Quasi-periodic oscillations (QPOs) are a rare phenomenon in active galactic nuclei. They have been observed to occur at periods ranging from minutes to hours, days, weeks, and even years across the electromagnetic spectrum. ...

Spotted lanternflies are adapting to the pressures of city life such as heat, pollution, and pesticides, according to genomic analyses of the invasive insects in the US and their native China. The findings, published in the ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe capable of producing such ...

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing ...

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led by Quanshui Zheng at ...

Research papers in peer-reviewed academic journals are at the heart of academic integrity. New ideas and discoveries are vetted and checked by experts in the field as the boundaries of scientific knowledge are pushed forward. ...

Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...

Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...

The world is in the middle of a peptide drug revolution. These short chains of amino acids—the building blocks of proteins—sit at the heart of some of the most successful medicines ever created, from weight-loss injections ...

Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously ...

Some dogs are seemingly more talented than others. So-called gifted word learners (GWL) are rare canines that can rapidly learn the names of toys, a skill that most dogs don't possess. To understand why this is so, researchers ...

A pair of US researchers have developed a new model to tackle a deceptively simple problem: how a small block of ice melts while floating in calm water. Using an advanced experimental setup, Daisuke Noto and Hugo Ulloa at ...
