Medieval fable attributed to Aesop Gustave Doré's illustration of La Fontaine's fable, c. 1868 Belling the Cat is a fable also known under the titles The Bell and the Cat and The Mice in Council. In the story, a group of mice agree to attach a bell to a cat's neck to warn of its approach in the future, but they fail to find a volunteer to perform the job. The term has become an idiom describing a group of persons, each agreeing to perform an impossibly difficult task under the misapprehension

Image by Getty / Futurism Neuroscience/Brain Science Should you be worried that your brain probably contains enough plastic to fashion a disposable spoon? Yes, new research suggests: you should. In a new study published in the journal Environmental Research Communications, researchers found that mice which were regularly exposed to microplastics in their diet developed symptoms of Alzheimer's disease, the most common form of dementia, in less than a single month.

Scientists just found a protein that reverses brain aging

news.ycombinator.com Unknown 2025-10-31 03:56:27

Aging is particularly harsh on the hippocampus -- the brain region responsible for learning and memory. Now, researchers at UC San Francisco have identified a protein that's at the center of this decline. They looked at how the genes and proteins in the hippocampus changed over time in mice and found just one that differed between old and young animals. It's called FTL1. Old mice had more FTL1, as well as fewer connections between brain cells in the hippocampus and diminished cognitive abilit

Our Brains Contain Lithium—and Its Loss Might Help Drive Alzheimer’s, Study Finds

Alzheimer’s disease is one of the cruelest conditions a person can develop. And even with recent advances, there’s only so much that can be done once its symptoms emerge. Research out this week might highlight a critical and previously missed factor driving the disease, one that could even lead to new treatments. Scientists at Harvard Medical School led the study, published Wednesday in Nature. By studying human brain samples and mice, they found evidence that our brains naturally contain the e

SteelSeries Rival 3 Gen 2 Review: Good Budget Gaming Mice

Over the years, computer mice have become expensive. Everything has become expensive. It can be frustrating to look at a list of gaming mice and see even the cheapest options approaching $80, especially when games now cost $80 and new graphics cards regularly pass the $1,000 mark. This is where budget-oriented mice are perfect.

You'd be forgiven for thinking that every computer mouse is just like every other computer mouse. It clicks things on your screen and lets you move your cursor around. Believe it or not, there are quite a few ways companies can differentiate their mice from each other, especially when it comes to gaming.

Scientists Find Evidence of Grim Long-Term Effects of Fad Diets

Image by Getty Images Studies The way Westerners diet — often alternating dubious and restrictive food regimens with binge eating, in a phenomenon known as "yo-yo dieting" — may be messing with their gut flora and their brains. In a new study published in the journal Advanced Science, researchers from France's University of Rennes and Paris-Saclay University found, after conducting a series of studies with mice, that yo-yo diets appeared to result in long-lasting changes to their gut bacteria.

Scientists Gene Hack Mice So Their Livers Produce Their Own Ozempic-Like Drug

The popularity of Ozempic and Wegovy as diabetes and weight loss medications has skyrocketed. But how far would people go to avoid one of their major drawbacks—the need for weekly injections? A study out today shows it’s possible to genetically modify mice to make their own Ozempic-like drugs.

Changing one gene can restore some tissue regeneration to mice

Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered. Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, through eyes and parts of brain, to the spinal cord. Mammals, though, have mostly lost this ability somewhere along their evolutionary path. Regeneration persisted, in a limited number of tissues, in just a few mammalian species like rabbits or goats. “We were trying to learn how certain anima
