Archaeologists have analyzed chemical residues from ceramic vases at the city of Cotzumalhuapa, Guatemala, revealing physical evidence of tobacco use in Mesoamerica, likely for ritual and therapeutic purposes.
Scientists from the University of Rochester have developed new electrochemical approaches to clean up pollution from "forever chemicals" found in clothing, food packaging, firefighting foams, and a wide array of other products. ...
Scientists have confirmed the presence of a whale off New England that went extinct in the Atlantic Ocean two centuries ago—an exciting discovery, but one they said that illustrates the impact of climate change on sea life.
Roughly 4 billion years ago, Earth was developing conditions suitable for life. Origin-of-life scientists often wonder if the type of chemistry found on the early Earth was similar to what life requires today. They know that ...
To understand the food production resources necessary to help feed a growing global population, accurate and up-to-date data, such as crop, livestock, aquaculture and fisheries statistics, are crucial for the implementation ...
In the predawn hours of Sept. 5, 2021, engineers achieved a major milestone in the labs of MIT's Plasma Science and Fusion Center (PSFC), when a new type of magnet, made from high-temperature superconducting material, achieved ...
Scientists have solved the mysterious absence of star-shaped dunes from Earth's geological history for the first time, dating one back thousands of years.
Dark matter comprises around 85% of all the matter in the universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection difficult. Its existence is inferred ...
Put the word "evolution" into Google images and the results are largely variations on one theme: Ralph Zallinger's illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming ...
Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team, led by researchers ...
