As a result of intense selection pressures in the 1980s, weeds have adapted to evolve resistance to the biochemical mechanisms that herbicides use to control them. The widespread prevalence of herbicidal resistance poses a significant threat to crop yields, with out-of-control weeds capable of slashing yields by as much as 50% or more, potentially devastating entire fields in extreme cases.
At the very least, it risks pushing farmers to the brink of bankruptcy, potentially driving them out of business altogether. The scourge of modern agriculture, this phenomenon is akin to antibiotic resistance in its impact on our food systems – and unfortunately, it’s continuing to worsen with each passing day. The proliferation of weeds has been marked by an astonishing resistance to 168 distinct herbicides, as well as 21 of the 31 recognized “modes of action,” a term referring to the specific biochemical target or pathway that a given chemical aims to disrupt.
Agricultural practices must adopt diverse and effective methods for weed control to ensure optimal yields. Though simplicity sounds appealing, in practice it’s much more complex. .
Local weather experts never stand still. Across various sectors, from vitality and transportation to agriculture and coverage, there’s always another area to grasp.
As Casey Crownhart, our seasoned local weather reporter, continues to monitor the rapid advancements in local weather technology, she’s eager to explore what the future holds. .
Innovative adhesives technology draws inspiration from the remarkable suction power of an octopus’s tentacle.
Scientists have successfully replicated the remarkable grasp and manipulation abilities of an octopus, developing an innovative tool capable of handling a wide range of objects. The technology may significantly improve underwater development strategies and facilitate the discovery of innovative software for use in regular devices, such as an assistive glove. .
While food production is responsible for a substantial portion of global greenhouse gas emissions, innovative companies are working to reduce the climate footprint of agriculture through sustainable meal options. The report from MIT Technology Review’s 2024 list highlights two companies that have made significant advancements. Two innovative companies, Pivot Bio and Rumin8, are revolutionizing the agriculture industry by developing cutting-edge solutions: Pivot Bio creates novel fertilizers, while Rumin8 tackles the environmental impact of cattle farming by reducing emissions.
Join MIT Know-how Evaluation senior editor James Temple and reporter Casey Crownhart at 12pm ET today for an in-depth exploration of the intersection of food and climate with special guests Karsten Temme, chief innovation officer and co-founder of Pivot Bio, and Matt Callahan, co-founder and counsel of Rumin8.

Brian McNoldy, a senior analysis scientist at the University of Miami’s Department of Atmospheric Science, provides a candid assessment of the 2024 hurricane season.
Environmental DNA, a remarkably cost-effective and far-reaching method, allows for the automated detection of life’s scope and distribution.
Unlike previous approaches that focused on isolating DNA from a single organism, this method also captures the diverse genetic material that surrounds it in a swirling cloud. This innovative technology could potentially serve as a surveillance tool, empowering researchers to identify and track even the most elusive phenomena.
Through the analysis of environmental DNA (eDNA), scientists can now sample mixtures of genetic material from various sources, including water, soil, ice cores, cotton swabs, and even atmospheric samples, allowing for the identification of specific organisms or the creation of a comprehensive inventory of all organisms present in a given location.
Capturing the intricacies of life, including human behavior, through an innovative and unsettling approach yields a thrilling experience that probes the minutiae of existence. .
