Was a metamaterial lurking in the primordial universe? - physicsworld.com - 1 views

  •  
    A scientist in the US is arguing that the vacuum should behave as a metamaterial at high magnetic fields. Such magnetic fields were probably present in the early universe, and therefore he suggests that it may be possible to test the prediction by observing the cosmic microwave background (CMB) radiation - a relic of the early universe that can be observed today.

Getting to the froth of the matter - physicsworld.com - 1 views

  •  
    Whether it is the frothy milk on your cappuccino, the soapy suds in your bath or the large-scale structure of the universe, foams have intrigued physicists for many years. Now, for the first time in a lab, an international group of scientists has made the Weaire-Phelan foam - which physicists believe is the lowest-energy structure for a foam formed of equal-volume bubbles.
  •  
    Does this mean that there is foam that is non regular that can have even less energy structure? "which physicists believe is the lowest-energy structure for a foam formed of equal-volume bubbles."

Fur and feathers keep animals warm by scattering light - 1 views

  •  
    In work that has major implications for improving the performance of building insulation, scientists at the University of Namur in Belgium and the University of Hassan I in Morocco have calculated that hairs that reflect infrared light may contribute significant insulating power to the exceptionally warm winter coats of polar bears and other animals.
  •  
    That's quite interesting. Maybe the future of buildings and spacecraft is furry?

'Sixth sense' really exists, scientists say - 1 views

  •  
    New research reveals that humans utilize a part of the brain that is organized topographically to determine, for example, the number of jelly beans in a bowl or the number of cookies in a jar.

The future of the great barrier reef - 1 views

  •  
    A worrying future looms as scientist predict the iconic great barrier reef is at a turning point and could experience irreversible damage before 2030 if nothing is done right now. Well actually, I am not sure if anything can be done as the two degree rise (and changes in ocean temperature/acidity probably?) will likely happen in any case due to delayed effects of decades of pollution, whether or not we stop now with emissions will probably not make much difference. :(

Have Harvard Scientists Created A Real Lightsaber? Kind Of. - 0 views

  •  
    A joint Harvard-MIT research program led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic has created a new state of matter the two describe as extremely similar to the lightsabers seen in "Star Wars."

Polymer scientists jam nanoparticles, trapping liquids in useful shapes - 1 views

  •  
    Inserting a droplet of polymer enriched water into oil and manipulating its shape by applying an electric field. The shape remains intact after cease of the forcing. <br /> "Russell (...) points out that the advance holds promise for a wide range of different applications including in drug delivery, biosensing, fluidics, photovoltaics, encapsulation and bicontinuous media for energy applications and separations media."

Quantum computer around the corner after Australian scientists make key breakthrough - 1 views

  •  
    Australian scientists have cleared one of the final hurdles for designing and building a quantum computer. The team of engineers from the University of New South Wales has successfully built a core component needed for the computer to operate and the work is published today in the journal Nature.

Data scientists find connections between birth month and health - 4 views

  •  
    Seems like astrologists were somehow right... Ptolemy would be proud.
  •  
    Greetings from July :-) On an unrelated note... this chart made me suddenly realise I've been always thinking of the year as passing counter-clockwise and starting at the bottom. Very strongly. Seems like some tempo-spatial association. Anybody has a similar feeling?

Italian scientists claim to have demonstrated cold fusion (w/ Video) - 3 views

  •  
    mah...
  •  
    Perhaps they measured the "cold fusion" of Berlusconi with his girls. But that's not that cold, as it seems...
  •  
    ...that is definitely HOT... ...on the other hand I don't think it would be fusion since it does not seems to produce any bound state... double mystery :)

Six rules for nano-design - physicsworld.com - 1 views

  •  
    a group of scientists in the US has formulated a set of basic rules that could help understanding how particles interact at the nanoscale
  •  
    The most trivial application is to triple the bandwidth capability of an antenna.... working on some more exotic stuff...

Ergodic theorem passes the test - physicsworld.com - 0 views

  •  
    For more than a century scientists have relied on the "ergodic theorem" to explain diffusive processes such as the movement of molecules in a liquid. However, they had not been able to confirm experimentally a central tenet of the theorem - that the average of repeated measurements of the random motion of an individual molecule is the same as the random motion of the entire ensemble of those molecules. Now, however, researchers in Germany have measured both parameters in the same system - making them the first to confirm experimentally that the ergodic theorem applies to diffusion.

Quantum biology: Algae evolved to switch quantum coherence on and off -- ScienceDaily - 3 views

  •  
    Scientists have discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to advances such as better organic solar cells.
  •  
    very very nice! we tried already a few years back to find an angle to see how we could study quantum phenomena occuring in plants and photosynthsis is one of the great examples since somehow plants manage to make the phenomena work for them at elevated temperatures, a feat in itself ... any good idea most welcome!!!
