Microscope image of a cross-section of a mouse nose. The animal was genetically altered so that its nerve cells used for smell glow green. Some dying nerve cells appear red.

Scientists Create the First Detailed ‘Smell Map’ of Odor Sensors in the Mouse Nose—and Sniff Out Some Surprising Discoveries

In two new studies, researchers used genetic techniques to upend a longstanding assumption that nerve cells with scent detectors were randomly arranged. They don’t know whether the same spatial organization is found in human noses

More than 95 percent of the world’s bergamot oil production is concentrated in Southern Italy’s Calabria region. But harsh conditions driven by climate change threaten that supply.

Earth’s Smells Are Disappearing Because of Climate Change, and It’s a Vast Cultural Loss

A triple threat of pollution, extinction and warming temperatures is altering the way the planet smells. Scientists are only beginning to understand the stakes for humans

An elephant has about 1,000 whiskers on its trunk.

An Elephant’s Trunk Is Covered in Whiskers—and They’re Unlike Those on Any Other Animal, a New Study Suggests

The carpa uasi served as the bottom level of this building. It originally ended to the left of the arch.

This Inca Building—the Only Surviving Structure of Its Kind—Might Have Been Designed to Amplify Sound and Music

Researchers will use 3D modeling to assess what the “carpa uasi” in Huaytará, Peru, originally looked like and how sound traveled through it

Our Teeth May Descend From Sensitive Bumps on Prehistoric Fish Armor, New Research Finds

Hundreds of millions of years ago, fish had sensory features on their exoskeletons that contained dentine, the material that makes our teeth sensitive today

New research is revealing how climate change is impacting our eyes.

Climate Change Is Threatening Eye Health in Disturbing Ways

Cataracts, pinkeye and other ocular disorders are linked to heat, air pollution and higher UV exposure

The scientists recorded dozens of scents, which they broke down into four categories, including embalming ingredients and odors from plant oils used by modern museum conservators.

Discover the Aromas of Ancient Egyptian Mummies, From Orange Peels to Pine to Incense

A new, first-of-its-kind analysis of the scents of nine mummies detected woody, spicy, herbal and rancid notes, among other odors

Elephants, bats, rabbits and other mammals have exceptional hearing—and their outer ears may be a key reason why.

Why Do Mammals Have Outer Ears? Scientists Are Getting Closer to Solving the Mystery

Two new studies offer insights into the evolution and development of external ears, which appear in humans and other mammals but aren’t found in reptiles, birds or amphibians

You Can Actually Smell the Incense, Rainy Meadows and Musty Cloth in These Pre-Raphaelite Paintings

At an exhibition in England, curators have placed artworks alongside diffusers that dispense carefully crafted fragrances, which visitors can trigger by pushing a button

The lack of a sense of smell, called anosmia, can be congenital or acquired at some point in a person's lifetime.

New Research

People Born Without a Sense of Smell Have Different Breathing Patterns, Study Finds

Study participants with lifelong anosmia sniffed less than those with a normal sense of smell. Future research could shed light on whether this has negative implications for their health

A buff-tailed bumblebee (Bombus terrestris), one of the species found in a recent study to have a diminished sense of smell after exposure to heat.

Heat Waves Can Make Bumblebees Lose Their Sense of Smell, Study Finds. Here’s Why That’s a Problem

Female worker bees, which forage for the whole colony, struggle more to detect scents in the heat than males do, per the recent research

In the Earth’s Quietest Room, You Can Hear Yourself Blink

Background noise in the custom-built chamber is actually measured in negative decibels, which means it’s below the threshold of human hearing

To create mouse-rat "chimeras," researchers injected rat stem cells into mouse embryos that lacked some genes for brain development.

Researchers Breed Mice With Hybrid Brains Containing Cells From Rats

In one experiment, rat neurons helped mice restore their senses of smell—the first time any animal has perceived the world through the sensory hardware of another species

The solar eclipse’s path of totality stretches across North America in a roughly 115-mile-long band, from Mexico to Canada.
