Flowchart of preregistration procedure in scientific research.

Preregistration is the practice of publishing the methodology of experiments before they begin. This strategy reduces problems stemming from publication bias and selective reporting of results. See for example:

https://aspredicted.org/
https://cos.io/prereg/
https://www.psychologicalscience.org/publications/replication

A exemplary list of currently preregistered studies can be found on Zotero: https://www.zotero.org/groups/479248/osf/items/collectionKey/KEJP68G9

A CT scan providing evidence of the nasal cycle. The more patent airway is on the right of the image; the swollen turbinates congesting the left.

The nasal cycle is unknown to many people. It refers to the alternating partial congestion and decongestion of the nasal cavities in primates. It is a visible physiological congestion of the nasal conchae (nasal turbinates) due to selective lateralised activation of one half of the autonomic nervous system by the hypothalamus (cf. hemispheric lateralisation). It completly unrelated to pathological nasal congestion and is comparable to the circadian rhythm (in the broadest sense). The ancient yoga literature describes the nasal cycle in detail and it is the focus of several pranayama (breathing) techniques which have the goal to balance the nervous (...)

95% Confidence Intervals

In inferential statistics, a confidence interval (CI) is a type of interval estimate, computed from the statistics of the observed data, that might contain the true value of an unknown population parameter. The interval has an associated confidence level that, loosely speaking, quantifies the level of confidence that the parameter lies in the interval. More strictly speaking, the confidence level represents the frequency (i.e. the proportion) of possible confidence intervals that contain the true value of the unknown population parameter. In other words, if confidence intervals are constructed using a given confidence level from an infinite number of independent sample statistics, the proportion of those intervals that contain the true value of the parameter will be equal to the confidence (...)

Yoga nidrâ

becomes the bed of the lotus-naveled Vishnu when at the termination of every Yuga that deity of immeasurable power enjoys yoga-nidra, the deep sleep under the spell of spiritual meditation.
— Mahabharata, Book 1, section XXI
Yoga nidrâ (Sanskrit: योग निद्रा) also known as "yogic sleep" is a specific state of consciousness (usually induced by a guided meditation) which can be described as a a state between waking and sleeping. is an appropriate asana for yoga nidra.

The neurochemistry of altruism

A cognitive neuroscience perspective on the interpersonal dimension of psilocybin
Abstract
Psilocybin (O-phosphoryl-4-hydroxy-N,N-dimethyltryptamine) is an indole alkaloid  which is present in more than 150 fungi species, some of which are endemic to the UK (e.g., ). Its molecular structure closely resembles serotonin (5-hydroxytryptamine, 5-HT). In humans, psilocybin is rapidly dephosphorylated to psilocin (4-N,N-dimethyltryptamine) which functions as a non-selective partial 5-HT receptor agonist (it shows particularly high binding affinity for the 5-HT1A and 5-HT2A receptor subtypes; Nichols, 2004). A landmark study conducted at Johns Hopkins University by MacLean, Johnson & Griffiths (2011) experimentally demonstrated that a single high-dose of psilocybin can induce long-lasting (...)
