Why institutional review boards slow down research (and why that matters)
The committees that protect study volunteers also add months to timelines. The trade-off is deliberate, but the delays have grown.

What a p-value actually means (and what it doesn't)
A p-value is the probability of data at least as extreme as the observed data if the null hypothesis were true — not the probability that the hypothesis is true, and not the size of the effect.

The semaglutide heart trial that changed the obesity-drug conversation, in close-up
The SELECT trial, published in the New England Journal of Medicine in 2023, found semaglutide cut major cardiovascular events by a fifth in adults with existing heart disease and overweight — a benefit independent of diabetes.

How peer review works, and what it doesn't catch
Peer review is a check by outside experts on a study's methods and reasoning before publication — a filter that improves papers but cannot verify data, replicate results, or catch deliberate fraud.

How does peer review actually work before publication?
Before a scientific claim reaches print, an editor and a small group of outside experts read it first — a filter meant to catch errors, not to guarantee a finding is correct.

When animal studies fail to translate
Animal research is an indispensable early filter, yet the large majority of promising animal results never become useful human therapies, and the reasons are structural.

What makes an observational study strong
Observational studies vary enormously in quality; their strength is decided by confounding control, timing of measurement, and whether the design matches its causal question.

How conflict of interest disclosures work
Disclosures are standardized statements of financial and personal ties, built to reveal influence before readers judge the work, and they work only when asked for and checked.

A brain implant let one ALS patient talk for two years at home
A 2026 study in Nature Medicine tracked a man with ALS using a brain-computer interface independently at home for nearly two years — a long-term, single-participant test of whether such systems can work outside the lab, not yet a device anyone else can buy.

How do scientists know how old a fossil is?
Fossils are almost never dated directly. Geologists date the rock around them instead, and the method depends entirely on what happens to be nearby.

Peer review may catch less bad science than readers assume
A 2025 analysis in PNAS finds reviewers often disagree with each other — and shows which specific fixes actually help.

Why pulling carbon from air still costs so much
Direct air capture fights thermodynamics before it fights economics: carbon dioxide is vanishingly dilute in air, and every ton collected must be paid for in energy, materials, and machines.

How the newest antibiotics attack bacteria that resist the old ones
After decades of near-silence, new antibiotic classes are reaching patients — not by overpowering resistance, but by finding targets the older drugs never touched.

What single-cell sequencing reveals about tissues that old tools missed
By reading gene activity one cell at a time, researchers discovered that 'identical' cells differ in ways that average measurements had smoothed away — reshaping how disease is classified.

Why one study is never the last word
Science is cumulative by design: single findings are provisional by default, and the checks that confirm or retire them take time.

Why ocean heat content is the climate number to watch
Roughly ninety percent of the excess energy trapped by greenhouse gases ends up in the sea — and a global fleet of autonomous floats, plus satellite altimetry, measures it.

How JWST's deep fields scrambled the early-galaxy timeline
Since 2022, infrared surveys have turned up galaxies that appear surprisingly bright and mature within a few hundred million years of the Big Bang — and cosmologists are still arguing about why.

How does a federally funded lab discovery become a company?
The Bayh-Dole Act of 1980 set the route from federal grant to patent to licensed startup — and federal records track the paperwork far better than the outcomes.
