    Quantum Communication: How to Outwit noise

    March 31, 2017, Categories  Physics, Technology/Electronics

    Sketch of a thermal quantum network, where two nodes (for example, two superconducting qubits located inside separated dilution refrigerators) are connected via a unidirectional quantum communication channel at finite temperature T ch . (b) For the implementation of a noise-resilient transfer protocol, the qubit state is first mapped onto an intermediary oscillator. The oscillator is then coupled to the incoming and outgoing fields of the channel, f in , i ( t ) and f out , i ( t ) , via a tunable decay rate γ i ( t ) , which can be realized, for example, by a flux-tunable quantum interference device [45, 46, 47].

    Not a Pipe Dream anymore. Space-Farming: A long legacy leading us to Mars

    March 31, 2017, Categories  Astronomy/Space, Biology/Biotechnology

    Research into space farming has resulted in numerous Earth-based advances (e.g., LED lighting for greenhouse and vertical farm applications; new seed potato propagation techniques, etc.) There are still many technical challenges, but plants and associated biological systems can and will be a major component of the systems that keep humans alive when we establish ourselves on the Moon, Mars and beyond.

    How plants are grown beyond Earth? Plants, and specifically crop plants, will be a major component of proposed regenerative life-support systems as they provide food, oxygen, scrub carbon dioxide, and aid in water recycling – all in a self-regenerating or ‘bioregenerative’ fashion...

    Solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that could have supported life billions of years ago into a frigid desert world, according to new results from NASA’s MAVEN (Mars Atmosphere and Volatile Evolution Mission) spacecraft led by the University of Colorado Boulder.

    “We’ve determined that most of the gas ever present in the Mars atmosphere has been lost to space,” said Bruce Jakosky, LASP Prof, principal investigator for MAVEN. “The team made this determination from the latest result, which reveals that about 65% of the argon that was ever in the atmosphere has been lost to space.”

    MAVEN team members had previously announced measurements showing that atmosphe...

    Beating Deadly Pneumonia with Hormones

    Borna Mehrad, MBBS (left), and Kathryn Michels, both of the University of Virginia School of Medicine, have identified a hormone that helps the body fight off the spread of bacterial pneumonia. The discovery may offer a simple way to help vulnerable patients.

    A hormone responsible for controlling iron metabolism helps fight off a severe form of bacterial pneumonia, and that discovery may offer a simple way to help vulnerable patients. Hepcidin, is produced in the liver and limits the spread of the bacteria by hiding the iron in the blood that the bacteria need to survive and grow. Stimulating hepcidin production in patients who do not produce it well, such as people with iron overload or liver disease, may help their bodies effectively starve the bacteria to death...
