What The Study Did: This study describes four patients who presented with acute myocarditis after mRNA COVID-19 vaccination.

Scientists from China present the fastest real-time quantum random number generators to date to make the devices quicker and more portable. The device combines a state-of-the-art photonic integrated chip with optimized real-time postprocessing for extracting randomness from quantum entropy source of vacuum states.

In Physics of Fluids, investigators from the University of Florida and Lebanese American University carried out detailed computer simulations to test a mathematical theory they developed previously. They found nearly identical exhalations could spread in different directions when miniscule initial variations are substantially amplified by turbulence. This is the so-called butterfly effect.

Ten million years before the well-known asteroid impact that marked the end of the Mesozoic Era, dinosaurs were already in decline. That is the conclusion of the Franco-Anglo-Canadian team led by CNRS researcher Fabien Condamine from the Institute of Evolutionary Science of Montpellier, which studied evolutionary trends during the Cretaceous for six major families of dinosaurs, including those of the tyrannosaurs, triceratops, and hadrosaurs.

The oldest strain of Yersinia pestis -- the bacteria behind the plague that caused the Black Death, which may have killed as much as half of Europe's population in the 1300s -- has been found in the remains of a 5,000-year-old hunter-gatherer. A genetic analysis publishing June 29 in the journal Cell Reports reveals that this ancient strain was likely less contagious and not as deadly as its medieval version.

Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. In Physics of Fluids, researchers show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type.

For wind farms, it is important to control upstream turbines in an efficient manner so downstream turbines are not adversely affected by upstream wake effects. In the Journal of Renewable and Sustainable Energy, researchers show that by designing controllers based on viewing the wind farm system as a coupled network, it is possible to extract power more efficiently.

The death of the dinosaurs 66 million years ago was caused by the impact of a huge asteroid on the Earth. However, paleontologists have continued to debate whether they were already in decline or not before the impact.In a new study, published today in the journal Nature Communications, an international team of scientists, which includes the University of Bristol, show that they were already in decline for as much as ten million years before the final death blow.

In Physics of Fluids, researchers have developed a method to turn biodegradable plastic knives, spoons, and forks into a foam that can be used as insulation in walls or in flotation devices. The investigators placed the cutlery into a chamber filled with carbon dioxide. As pressure increased, the gas dissolved into the plastic. When they suddenly released the pressure in the chamber, the carbon dioxide expanded within the plastic, creating foaming.

Researchers working on the Faraday Institution project on the recycling of lithium-ion batteries (ReLiB) at the Universities of Leicester and Birmingham have solved a critical challenge in the recovery of materials used in electric vehicle batteries at the end of their life, enabling their re-use in the manufacture of new batteries.

Australian theoretical physics study just out has identified a 'smoking gun' in long search for the topological magnetic monopole referred to as the Berry curvature. This breakthrough in search for topological effects in non-equilibrium systems opens paths towards low-energy topological electronics viable for large-scale, room-temperature operation.

In a new study, researchers from the Gwangju Institute of Science and Technology in Korea have investigated the transformation dynamics induced by an electric field in mixed-phase lanthanum-doped bismuth ferrite (BLFO) epitaxial thin films. They observed a connection between the presence of S/Stilt phases in BLFO film and their high piezoelectricity. These findings can help us design faster and more efficient piezoelectric materials.

The groundbreaking technology may revolutionize the treatment of cancer and a wide range of diseases and medical conditions.

Researchers took a close look at bobtail and bottletail squids to establish their evolutionary relationships and the timing of the divergence of different species.

A layer of hierarchically three-dimensional porous graphene greatly suppresses a problem holding back the development of lithium-sulfur batteries.

Researchers have identified a new treatment candidate that appears to not only halt neurodegenerative symptoms in mouse models of dementia and Alzheimer's disease, but also reverse the effects of the disorders.

Due to plasmon resonance, the electric field near a metal nanoparticle can be enhanced by tens and hundreds of times. This means that such nanostructures function as optical nanoantennas that enhance the light-matter interaction.

Researchers from University of Tsukuba have developed an artificial intelligence system that identified signs of mental distress in workers using only sociodemographic, lifestyle, and sleep data. The predictions made by the system were comparable to those made by a team of psychiatrists. Such systems may be helpful for identifying signs of depression in individuals who may be hesitant to report subjective feelings of distress as a result of mental health stigma.

Prolonged exposure to antibiotics leads to the gain of bacteria's ability to defeat the drugs designed to fight them. Thus, if such antibiotic-resistant bacteria cause the infection, the only chance to use a specialized virus called phage infecting specific bacteria species. It is a powerful weapon against deadly diseases. At the same time, the effective treatment depends on factors that would not be suspected for years to impact the successful therapy.

Receiving a simple thank you, spending time with peers and further developing their expertise, are all factors that make veterinarians feel good at work, according to a new study by researchers at the University of Adelaide.
