Better understanding the physics of our universe      (via sciencedaily.com)     Original source 

Researchers from around the world have sought to answer important questions about the most basic laws of physics that govern our universe. Their experiment, the Majorana Demonstrator, has helped to push the horizons on research concerning one of the fundamental building blocks of the universe: neutrinos.

Temperature is stronger than light and flow as driver of oxygen in US rivers      (via sciencedaily.com)     Original source 

The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers used a deep learning model to analyze data from hundreds of rivers across the United States.

How to see the invisible: Using the dark matter distribution to test our cosmological model      (via sciencedaily.com)     Original source 

Astrophysicists have measured a value for the 'clumpiness' of the universe's dark matter (known to cosmologists as 'S8') of 0.776, which does not align with the value derived from the Cosmic Microwave Background, which dates back to the universe's origins. This has intriguing implications for the standard cosmological model.

Random matrix theory approaches the mystery of the neutrino mass      (via sciencedaily.com)     Original source 

Scientists analyzed each element of the neutrino mass matrix belonging to leptons and showed theoretically that the intergenerational mixing of lepton flavors is large. Furthermore, by using the mathematics of random matrix theory, the research team was able to demonstrate, as much as is possible at this stage, why the calculation of the squared difference of the neutrino masses are in close agreement with the experimental results in the case of the seesaw model with the random Dirac and Majorana matrices. The results of this research are expected to contribute to the further development of particle theory research, which largely remains a mystery.

Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease      (via sciencedaily.com)     Original source 

Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.

Coral skeletons influence reef recovery after bleaching      (via sciencedaily.com)     Original source 

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

DMI allows magnon-magnon coupling in hybrid perovskites      (via sciencedaily.com)     Original source 

An international group of researchers has created a mixed magnon state in an organic hybrid perovskite material by utilizing the Dzyaloshinskii--Moriya-Interaction (DMI). The resulting material has potential for processing and storing quantum computing information.

Absolute zero in the quantum computer      (via sciencedaily.com)     Original source 

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.

Red tide warning system      (via sciencedaily.com)     Original source 

Current methods to monitor red tide are limited. Using AUTOHOLO, a new autonomous, submersible, 3D holographic microscope and imaging system, a study is the first to characterize red tide in the field and breaks new ground for monitoring harmful algal blooms.

Ocean warming intensifies viral outbreaks within corals      (via sciencedaily.com)     Original source 

A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.

Scientists discover hidden crab diversity among coral reefs      (via sciencedaily.com) 

The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.

Charming experiment finds gluon mass in the proton      (via sciencedaily.com)     Original source 

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the strong force as it glues together the proton's building block quarks.

Earth prefers to serve life in XXS and XXL sizes      (via sciencedaily.com) 

Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.

Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials      (via sciencedaily.com)     Original source 

Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.
