Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity. The team examined recent gravitational wave experiments, showing it is possible to shield large objects from strong influences from the thermal and seismic environment to allow them to evolve as one quantum object. This decoupling from the environment enables measurement sensitivities that would otherwise be impossible.

Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual.

Researchers aim to streamline the time- and resource-intensive process of screening ligands during catalyst design by using virtual ligands.

Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. Engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency.

With the insertion of a little math, researchers have shown that neuromorphic computers, which synthetically replicate the brain's logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing. Neuromorphic simulations employing random walks can track X-rays passing through bone and soft tissue, disease passing through a population, information flowing through social networks and the movements of financial markets.

Around the world, between 40 and 50 volcanoes are currently erupting or in states of unrest, and hundreds of millions of people are at risk of hazards posed by these potentially active volcanos. Yet, despite the profound hazards posed to human life and property by volcanic eruptions, humanity still cannot reliably and accurately predict them, and even when forecasts are accurately made by experts, they may not afford ample time for people to evacuate and make emergency preparations.

A new discovery by physicists could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components. Frequency multiplication is a fundamental process in modern electronics.

A new analysis shows that researchers using machine learning methods could risk underestimating uncertainties in their final results.

A quantum ensemble -- a set of quantum states with their corresponding probabilities -- is essential to the encoding of classical information for transmission over quantum channels. But receivers must be able to 'guess' the transmitted quantum state, incurring a cost called 'guesswork.' Recently, researchers have derived analytical solutions of the guesswork problem for when the ensemble is subject to a finite set of conditions. The results constitute a first step towards future algorithms for quantum software.

Much of a centuries-old debate over where and how new bird species form has now been resolved. Researchers have provided evidence that birds in mountainous areas -- where the vast majority of the planet's species live -- have left lowland habitats for higher and higher mountain elevations throughout their evolution. Millions of years of climatic fluctuations have contributed to pushing bird species upslope -- as is probably happening now.

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.

The soils and vegetation of Patagonia's fjord regions form a unique and highly sensitive ecosystem that is closely linked to marine ecosystems, sediment deposition and carbon storage in the ocean. A research team has been working on reconstructing the climate history of this region in this extremely wet, rainy and inaccessible fjord and island zone of the Patagonian Andes in southern Chile. Due to its location, the area is a key region for understanding the history of the southern westerly wind belt within the global climate system.

Dinosaurs went extinct 65 million years ago, mammoths 4,000 years ago, and the Christmas Island Rat 119 years ago. Since becoming a popular concept in the 1990s, de-extinction efforts have focused on grand animals with mythical stature, but now a team of paleogeneticists has turned their attention to Rattus macleari, and their findings provide insights into the limitations of de-extinction across all species.
