It seems that the internet as we knew it is about to pass away, giving way to a much more controlled environment where websites can code what can and what can’t be done with so-called ‘content’, which becomes something akin to a controlled substance.
David Bollier, in his recent article
The Piecemeal Privatization of Web Infrastructure
relates how the governing entity for the web, the World Wide Web Consortium or W3C, is working on standards that will incorporate Digital Rights Management (DRM) right into the guts of the internet’s language. HTML-5, the next version of the language that displays websites and other things on the net, will be armed … with DRM.
Langdon Cook: "In early August I got a call from a producer for the PBS TV series Food Forward. He had seen a review copy of my new book, The Mushroom Hunters: On the Trail of an Underground America, and wanted to film itinerant mushroom harvesters for an episode on wild foods. I knew just the guy to talk to.
Doug is one of the characters in my book. He's been hunting mushrooms commercially in the Pacific Northwest for 30 years. Before that he was a logger and he also captained a crab boat. Sometimes Doug cuts steel to make a little extra cash or digs razor clams. He's been roaming up and down the West Coast for decades doing outdoor jobs to pay the bills, mostly picking mushrooms. In recent years I've been roaming with him, meeting the pickers and buyers who work in a hidden economy known as the mushroom trail. Many of the pickers are refugees -- from the Old Economy at home or war-torn countries abroad. They move with the seasons, preferring the fluctuations of a crop tended by nature (and the Gold Rush hope of hitting the mother lode) to the more stable yet monotonous alternative of agricultural work."

The internet providers and copyright holders have begun using peer-to-peer (P2P) surveillance methods to try to sniff out when copyrighted content is uploaded or shared illegally.
A company called MarkMonitor has been contracted to join BitTorrent networks (the most common way to illegally share files) and search for the names of copyright-protected movies, music, and TV shows. The list of those names is provided by the MPAA, RIAA, and NCTA.
When MarkMonitor finds a file in violation, they snag the IP address of the user who's sharing the file and send it off to that user's internet provider, who issues a series of escalating warnings.
Researchers from North Carolina State University have developed a de facto antibiotic “smart bomb” that can identify specific strains of bacteria and sever their DNA, eliminating the infection. The technique offers a potential approach to treat infections by multi-drug resistant bacteria.
“Conventional antibiotic treatments kill both ‘good’ and ‘bad’ bacteria, leading to unintended consequences, such as opportunistic infections,” says Dr. Chase Beisel, an assistant professor of chemical and biomolecular engineering at NC State and senior author of a paper describing the work. “What we’ve shown in this new work is that it is possible to selectively remove specific strains of bacteria without affecting populations of good bacteria.”
The new approach works by taking advantage of a part of an immune system present in many bacteria called the CRISPR-Cas system. The CRISPR-Cas system protects bacteria from invaders such as viruses by creating small strands of RNA called CRISPR RNAs, which match DNA sequences specific to a given invader. When those CRISPR RNAs find a match, they unleash Cas proteins that cut the DNA.
The NC State researchers have demonstrated that designing CRISPR RNAs to target DNA sequences in the bacteria themselves causes bacterial suicide, as a bacterium’s CRISPR-Cas system attacks its own DNA.
Pathogenic oomycetes have evolved RXLR effectors to thwart plant defense mechanisms and invade host tissues. We analysed the function of one of these effectors (Penetration-Specific Effector 1 (PSE1)) whose transcript is transiently accumulated during penetration of host roots by the oomycete Phytophthora parasitica.Expression of PSE1 protein in tobacco (Nicotiana tabacum and Nicotiana benthamiana) leaves and in Arabidopsis thaliana plants was used to assess the role of this effector in plant physiology and in interactions with pathogens. A pharmacological approach and marker lines were used to charcterize the A. thaliana phenotypes.Expression of PSE1 in A. thaliana led to developmental perturbations associated with low concentrations of auxin at the root apex. This modification of auxin content was associated with an altered distribution of the PIN4 and PIN7 auxin efflux carriers. The PSE1 protein facilitated plant infection: it suppressed plant cell death activated by Pseudomonas syringae avirulence gene AvrPto andPhytophthora cryptogea elicitin cryptogein in tobacco and exacerbated disease symptoms upon inoculation of transgenic A. thalianaplantlets with P. parasitica in an auxin-dependant manner.We propose that P. parasitica secretes the PSE1 protein during the penetration process to favour the infection by locally modulating the auxin content. These results support the hypothesis that effectors from plant pathogens may act on a limited set of targets, including hormones.
Philosophers and scientists have long puzzled over where human imagination comes from. In other words, what makes humans able to create art, invent tools, think scientifically and perform other incredibly diverse behaviors?
The replication of a historic whisky might reflect merely our fascination with artificial artifacts---but the whisky yielded a surprise...
During the 1908 Nimod expedition, the ill-equipped British adventurer Earnest Shackleton attempted to be the first to reach the South Pole. Having failed to do so less than 100 miles short of his destination, he abandoned the continent–and the entire contents of his supply huts. In 2007, mycology experts recommended cleaning out the ice under one of the huts on Ross Island to help stave off an invasion of hungry Antarctic fungi. In the process, conservators discovered three crates of Mackinlay’s Rare Old Highland Malt Whisky, apparently left by Shackleton or a member of his crew.
The Mesh Potato is a device for providing low-cost telephony and Internet in areas where alternative access either doesn't exist or is too expensive. It is a marriage of a low-cost wireless access point (AP) capable of running a mesh networking protocol with an Analog Telephony Adapter (ATA).
As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
