A way of estimating more accurate distances to the thousands of so-called "planetary nebulae" dispersed across our Galaxy has just been announced by a team of three astronomers based at the University ...

The neural circuits that underpin spatial navigation in mammals, birds, and reptiles are well known, but it was unclear whether similar structures also existed in fish. This knowledge would allow us ...

Social insects, which don’t have very large nervous systems, are capable of remarkably sophisticated behavior, such as the direction-giving dance by bees or the lifesaving rafts formed by fire ants.

Humans can estimate distances to sound sources better when they move and exploit auditory motion parallax. The ability to estimate distances to sound sources accurately can be crucial for survival. A ...

Cepheid variable stars exhibit regular pulsations whose period directly correlates with their intrinsic brightness (absolute luminosity). The Leavitt law establishes this relationship between ...

We show that error distributions of a compilation of 28 recent independent measurements of the distance from the Sun to the Galactic center, R₀, are wider than a ...

Rapidly stretching and advancing the initial attack line is critical to the success of any engine company. Upon arriving on scene, the company officer must swiftly and thoroughly evaluate the length ...
