Minnesota Introduces World's First Carbon Tariff 303

Posted by timothy from the hey-cut-that-crap-out dept.
hollywoodb writes "The first carbon tax to reduce the greenhouse gases from imports comes not between two nations, but between two states. Minnesota has passed a measure to stop carbon at its border with North Dakota. To encourage the switch to clean, renewable energy, Minnesota plans to add a carbon fee of between $4 and $34 per ton of carbon dioxide emissions to the cost of coal-fired electricity, to begin in 2012 ... Minnesota has been generally pushing for cleaner power within its borders, but the utility companies that operate in MN have, over the past decades, sited a lot of coal power plants on the relatively cheap and open land of North Dakota, which is preparing a legal battle against Minnesota over the tariff."

Astronomers Discover 33 Pairs of Waltzing Black Holes 101

Posted by ScuttleMonkey from the teach-them-to-foxtrot dept.
Astronomers from UC Berkeley have identified 33 pairs of waltzing black holes, closing the gap somewhat between the observed population of super-massive black hole pairs and what had been predicted by theory. "Astronomical observations have shown that 1) nearly every galaxy has a central super-massive black hole (with a mass of a million to a billion times the mass of the Sun), and 2) galaxies commonly collide and merge to form new, more massive galaxies. As a consequence of these two observations, a merger between two galaxies should bring two super-massive black holes to the new, more massive galaxy formed from the merger. The two black holes gradually in-spiral toward the center of this galaxy, engaging in a gravitational tug-of-war with the surrounding stars. The result is a black hole dance, choreographed by Newton himself. Such a dance is expected to occur in our own Milky Way Galaxy in about 3 billion years, when it collides with the Andromeda Galaxy."

Sharp Rise In Jailing of Online Journalists; Iran May Just Kill Them 233

Posted by timothy from the your-ethics-may-vary dept.
bckspc writes "The Committee to Protect Journalists has published their annual census of journalists in prison. Of the 136 reporters in prison around the world on December 1, 'At least 68 bloggers, Web-based reporters, and online editors are imprisoned, constituting half of all journalists now in jail.' Print was next with 51 cases. Also, 'Freelancers now make up nearly 45 percent of all journalists jailed worldwide, a dramatic recent increase that reflects the evolution of the global news business.' China, Iran, Cuba, Eritrea, and Burma were the top 5 jailers of journalists." rmdstudio writes, too, with word that after the last few days' protest there, largely organized online, the government of Iran is considering the death penalty for bloggers and webmasters whose reports offend it.

Submission + - WHO Says Swine Flu May Have Peaked in US

Submitted by
Hugh Pickens
Hugh Pickens writes: "The NY Times reports that the World Health Organization (WHO) says that there were “early signs of a peak” in parts of the Northern Hemisphere, including the United States while the American College Health Association, which surveys more than 250 colleges with more than three million students, said new cases of flu had dropped 27 percent in the week ending November 13 from the week before, the first drop since school resumed in the fall. Nonetheless, Dr. Anne Schuchat, the director of vaccination and respiratory disease at the CDC, chose her words carefully. "We are in better shape today than we were a couple of weeks ago," Schuchat says. “I wish I knew if we had hit the peak. Even if a peak has occurred, half the people who are going to get sick haven’t gotten sick yet." Privately, federal health officials say they fear that, if they concede the flu has peaked, Americans will become complacent and lose interest in getting vaccinated, increasing the chances of another wave. However Dr. Lone Simonsen, a former CDC epidemiologist, says she expects a third wave in December or January, possibly beginning in the South again. Based on death rates in New York City and in Scandinavia, Simonsen argues that both 1918 and 1957 had mild spring waves followed by two stronger waves, one in fall and one in midwinter adding that in the pandemic of 1889, the bulk of the deaths occurred in the third wave. “If people think it’s going away, they can think again,” Dr. Simonsen says."

Demo of a New "Sixth Sense" Technology 187

Posted by kdawson from the i-see-live-data dept.
TEDChris writes "Here's an intriguing attempt at a versatile new tech device that tries to augment the wearer's five senses. It comes out of Patty Maes's group at the MIT Media Lab. By combining a computerized personal projector with a camera and linking both to the Net, a host of surprising new applications becomes possible. This 8-minute demo created a lot of buzz at TED last month and was posted online today. Would love to know what the Slashdot community makes of it."

The Science of the Lightsaber 197

Posted by samzenpus from the the-force dept.
Smartcowboy writes "Chances are that you have seen a lightsaber at one time or another, whether on the evening news or down at the local cantina. Therefore you know that a lightsaber is an amazing and versatile device that is able to cut through nearly anything in a matter of milliseconds. Have you ever wondered how these remarkable weapons work? Where does the energy come from, and how are they able to contain that energy in a rod-like column of glowing power? In this article, you will have a chance to look inside a lightsaber and discover the source of its incredible characteristics." I was sure the blade was made from the focused hate and disappointment of the last three movies.

Feed Science Daily: Life Expectancy Of Americans Reaches 78 (sciencedaily.com)

A child born in the United States in 2005 can expect to live nearly 78 years (77.9) -- a new high -- according to a new report released by the Centers for Disease Control and Prevention. The increase in life expectancy represents a continuation of a long-running trend. Over the past decade, life expectancy has increased from 75.8 years in 1995, and from 69.6 years in 1955.

Feed Science Daily: Enormous Spider Web Found In Texas (sciencedaily.com)

From feed by sdfeed
A massive spider web first spotted covering several acres of oak-elm woodlands along a Lake Tawakoni State Park trail in early August made national and international headlines throughout the Labor Day Weekend. Stumped as to the web's origin, the initial consensus of arachnologists and entomologists who saw an online photo of the web sent by Texas Parks and Wildlife Department biologist Mike Quinn was that it may have resulted from a "mass dispersal" event. In such an event, millions of tiny spiders or spiderlings spin out silk filaments to ride air currents in a phenomenon known as "ballooning."

Feed Engadget: iPhone price drop leads to sales boost (engadget.com)

Shocking, we know. As if the price drops on the PlayStation 3 weren't evidence enough that we all like our gizmos a bit cheaper, a new report from Piper Jaffray analyst Gene Munster claims that iPhone sales skyrocketed shortly after the (hotly contested) price drops. According to his math, Apple needed to sell some 136,000 iPhones between September 5th (the day of the cuts) and September 9th (the day Apple claimed to have sold one million of its mobiles), which meant that 27,000 iPhones per day were getting unboxed in the five-day period. Comparatively, Munster approximated that Cupertino was unloading around 9,000 iPhones per day prior to the price cuts. 'Course, even Gene doubts that the recent sales surge will be able to hold steady, but we'd say the slashings have already had their desired effect.

Feed Techdirt: Blaming MP3s And iPods For Ruining Music (techdirt.com)

From feed by techdirtfeed
It seems that with every new generation of music delivery, there are going to be people who complain that the quality just isn't up to par with what came before. Remember when CDs first came out, there were quite a few upturned noses who insisted the sound quality just couldn't compete with vinyl LPs. And now that mp3s are becoming the standard, folks are complaining that the quality simply can't live up to CDs. This has certainly gone on for a while, as we've noted there are even online stores that cater to audiophiles who believe that compressed mp3s just aren't worth listening to. However, now it's going even further, as the WSJ claims that some audio engineers are saying that the popularity of mp3s and iPods is ruining music. The theory is that audio engineers are using iPods and mp3s as the lowest common denominator for recordings. Since they know that so many people are going to end up hearing the song just through the cheap white earbuds of an iPod, that they don't bother to make a high quality recording that would sound better on high end stereo equipment. Thus, the claim goes, pretty much all music is sounding somewhat crappy, and it's turning people off from the latest crop of new songs. In other words, music is less popular today, because the songs are engineered to sound like crap. This seems silly. It's certainly a different argument than the industry's typical claim that downloads are killing the music business -- but it's equally ridiculous. Sure, there may be some engineers who are doing a cruddy job in engineering the music, but as one audio engineer in the story notes, there's no reason to ever engineer a song "down" to mp3 levels. Instead, you should just engineer it to a higher level and it'll sound fine on a CD as well on an iPod. However, to put the whole thing in perspective: songs compressed to mp3 level certainly do lose some quality at the margin, but there's only a small group of audiophiles who really care or will notice on a regular basis. At the same time, compare that to how much more music is being produced today thanks to cheaper production tools and easier distribution of music through the internet, and I think you could make the case that the mp3 and the iPod has done a lot more to improve music than to hurt it.

NSF-Funded "Dark Web" to Battle Terrorists 258

Posted by ScuttleMonkey from the whos-watching-the-watchers dept.
BuzzSkyline writes "The National Science Foundation has announced a new University of Arizona project, which they call the Dark Web, intended to monitor all terrorist activity on the Internet. The project relies on 'advanced techniques such as Web spidering, link analysis, content analysis, authorship analysis, sentiment analysis and multimedia analysis [to] find, catalog and analyze extremist activities online.' The coolest part of the project is a tool called Writeprint, which 'automatically extracts thousands of multilingual, structural, and semantic features to determine who is creating "anonymous" content' with an accuracy of 95%, according to the release."

I remember reading about asynchronous chip design (I wish I knew where) and the reason they gave for the non-existence of asynchronous chips is that there is no framework support for it, meaning, they don't teach how to design asynchronous circuits in universities (at least not as the main way of doing things) and there is no software to help chip designers to design asynchronous chips.
