The implementation of distinct gene expression profiles is essential for animal development and physiology. Post-transcriptional silencing by small regulatory RNAs such as miRNAs plays essential roles ...

Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of cells ...

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 ...

Investigators have created computer-generated models to bridge the gap between 'test tube' data about neurons and the function of those cells in the living brain. Their study could help in the ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

Cyclin-dependent kinases (CDKs) form a conserved superfamily of eukaryotic serine-threonine protein kinases whose activity requires the binding of a cyclin protein. CDKs are involved in many aspects ...

BEAUFORT, N.C. – Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student’s study of ocean microplastics. The presence of polymer ...

A storage center on the Moon could serve as a backup resource for the biological record and for genetic resurrection attempts. Share on Facebook (opens in a new window) Share on X (opens in a new ...
