A team of researchers at the University of Liverpool has tested the assumption that hafted tools (those with handles) provided early humans with enough benefit to warrant their construction and use. In their paper published ...
To understand how life emerged, scientists investigate the chemistry of carbon and water. In the case of water, they track the various forms, or isotopes, of its constituent hydrogen and oxygen atoms over the history of the ...
