New research links poor sense of smell in older adults with higher risk of getting pneumonia.

Light and sound move at different speeds. To make sense of the sights and sounds around you, your brain has a few tricks to account for the difference.

New findings advance the understanding of sensory processing sensitivity, a trait that an estimated 1.4 billion people worldwide share.

Researchers have found taste cells in mice that respond to as many as four different tastes. Humans are likely to have the same cells, the researchers say.

"People use pigs for finding truffles. It's a similar approach—using a biological organism—this is just a bit more sophisticated."

Researchers have created a model of the brain that may clarify how the sense of smell actually works. It also mirrors insect brains.

Virtual reality is great at taking users on a visual journey. But it's not so good for simulating touching objects. A new device could change that.

After relocating to islets with no predators, Aegean wall lizards changed the chemical signals they use to communicate with each other, researchers say.

Your skin is smarter than it may seem. Rather than just gather data on touch, skin actually helps process that information, researchers say.

Multiple opsin proteins, known for decades to be required for vision, also function as taste receptors, new research with fruit flies finds.
