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. ↓Are edibles bad for you? Not inherently, but they carry risks that inhaled cannabis does not, and most of those risks trace to one fact: edible THC is processed by the liver into a more potent metabolite called 11-hydroxy-THC.

Alcohol proof is exactly twice the alcohol by volume (ABV) percentage in the United States: 80 proof means 40% ABV, 100 proof means 50% ABV, and 151 proof means 75.5% ABV. The U.S.
A little more about this →Always sweating in your sleep usually means your body's heat-dissipation system is misfiring during REM sleep, when your core temperature should drop about 1 degree but instead stays elevated.
A little more about this →Alocasia types fall into two practical groups: the compact jewel alocasias, which stay under 24 inches and tolerate moderate indoor light, and the giant elephant-ear alocasias, which reach 5 to 10 feet and demand high humidity plus bright…
A little more about this →An alcohol prep pad is a small, single-use wipe saturated with isopropyl alcohol, usually 70% concentration, used to clean intact skin before a needle stick, lancet poke, or minor procedure.
A little more about this →Acetylcholinesterase is a hydrolase enzyme (EC 3.1.1.7) that terminates cholinergic neurotransmission by splitting acetylcholine into choline and acetate, and it is best classified as a cholinergic synapse–terminating enzyme rather than an…
A little more about this →Allopatric and sympatric speciation are two routes by which one species splits into two.
A little more about this →All cancer ribbon colors and what they mean come down to a voluntary convention, not an official code. Each color is a shared symbol adopted by patient groups and advocacy organizations to signal awareness for a specific cancer type.
A little more about this →Abnormal white blood cell counts almost always trace to one of four root causes: a normal immune reaction (infection, inflammation, stress, steroids), a marrow production problem (nutritional deficiency, drug suppression, marrow failure),…
A little more about this →African milk tree poison is the milky sap of Euphorbia trigona, and it is a chemical irritant rather than a true toxin in the classic sense: the latex contains diterpene esters that mimic and dramatically amplify skin irritation, causing…
A little more about this →Aldosterone and vasopressin differ in where they act, how they act, and what they regulate.
A little more about this →Alcaligenes faecalis infection is an opportunistic bacterial infection caused by a Gram-negative, non-fermenting rod that is normally harmless in soil and water but can colonize wounds, the urinary tract, the respiratory tract, and the…
A little more about this →Cellular respiration produces a maximum of about 30 to 32 ATP per glucose molecule, distributed across three ATP-generating stages: glycolysis nets 2 ATP, the citric acid cycle (via GTP) yields 2 ATP, and oxidative phosphorylation…
A little more about this →Albumin after paracentesis is given to prevent post-paracentesis circulatory dysfunction, the drop in effective blood volume that follows large-volume fluid removal.
A little more about this →Acrylic fiber is a synthetic polymer made from at least 85% acrylonitrile, and its main uses are apparel and home textiles (sweaters, fleece, blankets, upholstery), outdoor fabrics (awnings, boat covers, tents), industrial filtration and…
A little more about this →Adenosine triphosphate (ATP) is a small nucleotide that powers nearly every energy-requiring process in living cells by transferring its terminal phosphate group to other molecules.
A little more about this →Affordable Care Act health insurance is private individual and family coverage sold through the ACA marketplaces, using guaranteed issue, community rating, a fixed set of ten essential benefits, and income-based premium tax credits.
A little more about this →Advancements in genetic engineering and embryo editing now rest on two mature platforms that do different jobs: base editing, which changes single DNA letters without cutting the double helix, and prime editing, which rewrites short…
A little more about this →Adenovirus F 40/41 is a subgroup of human adenovirus that infects the intestinal lining and causes acute gastroenteritis, most severely in children under 5.
A little more about this →Activities of daily living, or ADLs, are the basic self-care tasks a person must perform to live independently. The six core ADL examples are bathing, dressing, toileting, transferring (moving from bed to chair), continence, and feeding.
A little more about this →The COVID-19 pandemic is the global outbreak of SARS-CoV-2, a betacoronavirus that jumped from animals to humans in late 2019 and spread to every continent within about three months.

A little more about this →ACE inhibitors for dogs are a class of blood pressure–lowering and kidney-protective drugs, most commonly enalapril, benazepril, and lisinopril, used mainly for congestive heart failure, systemic hypertension, and protein-losing kidney…
A little more about this →A ferret blood draw is a minor veterinary procedure in which a clinician collects 0.5 to 3 mL of whole blood, most often from the cranial vena cava, a peripheral leg vein, or the jugular vein, to run a complete blood count (CBC), chemistry…
