Did some reviews and…. Why do ppl show biophysical assays without the actual data? KD values with no curves or fits. An ITC table without a single raw thermogram. You wouldn’t publish a Western without the blot, but for binding assays we just say “trust me bro”. Free the curves!!

Geopickr enables particle picking on surfaces, spheres, tubes, and filaments interactively in ChimeraX!

A beach by a lake in the mountains. Blue sky, trees, pretty water. In the foreground there are the remnants of a tree trunk on its side. Roots are exposed. There are two prominent branches at 90 degrees that have another 90 degree turn in each direction to meet back up in what appears to be a natural rectanglish shape.

The text says, “I finally found it… the square root”.
