'e-Drive': New gene drive reverses insecticide resistance in pests... then disappears
Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ...

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 ...

AI and genus-conditioned algorithms create precise simulation-ready models of 600,000 existing urban trees
The Irish philosopher George Berkely, best known for his theory of immaterialism, once famously mused, "If a tree falls in a forest and no one is around to hear it, does it make a sound?" What about AI-generated trees? They ...

New structure gives insight into mRNA export and cancers, and how viruses hijack the process to infect their host
The central dogma of biology defines the flow of genetic information: It describes how proteins are made from mRNA templates, which are in turn made from DNA. Exporting the mRNA from inside the nucleus to the site of protein ...
