Geosmin is a volatile compound of microbial origin with a distinct 'earthy' to 'musty' odor that can affect the quality of water and food. A research team has now identified and characterized the human odorant receptor for geosmin for the first time. Geosmin is a volatile compound of microbial origin with a distinct "earthy" to

A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections. The lightning-fast development of COVID-19 vaccines just months after the virus appeared was a triumph of modern

Scientists uncover 'striking' immune cell populations poised to fight SARS-CoV-2 in upper airway. Scientists at La Jolla Institute for Immunology (LJI) have published the first-ever, in-depth analysis of immune cell memory in the upper airways of adult volunteers. Among these immune cells, the researcher spotted "tissue resident" memory cells, which stand ready to defend the

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance. Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder

A new study provides evidence that a spillover of avian influenza from birds to dairy cattle across several U.S. states has now led to mammal-to-mammal transmission -- between cows and from cows to cats and a raccoon. A new Cornell University study provides evidence that a spillover of avian influenza from birds to dairy cattle

Scientists have discovered how the dangerous Respiratory Syncytial Virus (RSV) defuses our immune response and, in doing so, they have pinpointed an exciting new target for drug developers. Irish scientists led by a group from Trinity College Dublin have discovered how the dangerous Respiratory Syncytial Virus (RSV) defuses our immune response and, in doing so

A study helps explain why dairy cows infected by highly pathogenic avian influenza are shedding the virus in their milk. Their findings could help develop biosecurity measures aimed at slowing the spread of the illness. As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw

Vaccinating mothers against respiratory syncytial virus (RSV) during late pregnancy to protect their newborns is not associated with an increased risk of preterm birth or other poor outcomes. Infants are particularly vulnerable to the virus which can cause a serious lower respiratory illness. Vaccinating mothers against respiratory syncytial virus (RSV) during late pregnancy to protect

While H5N1 avian influenza virus taken from infected cow's milk makes mice and ferrets sick when dripped into their noses, airborne transmission of the virus between ferrets -- a common model for human transmission -- appears to be limited. These and other new findings about the strain of H5N1 circulating among North American dairy cattle

American Society for Microbiology. The study found that the composition of nasal microbiota can serve as a reliable indicator for sepsis, potentially revolutionizing early detection and treatment in ICU patients. This groundbreaking research highlights the potential of nasal microbiota analysis as a pivotal tool in the fight against sepsis, offering a more accurate and efficient method for predicting and managing this life-threatening condition

Symptoms, a new study finds. The study reveals that the nasal cells of young people have a stronger immune response to the virus compared to older individuals, potentially leading to less severe symptoms in children. This discovery provides crucial insights into the varying effects of COVID-19 on different age groups and could inform future research and treatment strategies. Understanding the unique immune responses in different age groups is essential for developing targeted interventions and improving public health responses to the pandemic

Episodes of paroxysmal supraventricular tachycardia (PSVT). This convenient at-home treatment option has the potential to revolutionize the management of this common heart rhythm disorder, offering patients a simple and effective way to manage their condition outside of a healthcare setting. With its proven safety and efficacy, etripamil represents a promising alternative for patients seeking greater control and autonomy in managing their heart health
