Virtualizing Healthcare >> Google Deepmind: Should patients trust the company with their data?
A BBC article looking at the pros and cons of Google's DeepMind AI system for sifting through patient's medical data looking for missed connections between symptoms. It consideres the difficulties inherent in letting a private company comb through that most sensitive data, raising legal and privacy concerns along the way.
Telehealth >> Toothscan Dental Health Technology
A telehealth device just entering the market at time of writing, offers the chance to perform dental health scans at home, providing a daily record of tooth health to aid a dentist, or perhaps more pertinently, flag up a warning if a tooth is starting to degrade â€“ before the pain sets in.
Computer Aided Manufacture >> 3D Printing Body Parts and Teeth: What's Next?
An overview of how 3D printed prosthetics are changing dentistry. Covering in overview form, several different technologies for creating teeth: Everything from creating custom bridges to exacting perfection, to creating teeth that kill bacteria in the teeth around them, just by being used.
Computer Aided Manufacture >> Have You Heard of the 3D Printed Tooth That Kills Bacteria?
When most people think of 3D printing, they think of the printer using plastic, resin, or maybe some metals. Yet, as this article demonstrates, you can 3D print with almost anything providing it can be reduced to a powder form. In this instance, a 3D printed tooth is made of a resin infused with antimicrobial quaternary ammonium salts. This means they exist right through the tooth, and as the outer surface is worn away by use, more and more antimicrobial material is released into the mouth.

Latest Term: D-MRI
D-MRI is the short term for Diffusion MRI (sometimes termed Diffusion-weighted magnetic resonance imaging). It is a medical imaging technique specifically concerned with using the diffusion of water molecules throughout both the blood and bodily tissues to build up a contrast map of a living, organic body.
This creates a microscopic-level detail map about systems in the body, particularly as the patterns of water diffusion are recognisable for what they are: Namely which tissue structure from the gaps in diffusion, exists in a given location.
As such, diffusion MRI is an excellent tool for mapping neurological structures in particular, making it that much easier to see how the structures are laid out, and making connecting with a particular structure via implant or interface much more feasible than without.
As such, its primary usage in relation to virtual and augmented reality is to map out precisely the locations of given neurological structures, in order to identify the optimal location for a brain implant in a later surgery. This is a process known as tractography, and one which has benefits across all of neuroscience.
Additionally, as a MRI variant, D-MRI is also used more directly as a virtual reality data input, as the results from the scan can be compiled by many medical data imaging systems into a medical mirror world, a virtual environment precisely replicating the inside of a region of a patient's body via mappingthe water diffusuion, allowing medical professionals to interact with the datsa in three dimensions, isolating the best route for a future surgery.
D-MRI scans are natively in the DICOM or PACS medical imaging data formats. Which one was used depending entirely on the country the scanner was located in, as such the scan format is standardised for use as input in medical VR in this manner.

Augmented Life >> US Research Indicates Thousands are Using Pokemon Go Whilst Driving
It would seem that when mirror worlds combine with mobile phones, there is a very real problem that too many users don't understand that it is not always safe nor appropriate to access the mirror world. A study here looks at the incidence of driving with or near misses with pedestrians whilst playing Pokemon Go via social media in a ten day period, with alarming results.
Alternate Lives >> People conform to the norm – whether that norm is physical or virtual
Industry news, originally posted in January 2015, deemed too important to be allowed to fade. Often enough it is human nature to conform. This tendency makes us follow the lead of computers, even if the machines give us the wrong advice. This is the finding of a study in Springer’s journal Psychonomic Bulletin & Review that investigates how people make judgment calls after interacting within a virtual environment.
Augmenting Surgery >> Improving Robotic Surgery by integrating Augmented Reality Elements
Robotic surgical procedures are carried out with the aid of a camera system attached alongside the tools on the robotic arm that is inserted into the body of a patient. A surgeon carries out the operation by seeing through the camera's eye. As such, augmented reality systems have always seemed a good fit to overlay a virtual representation of the patient's innards, along with the full size and shape of the target area, on the display screen. However, the difficulty of AR object recognition inside the body has always proven too much of a hurdle. Until now.
Artificial Intelligence >> Simple Yet Highly Effective Robotic Boost to Mass Spectrometry
A group of biochemists at Georgia Tech had a dream; a dream of being able to automate the process of gathering samples for mass spectrometry. A dream whereby they could just hand the analysis tool a sample. It didn't matter what colour, shape, size, density, or anything it was. The tool would take over and just know how best to approach the problem of obtaining the sample. A nice pipe dream... until the College of Computing at the same university got wind of it.
Artificial Intelligence >> Robotic Insect: Guided by the Same stimuli
For an insect, it is rather large. Six inches in length, and rolling around on tank treds rather than walking. Yet, this German robot is the same as an insect where it counts - in the brain. It possesses an embodied needs-based AI, itself running on a simplified version of the insect brain, and responds to stimuli from the world around it in the self same way a natural insect would.
Artificial Muscles >> Artificial Muscle from Fishing Line: Powerful yet Cheap
When we think of artificial muscles, we tend to think of new materials that allow constructs to replicate the function of organic muscles in useful ways. We don't tend to think of existing materials in common usage as a means to create these muscles. After all if they are in common usage, they would already have been tested and discarded, right?
Embodied Avatars >> Futureworld
Futureworld is the sequel to Westworld, yet it takes an entirely different direction. Meant to be the film that spun the Westworld franchise into an anthology set, instead it was the film that buried it. Futureworld has some great ideas, and like many films of the era, is a goldmine of nuggets concerning robotic technology, virtual reality, augmented reality and social implications.
Pure Research >> Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos
Programming the Universe is a Simulation Argument book. Lloyd, a professor at MIT, works in the vanguard of research in quantum computing: using the quantum mechanical properties of atoms as a computer. He contends that the universe itself is one big quantum computer producing what we see around us, and ourselves, as it runs a cosmic program.
Pure Research >> Decoding Reality: The Universe as Quantum Information
Decoding Reality is very much a Simulation Argument book. In its pages, physicist Vlatko Vedral argues that we should regard the entire universe as a gigantic quantum computer.
Teaching and Training via VR >> Women and Gaming: The Sims and 21st Century Learning
Video games have become both big business and a technological focal point for new forms of learning. Today games are not just played; players engage in game design, write fan fiction, and organise themselves into collaborative learning communities. In these communities players acquire 21st century skills in technology, but, in the best of these communities, they hone these technical skills and strengthen emotional and social intelligence.
