Wind turbine syndrome. People living below wind turbines suffer from headaches, dizziness, nausea, and loss of sexual function... but only if they've been told that people living below wind turbines suffer from headaches, dizziness, nausea, and loss of sexual function.
Scientists taught rats to drive rat-sized vehicles in exchange for treats. When then offered treats without needing to drive, three quarters of the rats preferred to operate the vehicle to get the treats.
Many of the trained rats were observed taking an unusual pose while watching the scientists set up their vehicles. The scientists had only seen the same pose before in rats that were high on opiates.
I think the most obvious conclusion to draw is that rats enjoy learning and using new skills when there's a reward involved, and that often the skill itself is the reward.
I used to have a tuna casserole recipe that came out of the oven completely grey. Grey fish, grey peas, grey cheese. Very tasty. Quite oily though, so probably best if I don't rediscover the recipe.
In the freezer: minced beef, chicken breast, prawn cutlets, sliced bread, frozen mixed vegetables and packs of diced onion/celery/carrot for soup. Also mozzarella because I buy it by the kilo and like to make Italians cry.
In the cupboard: canned kidney beans, black beans, butter beans, chickpeas, chopped tomatoes, corn kernels, coconut milk. Tuna. Rice, dried fettucine, macaroni and spirals. Red lentils because you can always find them at the supermarket. Jarred pasta sauce.
In the vegetable drawer: onions, carrots, potatoes and (when available) beets, brussels sprouts, cauliflower, broccoli, radishes. Spinach or lettuce.
In the fridge: milk, margarine, at least three kinds of cheese, sliced ham. Jarred crushed garlic, because I'm some kind of human animal.
In the spice rack: cumin, oregano, thyme, bay leaf, parsley, basil, smoked and sweet paprika.
It's yellow.
