Young biologists should work on plants. 🌱
1. SynBio tools are ~10 yrs behind bacteria
2. Basic science has lagged. Often, we don't know what to edit to improve traits
3. Pesticide use is flat & 40% of crops lost to pests
5. Design flowers.
Lots of room to make a big impact!

Powering the cell's biochemical reactions is no easy job. We bring this amazing orchestra to life so you can truly understand and appreciate this little powerhouse organelle - the mitochondrion. #morethanjustapeanut #mitochondria #3Dbiology #glycolysis

We have 3 space dimensions but only one dimension of time. Why is there just one time? What would happen if there were more time dimensions?
A short 🧵that requires some math. (You can probably follow w/o math as well) 1/16

A Pandemic Test-Ban Treaty would ban the experimental tests needed to learn which viruses are pandemic-capable. Rogue actors can't perform these and be believed because the results are easy to fake. Only the well-meaning can share credible blueprints for plagues.
