Two-dimensional transition metal dichalcogenides (TMDCs), as a new generation of semiconductors with the potential to surpass the limitations of silicon-based technology, have long lacked empirical research on their stability in space environments. The Chinese research team, leveraging the “Shijian-19” recoverable satellite, has pioneered in-orbit verification experiments for 2D semiconductor materials and devices. The study demonstrates that these materials can maintain excellent optical and electrical performance even under extreme space conditions, providing critical experimental evidence for the development of high-performance space electronic devices.

Scientists from Nagoya University in Japan have developed an innovative cooling device—an ultra-thin loop heat pipe—that significantly improves heat control for electronic components in smartphones and tablets. This breakthrough successfully manages heat levels generated during intensive smartphone usage, potentially enabling the development of even thinner mobile devices capable of running demanding applications without overheating or impeding performance.

The research, published in the journal Applied Thermal Engineering, addresses one of the most critical challenges in mobile device engineering: effectively cooling increasingly powerful components within the confined space of slim mobile devices. The team's solution provides more efficient heat management without increasing device thickness, which could allow manufacturers to push performance boundaries while maintaining or even reducing size. This may lead to next-generation smartphones and tablets that deliver sustained high performance without compromising on design or user experience.

Earth’s rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet’s molten youth using advanced quantum mechanical simulations, revealing nitrogen’s secret: under extreme pressure, it chose to hide in the iron core 100 times more than the mantle. This solved why Earth’s volatile ratios involving nitrogen look odd. The findings suggest the necessary ingredients for developing a habitable world may have been settled in the early Earth.

Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the universe's secrets. If their existence is confirmed it would "effectively break current models of galaxy numbers and evolution". The possible galaxies may also provide the missing piece of the puzzle for the energy generation in the universe in infrared light. That's because their combined light would be enough to top-up the energy budget of the universe to the maximum we observe, effectively accounting for all remaining energy emission at these long wavelengths.

Before humans can colonize the moon or Mars, scientists and engineers must first develop techniques for building permanent structures and pressurized habitats in harsh, thin-atmosphere and low-gravity environments.

Dr. Wei Li, an assistant professor of mechanical engineering in the Erik Jonsson School of Engineering and Computer Science at The University of Texas at Dallas, is developing a virtual lunar welding platform to troubleshoot assembling large structures in such conditions.
