Air toxic emissions from on-road mobile sources are significant contributors to the degradation of air quality in urban and dense population centers. Research led by the United States Environmental Protection Agency (EPA) identified more than 1162 hazardous air pollutants (HAPs) in the exhaust and evaporative emissions from on-road mobile sources.
Toothed Whales Catch Food in the Deep Using Vocal Fry
Dolphins and other toothed whales are large brained top predators that captivate our imagination; they are extremely social, they cooperate, and can hunt prey down to 2km deep in complete darkness with echolocation.
Illuminating the Science of Black Holes and Gamma-Ray Bursts Using High-Power Lasers
High-power lasers now create record-high numbers of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts.
Scientists Use Satellites To Track Earth ‘Greening’ Amid Climate Change
North Carolina State University researchers used satellite imagery and field sensors to estimate worldwide changes in plant leaf growth due to global warming.
Additive to Make Slurry More Climate-Friendly
Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate.
Coastal Water Pollution Transfers to the Air in Sea Spray Aerosol and Reaches People on Land
New research led by Scripps Institution of Oceanography at UC San Diego has confirmed that coastal water pollution transfers to the atmosphere in sea spray aerosol, which can reach people beyond just beachgoers, surfers, and swimmers.
Keto vs Vegan: Study of Popular Diets Finds Over Fourfold Difference in Carbon Footprints
A new study from Tulane University which compared popular diets on both nutritional quality and environmental impact found that the keto and paleo diets, as eaten by American adults, scored among the lowest on overall nutrition quality and were among the highest on carbon emissions.
Robot Provides Unprecedented Views Below Antarctic Ice Shelf
High in a narrow, seawater-filled crevasse in the base of Antarctica’s largest ice shelf, cameras on the remotely operated Icefin underwater vehicle relayed a sudden change in scenery.
Reassessment of Storegga Event: Second Major Landslide Recognized
Submarine landslides have a large tsunami potential and occurred on the central Norwegian shelf more frequently in the past than previously thought.
Wastewater Sector Emits Nearly Twice as Much Methane as Previously Thought
Municipal wastewater treatment plants emit nearly double the amount of methane into the atmosphere than scientists previously believed, according to new research from Princeton University.
