How a Bitcoin Transaction Actually Works

At this point, you probably have a working understanding of what bitcoins are (at the very least your handle of bitcoins is like how you can kinda, sorta explain why the sky is blue to a kid). But how does an actual transaction with bitcoins work? That’s a bit more complicated. It’s not exactly pulling crumpled cash out your pocket and dropping it off at the bodega counter for a soda now is it? Read more…

US Government Monitoring Associated Press Phone Records

Picass0 writes with distressing news from the AP wire, about the AP: “The Justice Department secretly obtained two months of telephone records of reporters and editors for The Associated Press in what the news cooperative’s top executive called a ‘massive and unprecedented intrusion’ into how news organizations gather the news.” They obtained call records from a number of desk phones, and the personal phones of many news editors. The DOJ has not commented, but it may be related to the possibility that the CIA director leaked information on a foiled terror plot in Yemen last year. Read more of this story at Slashdot.

Carnivorous Plant Ejects Junk DNA

sciencehabit writes “The carnivorous humped bladderwort, found on all continents except Antarctica, is a model of ruthless genetic efficiency. Only 3% of this aquatic plant’s DNA is not part of a known gene, new research shows. In contrast, only 2% of human DNA is part of a gene. The bladderwort, named for its water-filled bladders that suck in unsuspecting prey, is a relative of the tomato. The finding overturns the notion that this repetitive, non-coding DNA, popularly called ‘junk’ DNA, is necessary for life.” Read more of this story at Slashdot.

First vatburger is ready to eat

After spending $250,000 worth of anonymously donated money, Mark Post from Maastricht University is ready to go public with his first vat-grown hamburger, which will be cooked and eaten at an event in London this week. Though they claim that it’s healthier than regular meat, one question not answered in the article is the Omega 3/6 balance — crappy, corn-fed, factory-farmed meet is full of Omega 6s and avoided by many eaters; the grass-fed, free-range stuff is higher in Omega 3s. Yet growing meat in the laboratory has proved difficult and devilishly expensive. Dr. Post, who knows as much about the subject as anybody, has repeatedly postponed the hamburger cook-off, which was originally expected to take place in November. His burger consists of about 20,000 thin strips of cultured muscle tissue. Dr. Post, who has conducted some informal taste tests, said that even without any fat, the tissue “tastes reasonably good.” For the London event he plans to add only salt and pepper. But the meat is produced with materials — including fetal calf serum, used as a medium in which to grow the cells — that eventually would have to be replaced by similar materials of non-animal origin. And the burger was created at phenomenal cost — 250,000 euros, or about $325,000, provided by a donor who so far has remained anonymous. Large-scale manufacturing of cultured meat that could sit side-by-side with conventional meat in a supermarket and compete with it in price is at the very least a long way off.“This is still an early-stage technology,” said Neil Stephens, a social scientist at Cardiff University in Wales who has long studied the development of what is also sometimes referred to as “shmeat.” “There’s still a huge number of things they need to learn.” There are also questions of safety — though Dr. Post and others say cultured meat should be as safe as, or safer than, conventional meat, and might even be made to be healthier — and of the consumer appeal of a product that may bear little resemblance to a thick, juicy steak.

UK’s 4G Network Selling Subscriber Tracking Data To Police, Private Parties

Sockatume writes “The Sunday Times has revealed that analytics firm Ipsos MORI and 4G network EE attempted to sell detailed information on 27m subscribers’ activities to various parties including the UK’s police forces. The data encompasses the gender, postcode and age of subscribers, the sites they visit and times they are visited, and the places and times of calls and text messages. Ipsos MORI were reportedly ‘bragging that the data can be used to track people and their location in real time to within 100 meters’ in negotiations. Ipsos MORI has rushed to contradict this in an effort to save face, stating that the users are anonymized and data is aggregated into groups of 50 or more, while location is only precise to 700m. Despite their prior enthusiasm, the police have indicated that they will no longer go ahead with the deal. It is not clear whether the other sales will go ahead.” Read more of this story at Slashdot.

Sony reveals prototype 13.3-inch e-ink slate with stylus, aims to put it in students’ bags

Sony’s no stranger to the odd e-ink device , but its latest prototype creation isn’t targeted at the bookworm, it’s intended to educate. The e-paper slate is quite a lot bigger than most tablets, let alone e-readers, sporting a 13.3-inch screen (1,200 x 1,600) to match the standard A4 size of normal, boring paper. That display is also an electromagnetic induction touchscreen for poking at menus and scrolling, but more importantly, it supports stylus input for scrawling notes and annotating PDFs (the only file format it currently supports). The prototype device is also only 6.8mm (0.27 inch) thick and weighs 385g (13.6 ounces) — perfect for slipping into school bags. There’s 4GB of on-board storage (with a microSD slot to increase that) and WiFi, which Sony plans to use for sharing notes with those who didn’t make it to class on time. With WiFi off, the rechargeable battery inside is expected to last for three weeks of solid learning. These specs are for the prototype, of course, so after the late-2013 field trials at three Japanese universities, we might see some revisions before commercialization goes ahead sometime during the 2013 fiscal year.
