ARCTIC ENVIRONMENT GENETIC STUDY
Alaska Native genomes show selection signals potentially linked to life in the Arctic; researchers identified variants in pathways associated with high-latitude conditionsAlaskan Native genomes show adaptation signals potentially linked to cold environments. Researchers compared these signals with populations...- Jeju's Haenyeo women have spent generations diving without oxygen tanks; a 2025 study found their hearts slow dramatically underwater, likely shaped by years of trainingThe Haenyeo women of South Korea are renowned for their remarkable ability to dive deep without any oxygen tanks, gathering valuable resour...

- In the 1930s, just 9 to 20 foreign ant queens apparently stowed away on a ship; their descendants now infest more than 367 million U.S. acresA few fire ant queens arriving in Mobile, Alabama, in the 1930s established a widespread infestation. These invasive insects now infest ove...
- In 2019, an international team began monitoring Greenland's Petermann Glacier's floating ice tongue from space. 7 years later, 76.4 sq km broke away, creating a Manhattan-sized ice island, while two more could reduce the tongue by 254 sq kmGreenland's Petermann Glacier lost a large iceberg, its biggest since 2012. Scientists have monitored this glacier's floating ice tongue fo...

- In 2014, scientists compared EPAS1 DNA from 40 Tibetans and 40 Han Chinese and linked a high-altitude adaptation to Denisovan-like ancestry. 12 years later, the finding traced the genetic gift to an interbreeding event about 48,700 years agoIn 2014, scientists found a remarkable clue in Tibetan DNA. They compared the EPAS1 gene in 40 Tibetans and 40 Han Chinese and uncovered a ...
- In 2012, anglers and biologists reported strange black tumors on catfish in a Vermont-Quebec lake. Years later, genetic testing revealed the shocking outcome: The tumors are a rare contagious cancer spreading between fishBrown bullhead catfish in Lake Memphremagog are showing unusual black tumors, raising concerns among researchers. Genetic studies indicate ...

- The tamarin on Brazil’s R$20 note once had only around 200 left in the wild; Smithsonian zoologist Devra Kleiman helped build the breeding program behind its recoveryOnce on the brink of extinction, the golden lion tamarin saw its population dwindle to a mere 200 individuals. Thanks to Devra Kleiman's pi...
