As China’s vast electrical grid relies more on wind, solar and hydropower, it faces a growing risk of power shortages due to bad weather – and that could encourage the use of coal plants

How can Uranus be used to indirectly study its moons and identify if they possess subsurface oceans? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists investigated using passive radar sounding methods from Uranus to study its five largest moons: Miranda, Ariel, Umbriel, Titania, and Oberon. This study has the potential to help researchers better understand the formation and evolution of Uranus and its largest moons despite a spacecraft not currently visiting Uranus.

When galaxies run out of primordial hydrogen and helium, they cease star formation, shifting to primarily long-lived red stars. These galaxies are considered "red and dead." It usually takes billions of years for galaxies to run out of hydrogen, but now astronomers using JWST have found examples of galaxies that have already stopped forming stars just 700 million years after the Big Bang, much earlier than predicted by cosmological models.

An international team has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing.

Scientists have repurposed smartphone camera sensors to create a detector capable of tracking antiproton annihilations in real time with unprecedented resolution. This new device can pinpoint antiproton annihilations with a resolution of about 0.6 micrometers, a 35-fold improvement over previous real-time methods.

New York City's automated speed cameras reduced traffic crashes by 14% and decreased speeding violations by 75% over time, according to new research. The research revealed most cameras achieve their safety purpose within six months, with violations dropping and staying low -- showing drivers have changed behavior to drive more slowly and the cameras are working as intended, to deter speeding.

Nostalgia for video games seems to be strongest for those played during childhood – at least for Nintendo Switch players

Sometimes, the best way to learn how to do something is just to do it. That is especially true if you're learning to do something using a specific methodology. And in some cases, the outcome of your efforts is something that's interesting to other people. A team from across the European Union, led by PhD candidate Domenico D'Auria, spent a few days last September performing just such an exercise - and their work resulted in a mission architecture known as the Planetary Exploration Deployment and Research Operation - Venus, or PEDRO-V.

NASA's Perseverance Rover is an ambitious mission. Along with its day-to-day exploration, the rover carried an experimental rotorcraft and is also caching samples for eventual return to Earth. But there's another aspect to its mission that's hidden in the glare of its ambitions. The rover is busy testing five different spacesuit materials.

When we move, it's harder for existing wearable devices to accurately track our heart activity. But researchers found that a starfish's five-arm shape helps solve this problem. Inspired by how a starfish flips itself over -- shrinking one of its arms and using the others in a coordinated motion to right itself -- scientists have created a starfish-shaped wearable device that tracks heart health in real time.
