Researchers discover why cold induces tooth pain and hypersensitivity — and how to stop it

Researchers report in Science Advances that they have uncovered a new function for odontoblasts, the cells that form dentin, the shell beneath the tooth’s enamel that encases the soft dental pulp containing nerves and blood vessels. “We found that odontoblasts, which support the shape of the tooth, are also responsible for sensing cold,” says pathologist Jochen Lennerz, MD, PhD, one of the paper’s senior authors and medical director of the Center for Integrated Diagnostics at Massachusetts General Hospital (MGH). “This research contributes a new function to this cell, which is exciting from a basic-science standpoint. But we now also know how to interfere with this cold-sensing function to inhibit dental pain.”

Scientists detect MORE THAN 50 chemicals from everyday products in pregnant women and newborns

American scientists have detected more than a hundred chemicals in the blood of pregnant women and their children. Fifty-five of these substances had not been found in humans before, while 42 “mystery chemicals” had no sources or known uses. Based on their findings, the scientists posited that the children receive the chemicals through the mother’s placenta while still in the womb.

Ubisoft Making The Next Generation Of NFT Games

Ubisoft has since continued on in the space by working closely with crypto gaming startups and releasing its own small-scale experiments.
