Lotka-Volterra, replicator dynamics, and stag hunting bacteria

by Artem Kaznatcheev in Evolutionary Games Group

Happy year of the monkey! Last time in the Petri dish, I considered the replicator dynamics between type-A and type-B cells abstractly. In the comments, Arne Traulsen pointed me to Li et al. (2015): We have attempted something similar in spirit with bacteria. Looking at frequencies alone, it looked like coordination. But taking into account […]... Read more »

Brain power: Wirelessly supplying power to the brain

by Dr. Jekyll in Lunatic Laboratories

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

How language changes the way you hear music

by Richard Kunert in Brain's Idea

In a new paper I, together with Roel Willems and Peter Hagoort, show that music and language are tightly coupled in the brain. Get the gist in a 180 second youtube clip and then try out what my participants did. The task my participants had to do might sound very abstract to you, so let […]... Read more »

WATCH: Cockroach-Inspired Robots Could Save You

by Jenny Ludmer in Rooster's Report

The fear of cockroaches is so common there’s a name for it, katsaridaphobia. And yet, there are apparently scientists out there with nerves of steal. By working with these creepy critters, they’ve actually created a roach-inspired robot. Just like the real thing, it can slither through tiny cracks, and if it doesn’t scare the dickens out of you, it might just save your life one day.... Read more »

New research challenges the idea that women have more elaborate autobiographical memories than men 

by BPS Research Digest in BPS Research Digest

The longest autobiographical narratives were produced by men talking to women Prior research has found that women elaborate more than men when talking about their autobiographical memories, going into more detail, mentioning more emotions and providing more interpretation. One problem with this research, though, is that it hasn't paid much attention to who is listening or whether the memories are spoken or written.This is unfortunate because findings like these can fuel overly sim........

Baby can see, what an adult can’t

by Usman Paracha in SayPeople

Main Point:

Babies have an unusual ability to see those things and differences in pictures that are not visible to adults.

Published in:

Current Biology

Study Further:

In a study conducted by researchers from Japan, it has been reported that infants under 5 months of age have an ability to detect changes in pictures or images that are not visible to adults. However, this ability disappears rapidly, and infants in the age range of 5 months to 6 months are unable to detect image dif........ Read more »

Decreased brain levels of vitamin B12 in autism

by Paul Whiteley in Questioning Answers

I have to thank Dr Malav Trivedi for bringing my attention to some recent findings reported by Yiting Zhang and colleagues (including Malav) [1] (open-access) suggesting that: "levels of vitamin B12, especially its MeCbl [methylcobalamin] form, decrease with age in frontal cortex of control human subjects."Further, researchers reported: "abnormally lower total Cbl [cobalamin] and MeCbl levels in subjects with autism and schizophrenia, as compared to age-matched cont........
