Locusts can differentiate between cancer cells and healthy cells, research shows

Researchers at Michigan State University have shown that locusts can not only "smell" the difference between cancer cells and healthy cells, but they can also distinguish between different cancer cell lines.

3D models of cranial endocasts help better understand brain evolution of lungfishes

The evolution of the brain and nervous system in animals has been wound back more than 400 million years, thanks to the examination of fossil remains of ancient lungfish providing a missing link in the emergence of land-living, four-legged animals on Earth.

Can dogs accurately detect COVID-19?

Researchers evaluate the accuracy of using dogs to smell and identify the presence of SARS-CoV-2 in infected and non-infected individuals.

RGS2 protein expression may explain reduced sense of smell in COVID

Researchers tested the hypothesis that anosmia in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals elevates the expression of the odorant receptor, a regulator of G protein signaling 2 (RGS2) in humans.

Dogs can detect SARS-CoV-2 from an individual's sweat

In a recent study published in the Open Forum Infectious Diseases (OFID) Journal, researchers reported that severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) could be detected by canine olfaction.

COVID-19-induced non-cell-autonomous anosmia

Researchers reported that SARS-CoV-2-induced anosmia was based on non-cell-independent processes.

Rapid and cheap test for dysosmia in COVID-19

A new study discusses the potential utility of using paired ampules of n-butanol to screen for COVID-19 and detect those at greater risk for severe illness.

Study identifies olfactory dysfunction as an early symptom of COVID-19

In a new study, scientists researched olfactory loss and dysfunction among COVID-19 patients to objectively characterize it as a symptom of COVID-19.

Sniffer dogs detect long COVID after 1.5 years

Researchers used sniffer dogs to test the presence of SARS-CoV-2 infection in axillary sweat samples of long COVID-19 patients.

Scientists find infection of sustentacular cells in the olfactory epithelium of COVID-19 patients

It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure.

For older adults, smelling the roses may be more difficult

The reports from covid-19 patients are disconcerting. Only a few hours before, they were enjoying a cup of pungent coffee or the fragrance of flowers in a garden. Then, as if a switch had been flipped, those smells disappeared.

SARS-CoV-2-related smell loss lasts longer than previously thought

A recent study discusses the long-term prevalence of olfactory dysfunction in COVID-19 patients.

COVID-19 and loss of sense of smell

A recent review examines the high susceptibility of the olfactory epithelium to SARS-CoV-2 infection.

“Catching SARS-CoV-2 in the act” – viral infection of nasal mucosa spares nerve cells

A new study discusses the entry of SARS-CoV-2 into the respiratory and olfactory mucosa of the nasal cavity.

New method to diagnose anosmia

In a recent study, researchers discuss a new method of tracking the Nav1.7 channel to reduce the reliance on more invasive diagnostic measures.

Light exposure during pregnancy may be linked to fetal brain development

There may be a link between exposure to light during pregnancy and fetal brain development. New findings by researchers at Umeå University, Sweden, working in collaboration with American colleagues, may provide better understanding of certain neurological diseases later in life.
