philetus writes "New Scientist has up a story on Posey, a hub-and-strut construction kit that senses its configuration and communicates it wirelessly to a computer. From the article: 'If you gave Lego brains, you might get something like Posey, a new hands-on way of interacting with computers developed at Carnegie Mellon University, Pittsburgh, US. When Posey's plastic pieces are snapped together, an exact copy of the construction appears on a computer screen. Every twist of, say, a stick figure's arm is mirrored in 3D modelling software ... Each piece's plastic shell is stuffed with chips and devices for processing these signals. They are sent wirelessly to a computer using a low-power protocol called ZigBee. This means, bending Posey's pieces can make objects on-screen respond in real time. Right now, each custom-made piece has about US$50 (£25) worth of parts, Weller estimates. But if mass produced, it could be much cheaper.'"

ludwigvan968 writes "The ACTLab at the University of Texas at Austin is making waves with its Weird Science class. The link is to the TA's blog with documentation of some of the projects: a laser harp, a 3D environment constructed with fog and an LCD projector, and a 'water bridge' using a 50,000-volt transformer. Next semester, they're introducing a new class called 'Disruptive Technologies.'"

coondoggie writes to tell us that NASA has captured some pretty impressive images of the Alluring noctilucent (or "night-shining") clouds. These clouds are made up of ice crystals and dust and are formed at high altitudes near the poles. "Very little is known about how these clouds form over the poles, why they are being seen more frequently and at lower latitudes than ever before, or why they have been growing brighter. AIM will observe two complete cloud seasons over both poles, documenting an entire life cycle of the shiny clouds for the first time. 'It is clear that these clouds are changing, a sign that a part of our atmosphere is changing and we do not understand how, why or what it means,' stated AIM principal investigator James Russell III of Hampton University, Hampton, Va. 'These observations suggest a connection with global change in the lower atmosphere and could represent an early warning that our Earth environment is being changed.'"
