A new study in the Zoological Journal of the Linnean Society co-authored by Yale anthropologist Eric Sargis finds that the barking hyraxes are a separate species from their shrieking neighbors. The newly described species, Dendrohyrax interfluvialis, populates the wet and dry forests that lie between the two rivers in coastal regions of southeastern Ghana, southern Togo and Benin, and southwestern Nigeria. The researchers based their conclusion on the distinctive calls combined with anatomical and genetic differences they identified among tree hyrax populations.
Events of the past year have exposed the crisis of the nation's digital divide. To tackle this problem, Michigan State University researchers have developed a new tool to smooth the collection of federal broadband access data that helps pinpoint coverage gaps across the US.
Researchers from the Department of Mechanical Engineering at the UPV/EHU are studying and optimising the mechanical and thermal properties of new mortars and concrete made using industrial by-products, such as lime mud from the paper industry, brass fibres and furnace slag, with the aim of reducing the consumption of energy and natural resources and fostering the circular economy.
Indigenous Māori people may have set eyes on Antarctic waters and perhaps the continent as early as the 7th century, new research published in the peer-reviewed Journal of the Royal Society of New Zealand shows.
The world is filled with myriad sounds that can overwhelm a person with relentless acoustics. Noise is so prevalent in everyday life that the concept and achievement of comfortable quiet is hard to define. During the 180th ASA Meeting, Aggelos Tsaligopoulos from the University of the Aegean will describe how quiet could be measured in the hopes of better understanding its impact on people. The session, "Towards a new understanding of the concept of quietness," will take place Wednesday, June 9.
Cities located in metropolitan areas of this Brazilian state score better according to an index that measures the existence of public policies designed to adjust critical sectors to the impacts of climate change.
Due to strict lockdowns, many of us have seen and heard our family and neighbors much more than ever before. During the 180th ASA Meeting, Ayca Sentop Dümen and Konca Saher from the Turkish Acoustical Society will discuss the effects of pandemic-related noise on people's satisfaction with their homes and how this may inform future design choices. Their presentation, 'Noise annoyance in dwellings during the first wave of Covid-19,' will take place Tuesday, June 8.
Published in a Nature journal, an unprecedented UN analysis of 9,500 Harmful Algal Bloom (HAB) events recorded globally over 33 years shows harm rising in step with the aquaculture industry, marine exploitation and coastal development. 109 scientists in 35 countries conducted the 7-year study and report HAB events have increased in some regions, decreased or held steady elsewhere -- creating the world's first baseline against which to track future changes.
CO2 emissions in Los Angeles and the Washington DC/Baltimore regions fell roughly 33% in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study in Geophysical Research Letters led by NIST and NASA. But while the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact.
Scientists at the Marine Biological Laboratory (MBL) Ecosystems Center report that microplastics have been accumulating in salt marshes for decades, creating a historical record of human plastic waste.
