The study used GPS location data from 65 bird tracking studies to understand where they fly more frequently at danger height — defined as 10-60 metres above ground for power lines and 15-135 metres for wind turbines. This allowed the team to identify the areas where these birds would be more sensitive to onshore wind …

“In this study, we provide evidence that public drinking water quality has been compromised by shale gas development,” said Elaine Hill, Ph.D., an associate professor with the University of Rochester Departments of Public Health Sciences, Economics and Obstetrics & Gynecology. “Our findings indicate that drilling near an infant’s public water source yields poorer birth outcomes …

It has become imperative then that we develop efficient and cost-efficient ways to decontaminate water. And that is exactly what a team of scientists led by László Forró at EPFL have accomplished, with a new water purification filter that combines titanium dioxide (TiO2) nanowires and carbon nanotubes powered by nothing but sunlight. The scientists first …

Styrofoam egg cartons, hard plastic compact disc cases, red drinking cups and many other common products are composed of polystyrene, which makes up a third of landfill waste worldwide. A team led by Erin Stache, assistant professor of chemistry and chemical biology at Cornell, found the reaction can even take place in a sunny window. …

There are various sources of indoor air pollution. Outdoor air pollutants enters the room through the doors and windows of the living room and the gaps in the building. It increases the concentration of the corresponding indoor pollutants. Some buildings contain certain volatile harmful substances, such as radioactive radon in building stones and floor tiles. …

The lowland rainforests of the Amazon River basin harbor more diversity than any other terrestrial ecosystem on the planet. It is also a globally important biome containing about 18 percent of all trees on Earth and carrying more fresh water than the next seven largest river basins combined. Researchers have long wondered and hotly debate …

Published today in Science Advances, the study reveals rapid degradation in air quality and increases in urban exposure to air pollutants hazardous to health. Across all the cities, the authors found significant annual increases in pollutants directly hazardous to health of up to 14% for nitrogen dioxide (NO2) and up to 8% for fine particles …

The findings have important applications for atmospheric science and for climate change modeling. “The tropical Amazon rainforest constitutes the lungs of the Earth, and this study connects natural processes in the forest to aerosols, clouds, and the Earth’s radiative balance in ways that have not been previously recognized,” said Manish Shrivastava, Earth scientist at PNNL …

Climate scientists count the Atlantic Meridional Overturning Circulation (or AMOC) among the biggest tipping points on the way to a planetary climate disaster. The Atlantic Ocean current acts like a conveyor belt carrying warm tropical surface water north and cooler, heavier deeper water south. “We’ve been taught to picture it like a conveyor belt — …

A healthy life comes from fresh air, and indoor air has a great impact on the health of the body. According to statistics, urban residents spend about 70%-90% of their time in various indoor environments every day. But according to the World Health Organization (WHO) report, nearly half of the world’s people are exposed to …
