Scientists discovered why Roman buildings have survived so long. It's because they included an ingredient in their concrete – once thought to be from shoddy mixing – that helps the concrete self-heal as it cracks over time. The discovery may help future concrete mixes become self-healing and last longer.

A mini review on how metaplasticity model can be useful for understanding cross-modal plasticity.

I'd have to thank Dr. Leon Cooper for developing the BCM sliding threshold model back in the 80's. I continues to amaze me that the BCM model can elegantly explain cortical plasticity.

Opinion: Here are two changes that would help make NIH grant peer review more fair, consistent, and efficient
We don’t need a redesign of the NIH grant review system. We can, however, improve matters with key adjustments implemented easily and at minimal cost. https://www.pnas.org/doi/10.1073/pnas.2214028119

In Alaska, wood frogs freeze for seven months, thaw and hop away.

@wonderofscience Remember Carl's words here. As true now as they have ever been.

The human cochlea has about 30,000 nerve fibers connecting to the brain, so when rounding to the nearest approximate power of 2 one can argue that The vOICe is equivalent to a 2x 32,000 electrode brain implant with an 80+ year longevity https://en.wikipedia.org/wiki/Cochlear_nerve #auditory #neuroscience; now we just need a bit of functional rewiring through #crossmodal #plasticity

Cognitive Biases and Brain Biology Help Explain Why Facts don’t Change Minds
Facts First
Once facts are established, opinions can be formed.
Problem is that while it sounds logical, It is a fallacy not supported by #research
#Cognitive #psychology and #neuroscience studies found that people form opinions based on emotions, such as fear, contempt and anger, rather than relying on facts.
Facts often do not change people’s minds.

(1/3) Neuronal reactivation and replay in the #hippocampus is important for #learning and #memory. So does reactivation induce or modulate synaptic plasticity? We think it does! This is a video abstract made with #blender of our recent paper in #elife.

My argument, at its core, is that to do that, we need to teach people why science deserves their trust – and this requires teaching how science works as a social institution. I've written about this in brief in a Science American article: https://www.scientificamerican.com/article/to-fight-misinformation-we-need-to-teach-that-science-is-dynamic/

Good morning #mastodon !
Incredible what you can see at night in the right part of the world, at the right time
The universe is just so vast and we see so little of it, but what we do see is amazing, we are both irrelevant and the center of it all
Are we alone or not?

This map shows only people. It is a beautiful illustration of where people are concentrated.
If you squint, you can see Australia and New Zealand.
