The Download: herbicide-resistant weeds, and an octopus-inspired adhesive
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
The weeds are winning
Since the 1980s, more and more plants have evolved to become immune to the biochemical mechanisms that herbicides leverage to kill them. This herbicidal resistance threatens to decrease yields—out-of-control weeds can reduce them by 50% or more, and extreme cases can wipe out whole fields.
At worst, it can even drive farmers out of business. It’s the agricultural equivalent of antibiotic resistance, and it keeps getting worse. Weeds have evolved resistance to 168 different herbicides and 21 of the 31 known “modes of action,” which means the specific biochemical target or pathway a chemical is designed to disrupt.
Agriculture needs to embrace a diversity of weed control practices. But that’s much easier said than done. Read the full story.

Everything comes back to climate tech. Here’s what to watch for next.
Climate technology never stands still. From energy and transportation to agriculture and policy, there’s always a new development to get your head around.
Casey Crownhart, our senior climate reporter, has been thinking about where climate tech will go next. Check out her predictions for the future.

This octopus-inspired adhesive can stick to just about anything
What’s new: A new adhesive technology pays homage to one of nature’s strongest sources of suction: an octopus tentacle.
What is it? Researchers replicated an octopus’s strong grip and controlled release to create a tool that manipulates a wide array of objects. It could help improve underwater construction methods or find application in everyday devices like an assistive glove. Read the full story.

Roundtable: Producing climate-friendly food
Our food systems account for a major chunk of global greenhouse-gas emissions, but some businesses are attempting to develop solutions that could help address the climate impacts of agriculture. That includes two companies on the recently-announced 2024 list of MIT Technology Review’s 15 Climate Tech Companies to Watch. Pivot Bio is inventing new fertilizers, and Rumin8 is working to tackle emissions from cattle.
Join MIT Technology Review senior editor James Temple and senior reporter Casey Crownhart today at 12pm ET today for a subscriber-exclusive Roundtable diving into the future of food and the climate with special guests Karsten Temme, chief innovation officer and co-founder of Pivot Bio, and Matt Callahan, co-founder and counsel of Rumin8.

How environmental DNA is giving scientists a new way to understand our world
Environmental DNA is a relatively inexpensive, widespread, potentially automated way to observe the diversity and distribution of life.
Unlike previous techniques, which could identify DNA from, say, a single organism, the method also collects the swirling cloud of other genetic material that surrounds it. It can serve as a surveillance tool, offering researchers a means of detecting the seemingly undetectable.
By sampling eDNA, or mixtures of genetic material in water, soil, ice cores, cotton swabs, or practically any environment imaginable, even thin air, it is now possible to search for a specific organism or assemble a snapshot of all the organisms in a given place.
It offers a thrilling — and potentially chilling — way to collect information about organisms, including humans, as they go about their everyday business. Read the full story.
