Word counts across 38,467 songs by 230 popular artists show positive emotion and social words mostly sliding within careers and across generations, though anxiety words crept up. The pattern is an association, not a cause.
SRSF1 is a protein that helps cells edit RNA before using it to make proteins. Its best-known job is RNA splicing, the process that removes unneeded sections from a new RNA copy and joins the useful pieces together. By helping decide which pieces stay and which go, SRSF1 can change the final instructions a gene sends to the cell. Scientists have also linked SRSF1 to cancer, development, fertility, liver health, blood-vessel growth, and, more recently, aging.
Across three online experiments with 1,563 people, reading a careless repairman’s private thoughts rather than his spoken apology raised forgiveness only when he was clearly at fault, and the gains were small.
A lone attacker may be blocked by cutting off information and materials, but a state program mostly can’t be and has to be deterred instead. A policy analysis lays out nine layered defenses to cover both.
Five climate scientists reviewed three decades of fingerprint research and say rainfall, ocean, snow and stratosphere records now point the same way, while conceding that attributing individual extreme events remains hard.
Oral rinses and sputum from 771 patients hospitalized with Covid-19 revealed lopsided microbial communities in the worst long Covid cases, with extra lactic acid producers. Whether those shifts predate infection remains unknown.
Three randomized online experiments with 1,222 participants found that people who lost a chatbot’s help solved fewer fraction and reading problems than people who never had it. Direct-answer users fared worst, though that comparison was not randomized.
Once resets outnumbered scrambling steps, a 100-qubit quantum circuit tipped into control, though a cheaper classical model reproduced the average result. Nothing in the experiment corrected an error.
Adults with chronic low back pain showed higher blood flow in two midline brain regions during a flare-provoking leg raise, but the study had no pain-free comparison group and tested no treatment.
Bedsharing did not measurably reduce sleep duration or efficiency in this small Ontario sample, while multiple-dog owners rated their sleep worse and paired motion traces often moved together.
A scoping review of 327 studies on food vendors in 64 countries found definitions split by licensing, location and stall type, each likely to steer policy differently, while vendors’ own health, bribery and safety stayed thinly studied.
In one 16-year-old with highly superior autobiographical memory, unbidden memories of his past made up 87% of his stray thoughts in a dull lab task, against 39% in 36 comparison adults. One case cannot say why.
