A dense quark liquid is distinct from a dense nucleon liquid
Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quar.....»»
The microbiology of honey: A sweet symphony of life
Honey, a complex substance made by a variety of species of bees, is often celebrated for its sweetness and health benefits. In fact, humans have been using honey, sometimes called liquid gold, for generations to soothe cold symptoms and promote wound.....»»
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the.....»»
Most precise measurement of electrically neutral beauty meson lifetime achieved
The ATLAS collaboration at the Large Hadron Collider (LHC) has released a new high-precision measurement of the lifetime of the electrically neutral beauty (B0) meson—a hadron composed of a bottom antiquark and a down quark......»»
Molecular "pinball": Superfast collisions predict supercritical fluid properties
Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ideal for a wide variety of chemical, pharmaceutical a.....»»
Survey of 26,000 dead stars confirms key details of extreme stellar behavior
A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when they have the same mass......»»
Ferns" ability to evolve "backward" offers insights into the meandering path of evolution
Imagine a photograph of your great-grandparents, grandparents and parents side by side. You'd see a resemblance, but each generation would look distinct from its predecessors. This is the process of evolution in its simplest form: descent with modifi.....»»
New study says we"re unlikely to find liquid water on Mars anytime soon
More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to bu.....»»
Do the fastest-spinning pulsars contain quark matter?
Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons are squeezed together with protons so that the co.....»»
Physicists uncover strong light-matter interactions in quantum spin liquids
Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, they remain in a constantly.....»»
Tuning skyrmion helicity for racetrack memory and quantum computing applications
Three distinct topological degrees of freedom are used to define all topological spin textures based on out-of-plane and in-plane spin configurations: the topological charge, representing the number of times the magnetization vector m wraps around th.....»»
Shape-changing polymer resembles animal movements with temperature shifts
A team of scientists has created a new shape-changing polymer that could transform how future soft materials are constructed. Made using a material called a liquid crystalline elastomer (LCE), a soft rubber-like material that can be stimulated by ext.....»»
Getting a grip on quark mixing: Physicists introduce framework to determine amount of mixing between up and down quarks
The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not very well known, though—and the theoretical values.....»»
Male African elephants develop distinct personality traits as they age
Male African elephants have distinct personality traits, but also adapt their behavior to suit the social context, according to a study published December 4, 2024, in the open-access journal PLOS ONE by Caitlin O'Connell-Rodwell at Stanford Universit.....»»
Liquid water molecules are inherently asymmetric: New insight into the bonds between water molecules
Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e. properties of liquids that are rarely observed for.....»»
Genetic evidence points to distinct Viking settlers of the Faroe Islands and Iceland
Geneticists have studied the distribution of Y-chromosome haplogroups on the Faroe Islands, known to have been colonized by Vikings around the year 900 CE, and compared these to distributions of haplogroups in today's Scandinavia......»»
Accessing the lesser known nucleon: New neutron measurement can help physicists learn about nucleon structure and spin
Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments......»»
Exploring new liquid organic hydrogen carrier materials for a safer, more transportable energy source
To reduce CO2 emissions, the energy transition from a carbon-based energy system to a more sustainable system based on hydrogen energy is urgently needed. However, the nature of hydrogen (such as low volumetric density, flammability, and embrittlemen.....»»
Researchers develop pioneering monitoring technique to help build mangrove resilience
Mangroves are remarkable ecosystems home to amazing biodiversity, dense vegetation, and conditions that capture large quantities of carbon. Since they occur in warm, tropical, and subtropical coastal regions, they also take the brunt of the impact fr.....»»

Evaluating GRC tools
According to Gartner, the broad range of pricing for government, risk, and compliance (GRC) tools requires enterprise risk management (ERM) leaders to be well-versed in distinct pricing tiers of GRC solutions. In this Help Net Security video, Joel Ba.....»»
