In the Cretaceous period, Earth was plagued by widespread volcanic activity, oceanic oxygen depletion events, and mass extinctions. Fossils from that era remain and continue to give scientists clues as to what the climate ...

Johns Hopkins researchers have discovered new materials and a new process that could advance the ever-escalating quest to make smaller, faster and affordable microchips used across modern electronics—in everything from ...

In the Bronze Age, the so-called Nuraghe culture flourished in Sardinia. A culture that is known for tower-like stone constructions, nuraghers, and for the small bronze figures, bronzetti, which often depict warriors, gods ...

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the very heart of matter, giving rise to everything we see around us as it anchors the nuclei of atoms. ...

Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have previously been unable to explain.

In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant ...

Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent ...

Paleontologists at the University of Bristol have officially identified a new species of dinosaur from Triassic fossil beds in South Wales, near Penarth—more than 125 years after the specimen was initially reported.

A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King's College London reveal. The paper is published in the journal Physical Review X.

Researchers at Kaunas University of Technology (KTU), Lithuania, have developed new organic compounds that act as highly sensitive oxygen sensors. These sensors can accurately detect even the slightest amounts of oxygen in ...

Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), a sediment core from the Southeast Pacific was examined that reflects the last 8 million years of Earth's history.

Imagine tugging on a Chinese finger trap. The harder you pull, the tighter it grips. This counterintuitive behavior also exists in biology. Certain protein complexes can form catch-bonds, tightening their grip when force ...
