The critical system of ocean currents which loops around the Atlantic Ocean is weakening and could be far closer to collapse than previously thought, according to two new studies — an event which ...

Cardiogenic shock is characterized by depression of cardiac function that leads to low blood pressure, coronary ischemia, and further decreased cardiac contractility resulting in tissue hypoxemia. The ...

In May 2023, a group of scientists gathered in Agros, Cyrpus, for an AGU Chapman Conference, “Hydrothermal Circulation and Seawater Chemistry: What’s the Chicken and What’s the Egg?” They discussed ...

In 2026, Bradley Maron MD’03 will assume the role of editor-in-chief of Circulation, one of the leading cardiovascular medicine research journals. Maron’s appointment was announced at an American ...

They’re the farthest points from your heart, often stuffed into shoes and easily forgotten. But your toes might be sending important messages about your cardiovascular health long before other ...

A crucial ocean-current system seems unlikely to collapse even in the face of severe climate change ― despite predictions that it would disintegrate if Earth continues to warm. That’s the ...

The way climate change affects thermodynamic signals, such as atmospheric temperatures, is relatively well understood. Its effects on atmospheric circulation, however, are more complex because the ...
