Nadia Rahim is a RECATOOLS editorial persona focused on statistics and data literacy: what confidence intervals, averages, correlations and margins of error actually mean, and how they are misquoted. Articles under this byline trace each claim to the primary statistical literature and show the working, so readers can check a number rather than take it on trust.

Mitochondrial DNA does not use the genetic code you were taught

Four codons differ between the standard genetic code and the one your mitochondria use, and two of them are stop signals moving in opposite directions. A mitochondrial gene read with the standard table comes out both too short and too long.

Fukushima Holds 880 Tons of Debris. Crews Have Removed Under a Gram.

Two trial retrievals have brought out 0.887 grams against 880 tons of fuel debris. The grams are not the project; they are the specification for tooling nobody has built yet.

Why your DNA ancestry estimate is vaguer if you are Asian

A result full of "Broadly" labels is telling you something real, but not about your ancestry. One company's own documentation puts 73 reference samples behind maritime Southeast Asia and 2,000 behind Wales.

When a DNA match could be your grandparent or your half-sibling

A match sharing around 1,700 centimorgans could be a grandparent, an aunt or uncle, or a half-sibling. The averages for all three sit within eighteen centimorgans of each other, so the total cannot separate them — but the segment count can.

SpaceX Is Casting Turbine Blades Because Almost Nobody Else Can

A gas turbine is mostly components any industrial economy can build. One part is not, and the queue for it has been quietly rationing how fast data centres can generate their own power.

Caltech Got Fibre-Grade Optical Loss Onto A Silicon Chip

Optical loss is what has kept chip-scale photonics far behind optical fibre. A Caltech group put the fibre material itself onto a chip using standard lithography, reaching quality factors above 180 million.

Why a 1,000-Qubit Computer Has Zero Usable Qubits

Physical qubits and logical qubits are different currencies. At current error rates one logical qubit costs about 1,681 physical ones — so a thousand-qubit machine holds none at all.

What Is a Qubit, Really?

A qubit is not a bit that is both values at once. We built a simulator and measured what actually separates one from a coin: a Bell pair disagreed on 0 of 100,000 shots, while the same qubits left uncorrelated disagreed 49,921 times.

What Actually Decides When Caffeine Wears Off

Coffee at four, still awake at midnight? The usual answer is that a substance is gone after ten half-lives — a tidy number that turns out to depend entirely on two things it never asks you for: how much you had, and how little counts as none. Same coffee, three different answers.

Why Isn't the Periodic Table Sorted by Weight?

The periodic table is not ordered by weight. Walk our own 118-element data from hydrogen to oganesson and the weight falls, rather than rises, in seven places — four of which are the reason the table is arranged by proton count, and three of which are an artefact of one column holding two different quantities.
