A Canadian-led study is adding new weight to the idea that Earth’s deep interior can influence something as familiar as the length of a day. Researchers say gravitational interactions within the planet may be driving slow, multidecadal shifts in how long Earth takes to rotate, a finding that could refine models used in climate science, geophysics and precision timekeeping. The work underscores how processes far below the surface can ripple outward into systems that underpin modern infrastructure and scientific measurement.

A new study suggests that Earth’s deep mantle may have stored and later released excess oxygen through magma processes, offering a fresh explanation for how the planet’s atmosphere became oxygen-rich. The findings add a new layer to the long-running debate over the Great Oxidation Event and the role of ancient weathering, volcanism and mantle chemistry in shaping Earth’s habitability.

New research on ancient footprints preserved at White Sands in New Mexico suggests humans were present in North America about 23,000 years ago, during one of the harshest climate intervals of the Ice Age. The findings strengthen the case that early Indigenous people endured dramatic environmental instability, adding fresh urgency to debates over how climate stress shaped migration, settlement, and survival in the Americas.

Researchers have developed an “invisible” tattoo ink that can be switched on and off under different light conditions, opening a novel path for secure marking, anti-counterfeiting and bioresponsive design. While the technology is still early, it highlights how materials science is converging with optics to create surfaces that can change appearance on demand.
