HughPickens.com writes: Ben Popper writes at The Verge that bitcoin's nightmare scenario has come to pass as the bitcoin network reached its capacity, causing transactions around the world to be massively delayed, and in some cases to fail completely. The average time to confirm a transaction has ballooned from 10 minutes to 43 minutes. Users are left confused and shops that once accepted Bitcoin are dropping out. For those who want the Bitcoin system to continue to grow and thrive, this is troubling. Merchants can't rely on digital transactions that can take minutes or hours to validate. A number of prominent voices in the Bitcoin community have been warning over the past year that the system needed to make fundamental changes to its core software code to avoid being overwhelmed by the continued growth of Bitcoin transactions. A schism has developed between the team in charge of the original codebase for Bitcoin, known as Core, and a rival faction pushing its own version of that open source code with a block size increase added in, known as Classic. "Many in the US Bitcoin community had hoped that hitting this crisis point — a network maxed out, transactions faltering — would result in closure, with miners quickly moving to adopt whichever chain proved more valuable to their economic interests," says Popper. "But so far the debate is dragging on without one side claiming a clear victory, leaving tens of thousands of consumer transactions stranded in limbo."

Deathspawner writes: Last March, Canada's regulatory agency for all things broadcasting, CRTC, ruled that cable TV providers would soon be forced to offer $25/mo packages. With enforcement having kicked-off on March 1, these inexpensive packages have now been made available. As Techgage has discovered, though, the first packages out-of-the-gate pack a number of caveats, and in some cases, are outright misleading. And, despite a simple framework to worth with, the two largest providers in the country, Rogers and Bell, offer vastly different packages, and ultimately vastly different values to the consumer.

sciencehabit writes: In a new study, researchers led by Edward Chuong, a computational biologist at the University of Utah in Salt Lake City, explored whether endogenous retroviruses (ERVs) help us fend off invaders. The scientists scanned three different human cell lines for ERVs in their DNA that could bind to innate immunity transcription factors, which turn on genes to ramp up the immune system's attack against pathogens. They found thousands of ERVs. The researchers predicted that if they remove this viral DNA from the cell, the transcription factors would not function properly, potentially disrupting genes involved in the innate immune response. Using the gene-editing tool CRISPR, they snipped out several endogenous viruses from the cell's DNA. When researchers infected these ERV-depleted cells with the vaccinia virus, they found a much weaker innate immune response that unedited normal cells, the team reports online today in Science. A key immune protein wasn't produced and thus was not fighting the virus. When researchers later added the genes back into the cells experimentally, immune function was restored. This new research provides evidence that "an ancient viral element is assisting us against an infection," Chuong says.

An anonymous reader writes: IBM is pushing big internet companies to pay patent licensing fees in part because IBM invented the Prodigy service, a precursor to the modern web. Yesterday, Big Blue filed a lawsuit against Groupon, saying the company has infringed four IBM patents, including patents 5,796,967 and 7,072,849. IBM inventors working on Prodigy "developed novel methods for presenting applications and advertisements," and "the technological innovations embodied in these patents are fundamental to the efficient communication of internet content," according to the company. The Prodigy patents were filed in 1993 and 1996, but they have "priority dates" stretching back to 1988. "Despite IBM's repeated attempts to negotiate, Groupon refuses to take a license but continues to use IBM's property," IBM lawyers write. IBM says it informed Groupon that it was infringing the '967, '849, and '346 patents as early as 2011. As for the '601 patent, IBM says that Groupon should have been on notice of that once Priceline got sued last year.

Lucas123 writes: By 2020, surgical robotics sales are expected to almost double to $6.4 billion, at the same time robots are becoming easier to use. One new robot is so easy to use that even med students can achieve proficiency with a few tries, according to Umamaheswar Duvvuri, director of head and neck surgery at the University of Pittsburgh Medical Center. The robot, a snake-like endoscope that can be directed into any shape through the relative orientations of its linkages, requires only one incision, reducing the number from several involved in typical laparoscopic procedures. Older, and more popular surgical robotic systems, such as the da Vinci Surgical System, are now being tested by physicians who are at controls more than 1,000 miles away. Probably a lot of the same misgivings that people have about autonomous cars apply here, too.
