How a PhD Student Unlocked 1 Bitcoin Hidden In DNA

dmoberhaus writes: A 26-year-old Belgian PhD student named Sander Wuytz recently solved a 3-year-old puzzle that had locked the private key to 1 Bitcoin in a strand of synthetic DNA. Motherboard spoke with the student about how they managed to crack the puzzle, just days before it was set to expire. From the report: “As detailed by Nick Goldman, a researcher at the European Bioinformatics Institute, in his pioneering Nature paper on DNA storage, to encode information into DNA you take a text or binary file and rewrite it in base-3 (so rather than just ones and zeroes, there are zeroes, ones, and twos). This is then used to encode the data in the building blocks of life, the four nucleobases cytosine, thymine, adenine and guanine. As Wuyts explained to me, coding the data as nucleobases depended upon which nucleobase came before. So, for instance, if the previous base was adenine and the next pieces of data is a 0, it is coded as cytosine. If the next piece of data is a 1, it’s coded as guanine, and so on. After the data is encoded as synthetic DNA fragments, these fragments are used to identify and read the actual files stored in the DNA. In the case of the Bitcoin challenge, there were a total of nine files contained in the DNA fragments. The files were encrypted with a keystream, which is a random series of characters that is included with the actual plain text message to obfuscate its meaning. The keystream code had been provided by Goldman in a document explaining the competition. After running the code, Wuyts was able to combine the DNA fragments in the correct order to form one long piece of DNA. After working out some technical kinks, Wuyts was able to convert the DNA sequence into plain text, revealing the private key and unlocking the bitcoin (as well as some artefacts, including a drawing of James Joyce and the logo for the European Bioinformatics Institute). He had cracked the puzzle just five days before it was set to expire.” Read more of this story at Slashdot.

Unexpected Viking toilet discovery leads to controversy

Museum Southeast Denmark Archaeologists excavating at an ancient Viking settlement in southeast Denmark thought they were dealing with a typical country town from the Middle Ages. Then a single toilet changed everything. Museum of Southeastern Denmark archaeology researcher Anna Beck was digging up what she thought was a semi-subterranean workshop, only to find that she was knee-deep in… yeah, you guessed it. She’d found a layer of medieval poop. Read 7 remaining paragraphs | Comments

Sunken British Submarine Found Off the Coast of Denmark

On April 10, 1940, British submarine HMS Tarpon and its crew of 50 were sent to Norway to intercept Nazi merchant vessels. They were was never heard from again. Now, after 76 years, the sub has finally been found. An investigation of the remarkably well preserved vessel shows it didn’t go down without a fight. Read more…

NYC’s New Public Wifi Is Obscenely Fast

Today, the first of New York City’s public, gigabit wifi hotspots opened to the public. I tried them, so take it from me: They’re insanely fast. How fast? Fast enough that Starbucks’ free internet is about to get killed. Read more…

Google And ASUS Launch The $85 Chromebit, A Chrome OS Desktop On An HDMI Stick

 Earlier this year, Google and ASUS announced the Chromebit — a full Chrome OS-based computer on an HDMI stick. Today, the two companies are officially launching this new way of using Chrome OS on any screen with an HDMI port. The $85 Chromebit is a 75 gram (or 2.6 ounces) stick that you can plug into any HDMI port — whether that’s a regular computer screen or that large TV… Read More

Archaeologists Baffled By 2,000 Tiny Gold Spirals Discovered In Denmark

Finding gold in Boeslunde, Denmark, is no huge surprise—it’s known as an area where Bronze Age gold offering are often uncovered, as curators there are explaining this month . But a recent discovery has surprised and baffled archaeologists: 2, 000 tiny gold spirals. It’s a “ golden enigma .” Read more…

Denmark Leads the Way Towards Ending Cash

Cash is expensive to manufacture. As we saw in our article on The U.S. Mint’s Production Materials Problem , a penny costs 2.4 cents to make, while a nickel costs more than double its actual value. But governments continue to manufacture physical currency because previously, that was the only way to enable commerce and hence, economic growth. Cash is also expensive (and time-consuming) to use. A 2013 Tufts University study found that using cash costs American citizens and businesses some $200 billion annually, which boils down to $1, 739 per household. And sadly, those costs are disproportionately borne by the poor. Theft ($40 billion from businesses and $500 million from individuals) and ATM fees of $8 billion make up a portion of these overall costs. But the majority of these costs come in terms of time: the average American spends 28 minutes per month traveling to get cash. It probably comes as no surprise that the cost of cash is higher for the poor and unbanked Americans. The unbanked pay on average about $3.66 per month more than banked consumers. Poor Americans carry larger amounts in cash and pay more fees for cash transactions than wealthier Americans. Those without bank accounts use greater amounts of cash in a month than those with bank accounts. One obvious solution would be to create affordable banking methods for the poor. Once we accomplish that, we can take the radical step that Denmark is taking: Ending cash, period.  The country has announced that next year they’ll stop printing the stuff altogether , meaning there’s going to be some sweet printing presses for sale on Danish eBay. And the Danish government has announced a new proposal that will allow merchants—gas stations, restaurants, clothing stores, et cetera—to refuse cash transactions. According to Reuters , a financial institution lobbyist says that “going cashless would save shops money on security and time on managing change from the cash register.” What this won’t end, of course, is theft; it will simply shift to a different arena, less ski-mask-and-gun, more keyboard-and-mouse. But if Denmark’s cashless society works on balance, it’s not inconceivable to think other countries will follow suit. As Fusion’s Kevin Roose puts it, “It’s time to take a lesson from the Danes…and admit that the 5, 000-year reign of physical currency has run its course.”

Denmark Plans To Be Coal-Free In 10 Years

merbs writes “Earlier this year, Denmark’s leadership announced that the nation would run entirely on renewable power by 2050. Wind, solar, and biomass would be ramped up while coal and gas are phased out. Now Denmark has gone even further, and plans to end coal by 2025. Read more of this story at Slashdot.

The World’s Fastest Network Lets You Download a Movie In .2 Milliseconds

Danish researchers just created the Usain Bolt of networks. A team from the Technical University of Denmark used a single multi-core optical fiber to transfer 43 terabits per second, making it the world’s fastest fiber network . I’d say it makes Google Fiber look like 1996 AOL dial-up from a decrepit rural phone line, but that comparison is too kind to Google Fiber. Read more…
