Modern life clashes with human biology shaped by nature, anthropologists say

Evolutionary anthropologists argue that human physiology, honed over hundreds of thousands of years for active, nature-rich hunter-gatherer lives, is poorly suited to the chronic pressures of industrialized environments. This mismatch, they say, is contributing to declining fertility and rising rates of inflammatory disease, and should prompt a rethink of how cities and societies are designed.
Microscopic algae in the ocean, vital for producing much of Earth's oxygen, depend on iron to fuel photosynthesis, according to new research from Rutgers University. When iron is limited, these phytoplankton waste energy, potentially disrupting marine food chains amid climate change. Field studies in the Southern Ocean highlight how this micronutrient shortage could lead to declines in krill and larger marine animals like whales and penguins.

A meltwater lake on Greenland's 79°N Glacier, formed in 1995, has undergone sudden drainages that are fracturing the ice in unusual triangular patterns. These events, accelerating in recent years, raise concerns about the glacier's long-term stability amid warming temperatures. Scientists are studying whether it can recover from these disturbances.
International climate scientists have warned in a new report that tropical coral reefs have already crossed their tipping point due to rising ocean temperatures. The Global Tipping Points Report 2025 highlights risks of cascading failures in other climate systems if global warming exceeds 1.5°C. The findings come ahead of the 30th World Climate Conference in Brazil.

Scientists have found that global sea levels are climbing more quickly than at any time in the past 4,000 years, posing severe risks to China's major coastal cities. The rapid rise, driven by warming oceans and melting ice, combines with land subsidence from human activities like groundwater pumping. Cities such as Shanghai are implementing measures to stabilize the ground amid these threats.
