Claims checked to the source — full text

Three claims, checked end to end, in full. This is the whole product: no summary of a summary, no headline, no app to install. A $20 check looks exactly like this, only the claim is yours.

Check 1. “Space debris kills one person a year from 2032.” The source says otherwise.

A Swiss radio piece: from 2032, one person dies every year, hit by falling space debris. I tried to find that study. Not in the literature. A telephone game, and the original message is findable.

The real ancestor: a 2021 FAA report to Congress on satellite disposal. By 2035, IF growth is realized and debris survives reentry: casualty expectation 0.6 people injured or killed per year. One every two years, hurt or dead, conditional. The report adds: fully burn up, and the rise could be minimal. 0.6 became 1, 2035 became 2032, “injured or killed” became “dies”.

Byers et al., Nature Astronomy 2022: uncontrolled rocket reentries, 6-10% chance of one or more casualties in the next decade. A 2026 Space Policy study of eleven megaconstellations: about 40% collective casualty risk if they do not burn up.

Ground truth: 70 years of spaceflight, no confirmed death from falling debris. The one confirmed person struck, Oklahoma 1997, walked away.

The risk is real, growing, and lands hardest on the Global South. A risk story, not a death schedule.

Check 2. “There is an explosion in all cancers in young people.” One cancer, not all.

At a Fox town hall, HHS Secretary RFK Jr. said there is “an explosion in all cancers in young people, particularly soft tissue cancers,” and that colorectal cancer, “unknown in children in previous generations,” is now seen “a lot.”

The data says: one cancer, not all.

Children 0-14: 17.3 new cases per 100,000 (2017-2021), down 0.8% a year. Ages 15-39: 77.6 per 100,000, flat (0.3%, not significant). Soft tissue: 1.1 per 100,000, flat to down. No explosion anywhere.

Colorectal is the real signal. Overall US incidence is falling 0.9% a year, but in ages 20-49 it is rising 3% a year, and it is now the leading cause of cancer death in Americans under 50 (ACS 2026). In children under 20 it is 0.3% of all cases: a few hundred diagnoses a year. Rare stays rare even when the ratio grows.

The cause? RFK Jr says “almost certainly” the food, maybe pesticides. The ACS says: “urgent need for etiologic research to discover the cause of the rising trend.” That is the honest sentence.

Check 3. “Scientists’ pay has fallen since 2021.” No. The panel changed.

Nature’s 2026 salary survey, 3,882 self-selecting respondents in 133 countries. The numbers going around: the share earning under US$50,000 a year moved from 38% in 2021 to more than half now, and the share earning $80,000 or more fell from 32% to 22%. Read as a trend, that says pay collapsed.

In the same two editions, respondents from Asia went from 10% to 39%. Nature prints the caveat itself: “this apparent drop in global salaries might be because of geographical shifts in those surveyed.”

Two more things the comparison does not survive. Salaries are self-reported, converted to US dollars by the respondent, then binned. There is no purchasing-power adjustment anywhere in that step, and a dollar buys nearly five times more in India than in the United States, so $15,000 there is roughly $70,000 here (IMF figures cited in the article). Drop three times as many Asian researchers into the panel and the global dollar figure falls without anyone’s pay changing. The article also warns that a national average can be skewed by who answered.

What is established: the squeeze, and it is not small. Less than half of respondents had received a pay rise in the past 12 months. About one-third said their salary covers only basic expenses. One in ten said it does not cover even that. Those are questions about what people can afford, and they do not depend on a currency bin.

So: not a measured fall in pay. A change in who was asked, in a survey that says so on the page.
