New insights into a fundamental process in mitochondria

Researchers at Karolinska Institutet have uncovered the function of the release factor mtRF1 in the final steps of mitochondrial protein synthesis. The study, published in Nature Communications, reveals new insights into ...

Key regulator of cell growth deciphered

The mTOR protein plays a central role in cell growth, proliferation and survival. Its activity varies according to the availability of nutrients and some growth factors, including hormones. This protein is implicated in several ...

Small proteins play big role in cellular energy balance

Scientists at Duke-NUS Medical School have discovered new molecular details of how cells ensure that their energy supply is adjusted to meet energy demand. Their study, carried out in collaboration with researchers at the ...

Self-assembling molecules could help in cancer therapy

Treatment of cancer is a long-term process because remnants of living cancer cells often evolve into aggressive forms and become untreatable. Hence, treatment plans often involve multiple drug combinations and/or radiation ...

Light-powered microbes are super-producing chemical factories

Sharing is key to living in society, whether it's toddlers sharing toys or nations sharing natural resources; but there's no avoiding the fact that one side getting more means that the other side gets less. Now, researchers ...

New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...
