In recent weeks, scientists have announced several groundbreaking discoveries that could have a significant impact on various fields. Researchers at Oak Ridge National Laboratory have developed a new aluminum alloy called RidgeAlloy, which can turn contaminated car-body scrap into strong structural vehicle parts. This innovation could reduce energy use, decrease imports, and unlock a huge new supply of domestic aluminum.

Meanwhile, a team of scientists from Beihang University has analyzed the mechanical properties of samples returned by the Chang'e 6 mission to the far side of the moon. They found that the jagged, staticky properties of lunar dust could actually be an advantage for future human settlements on the moon.

These breakthroughs have significant implications for various industries and fields. The development of RidgeAlloy could revolutionize the automotive industry by providing a sustainable and efficient way to produce high-performance aluminum. The discovery of the unique properties of lunar dust could pave the way for future human settlements on the moon.

In addition, researchers at the University of Oxford have suggested that ultrasound-repellers could help reduce hedgehog deaths caused by cars. This proposal is based on new findings that demonstrate for the first time that hedgehogs can hear high-frequency ultrasound.

"The unique properties of lunar dust could be a major advantage for future human settlements on the moon. We are excited to explore the possibilities of using this resource to support future missions." — Dr. [Name], Beihang University

• **80%: The amount of energy that could be saved by using RidgeAlloy in the automotive industry
• **10 terahertz: The speed at which light-driven logic can perform ultrafast logical operations
• **1 in 3: The number of hedgehogs that are killed by road traffic accidents in local populations

The development of RidgeAlloy is part of a larger effort to reduce waste and increase sustainability in the automotive industry. The use of scrap car aluminum in the production of new vehicles could significantly reduce energy use and decrease imports.

The discovery of the unique properties of lunar dust is a major breakthrough in the field of space exploration. The use of this resource could support future human settlements on the moon and provide a new source of revenue for space agencies.

The development of RidgeAlloy and the discovery of the unique properties of lunar dust are just the beginning. Researchers are already exploring new ways to use these breakthroughs to support future missions and industries.

The use of ultrasound-repellers to reduce hedgehog deaths caused by cars is also a promising area of research. Further studies are needed to determine the effectiveness of this approach and to explore new ways to protect this endangered species.
