BEGIN EXPLORING ↓SCIENCE & IDEAS / A WIDER PERSPECTIVEYes, an ovarian cyst can cause infection, but this is uncommon: most ovarian cysts are sterile fluid collections, and infection usually requires a second event such as cyst rupture, pelvic inflammatory disease, or pelvic surgery.

01 / IDEAS WORTH EXPLORING ↗Can obesity be cured? Not permanently in most people, but it can be driven into durable remission, and that distinction changes treatment. Obesity is a chronic, relapsing disorder in which the body actively defends its fat mass.
Yes, opossums can carry rabies, but laboratory-confirmed infection is extremely rare. The virus is not a normal part of opossum biology, and the animals are not immune.
Yes, nicotine can kill you, but only at doses far above anything a cigarette, patch, or typical vape delivers.
Yes, neutral runners can wear stability shoes safely if the shoes fit well, feel comfortable immediately, and are introduced gradually. Safety here means no new pain, no blistering, and no change in stride that persists after the run.
Nasal drainage does not cause diarrhea. The mucus you swallow is 95% to 99% water plus mucin proteins, and stomach acid breaks it down within minutes rather than acting as a laxative.
Yes, newborns can have hemorrhoids, but true symptomatic hemorrhoids are uncommon in neonates and young infants. When parents ask, “Can newborns have hemorrhoids?” the short answer is that the anatomy exists but clinical disease is rare.
Yes, neuroendocrine cancer can spread to the brain, but the risk is not uniform. In well-differentiated neuroendocrine tumors, brain metastases appear in roughly 1% to 5% of advanced cases.
Yes — not eating enough can cause acne, though not through the mechanism most people assume.
Yes, neck and shoulder pain can cause chest pain, but the pathway is referred musculoskeletal or neural pain, not a heart attack.
Yes, nicotine can make your heart race. It does so by binding nicotinic acetylcholine receptors in autonomic ganglia, the adrenal medulla, and the carotid body, which increases sympathetic outflow and catecholamine release.
No, your dog should not swim with an active ear infection. Water in the ear canal raises humidity above 80 percent, softens the skin lining, and feeds the bacteria or yeast already multiplying there.
Can nasal spray cause eye floaters? No — no nasal spray ingredient is known to create vitreous opacities directly, and no regulator lists floaters as an established adverse effect of any decongestant, steroid, or saline spray.
Yes, muscle tension can cause vertigo, but almost never by "pinching a nerve."
No, NAD supplements are not an established treatment for multiple sclerosis, and no clinical trial has shown they slow disability or prevent relapses.
Most likely not from the same virus, but yes, a child can get hand foot mouth disease twice. The illness is caused by a group of viruses, not one.
Yes, CPAP can make you gassy, and the cause is usually swallowed air rather than anything the machine manufactures.
Yes, mono can cause pink eye, though it is uncommon rather than typical. Infectious mononucleosis, usually triggered by Epstein-Barr virus (EBV), causes conjunctivitis in roughly 1% to 5% of diagnosed cases.
Mucus itself does not make you sick: it is a protective hydrogel your body produces continuously, and it is the pathogens trapped inside it, not the mucus, that cause illness.
Mold toxicity can contribute to weight gain, but not through a single direct mechanism.
Yes, monkeys can eat some human food, but only a narrow slice of it, and never in human-sized portions. Their digestive system is built for wild fruit, leaves, insects, and bark, not for bread, chips, or sweets.
Yes, a muscle strain can raise your heart rate, and it usually does so through two separate pathways working at once.
Yes, mono can flare up again, but true reinfection is rare. The Epstein-Barr virus (EBV) that causes most infectious mononucleosis never leaves your body; it hides inside memory B cells for life, and in roughly 20 to 30 percent of healthy…
Yes, mold exposure can make you dizzy, but the mechanism is usually indirect rather than a direct toxin attack on the balance organs.
