A new study finds more deciduous trees like aspen are growing in after severe fires in the region, and that has some unexpected impacts.
Longleaf pines support one another through mycorrhizae – mutually beneficial relationships between certain fungi and the trees’ roots.
We may think of plants as passive life forms, but they can cooperate, share resources, send one another warnings, and distance themselves from their communities when survival depends on it.
Multiple queens ensure colonies have a steady output of workers.
The spread of tawny crazy ants may be driven, in part, by their need for calcium. The calcium-rich limestone bedrock of the lower U.S. Midwest may provide ideal conditions for populations to explode.
These compounds occur naturally in a number of healthy foods, including legumes and whole grains.
Anti-nutrients naturally occur in food and can block the amount of other nutrients available for your body to use. But their effects aren't all bad, which is why they're undergoing an image makeover.
Weathering of rocks like these basalt formations in Idaho triggers chemical processes that remove carbon dioxide from the air.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
These grasshoppers, like many insects around the world, are declining.
Insect populations are falling as what they eat becomes more like iceberg lettuce and less like kale.
Planting cover crops, like this red clover in Sussex County, Delaware, can help return carbon to farm fields.

Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
Mushrooms for many are just an addition to a slice of pizza, but the fungi are now gaining a reputation for their nutrients.
Mushrooms, long popular on pizza and in cooking, are getting more attention for their health benefits. Here are some reasons you might want to add them to your grocery list and not just your pizza.
Multiple reports have convincingly demonstrated that agroecology is the most promising pathway to sustainable food systems on all continents. But governments aren't doing enough to support it.
Biofortification – enhancing the micronutrient concentration of staple crops – offers a sustainable solution to hidden hunger.
Frozen, dried and freeze-dried fruit are certainly convenient. But are they as good for you as fresh fruit?
Dried and frozen fruit contain more sugar than their fresh equivalents. So, why do we think they're healthy?
Women (and their partners) can give their baby the best start in life by eating well even before they conceive.
