Submission + - SPAM: 3D printed Camera - possible use in surveillance

Taco Cowboy writes: German engineers have created a camera no bigger than a grain of salt that could change the future of health imaging — and clandestine surveillance

Using 3D printing, researchers from the University of Stuttgart built a three-lens camera, and fit it onto the end of an optical fibre the width of two hairs

Such technology could be used as minimally-intrusive endoscopes for exploring inside the human body, the engineers reported in the journal Nature Photonics

The compound lens of the camera is just 100 micrometres (0.1 millimetres) wide, and 120 micrometres with its casing

It could also be deployed in virtually invisible security monitors, or mini-robots with "autonomous vision"

The compound lens can also be printed onto image sensor other than optical fibres, such as those used in digital cameras

An anonymous reader writes: Gold gained on Friday as U.S. data showed signs of rising inflation, boosting the precious metal’s appeal as a hedging strategy versus inflation.
On the Comex division of the New York Mercantile Exchange, gold futures for August delivery traded 0.74% higher on the day and stood at $1 388.05 at 14:13 GMT. The precious metal varied between daily high and low at $1 391.65 and $1 377.85 per troy ounce respectively.

Submission + - A Database of Brains

aarondubrow writes: Researchers recently created OpenfMRI, a web-based, supercomputer-powered tool that makes it easier for researchers to process, share, compare and rapidly analyze fMRI brain scans from many different studies. Applying supercomputing to the fMRI analysis allows researchers to conduct larger studies, test more hypotheses, and accommodate the growing spatial and time resolution of brain scans. The ultimate goal is to collect enough brain data to develop a bottom-up understanding of brain function.

Submission + - Volvo's Electric Roads Concept Points to Battery-Free EV Future (gizmag.com)

Zothecula writes: While quick charging technology installed at strategic points along a planned route might be a good fit for inner city buses, it's not going to be of much use to electric vehicles that stop infrequently. Volvo sees our future long-haul trucks and buses drawing the juice they need from the road itself, making large onboard batteries a thing of the past.

Submission + - Artificial leaf can now "self-heal" and produce energy in remote areas (sciencedaily.com)

RougeFemme writes: The world's first practical artificial leaf already mimiced the ability of real leaves to produce energy from sunlight and water. Now the device is even more suitable for providing people in developing countries and remote areas with electricity. It has the ability to "self-heal" from damage that occurs during the production of electricity. More specifically, it no longer requires pure water. It can now run on the impure, bacteria-laden water found in nature. In earlier versions, "bacteria eventually formed biofilms on the leaf's surface, shutting down production."
