Cells shrink a major internal structure as they age. New research shows this downsizing is deliberate—and linked to longer ...

Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal ...

A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be ...

Biomedical engineers are now able to take a live, holistic look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells and ...

Researchers have long faced a blunt limitation in biology. They could delete proteins or switch genes off, but they could not finely tune how much of a protein existed in specific tissues over an ...

Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and Northwestern University report they have succeeded in regenerating fully ...

Glial cells are an integral part of the human nervous system. They help support and nourish nerve cells, or neurons. Several types of glial cells exist. Glial cells are the “glue” of the nervous ...

3D surface of the fruit fly wing disc before (left) and after (right) eversion. Highlighted in blue is the pouch region, which transforms from a radially symmetric dome into a curved fold by ...
