The roundworm uses cues from visible light to help avoid eating toxic bacteria with a distinguishing hue.

Neurological representations of different tastes—like those of different smells but unlike those of sight, hearing, and touch—do not cluster in distinct spots within a murine brain region, a study shows.

Take a break from the bench to puzzle and peruse.

Using optogenetics, scientists have simulated the sense of smell directly within the mouse brain to investigate the nature of olfactory perception.

A major sensory neuron in roundworms distinguishes proprioception from harmful touch by sending out local or whole-cell signals, respectively.

A study identifies five women who have a functioning sense of smell despite an apparent lack of olfactory bulbs—the region of the brain that processes odors.

Hear the muted symphony that one researcher thinks might be a close approximation to how macaques perceive the performance.

Thicker calluses don’t dull sensitivity in feet.

Bats move their ears fast to create frequency shifts in echoes that can give them more information about their prey targets or the surroundings they are navigating through.

A new book about remarkable feats of migration by animals explores the front lines of research into how they do it.

Weird effects on the scale of subatomic particles may play roles in enzyme catalysis, photosynthesis, and avian magnetoreception.

An experimental hearing aid differentiates speakers and monitors the wearer’s brain activity to amplify the one she is trying to listen to.

Neural networks generate abstract images designed to activate particular cells, lending insight into their function.

A study of people’s brainwaves hints at their unconscious ability to perceive the Earth’s magnetic field.

Authors of a small study say the two abilities likely evolved in tandem.
