New Discovery turns Neuroscience Upsidedown
Sometimes finding out that something established isn’t true is more groundbreaking than finding something new. That is exactly what happened this week when it was found out that the covering that […]

Was Lamarck right after all? A look at epigenetic inheritance
Myths © EEGFrom the Wikipedia definition of epigenetics: "In biology, and specifically genetics, epigenetics is the study of heritable changes in gene activity that are not caused by changes in the DNA sequence."Wait a minute... how can we inherit anything that's not encoded in the DNA? All the information we inherit from our parents is coded in the DNA ... Right?That's correct. However, there's something very important that goes hand in hand with the information contained in the genes: […]

The Mystery of “Quantum Resonance Spectroscopy”
Can quantum physics help to diagnose schizophrenia and depression? A paper just published in the Journal of Nervous and Mental Disease claims that a technique called ‘quantum resonance spectroscopy’ (QRS) can accurately diagnose various mental health problems. But is it quantum wizardry or magic quackery? According to the authors of the new paper, Zhang et […]The post The Mystery of “Quantum Resonance Spectroscopy” appeared first on Neuroskeptic.

The nose knows: How to pick your friends
We all have that friend. Let's call her Jane. Jane is bubbly and gregarious. Jane doesn't attend a party, she manifests it. She seeks out social gatherings and is enlivened by human presence. Jane is a good listener and has many trusted friends. What can explain Jane's extroversion? The answer, astonishingly, is her attraction to human body odor.

Monotonicity of EM Algorithm Proof
Here the monotonicity of the EM algorithm is established. $$ f_{o}(Y_{o}|\theta)=f_{o,m}(Y_{o},Y_{m}|\theta)/f_{m|o}(Y_{m}|Y_{o},\theta)$$ $$ \log L_{o}(\theta)=\log L_{o,m}(\theta)-\log f_{m|o}(Y_{m}|Y_{o},\theta) \label{eq:loglikelihood} $$ where \( L_{o}(\theta)\) is the likelihood under the observed data and \(L_{o,m}(\theta)\) is the likelihood under the complete data. Taking the expectation of the second line with respect to the conditional distribution of \(Y_{m}\) given \(Y_{o}\) and […]

Typing Method for Cryptosporidium Meleagridis
We recently developed a highly applicable method for typing of Cryptosporidium meleagridis isolates. C. meleagridis is the third most common species involved in human cryptosporidiosis, a dirrhoeal disease taking a major toll on global health. Molecular typing of Cryptosporidium is critical to understanding transmission and identifying outbreaks. Until now, no robust method has been available […]
