From Earth to Space: Test technology with lava tubes for future space exploration
The DLR scout roller is designed to explore the complex terrain of the lava tube. Credit: Roy LichTenheldt, DLR Are the ancient lava pipes in the Canary Islands common to space exploration? For the robot team, I knew quite a lot. Our researchers have traveled to Lanzalot, 18,000 km away from the home of Brisbane, and tested navigation and mapping…

New materials like chain mail could be the future of armor
This diagram shows how X-shaped monomers interconnect to create the first 2D mechanically bonded polymer. Similar to chain mail, this material exhibits excellent strength. Credit: Mark Seniw, Northwestern University Center for Regenerative Nanomedicine In an amazing feat of chemistry, a Northwestern University-led research team has developed the first two-dimensional (2D) mechanically interlocked material. Nanoscale materials, similar to the interlocking links…

Scientists look to the mid-Pliocene to learn about the future behavior of the East Asian summer monsoon
A view of northeastern East Asia after a midsummer rain. Credit: He Linqiang The East Asian summer monsoon (EASM) is the most northerly monsoon system and is characterized by its pronounced seasonal march. It is characterized by a gradual shift northward in the rainfall stages, starting with the pre-rainy season in southern China in mid-May and ending in mid-June to…

Room-temperature non-reciprocal Hall effect could heat up future technology development
The researchers deposited textured platinum nanoparticles, represented by red triangles, onto a silicon semiconductor, represented by blue squares. Electrons, represented by white circles and arrows, scatter asymmetrically from the nanoparticles, causing a voltage, represented by yellow arrows, flowing perpendicular to the current, represented by black arrows, applied to the semiconductor. The relationship between voltage and current can be described mathematically…

China’s child policies will increase future carbon emissions, researchers say
Credit: Unsplash/CC0 Public Domain Relaxing restrictions on family size will make it harder for China to meet its goal of becoming carbon neutral by 2060, according to a new study by UCL researchers. The paper, published as a Policy Brief in the journal Nature Climate Change, is the first study to analyze the impact of national population policies on future…
