The Baeyer-Villiger Monooxygenases (BVMOs) are enzymes belonging to the "Class B" of flavin monooxygenases and are capable of performing exquisite selective oxidations.These enzymes have been studied from a biotechnological perspective, but their physiological substrates and functional roles are widely unknown.Here, we investigated the origin, taxo
One of the goals of current particle physics research is to obtain evidence for new physics, that is, physics beyond the Standard Model (BSM), at accelerators such as the Large Hadron Collider (LHC) at CERN.The searches for new physics are often guided by BSM theories that depend on many unknown parameters, which, in some cases, makes testing their
