Bad antibodies are a major roadblock in biomedical research, harming reproducibility and wasting resources.

The International Antibody Validation Meeting was created to fix it.

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology
As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.

#Wolbachia has puzzled scientists with its power to rewire insect reproduction. What if I tell you that we found one of the keys Wolbachia use to rewire its host AND a small molecule inhibitor uses this key to mimic what this microbe has mastered for millions of years.
