NASA is planning an exhilarating mission for late 2028 that will test nuclear electric propulsion well beyond our planet. The SR-1 Freedom spacecraft will journey past Mars, releasing three helicopters similar to Ingenuity to explore the Martian landscape and locate potential subsurface ice reserves. The insights gained from this venture will not only refine our understanding of nuclear-powered spacecraft but also enhance future lunar energy systems and propulsion methods.

Recent research highlights that Earth microbes, including select bacteria and fungi, may endure in the shaded pockets of the lunar south pole for several days. Among them, Aspergillus demonstrates remarkable resilience, surviving in some conditions for over a week. These findings pose significant implications for future lunar exploration, particularly for NASA's Artemis missions, as understanding these organisms is vital for scientific advancements.

Researchers at Koc University have developed a method that uses photogrammetry, 3D printing and embedded sensors to repair damaged ancient pottery. The customised 3D-printed sections can replace missing parts while monitoring temperature, humidity, pH and physical stress. Tested on maritime amphorae from Türkiye and Italy, the approach could help conservators track changes and support long-term preservation.

In a groundbreaking initiative, a student has engineered a teabag designed to extract arsenic from polluted water. This clever pouch incorporates eggshells and magnetic iron oxide, successfully removing over ninety-eight percent of arsenic during rigorous laboratory assessments. Researchers are also investigating possibilities for its reuse and economical manufacturing. This innovation represents a significant leap towards providing accessible and safe drinking water.

After a long absence of 20 years, scientists in Barbados have triumphantly rediscovered the world's tiniest snake, the Barbados threadsnake. This remarkable find, located under a rock during an ecological survey, measures just 3 to 4 inches long. The rediscovery is crucial for understanding the species' diminishing forest habitat, and conservationists are optimistic that this will bolster efforts to protect the remaining forests on the island.

In 2005, scientists examined cricket reproduction on the International Space Station, where embryos grew under microgravity conditions. Interestingly, larvae emerged sooner than those on Earth, suggesting that microgravity affects developmental speed while preserving key neural structures. This research is vital for comprehending how life forms adjust to lesser gravitational forces, expanding our knowledge of development beyond Earth.

Scientists have frozen the liquid inside a special optical fibre to -196°C, creating conditions where light and sound interact more than 1,000 times more strongly than in ordinary fibres. The team found that the frozen fibre could still guide light and hypersonic sound waves. The breakthrough also helped researchers demonstrate optoacoustic memory, which could have potential applications in lower-energy photonic computing, quantum information processing and high-precision sensing.

Conservationists attempted a large-scale rat eradication on Henderson Island in 2011.About seventy-five tonnes of poisoned bait were spread across the remote South Pacific island.However, a small number of rats survived the intensive campaign.Within two years, the rat population had recovered significantly to former levels.This event underscores the difficulty of achieving complete eradication and the resilience of invasive species.

At the recent Beijing Robot Games, humanoid robots set remarkable new benchmarks in speed and agility. One robot sprinted 100 meters in an astonishing 9.39 seconds, shattering Usain Bolt's record. Another demonstrated incredible prowess with a standing high jump of 2.88 meters, surpassing human limits. These milestones reflect China's advancements in the robotics field, yet experts caution that widespread adoption remains a future prospect.
