BlogsPublication is researched, written, and edited by a small team. We work from primary sources and link to them, a human editor is responsible for everything we publish, and we note substantive corrections on the article itself. Where AI tools help with research or drafting, a person still verifies the result before it runs.
4.54 billion years, give or take 50 million. The strange part is that the number comes from meteorites rather than Earth rocks — and the reason why is the most interesting thing in the whole story.
A vaccine is a training exercise: it shows your immune system a recognisable fragment of a pathogen without the pathogen. Here is the actual biology — antigens, memory cells, why boosters exist, and where the herd-immunity threshold number comes from.
Most food spoils early for one of three reasons: ethylene, moisture, or the wrong temperature. Once you can tell which is which, storage stops being a list of rules to memorise — and 'best before' stops throwing away good food.
Adults are not worse at learning languages than children — they are worse at one specific part of it, and better at several others. What the research says about the critical period, how many words you actually need, and how long it takes.
Jet lag is a clock problem, not a tiredness problem — which is why sleeping more does not fix it. Light is the strongest lever you have, but get its timing wrong and you will push your body clock further from where you want it.
Seven hours is a floor, not a target, and the 'I only need five' claim is almost always wrong. What the sleep-medicine consensus says, why cutting an hour costs you mostly REM, and how to find your own number.
The RDA of 0.8 g/kg is a deficiency floor, not an optimum — and the research on muscle gain converges on a ceiling around 1.6 g/kg, above which more protein does essentially nothing. What the numbers mean for you.
150 minutes a week plus two strength sessions is the global guideline — but the dose-response curve says the most valuable exercise you will ever do is the first 20 minutes, not the last. What the WHO recommends, and where 10,000 steps came from.
Three to six months is the standard answer, and it is the wrong shape of answer. The right size depends on how correlated your income is with the thing that would go wrong — and where you keep it matters as much as how much.
Between 40°F and 140°F bacteria can double every 20 minutes. But the famous 165°F for chicken is not a magic threshold — it is one point on a time-and-temperature curve, and understanding that changes how you cook.
Someone who saves for ten years and stops can finish ahead of someone who saves for thirty years and starts late. Here is the arithmetic behind that, the Rule of 72, and why a 1% fee quietly costs you a quarter of your pot.
Travelling carry-on only is not about packing cleverly. It is about deciding, once, that you will do laundry — after which a two-week trip needs the same bag as a four-day one.
