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.
Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.
Microsurgery with clips is weighed against coils, stents deployed via catheters.
Over 100 participants from 18 countries – including UArizona scientists and NASA's UArizona-led NEOWISE mission – took part in the international exercise.
A new study identified a gene variation that could inform clinicians which patients are more susceptible to developing stomach cancer.
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.
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.
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.
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.
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.
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.
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.
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.
The landmark legislation has evolved significantly over the last five decades, Walker says.
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.
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.
Sophisticated simulations of climate during the onset of the last glacial period – some 100,000 years ago – may help explain why a massive ice sheet formed in Scandinavia despite its comparatively mild climate.
It's often true that the better that scholars know their subject, the more unclear their writing is to readers. A research team from the University of Arizona Eller College of Management may be able to help.
A concept developed by University of Arizona aerospace experts and a NASA planetary scientist takes inspiration from albatross flight to learn more about the Red Planet's atmosphere and geology.
A University of Arizona-led team discovered that as the Colorado River carved the Grand Canyon, it flushed away ancient deep saline groundwater. The methods the researchers developed to determine the age of groundwater could be used to date and understand the conditions of deep groundwater elsewhere.
