Study: Ribosomes are Functionally Diverse
Diana Kwon | Jun 22, 2017
New research suggests that the cells’ protein factories have preferences for specific messenger RNAs they translate.
Mouse Livers Grow and Shrink Daily
Abby Olena | May 4, 2017
Feeding-fasting rhythms and light-dark cycles direct regular changes in organ and cell size, as well as ribosome number and protein levels.
Noncoding RNA Helps Cells Recover from DNA Damage
Diana Kwon | May 1, 2017
Scientists discover transcripts from the same gene that can express both proteins and noncoding RNA.
Starvation Response Triggers Melanoma Invasion
Catherine Offord | Apr 1, 2017
Through similar mechanisms, amino acid depletion in culture and cytokine activity in the tumor microenvironment prompt cancer cells to metastasize.
Top Technical Advances 2016
Kerry Grens | Dec 15, 2016
The year’s most impressive achievements include methods to watch translation in cells, trace cell fates, avoid mitochondrial mutations, edit DNA, and build antibiotics from scratch.
Protozoans Found With No Dedicated Stop Codons
Karen Zusi | Oct 1, 2016
Some ciliates use the same trio of nucleotides to code for an amino acid and to stop translation.
How to Track Translation in Living Cells
Ruth Williams | Oct 1, 2016
Four independent research groups develop techniques for visualizing peptide production in living cells.
Ciliates Are Genetic-Code Deviants
Karen Zusi | Sep 30, 2016
Traditional stop codons have a double meaning in the protozoans' mRNA, sometimes calling for an amino acid during translation.
Scientists Catch Translation in the Act
Ruth Williams | Sep 30, 2016
Newly developed techniques from four different groups rely on the same basic steps to track translation in live cells.
