Scientists have discovered that birds know to avoid the plants where toxic animals dwell.
Recycled concrete and CO2 from the air are made into a new building material
A new kind of concrete could reduce emissions from the construction industry. Calcium carbonate concrete is made from waste concrete and carbon dioxide from the air or industrial exhaust gases. It shows promise as a future construction material, especially in places where natural resources are limited.
Nature-based activities can improve mood and reduce anxiety
Outdoor nature-based activities are effective for improving mental health in adults, including those with pre-existing mental health problems, a new study has found.

Extinct ground sloth likely ate meat with its veggies
A new study suggests that Mylodon -- a ground sloth that lived in South America until about 10,000 to 12,000 years ago -- was not a strict vegetarian like all of its living relatives. Based on a chemical analysis of amino acids preserved in sloth hair, the researchers uncovered evidence...
Abundance of microscopic paint flakes in the North Atlantic
Flakes of paint could be one of the most abundant type of microplastic particles in the ocean, new research has suggested. Through a range of surveys conducted across the North Atlantic Ocean, scientists estimated that each cubic meter of seawater contained an average of 0.01 paint flakes.
Genetic analysis reveals differences in mate choice between wild and hatchery coho salmon
A new study of the genetic profiles of wild and hatchery coho salmon demonstrates important distinctions in how the two types of fish form mating pairs.

A new study looks at the causal relationship between outdoor air pollution levels on nationwide university entry examination day and students' cognitive performance in Brazil.
Crayfish and carp among the invasive species pushing lakes towards ecosystem collapse
Certain invasive, non-native species can disrupt lakes to the point of rapid ecosystem collapse, contaminating water for drinking, aquaculture and recreation, a new study has found.
Protecting the ozone layer is delivering vast health benefits
An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research.
