Just milliseconds after the universe’s Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes. Did primordial black holes help or hinder formation of the universe’s first stars, eventually born about 100 million years later?
Researchers have developed a technique to 3D-print materials with customizable mechanical properties that can also sense how they are moving and interacting with their environment. Their method only requires one printing material and a single run on a 3D printer.
Researchers discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth’s mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.
Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs — like Brontosaurus and Diplodocus — supported their gigantic bodies on land.
A study analyzes the effect of global rising temperatures and climate change on Gross Domestic Product, finding nearly a quarter of the countries studied are sensitive to such impacts.
