Federal surveys found 45 percent of public schools with open teaching posts in 2022; the evidence blames low pay, weak support, and burnout, and points to two kinds of fixes.
Newsroom choices run on news values and inherited framing: a 2021 study found 69.5 percent of headlines on mouse studies dropped the mice, and a 2026 experiment tested a fix.
Clear writing has tools, dates, and laws: Flesch-Kincaid in 1975, the Plain Writing Act in 2010, and an ISO standard in 2023. Here is what the evidence shows.
Reading aloud is the core of clinic literacy programs that hand families books. A 2023 review and a 2026 randomized trial document more reading days at home and real language gains.
Citation-mapping tools trace a paper backward to its foundations and forward to its offspring. Here is what they can and cannot tell you.
A clear argument, an honest methods section and a limitations paragraph you are proud of will do more for a paper than any clever phrase.
An autonomous shotgun and a blood recirculation machine are both in development at the Air Force Research Laboratory. What the reporting supports — and what it does not.
A nine-story lab building is a promise, not a result. Here is what the numbers in such announcements can and cannot tell you.
Why landmark results sometimes collapse when other scientists repeat them, and what open science is doing about it.
Adult literacy programs deliver real but small reading gains. A 2011 trial of 198 adults, UNESCO’s 2025 count, and PIAAC surveys show what the evidence supports.
Youth science news is its own journalism. One newsroom has rewritten research for readers as young as nine since 2003, tuning vocabulary and adding teacher aids without weakening the reporting.
Dual-language classrooms are often praised and often doubted. The honest picture is more measured than either camp suggests.
Incremental change fills in the gaps; disruption starts cheap and grows. Schumpeter’s split and Christensen’s 1995 theory, with the case that broke its own rules.
A Charlotte training center shows why device innovation fails in the operating room when nobody practices the whole setup.
A new thing is not an innovation until someone uses it and value moves. The definition is stricter than the marketing suggests.
Why some of the world's most useful devices come from tight budgets, and what the word 'frugal' actually carries into engineering.
The literacy rate in the US is a skill ladder, not a pass-fail count. What the 2023 federal numbers show, and why method changes blur the trend.
Decades of research point to one skill at the center of learning to read — and it explains why classrooms keep changing.
National tests show a real reading slide: 31 percent of fourth-graders at Proficient, more adults at the lowest levels. The crisis label depends on the bar.
Two groups, one bold headline, and a hidden factor nobody mentioned. Learn how confounding and selection bias make studies compare apples to oranges, and how to spot it yourself.
Scientists host most science podcasts, listening hit record shares of Americans in 2024, and the first big census of the genre traced its climb from 2004 to 2018.
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.
Fossils are almost never dated directly. Geologists date the rock around them instead, and the method depends entirely on what happens to be nearby.
Schools run on three streams: local property taxes, state aid, and a small federal share. The mix explains most gaps between districts, and the spending record is humbling.
The word shows up in every school brochure. Here is what it actually means, and how to tell a real change from a renamed one.
The standardized testing debate is really a question about fairness: same exam for everyone, but is the same exam measuring the same things?
The committees that protect study volunteers also add months to timelines. The trade-off is deliberate, but the delays have grown.
