Scorching Storms on Distant Worlds Revealed
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system.
New U of T Engineering Study Identifies Sources of Indoor Air Pollution in Toronto Subway System
A team of University of Toronto researchers, led by Professor Greg Evans (ISTEP, ChemE) and Keith Van Ryswyk (ChemE PhD 2T3), is working to better understand the sources of air pollution in the Toronto Transit Commission (TTC) subway system — an important first step towards improving its indoor air quality.
New geological datings place the first European hominids in the south of the Iberian Peninsula 1.3 million years ago
One of the most important controversies about human evolution and expansion is when and by what route the first hominids arrived in Europe from the African continent. Now, geological dating techniques at the Orce sites (Baza basin, Granada, Spain) place the human remains found in this area as the oldest...
Complex impact of large wildfires on ozone layer dynamics
In a revelation highlighting the fragile balance of our planet's atmosphere, scientists have uncovered an unexpected link between massive wildfire events and the chemistry of the ozone layer. Using satellite data and numerical modeling, the team discovered that an enormous smoke-charged vortex nearly doubles the southern hemispheric aerosol burden in...
2023 Rolling Hills Estates landslide likely began the winter before
Landslides triggered by intense rainfall can sometimes be predicted along with incoming storms, but dry-season landslides often take people by surprise. The July 2023 Rolling Hills Estates landslide that destroyed 12 homes seemed to come out of nowhere, but new research shows it began as early as December 2022. Researchers...
How domestic rabbits become feral in the wild
After sequencing the genomes of nearly 300 rabbits from Europe, South America, and Oceania, researchers found that all of them had a mix of feral and domestic DNA. They say this was not what they had expected to find.
High and low tide cause low and high methane fluxes
Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.
