🇨🇳 Chinese scientists develop CO₂-powered Li-CO₂ battery for Mars rovers and robots

Researchers in China have created a lithium-carbon dioxide (Li-CO₂) battery with enhanced energy efficiency, offering potential for lighter, high-density batteries suitable for Mars rovers and robots. By adding molybdenum disulfide and cobalt pentlandite to the porous cathode, the battery achieves over 81% energy efficiency while directly utilizing CO₂, transforming it into power rather than emissions. This technology, while promising, requires further development for electrolyte stability and anode design to enable commercial applications. The research findings were published in PNAS.

🇵🇱 Polish engineers develop amphibious robot dog to transform rescue and industrial operations

Polish engineers at MAB Robotics have unveiled the Honey Badger robot, an amphibious quadruped capable of walking underwater, ideal for rescue missions and industrial inspections. The updated Honey Badger 4.0 features advanced capabilities like LiDAR, gas sensors, and 5G connectivity, allowing it to handle complex tasks in challenging environments, including heating tunnel and water system inspections. This versatile robot’s adaptability to both land and water could greatly enhance safety and efficiency in rescue operations.

🇸🇬 Singapore scientists develop grain-sized soft robots for precise, controlled drug delivery

Scientists in Singapore have created miniature, grain-sized soft robots that can be directed by magnetic fields to deliver targeted drug doses with high precision. Unlike previous models, these robots can transport and dispense up to four different medications in programmable doses, enhancing therapeutic accuracy and minimizing side effects. Crafted from biocompatible materials, the robots can navigate complex bodily environments, even controlling drug release timing to treat conditions like cancer. These advancements, published in Advanced Materials, represent a step toward highly personalized treatments with minimized invasiveness.

🇺🇸 American researchers develop HarmonyCloak to protect music from AI replication without changing sound quality

Researchers in the U.S. have introduced HarmonyCloak, a tool that protects music from AI learning while preserving its sound quality for human listeners. By adding barely perceptible audio modifications, HarmonyCloak prevents generative AI models from extracting information from songs, effectively rendering the music “unlearnable” to AI. This innovation allows artists to share their work publicly without fear of unauthorized AI replication, marking a significant step toward copyright protection in the digital age.

🇺🇸 U.S. researchers develop portable, low-cost cancer detection device for rapid diagnosis

American researchers have created a portable biochip device that detects colorectal and prostate cancers in about an hour, providing a low-cost, accessible solution for early cancer detection. This microfluidic device, which uses a color-changing paper to detect cancer biomarkers, costs only a few dollars and is especially beneficial for rural and low-resource areas lacking advanced diagnostic tools. The device is highly sensitive, identifying even small cancer biomarker amounts, which can aid in diagnosing cancer in its early stages and potentially improve survival rates. The research findings were published in the journal Lab on a Chip.
