Things Worth Noting
Mercury pollution enters waterways from coal plants, volcanoes, gold mining, and other sources. In sediments, bacteria convert it to toxic methylmercury (MeHg), which builds up in fish through bioaccumulation and biomagnification—levels rise dramatically in larger predatory fish like swordfish, tuna, and shark as they eat smaller ones. This poses serious health risks, especially neurotoxicity from […]
Goldfish can indeed learn to “drive” on land, as shown in a fascinating study by researchers at Ben-Gurion University of the Negev. They created a fish-operated vehicle (FOV)—a small robotic tank filled with water on wheels—that moves based on the goldfish’s swimming direction, tracked by a camera and LIDAR. Six goldfish were trained using food […]
Sous vide is a cooking technique that involves vacuum-sealing food in a bag and then cooking it in a temperature-controlled water bath. The food is cooked at a precise temperature, which ensures that it is cooked evenly and retains its flavor and nutrients. This technique is popular among chefs and home cooks because it allows […]
