NEURONAL GROWTH CONES
I spent years studying these little critters and I still do not understand them. Such is the burden that comes with choosing not to be a reductionist. Upside? Cells surprise me all the time. That has kept me coming back for 20 years.

An influenza virus infecting a single cell can produce offspring with a wide variety of shapes, maximizing the virus’s chance of escaping attack by antiviral therapies #ResearchHighlight https://t.co/8JfHkVyeNJ
Actin (red) and focal adhesions (green) in an epithelial cell acquired back when microscopes did not have automatic focusing devices. That’s right kids. We could only image one cell at a time while correcting focus drift on the fly- uphill both ways.

A hormone that muscles release in greater amounts during exercise binds to bone cells, and could help new bone cells to take the place of old ones #ResearchHighlight https://t.co/g8lTOOp1iy
A Human-Derived Antibody Targets Misfolded SOD1 and Ameliorates Motor Symptoms in Mouse Models of Amyotrophic Lateral Sclerosis https://t.co/LNV2Wgvaj3
Neurological difficulties induced by some cancer treatments might stem from nervous-system cells called microglia, which promote inflammation #ResearchHighlight https://t.co/VXUx6Fhs05
Editorial: The research community must take the lead in setting up a solid regulatory system for gene editing by creating a global registry to record preclinical research that involves gene editing in human embryos. https://t.co/Itwo0hDMTO
A device inspired by the body’s network of nerve cells could enable wireless control of artificial muscles and prostheses #ResearchHighlight https://t.co/qwnLMK55hn
Protrusion 1: Lets go this way!
Protrusion 2: No! Lets go this way!!
Protrusion 3: No! Lets go this other way!!!
Nucleus (bored): Whatever...
Golgi (shrugs): Whatever...
Protrusion 1 (to Nucleus and Golgi): Don’t be fuddy-duddies! This is exciting stuff!

POWERHOUSE AND HARD DRIVE
Watching the powerhouse of the cell - mitochondria (yellow) - can be as mesmerizing as watching a camp fire. DNA (blue) is not as fun at this timescale. Luckily there are people who can image DNA better than me.

The earliest prepared-core Palaeolithic stone tools from China are reported in a paper published in Nature. The tools date back to between 170,000 and 80,000 years ago, filling a gap in the Asian archaeological record https://t.co/uVvXZnHHuz
