- 1Gardener pulls tomato plants, seeks help diagnosing stunted growthβI pulled all the tomato plants today. Some had obvious nematode damage, but those were the bigger healthier plants. Most
A gardener removed all their tomato plants for the season and found nematode damage on the larger, healthier specimens. Most plants showed stunted early growth that picked up once summer heat arrived, and they are asking others for a firm diagnosis of what caused it. Fellow gardeners are weighing in on possible soil pests, nutrient issues or weather effects.
- 2Costa Rica's Marine Nematodes Remain Largely Unknown, Review FindsβΌCosta Ricaβs Marine Nematodes Remain Largely Unknown, Review Finds
A new scientific review concludes that Costa Rica's marine nematodes β microscopic worms living in ocean sediments β remain poorly documented, with most species likely undescribed. The paper highlights how little is known about these organisms despite their role in marine ecosystems, and points to a need for more sampling and taxonomic research along the country's coasts.
- 3Fluorescent Toolkit Reveals Hidden Structure of Worm CuticleβFluorescent Tagging Toolkit Illuminates the Hidden Architecture of the Worm Cuticle
Researchers have developed a fluorescent tagging toolkit that reveals the previously hidden architecture of the worm cuticle, the tough outer layer of nematodes such as C. elegans. By lighting up cuticle structures under the microscope, the method gives scientists a clearer view of how this protective barrier is built and maintained. The advance could support studies of development, molting and animal biology more broadly.
- 4Root-Knot Nematode Study Reveals Cold-Survival TacticsβHow a Devastating Root-Knot Nematode Rewires Its Lipids and Proteins to Survive the Freeze
New research coverage describes how the root-knot nematode, a devastating agricultural pest, restructures its lipids and proteins to survive freezing conditions. The findings explain how the microscopic worm endures cold stress, knowledge that could inform strategies to protect crops from this widespread parasite.
