- 1Scientists Reverse-Engineer Insect Smell Receptors to Find Moth Pheromones●Scientists Reverse-Engineer Insect Smell Receptors to Identify Moth Sex Pheromones
Researchers have reverse-engineered insect smell receptors to identify the sex pheromones of moths, according to a report by Bioengineer.org. By decoding how these olfactory receptors detect chemical signals, scientists can pinpoint the exact compounds moths use to attract mates. The work could lead to new pest-control methods that disrupt moth mating without pesticides, and highlights how receptor engineering is advancing the study of chemical communication in insects.
- 2Whistleblower says Driscoll's berries sent to Canada over chemical limits●Whistleblower alleges millions of Driscoll’s berries sent to Canada with excess chemical levels
A whistleblower alleges that millions of Driscoll's berries were shipped to Canada despite containing pesticide levels above permitted limits, according to CBC reporting. The claim raises questions about food safety inspections and how much contaminated produce may have reached Canadian consumers before being flagged.
- 3485 chemicals in US pesticides linked to breast cancer●Research finds 485 chemicals in US pesticide products linked to breast cancer
New research has identified 485 chemicals used in pesticide products in the United States that are linked to breast cancer. The findings raise questions about regulatory oversight of agricultural chemicals and women's exposure to carcinogens through food and the environment. Commenters are debating the scale of the risk and how regulators should respond.
