Hey, it's weird up here - there must be an earthquake in the atmosphere - GeoSpace - AG... - 4 views

  •  
    CNES research to detect warning signs of earthquakes in the ionosphere. Jaxa is also interested in conducting such studies. To my opinion it's worth taken a closer look at what they are doing!!

Boron 'buckyball' discovered - 1 views

  •  
    Jul 13, Nanotechnology/Nanomaterials Researchers have shown that clusters of 40 boron atoms form a molecular cage similar to the carbon buckyball. This is the first experimental evidence that such a boron cage structure exists. Credit: Wang lab / Brown UniversityThe discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research.

10Gbits data transmission using #LEDs #LIFI - 0 views

  •  
    UK researchers say they have achieved data transmission speeds of 10Gbit/s via "li-fi" - wireless internet connectivity using light. The researchers used a micro-LED light bulb to transmit 3.5Gbit/s via each of the three primary colours - red, green, blue - that make up white light. This means over 10Gbit/s is possible.

Interference of thermal waves - Can heat be controlled as waves? - 1 views

  •  
    Imagine a material that only admits thermal conduction for certain temperatures. Martin Maldovan from Georgia Tech holds a tiny thermoelectric device that turns cold on one side when current is applied. Recent research has focused on the possibility of using interference effects in phonon waves to control heat transport in materials. These are exciting news (see Nature Materials paper here http://www.nature.com/nmat/journal/v14/n7/full/nmat4308.html). Heterostructure research lead to outstanding new possibilities when applied to electronic transport (e.g. in quantum well and quantum dots) and to photonics (e.g. Quantum Cascade Laser tunnable lasers). Apparently the time has come to see selective thermal control in this way! Truly exciting!!

scrible | smarter online research - annotate, organize & collaborate on web pages - 2 views

  •  
    A personal need for organizing the information I access online, going away from the pdf print of page, or browser tab just lying open for ages (Anna style) brought me here. Seems to be a quite good and featureful service, sponsored by the NSF.
  •  
    not convinced ... still stick to pdf for time being
  •  
    NSF, NSA, more or less the same. I'm growing increasingly weary about giving increasingly more private data away to online services.

Electromagnetism generated by symmetry breaking in dielectrics - 0 views

  •  
    Using dielectric materials as efficient EM radiators and receivers can scale down these antenna's to the chip level, reducing both weight and power consumption. The infamous internet-of-things one step closer. But could we also transmit power this way?? "In dielectric aerials, the medium has high permittivity, meaning that the velocity of the radio wave decreases as it enters the medium," said Dr Dhiraj Sinha, the paper's lead author. "What hasn't been known is how the dielectric medium results in emission of electromagnetic waves. This mystery has puzzled scientists and engineers for more than 60 years." The researchers determined that the reason for this phenomenon is due to symmetry breaking of the electric field associated with the electron acceleration The researchers found that by subjecting the piezoelectric thin films to an asymmetric excitation, the symmetry of the system is similarly broken, resulting in a corresponding symmetry breaking of the electric field, and the generation of electromagnetic radiation.

Personal Thermal Management by Metallic Nanowire-Coated Textile - 2 views

  •  
    By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. With as extra bonus: Besides providing high levels of passive insulation, AgNW-coated clothing can also provide Joule heating if connected to an electricity source, such as a battery. The researchers demonstrated that as little as 0.9 V can safely raise clothing temperature to 38 °C, which is 1 °C higher than the human body temperature of 37 °C. How about that for personal comfort during the cold winter months

    These applications seem more and more promising. However I wonder about the toxicity aspects of wearing this stuff and apparently some research is starting to be developed to assess that, see http://www.particleandfibretoxicology.com/content/11/1/52 showing results of pulmonary toxicity of AgNW

'Doomsday Ark' to be Housed on the Moon -A Remote Access Toolkit to Rebuild the Human Race - 5 views

  • our future may reside on the Moon if plans.being drawn up for a “Doomsday ark” on the moon by the European Space Agency are carried through.
  • whether living organisms could survive, European Space Agency scientists are hoping to experiment with growing tulips on the moon within the next decade.
  • would initially be run by robots
  •  
    did not know ESA was doing that!
  •  
    too late, the world will in end in 2012 ......... I fail to see in which scenario this would be better than a couple of vaults on Earth (since there would be no humans on the moon). But if tulips on the moon can convince politicians, I'm all for it.
  •  
    "The first flowers - tulips or arabidopsis, a plant widely used in research - could be grown in 2012 or 2015 according to Bernard Foing, chief scientist at the agency's research department." - Bernhard strikes again :-)

The Coolest Antiprotons - 2 views

  • Researchers cooled a cloud of about 4,000 antiprotons down to 9 kelvin using a standard approach for cooling atoms that has never been used with charged particles or ions. The technique could provide a new way to create and trap antihydrogen, which could help researchers probe a basic symmetry of nature.
  • hydrogen and antihydrogen should share many basic traits, like mass, magnetic moment, and emission spectrum. If antihydrogen and hydrogen have even slightly different spectra, it indicates some new physics principles beyond the standard model, a very big deal.
  •  
    antihydrogen propulsion...?
  • ...1 more comment...
  •  
    how to efficiently direct it?
  •  
    didn't roger write an assessment of antimatter propulsion when he was in the ACT?
  •  
    yeah the problem is the amount of antimatter you can get and more specifically how to trap it. I found that you would need around one gram to go to the outer Solar System. So we are far from that, but finding an efficient way to trap it, with an electromagnetic trap rather than solid walls is a first step !

The importance of stupidity in scientific research. - 10 views

  •  
    I suggest you this easy reading ( is on a peer-reviewed scientific journal, IF = 6.14) 'We just don't know what we're doing!!!'
  • ...2 more comments...
  •  
    as a start of a peer reviewed paper this is an interesting first paragraph: "I recently saw an old friend for the first time in many years. We had been Ph.D. students at the same time, both studying science, although in different areas. She later dropped out of graduate school, went to Harvard Law School and is now a senior lawyer for a major environmental organization. At some point, the conversation turned to why she had left graduate school. To my utter astonishment, she said it was because it made her feel stupid. After a couple of years of feeling stupid every day, she was ready to do something else."
  •  
    Hilarious! Mr Schwartz, who made a PhD at Stanford(!) and apparently is working as a postdoc now, has finally discovered what science is about!!! Quote: "That's when it hit me: nobody did. That's why it was a research problem." And he seems so excited about it! I think he should not only get published in 6.14 journal, but also get the Nobel Prize immediately! Seriously, after reading something like this, how one may not have superstitions about the educational system in the US?
  •  
    I tend to agree with you but I think that you are too harsh - its still only an "essay" and one of his points of making sure that education at post graduate level is not about indoctrinating what we know already is valid ...
  •  
    I think this quote by Richard Horton is relevant to the discussion: "We portray peer review to the public as a quasi-sacred process that helps to make science our most objective truth teller. But we know that the system of peer review is biased, unjust, unaccountable, incomplete, easily fixed, often insulting, usually ignorant, occasionally foolish, and frequently wrong." :P
