Instead of talking about the predatory nature of MDPI journals, can we talk
about how UGLY their formatting is? It’s literally hurting my eyes reading their
papers online and PDFs 😣

Finalnd downgraded many MDPI and Frontiers journals in their quality grading.
Good call for MDPI. As for Frontiers I am not really sure but tend to say its
also a good call. 🧪 🛟

Interesting new mutation identified in the SCN9A gene, which leads to
nociceptive deficiency (not “insensitivity to pain” 🤦🏻‍♂️). This gene encodes
for the Nav1.7 sodium gated channel.

Since an academic douche bothered to mock at this: Why do my colleagues and I
call the nociceptive section of the nervous system, an apparatus, and not a
”system”? Chat GPT gives a very good answer here.
