New Insights into Cellular Regeneration Through Gap Closure Study

The National Institute of General Medical Sciences, a branch of the National Institutes of Health (NIH), has awarded Yubing Sun, associate professor of mechanical and industrial engineering at the University of Massachusetts Amherst, a $1.9 million Maximizing Investigators' Research Award to support the exploration of the fundamental principles behind the process that close gaps caused by injury or growth between cells.

Researchers Uncover Role of OpgH in Bacterial Cell Shape

In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's "envelope" or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.

New Insights into Memory Formation and Modification

The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.

Spontaneous Brain Activity Drives Early Neural Circuit Formation

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -; four legs, fur, a tail, etc. -; a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen?

New Approach for Targeted Genome Editing in Wild Populations

Researchers from Macquarie University and the California Institute of Technology have discovered a novel method that, when published in Nature Communications on August 13th, 2024, might make it easier and more controllable for scientists to modify the genetic composition of wild populations than when using gene drives.
