By comparing their results to different models of the Earth's interior, Professor Tkalčić and Dr Ma found that this was best explained by the presence of a vast underground 'torus', or donut ...

In the end, we found there must be a torus—a donut-shaped region—in the outer core around the Equator, where waves travel more slowly. Seismologists have not detected this region before.

Whenever the rat is actively exploring and navigating the world, its sensory system has to coordinate and align the internal grid cell pattern, the torus map, with the external environment.

Using data collected by NASA's Juno spacecraft as it flew past Jupiter's highly volcanic moon Io in late 2023 and again in ...

doughnuts laced together like links of a chain. The central horizontal torus (scientific word for a doughnut shape) is a ring-shaped aluminum vacuum chamber with a 39-in. bore. The two vertical ...

Physicist Glenn Starkman and his team propose it could have a complex topology, possibly shaped like a 3-torus, resembling a hyperdimensional doughnut. The cosmic microwave background (CMB)—a ...
