New clinical trials for treatments of fatal prion diseases and the impact of organic farms on pesticide use. Prions are misfolded proteins causing brain damage. Organic farms reduce pesticide use, but conventional farms use more when near organic ones.
New treatments for prion diseases show promise in clinical trials by blocking protein production in the brain.
Organic farms reduce pesticide use in neighboring conventional farms, impacting agricultural sustainability and pest management.
Deep dives
Progress in Prion Disease Treatments
New tactics in the treatment of prion diseases are offering hope to patients and researchers. Prions, misfolded proteins causing fatal neurodegenerative diseases, have been a longstanding challenge since their discovery in the 1980s. Recent advancements include clinical trials for an anti-sense oligonucleotide that blocks protein production in the brain, potentially halting the progression of the disease.
Spillover Effects of Organic Agriculture
Organic agriculture's influence extends beyond its fields, impacting neighboring non-organic farms. Research suggests that clustered organic farms reduce pesticide use in surrounding conventional farms, contributing to a more sustainable agricultural landscape. Spatial separation between organic and conventional fields minimizes pests and pesticide use, highlighting the ecological and economic implications of organic farming.
Challenges and Innovations in Pest Management
Natural enemies play a crucial role in controlling pests on organic farms, influencing neighboring conventional farms as well. The presence of natural enemies on organic fields reduces the need for synthetic pesticides, leading to a spillover effect that benefits nearby non-organic farms. Understanding these dynamics can inform pest management strategies and sustainable agricultural practices.
Implications for Policy and Land Management
As the organic agriculture industry grows and policy initiatives promote organic farming, insights from spillover effects and reduced pesticide use can guide strategic land management and policy decisions. Encouraging spatial clustering of organic farms and promoting sustainable agricultural practices based on ecological interactions offer pathways towards more environmentally friendly and efficient farming practices.
New clinical trials for treatments of an always fatal brain disease, and what happens with pests when a conventional and organic farm are neighbors
First up on this week’s show, a new treatment to stave off prion disease goes into clinical trials. Prions are misfolded proteins that clump together and chew holes in the brain. The misfolding can be switched on in a number of ways—including infection with a misfolded prion protein from an animal or person. Staff Writer Meredith Wadman talks with host Sarah Crespi about new potential treatments—from antisense nucleotides to small molecules that interfere with protein production—for these fatal neurodegenerative diseases.
Next on the show: Freelance producer Katherine Irving talks with Ashley Larsen, associate professor of agricultural and landscape ecology at the University of California, Santa Barbara, about the effects of organic farms on their neighbors. If there are lots of organic growers together, pesticide use goes down but conventional farms tend to use more pesticides when side by side with organic farms.
