Dr. Cynthia Rosenzweig has been named the 2022 World Food Prize Laureate for her pioneering work in modeling the impact of climate change on worldwide food production. Rosenzweig founded the Agricultural Model Intercomparison and Improvement Project (AgMIP), a globally integrated transdisciplinary network of climate and food system modelers. AgMIP has directly helped lawmakers in more than 90 countries enhance their food systems' resilience to climate change. Rosenzweig will receive the $250,000 prize officially in an October ceremony.
Japanese Researchers Develop Electric Chopsticks To Enhance Salty Taste

Homei Miyashita, a scientist at Japan's Meiji University, has developed a pair of chopsticks that increases the perception of saltiness by 1.5 times. The device transmits sodium ions from food to the mouth using a weak electrical current. Miyashita and the beverage maker, Kirin, hope to refine and commercialize the device as early as next year in Japan, where sodium intake is double that recommended by the World Health Organization.
Scientists Raise Pizza Dough Without Yeast Or Chemical Leaveners

Yeast is what usually puffs up pizza dough. But there is another way, according to materials scientist Ernesto Di Maio. He and his team at the University of Naples Federico II got similar results by infusing dough with gas at high pressure in an autoclave (pressurized oven) then releasing the pressure during baking. Through a gas inlet, they pumped in carbon dioxide, helium, or air, and brought the dough interior to a pressure of 10 atmospheres (about five times higher than in a standard pressure cooker) and a temperature of 302°F for 10 minutes. The end result? “We tried it, and it was nice and crusty and soft,” said Di Maio.

Tastes that we perceive, including sweet, salty, bitter, and umami, can be traced to biological needs. Sweet foods are sources of needed calories and salty foods provide the mineral needed for proper fluid balance and nerve function. But there's no known biological need for sour foods. And yet we love them, at least up to a certain concentration. Scientists have recently dug deeper into the acidic conundrum and come up with some interesting theories on why we love lemonade as much as kimchi and yogurt.
Polyphenols In Rosemary Can Remove Fishy Odors, Study Says

Fishy smells can overpower and persist in a dish, a room, or even a pan. A new study in the Journal of Food Science has found a potential solution: rosemary. Researchers tested the deodorizing effects of rosemary, ginger, garlic, angelica, fennel, nutmeg, cardamom, cinnamon, star anise, and bay leaf. Rosemary was the most effective, reducing fish aromas by 58%. The scientists isolated three phenolic compounds in rosemary responsible for neutralizing fishy aromas: rosmarinic acid, carnosic acid, and carnosol. All three will be in my dinner tonight.
Psychologist Explains Why Food Is The Root Of All Human Disgust

Maggots. Roaches. Pus. What is it that makes them so repulsive? According to food psychologist Paul Rozin, it's part survival instinct. We perceive feces and rotting meat as disgusting so that we don't eat them and get sick or die. But dogs didn't get the memo that shit smells bad. And that's where things get interesting. Disgust is more than a biological reaction. It's a fungible human emotion related to cultural norms of purity, propriety, and even politics. What's disgusting to some is delicious food to others. Does that mean you should eat maggots? Chacun son goût!
