  1. What If We Lost the Sky?

    Science · Earth · · posted by timothy · from the we'd-still-have-the-space-needle dept. · 421 comments
    HughPickens.com (3830033) writes "Anna North writes in the NYT that a report released last week by the National Research Council calls for research into reversing climate change through a process called albedo modification: reflecting sunlight away from earth by, for instance, spraying aerosols into the atmosphere. But such a process could, some say, change the appearance of the sky — and that in turn could affect everything from our physical health to the way we see ourselves. "You'd get whiter skies. People wouldn't have blue skies anymore." says Alan Robock. "Astronomers wouldn't be happy, because you'd have a cloud up there permanently. It'd be hard to see the Milky Way anymore."

    According to Dacher Keltner, a psychology professor at the University of California, losing the night sky would have big consequences. "When you go outside, and you walk in a beautiful setting, and you just feel not only uplifted but you just feel stronger. There's clearly a neurophysiological basis for that," says Keltner, adding that looking up at a starry sky provides "almost a prototypical awe experience," an opportunity to feel "that you are small and modest and part of something vast." If we lose the night sky "we lose something precious and sacred." "We're finding in our lab that the experience of awe gets you to feel connected to something larger than yourself, see the humanity in other people," says Paul K. Piff. "In many ways it's kind of an antidote to narcissism." And the sky is one of the few sources of that experience that's available to almost everybody: "Not everyone has access to the ocean or giant trees, or the Grand Canyon, but we certainly all live beneath the night sky."

    Alan Robock says one possible upside of adding aerosols could be beautiful red and yellow sunsets as "the yellow and red colors reflect off the bottom of this cloud." Robock recommends more research into albedo modification: "If people ever are tempted to do this, I want them to have a lot of information about what the potential benefits and risks would be so they can make an informed decision. Dr. Abdalati says deploying something like albedo modification is a last-ditch effort. "We've gotten ourselves into a climate mess. The fact that we're even talking about these kinds of things is indicative of that."

  2. Algal Biofuels Not Ready For Scale-Up

    Hardware · Power · · posted by Soulskill · from the it's-not-easy-being-green dept. · 179 comments
    Tator Tot writes with this quote from Chemical & Engineering News: "Using today's technologies and knowledge, a scale-up of fledgling algal biofuel production sufficient to meet even 5% of U.S. transportation fuel demand is unsustainable, says a report released last week by the National Research Council. The report examines the efficiency of producing biofuels from microalgae and cyanobacteria with respect to energy, water, and nutrient requirements and finds that the process falls short. The energy from algal biofuel, the report finds, is less than the energy needed to make it. In terms of water, at least 32.5 billion gal would be needed to produce 10 billion gal of algae-based biofuels, the report states. The study also finds that making enough algal biofuels to replace just 5% of U.S. annual transportation fuel needs would require 44–107% of the total nitrogen and 20–51% of the total phosphorus consumed annually in the U.S."

  3. Exploring Antarctica

    Science · Science · · posted by michael · from the don't-forget-your-mittens dept. · 195 comments
    dargaud writes "There will soon be some firsts on the high Antarctic plateau: after getting 150km from it last year a Chinese expedition plans on reaching Dome A, the highest part of the Antarctic ice sheet (4200m), farthest to reach and coldest place on Earth, untrodden yet. Then in a few months the French-Italian station of Concordia at Dome C (3200m) will open year-round for its first winter-over, of which I will be part. The location of these ice domes make them great for atmospheric physics, glaciology, astronomy and more. Big projects are getting interested in Antarctica again, just in time for the International Polar Year of 2007, 50 years after the first one."

  4. New Science Museum - Now With Real Science!

    Science · Education · · posted by timothy · from the sciencey-goodness dept. · 242 comments
    OpenYourEyes writes "There is a new science museum, run by the National Academy of Science, that has opened in DC. So what? Unklike many museums which simplify their message or use fake data, the exhibits at the Koshland Science Museum are all based on real research, real reports, and real science. Each one contains references to the research reports and data they are based on. Exhibits on DNA, for example, use actual (and long!) DNA sequences to help illustrate how DNA plays a role in disease, agriculture, and criminology. There are also exhibits on Global Climate Change and The Wonders of Science."

  5. Glowing Fish are First Genetically Engineered Pets

    Science · Biotech · · posted by CowboyNeal · from the favorite-stoner-pets dept. · 361 comments
    securitas writes "It was bound to happen. Texas-based biotechnology company Yorktown Technologies will start selling a 'genetically engineered aquarium fish that glows in the dark.' The trademarked GloFish -- 'a tropical zebra fish infused with the gene of a sea anemone that makes it glow fluorescent red' -- is first genetically engineered pet. The possible consequences of introducing a new trangenic species into the environment has touched off a debate that has critics such as the National Academies of Science and the Center for Food Safety calling for a ban on the sale of the fish unless the FDA regulates and approves it. The fish go on sale in January 2004. You can see photos of the GloFish here. Cool, but it's no Blinky." M : I think these guys are marketing the fish for a Taiwanese company.

  6. Slashback: Australia, Nomenclature, Books

    Slashback · · posted by ryuzaki0 · from the harmonious dept. · 205 comments
    Slashback tonight brings a few updates on topics ranging from linux.conf.au and free books online to how you can help pay off Dan Peng's legal debt to the RIAA. Read on below for the details. Since you can never hear enough about linux.conf.au Kimberly Shelt writes: "Actually I wrote a whole article about it this month. Complete with hype about Kfishes, miniconf etc :) It included the direct link to the current LCA2004 pages :) and a tiny pic of scrubby :) what more can you want :)"

    Please, no more name changing. suqur writes "As a follow-up to many stories previously posted, News.com reports that the recently renamed Mozilla Firebird browser (previously known as Phoenix) has finally given up on its new name, and relinquished the name. The new names for the Mozilla Firebird and Mozilla Thunderbird will be Mozilla Browser and Mozilla Mail, respectively. Looks like they're right back where they started, eh?"

    Whatever the name, Mozilla is still only almost perfect: GeekLife.com writes "An old Mozilla exploit continues to crash almost any version/flavor of Mozilla with just 5 lines of plain HTML code (no JavaScript, ActiveX, etc.). If you're very brave, you can test/crash your Mozilla by going here.

    It's important to report fairly on issues like this, or people will come to think of the Open Source journals as biased, uninformative, irresponsible propaganda machines, which will greatly harm any legitimate cause that the OS folks are promoting."

    Books to download, at varying prices. Scott Pendergrast writes "We're working here at Fictionwise to convince publishers to release Neal Stephenson's works as eBooks. Recently his Cryptonomicon work finally became available in Secure Microsoft and Palm Reader formats (yes, the irony of this title being sold in an encrypted format is not missed ;-)

    To encourage sales of this title, which hopefully will result in more of his works becoming ebooks, we're offering a 50% micropay rebate on it (so we're actually losing a bit on each sale)."

    If you like your books free and non-fiction, though, mindpixel writes "I am not lying. The National Academies Press which was created by the National Academies to publish the reports issued by the National Academy of Sciences, the National Academy of Engineering, the Institute of Medicine, and the National Research Council, all operating under a charter granted by the Congress of the United States, has more than 2,500 free, searchable, high quality books online. Some random examples:

    This ought to be tax-deductable, too! ThreeToe writes "Recently the RIAA settled a lawsuit with four college students; one of them was Daniel Peng of Princeton University. Daniel is accepting donations to help pay his $15,000 settlement fee along with related legal fees. You can send money via paypal by clicking here. Remember that Daniel simply wrote an MP3 search engine; he didn't distribute MP3s himself. Those who share my belief that this lawsuit was wrong-headed should make a statement by assisting Daniel."
