Vultures are more than scavengers feeding on animal carcasses; they are important components of healthy ecosystems. By rapidly removing dead animals, they contribute to nutrient cycling and influence the availability of carrion to other…

Animal dung is far more than biological waste. Once deposited, it becomes a temporary ecosystem supporting dung beetles, flies, mites, nematodes, fungi and diverse microorganisms. These organisms break down organic matter, recycle…

Rivers do more than carry water to the sea. They transport sediment, nutrients and freshwater that help sustain deltas, wetlands and coastal ecosystems. When dams, water diversion and other human activities reduce this natural flow, the…

When a species disappears, the impact can extend far beyond the loss of a single organism. Species are connected through food webs, pollination, seed dispersal, competition and other ecological relationships. The disappearance of an…

Hidden beneath the Atlantic Ocean lies one of Earth's most powerful climate engines—the Atlantic Meridional Overturning Circulation (AMOC). This vast network of ocean currents transports heat, regulates rainfall and supports marine…

Ecosystems rarely collapse without warning. Long before forests decline, lakes become polluted or coral reefs disappear, nature often shows subtle signs that its resilience is weakening. Today, scientists are using satellite observations,…

A lake turning bright green may appear harmless, but it often signals a growing environmental crisis. Triggered by excessive nutrients, warming temperatures and pollution, harmful algal blooms are becoming increasingly common in freshwater…

Hidden inside seed banks are millions of tiny time capsules containing the genetic diversity that future agriculture may depend upon. As climate change, biodiversity loss and emerging crop diseases threaten global food security, these…

Freshwater is one of Earth's most limited yet essential resources, sustaining people, agriculture, industry and ecosystems alike. As climate change alters rainfall patterns, glaciers retreat, groundwater declines and pollution contaminates…

Every animal leaves behind tiny traces of its DNA in water, soil and even the air. Scientists are now using this invisible genetic fingerprint—known as environmental DNA (eDNA)—to monitor wildlife without disturbing it. From detecting…
