For years, the global scientific community has sought ways to unlock a sustainable, boundless energy source. The quest has explored everything from Moon crystals to boundary-defying molecules. However, recent groundbreaking research suggests that we may have discovered a means to harness energy generation, inspired by the incredible efficiency of plant photosynthesis.

This breakthrough came to light through innovative research where scientists successfully replicated the natural process of photosynthesis to create methane. This high-energy-density fuel is generated using only water, carbon dioxide, and sunlight. Their findings are documented in a newly published paper in ACS Engineering. If scaled up, this new process could revolutionize the energy landscape, potentially replacing solar panels as a primary source of clean, infinite energy—something researchers have been striving to achieve for decades.

Study Reveals Soil as Earth’s Premier Biodiversity Hotspot

A groundbreaking study has unveiled a stunning revelation: more than half of all species on Earth inhabit the soil, making it the most biodiverse habitat on our planet. This revelation significantly surpasses previous estimates from 2006, which suggested that 25% of life had a soil-based foundation.

Published in Proceedings of the National Academy of Sciences, the research marks a turning point in our understanding of biodiversity. Soil, often overlooked in discussions of nature protection due to its enigmatic complexity, is now recognized as the epicenter of life’s rich diversity.

A metallic alloy of chromium, cobalt, and nickel is over 100 times tougher than graphene and gets even more resistant to damage at extremely low temperatures.

Researchers have proven that a metallic alloy of chromium, cobalt and nickel is officially the toughest material on Earth — more than 100 times tougher than the wonder material graphene.

In a new study published Dec. 1 in the journal Science, researchers subjected the ultra-tough alloy to extremely cold temperatures, in order to test how fracture-resistant the material is. Scientists have known for years that this alloy is one tough cookie — however, to the team’s surprise, the alloy only became tougher and more resistant to cracks as temperatures plummeted. 

This super-resistance to fracture is in stark contrast to most materials, which only become more brittle in freezing temperatures, according to the study authors.

“People talk about the toughness of graphene, and that is measured at just 4 megapascals per meter,” study co-author Robert Ritchie), a professor of engineering at the University of California Berkeley and senior faculty scientist at the Lawrence Berkeley National Laboratory, told Live Science. “The toughness of aluminum alloys used in aircraft is 35 megapascals per meter. This material has a toughness of 450 to 500 megapascals per meter… these are mind-boggling numbers.” 

The potential applications of such a tough material range from space infrastructure to fracture-resistant containers for clean energy uses here on Earth. However, Ritchie noted, two of the alloy’s three elements (nickel and cobalt) are prohibitively expensive, limiting the alloy’s usefulness to the laboratory for the foreseeable future.

Sound vortex generation enabled by the spin-orbit interaction in real space.

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientists’ previous beliefs about the sound wave, opening an avenue to the development of novel applications in acoustic communications, acoustic sensing, and imaging.

The research was initiated and co-led by Dr. Wang Shubo, Assistant Professor in the Department of Physics at CityU, and conducted in collaboration with scientists from Hong Kong Baptist University (HKBU) and the Hong Kong University of Science and Technology (HKUST). It was published in Nature Communications, titled “Spin-orbit interactions of transverse sound.”
