Don't hold your breath waiting for rain in the desert. Instead, breathe easy knowing that the desert fragrances after a storm help keep you healthy and happy, according to new University of Arizona research.
Healthy young people with just a mild Covid infection can sometimes suffer temporary post-infection consequences such as tiredness, loss of smell and taste or reduced fertility. These symptoms usually improve with time. But a new UZH study conducted with Swiss Armed Forces personnel shows that young people post Covid are likely to have increased cholesterol, a high BMI, and a reduced level of physical stamina. As a result, they may be more likely to develop metabolic disorders and cardiovascular complications in the long term.
The landmark legislation has evolved significantly over the last five decades, Walker says.
Hot days followed by sweltering nights without any temperature relief in between might become a new norm towards the end of the 21st century. Researchers from the University of Zurich have analyzed the frequency, intensity and length of such extreme events for five Swiss cities. Lugano and Geneva would be most affected.
Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation and survival of complex carbon molecules in space.
The stellar structures are thought to be created when galaxies collide with hot gas in a process that could be likened to doing a belly flop in a swimming pool.
Chronic diseases often lead to fibrosis, a condition in which organ tissue suffers from excessive scarring. Researchers at the University of Zurich have now developed an immunotherapy that specifically targets the cause – activated fibroblasts – while leaving normal connective tissue cells unharmed. If this approach is also found to work in humans, it could lead to an effective treatment for fibrosis.
Mutations in a certain molecule result in severe damage in the structure and mineral composition of tooth enamel in mice, according to a study conducted at the UZH Center of Dental Medicine. The researchers combined genetic, molecular and imaging techniques.
Acoustic communication is not only widespread in land vertebrates like birds and mammals, but also in reptiles, amphibians and fishes. Many of them are usually considered mute, but in fact show broad and complex acoustic repertoires. According to researchers at the University of Zurich, the evolutionary origin of vocal communication dates back more than 400 million years.
Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers at the University of Zurich have now shown that different plant communities in the tundra play a key role in this energy exchange but are not taken into account in climate models.
As heat waves blaze across the United States, a University of Arizona researcher says city planners should take the lead in managing and mitigating extreme heat.
A new study identified a gene variation that could inform clinicians which patients are more susceptible to developing stomach cancer.
Over 100 participants from 18 countries – including UArizona scientists and NASA's UArizona-led NEOWISE mission – took part in the international exercise.
Microsurgery with clips is weighed against coils, stents deployed via catheters.
Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.
Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years – Aniakchak II. In the process, they narrowed down potential dates for the Thera volcano eruption.
To understand the unique experience of Black loss, grief and bereavement, it's necessary to consider the collective grief Black Americans have suffered as the result of America's long history of racialization and racist violence, UArizona researchers say.
Ponds, lakes, rivers and streams cover only a tiny fraction of Earth's surface, yet they are home to a comparatively large number of different species, according to a study led by University of Arizona ecologists. The findings have implications for conservation efforts around the globe.
Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much sleep associated with poorer cognitive performance and mental health, say researchers from the University of Cambridge and Fudan University.
Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say a team of scientists from the University of Cambridge and Imperial College London.
