This was Mastercard in March: You probably do it every day without a second thought — shop online with your credit card, or install an update on your phone, or send a confidential file to a co-worker.


Mastercard’s efforts include a pilot to test whether quantum key distribution would work on its complex global network.

The technology is designed to treat the condition atrial fibrillation, or irregular heart rhythm. This is in a way that carries a lower risk of complications and shorter anaesthesia time (when compared to traditional treatment).

The new technology took eighteen years to develop. In recent months, pulsed field ablation has been approved by the U.S. Food and Drug Administration (FDA) and the acceptance marks a milestone in heart treatment.

The process involves the use of microsecond-scale, high-voltage electrical fields to cause irreversible electroporation and destabilization of cell membranes, according to the New England Journal of Medicine.

How did everything begin? It’s a question that humans have pondered for thousands of years. Over the last century or so, science has homed in on an answer: the Big Bang.

This describes how the Universe was born in a cataclysmic explosion almost 14 billion years ago. In a tiny fraction of a second, the observable universe grew by the equivalent of a bacterium expanding to the size of the Milky Way. The early universe was extraordinarily hot and extremely dense. But how do we know this happened?

Let’s look first at the evidence. In 1929, the American astronomer Edwin Hubble discovered that distant galaxies are moving away from each other, leading to the realisation that the universe is expanding.
