During the holidays most people worry about putting on a couple of pounds, but in addition they should be concerned about what they’re doing to their hearts. Every year during the holidays, emergency rooms like those at UCSD Medical Center see patients with symptoms of palpitations and light-headedness. Further evaluation usually confirms the patient has an abnormal heart rhythm, often atrial fibrillation, says Ajit Raisinghani, M.D., Director of the UCSD Non-Invasive Cardiac Lab. This condition, called “Holiday Heart”, is a result from over-indulgence of alcohol.
“Alcohol consumption can cause significant cardiac toxicity,” says Dr. Raisinghani. “Usually the patient experiences palpitations accompanied with a sensation of light-headedness. When these patients come into the ER we learn they’ve usually spent the weekend drinking. Most often they’re college kids who are otherwise healthy.”
Fortunately the condition resolves itself within 24 hours. But if not, the doctor will admit the patient to the hospital, administer medication to slow down the heart rate and keep watch until the heart rate returns to a normal sinus rhythm. It’s a heck of a way to spend the holidays.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
