A 'door' into the mitochondrial membrane

Mitochondria—the organelles responsible for energy production in human cells—were once free-living organisms that found their way into early eukaryotic cells over a billion years ago. Since then, they have merged seamlessly ...

Researchers discover a rare new blood group system

Scientists from the University of Bristol and NHS Blood & Transplant (NHSBT) have discovered a rare new blood group system. The findings, published in Blood, also solve a 30-year mystery.

Using nanopores to detect epigenetic changes faster

Changes known as epigenetic modifications play an important role in cancer development. Being able to analyze them quickly and reliably could contribute significantly to the further development of personalized therapy. A ...

Asexual reproduction leads to harmful genetic mutations

A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those utilizing sexual reproduction.

Video: 'Mapping' the body with single-cell RNA sequencing

While nearly every cell in the body contains identical genetic instructions packaged in DNA, there is flexibility on how that genetic information is expressed and in turn translated through RNA to create proteins, the building ...

Physicists use AI to find the most complex protein knots so far

The question of how the chemical composition of a protein—the amino acid sequence—determines its 3D structure has been one of the biggest challenges in biophysics for more than half a century. This knowledge about the ...
