When your brain reacts strongly to the taste of food right away, it seems to dial down the later dopamine surge from your stomach feeling full—like your brain is balancing taste and nutrition.
Descriptive
The more you want to eat something, the more dopamine shows up in certain brain areas that track desire—your brain’s ‘I want more’ signal.
When you eat tasty food, your brain releases dopamine right away from the taste, and then again later from your body sensing the nutrients—two different brain areas handle each part.
Even when methylene blue was given with another drug called lithium, it still didn’t help the ALS mice live longer or move better.
In another type of ALS mouse, methylene blue didn’t help them move better or change any of the abnormal brain proteins or inflammation markers that are linked to the disease.
Giving methylene blue to mice with a form of ALS didn't help them live longer, move better, or stop their nerve cells from dying, even though it was thought to help the brain.
A part of the rat brain called the ventromedial hypothalamus helps control eating when the rat is hungry, and dopamine signals through D1 receptors are part of how it works.
A certain type of brain chemical signal in the hunger center of fasted rats helps tell them to eat more.
The rats ate more because of the brain receptor change—not because they were moving around more or less.
When scientists turned on a specific type of brain receptor in the hunger center of fasted rats, the rats ate more food—and when they turned it off, the rats ate less.
With added olive extract, olive oil can be fried longer without breaking down into low-quality oil—especially at lower temperatures.
Quantitative
Frying olive oil too long breaks down its natural compounds and creates new ones—but adding olive extract slows this breakdown and even boosts total antioxidants for the first few hours.
Even with added extract, frying olive oil too long makes it lose its good taste—but the extract still makes it taste less rancid than plain oil.
When you add olive extract to frying oil, it helps keep more of the natural plant compounds that give olive oil its health benefits—even after long frying.
When you add a special olive extract to olive oil, the healthy antioxidants in it don’t break down as fast—even when you fry it for hours at high heat.
Adding a natural olive extract to olive oil helps it resist going rancid when used for deep frying at high heat for a long time—much longer than plain olive oil.
A tiny amount of methylene blue helps heart cells make energy better, but too much actually hurts them — it’s a classic case of 'less is more'.
Adding methylene blue doesn’t change how well heart cell power plants can hold onto calcium, meaning it doesn’t protect against the pore that can cause cell death under stress.
Heart cells from diabetic rats have weaker power plants that leak more harmful molecules than those from healthy rats, which matches what scientists expect in diabetes-related heart damage.
Methylene blue makes heart cell power plants produce more harmful molecules when using one fuel (glutamate/malate), but less when using another (succinate), showing its effect depends on what the cell is burning.
Adding a tiny amount of methylene blue to heart cell power plants makes them use oxygen more efficiently, no matter what fuel they're burning.
These brain cells only make mice want salt—not water or food—and don’t affect how much they move around.
If you block the salt taste receptors in a mouse’s mouth, it can’t tell it’s tasted salt—so its brain doesn’t stop craving salt, even if it’s had enough.
Mechanistic
The brain uses two different signals to control salt craving: one slow signal that says 'we need salt' and one fast signal that says 'you tasted salt, stop now'—and they work together to make the mouse eat just enough.
