Seattle metro residents near Amazon delivery stations face more pollution but order fewer packages
Seattle metro residents near Amazon delivery stations face more pollution but order fewer packages
While it is common to see Amazon Prime vans circling the city of Seattle year-round, there might be even more deliveries than usual right now, thanks to the Black Friday and Cyber Monday deals that rang in the holiday season. Researchers at the University of Washington were curious how the delivery of e-commerce products affects pollution levels across the Seattle metropolitan area, which includes Tacoma, Seattle, Bellevue and Everett.

How forests smell - a risk for the climate?
Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers from Leipzig University, the Leibniz Institute for Tropospheric Research (TROPOS) and the German Centre for Integrative Biodiversity Research (iDiv) carried out a study to investigate how biodiversity influences the emission of these substances.

Satellite-based method measures carbon in peat bogs
The technique could enable restoration efforts and doesn't require labor-intensive onsite sampling. Peat bogs in the tropics store vast amounts of carbon, but logging, plantations, road building, and other activities have destroyed large swaths of these ecosystems in places like Indonesia and Malaysia.

Heavy metals in the rivers of Greenland
Heavy metals in the rivers of Greenland
Field studies by Eawag researcher David Janssen in southern Greenland show that the heavy metals in the rivers are largely of natural origin, and that the influence of mining and agriculture is negligible, at least during the period observed. The rivers in Greenland can transport unusually high concentrations of heavy metals, including copper, zinc, gold, silver, platinum, lead and mercury.

Finding more sustainable ways to use plastics in agriculture
International scientists including UdeM professor Kevin Wilkinson address the worrisome problem of millions of tonnes of plastic being used on farms around the world. Every year, according to the United Nations Food and Agriculture Organization, some 12.5 million tonnes of plastic are used in agricultural production worldwide.

What’s for dinner? Paleontologist finds out through remarkable specimen
1st-ever prey found inside fossilized juvenile tyrannosaur leads to deeper understanding about feeding habits of these iconic predators The difference between a juvenile and adult tyrannosaur is massive - both figuratively and literally. While adults weighed around 3,000 kilograms, the weight of a pick-up truck, juveniles were much leaner.

Beluga whales’ calls may get drowned out by shipping noise in Alaska’s Cook Inlet
Beluga whales are highly social and vocal marine mammals. They use acoustics to navigate, find prey, avoid predators and maintain group cohesion. For Alaska's critically endangered Cook Inlet beluga population, these crucial communications may compete with a cacophony of noise from human activities. New research from the University of Washington, the National Oceanic and Atmospheric Administration's Alaska Fisheries Science Center and the Alaska Department of Fish and Game is the first to document the complex vocal repertoire of the Cook Inlet beluga whale population.

Dreissenid mussels: the resilience and success of an invasive species
Scientists shed light on unique fibre structure, evolutionary history and combating invasive species Zebra and quagga mussels, which belong to the Dreissenid family, are freshwater invasive species widespread throughout western Europe and North America. They present a significant danger to native ecosystems by competing for resources.

Battery recycling: China is in first place
China covers its demand for lithium, cobalt and nickel for batteries by recycling, ahead of Europe and the USA. With the increasing production of batteries for electric vehicles, the demand for the necessary raw materials is also rising. In view of the supply risks, environmental problems and precarious working conditions associated with the extraction and transportation of these raw materials, the recycling of battery materials has become an important topic in science, politics and industry.

Suburban backyard home to more than 1,000 species
Suburban backyard home to more than 1,000 species
A challenge among three housemates to identify species around their inner-Brisbane home has resulted in an academic research paper, showcasing the rich biodiversity in urban landscapes. UQ mathematician Dr Matt Holden , ecologist Dr Andrew Rogers and taxonomist Dr Russell Yong took a census of their Annerley share house and its backyard during the COVID-19 lockdowns in 2020, and discovered 1,150 unique species of animals, plants and fungi over a 12-month period.

How researchers designed Australia’s first mobile cooling hub
Socially disadvantaged people are especially exposed to extreme heat. Dr Timothy English and co-authors explore a pilot project opening in Sydney will use the best available evidence to keep vulnerable people cool on the hottest of days. Heatwaves are a major public health hazard. Socially disadvantaged people are especially exposed to extreme heat and other impacts of climate change.

Methane emissions from canals underestimated
Researchers have so far underestimated methane emissions from canals in five major Dutch cities. That is the conclusion of microbiologist Koen Pelsma, who will defend his PhD thesis on this topic at Radboud University on 13 December. In calculations of methane emissions from water, far too little is known about emissions from urban waters such as canals, says researcher Koen Pelsma.

Deciphering nature’s climate shield: Plant diversity stabilises soil temperature
A new study has revealed a natural solution to mitigate the effects of climate change, such as extreme weather events. Researchers from Leipzig University, the Friedrich Schiller University Jena, the German Centre for Integrative Biodiversity Research Halle-Jena-Leipzig (iDiv) and other research institutions have discovered that high plant diversity acts as a buffer against fluctuations in soil temperature.

Urbanization increases seasonal differences in plant-pollinator networks
Research team led by Göttingen University investigates importance of season and environment in tropical megacity Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities.
