As flowers bloom and fruits ripen, they emit a colorless, sweet-smelling gas called ethylene. MIT chemists have now created a tiny sensor that can detect this gas in concentrations as low as 15 parts per billion, which they believe could be useful in preventing food spoilage.
The sensors, which are made from semiconducting cylinders called carbon nanotubes, could be used to monitor fruit and vegetables as they are shipped and stored, helping to reduce food waste, says Timothy Swager, the John D. MacArthur Professor of Chemistry at MIT.
“There is a persistent need for better food management and reduction of…
Though Asian American Pacific Islander (AAPI) Heritage Month draws to an end today, everyday is as good a time as anyone to learn how to cook Asian cuisine — and the right kitchen tools are a good start. We spoke to experts about cookware they recommended and found highly rated options to consider.

While shopping, keep in mind that Asia is the world’s largest and most populous continent. Because various countries, regions and families have unique styles of cooking and eating, no one tool can cover it all. Thus, the list…
Steps were taken in Canada to reduce the use of Bisphenol A (BPA), a toxic chemical linked to prostate and breast cancer, commonly found in plastics, the lining of food cans, water bottles, and paper receipts. But in many cases, it has been replaced with similar hormone disrupting chemicals, such as Bisphenol S (BPS). A new study from McGill University shows that every day Canadians are exposed to BPS in the fresh foods they eat, as chemicals migrate from labels on the packaging materials into the food.
“BPA is a chemical that can interfere with hormones in the human body…
Over the past two months, the price of the raw material used to produce rapeseed oil has decreased by nearly €200 per ton, or up to one third. Rapeseed oil prices on store shelves, however, won’t be suitable.According to Talis Raak, head of purchasing at Rimi, the retail price of cooking oil increased 20-30 percent at the beginning of the first quarter. Prices stopped rising in April.
“In the case of both sunflower and rapeseed oil, the primary factor in the price decrease was mainly a restored supply chain, and at the moment, product availability was rather good,” Raak…
