Little is known concerning environmental contaminants in predators at the top of a food chain. A study published in Environmental Toxicology and Chemistry has demonstrated that new types of brominated flame retardants accumulate in the tissues of killer whales near Norway and are also passed on to nursing offspring.
Stunning Simulation of Stars Being Born Is Most Realistic Ever
A team including Northwestern University astrophysicists has developed the most realistic, highest-resolution 3D simulation of star formation to date.
Intensive Agriculture Could Drive Loss of Bees and Other Tropical Pollinators
Pollinators in the tropics are less likely to thrive in intensive croplands, finds a new study led by UCL researchers suggesting bees and butterflies are at risk of major losses.
Grazing Management of Salt Marshes Contributes to Coastal Defense
Combining natural salt marsh habitats with conventional dikes may provide a more sustainable and cost-effective alternative for fully engineered flood protection.
Oregon State Research Shows Why Some Pockets of Conifer Survive Repeated Forest Fires
Oregon State University researchers say “topographic templates” can help forest conservation managers develop strategies for protecting and restoring the most fire-resistant parts of vulnerable forests across a range of ecosystems.
