A heart rhythm disturbance that affects more than 2 million Americans is twice as likely to recur in patients with untreated sleep apnea, according to a Mayo Clinic study published in the May 27 edition of Circulation: Journal of the American Heart Association. Obstructive sleep apnea (OSA) is a condition that causes people to repeatedly stop breathing during sleep.
Atrial fibrillation (AF) is the most common sustained heart arrhythmia and can have serious consequences. When the upper chambers of the heart quiver rapidly and erratically -- as many as 400 times per minute -- blood does not move efficiently through the heart. This pooling blood is more likely to clot, leading to heart attacks or strokes. AF also can lead to heart failure by causing the hearts main pumping chambers, the ventricles, to contract rapidly -- often more than 100 beats per minute.
AF treatment involves using electrified paddles on the chest to shock the heart back into the proper rhythm, a procedure called cardioversion. Medications can help maintain normal rhythms, but lasting results are difficult to achieve; more than half of patients fall back into AF within one year.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
