The Pecos River murals are a stunning collection of monumental, multicolored rock paintings in limestone rock shelters across southwest Texas and northern Mexico. They depict human-like figures that reach up to eight meters ...
An international team of geologists and paleontologists is pioneering a groundbreaking methodology to reliably determine the age of fossil-bearing rocks—by directly dating fossilized dinosaur eggshells.
Saliva is a bodily fluid most of us take for granted despite the significant roles it plays: aiding in digestion, maintaining strong teeth and defending against oral disease. However, the evolution of human saliva has been ...
We've feasted on them, built economies around them and in some places nearly erased them from our coasts. Today, 85% of the world's oyster reefs are gone. Many fisheries are collapsing, and those in Florida are no exception: ...
On January 14, 2004, the United States announced a new "Vision for Space Exploration," promising that humans would not only visit space but live there. Two decades later, NASA's Artemis program is preparing to return astronauts ...
In poultry houses where broiler chickens—birds bred and raised specifically for meat production—are grown, feed is delivered through long feed lines, which are mechanized systems that automatically deliver feed from storage ...
Scientists from the Canadian Museum of Nature have announced the discovery and description of an extinct rhinoceros from the Canadian High Arctic. The nearly complete fossil skeleton of the new species was recovered from ...
In vertebrates, calcium is stored in bones, and its release is tightly regulated. Now, using fruit flies as a model organism, researchers at University of Tsukuba have shown that even animals without bones possess specialized ...
When most people hear terms like poaching, wildlife trafficking or illegal wildlife trade, they probably think of threatened species such as elephants, rhinos, tigers or sharks. Geographically, wildlife crime may feel like ...
Researchers have developed a novel application of histological staining to screen for ancient proteins in situ—within the fossil's microstructure—advancing the field of paleoproteomics by addressing long-standing challenges ...
