How Alzheimer's and Diabetes Work at the Nano-Scale

It might not seem that way because our bodies feel so unpredictable, but there is a sublime order underneath the chaos: how molecules talk to each other, what turns certain genes on and off, why some cells become blood cells and others platelets.

From Wolf to Puppy: Building the Staircase of Life

We've been genetically engineering for over 10,000 years, taking advantage of random genetic mutations and exerting human selection in the animals and plants around us. Only in the last 50 years have we developed the tools to exert greater...

From Father to Son: How Fear Changes Your DNA

Can we inherit memories? In 2014, Brian Dias and Kerry Ressler conducted an experiment to test this. They exposed male mice to an aromatic compound (acetophenone) whose receptor gene (Olfr151) had been sequenced. The mice were not born with a blank..

Transistor, Meet Neuron

Imagine a syringe with a mesh of 16 wires crumpled inside. At the end of each wire is a field-effect transistor, which can measure electrical outputs from individual neurons. The syringe narrows at the very tip to an 80µm needle, the width of a...

The Many Faces of a Neuron: Cell, Wire, and Computer

It seems that somehow, from a dense spaghetti-network of over 100 billion neurons and glial cells* that the experience of consciousness arises. Continuing from last week’s newsletter on the subjective experience of consciousness, today we look at...
