Yale University researchers have unveiled significant findings across various scientific fields, including concerns over online access to weight-loss drugs and new insights into evolutionary biology and quantum mechanics.

A study revealed that 92% of 49 websites advertising GLP-1 weight-loss drugs provided prescriptions to a "secret shopper" with minimal direct clinician interaction. Reshma Ramachandran, co-director of the Yale Collaboration for Regulatory Rigor, Integrity, and Transparency, said, "[They] need to have protections in place that are more robust." This highlights a lack of oversight in online pharmaceutical access.

Separately, Yale researchers are challenging a long-held theory regarding the evolution of warm-blooded predators like tuna. The theory suggested that the asteroid impact which killed the dinosaurs created conditions spurring tuna evolution, but new findings indicate this theory "doesn't quite hold water."

Furthermore, Yale physicists have developed a "user manual" for Fermi's "Golden Rule," a fundamental quantum mechanical formula often misapplied despite underpinning many modern technologies. This blueprint aims to improve its accurate application in experiments and theoretical work.
