There’s a new T. rex in the fossil record, only this one terrorized the ancient seas. New research uncovers a new, massive species of mosasaur, a marine reptile that lived during the age of the dinosaurs. One of the largest mosasaurs known to date—stretching up to 43 feet long—this top predator was described from 80-million-year-old fossils that were found primarily in northern Texas decades ago. It was named Tylosaurus rex, or T. rex for short, meaning “king of the tylosaurs.”

G protein-coupled receptors sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies, from the ability to see and smell, to sensing of adrenaline, insulin, nutrients and medicines. Researchers now report using AI to create tiny, computationally designed proteins to activate or block G protein-coupled receptors. The methods used in their study may form a roadmap for future efforts to create new drug candidates for metabolic, inflammatory, and neurological diseases. These approaches would try to target G protein-coupled receptors that have been largely inaccessible to conventional drug discovery.  

Phillip Tai, PhD, received a $1.6 million grant from the National Institute of General Medical Sciences to investigate the basic mechanisms of adeno-associated viral vectors (AAV) using high-resolution DNA sequencing technology. These findings could potentially lead to new vector designs that improve the safety of gene therapy treatments.

BUFFALO, NY — May 21, 2026 — A new research paper was published in Volume 13 of Oncoscience on April 2, 2026, titled “Selective blood–brain barrier penetration and tumor targeting of nitrosylcobalamin in glioblastoma: Pharmacokinetics, tissue distribution, and synergistic activity with trail and temozolomide.”

Vitamin K has long been linked to bone health, but its precise role remained unclear. A new study shows that vitamin K-dependent γ-carboxylation in osteoblasts regulates bone breakdown through the signaling protein, GAS6. In male mice, blocking this pathway increased bone mass by reducing osteoclast formation, while elevated GAS6 enhanced bone resorption. The findings uncover a previously unknown communication pathway between osteoblasts and osteoclasts, offering insights into osteoporosis and future skeletal therapies.
