooperative communities.
The Black Queen Hypothesis, as they call it, puts forth the idea that some of the needs of microorganisms can be met by other organisms, enabling microbes that rely on one another to live more efficiently by paring down the genes they have to carry around. In these cases, it would make evolutionary sense for a microbe to lose a burdensome gene for a function it doesn't have to perform for itself. Watkins Glen State Park. Watkins Glen State Park is the most famous of the Finger Lakes State Parks located on the edge of the village of Watkins Glen, New York, south of Seneca Lake in Schuyler County.
The main feature of the park is the hiking trail that climbs up through the gorge, passing over and under waterfalls. The park has a lower part that is next to the village and an upper part that is open woodland. Watkins Glen State Park is in a 400-foot-deep narrow gorge cut through rock by a stream that was left hanging when glaciers of the Ice age deepened the Seneca valley, increasing the tributary stream gradient to create rapids and waterfalls wherever there were layers of hard rock.
The rocks of the area are sedimentary of Devonian age that are part of a dissected plateau that was uplifted with little faulting or distortion. They consist mostly of soft shales, with some layers of harder sandstone and limestone. Featured Workspace News, Videos, Reviews and Gossip - Lifehacker.

Doodling in Math: Spirals, Fibonacci, and Being a Plant. Turn a Magazine Holder into a Corner Shelf. Treehouse B&B proprietor tells all. This 17-minute mini-documentary introduces Michael Garnier, proprietor of the Out'n'About Treehouse Resort in Oregon.
Garnier is a thoughtful and salty woodcrafter who's put a lot of thought into the right way to build a treetop B&B, and his guided tour of his little hotel with its Ewok-style treehouses is a delight. Over the years, Garnier has become legend in his industry and helped invent a better way to build a treehouse. Instead of bolting wood to wood (i.e. beams to the tree), Garnier and his colleagues at the World Treehouse Conference (an event he used to host) developed a way to attach steel bolts and cuffs to the tree. Dubbed the Garnier Limb (or G.L.), this open source design can support 8,000 pounds.
Garnier sells GLs of all different types as well as plans to build your own treehouse. Watch Captain Planet go insane, kill everyone. The Wolfe's Den treehouse. [Video Link] MAKE magazine's Derek "Deek" Diedricksen shows how he built this cool treehouse.
This triangular treehouse was assembled in the Catskills over two weekends, and stands as one of the larger projects Deek's tackled for the show. His only given parameters for the design: "It must receive a good deal of natural light, and have enough space to sleep two (floor space)". In February Deek's new book is coming out. It's called: Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts.See more MAKE videos here.
