Scientists have made a major discovery that could reshape how post-traumatic stress disorder (PTSD) is treated. In preclinical experiments on mice, researchers identified the mechanism responsible for overwriting traumatic memories once the threat is gone—a process that, until now, was not well understood. The study revealed that dopamine, a key neurotransmitter, plays a central role […

South Korean scientists have developed a method to restore vision in degenerative retinal diseases by blocking Prox1 — a key inhibitor of regeneration in mammals. Unlike cold-blooded vertebrates, in which Müller glial (MG) cells can regenerate retinal neurons, this ability is suppressed in humans due to Prox1 activity. A study published in Nature Communications showed […

Pamela Yelick, a professor at Tufts University School of Dental Medicine, led a groundbreaking study aimed at creating living bioengineered teeth to replace lost ones. Unlike titanium implants—which lack natural sensory feedback and can cause complications—the team is working to regenerate fully functional teeth using a “

Scientists in the U.S. have successfully used pinpoint laser stimulation of the retina to evoke the perception of a previously unseen color in human vision. This new color has been named “Olo.” The experiment involved targeting specific M-cones—photoreceptor cells sensitive to medium wavelengths—without activating neighboring cells.
