BEGIN EXPLORING ↓SCIENCE & IDEAS / A WIDER PERSPECTIVEYes, many people with dissociative identity disorder hear voices, but the experience differs from psychotic hallucinations in origin, texture, and control.

01 / IDEAS WORTH EXPLORING ↗Yes, burping is a reasonable practice for most newborns, but it is not a medical requirement, and no major pediatric body mandates it.
Yes, a virus can cause hives. Viral infection is one of the most common triggers of acute urticaria in children and a recognized cause in adults. The wheals are not caused by the virus attacking skin directly.
No, viruses do not respire. They have no lungs, gills, mitochondria, or respiratory chain, and they cannot extract energy from nutrients.
Piranhas can and do bite humans, but fatal attacks are vanishingly rare and almost never involve the "feeding frenzy" of popular myth.
Cats move their tails both on purpose and by reflex, and the two systems are not alternatives. Voluntary movement originates in the motor cortex and is executed through roughly 20 paired tail muscles and the cauda equina nerves.
Yes, most heating pad burns go away, but the timeline runs from about three days to several weeks depending on depth, and some leave permanent scars.
No. Dreaming occurs in every sleep stage, but the dreams differ in character, recall, and vividness.
Most cats tolerate and often seek skin-to-skin contact with familiar humans, but the preference is conditional rather than universal.
Yes, a potassium imbalance can cause tinnitus, but the link is indirect and dose-dependent. Potassium sets the resting voltage of every auditory nerve cell.
Yes, urologists perform vasectomies, and they are the specialists most commonly trained to do so. A vasectomy is a minor surgical procedure that cuts or seals the vas deferens, the tube that carries sperm from each testicle.
Do cold showers help colds? No strong evidence shows they shorten or cure a cold.
Yes. Alcohol affects men and women differently at every stage: how it is absorbed, how it is distributed through the body, how fast the liver clears it, and how much tissue damage a given dose causes.
Do squirrels carry rabies? Yes, squirrels can carry rabies, but the CDC has never confirmed a case of rabies transmission from a squirrel to a human.
No, yellow jackets do not die after stinging. Unlike honey bee workers, whose barbed stinger anchors in elastic skin and tears free with the venom sac and part of the abdomen, a yellow jacket's stinger is smooth and retracts cleanly.
Yes. Panic attacks typically rise, peak, and fall rather than holding at full intensity, and most reach peak intensity within about 10 minutes of onset, according to the DSM-5-TR, the diagnostic manual published by the American Psychiatric…
No. Alkaline water does not hydrate better than regular water in any way that matters for everyday health. Both are water, and your body absorbs water the same way regardless of its pH.
No, rabbits do not have horns. They have no horn tissue, no bony horn cores, and no horns hidden under fur or skin. What people sometimes see as “horns” are ears, fur patterns, or a treatable skin growth called trichoblastoma.
Yes, psychopaths laugh, but their laughter is often qualitatively different from typical laughter.
Does alcohol affect a steroid injection? Yes, it can, mainly by adding to the immunosuppressive and blood-sugar-raising effects of the corticosteroid rather than by any direct chemical interaction.
Yes, people have green eyes, but the trait is uncommon: roughly 2 percent of the world’s population carries it, and about 9 percent of Americans do.
No, models do not have acne. Live models are humans who can develop acne like anyone else, but the term "model" also covers mannequins, 3D avatars, and AI-generated figures, which have no skin, no sebaceous glands, and no biology capable…
Yes, a lion’s mane jellyfish can kill you, but death is rare and almost always indirect.
Saunas can raise growth hormone (GH) acutely, but the effect is modest, short-lived, and highly variable.
