As a result of the climate crisis, future forests may become unrecognizable. Trees that currently make up European woods may no longer be seen — or they may have moved several hundred meters uphill. Scientists writing in Frontiers in Forests and Global Change have mapped the forests of five vulnerable mountain areas in Italy and modelled the future of these fragile ecosystems. “If I imagine my daughter walking with me as an old man, in our mountain forests, I can imagine that we can see the initial stage of a profound ...

Children have loved Disney princesses since Snow White and the Seven Dwarfs premiered in theaters in 1937. While this adoration continues to grow in terms of princess movie ratings, some parents may wonder what effects these idealized images of young women might have on how their children feel about and express themselves.  According to new research from the University of California, Davis, a favorite princess improved — but did not harm — young children’s ...

The observatory has been used to document the transport of Saharan dust particles across the Atlantic Ocean to the Caribbean, creating the longest-running dust data set in existence. Scientists from many different disciplines use the data to understand how dust particles impact everything from coral reef health to cloud formation and tropical storms. Through a grant from the National Science Foundation (NSF), the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science recently completed a major upgrade to its Barbados Atmospheric Chemistry Observatory (BACO), expanding its capability ...

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane — a greenhouse gas — into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays. Methane is also released when organics-rich permafrost thaws as the result of heat carried by the spreading water. A study linking Arctic beavers to an increase in the release of methane was ...

Australia’s employment laws and regulations must be updated to reflect the changing nature of work, with many people continuing to work from home long after the COVID-19 pandemic. That’s according to University of South Australia Associate Professor of Organisational Behaviour Dr Ruchi Sinha who says labour laws and protections should be updated to clarify issues related to work hours, overtime, and breaks in a remote work context, now that almost half of all employees are working from home at least once a week. The Australian Institute of Health and Welfare ...

Milan, Italy: Women exposed to air pollution give birth to smaller babies, according to research that will be presented at the European Respiratory Society International Congress in Milan, Italy [1]. The research also shows that women living in greener areas give birth to bigger babies and this may help counteract the effects of pollution.   There is a strong relationship between birthweight and lung health, with low birthweight children facing a higher risk of asthma and higher rates of chronic obstructive ...

Asian Americans are among the fastest growing populations in the U.S. but are significantly underrepresented in Alzheimer’s disease and related dementias (ADRD) research. This means there is a significant knowledge gap of ADRD in this particular group at a time when the global Asian population is rapidly aging and the burden of ADRD will likely mirror this growth. Thanks to a new award, the Keck School of Medicine of USC’s Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) is perfectly poised to help bridge the gap.  Professor of ...

New Haven, Conn. — Music can take on many forms in cultures across the globe, but Yale researchers have found in a new study that some themes are universally recognizable by people everywhere with one notable exception — love songs. “All around the world, people sing in similar ways,” said senior author Samuel Mehr, who splits his time between the Yale Child Study Center, where he is an assistant professor adjunct, and the University of Auckland, where he is senior lecturer in psychology. “Music is deeply rooted in human social interaction.” For ...

A new study by University of Maryland Economist Louis Preonas provides empirical evidence that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources. One strategy being considered to help reduce the country’s contribution to global climate change is a tax or fee on greenhouse gas emissions by coal-burning power plants. The hope is that such fees will reduce competitiveness of coal-fired energy and consumers will chose lower-emission options at a competitive cost. The new study, published September 7, 2023, in The ...
