Dictionary

matter : material substance that occupies space, has mass, and is composed predominantly of atoms consisting of protons, neutrons, and electrons, that constitutes the observable universe, and that is interconvertible with energy — Merriam-Webster   See also OneLook

Thesaurus

Roget’s II (Thesaurus.com), Merriam-Webster Thesaurus, Visuwords

Encyclopedia

Matter is any substance that has mass and takes up space by having volume. All objects that we can touch are ultimately composed of atoms, which are made up of interacting particles, and in everyday as well as scientific usage, “matter” generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound. — Wikipedia

Innovation

The nature of the chemical bond is the problem at the heart of all chemistry. — Bryce Crawford

Science

Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. — Wikipedia

Recent News from Phys.org …

  • Cobalt honeycombs open a new path to quantum...
    on May 28, 2026 at 3:20 pm

    Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However, the metals used, such as ruthenium and iridium, are often rare and expensive, limiting the potential to build new technology.

    on May 28, 2026 at 3:00 pm

    Every summer, millions of people spray themselves with DEET to keep mosquitoes away. But new research suggests mosquitoes may be able to learn to associate the repellent with food—and even become attracted to it.

  • Platform fast-tracks microbial design for...
    on May 28, 2026 at 2:40 pm

    Scientists at the Department of Energy's Oak Ridge National Laboratory have developed a platform that engineers heat-loving microbes for industrial-scale manufacturing in a matter of weeks compared with previous approaches that can take months to years. This biotechnology tool strengthens American manufacturing capacity, supporting long-term energy security and global competitiveness.

  • Ripples in fire-ant collectives suggest motions...
    on May 28, 2026 at 2:00 pm

    Researchers in Spain have discovered that in collectives of moving fire ants, rippling "waves" of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.

  • Hyena clan rank metrics need to be trait specific...
    on May 28, 2026 at 1:20 pm

    Spotted hyenas live in hierarchically organized groups (clans). An individual's dominance over another determines priority access to resources such as food or mating partners, and thus reproductive success. However, the rank within the clan can be calculated using different metrics—and that matters. Using data from almost 500 hyenas collected over 28 years, scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) showed that different metrics best predict the animals' […]
