Pacemaker channel discovery could lead to better heart drugs

The mechanism by which fat-related molecules called lipids regulate pacemaker ion channel proteins, which help control the heart rhythm, has been revealed in a study from researchers at Weill Cornell Medicine.

Pop-up factories beneath the cell membrane

A living cell is exposed to a variety of stimuli. Countless messengers dock on its surface, where receptors in the cell membrane receive the incoming "orders." Signaling cascades are then triggered inside the cell, which ...

Special cells contribute to regenerate the heart in zebrafish

It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group led by Prof. Nadia Mercader of the University of Bern now shows that certain heart muscle cells play a ...

Studying heart cells with nanovolcanoes

Researchers at EPFL and the University of Bern have developed a groundbreaking method for studying the electrical signals of cardiac muscle cells. The technology has numerous potential applications in basic and applied research—such ...

Lightning's electromagnetic fields may have protective properties

Lightning was the main electromagnetic presence in the Earth's atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...
