The Complexities of “The Love Hormone”

by Miss Behavior in The Scorpion and the Frog

New York street art. Photo inWikimedia Commons posted by Pedroalmovar.Oxytocin, commonly known as “the love hormone”, is a small chemical that is produced in the brain of mammals, but can both act as a neurotransmitter and enter the blood stream and act as a hormone. It has long been heralded for its role in both maternal and romantic love, but more recent research is showing us just how complicated the physiology of love can be.Oxytocin is released in mammalian mothers after birth. It promo........ Read more »

Scientific reliability and the role of theory

by Multiple Authors in EPPI-Centre blog

The replication crisis, publication bias, p-hacking, harking, bad incentives, undesirable pressures and probably other factors all contribute to diminish the trustworthiness of published research, with obvious implications for research synthesis. Sergio Graziosi asks whether demanding simple theoretical clarity might be part of the solution.

Biofouling successional processes

by SciELO in SciELO in Perspective | Press Releases

To assess the successional pattern of fouling organisms we tested the hypothesis that depth, light intensity and predation influences the trajectory of the fouling community. The results suggest that each physical factor or biological process can change the successional trajectory, and the respective model (e.g., convergent, divergent, parallel, or cyclic) depends on the magnitudes of the determinants that act on the community at each stage of its trajectory. … Read More →...

Preprints – the way forward for rapid and open knowledge sharing

by SciELO in SciELO in Perspective

Preprints – versions of academic articles that have not yet been formally peer-reviewed before publication – are gaining acceptance in the academic world. They deliver open access as well as speedy publication, and their decades old success in physics has spurred on their spread in other disciplines. The development of preprints is accelerating; important funding agencies are in support of them, and also SciELO is planning to set up a preprint server for authors in Latin America and the Glob........

Crowdfunding and Tribefunding in Science

by Jalees Rehman in The Next Regeneration

Competition for government research grants to fund scientific research remains fierce in the United States. The budget of the National Institutes of Health (NIH), which constitute the major source of funding for US biological and medical research, has been increased only modestly during the past decade but it is not even keeping up with inflation. This problem is compounded by the fact that more scientists are applying for grants now than one or two decades ago, forcing the NIH to enforce strict........ Read more »

Nature Shapes Faithful and Unfaithful Brains

by Miss Behavior in The Scorpion and the Frog

Among monogamous animals, some individuals are more faithful than others. Could these differences in fidelity be, in part, because of differences in our brains? And if so, why does this diversity in brain and behavior exist?A snuggly prairie vole family.

Two Manifestos for Better Science

by Neuroskeptic in Neuroskeptic_Discover



Two new papers outline urge scientists to make research more reproducible.



First off, Russ Poldrack and colleagues writing in Nature Reviews Neuroscience discuss how to achieve transparent and reproducible neuroimaging research. Neuroimaging techniques, such as fMRI, are enormously powerful tools for neuroscientists but, Poldrack et al. say, they are at risk of "a ‘perfect storm’ of irreproducible results". because the "high dimensionality of fMRI data, the relatively low power of mos...
