Every few seconds, we blink our eyes — a simple, involuntary act. While it’s commonly understood that blinking keeps our eyes lubricated, a new study by researchers from the University of Rochester has uncovered a more intricate role: blinking also helps our brains process visual information more effectively. Published in the Proceedings of the National Academy of Sciences, the study sheds light on how these brief closures of our eyes contribute to visual perception.

Scientists have discovered a previously unknown function of blinking

Researchers at St. Jude Children’s Research Hospital and the University of Minnesota have discovered that the aging of T-cells is not constrained by the age of the organism, enabling these healthy cells to continue multiplying indefinitely. Most cell types undergo functional decline after extensive proliferation and replication over the...

Mental maps play a crucial role as you navigate your daily route to work or the grocery store. These cognitive maps, stored in your hippocampus and entorhinal cortex, retain information about paths you’ve taken and locations you’ve visited, enabling you to find your way effortlessly. But what happens when you only think about a location?

Mental maps help the brain remember places and paths

Researchers at the University of Rochester have made groundbreaking advancements in our understanding of color perception. In a recent study published in the Journal of Neuroscience, they identified rare retinal ganglion cells (RGCs) that could fill critical gaps in our knowledge of how we see colors. These findings indicate that, in addition to the established color detection pathways followed by most RGCs, a small number of these non-conventional cells may play an important role in color vision.

We’re all forgetful from time to time, but for some of us, forgetfulness is a real problem. From little things like items on our grocery list to bigger things like important work meetings or anniversaries, the tendency to forget is not only annoying, but it can be detrimental to our relationships, work, and general ability to function well in a structured, fast-paced society.

Review the multiple uses of metformin. A recent article on the multiple uses of metformin brings up the important topic of repurposing medications.1 Repurposing has been around since the advent of modern medicine. One prominent example is the use of chlorpromazine (CPZ) as an antipsychotic.2 Chlorpromazine was first synthesized in 1951 as a potentiator of general anesthesia.2 The psychiatric benefits were found later by Henri Laborit, a surgeon in the French army. He was doing research with artificial hibernation in prevention of surgical shock.2 Laborit employed the drug as an adjunct to anesthetics.2 He observed that CPZ at doses of 50 mg to 100 mg produced a lowering of body temperature, sedation, and disinterest without loss of consciousness.2 He was able to persuade his colleagues in the military hospital in Paris to try CPZ in the treatment of one of their patients who was experiencing psychotic agitation.2 Laborit hypothesized that since cooling with water had been used to treat agitation in France, the drug would have a similar effect.2 The mechanism of action was not fully known, and it was thought that it worked in controlling agitation because of its cooling effect and induction of “artificial hibernation” in patients.2 The pharmacological mechanism was not fully understood until many years later and the way it has impacted the practice of psychiatry needs no introduction. These “happy accidents” in medicine have played a vital role in getting where we are right now compared with just 50 years ago. This begs the question, are we onto another “happy accident” with metformin? There is an accumulating body of evidence that metformin may have benefits in aging that are beyond its effect on glycemic control.3.
