An expert recreates the voice of a 3,000-year-old mummy

Ear, nose, and throat expert David Howard discusses how his research team extracts vocal folds from preserved human tissue, which allows them to model the deceased person's larynx. From there, they can create a synthetic voice based on the organ's geometry.

Paul Broca, a French brain researcher in the 19th century, hypothesized that humans evolved to trade in our "bestial sense" of smell for higher brain capacity.

A stand-in 'nose' may help people with anosmia to smell certain odors

In a 2025 paper, researchers reported they'd created a proof-of-concept device that bypasses typical olfactory pathways and instead exploits an alternative—the trigeminal nerve in the nose—to detect a few strong scents. The nerve typically helps detect the temperature of inhaled air or the presence of irritants. (Some users may experience a paywall.)

Smell is a robust memory cue for individuals with Alzheimer's disease

Odor is more effective than both visual and verbal cues for triggering autobiographical recall in Alzheimer's disease, according to 2021 research.

Smell retraining can help people with anosmia learn to smell again

Olfactory training, which involves repeatedly smelling a selection of strong odors, teaches your brain to familiarize itself with experiencing smells over a lengthy period, typically multiple months. This can be useful for patients who lose their sense of smell for myriad reasons.

Scientists determine the smells of objects in outer space

Using spectrographic techniques, scientists determine the chemical composition of planetary atmospheres, comets, and other objects in space. Combining these chemicals in labs on Earth has revealed locations in space that smell like nail polish remover, rotten fish, and urine.

Humans may be able to distinguish more than one trillion scents

That's according to one estimate published in 2014. This figure far exceeds earlier estimates of a human smelling ceiling around 10,000 odors. The newer figure is derived from experiments in which volunteers agreed to sniff varying scents. Researchers mixed odor components and had volunteers sniff the brews to detect subtle scent differences. (Some users may experience a paywall.)

Scent is a stronger memory trigger than sight

Smell is imbued with more emotion than visual memories, and research indicates that smell triggers a significantly greater effect on amygdala activation. Scientists believe these powerful responses occur partly because smell signals bypass the thalamus and go directly to the amygdala and hippocampus, brain areas involved in emotion and memory.

Mummification involves drying a body to preserve it long-term

It was a common and respected practice in many ancient societies. The Egyptians perfected the ritual as part of their religious views of death, believing the dead needed to remain physically intact to reach the afterlife. Mummies were common also in ancient China, Mesoamerica, and the Canary Islands.

Olfactory training, a widely recommended treatment for people with long-term loss of smell after a viral infection like COVID, can be performed at home using bottles of essential oils—often lemon, rose, clove, and eucalyptus—to help reorganize neural connections in the brain.

Read a study documenting how 'old people' smell increases with age

Humans can track smells on the ground quite well—our ability to crawl is a limiting factor

As part of a scientific bet, neurobiology researchers dragged a chocolate bar across the grass and sought to see if a human could track it—she could. This led to a more in-depth experiment on human olfactory capabilities and behavior when other senses were blocked.

Mummification in Ancient Egypt transformed a body into a divine statue

Rather than for preservation, the ritual was a means of turning the biological body into an eternal vessel for the top percent of society. With no way to preserve eyes that would shrivel during dehydration, eye sockets were filled with onions or black and white stones.

How a modern 'beer archaeologist' crafts ancient ales

The short documentary follows Travis Rupp, a University of Colorado classics professor who also works with Avery Brewing to produce Ancient Egyptian, Roman, and Peruvian beer.

Without mummies, ancient Egyptians feared their souls would perish

The ancient Egyptians placed major importance on mummification because of their beliefs about the afterlife. They believed a preserved body was essential for the soul’s survival, as it needed a physical form to return to. Without it, they feared the soul would perish.

A particle accelerator allowed researchers to noninvasively examine a mummy

The mummy hailed from the Faiyum oasis, where Egyptian and Roman cultures intersected, and was analyzed using the Advanced Photon Source at Argonne National Laboratory. The device used high-energy X-rays to probe the material composition of numerous objects embedded deep inside the mummy without damaging its remains.

Our sense of smell affects what foods taste like and how we perceive it

Scent stimulates our olfactory sensor neurons high in the nasal cavity, and the brain attaches labels to those scents. But when we eat, chemicals from the foods travel from our mouths and throat to those neurons. We have roughly 400 odor receptors, and they can be used to decipher more than 10,000 different odors (or more than one trillion by some calculations), including the nuances of different foods.

Loss of sense of smell is a common symptom of COVID-19 infection

In 2020, researchers discovered why this occurs. The virus that causes this infection attacks the cells that support smell-detecting neurons. Once infection clears, the sense of smell typically returns, though the exact timeline for that differs by patient. (Some users may experience a paywall.)

A researcher thinks she knows why people keep touching museum exhibits

A museologist who studied unauthorized touch at the British Museum concluded that people may feel it's difficult to learn about things "unless you handle them" and that people are trying to connect with the past, viscerally. Her work has included interviewing British Museum visitors who committed unauthorized touches and spending extensive periods observing people touching prohibited items across 2004 and 2005.

Whose bodies are held inside the American Museum of Natural History?

The American Museum of Natural History holds the remains of at least 12,000 people collected via purchase, donation, or expedition. This article by a professor of art crime details their attempt to identify the individuals whose remains the museum held. Amid questioning, AMNH announced it would change its human remains policy. At the time of the article's publication in October 2023, AMNH had few human remains on public display.

Humans can't smell the inside of their nose due to olfactory fatigue

Once a person is accustomed to a specific odor, their neurons have trouble continuing to respond to that smell because of that familiarity. That's why humans may not notice when their house smells like trash until they leave the house and then return to it.
