Dome installed over a new antenna at the Svalbard Satellite Station (photographer: Anna Filipova)

SvalSat, as the station is known, is a crucial, behind-the-scenes workhorse supporting scientific research. Located just outside the town of Longyearbyen in the Svalbard Archipelago, it is 800 miles from the North Pole, making it the northernmost satellite station in the world.

The experiences of the Umbrella Movement and recent clashes with police have taught protesters what equipment they need at the front lines. To ensure new supplies can reach the front lines quickly, Hong Kong’s protesters have developed a unique system of hand signals, to send messages through the crowd about what equipment is required. 

A sign is passed onwards through the crowd back to the supply depots where goods have been transported near to the protest site, and the requested items are then passed through the crowd along a human chain back to where they are needed. These human supply chains have stretched as far as a kilometre in length, and are an impressive sight to behold.

“[in 1977] NASA launched Voyager 1, the second of two spacecraft on a grand tour of the solar system and into the mysteries of interstellar space. Attached to each spacecraft is a Golden Record containing Earth’s greatest music, spoken greetings, “Sounds of Earth,” and more than 100 images encoded as audio signals, a technological feat at the time. Technical director Frank Drake had always planned to encode the photos in the audio spectrum for the record. The challenge was finding technology capable of the task. While flipping through an electronics catalog, Valentin Boriakoff, Drake’s colleague at the National Astronomy and Ionosphere Center, stumbled upon Colorado Video, a small television equipment firm in Boulder that had built a unique device for encoding television images as audio signals that could be transmitted over telephone lines. Donating their time and expertise to the project, engineers at Colorado Video projected each Voyager slide onto a television camera lens, generating a signal that their machine converted into several seconds of sound per photo. A diagram on the aluminum cover of the Golden Record explains how to play it and decode the images. Four decades later, Ron Barry followed the instructions.”

The Great Silence by Ted Chiang

Medium, ted chiang, non-human, communication, other, parrots, interspecies communication, SETI, STI, Fermi Paradox, The Great Silence

Ted Chiang’s very short story, “The Great Silence” adds another set of questions to these speculations. Why, he asks, are we so interested in finding intelligence in the stars and so deaf to the many species who manifest it here on earth? And also: why have we demanded that, as proof of intelligence, non-human animals communicate to us in human language, and then dismissed those creatures that actually do so?

The Future Is A Confidence Trick

prediction, futures, social fabric, telegrams, communication, Warren Ellis

Prediction is an industry, and its product is a persuasive set of hopes and fears that we’re trained or convinced to agree upon. It’s a confidence trick. And its product comes so thick and fast that, like a plothole in an action movie, we’re carried on past the obvious failures and the things that didn’t even make sense if we had more than five seconds to think about them.

Submarine Cable Taps

Documents published on November 25, 2014 by Süddeutsche Zeitung revealed more specific details about submarine cables currently tapped by GCHQ. Previous reporting had made it clear that GCHQ had submarine cable taps created in collusion with companies like Vodafone and BT Cable, but not which specific cables. Seeing Telegeography publishes landing point maps and submarine cable maps it seemed like a worthwhile exercise to better understand what, exactly, the reach of GCHQ’s submarine cable tapping might look like.

RNA trafficking in parasitic plant systems

plants, communication, botany, patabotany, mRNA, RNA trafficking

Certain parasitic plant species form symplastic connections to their hosts and thereby provide an additional system for studying RNA trafficking. The haustorial connections of Cuscuta and Phelipanche species are similar to graft junctions in that they are able to transmit mRNAs, viral RNAs, siRNAs, and proteins from the host plants to the parasite. In contrast to other graft systems, these parasites form connections with host species that span a wide phylogenetic range, such that a high degree of nucleotide sequence divergence may exist between host and parasites and allow confident identification of most host RNAs in the parasite system.

A Rant about ‘Ragnarok 2014’

Ragnarok, publicity, communication, mythology

But Ragnarok is not a joke. It’s a story of terrible fear, annihilation, though with a hope of rebirth. The dread of it runs through many stories in Norse myth - the knowledge that for the gods this destruction will come, inevitably and irrevocably. In Snorri’s Edda, the story is also deeply sad: Ragnarok begins with a family grieving helplessly for their dead son. (Couldn’t fit that in the press release, I guess.) Can we not take that seriously? If nothing else, can we not maintain a basic level of respect for a belief system different from our own? How can we ever hope to understand the Vikings, or any past society, if we turn their mythology into a joke?

Hillbilly Tracking of Low Earth Orbit Satellites

satellite, communication, networks, tracking, DIY, Travis Goodspeed

In this article, I’ll demonstrate a method for modifying a naval telecommunications dish to track moving targets in the sky, such as those in Low Earth Orbit. My dish happily sits in Tennessee, while I direct it using my laptop or cellphone here in Europe. It can also run unattended, tracking moving targets and looking for downlink channels.

On the Empire of the Ants

ants, communication, language, science

Science is an exercise in curiosity about nature. It is a process. It sometimes involves complex and costly apparatus, or the resources of giant institutes. Sometimes it involves looking at ants in an ant farm, and knowing some clever math. Many people are gobsmacked by the technological gizmos used to do science. They think the giant S&M dungeons of tokomaks and synchro-cyclotrons are science. Those aren’t science; they’re tools. The end product; the insights into nature -that is what is important. Professors Ryabko and Reznikova did something a kid could understand the implications of, but no kid could actually do. The fact that they did it at all indicates they have the child-like curiosity and love for nature that is the true spirit of scientific enquiry.

First Steps Toward Learning the Language of Mycorrhizal Communication

mycorrhizae, communication, plants, signaling, biochemistry

It has been hypothesized that both fungi and bacteria interacting with plant roots do so using similar genetic mechanisms. It has already been shown that rhizobial bacteria – particularly the nitrogen fixing microbes associated with leguminous plants – produce lipochitooligosaccharide (LCO) signals used in the communication with host plants. The authors of this study discovered that the fungus Glomus intraradices, like the nitrogen-fixing bacteria, secretes an array of sulfated and non-sulfated simple LCOs which stimulated the formation of arbuscular mycorrhizae in disparately related plants, such as Medicago (Fabaceae), Daucus carota (Wild Carrot; Apiaceae), and Tagetes patula (French Marigold; Asteraceae). These compounds were found in Glomus intraradices both interacting with plant roots and in free-living resting spores in the soil.

Two sciences separated by a common language

language, jargon, communication, boundaries, interdiscipline

One thing that gets in the way of this communication is jargon. Jargon is shorthand that helps people in a field communicate with each other. Needless to say, it can be a huge problem when communicating with the public. But jargon can also be a problem when you’re talking to other scientists. Not only is some of this niche speak meaningless outside its specific field, but in other fields it can sometimes mean something else entirely.

Photography’s Third Act

photography, dustin curtis, communication, experimentation, art, documentation, photos, treehouse, n

When personal photography was first becoming popular, it was mostly used for experimentation and artistic expression, like portraiture. Over time, as costs decreased and fidelity increased, photos gained a second function: they became a system for people to store their memories. And only very recently have we begun to experience the third major function of photography, and I think it’s far more important than the other two: photos for individual communication.

Immaculate Telegraphy

Immaculate Telegraphy was an experiment to build electronic communication from scratch in the wilderness. In summer of 2009, I set out in the mountains of western Montana without any modern tools or materials except information, and constructed a working electric telegraph from materials found on the ground. The experiment showed that electronic communication could have been constructed at any point in history given the right information.

Google Engineer Told Others of Data Collection

technocracy, communication, corporatism, privacy, google

Google’s harvesting of e-mails, passwords and other sensitive personal information from unsuspecting households in the United States and around the world was neither a mistake nor the work of a rogue engineer, as the company long maintained, but a program that supervisors knew about, according to new details from the full text of a regulatory report. The report, prepared by the Federal Communications Commission after a 17-month investigation of Google’s Street View project, was released, heavily redacted, two weeks ago. Although it found that Google had not violated any laws, the agency said Google had obstructed the inquiry and fined the company $25,000. On Saturday, Google released a version of the report with only employees’ names redacted.
