Road construction in Kerala threatened thousands of rare orchids growing on trees

13/11/2026
In an inspiring conservation effort, researchers successfully relocated more than 27,000 orchids from the threatened areas of Kerala's Western Ghats due to road expansion. This project aimed to assess the adaptation of these exquisite plants in new habitats, achieving a remarkable 71.4% survival rate. Notably, varying success rates were observed across locations, with urban wetlands proving to be the most beneficial.

Tiger's urine andscat reveals more than presence;researchers distinguished tigers from leopards

13/11/2026
In a groundbreaking study, researchers have thoroughly analyzed the chemical signatures found in the urine and scat of Bengal tigers and Indian leopards. By employing advanced analytical techniques, they not only distinguish between the two species but also glean insights into their health status. Early results show that these chemical markers could be invaluable for monitoring wildlife populations and developing more effective conservation strategies.

Underwater archaeologists exploring Lake Superior documented an 1880s flooded silver mine

13/11/2026
This summer, Parks Canada’s underwater archaeologists delved deep into Lake Superior to investigate fascinating historical remnants. Among their discoveries were the ruins of an 1880s silver mine and two railway cars lost since a 2008 derailment. Using a remotely operated vehicle, the team meticulously inspected mine structures, uncovering valuable insights into past industrial practices and deepening public interest in these submerged archaeological treasures.

NASA crashed a spacecraft into an asteroid in 2022; Europe's Hera probe reaches impact site to investigate if Earth can be saved from space rocks
