Plowing, or tilling, is an age-old agricultural practice that readies the soil for planting by turning over the top layer to expose fresh earth. The method—intended to improve water and nutrient circulation—remains popular today, but concerns about soil degradation have
New research led by a University of Wyoming archaeologist near an ancient encampment in South America challenges a relatively new but widely accepted theory that the people who made and used Clovis points in North America were not the first inhabitants of the Americas south of
Human genes are written in long strings of three-letter units composed of four different nucleotides. These units—or codons—specify one of many amino acids, the building blocks of proteins. Multiple codons can encode the same amino acid, which seems to point to some redundancy
The bright colors of butterfly wings, the sweet aromas of flowers, and the euphonious melodies of songbirds all evolved as signals that help individuals propagate, yet humans also find these very same signals pleasing to their own senses.
The history of Earth is written on the great tablets of tectonic plates. The motions of plates shaped land masses, formed oceans, and created the varied climates and habitats that set the stage for evolution and the diversity of life. But this grand drama begins with a deep
Swedish old-growth forests store 83% more carbon than managed forests, according to a new study from Lund University. The difference is substantially larger than previous estimates and is mainly due to large carbon stocks in the soil.
Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its start back by 140 million years.
