In a study published in Science Advances, researchers from Technical University of Denmark and Universidad Politécnica de Madrid demonstrate a new device called an acoustic rainbow emitter (ARE) that takes in broadband white-noise signals from a point source that radiates sound equally in all directions and scatters it up so that different sound frequencies or pitches are emitted. ...

All humans who have ever lived were once each an individual cell, which then divided countless times to produce a body made up of about 10 trillion cells. These cells have busy lives, executing all kinds of dynamic movement: contracting every time we flex a muscle, migrating toward the site of an injury, and rhythmically beating for decades on end. ...

Spanning thousands of kilometers, the experiment represents a significant step toward redefining the second and ultimately establishing a global optical time scale. ... Read full Story
Sharing disappointing results with a world of researchers working to find what they hope will be the "discovery of the century" isn't an easy task, but that is what Penn State theoretical physicist Zoltan Fodor and his international research group did five years ago with their extensive calculation of the strength of the magnetic field around the muon—a sub-atomic particle similar to, but heavier than, an electron. At the time, their finding was the first to close the gap between theory and experimental measurements, bringing it in line with the Standard Model, the well-tested physics theory that has guided particle physics for decades. ...

Merriam-Webster's Word of the Day for June 15, 2025 is:
progeny \PRAH-juh-nee\ noun
Progeny refers to the child or descendant of a particular parent or family. Progeny can also refer to the offspring of an animal or plant, or broadly to something that is the product of something else. The plural of progeny is progeny.

“‘I am (We are) our ancestors’ wildest dreams.’ The phrase originated from New Orleans visual artist, activist, and filmmaker Brandan Odums, and was popularized by influential Black figures like Ava Duvernay, who used the phrase in tribute to the ancestors of First Lady Michelle Obama. Melvinia Shields, who was born a slave in 1844, would be survived by five generations of progeny, ultimately leading to her great-great-great granddaughter—Michelle Obama ...” — Christopher J. Schell, “Hope for the Wild in Afrofuturism,” 2024

Progeny is the progeny of the Latin verb prōgignere, meaning “to beget.” That Latin word is itself an offspring of the prefix prō-, meaning “forth,” and gignere, which can mean “to beget” or “to bring forth.” Gignere has produced a large family of English descendants, including benign, engine, genius, germ, indigenous, and genuine. Gignere even paired up with prō- again to produce a close relative of progeny: the noun progenitor can mean “an ancestor in the direct line,” “a biologically ancestral form,” or “a precursor or originator.”
