Experiment indicates new type of mesic nuclei that could reveal how matter acquires mass

Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter acquires its mass from interaction with a physical vacuum—it is not an empty space, but contains a complex structure. Investigating the system of a meson—a composite particle made of a quark, an […]

Parabolic flight test shows lasers can propel graphene aerogels in microgravity

Lasers could one day steer solar sails and adjust a satellite’s position in outer space, thanks to graphene. An experiment on a gravity rollercoaster ride showed how this innovative material has the potential to revolutionize propulsion beyond Earth.

Metamaterial chains learn new shapes by sharing data hinge to hinge

In a new Nature Physics publication, University of Amsterdam researchers introduce human-made materials that spring to life. These ‘metamaterials’ don’t just learn to change shape, but can autonomously adapt their shape-changing strategy, perform reflex actions and move around like living systems do.

First close pair of supermassive black holes detected

Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to accumulate their enormous masses, they must merge with each other. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn has found direct evidence of […]

How Jupiter cultivated more large moons than Saturn

The two largest planets in our solar system, Jupiter and Saturn, also have the largest satellite systems, or the most moons. At present, Jupiter’s reported moon count stands at more than 100 moons, and along with its many rings, Saturn has more than 280 reported moons. Not all these moons are equal, however. Jupiter’s moon […]

New Artemis II ‘Earthset’ shot revisits Apollo 8’s iconic ‘Earthrise,’ 57 years on

A layered approach sharpens brain signals in optical imaging

Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near-infrared light into the head, and detectors measure the light that scatters back. Because this light must pass through the scalp and skull before reaching […]
