Science Advances is trending for new studies on climate change, ancient species, and health risks—keeping us sharp on science’s latest.
New DNA analysis reveals that fossils previously thought to be tigers in Japan are actually extinct cave lions from the Late Pleistocene, indicating lions once inhabited the region. The findings challenge previous assumptions about Japan's prehistoric fauna and suggest land bridges facilitated lion migration from Eurasia.
Recent studies confirm that global warming has accelerated significantly since 2015, with the Earth heating at about 0.35°C per decade—nearly double the previous rate. February 2026 saw extreme rainfall and flooding in Western Europe, while Arctic sea ice reached its third-lowest extent on record. Compound heat and drought extremes are rising rapidly, increasing risks of flash droughts and ecosystem tipping points.
Recent studies reveal significant undercounting of COVID-19 deaths and rising heart disease among women aged 25-44. New guidelines aim to improve cholesterol screening and reduce mortality, especially in vulnerable populations. These findings highlight ongoing health disparities and the need for targeted interventions.
