  • The five kinds of nanotechnology

    3 Apr 2014 | 7:56 pm
    Why understanding seems stuck: I count five kinds of nanotechnology, of which only three are called by that name. Of the three, one is a revolutionary prospect, one is a fantasy, and the third is mostly materials science. As for the other two kinds, one is the heart of today’s greatest technological revolution, while the other is the basis for progress toward the revolutionary prospect — but neither of these is called “nanotechnology”. This may seem confusing, and it is. Indeed, people who think they know something about “nanotechnology” often have a lot to unlearn, and would be…
  • Space Based Solar power need robotic assembly in space and reusable rockets for viability

    Next Big Future

    School children learn the difference between liquids and gases, but centuries of scholarship have failed to produce consensus about how to categorize glass. Now, combining theory and numerical simulations, researchers have resolved an enduring question in the theory of glasses, showing that their energy landscapes are far rougher than previously believed. The new model shows that molecules in glassy materials settle into a fractal hierarchy of states.

  • Your T-shirt's ringing: Printable tiny flexible cell phones for clothes?

    24 Apr 2014 | 7:28 am
    A new version of 'spaser' technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing. A spaser is effectively a nanoscale laser or nanolaser. It emits a beam of light through the vibration of free electrons, rather than the space-consuming electromagnetic wave emission process of a traditional laser.
  • Gold nanoparticles help target, quantify breast cancer segments in a living cell

    23 Apr 2014 | 10:26 am
    A way to detect and measure cancer levels in a living cell by using tiny gold particles with tails of synthetic DNA has been developed by scientists. The process uses gold nanoparticles to target and bind to fragments of genetic material known as BRCA1 messenger RNA splice variants, which can indicate the presence and stage of breast cancer. The number of these mRNA splice variants in a cell can be determined by examining the specific signal that light produces when it interacts with the gold nanoparticles.

    Credit: Intravaia et al. Whether or not MEMS (microelectromechanical systems) technology has use as a development path toward productive nanosystems, or atomically precise manufacturing, is unclear (see for example this series of posts on the Feynman Path by J. Storrs Hall), the problem of stiction in microscale mechanical systems has been used as a canard to criticize proposals for mechanical molecular machine systems. (For why this criticism is unfounded, see section 6.3.7 of Kinematic Self-Replicating Machines.) Nevertheless, MEMS is in its own right a very useful technology so it is…

  • The perverting of prioritization: How a good idea for TSCA reform went bad – and how to save it

    Richard Denison
    22 Apr 2014 | 7:26 am
    By Richard DenisonRichard Denison, Ph.D. is a Lead Senior Scientist. For years, the concept of prioritization as an element of TSCA reform has enjoyed support from a broad array of stakeholders.  The number of chemicals in active commerce is large, if uncertain:  surely less than the 85,000 listed on the TSCA Inventory, but still in the tens of thousands. That sheer number demands that EPA develop and apply a process to decide where to start and how to sequence the enormous task of reviewing the safety of those chemicals.  There has also been widespread agreement that EPA should make an…

    Last week’s Physics Quiz asked about errors in Wikipedia’s current diagram of the Standard Model. Here’s the diagram with corrections; answers follow: What do the arcs represent? The Standard Model interactions between particles: the boson-mediated strong, weak, and electromagnetic forces. Which of the arcs is incorrect? [And a question that got lost: Where is an arc is missing?] The arc linking charged and uncharged leptons is spurious: It does not represent a force. The arc representing the Higgs-neutrino interaction was omitted (see also #4). Extra credit, Wikipedia history…

A recent book by historian Patrick McCray – The Visioneers: How a Group of Elite Scientists Pursued Space Colonies, Nanotechnologies, and a Limitless Future – follows this story, setting its origins in the context of its times, and argues that O’Neill and Drexler are archetypes of a distinctive…
  • What’s the best way of harvesting the energy of the sun?

    Richard Jones
    6 Apr 2014 | 11:09 pm
    This is another post inspired by my current first year physics course, The Physics of Sustainable Energy (PHY123). Calculations are all rough, order of magnitude estimates – if you don’t believe them, try doing them for yourself. We could get all the energy we need from the sun, in principle. Even from our cloudy UK skies an average of 100 W arrives at the surface per square meter. Each person in the UK uses energy at an average rate of 3.4 kW, so if we each could harvest the sun from a mere 34 square meters with 100% efficiency, that would do the job. For all 63 million of us,…

    I wrote this short piece for the online magazine The Conversation as a comment on the government’s response to the Witty Review on universities and economic growth. It was published there as Budget 2014: cash for research set against an overall story of long-term decline; as the new title suggests it was edited to give more prominence to the new science-related announcements in the Budget. Here’s the original version. Current UK innovation policy has taken on a medieval cast; no sooner do we have “Catapult Centres” for translational research established, than there is…
  • What should we do about climate change? Two opposing views, and they’re both wrong

    Richard Jones
    6 Mar 2014 | 5:53 am
    In the last 250 years, humanity has become completely dependent on fossil fuel energy. This dependence on fossil fuels has materially changed our climate; these changes will continue and intensify in the future. While uncertainty remains about the future extent and consequences of climate change, there is no uncertainty about the causal link between burning fossil fuel, increasing carbon dioxide concentrations in the atmosphere, and a warming world. This summarises my previous two long posts, about the history of our fossil fuel dependence, and the underlying physics of climate change. What…

    In another post inspired by my current first year physics course, The Physics of Sustainable Energy (PHY123), I suggest how a physicist might think about climate change. The question of climate change is going up the political agenda again; in the UK recent floods have once again raised the question of whether recent extreme weather can be directly attributed to human-created climate change, or whether such events are likely to be more frequent in the future as a result of continuing human induced global warming. One UK Energy Minister – Michael Fallon – described the climate…

    Aviation Week has a review of Space Based Solar power projects.IEEE spectrum indicates that Japan's Space Agency has a roadmap for a 1 Gigawatt space based solar power system in 2031.All of the old space based solar power designs are not workable. They are too big and too heavy.Reusable rockets and the Spacex Heavy will help make launches cheaper, but it is robotic assembly in space that will have more impact.Spiderfab will use robots to assemble structures in space. Spiderfab on orbit assembly can reduce the mass of space structures by 30 times.Also, the space based power should be used…
  • Japan will boost GPS accuracy to about 1-3 centimeters of error instead of up to 10 meters currently

    24 Apr 2014 | 10:17 am
    Mitsubishi Electric is ready to launch the first commercial, nationwide, centimeter-scale satellite positioning technology. The Quazi-Zenith Satellite System (QZSS), will augment Japan’s use of the U.S.-operated Global Positioning System (GPS) satellite service. By precisely correcting GPS signal errors, QZSS can provide more accurate and reliable positioning, navigation, and timing services.To correct the errors, a master control center compares the satellite’s signals received by the reference stations with the distance between the stations and the satellite’s predicted location.

    A year ago, the state’s brownfields redevelopment fund ran dry, stalling or delaying roughly two-dozen projects across the state. But the bulldozers and backhoes are going to start moving again, now that lawmakers have approved $15 million for the fund. Advocates, led by the Massachusetts Smart Growth Alliance, aren’t going to stop there. They say that injection of cash in a supplemental budget that became law last month is nowhere near enough to address the pressing backlog. The group sent…

    It’s not the victory that the Patrick administration and the local business community had sought. But at least it’s something, right? Gov. Deval Patrick says he was told today by the U.S. Health and Human Services Secretary Kathleen Sebelius that the state has been given an extra year to comply with the rules for “rating factors” under ObamaCare. The state’s health insurers may now continue to use their rating factors — such as breaks tied to a low-risk industry — to help determine…

    The workers at Dunkin’ Donuts might be fast. But they’re just not assembling those egg sandwiches quickly enough for Nigel Travis. The CEO of parent company Dunkin’ Brands told analysts today that the Canton-based coffee shop chain is experimenting with a new sandwich station. The initiative is aimed at significantly boosting a typical Dunkin’ shop’s efficiency. Travis says the company has hired two unnamed universities to study the issue and look for ways to pick up the pace. He also…

    For those of you who have to drive into Boston from the west this weekend, there's good news and there's bad news. First the bad news: The work on the Prudential Tunnel that has necessitated lane closures and long tie-ups for east-bound traffic is back, starting Saturday night. The good news is this is the last weekend of the repair work, and the Department of Transportation has proudly announced that restrictions won't be as severe as the three previous weekends periods of work (the last stretch…
