Citizen science: Eyewire discovers 6 new types of neurons - 4 views

Here is a the publication in Cell Journal (>29,000 coauthors): https://doi.org/10.1016/j.cell.2018.04.040 ...and I am a coauthor, because I played it while in the ACT! Lol

Does the brain store information in discrete or analog form? - 1 views

  •  
    "...measured the way people make certain types of decisions and say that their statistical analysis of the results strongly suggests that the brain must store information in discrete form. Their conclusion has significant implications for neuroscientists and other researchers building devices to connect to the brain."

Scientists to grow 'mini-brains' using Neanderthal DNA - 3 views

  •  
    Scientists are preparing to create "miniature brains" that have been genetically engineered to contain Neanderthal DNA, in an unprecedented attempt to understand how humans differ from our closest relatives.

The innovation turning desert sand into farmland - 1 views

  •  
    Norwegian scientist Kristian Morten Olesen has patented a process to mix nano-particles of clay with water and bind them to sand particles to condition desert soil - he has been working on Liquid Nanoclay (LNC) since 2005.
  •  
    The news here that some patent has been filed. If it actually works the guy is an ass for wanting to patent something that is solving world hunger. If it does not, then the guy is still an ass. So the news is that this guy is an ass :)
  •  
    Agreed :) But, if it does work I doubt the guy will be able to enforce the patent in most of the countries where this will be helpful.

Is the staggeringly profitable business of scientific publishing bad for science? | Sci... - 2 views

  •  
    "Publishing industry exerts too much influence over what scientists choose to study, which is ultimately bad for science itself"
  •  
    On a related topic - a nice read written in 1939 from Abraham Flexner the founder of Institute for Advanced Study in Princeton, home of some great minds on the "Usefulness of Useless Knowledge". Enjoy

    This article is fantastic - starts already well with : "r

    IT not a curious fact that in a world steeped in irrational hatreds which threaten civilization itself, men and women-old and young-detach them-selves wholly or partly from the angry current of daily life to devote themselves to the cultivation ofbeauty, to the exten-sion ofknowledge, to the cure ofdisease, to the amelioration of suffering, just as though fanatics were not simultaneously engaged in spreading pain, ugliness, and suffering?"

Vacuum tubes are back - in nano form - 0 views

  •  
    Although vacuum tubes were the basic components of early electronic devices, by the 1970s they were almost entirely replaced by semiconductor transistors. They are now back in nano-form as "nanoscale vacuum channel transistors" that combine the best of vacuum tubes and modern semiconductors into a single device.

    This old-technology with a new twist could be useful for space applications due to broader temperature operational range and better radiation resilience - authors are with NASA Ames.

Calling Bullshit - 2 views

  •  
    A college course at University of Washington on "Calling Bullshit". We should invite them to give a lunch lecture at ESA...

    Our aim in this course is to teach you how to think critically about the data and models that constitute evidence in the social and natural sciences.

    While bullshit may reach its apogee in the political domain, this is not a course on political bullshit. Instead, we will focus on bullshit that comes clad in the trappings of scholarly discourse.

    Our learning objectives are straightforward. After taking the course, you should be able to:

    * Remain vigilant for bullshit contaminating your information diet.
    * Recognize said bullshit whenever and wherever you encounter it.
    * Figure out for yourself precisely why a particular bit of bullshit is bullshit.
    * Provide a statistician or fellow scientist with a technical explanation of why a claim is bullshit.
    * Provide your crystals-and-homeopathy aunt or casually racist uncle with an accessible and persuasive explanation of why a claim is bullshit.

    We will be astonished if these skills do not turn out to be among the most useful and most broadly applicable of those that you acquire during the course of your college education.
  •  
    love it:
    "Politicians are unconstrained by facts. Science is conducted by press release. Higher education rewards bullshit over analytic thought. Startup culture elevates bullshit to high art. Advertisers wink conspiratorially and invite us to join them in seeing through all the bullshit - and take advantage of our lowered guard to bombard us with bullshit of the second order. The majority of administrative activity, whether in private business or the public sphere, seems to be little more than a sophisticated exercise in the combinatorial reassembly of bullshit.

    We're sick of it. It's time to do something, and as educators, one constructive thing we know how to do is to teach people. So, the aim of this course is to help students navigate the bullshit-rich modern environment by identifying bullshit, seeing through it, and combating it with effective analysis and argument."

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.

Proof of the Riemann Hypothesis utilizing the theory of Alternative Facts - 0 views

  •  
    An excellent science coffee topic! This is a true breakthrough in pure mathematics with plentiful applications in the lesser sciences (such as theoretical physics). People tell me quantum gravity is already practically solved by this.

    Conway's powerful theory of Alternative Facts can render many difficult problems tractable. Here we demonstrate the power of AF to prove the Riemann Hypothesis, one of the most important unsolved problems in mathematics. We further suggest applications of AF to other challenging unsolved problems such as the zero-equals-one conjecture (which is also true) and the side-counting problem of the circle.
