The vast expanse of the night sky, a canvas dotted with countless stars, is about to unveil a rare and spectacular phenomenon. Brace yourself for a stellar light show as T Coronae Borealis, a seemingly unremarkable star nestled within the constellation Corona Borealis, is on the brink of a dramatic nova explosion.

T Coronae Borealis, affectionately known as T CrB, is no ordinary star. It’s a binary system, a celestial pattern of two stars locked in a gravitational embrace.

At the heart of this cosmic process lies a white dwarf, the incredibly dense remnant of a once-mighty star. Its partner, a bloated red giant, is in the twilight years of its existence, slowly shedding its outer layers under the relentless pull of the white dwarf’s gravity.

From mundane chores to complex interactions, RoboCasa trains robots to navigate the real world:

Researchers have developed a large-scale simulation framework for training general-purpose robots in diverse, everyday settings.

The framework, called RoboCasa, provides access to thousands of 3D assets over more than 150 object categories, as well as dozens of furniture and appliances that may be interacted with.

Collectively, the US’s 5 million solar installations can generate more than 179 gigawatts (GW) of electricity. Based on current trends, the SEIA claims that the US’s total solar capacity will soar to 673 GW by 2034, providing enough electricity to power 100 million homes.

The US will likely need to do better than that to meet the Biden Administration’s goal of 100% clean electricity by 2035, though. To decarbonize the grid by then, the Department of Energy (DoE) expects we’ll need as much as 1 terawatt (1,000 GWs) of solar capacity, enough for solar to meet 30–50% of the US’s electricity demand by itself.

The transition from traditional 2D to 3D microfluidic structures is a significant advancement in microfluidics, offering benefits in scientific and industrial applications. These 3D systems improve throughput through parallel operation, and soft elastomeric networks, when filled with conductive materials like liquid metal, allowing for the integration of microfluidics and electronics.

The reliable generation of random numbers has become a central component of information and communications technology. In fact, random number generators, algorithms or devices that can produce random sequences of numbers, are now helping to secure communications between different devices, produce statistical samples, and for various other applications.

Scientists found that water in our solar system is likely billions of years older than the sun by studying the protostar V883 Orion, linking water from the interstellar medium to our solar system.

This research suggests that water in our solar system was formed long before the sun, planets, and comets, indicating that planetary systems.

A bioresorbable, wireless hydrogel (metagel) sensor, encompassing both biodegradable and stimulus-responsive hydrogels for ultrasonic monitoring of intracranial signals, was implanted into intracranial space with a puncture needle and deformed in response to physiological environmental changes.
