Microsoft makes play for next wave of computing with quantum computing toolkit - 1 views

  •  
    At its Ignite conference today, Microsoft announced its moves to embrace the next big thing in computing: quantum computing. Later this year, Microsoft will release a new quantum computing programming language, with full Visual Studio integration, along with a quantum computing simulator. With these, developers will be able to both develop and debug quantum programs implementing quantum algorithms.

A Brain Built From Atomic Switches Can Learn - 0 views

  •  
    A tiny self-organized mesh full of artificial synapses recalls its experiences and can solve simple problems. Its inventors hope it points the way to devices that match the brain's energy-efficient computing prowess.

Entanglement is Necessary for Emergent Classicality in All Physical Theories - 0 views

  •  
    "...We show that any theory with a classical limit must contain entangled states, thus establishing entanglement as an inevitable feature of any theory superseding classical theory. "

Black Hole Power: How String Theory Idea Could Lead to New Thermal-Energy Harvesting Te... - 0 views

  •  
    A new class of exotic materials could find its way into next-generation technologies that efficiently convert waste heat into electrical current according to new research. Both the exotic materials and the means by which they generate electricity rely on a hybrid of advanced concepts-including string theory combined with black holes combined with cutting-edge condensed matter physics.

Vanishing star hints at direct collapse to black hole - 0 views

  •  
    The rules for a stellar death seem pretty simple. If the star isn't that massive, it burns out into a carbon-rich remnant called a white dwarf. If it's big enough, the star ends in a bang, exploding in a supernova that can leave behind a neutron star or a black hole.

New method uses heat flow to levitate variety of objects - 1 views

  •  
    Normally we associate levitation of objects to superconducting materials. Here a new technique is shown where levitation of a whole new range of materials is shown.
    "The large temperature gradient leads to a force that balances gravity and results in stable levitation," said Fung, the study's lead author. "We managed to quantify the thermophoretic force and found reasonable agreement with what is predicted by theory. This will allow us to explore the possibilities of levitating different types of objects."

    New microgravity experiments possibility?
  •  
    not really I fear .... "Typical sizes of the trapped particles are between 10 μm and 1 mm at a pressure between 1 and 10 Torr. The trapping stability is provided radially by the increasing temperature field and vertically by the transition from the free molecule to hydrodynamic behavior of thermophoresis as the particles ascend."
  •  
    Might still be OK micro to mm sized experiments.
    The technique seems to be reliable and cheap enough to compete with other types of microgravity approaches - more research needed to define boundaries of course.

First 'water-wave' laser created - 0 views

  •  
    Technion researchers have demonstrated, for the first time, that laser emissions can be created through the interaction of light and water waves, in practice mechanical oscillations in fluids at the nanoscale.
    Interesting concept on the verge of two so far different fields!

Swarm of Origami Robots Can Self Assemble Out of a Single Sheet - 5 views

  •  
    In case you are interested in Martin's past project, this article covers his master thesis. Potential for space?

    One of the biggest challenges with swarms of robots is manufacturing and deploying the swarm itself. Even if the robots are relatively small and relatively simple, you're still dealing with a whole bunch of them, and every step in building the robots or letting them loose is multiplied over the entire number of bots in the swarm.

Achieving the ultimate optical resolution by breaking Rayleigh's criterion - 1 views

  •  
    The Rayleigh criterion specifies the minimum separation between two incoherent point sources that may be resolved into distinct objects. Here, a strategy to break the limits of this criterion for the first time, some small allusion to telescopic systems.

New Boson Claim Faces Scrutiny - 0 views

  •  
    "The Atomki group has produced three previous papers on their beryllium-8 experiments - conference proceedings in 2008, 2012 and 2015. The first paper claimed evidence of a new boson of mass 12 MeV, and the second described an anomaly corresponding to a 13.45-MeV boson. (The third was a preliminary version of the Physical Review Letters paper.) The first two bumps have disappeared in the latest data, collected with an improved experimental setup. "The new claim now is [a] boson with a mass of 16.7 MeV," Naviliat-Cuncic said. "But they don't say anything about what went wrong in their previous claims and why we should not take those claims seriously." One naturally wonders, he said, "Is this value that they quote now going to change in the next four years?""
