Social Presence: Volume, Variety, Velocity and Veracity

"Google and its semantic search algorithms, once they're fully understood as more than the sum total of our dialogic intentions, will save the world."
-- +John Kellden 

"Semantic enrichment via analogy is what justifies the use of a single word or phrase as a label of more than one category allowing us to glide smoothly up or down a spectrum of abstraction choosing the appropriate point along the way as a function of the context in which we find ourselves."
-- Douglas Hofstadter, Surfaces and Essences

"The semantic web is driven by Big Data attributes: Volume, Variety, Velocity and Veracity and in the very last of these, by degrees, we are being forced to become less deceitful. Veracity is a complex calculable attribute that demands nothing less than total transparency and sustained consistency to even begin to work. These can only be achieved when we are as open and authentic as possible, otherwise inconsistencies creep in and we get the exact opposite effect."

Semantic SEO Questions
Finally semantic search is beginning to make its effects felt sufficiently for the questions to start being asked.  +David Bürge shared a great find. 

Over the past month or so I have been on a number of HOAs covering some specific aspects of semantic search and working in the semantic web: 

+Kathi Browne  - just this week posed some very interesting questions regarding the Healthcare Industry and semantic search in general - http://goo.gl/FvkiX

+Luis Galarza  - Has an entire resource page set up on semantic SEO for small businesses that should definitely be bookmarked: http://goo.gl/yRSFs

I had a brilliant HOA with +Yifat Cohen  where we covered some aspects of the semantic web - http://goo.gl/L2KbQ

Semantics - a very important issue in terms of search queries, result pages and required quality content to achieve high relevance for optimiezed topics. It is no longer sufficient to optimize only specific keywords.

SciTech #ScienceSunday Digest - 07/2015.
Permalink here: http://www.scitechdigest.net/2015/02/crispr-via-light-volume-graphene.html

CRISPR via light, Volume graphene production, Spot the robot, Printed DNA hydrogels, Implanted artificial organs, Printing via spinnerets, Scanadu tricorder, Prosthetic arms, Contact lens telescope, GMO apple approval. 

1. Light-Induced CRISPR for Custom Tissue Architectures 
By attaching light sensitive proteins from plants to a specific CRISPR sequence and to gene activation proteins a new controlled gene regulation system has been engineered that enables any desired gene to be switched on and off by simply shining light of a particular wavelength onto the cell http://www.pratt.duke.edu/news/controlling-genes-light. The proof-of-concept showed a dish of cells expressing fluorescent proteins only on those areas that had been exposed to light. Future applications include light-induced control over the variable differentiation of stem cell cultures to facilitate better and more realistic tissue engineering, or even skin-based cell therapies that allow you to activate a particular pathway at will.

2. Towards Volume Production of Graphene
An alteration to conventional chemical vapour deposition techniques has resulted in a new method to enable the scalable production of graphene sheets http://www.rug.nl/news/2015/02/0210-publ-grafeen. The key insight was simply to grow the graphene on a copper oxide substrate; the process of removing or decoupling the graphene from this substrate preserves the graphene structure and properties and circumvents the risks of breakage or contamination. In related graphene fabrication news, 3D printing of complex 3D graphene-based structures is being facilitated by better graphene-loaded inks http://www.nanowerk.com/spotlight/spotid=38965.php

3. Spot, by Boston Dynamics
Leading robotics company Boston Dynamics showed off a new mid-size quadruped robot weighing 160 lbs called Spot this week http://spectrum.ieee.org/automaton/robotics/robotics-hardware/spot-is-boston-dynamics-nimble-new-quadruped-robot. Smaller but faster and more agile than its big brother Big Dog, Spot is battery powered and actuated by hydraulics, and can recover quickly from even severe knocks - as can be seen in the embedded video and which will test your anthropomorphic tendencies. In other robotics news new flying drone designs prove almost indestructible in most situations http://spectrum.ieee.org/automaton/robotics/aerial-robots/gimball-drones-for-good-competition

4. 3D Printed Self-Assembled Hydrogel Structures
Complementary DNA strands loaded into a gel enable the gel to carry live cells and be 3D printed into custom structures http://phys.org/news/2015-02-synthetic-dna-gel-artificial.html. The complementary DNA self-assembles to impart the mechanical characteristics of the gel, which can be altered as needed by changing the sequence of DNA; this self-assembly obviates the need for high temperatures and so better facilitates the handling of live cells through a print nozzle for tissue engineering applications. In other biological self-assembly news the self-assembled protein coats some microbes use to protect themselves is offering insights for engineering artificial variants for a range of purposes http://newscenter.lbl.gov/2015/02/11/bacterial-armor/

5. Artificial Organs in Implantable Capsules
Pancreatic precursor cells loaded into a flexible, biocompatible mesh capsule that blocks white blood cells but allows the passage of nutrients, oxygen, waste products, proteins, and secreted factors, successfully treats diabetes in animals for long periods of time and has already been implanted into one person to kick off clinical trials http://www.technologyreview.com/news/535036/a-pancreas-in-a-capsule/. The device was developed by Viacyte and they aren’t the only group developing similar technologies; future work will improve the life of the device and create full differentiated islet cells rather than a mix. It’s fascinating to think how the function of artificial organs can be provided in this way, or even other custom biological functions perhaps; combined with the light-induced CRISPR you could have a subdermal patch that you switch on when needed to pump out some enzyme like alcohol dehydrogenase for example. 

6. Robotic Bio-Mimicking Spinnerets for Amazing 3D Printing
A new 3D printer demonstration combines a robotic arm and an innovative 3D printer that includes multiple dynamically moving print heads that each continuously extrude print filament in a system that mimics a spider’s spinnerets extruding silk fibres http://gizmodo.com/this-incredible-robotic-arm-prints-plastic-like-a-spide-1685397572. The machine can extrude or “print” custom 3D fibres or structures, suspended in space, on the go and results in fibres comprising an internal core fibre surrounded by three looping fibres that help convey structural strength and flexibility. Check out the video; it’s pretty amazing. Think of this attached to a mobile robot or mobile swarm of robots. 

7. Scanadu Personal Medical “Tricorder” Ships
Starting out as a successful Indiegogo crowd-funding project Scanadu has finally launched and shipped their Scout product, a small round device that is held to the forehead and very quickly sends readings to your smartphone with measurements of heart rate, temperature, blood pressure, oxygen level, and ECG http://edition.cnn.com/2015/02/12/tech/mci-scanadu-tricorder/index.html?eref=edition. Early users will help with real world calibration and testing and if the measurements are confirmed as accurate (an FDA submission is also in the works) then this would be a pretty powerful consumer device and one I’d definitely buy. They are also working on a “Scanaflo” product, intended to be a urine test kit for measuring  wide range of metabolic factors.

8. Prosthetic Arms by DARPA & OSRF
DARPA and its partners including the Open Source Robotics Foundation continue to develop advanced prosthetic arms and hands for amputees http://spectrum.ieee.org/automaton/robotics/medical-robots/darpa-and-osrf-developing-nextgen-prosthetic-limbs-in-simulation-and-reality. In a couple of recent demonstrations of the ongoing work we can see a man using a prosthetic arm to climb a rock wall, while other amputees use the prosthetic arms to pick grapes, spoon-feed themselves, “hand” objects between each other, pour drinks into glasses and other feats. The ultimate goal of the program is to create artificial limbs that behave like, are controlled like, and for the user feel like, a normal biological arm. 

9. Telescope in a Contact Lens
Another DARPA collaboration, this time with the EPFL, has resulted in the production of a new type of contact lens embedded with thin aluminium mirrors that, in conjunction with a pair of LCD glasses function as a telescopic lens http://gizmodo.com/this-contact-lens-can-zoom-in-with-a-wink-of-the-eye-1685695869. Light passing through the LCD in one polarisation appears normal and conveys normal vision, but switch the LCD to produce a different polarisation that interacts with the contact lens and the result is telescopic magnification. Future work will improve the oxygen permeability of the lens for greater eye comfort and perhaps seek incorporate the switchable liquid crystal elements directly. 

10. Genetically Modified Apples Approved by Regulators
For the first time genetically engineered apples have been granted regulatory approval by the US Department of Agriculture http://www.theverge.com/2015/2/13/8035775/gmo-apples-usda-commercial-farming-genetically-modified. The genetic modifications are pretty simple, and involve altering the activity levels of a particular gene / enzyme to ensure the apples will greatly resist browning when cut or dropped. I can only hope that this paves the way for greater varieties and greater numbers of different GM foods that convey a range of different nutritional benefits such as more vitamins, etc as opposed to the usual pesticide resistance that we usually see with staple crops.

The term Wi-Fi, commercially used at least as early as August 1999, was coined by a brand-consulting firm called Interbrand Corporation. The Wi-Fi Alliance had hired Interbrand to determine a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'". Phil Belanger, a founding member of the Wi-Fi Alliance who presided over the selection of the name "Wi-Fi", also stated that Interbrand invented Wi-Fi as a play on words with Hi-Fi, and also created the Wi-Fi logo

The Wi-Fi Alliance used the "nonsense" advertising slogan "The Standard for Wireless Fidelity" for a short time after the brand name was invented, leading to the misconception that Wi-Fi was an abbreviation of "Wireless Fidelity"
