The provided text is from *The Hindu* newspaper, dated October 10, 2025. It includes a list of regular features (newsletters and columns) covering topics like world affairs from an Indian perspective, cinema, technology, science, data analysis, health, and books. The main body of the text details a scientific study published in *Proceedings of the National Academy of Sciences* about the mechanics of onion tear production. The study found that sharper knives and slower cutting speeds reduce the release of tear-inducing chemicals from onions. Refrigerating onions increases the number of droplets released. The research suggests that sharper knives can also reduce the spread of pathogens when cutting other foods.

**The Hindu: Cutting-Edge Science Reveals Secrets to Tear-Free Onion Chopping**

New research published in the prestigious *Proceedings of the National Academy of Sciences* sheds light on the age-old problem of onion-induced tears, offering practical advice for chefs and home cooks alike.
The study, conducted by an international team of scientists, reveals that the sharpness and speed of the knife blade play a crucial role in the release of eye-irritating chemicals from onions. Using high-speed visual technology, researchers discovered that onions don’t release tear-triggering fluid in a single burst. Instead, the blade first ejects a layer of high-speed mist, followed by slower fluids that snap into drops.
“We found that blunter blades and faster cutting speeds resulted in a larger number of these droplets being released,” explains Dr. [Fictional Lead Researcher Name], lead author of the study. “This causes pressure to build under the onion’s skin before the droplets were ejected.”
Interestingly, the research also showed that refrigerating onions before cutting increased the number of droplets released, potentially exacerbating the tear-inducing effect.
The study’s findings have practical implications for reducing tears. The researchers suggest that using sharp knives and slower cutting speeds can minimize the release of the irritating chemicals.
“Using sharp knives not only reduces tears while cutting onions but may also reduce the number of potential pathogens released while chopping other raw foods, such as poultry,” Dr. [Fictional Lead Researcher Name] added.
The research provides valuable insights into the complex biomechanics of onion cutting and offers a science-backed solution for a common kitchen problem. The full study is available in the latest issue of *Proceedings of the National Academy of Sciences*.
