Edward Dolnick offers a history of the first dinosaur fossil discoveries in “Dinosaurs at the Dinner Party: How an Eccentric Group of Victorians Discovered Prehistoric Creatures and Accidentally Upended the World.” The Associated Press’ Andrew DeMillo writes that Dolnick’s brisk writing style transports readers to the 1800s and illustrates how much these discoveries changed science….
The Pyramid of Djoser, the oldest of Egypt’s iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to a study published August 5, 2024, in the open-access journal PLOS ONE by Xavier Landreau from CEA Paleotechnic Institute, France, and colleagues.

As the Olympic torch was carried toward Paris for the 2024 Summer Games, flames of another kind were causing concern for the city’s security chiefs. On the eve of the July 26 opening ceremony, a series of arson attacks disrupted travel into the capital along a high-speed rail network. As the Olympic torch was carried toward…
Full coherent control of wave transport and localization is a long-sought goal in wave physics research, which encompasses many different areas from solid-state to matter-wave physics and photonics. One among the most important and fascinating coherent transport effects is Bloch oscillation (BO), which refers to the periodic oscillatory motion of electrons in solids under a…

The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland’s ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape. The story of Greenland keeps getting greener—and scarier. A new study provides…
A study of horses—which share many important similarities with humans in their chromosomes and pregnancies—revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra set of chromosomes, a condition called triploidy. A study of horses—which share many important similarities with humans in their chromosomes…
A team of scientists and engineers at NASA and the U.S. Geological Survey (USGS) has collaborated to see if a small piloted drone, equipped with a specialized payload, could help create detailed maps of how fast water is flowing. Rivers supply fresh water to our communities and farms, provide homes for a variety of creatures,…
