Autonomous UV robots provide a promising alternative to the billion pounds of chemical pesticides applied across American farms each year.
American agriculture is embracing advanced technology as TRIC Robotics introduces large scale autonomous robots. These machines use ultraviolet light to destroy crop pests and diseases instead of relying on traditional chemical sprays.
The company was founded by CEO Adam Stager. It addresses the farming sectors heavy dependence on chemical pesticides which total roughly one billion pounds of use in the United States annually.
The robots operate independently through the night. They move across fields to target and eliminate pests and pathogens while leaving no toxic residues behind. The technology first launched on commercial strawberry farms and is now expanding to additional crops.
Although automation can raise worries about job displacement TRIC Robotics emphasizes that the system actually supports workers. It creates productive night shift opportunities that were previously unavailable.
Farmers facing challenges with pesticide resistant pests have responded positively to the innovation. Successful trials on large commercial operations are helping the technology reach smaller farms as well. This move toward cleaner methods may gradually reduce dependence on chemicals such as glyphosate and support a more sustainable approach to food production.
Scientists have discovered that the fungus Aspergillus tubingensis, isolated from a landfill in Islamabad, Pakistan, can rapidly break down polyurethane, one of the world’s most durable plastics. This material is widely used in insulation, furniture, footwear, coatings, and synthetic leather, and it typically persists in the environment for hundreds of years.
In laboratory tests, the fungus colonizes the surface of polyurethane films, secreting enzymes that disrupt its chemical bonds. Scanning electron microscopy revealed clear signs of degradation, including cracks, pits, and surface erosion. Within just two months in liquid culture, the plastic films were broken down into smaller fragments, with near-complete degradation observed.
This represents the first reported case of A. tubingensis degrading polyurethane. The process is an example of mycoremediation, the use of fungi to clean up environmental pollutants. Other fungi have also shown the ability to use plastics as a primary food source, even in low-oxygen landfill conditions.
Researchers are now exploring the potential of fungal enzymes for large-scale applications, such as bioreactors, to help address the global plastic waste crisis. If scaled effectively, these biological approaches could offer a practical, low-cost method to reduce the billions of tons of persistent plastic accumulating worldwide.

If I bought a new #Corvette it would absolutely be the #GrandSport but I'm still disappointed in no manual option. As impressive as the new cars are, I feel like I'm riding along and not driving them...
Chevy's New Small-Block V8 Proves Size Does Matter https://t.co/FUoBVxoLIG
#MilwaukeeTool needs to sell Packout foam inserts independent from the sets. I purchased old Packout socket organizers and want a setup like the new mechanic set but I'm not buying the set again for the foam. Now I have the 30 pc pivot head ratchet wrench set and want drawer foam
Those were the better days of my life as far as connecting with people. When you hung out with people, they were there both mentally and physically rather than lost in their electronic devices
I had the pleasure of renting a 2026 @chevrolet#Corvette#Stingray. I absolutely loved the car and the DCT but couldn't help but feel slightly bored driving it. The car is missing its soul without a manual. Disappointed they didn't put the #Tremec manual in the #C8#GrandSport
