+Patrick Johnson You don't know who Elvis Presley is? or was?
Yeah, they had this big thing where he was sighted after his death. Stupid really. I guess you're too young to remember all that crap. So much the better.

Kinetic Sand an interactive table that responds to touch by creating plumes of sand that seem to whirl and dance around objects placed on top of it. The table is the latest creation from Adrien M / Claire B Company: http://www.am-cb.net/ This kinetic table accepts input from up to 32 simultaneous touches and responds by creating different kinds of animation using small dust-like particles.

+Toy LeChien I'd assume the same thing, although the continually moving spheres  make more interesting ever-changing patterns. A glass or remote might only have movement in the surface until it stops. Again just my speculation.

Glowing Millipedes

We all have our own different coping mechanisms when it comes to stress. A nice walk outside. A cold beer. A punching bag. Blowing up at your friends. And glowing in the dark. What? Scientists believe that these millipedes evolved to glow in the dark to deal with stress (and to let predators now that they’re packing toxic cyanide).

The millipede Motyxia sequoiae, which lives at the upper elevations of the Sierra Nevada, glows bluish green—a warning to predators that the arthropod contains toxic cyanide. All 11 species and subspecies in the genus Motyxia glow, but those at lower elevations of the mountains glow less brightly. Scientists now think the bioluminescence first evolved as a way for millipedes at lower elevations to cope with the stress of living in a hot, dry environment and later evolved into a warning signal as the species moved up the mountains.

+Mark Bruce selecting his best 10 for the past week, always excellent items to read here.
Mark Bruce originally shared to SciTech Digest:
 
SciTech #ScienceSunday Digest - 20/2015.
Permalink here: http://www.scitechdigest.net/2015/05/crispr-cancer-targets-sensory-cortex.html

CRISPR cancer targets, Sensory cortex organisation, Implantable drug factories, Prosthetics with sensation, Atomic switch networks, Antiaging cellular interventions, Making graphene composites, 3D printed engine, Regeneration and senescent cells, Structural colour. 

1. Identifying Anticancer Drug Targets with CRISPR
A new technique uses CRISPR technology to quickly and comprehensively identify specific vulnerabilities in cancer cells, across cell types http://www.cshl.edu/news-and-features/using-crispr-biologists-find-a-way-to-comprehensively-identify-anti-cancer-drug-targets.html. The proof-of-concept surveyed 200 possible possible targets in leukemia, successfully identified the 6 previously-known targets and verified an additional 19 new targets. This works by specifically mutating key regions of genes, nucleotide by nucleotide, that are involved in encoding functional binding pockets in proteins; if modification of a particular pocket causes the cancer cell to die then it becomes a candidate site to design a new drug against. This should lead to many more viable drug targets the development of therapeutics that were never considered; but I’d also like to see the tool used to identify other targets for other cellular modifications, e.g. cell senescence, stem cell proliferation and differentiation etc. 

2. New Organisational Principles of the Sensory Cortex
Custom-designed high-resolution 3D reconstruction and modelling techniques have provided incredible new insights into the interconnectedness of neurons within and across the fundamental processing units called neocortical columns http://www.maxplanckflorida.org/news-and-media/news/3d-reconstruction-of-neuronal-networks-provides-unprecedented-insight-into-organizational-principles-of-sensory-cortex/. Previously, the neuronal networks within cortical columns were thought to be the most important structural feature. This work shows that, instead, the majority of neuronal circuitry actually interconnects neurons across multiple cortical columns by following very specific principles. The group extend the concept of cortical columns to intracortical units, and proposes that these higher-order units integrate information across multiple stimuli to anticipate future, related, stimuli. 

3. Implantable Cellular Drug Factories
Bacteria genetically modified to (i) produce and secrete an enzyme that converts a harmless prodrug into a cytotoxic chemotherapy drug and (ii) control this production subject to temperature-dependent regulatory control, have been encapsulated in magnetic nanoporous capsules that prevent the cells from coming into contact with the immune system while still allowing the passage proteins and nutrients, and which are then implanted into animal tumours where the application of an alternating magnetic field causes the capsules to heat up and for the bacteria to then induce the localised production of cancer-killing therapeutic drugs http://cancer.dartmouth.edu/about_us/newsdetail/73456/. I wonder what we might do with systems like this that allow the localised or systemic controlled production of any protein or biomolecule of choice?

4. Prosthetic Limbs with a Sense of Touch
A new circular electrode designed to encase and stimulate nerves in the upper arm is being tested in non-human primates to determine what touch sensations can be induced and “felt” on the primate’s hand, how best to induce these sensations, how many sensors can be packed onto a prosthetic hand to provide as much sensation as possible, and how much bandwidth the brain is capable of taking in from the electrode array http://news.wustl.edu/news/Pages/device-may-allow-sensation-in-prosthetics.aspx. The mechanical sophistication and thought-control via brain-computer interfaces of prosthetic limbs have come a long way; the key missing component of sensory feedback has remained elusive however. 

5. Self-Organised Atomic Switch Networks
A new type of chip called an atomic switch network is fabricated by growing silver nanowires atop a patterned seed network of copper posts; the chaotic pattern of silver nanowires connect points where the nanowires touch and form memristor connections http://phys.org/news/2015-05-scientists-atomic-scale-hardware-natural.html. The research team believes the device demonstrates emergent behaviour and patterns of electrical activity that can only be attributable to the network as a whole, with the memristive connections and switches constantly reconfiguring and adapting to inputs. Whether such an architecture might ever perform useful computations is yet to be seen, although I’d love to see them scale the chip further and add extra layers of interconnections, moving from 2 to 3 dimensions and so becoming more brain-like. 

6. Sophisticated Cellular Interventions for Anti-Aging
A few studies this week showed how old cells might be taught young tricks again. First, leading on from parabiosis studies we have targeted knock-down of Transforming Growth Factor Beta successfully renewing stem cell function in both brain and muscle tissue of old mice and also, specifically showed that hippocampal stem cells became more youthful http://newscenter.berkeley.edu/2015/05/13/drug-perks-up-old-muscles-and-aging-brains/. Second, specific proteins isolated from stem cells were shown, when introduced to mice, to be sufficient for stimulating the growth of new bone http://gladstoneinstitutes.org/pressrelease/2015-05-11/scientists-regenerate-bone-tissue-using-only-proteins-secreted-by-stem-cells. Four, targeted disablement of telomeres in cancer cells http://www.eurekalert.org/pub_releases/2015-05/cndi-csa051115.php. Finally, we had a good review article on new ways to specifically stimulate the rejuvenation of muscle stem cells in older animals https://www.fightaging.org/archives/2015/05/considering-the-rejuvenation-of-muscle-satellite-cells.php

7. Large-Scale Fabrication of Graphene Composites
A new chemical vapor deposition technique allows the fabrication of multi-layered polymer graphene composite materials that, in the proof of concept, contains 2 inch square sheets of graphene http://www.ornl.gov/ornl/news/news-releases/2015/ornl-demonstrates-first-large-scale-graphene-fabrication?. This is apparently the first time graphene composites have been manufactured at this scale and enabling graphene’s amazing mechanical and electrical properties to be evidenced at the macroscale. In related news 3D printed graphene aerogels have interesting properties and applications https://www.llnl.gov/news/3d-printed-aerogels-improve-energy-storage

8. The Latest 3D Printed Jet Engine
GE demonstrated its completely 3D printed mini jet engine this week http://www.gereports.com/post/118394013625/these-engineers-3d-printed-a-mini-jet-engine-then. Their promotional video is worth a watch if you haven’t seen it already https://www.youtube.com/watch?v=W6A4-AKICQU. This functional little engine was successfully tested at 33,000 rpm after being printed via laser in a Direct Metal Laser Melting process built up from powdered metal and metal alloys. It’d be nice to see them test it in flight on a hobby aircraft, but there are no plans yet for a fully 3D printed commercial jet engine. 

9. Salamanders, Regeneration, and Senescent Cells
An interesting study exploring salamander limb regeneration reveals that this process involves a significant induction of cellular senescence followed by rapid and effective (immune) mechanisms for senescent cell clearance in both normal and regenerating tissues https://www.fightaging.org/archives/2015/05/an-intriguing-finding-on-senescent-cells-in-salamanders.php. Interfering with the immune system during regeneration results in defects in the process. The promise here is that further studies might reveal how the salamander immune system consistently targets and clears senescent cells and this mechanism might be replicated in humans as an anti-aging therapy to clear damaging senescent cells. 

10. Structural Nanomaterials for Structural Light
A new structural colour technology platform has been developed that involves the use of nanoparticles of polydopamine packed into solid layers on a thin film http://phys.org/news/2015-05-nanomaterials-bird-feathers.html. Inspired by the use of nanoparticles of melanin by some birds to produce colour, the thin films reflect pure colours of (so far) red, orange, yellow, and green light that are determined by the thickness and density of the film. Unlike colours or dyes based on pigments, materials exhibiting structural colour are not expected to fade with time.

Spaceplasma

The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the Ω-shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in Hα. EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIF show multiple energetic jets in three different wavelengths. The light has been colorized in red, green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.

Rocket-triggered lightning event

Because thunder and lightning are unpredictable, the phenomena are best studied using triggered events. The technique involves launching a small rocket trailing a grounded copper wire into thunderclouds. The copper wire provides a conductive channel and creates a predictable path for lightning, allowing scientists to precisely focus their instruments and perform repeatable experiments close to the discharge channel. Using SwRI internal research funding, Dr. Maher Dayeh led a proof-of-concept experiment to image the acoustic signature of thunder. SwRI conducted experiments at the International Center for Lightning Research and Testing at the University of Florida, Gainesville, taking advantage of the state’s claim to the most lightning strikes per year in the U.S.

To map the acoustic signatures of thunder, Dr. Maher Dayeh and his team set up an array of of fifteen microphones, a meter apart, spiraling outwards from the site of the triggered lightning strikes. Using a few different processing techniques and a focus on higher sound frequencies, Dayeh eventually uncovered a distinct thunder signature.

SwRI reveals the first “images” of thunder:

+Rich Pollett Thank you for the post and my humble apologies though if I may, a experience I had at high school in 1981 may explain myself.

I was in class and discussion of graphite as a conductor and how the search was on to get a thin layer.  Now I had a pencil and some cellotape and had a sliver of pencil lead I'd placed between cellotape and pulled apart making the layer thinner, which I repeated.  I said to the teacher that if you carried on then you would get a thin layer of graphite.  The teacher just laughed and in effect made me out to be an idiot for even thinking that would work and if it did it would of already of been done and proven to not work.  A general laugh and point moment at me.   

What could of been had the teacher been open mind and explained why and presumed nothing.  Is that what true science is.


As for Jim, he reminds me of my teacher as I expereinced him - https://plus.google.com/+FraserCain/posts/5wmJ4ovkio6

But I certainly wish him the best and just caught him on a off day.  Enough said.
