If anyone else with a MagnetU has a profile that matches yours sufficiently, the device will alert both of you via text and/or an app. It also links to Facebook, Linkedin, Twitter and other online social networks.
The social networks market is teeming with “mobile social networking” companies that want to bring the same phenomenon to the 3.3 billion cellphone subscribers, a number that far surpasses the total of Internet users.
The advantage over computer-based communities, they believe, is the ability to know where a cellphone is, thanks to global positioning satellites and related technologies.
myExperiment, the social networking site for scientists, has set out to challenge traditional ideas of academic publishing as it enters a new phase of funding.
Vivaty of Menlo Park, California, is creating a hybrid of conventional social networking sites such as Facebook and virtual worlds like Second Life.
To be offered to Facebook users, Vivaty users will get access to a virtual room where they can adorn the walls with photos, watch a virtual television that plays YouTube, invite friends over to join them, and chat via 3D avatars.
Random networks, such as the Internet and global flight connections, have the potential for extreme behavior never seen before, suddenly gaining a central backbone of connections that make it simple to travel between any two points, researchers at the University of California at Santa Cruz and elsewhere have found.
The addition of just one link triggers an instantaneous phase change and the network becomes fully connected.
Miniature, ultra-flexible electrodes could be the answer to more successful treatment for Parkinson’s diseases, according to Professor Philippe Renaud of the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.
Some 90,000 patients per year are treated for Parkinson’s disease, a number that… read more
In a new study, the large-scale ongoing Framingham Heart Study has found that drinking more than one soft drink a day, whether regular or diet, may be linked to an increased risk of developing heart disease, via an increase in metabolic syndrome.
Metabolic syndrome is a group of symptoms such as excess waist circumference, high blood pressure, elevated triglycerides, low levels of high-density lipoprotein (HDL or “good” cholesterol) and… read more
North Carolina State University researchers have developed a soft memory device design that functions well in wet environments and has memristor-like characteristics, opening the door to new types of smart biocompatible electronic devices.
A memristor (“memory resistor”) is an electronic device that changes its resistive state depending on the current or voltage history through the device.
The ability to function in wet environments and… read more
Miniaturized robots that could one day function medically inside the human body are being designed by researchers in Trieste and Catalonia.
The robots of the future will be increasingly like biological organisms, with the same “softness” and flexibility as biological tissues, according to Antonio De Simone from SISSA (the International School for Advanced Studies of Trieste) and Marino Arroyo from the Polytechnic University of Catalonia, who have… read more
Several Harvard University labs in collaboration with Trinity College Dublin have developed the Soft Robotics Toolkit — an online treasure trove of downloadable open-source plans, how-to videos, and case studies to assist users in the design, fabrication, modeling, characterization, and control of soft robotic devices.
With the advent of low-cost 3D printing, laser cutters, and other advances in manufacturing technology, soft robotics is emerging as an increasingly… read more
If robots are going work around humans, they will have to be softer and safer. A Harvard team has designed a new actuator with that in mind. Its movements are similar to those of a human bicep muscle, using vacuum power to automate soft rubber beams. Like real muscles, the actuators are soft, shock-absorbing, and pose no danger, according to the researchers.
The work is led by… read more
