The Obtain: herbicide-resistant weeds, and an octopus-inspired adhesive


That is right this moment’s version of The Obtain, our weekday publication that gives a every day dose of what’s occurring on the earth of know-how.

The weeds are successful

For the reason that Nineteen Eighties, increasingly vegetation have developed to change into resistant to the biochemical mechanisms that herbicides leverage to kill them. This herbicidal resistance threatens to lower yields—out-of-control weeds can cut back them by 50% or extra, and excessive circumstances can wipe out complete fields.

At worst, it could actually even drive farmers out of enterprise. It’s the agricultural equal of antibiotic resistance, and it retains getting worse. Weeds have developed resistance to 168 totally different herbicides and 21 of the 31 identified “modes of motion,” which suggests the precise biochemical goal or pathway a chemical is designed to disrupt.

Agriculture must embrace a range of weed management practices. However that’s a lot simpler mentioned than carried out. Learn the complete story.

Our meals techniques account for a serious chunk of world greenhouse-gas emissions, however some companies are trying to develop options that might assist handle the local weather impacts of agriculture. That features two corporations on the recently-announced 2024 record of MIT Expertise Evaluate’s 15 Local weather Tech Corporations to Watch. Pivot Bio is inventing new fertilizers, and Rumin8 is working to deal with emissions from cattle.  

Be a part of MIT Expertise Evaluate senior editor James Temple and senior reporter Casey Crownhart right this moment at 12pm ET right this moment for a subscriber-exclusive Roundtable diving into the way forward for meals and the local weather with particular friends 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 brand new solution to perceive our world

February 2024

Environmental DNA is a comparatively cheap, widespread, probably automated solution to observe the range and distribution of life.

In contrast to earlier strategies, which might establish DNA from, say, a single organism, the strategy additionally collects the swirling cloud of different genetic materials that surrounds it. It may possibly function a surveillance software, providing researchers a method of detecting the seemingly undetectable.

By sampling eDNA, or mixtures of genetic materials in water, soil, ice cores, cotton swabs, or virtually any surroundings conceivable, even skinny air, it’s now potential to seek for a selected organism or assemble a snapshot of all of the organisms in a given place.

It presents an exciting — and probably chilling — solution to gather details about organisms, together with people, as they go about their on a regular basis enterprise. Learn the complete story.
