Dormant cone photoreceptors in the degenerating retina may retain visual function, research suggests

New UCLA research in mice suggests that "dormant" cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity for vision.

Using tissue-embedded nanoelectronic devices to monitor the functional maturation of cardiomyocytes

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue.

Newfound mechanism helps the heart to toggle between maintenance and energy-boost mode

Researchers at the Centre for Genomic Regulation in Barcelona have discovered a mechanism involving ribosomes which helps the heart toggle between a 'regular maintenance mode' for day-to-day function and an 'energy-boost mode' which aids recovery for high-demand situations including heart attacks.
