Materials can remember a sequence of events in an unexpected way

Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team led by Penn State physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations.

The mysterious descriptions of Noah’s Ark

Having a very unusual design, Noah’s ark is usually depicted in ancient illustrations as an ancient ship with a round hull, with a detailed prow and stern, having a keel running through the entire length of the ship. The top part of the ship has an unusual cabin that covers the entire length of […]

Dust from asteroid Bennu suggests solar system’s potential for life was widespread

It took two years for NASA’s OSIRIS-REx space probe to return from asteroid Bennu before dropping off a small capsule as it flew past Earth, which was then recovered in the desert of the U.S. state of Utah on September 24, 2023. Its contents: 122 grams of dust and rock from asteroid Bennu.

Is it time to start classifying exoplanetary systems?

When an exoplanet is discovered, scientists are quick to describe it and explain its properties. Now, we know of thousands of them, many of which are members of a planetary system, like the well-known TRAPPIST-1 family of planets.

Asteroid Bennu samples found to contain five nitrogenous bases crucial to supporting life

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building blocks of life to Earth billions of years ago. Although meteorites on Earth come from asteroids, the combination of exposure to moisture in the atmosphere and to an uncontrolled biosphere means that interpreting the data from them […]

The hidden power of the smallest microquasars: Study finds evidence of particle acceleration

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that create fascinating shooting stars in the night sky, it’s the smallest particles that help scientists to understand the nature of the universe.

Hubble reveals unusual globular clusters in ultra-diffuse galaxy FCC 224

Using the Hubble Space Telescope (HST), astronomers from the University of California Santa Cruz (UCSC) and elsewhere have observed an ultra-diffuse galaxy known as FCC 224. Results of the observational campaign, published Jan. 18 on the arXiv pre-print server, provide important insights into the properties of this galaxy and its globular cluster system.

Quantum theory and thermodynamics: No contradiction with new entropy definition, study says

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more precisely: that entropy must increase in every closed system.

Plasma technique doubles etch rate for 3D NAND flash memory

To store ever more data in electronic devices of the same size, the manufacturing processes for these devices need to be studied in greater detail. By investigating new approaches to making digital memory at the atomic scale, researchers engaged in a public-private partnership are aiming to address the endless demand for denser data storage.
