For the first time, scientists have reversed a key chemical signature of aging in human tissue—turning back the molecular clock by decades in hours.
In 1997, psychologist Arthur Aron ran an experiment at Stony Brook designed to produce closeness between strangers in under an hour. The 36 questions he built for that lab study went on to become one of the most viral pieces of psychology research ever published — and one pair from the original experiment ended up married.
Lewis Terman's century-long study of 1,528 high-IQ California children was designed to prove intelligence was destiny. It proved almost the opposite — and the traits that actually predicted success were ones he wasn't measuring.
The flat, on-rails feeling of adult weeks isn't really about tiredness or the job. Diary studies and brain research point to a simpler culprit: predictability itself lets the days run without conscious attention, and the brain quietly stops recording them.
Stephen Porges' polyvagal theory identified a third autonomic gear beyond fight-or-flight — a dorsal vagal shutdown that produces eerie composure in the moment and delayed trembling once the person is finally alone.
In the 1990s, neuroscientist Stephen Porges proposed the polyvagal theory: an ancient branch of the vagus nerve pulls the body into stillness when fight and flight are both off the table. Here's how the theory reframed stress, trauma, and the felt sense of safety.
In 1951, British psychiatrist John Bowlby told the World Health Organization that a child's need for closeness was as biological as hunger — and that the calm, undemanding child was often the one who had already learned that asking for less kept the peace.
In 1999, Cornell psychologists David Dunning and Justin Kruger tested undergraduates on grammar, logic, and humor — and found the worst performers rated themselves in the 62nd percentile. The gap wasn't ego. It was a missing internal alarm bell.
Your gut knows things your brain hasn't figured out yet.
Marcus Raichle's PET scans in the late 1990s revealed that a wandering mind isn't idle — it activates the default mode network, a triangle of brain regions that burns energy running memory, planning, and problem-solving in the background.
Buried beneath the cortex, the basal ganglia compress studied routes and rehearsed skills into single automatic packages — chunks that keep firing long after the memory of learning them has faded.
In a 2012 University of Minnesota experiment, Kathleen Vohs sat volunteers in a tidy or messy room and asked them to invent new uses for a ping-pong ball. The messy-room ideas were rated significantly more creative — a small study that has quietly reshaped how psychologists think about desks.
Edgar Mitchell coined a private version of it on Apollo 14 in 1971; Frank White gave it a name in 1987; and in April 2026 the Artemis II crew, flying 406,771 kilometres from Earth, described the same shift in almost the same words.
Scott Kelly and other long-duration ISS crew describe overwhelming smells, painful feet, and a driving sensation that feels remote-controlled after months in microgravity — the nervous system re-learning Earth in real time.
Tetris began as a way to test a computer that could barely draw. In June 1984, Alexey Pajitnov, a researcher at the Computing Centre of the Soviet Academy of Sciences in Moscow, was writing small programs to see what a new machine could do.
The claim arrives fully formed and easy to repeat. A person who loses their sight before about the age of five, it says, dreams without pictures at all.
