Keeping a cell's nucleolus compact may be key to fighting aging
The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were elucidated in yeast, a model ...

Scientists develop AI tool for personalized phage therapy as a targeted alternative to antibiotics
With the rapid development of antibiotics in the 1930s, phage therapy—using viruses known as bacteriophages or phages to tackle bacterial infections—fell into oblivion. But as the current rise in antibiotic resistance ...

Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated ...

tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein ...
