I backed on Kickstarter this beautiful vintage map of the Mandelbrot set.
Meticulously researched and compiled, this poster functions as a thought-provoking guide to the astonishingly complex Mandelbrot set.

" Click-through data has proven to be a critical resource for improving search ranking quality. Though a large amount of click data can be easily collected by search engines, various biases make it difficult to fully leverage this type of data. In the past, many click models have been proposed and successfully used to estimate the relevance for individual query-document pairs in the context of web search. These click models typically require a large quantity of clicks for each individual pair and this makes them difficult to apply in systems where click data is highly sparse due to personalized corpora and information needs, e.g., personal search. In this paper, we study the problem of how to leverage sparse click data in personal search and introduce a novel selection bias problem and address it in the learning-to-rank framework."

Beautiful map/image/poster/wallpaper.
 
 
billtavis: I just completed the finishing touches on my new poster, a detailed map of the Mandelbrot Set in a vintage style. I’m calling it the Mandelmap. The Mandelbrot Set is a fractal shape with infinite detail that you can zoom in on. I often explore the Mandelbrot Set to find trippy patterns to create gifs with, but when I started I felt like I was just poking around at random. So I wanted to create a printed guide for myself to fin...

SciTech #ScienceSunday Digest - 17/2016.
Permalink here: http://www.scitechdigest.net/2016/04/engineered-artificial-ribosomes.html

Engineered artificial ribosomes, Tantalising EmDrive, Nanomagnet Holograph displays, Hafnium oxide memristors, Rejuvenation genetherapy confirmed, Improved CRISPR, Seawater uranium extraction, Implantable ultrasound communications, Biomimicry brighter LEDs, Actin memory role.

1. Artificial Synthetic Ribosome
Ribosomes in cells take in genetic code and sequentially synthesise a complete protein from specific amino acids that correspond to that code. A new, autonomous molecular machine based DNA has been developed as an artificial synthetic ribosome able to take specific sequence instructions and make new synthetic polymer materials out of different molecules in a similar way http://www.rsc.org/chemistryworld/2016/04/ribosome-mimic-dna-molecular-machine-polymer-production. The full paper is also worth a look http://sci-hub.io/10.1038/nchem.2495. The system relies on (i) chemistry DNA hairpin sequences attached to specific reactant molecules, and (ii) instruction DNA hairpin molecules with sequences that control the order in which the different monomer reactant molecules are assembled. Autonomous, programmable, atomically precise synthesis of large molecules. In related news another engineered ribosome functions in bacteria to create proteins with beta-amino acids that has never been achieved in live cells before http://news.yale.edu/2016/04/21/new-protein-making-factory-promises-better-medicines.

2. EmDrive and Unruh Radiation
To date six independent experiments have replicated the original EmDrive results by building their own device and measuring a thrust from a hollow cone when microwaves are bounced inside it, all without a suitable explanation for a seeming violation of conservation of momentum. A new theory of inertia suggests inertia is the pressure Unruh radiation exerts on an accelerating body, an effect predicted by General Relativity, and which also explains the acceleration discrepanies in falyby anomalies https://www.technologyreview.com/s/601299/the-curious-link-between-the-fly-by-anomaly-and-the-impossible-emdrive-thruster/. The theory suggests inertia is quantised, predicts flyby anomalies and their discrepancy, predicts the magnitude of thrusts measured in all experiments done so far, and makes two predictions yet to be tested: (i) a dielectric in the cavity will enhance thrust, and (ii) changing cavity dimensions will reverse thrust. It also assumes photons have inertial mass and the speed of light changes in the cavity. Will be interesting to see where this goes.

3. Nanomagnet Pixels for Holographic Displays
Wide-angle 3D holographic displays have been developed that are powered by nanomagnets http://www.eurekalert.org/pub_releases/2016-04/tuot-npt041916.php. The nanomagnets in these displays are referred to as magneto-optic spatial light modulators; a laser focused on the surface defines the display pixel size, pixel switching occurs in 10 nanoseconds, with pixel size and pitch in this demonstration being 1 micrometer, and enabling a 30 degree viewing angle. A nice advance in spatial light modulators towards the goal of glasses-free holographic video displays.

4. Hafnium Oxide Memristors as Synapses
New memristors made of thin-film hafnium oxide and via conventional production processes show promise as artificial synapses in brain-like chips http://phys.org/news/2016-04-physicists-electronic-synapses-neural-networks.html. Demonstrations show the memristors reproducing electrical signalling behaviour as observed in biological synapses, including spike-timing-dependent plasticity, long-term potentiation, and long-term depression. Next step will be to incorporate these hardware prototypes into larger brain-like chips.

5. Rejuvenation Gene Therapy Confirmed Against Aging
BioViva has confirmed Liz Parish’s experimental gene therapy, undertaken last year for disabling myostatin and extending teleomeres, successfully extended the telomeres of the cells that were analysed (white blood cells) from 6.71kb to 7.33kb and so effectively removing an average of 20 years worth of telomere shortening http://bioviva-science.com/2016/04/21/first-gene-therapy-successful-against-human-aging/. As always an N=1 should be taken with a grain of salt; the company has received an injection of funding and repeatability will be key in convincing skeptics of the result. The same techniques could be used to target the Per2 gene, leading to rejuvenation of the mammalian immune system and prolonged lifespans http://www.alphagalileo.org/ViewItem.aspx?ItemId=163209&CultureCode=en.

6. Single DNA Base Read/Writes Via CRISPR
A newly developed version of CRISPR can be targeted to specific sites in the genome and instead of cutting the DNA, precisely change one DNA base for another in order to correct precise single-base mutations or misspellings https://www.statnews.com/2016/04/20/clever-crispr-advance-unveiled/. This again reduces the risk of off-site target effects and provides an elegant way to make edits, provided the group can further improve the tool to be capable of all 12 basepair swaps (currently does 2). A protein nanopore array has been used for real-time single-base electronic DNA sequencing http://www.eurekalert.org/pub_releases/2016-04/cuso-cet042116.php. The nanopores incorporate a DNA polymerase protein that synthesises a complementary DNA strand as the strand of interest is passed through the pore; each of the four different nucleotides added incorporates a distinct tag that facilitates clearer and more accurate electrical signals that allow the sequence to be reconstructed.

7. Improvements in Extracting Uranium from Seawater
There are lots of efforts to extract useful elements from seawater with Uranium being of particular interest given the oceans collectively hold 4 billion tons of Uranium. Significant advances are being made with seawater extraction of Uranium via novel adsorbent materials that can now achieve 5.2 grams of Uranium per kilogram of adsorbent after 49 days in seawater, and with more recent tests showing 6 grams after 56 days https://www.ornl.gov/news/advances-extracting-uranium-seawater-announced-special-issue. There would be many benefits to achieving economical Uranium (and other metals) extraction from seawater.

8. Ultrasonic Data Transmission Through Flesh
Ultrasonic signals can now be used to transmit data through meat at 30 mbps, enough for HD video http://spectrum.ieee.org/tech-talk/biomedical/devices/ultrasonic-signals-transmit-data-through-meat-at-hd-video-quality. Current implanted medical devices are usually limited to much lower data rates, but having wireless data transmission via ultrasound able to deliver HD video offers a number of benefits including live-streaming video from swallowed camera-pills, easily managing large firmware updates to implanted devices, and others. Next step is animal studies and confirmation of the effect of bone structures on data rates.

9. Biomimicry for Brighter LEDs
The amount of light emitted by LEDs was boosted by 60% by carefully shaping the outer surface of the LED to mimic the structure of a firefly’s lantern http://gizmodo.com/scientists-made-leds-60-percent-brighter-by-copying-fir-1771979185. This essentially amounts to forming a nanostructured lens on top of the LED and these structures reduce the difference in refractive index between the material body and air, allowing more light to be emitted. This opens up the possibility for more power-efficient LEDs, but I’m also wondering if they can flip it and improve the efficiency of photodetectors and photovoltaics?

10. The Role of Actin in Memory
New models suggest that actin, the protein that helps to control cell shape, is responsible for the formation of long-term memories http://news.rice.edu/2016/04/18/thanks-actin-for-the-memories/. This concerns studies of the energy landscape of proteins and how actin filaments pull upon and stabilise certain proteins to form longer, more stable, and insoluble prion-like fibers. This offers another piece of evidence for the biological role of prion-like proteins, and also suggests a healthy role for some types of protein aggregates in cells, which are often considered a sign of disease and malfunction. This provides a mechanism for synaptic structures to last many years, if not decades, although the transition from short-term memory to this form of long-term memory is not yet known.

Story

Atypical search marketeer. I optimize stuff.
Introduction
I'm a search marketing consultant, I develop custom SEM strategies for high-profile companies, new methodologies and assistive software for SEOs.

On Google+ I mostly share and create contents related to marketing but, especially during the weekends, I'll share also posts about sciencenerd things and art (which includes narrative-focused video games).

You can read a glimpse of my most peculiar SEO posts visiting my "Insightful SEO stuff" collection of posts.

My approach to search marketing and SEO is partly science-based: while information retrieval, database design, statistics and math do not always have a direct effect on my daily SEO activities, this knowledge helps me to distinguish between flawed SEO theories/statements and good SEO information. It also helps me to foresee where search marketing is headed to and how things will change over time.

I publish my SEO articles, analyses, insights and detailed explanations on my personal blog (in Italian): LowLevel.it
