Plants 'see' underground by channelling light to their roots - 2 views

  •  
    A light-bulb moment? Plants seem to pipe sunlight directly down into underground roots to help them grow. Light receptors in stems, leaves and flowers have long been known to regulate plant growth. Roots also have these receptors, but it has been unclear how they sense light deep in dark soil.

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.
  •  
    Can it also be applied for infrared imagery?

IBM Neuromorphic chip hits DARPA milestone and has been used to implement deep learning - 2 views

  •  
    "IBM delivered on the DARPA SyNAPSE project with a one million neuron brain-inspired processor. The chip consumes merely 70 milliwatts, and is capable of 46 billion synaptic operations per second, per watt-literally a synaptic supercomputer in your palm." --- No memristors..., yet.: https://www.technologyreview.com/s/537211/a-better-way-to-build-brain-inspired-chips/

Has a Hungarian physics lab found a fifth force of nature? - 1 views

  •  
    MTA-Atomki A laboratory experiment in Hungary has spotted an anomaly in radioactive decay that could be the signature of a previously unknown fifth fundamental force of nature, physicists say - if the finding holds up.

    Would be cool, after all the high energy physics being done to verify the SM it could be extended at the other end where nobody bothered to look ;)

First completely scalable quantum simulation of a molecule - 0 views

  •  
    A scalable quantum simulation of a molecule for the first time ever. It would finally enable practical simulation of "large" chemical systems. A research performed with Google and world class universities.

Schrödinger's Smoke - 1 views

  •  
    A team of researchers in TU berlin and Caltech used Schrödinger's equation to visualise superfluidic flow (fluids with zero viscosity). Smoke and dry ice are close to this state in nature. Strangely enough for an equation that describes subatomic particles, it works, and reproduces experimental results better that Euler and Langrange schemes.

Engineered 'sand' may help cool electronic devices - 0 views

  •  
    Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry electronic devices. The silicon dioxide doesn't do the cooling itself.

Europe plans giant billion-euro quantum technologies project - 0 views

  •  
    After graphene and blue brain, the European Commission has quietly announced plans to launch a €1-billion Euro project to boost a raft of quantum technologies - from secure communication networks to ultra-precise gravity sensors and clocks.

First evidence that sperm epigenetics affect the next generation - 0 views

  •  
    A frog study provides the strongest evidence yet that a father's lifestyle may affect the next generation, via chemical tags that change gene activity SPERM pass on more than just their DNA. Chemical switches attached to the genomes of sperm - known as epigenetic tags - have been shown to alter the next generation for the first time.

Small, cheap gravity gadget to peer underground - BBC News - 2 views

  •  
    According to their Nature article, they can detect "a tunnel less than 1m across, buried 2m underground" just from its gravitational difference. Using a device that they predict could cost ~100 € in mass production.

    UK researchers have built a small device that measures tiny fluctuations in gravity, and could be used to monitor volcanoes or search for oil. Such gravimeters already exist but compared to this postage stamp-sized gadget, they are bulky and pricy.

Bacteria's Social Media - 2 views

  •  
    Perhaps when you think of bacterial communities you think of a flask full of rapidly dividing E. coli. But in non-lab conditions, bacteria grow in complex, heterogeneous communities composed of diverse microscopic organisms. In these communities, bacteria need a means to communicate with their kin, and they do this through a language known as quorum sensing (QS), where bugs secrete and detect factors that tell them whether they're surrounded by kin (and if so, how many there are).

Nature Today | First tomatoes and peas harvested on Mars and moon soil simulant - 2 views

  •  
    Researchers from Alterra Wageningen UR were able to grow and harvest ten different crop species on Mars and moon simulant. 'The total above ground biomass produced on the Mars soil simulant was not significantly different from the potting compost we used as a control' researcher Wieger Wamelink said.

    I wonder if the taste was as disappointing as that of normal dutch veggies :P
