A debate continues among scientists over whether tree composition in forests in eastern North America historically have been influenced more by climate or by cultural burning, which is the intentional and controlled use of fire by Indigenous people to man

Researchers led by Professor Erik van Nimwegen at the Biozentrum, University of Basel, have discovered a new mechanism in bacteria that controls their response to prevailing environmental conditions. They derived their theory from a simple yet interesting

When a species reproduces, typically, each parent passes on one of their two versions (alleles) of a given gene to their offspring. But not all alleles play fair in their quest to be passed onto future generations.

A peculiar spiny fossil, once thought to represent one of the earliest mollusks, has now been conclusively reclassified by scientists from Durham University and Yunnan University as something entirely different—a distant relative of sponge-like creatures

What lives off the Northwest coasts of Spain and shrinks to one-fifth of its size when alarmed? Enter the accordion worm. This recently identified marine ribbon worm, colored brown to dark green, measures 110–250 mm long and 3–4 mm wide in its unbothered

Accessing carbon and nature payments from governments and other organizations often requires robust measurements to quantify restoration's positive impact, but these can be beyond the capacity of community organizations.

Our attraction to sugar has grown to an unhealthy level. The average person in the United States now consumes more than 100 pounds of the sweet stuff every year, up from 18 pounds in 1800.

Bacterial resistance negates the effect of antibiotics in the treatment of infection. Using mouse models, researchers now show that if antibiotics are administered with an enzyme called endolysin, the combined effect protects against infection by resistan

Staphylococcus borealis has been found to be resistant to several different types of antibiotics, posing a potentially significant problem for the elderly.

Tyrannosaurus rex evolved in North America, but its direct ancestor came from Asia, crossing a land bridge connecting the continents more than 70 million years ago, according to a new study led by UCL researchers.

Most of India's snow leopard population live in a remote region in the north of the country, where they co-exist alongside rural communities, according to a study published in PLOS One by Pankaj Raina at Union Territory of Ladakh's Department of Wildlif

Parental care might help invasive brown widow spiders spread. Valeria Arabesky and colleagues at Ben-Gurion University of the Negev found that invasive brown widow spiders effectively defend their egg sacs against wasp parasites. The spiders use multiple
