To Sleep, Perchance to Clean - University of Rochester Medical Center - 2 views

  •  
    Why do we sleep? One answer could be: to clear waste products accumulated during the day. To prevent aging and neurodegeneration, the body must maintain homeostasis. What would happen if we experience chronic sleep loss? What would happen if microgravity impairs the cerebrospinal fluid to flush the brain? What would happen if cosmic radiations increase the amount of daily waste products?

Intrinsic functional connectivity reduces after first-time exposure to short-term gravi... - 0 views

  •  
    Loss of connectivity in the multisensory integration cortical areas after short term microgravity experience, which could explain astronauts decrease of performance in sensorimotor tasks and spatial working memory. However, the effect should wear off after a few days in microgravity and after adaptation to incongruent vestibular information. ISS experiment needed...

    Cyano bacteria to shield from radiation. An idea from italians flying to the Moon via Team Indus
  •  
    Nice idea, but is it really new: resistance of cyanob. to UV radiation has been known but studies have been inconclusive as to under what resource limitations it works, but according to what we see from evolution: on Earth it works, since they survived pre-ozone atmosphere!

    some papers from a quick google search:

Fiji ants farm plants, study shows - 1 views

  •  
    Ants found in the Pacific islands of Fiji behave as miniature farmers, carefully sowing and fertilising the seeds of at least six types of plant, a study said Monday.

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.

Gene name errors are widespread in the scientific literature - 0 views

  •  
    The spreadsheet software Microsoft Excel, when used with default settings, is known to convert gene names to dates and floating-point numbers. A programmatic scan of leading genomics journals reveals that approximately one-fifth of papers with supplementary Excel gene lists contain erroneous gene name conversions.

    The reason why you shouldn't use Excel (or Numbers or OpenOffice or ...) without knowing what it actually really does!

MIT's Invisible Second Skin Cream Makes Wrinkles Disappear - 0 views

  •  
    "Applications for the film extend beyond getting rid of wrinkles, though. It can safely deliver medications for 24 hours at a time as well as protect the user's skin, particularly over wounds. Additionally, the XLP material can reduce moisture loss. "

The Cure For Fear | New Republic - 2 views

  •  
    A long read but very interesting and well written.
  •  
    PS: Does this quote from the article not sound a lot like Inception?
    'In any given situation, the brain will retrieve old memories to inform an organism's behavior. If the memory is relevant to the situation, the organism can act on the information; if it is not relevant, then the organism can learn from the situation and create a new memory. With reconsolidation, researchers argued, there seemed to be a brief window in between the retrieval of an old memory and the creation of a new memory in which the old memory is vulnerable to manipulation.'

Breakthrough method means CRISPR just got a lot more relevant to human health - 0 views

  •  
    "scientists at Harvard University say they've modified the CRISPR method so it can be used to effectively reverse mutations involving changes in one letter of the genetic code. That's important because two-thirds of genetic illness in humans involve mutations where there's a change in a single letter."

    "Efficient introduction of specific homozygous and heterozygous mutations using CRISPR/Cas9" http://www.nature.com/nature/journal/vaop/ncurrent/full/nature17664.html?WT.ec_id=NATURE-20160428&spMailingID=51249830&spUserID=MTEzODM0NjYzMzgS1&spJobID=903461217&spReportId=OTAzNDYxMjE3S0

    As posted here previously, the number and importance of CRISPR is growing steadily, but still plenty of work to make it a reliable tool.
    Maybe, next work for the Molecular Engineering RF?

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.

Clothes that receive and transmit digital information are closer to reality - 1 views

  •  
    Hard work in functional materials is driving the development of new wearable electronics that could be advantageous for communications and sensing is being pursued in the Advanced Functional Fabrics of America Institute. Through embroidering circuits into fabric with 0.1 mm precision full integration of electronic components such as sensors and computer memory devices into clothing is now possible.
