Insect sex pheromones, volatile molecules used to attract mates, are used commercially to disrupt breeding behavior of insect pests and can be a good alternative to harmful pesticides. These pheromones have been produced in plants at a low amount and shown to be released as volatiles, but their production…

The vertebrate adaptive immune system is truly an evolutionary marvel. With its ability to mix-and-match segments of immunoglobulin genes, a nearly unlimited diversity of antigens can be recognized. Plants lack this ability, greatly limiting the number of antigens (and pathogens) any individual can recognize.…

Synthetic genetic circuits offer a promising method to achieve beneficial changes in plant phenotypic traits. By combining different activator or repressor transcription factors (TFs) , the expression of target genes may be fine-tuned according to Boolean operations. Here, Brophy et al. describe a method…

Synthetic biology aims to engineer and redesign components of natural organisms for useful purposes.  One of the most prolific areas of synthetic biology is based on the engineering of photoreactive proteins with signaling potential, such as photoreceptors. Natural photoreceptors consist of a prosthetic…

Covid has turned our focus to human viral pathogens, but the challenges we face from cellular pathogens has not gone away, and is increasingly exacerbated by the development of resistance to antibiotics and other antimicrobials. This fine review by Tiwari et al. provides an overview of how antimicrobials…

I guess if this were a normal year, we’d be spending time looking back over the past decade, but Covid-19 has made anything pre-2019 seem like a different lifetime. Still, here’s a retrospective you don’t want to miss. Meng and Ellis take us on a short walk down memory lane through the “second…
