Methods like this can help scientists sort through potential drug candidates faster and with more biological detail.

Scientists have often thought of cells as small, bustling cities with parts that resemble factories, power grids and shipping ...

Mitochondria—tiny structures that convert nutrients into energy—are often depicted as discrete kidney bean-shaped objects. But in reality, they form a dynamic, interconnected network throughout the ...

In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete. In eukaryotic cells, however ...

Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling pathways, genes or proteins to change the function of different cells in ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures ...

Volvox parent spheroid: Numerous individual cells can be seen across the entire surface as magenta-colored dots. Developing daughter spheroids appear as a few larger clusters with very small dots. The ...

Meibomian gland carcinoma is one of the rarest and most treacherous malignancies in ocular oncology, and for decades it has ...
