This New Treatment Just Changed Everything For Patients With Irregular Heartbeats

And it involves blasting the heart with radiation.

Each year, 325,000 Americans die from a surprisingly little-known condition that affects the rhythm of their heartbeats. In many cases, the patients are battling a serious illness, recurring infections, or a high risk of heart attack and have electrical implants to regulate their heartbeats. When these electrical systems get short-circuited, however, the consequences can be lethal.


In an attempt to prevent these electrical glitches from taking hundreds of thousands of lives each year, researchers from Washington University in St. Louis came up with an unusual treatment: blasting their hearts with radiation. As extreme as that may sound, results from the first clinical trial show this new therapy actually works. The findings, which were published in the New England Journal of Medicine in December 2017, show that brief blasts of radiation effectively eliminate the rogue cells causing the electrical implants to malfunction.

University of California, San Francisco, medical professor Dr. Melvin Scheinman told The New York Times, “This is a game changer. There is no question that this will catch on.” Scheinman is not alone in this point of view. The University of Chicago’s director of cardiac electrophysiology, Dr. Roderick Tung, added his approval, calling the experimental procedure a “paradigm shift.”

When you look at the preliminary trial results, it’s easy to see why cardiologists are excited by the possibilities. The patients who’ve so far benefited from the treatment saw their instances of tachycardia (aka an abnormal heart rate) go from more than 2,000 times a month to just a handful of instances or none at all.

That said, doctors also agree the treatment requires further study before it can be implemented on a large scale. And because it takes a few weeks to see concrete results, the procedure won’t be helpful for those in need of emergency assistance. On this plus side, there is now a viable alternative for patients who’ve tried everything from drugs and invasive surgeries to regulate their unruly heartbeats.

One mystery in our universe is a step closer to being solved. NASA's Parker Solar Probe launched last year to help scientists understand the sun. Now, it has returned its first findings. Four papers were published in the journal Nature detailing the findings of Parker's first two flybys. It's one small step for a solar probe, one giant leap for mankind.



It is astounding that we've advanced to the point where we've managed to build a probe capable of flying within 15 million miles from the surface of the sun, but here we are. Parker can withstand temperatures of up to 2,500 degrees Fahrenheit and travels at 430,000 miles per hour. It's the fastest human-made vehicle, and no other human-made object has been so close to the sun.

McDonalds sells a lot of coffee. Over a billion cups a year, to be exact. All that coffee leads to a lot of productive mornings, but it also leads to a lot of waste. Each year, millions of pounds of coffee chaff (the skin of the coffee beans that comes off during roasting) ends up getting turned into mulch. Some coffee chaff just gets burned, leading to an increase in CO2.

Now, that chaff is going to get turned into car parts. Ford is incorporating coffee chaff from McDonalds coffee into the headlamps of some cars. Ford has been using plastic and talc to make its headlamps, but this new process will reduce the reliance on talc, a non-renewable mineral. The chaff is heated to high temperatures under low oxygen and mixed with plastic and other additives. The bioplastic can then be formed into shapes.

Nike has made a name for itself creating shoes for playing basketball, tennis, and running. But, let's be honest, how many people who wear Air Jordans or Lebrons actually play basketball versus watching it on television?

Now, Nike is releasing a new pair of shoes created for everyday heroes that make a bigger difference in all of our lives than Michael Jordan or Lebron James, medical professionals — nurses, doctors, and home healthcare workers.

Nike designed the shoe after researching medical professionals at OHSU Doernbecher Children's Hospital in Portland, Oregon to create the perfect one for their needs.
