    6 Nov 2009 | 6:57 am
    I’m at the AAAI Fall Symposium session on Biologically Inspired Cognitive Architectures, and there was a really interesting talk by Walter Schneider of Pitt about progress in mapping the nerve bundles that are the “information superhighways” between the various parts of the brain.  You’ll find his slides from last year’s talk on his home page, and there has apparently been progress amounting to a breakthrough in the interim. This and fMRI together are giving us an understanding of what’s going on in the brain that’s advancing faster than anybody…

  • Is Robo Habilis a gateway to Intelligence?

    J. Storrs Hall
    5 Nov 2009 | 12:31 am
    In response to my Robo Habilis post, Tim Tyler replied: An intelligence challenge should not involve building mechanical robot controllers – IMO. That’s a bit of a different problem – and a rather difficult one – because of the long build-test cycle involved in such projects. There are plenty of purer tests of intelligence that use more abstract ideas – games, puzzles, and other classical intelligence test fodder. If you want to measure the abilities of mechanical robots, then fine, but let’s not pretend that it’s the same thing as measuring intelligence. This is a fairly widely…

    Molecular manufacturing designs have traditionally looked a lot more like machines than like life's biochemistry, and molecular manufacturing has even been criticized for not taking more inspiration from life's techniques. But there is a fundamental connection between them. The digital nature of chemistry (to be specific, molecule-forming chemistry) is what will allow molecular manufacturing systems to build duplicate systems, driving down the cost of manufacturing and enabling high throughput and large products. It's easy to think of life as squishy and analog, or complex and…

    26 Oct 2009 | 9:42 am
    Richard Denison, Ph.D., is a Senior Scientist. It’s got pictures of kids and families.  People of all colors.  Gentle hands cradling our fragile planet.  A hard hat resting on a pair of worn work gloves and a hammer.  It says the coalition is “people like you.”  It bears an uncanny resemblance to the website of the Safer Chemicals, Healthy Families campaign, of which EDF is a founding member.  But dig deeper and you’ll discover that the website of the “Coalition for Chemical Safety” is actually created and run by industry. It actually takes quite a…

  • ChAMP “superseded”: EPA shifts into action mode

    Richard Denison
    1 Oct 2009 | 2:30 pm
    Richard Denison, Ph.D., is a Senior Scientist. A new entry showed up sometime in the last day on EPA’s webpage for its ChAMP initiative.  It reads:  “The Chemical Assessment and Management Program (ChAMP) has been superseded by the comprehensive approach to enhancing the Agency’s current chemicals management program announced by Administrator Lisa Jackson on September 29, 2009.”  Don’t miss this bit at the top of the page: Yes, that image is a cobweb, which EPA uses to designate archived web content.  What’s happening here? Lost in the buzz surrounding EPA…

  • Straight from the Horse’s Mouth: EPA Antes Up on TSCA Reform

    Richard Denison
    29 Sep 2009 | 6:10 pm
    Richard Denison, Ph.D., is a Senior Scientist. Today, EPA Administrator Lisa Jackson unveiled the Obama Administration’s “Essential Principles for Reform of Chemicals Management Legislation.”  The principles’ significance lies not so much in the words they contain, but rather in what they symbolize:  A clear confirmation that this Administration understands that the Toxic Substances Control Act (TSCA) needs fundamental reform and that it is ready and willing to engage in making it happen. There’s no shortage of principles and platforms for TSCA reform, of…

  • Talk about over-reaching: Anti-REACH screed gets nearly everything wrong

    Richard Denison
    26 Aug 2009 | 2:38 pm
    Richard Denison, Ph.D., is a Senior Scientist. In an opinion piece titled “Chemical regulators have overreached” in the August 27, 2009 issue of Nature, two prominent animal welfare advocates claim that vastly larger numbers of chemicals will have to be tested under the European Union’s REACH regulation than previously estimated, and hence that 20 times more laboratory animals will be sacrificed.  They call for a moratorium on some animal tests.  Well, a closer look reveals that it’s the opiners themselves that have greatly overreached. [Update 8/28:  The European…

  • The nanotube SNURs: Nano step forward, nano step back

    Richard Denison
    21 Aug 2009 | 2:29 pm
    Richard Denison, Ph.D., is a Senior Scientist. In June, EPA published a Federal Register notice that included Significant New Use Rules (SNURs) for two carbon nanotubes (as well as 21 other chemicals).  That notice certainly got the attention of lawyers in town (see here, here and here).  The nanotube SNURs would require anyone planning to produce or process either of the two substances to notify EPA if the person intended not to comply with the (rather limited) risk management conditions specified by EPA.  Well, as reported yesterday by Sara Goodman of E&E News, EPA is now withdrawing…

  • Do scientists encourage misleading media coverage?

    As scientists, how we love to rail against the incompetence of the media.  As self-proclaimed keepers of the truth, we decry - usually rather vocally - the misinterpretation and misuse of our precious studies.  And as we commiserate together on the injustices of the world, we inevitably get to thinking ...

    5 Nov 2009 | 6:10 pm
    Not necessarily the bestmath education In response to my last post, which mentioned some high points in Indian education, a comment by fiaorsh offers some perspective on the extensive low points. Since my reply ended up looking more like a post, I’m making it one: @ fiaorsh — You make some important points regarding education in India, and I’d like to offer some additional context and perspective. First, your remarks are a good reminder of the astounding diversity of India, and why one must avoid generalizations about the education system or anything else. The statement I quoted…

    2 Nov 2009 | 9:14 pm
    Regional languages of India Rosa recently returned from Ashoka meetings in Chennai and Hyderabad, reminding me of some information I’d collected about Indian visits to my website, E-drexler.com. India is enormously diverse (e.g., many cultures, 18 officially recognized regional languages, and very different state governments), and I became curious about where inside India this traffic was coming from. Here’s a map showing where visits originated during an interval of about five days: I was impressed with the broad geographic distribution of visitors, and I’ve also noticed that,…

    Ongoing research The previous post, “Nanotechnology research papers: The world’s most prolific authors”, had statistics that suggested (but didn’t directly indicate) a large global role for nanotechnology research in China. This was discussed in the comments, where Patrick, in particular, noted some of the relevant questions and difficulties with the analytical categories. I pointed to a source that addresses the topic more directly, and Patrick pointed to another. Regarding the first: Questions of quantity and quality are addressed in a 2006 paper, “The Emergence of China as a…

Five of the six most popular posts in the blog’s first year (and several more in the top 20) have been, not about news or about the specifics of a technology, but instead about something deeper and more durable: knowledge itself — the structure of science, how scientific and engineering knowledge fit together at the most fundamental level, and how to acquire a broad, integrated understanding of it all: How to Learn About Everything How to Understand Everything (and Why) A Map of Science The Antiparallel Structures of…

    3 Nov 2009 | 1:50 am
    Image obtained from “HAI Watch: Not on My Watch” web site Recently it began to be some concern about the Healthcare-associated infections (HAI), as evidenced by initiatives such as the prevention campaign Kimberly-Clark Health Care, called HAI Wactch: Not on My Watch. Perhaps similar technologies to the one used in the anti-swine flue costumes design by Haruyama Trading Company which is based on titanium dioxide nanoparticles may facilitate prevention. If these new nanomaterials demonstrate its effectiveness we could find ourselves in a new era in the field of disease prevention. But…

  • Ice, Snow & Nano

    6 Nov 2009 | 12:41 pm
    As anyone looking at trees the last week or so has noticed, the leaves have taken on the red, yellow, orange and brown hues of Autumn. The cool crisp days and evenings signal that Fall has arrived. And to paraphrase Shelley, "If Fall comes, can Winter be far behind?" And with Winter comes snow, sleet, and freezing rain. The latter of that trio is the one that, at least in the DC area, causes something that all drivers fear most, that thin coating of ice on roadways that makes driving in Winter a challenge. For pedestrians on sidewalks, it can cause slips and falls that could…

MIT Technology Review reports on the work of Arizona based Fluidic Energy who are working toward development of a metal-air battery that relies on ionic liquids, instead of an aqueous solution, as its electrolyte.The company aims to build a Metal-Air Ionic Liquid battery that has up to 11 times the energy density of the top lithium-ion technologies for less than one-third the cost. Cody Friesen, a professor of materials science at Arizona State and founder of Fluidic Energy, says the use of ionic liquids overcomes many of the problems that have held back metal-air batteries in the past.The…

  • Electric Solar Wind Sail Could Have Five Times Higher Thrust

    noreply@blogger.com (bw)
    6 Nov 2009 | 3:41 pm
    An electric solar wind sail is a recently introduced propellantless space propulsion method whose technical development has also started. The electric sail consists of a set of long, thin, centrifugally stretched and conducting tethers which are charged positively and kept in a high positive potential of order 20 kV by an onboard electron gun. The positively charged tethers deflect solar wind protons, thus tapping momentum from the solar wind stream and producing thrust. The amount of obtained propulsive thrust depends on how many electrons are trapped by the potential structures of the…

  • Acceleration of Neutral Atoms with Lasers With Acceleration Up to 100 trillion Gs

    Researchers observed previously unconsidered strong kinematic forces on neutral atoms in short-pulse laser fields. The ponderomotive force on electrons is the driving mechanism, producing ultra-strong acceleration of neutral atoms greater that Earth's gravitational acceleration by 14 orders of magnitude. A force of such strength may lead to new applications in both fundamental and applied physics.

    Day 3 also appears to be done with no change in the standings or prizes won. Lasermotive has won the level 1 prize of $900,000. No other prizes were won and no other team qualified for a prize.LaserMotive retained their lead, and inched closer to the 5 m/s benchmark – they removed some payload, and thus ran a bit faster – the official times were 3:49 and 3:48 – 13 seconds faster, in fact, for a speed of 3.9 m/s. The payload was about 200 grams lighter – 0.4 kg (unofficial), for an unofficial score of 3.9 * 0.4 / 4.8 = 0.325.Kansas City still failed short of reaching the top, though it…

    I almost found myself agreeing with our neighbours (across the road from Foxbat) at the Ecologist, which gave me a bit of a shock. The article in question concerned antimicrobials, and nanosilver in particular, and I have to admit that I’m more likely to be encouraging my kids to eat earthworms than to spraying them with antibacterial agents. As the old adage goes, you have to eat a peck of dirt before you die, and with good reason. But we also have to ask, yet again: why have we become so frightened of ‘germs’ that we feel the need to go to ever more extreme measures to…
