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 ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

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 ...

For the first time, scientists have grown functional, brain-like tissue without using any animal-derived materials or added biological coatings. The development opens the door to more controlled and ...

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 ...

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 ...

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 ...
