Investigating the dynamics that reshape permafrost environments

When permafrost thaws, water can flow more quickly through the ground, creating a complex subsurface flow system. Researchers at the Barrow Environmental Observatory in Alaska gained insight into this process by taking daily ...

Hydrology controls lithium isotopes in rivers and seawater

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ~9‰ increase during the Cenozoic, which is interpreted as the reflection of either a change in continental silicate weathering rate or weathering ...

Micro-device could pick up early signs of heart attack or stroke

In Australia each year, approximately 55,000 people suffer a heart attack, with a similar number suffering from stroke. Many are caused by blood clots that block the flow of blood to the heart, often in at-risk individuals ...

Hydrodynamic model of fish orientation in a channel flow

For over a century, scientists have sought to understand how fish orient against an incoming flow, even without visual and flow cues. In a study published in eLife, researchers explore a potential hydrodynamic mechanism of ...
