A fresh, approachable read on questions from across science. Explore everyday observations, surprising connections, and the explanations worth slowing down for.
A slower read. A wider world of science. ↓Yes. A urinary tract infection can cause fatigue and tiredness, and the sleepiness is usually an immune signal rather than a direct effect of bacteria in the bladder.

Centripetal force is the real, inward force that makes an object travel in a circle; centrifugal force is a fictitious outward force that appears only in a rotating observer's frame.
A little more about this →Yes, a UTI can cause period-like cramps. The pain is real and pelvic, but it comes from infected, inflamed bladder and urethral tissue triggering the same muscle contractions and nerve pathways your uterus uses during menstruation — not…
A little more about this →The carnivore diet's main benefits are short-term and largely indirect: it eliminates processed foods and most allergens, produces rapid water-weight loss, and simplifies eating enough to cut calorie intake.
A little more about this →Ceftazidime and cefepime are both third- and fourth-generation cephalosporins with antipseudomonal activity, but cefepime is the more balanced option: it resists common beta-lactamase hydrolysis better and retains more gram-positive…
A little more about this →Cultivating Bacillus subtilis for industrial fermentation means growing a Gram-positive, endospore-forming bacterium under controlled conditions of carbon source, nitrogen, oxygen, pH, and temperature so that biomass, enzymes, or specialty…
A little more about this →Yes, a stye can cause a headache, but usually only a mild, one-sided one that tracks with the swelling.
A little more about this →Yes—a man with Down syndrome can father a child, but it is uncommon. Most men with trisomy 21 have impaired fertility, and documented paternities are rare.
A little more about this →Coughing up phlegm is the airway's clearance reflex: mucus traps inhaled particles and pathogens, and a forceful expiratory burst moves the loaded secretion up and out.
A little more about this →A detox shampoo for dandruff works only when it delivers an antifungal or exfoliating agent to the scalp long enough to disrupt the yeast that drives flaking.
A little more about this →Yes, a Pap smear can cause light spotting or minor bleeding in some people, because the procedure deliberately scrapes cells from the cervix, a surface rich in tiny blood vessels.
A little more about this →Cephalosporins are beta-lactams because their core is a four-member beta-lactam ring fused to a six-member dihydrothiazine ring, forming a bicyclic nucleus called 7-aminocephalosporanic acid (7-ACA).
A little more about this →No. Most people with alcohol use disorder never develop cirrhosis, and a substantial share never develop any clinically significant alcohol-related liver disease.
A little more about this →Yes, a diesel engine can run on natural gas, but not as a drop-in fuel. Natural gas has a very low cetane number, so it will not self-ignite under diesel-like compression.
A little more about this →Most people who take allergy pills do not gain weight from them, because the common second-generation antihistamines—loratadine, cetirizine, fexofenadine—are not strongly linked to fat accumulation.
A little more about this →Yes, a urinary tract infection can cause gas and digestive problems, though the connection is indirect. A UTI does not typically infect the gut.
A little more about this →Ceftriaxone is not reliably active against Enterococcus species, and it is never a first-line choice for enterococcal infection.
A little more about this →Yes, a rotator cuff tear can partly heal on its own, but the repair is usually incomplete scar tissue rather than restored tendon.
A little more about this →Close contact with a COVID-exposed person does not automatically mean infection; transmission depends on the exposed person's infectiousness, the shared air, the duration, and your own immune status.
A little more about this →Common signs of dehydration include thirst, dark yellow urine, dry mouth, fatigue, dizziness on standing, and reduced urine output; in adults, warning signs that warrant urgent care are confusion, fainting, rapid heartbeat, sunken eyes,…
A little more about this →An X-ray cannot show a meniscus tear directly. The menisci are fibrocartilage, and cartilage is radiolucent on plain radiography, meaning it does not attenuate X-rays enough to appear as a distinct structure.
A little more about this →ACE inhibitors cause hyperkalemia, not hypokalemia. By blocking angiotensin-converting enzyme, these drugs lower aldosterone, and lower aldosterone reduces potassium excretion in the kidney’s collecting duct.
A little more about this →Yes. MRI can detect bladder cancer and, in expert hands, determine how deeply the tumor invades the bladder wall and whether it has spread to nearby nodes or organs.
A little more about this →Yes, a mole can itch, though the sensation is usually harmless and temporary. Melanocytic nevi contain functional nerve endings, mast cells, and blood vessels, so they can itch from dry skin, friction, histamine release, or inflammation.
