Scientists recently voted to designate Crawford Lake, a small body of water in southern Canada, as the reference site of the “Age of Man.”
Researchers working on Hawaiian mountain tops precisely synchronized two clocks with unprecedented efficiency, demonstrating the potential to create networks of such clocks for geodesy and more.
High humidity and low temperature altered COVID-19 spread in Brazil, but only slightly.
Los calendarios de horizonte fueron clave para medir el tiempo para las culturas pre-hispánicas de la cuenca del Valle de México. Un nuevo estudio sugiere que los calendarios se usaron para gestionar los ciclos agrícolas.
Horizon calendars were a key part of time measurement for pre-Hispanic cultures in the Basin of Mexico. A new study suggests that calendars were used to manage the agricultural cycle.
The Moon was a lot closer to Earth 2.46 billion years ago, and the shorter distance contributed to shorter days.
Tiny magnetometers have turned your phone into a compass, and new research shows they are sensitive to geomagnetic storms.
Using cosmogenic nuclide dating, scientists determined a 10-meter core just below the surface to be over a million years old.
Atomic clocks are now so accurate that Earth’s gravity can be seen to slow them down. Geodesy is preparing to use this relativistic effect to measure elevation.
When calibrating satellite observations with ground-based ones, estimated precipitation rates are improved by considering that snow takes longer to fall compared to rain.
