Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time.
Personalized savings reminders can help boost retirement savings
Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don't save, or you emphasize what they stand to gain if they do.

Two paths, one flux: Trapped ions simulate Aharonov–Bohm interference in a lattice gauge theory
In a new Nature Physics study, researchers demonstrated the Aharonov-Bohm effect in a quantum simulation of a lattice gauge theory using a hybrid trapped-ion quantum computer.
Earth's gravity may have kept the early moon's volcanic heart beating
We typically think of the moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception.

Heavy rain can more than double glacier speeds in Alaska
Glaciers are often thought of as unyielding blocks of ice that slowly carve out the landscape as they move downhill by gravity. But sometimes their slow crawl becomes a surge that sees them move orders of magnitude faster than their usual speed.

Theory predicting an older universe without dark matter or dark energy passes key cosmological tests
An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study.
Why treating soil acidity crop by crop is no longer enough for prairie farmers
To protect their future harvests, Western Canadian farmers need to manage soil acidity across their entire multiyear rotation rather than crop by crop, long-term research from the University of Alberta suggests.
