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 ...

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 ...

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 ...

White Canes provide low-tech assistance to the visually impaired, but some blind people object to their use because they are cumbersome, fail to detect elevated obstacles, or require long training ...
