Visualizing fields of research based on readership

by Peter Kraker in Science and the Web (Peter Kraker's weblog)

Social reference management systems provide a wealth of information that can be used for the analysis of science. In this paper, we examine whether user library statistics can produce meaningful results with regards to science evaluation and knowledge domain visualization. We are conducting two empirical studies, using a sample of library data from Mendeley, the worlds largest social reference management system. Based on the occurrence of references in users libraries, we perform a large-scale i........ Read more »

Visualizing fields of research based on readership

by Peter Kraker in Science and the Web

I haven’t blogged lately, mostly due to the fact that I was busy moving to London. I will be with Mendeley for the next four months in the context of the Marie Curie project TEAM. My first week is over now, and I have already started to settle in thanks to the great folks at …Read More... Read more »

Advances in Neuronal Destruction

by TheCellularScale in The Cellular Scale

Destroying neurons is not difficult.  Destroying specific neurons, but leaving others intact is another story. Ablating specific neurons usually involves fancy genetic trickery, but it can also be accomplished with fancy mechanical lasers! Laser near cell (source)A new study published in PNAS (Hayes et al., 2012) uses the cells own rhythm generating properties to target the neurons for destruction.Specifically, Hayes et al. is investigating the breathing neurons. These neurons are in t........ Read more »

Artificial Cerebellum in Robotics Developed

by Jason Carr in Wired Cosmos

University of Granada researchers have developed an artificial cerebellum (a biologically-inspired adaptive microcircuit) that controls a robotic arm with human-like precision. The cerebellum is the part of the human brain that controls the locomotor system and coordinates body movements.... Read more »

Is Chaitin proving Darwin with metabiology?

by Artem Kaznatcheev in Evolutionary Games Group

Algorithmic information theory (AIT) allows us to study the inherent structure of objects, and qualify some as ‘random’ without reference to a generating distribution. The theory originated when Ray Solomonoff (1960), Andrey Kolmogorov (1965), and Gregory Chaitin (1966) looked at probability, statistics, and information through the algorithmic lens. Now the theory has become a central [...]... Read more »

Herkent u deze melodie? [Dutch]

by Henkjan Honing in Music Matters

Je zit in je auto en draait wat aan de knop van de radio. Je hoort al snel of bepaalde muziek je bevalt of niet. Je herkent een stem, een liedje of zelfs de uitvoering ervan. Iedereen doet het, iedereen kan het. En vaak ook nog eens razendsnel: sneller dan een noot gemiddeld klinkt.Als u gevraagd zou worden om naar een reeks muziekfragmenten van 0,2 seconde te luisteren, zal blijken dat u met gemak aan kan geven welk fragment klassiek, jazz, R&B of pop is (zie luistertest). Een snippertje ge........ Read more »

Why does a well-tuned modern piano not sound out-of tune?

by Henkjan Honing in Music Matters

Karlheinz Stockhausen is listening."Neue Musik ist anstrengend", wrote Die Zeit some time ago: "Der seit Pythagoras’ Zeiten unternommene Versuch, angenehme musikalische Klänge auf ganzzahlige Frequenzverhältnisse der Töne zurückzuführen, ist schon mathematisch zum Scheitern verurteilt. Außereuropäische Kulturen beweisen schließlich, dass unsere westliche Tonskala genauso wenig naturgegeben ist wie eine auf Dur und Moll beruhende Harmonik: Die indonesische Gamelan-Musik und Indiens Raga........

Neuron-controlled robots: reverse-cyborgs

by TheCellularScale in The Cellular Scale

Last post we discussed robotically controlled biology.  In this post we will talk about biologically controlled robots.The Hybrot: a rat neuron controlled robotIn 2001, S. Potter published a paper on the "Animat". A set of cultured neurons on a multi-electrode array (MEA, purple circle in above image) interfaced with a simulated robot.  That is, not a physical moving around robot as pictured above, but a computer program simulating what a robot/animal could do.  They made a v........

The Evolution of Music

by Iddo Friedberg in Byte Size Biology


A collaboration between a group in Imperial College and Media Interaction group in Japan yielded a really cool website: darwintunes.org. The idea is to apply Darwinian-like selection to music. Starting form a garble, after several generations producing something that is actually melodic and listen-able. Or a Katy Perry tune. Whatever. The selective force being the appeal of the tune to the listener. ... Read more »

Can artificial music evolve in a Darwinian way?

by Henkjan Honing in Music Matters

This week an interesting study appeared in PNAS (early edition) showing that a simple Darwinian process can produce music. Inspired by cultural transmission theory, the study suggests that the evolution of music can be viewed and analyzed in terms of selection-variation processes, and, as such, may shed light on the evolution of real musical cultures. ...

Remote-controlled cyborg insects

by TheCellularScale in The Cellular Scale

Cyborgs capture the imagination. Whether human-machine prosthetics or machine-insect spybots, the possibilities for medical advances and for exciting sci-fi novels are virtually endless. Remote controlled beetle from 1909 from Insect Lab A paper in 2009 by Sato et al. made some significant advances in the frontier of remote-controlled cyborg beetles. Specifically they were able to stimulate relatively specific neurons in these beetles to get them to initiate flight........ Read more »
