Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.

Phys.org / Astronomers capture an exceptional gamma-ray flare from a blazar

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection ...

Phys.org / Tiny lead fragments in hunted meat exceed safe levels, study reveals

This fall, when Adam Leontowich headed to southeast Saskatchewan to hunt whitetailed deer and ruffed grouse, he once again opted for lead-free ammunition—cartridges with copper bullets for his .308 rifle and shells with ...

Phys.org / Studies show how the giant statues on Rapa Nui were made and moved—and what caused the island's deforestation

Rapa Nui, also known as Easter Island, is often portrayed in popular culture as an enigma. The rationale is clear: The tiny, remote island in the Pacific features nearly 1,000 enormous statues—the moai. The magnitude and ...
