‘Lying mirror’ uses structured surfaces to conceal optical information

Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a “lying mirror” that hides information carried by an input image and transforms it into a misleading, ordinary-looking pattern at the output. The […]

Astronomers find a new object from the early universe using Webb data

Since it became operational in 2022, the James Webb Space Telescope (JWST) has released some truly breathtaking views of the cosmos. These images highlight how advancements since the days of the venerable Hubble Space Telescope are now providing the deepest and clearest views of the cosmos to date. The work is published on the arXiv […]

Tiny particles defy action-reaction symmetry to stay in motion

From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active matter because their components continuously use energy to generate motion, either individually or through interactions with their environment.

Cosmic filaments help set first limits on dark matter’s decay into gravitons

Composing some 85% of the universe’s total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York University has proposed a new way to hunt for the elusive substance. Their approach involves searching for the […]

Rare Mars meteorite preserves 1.27-billion-year-old clues to planet’s deep interior

Boston College scientists have determined that a newly discovered meteorite from Mars is 1.27 billion years old and derived from a previously unsampled, pristine source on the Red Planet. The study is published in the journal Geochimica et Cosmochimica Acta.

The asteroid that may be three worlds

What shape is an asteroid? For (44) Nysa, the honest answer until now has been that nobody knew. It is one of the brightest and largest E-type asteroids in the main belt, a class with a surface rich in enstatite, and its oddness has made it a favorite target for well over a hundred years. […]

‘Flying focus’ laser overcomes key limitation in plasma-based particle accelerators

In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible by a specially engineered laser pulse called a flying focus, which counteracts a longstanding limitation known as “dephasing.”

Reduced gravity pushes people toward simpler movement patterns, experiments suggest

From reaching for a cup of coffee to tying your shoelaces, gravity shapes nearly all human movement. So how do our bodies react when that familiar force begins to change? Texas A&M University researchers are exploring the answer through a multiphase project supported by NASA.
