Nano-nutrients can blunt effects of soil contamination, boost crop yields
One of the pressing problems that the world faces in the era of climate change is how to grow enough healthy food to meet the increasing global population, even as soil contamination rises. Research recently published in Nature Food by an internation.....»»
Scientists discover chemical probes for previously "undruggable" cancer target
Hormone-driven cancers, like those of the breast and prostate, often rely on a tricky-to-target protein called Forkhead box protein 1 (FOXA1). FOXA1 mutations can enable these types of cancers to grow and proliferate. Today, FOXA1 is notoriously diff.....»»
A unified theory for predicting pathogen competition: Exploring how emerging new strains replace previous ones
The COVID-19 pandemic showed that predicting the invasion of a novel pathogen into the human population and its evolutionary potential to generate new variants is crucial for preventing future outbreaks. New research conducted at Princeton University.....»»
Scientists discover "selfish DNA" crucial for early human development
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found......»»
