Squishy robots. In the movie “Terminator 2,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed.

Squishy robots

Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat. The material — developed by Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and her former graduate student Nadia Cheng, alongside researchers at the Max Planck Institute for Dynamics and Self-Organization and Stony Brook University — could be used to build deformable surgical robots. The robots could move through the body to reach a particular point without damaging any of the organs or vessels along the way.

After building a homebrew x-ray backscatter imager, [Ben Krasnow] realized he had nearly all the components to build his own CT scanner, able to make a 3D model of the inside of a frozen chicken.

[Ben Krasnow] builds a CT Scanner

Basically, a CT scanner takes dozens of x-rays of an object and reassembles them with the help of fancy algorithms to allow doctors to peer inside a human body. The CT scanners you’ll find at your local hospital are monstrous devices, rotating an x-ray tube and sensor around a patient with the help of some very heavy duty electromechanical engineering. [Ben] wanted to keep his build rather small, so instead of rotating the x-ray tube and screen around an object, he simply made a stepper motor-driven lazy suzan to rotate his frozen bird. [Ben] set a digital camera off to the side of his build and captured 45 images of a rotating chicken.

If you’re looking for a taste of what it will be like to develop for Google Glass, the company posted a video demonstrating the hardware and a little bit of the API on Thursday.

Angling to develop for Google Glass? Google gives some insight

Timothy Jordan, a senior developer advocate at Google, gave a talk at SXSW in early March that lasted just shy of an hour and gave a look into the platform. Google Glass bears more similarity to the Web than the Android mobile operating system, so developing for it is simpler than creating an Android application. ER doctors use Google Glass and QR codes to identify patients.

A tech-savvy hospital in Boston developed a custom information-retrieval system for Google Glass, which lets ER doctors scan a QR code on the wall of each room to call up information about patients.

ER doctors use Google Glass and QR codes to identify patients

Dr. John Halamka, CIO of Beth Israel Deaconess Medical Center, described the system today in his blog (a cached version is here as the original post seems to have been shortened significantly): In the Emergency Department, we’ve developed a prototype of a new information system using Google Glass, a high tech pair of glasses that includes a video camera, video screen, speaker, microphone, touch pad, and motion sensor.Here’s how it works.When a clinician walks into an emergency department room, he or she looks at [a] bar code (a QR or Quick Response code) placed on the wall. Google Glass immediately recognizes the room and then the ED Dashboard sends information about the patient in that room to the glasses, appearing in the clinician’s field of vision.

Making Makers. Together, Kids Learning Code, Maker Kids, TIFF and Toronto Public Library, have developed comprehensive, maker curriculum for educators who work in formal and informal learning environments with the objective of increasing Toronto youth access and engagement with advanced technology and digital tools!

Making Makers

Our workshops and activities allow youth to create something with purpose, driven by their own vision and also empower teachers to be makers. We are hosting Train the Trainer Symposiums wherein the educators can learn how to run and modify activities by doing them.

The Always Up-to-Date Guide to Building a Hackintosh (OS X 10.9) The Seagate Kinetic Open Storage Vision. The World of Storage Has Changed: Data Types, Access Models, Demand and Use Cases Over the past decade, the explosive growth of large-scale, data-driven applications has begun to shift the nature of enterprise storage infrastructure fundamentally. The traditional paradigm of hardware-centric, file-based systems is moving aside to make way for new software-defined, object-based approaches. The new paradigm is an object-oriented one: a world of pictures, movies, ecommerce and Web data, search, and games, and archives of all of these.

In this world, objects (information) are written, read and deleted but never modified. Increasingly, systems and data centers are designed for capacity rather than performance. In addition, because Ethernet is the undisputed fabric of data centers and application traffic, it has unsurprisingly emerged as the backbone of storage infrastructure. This growth is driven by the increasing prominence of mobile, social, cloud computing and big data. Figure 2. Scale. High-altitude balloon. High-altitude balloons are unmanned balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between 60,000 to 120,000 feet (11 to 23 mi; 18 to 37 km).

During 2002, a balloon named BU60-1 attained 53.0 km (32.9 mi; 173,900 ft).[1] The most common type of high altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. These balloons are launched into what is termed "near space"—- the area of Earth's atmosphere where there is very little air, but where the remaining amount generates too much drag for satellites to remain in orbit.

Could a Balloon Fly in Outer Space? Here’s the sort of crazy idea that animates our office conversation at Scientific American. It all started with my colleague Michael Moyer’s joke that a certain politician could build his moon base using a balloon: just capture the hot air and float all the way up.

Programmer en javascript directement sur votre Raspberry Pi Si vous aimez votre Raspberry Pi, vous avez peut-être décidé de vous lancer dans le développement d'applications pour ce mini ordinateur. Mais avant de faire tourner un programme sur le Pi, il faut d'abord le développer sur son propre ordinateur, mettre les sources sur le Rasberry, puis compiler les sources, puis tester, puis corriger les bugs sur l'ordinateur, puis envoyer à nouveau les sources sur le Raspberry Pi, les recompiler, voir ce que ça donne, ainsi de suite.

Ce genre d'aller-retour prend du temps et ce n'est pas très agréable.

Cars. Image. Computers. Tablets. Phones. Impression 3D. Robotics. Communauté: The Ben Heck Show. Nanotechnologies dans le textile. Résumé : Les nanotechnologies ont permis de générer toutes sortes de nanomatériaux aux propriétés singulières, qu’il est opportun de marier aux fonctionnalités intrinsèques des textiles. Ainsi nanoparticules d’argent aux effets antibactériens, membranes à base de nanofibres et revêtements nanostructurés imitant la feuille de lotus se retrouvent déjà dans des produits textiles de grande consommation. Pour réaliser ces nanotextiles, les entreprises du secteur ont deux choix : incorporer des nanomatériaux préfabriqués avec les outils traditionnels ou faire évoluer cet outil industriel vers la production de nanocomposés (nanocouches, nanofibres principalement) directement intégrés aux textiles.

Quelle que soit la stratégie adoptée, elle doit s’accompagner des précautions nécessaires à la manipulation de ces nouveaux produits, en particulier aujourd’hui dans un cadre règlementaire toujours en cours de définition.
