Given the schematic for a simple circuit, here’s how to make it a real circuit with the base components, some conductive thread, and a 3D printer — no solder, no etching chemicals, no sending away for anything, Instructables explains in a how-to tutorial.

Nanoporous ceramic membranes may create an interface between human tissues and medical devices that is free of protein buildup, leading to new dialysis devices and other revolutionary medical implants, a new study led by North Carolina State University has found.

Vanderbilt University researchers have discovered a method that uses laser light, rather than electricity, to stimulate and control neurons.
They discovered in an experiment with rats that low-intensity infrared laser light can activate specific nerves, exciting a leg or even individual toes without actually touching the neurons. Immediately following the experiment, the rats regained full use of their legs with no signs of weakness or damage.… read more

British scientists have discovered a way to make microchips smaller and faster by creating light-emitting regions in the silicon. “The power of chips doubles every few years but that will stop happening soon, because as you make them smaller the complexity of the contacts and wire that connects them doesn’t scale — it stays the same,” said Kevin Homewood, a professor of optoelectronics at the University of Surrey. The achievement,… read more
New functional and imaging-based diagnostic tests that measure communication and signaling between different brain regions may provide valuable information about consciousness in patients unable to communicate.
The new tests, described in an open-access survey article, are functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS) combined with electroencephalograpy (EEG), and response to neuronal perturbation, measuring, for example, sensory evoked potentials (ERP).
Disorders of consciousness such as coma… read more

Stanford University AI researchers have developed software that allows anyone to insert a video or still photo on almost any planar surface in an existing video.
A “3D Surface Tracker Technology” algorithm first analyzes the video, with special attention paid to the section of the scene where the new image will be placed. The color, texture and lighting of the new image are subtly altered to blend… read more

A robot that tricks its opponent in a game of hide and seek is a step towards machines that can intuit our thoughts, intentions and feelings.

A team of researchers at MIT and the University of California at Berkeley has found a simple, inexpensive treatment that may help to unleash graphene’s potential. Currently, many suggested uses of graphene require treatments that can be expensive and difficult to apply predictably.
The new method is described in a paper published in the journal Nature Chemistry, co-authored by MIT doctoral students Priyank Kumar and Neelkanth Bardhan,… read more

IBM Almaden Research Center has developed a next-generation search technology, called WebFountain, that lets users ask specific questions in complete sentences — something today’s search engines have trouble handling.
WebFountain can whittle down billions of pages of unstructured data from the entire Web in real time, rapidly retrieving and analyzing only the most relevant pages. Geared for corporate applications, WebFountain spots online trends as they emerge, identifies patterns –… read more

Researchers at the University of California, San Diego have created silicon chips that support fully functioning liver cells.
“We’re exploring a new generation of devices in which we can maintain cells by controlling the architecture, temperature and chemical environment, and in which we can use sensors located on the same chip to monitor the health of cells,” says Sangeeta N. Bhatia, a physician and an assistant… read more
Navy pilots and other flight specialists soon will have a new “smart machine” installed in training simulators that learns from expert instructors to more efficiently train their students.
Sandia National Laboratories’ Automated Expert Modeling & Student Evaluation (AEMASE, pronounced “amaze”) is being provided to the Navy as a component of flight simulators.
Components are now being used to train Navy personnel to fly H-60 helicopters and… read more

Intel cofounder Gordon Moore, who coined Moore’s Law (the number of transistors that can be packed into an integrated circuit will double every year), believes this doubling will slow down sometime between 2010 and 2020. He doesn’t see a solution in the works.
In the meantime, what should we do with this increased power? “The one capability that to me will make a qualitative difference in how we do… read more

University of Massachusetts researchers have patented “personal information maps” that cluster related documents and information, and superimpose the results on relevant background images or 3D objects in a manner akin to how our minds store and organize information.

The power grid is vulnerable to manipulation or sabotage, according to a study revealed this week.
Attackers could manipulate power-grid data by breaking into substations and intercepting communications between substations, grid operators, and electricity suppliers. This data is used by grid operators to set prices for electricity and to balance supply and demand, the researchers say. Grid hackers could make millions of dollars at the expense of electricity consumers… read more
