The speed of electricity may refer to the movement of electrons or energy

In the 18th century, various experiments, including one in which monks holding an iron wire were shocked, suggested that electricity traveled at infinite speed. Advancements in technology, recognizing that electric currents were moving electrons, and the development of the theory of electromagnetism showed that electric signals can travel at near light speed, despite electrons moving much slower.

The process of electronic funds transfer was approved in the US in 1978

An electronic funds transfer is the transfering of money from one bank account to another via computer-based systems. When it was first introduced, it was revolutionary. A video from 1980 aimed to explain the value of electronic funds transfer to consumers at the time.

All computers are defined by their ability to input, store, process, and output data

Why millions of telegrams are still sent every year

Telegrams enabled much faster communication across distances when they were invented in the 1800s, but they became generally obsolete after emails and cell phones were widely adopted. So why are 17 million still sent every year? A combination of factors: the legal requirement to send paper documents far and fast, the resistance to updating processes, and nostalgia.

UNOS oversees the entire US organ donation system

The United Network for Organ Sharing is a private, nonprofit organization that manages much of the US organ donation and transplantation system under a federal contract. Medical urgency, blood type, organ size, and geography of the donor and recipient are all factors determining how someone who needs an organ is matched with someone who donated an organ.

Is human evolution speeding up or slowing down?

In the past 3,000 years, many populations have evolved genetic adaptations to their local environments. People in Siberia and the high arctic are uniquely adapted to survive extreme cold. The Bajau people can dive 70 meters and stay underwater for almost 15 minutes. So what are other recent changes? And will our technological innovations impact our evolution?

What are universal vaccines?

As viruses mutate and develop, vaccines have to adapt, leading to regular recommended injections like flu shots. Researchers are working to develop universal vaccines that aim to protect against multiple virus variants if not entire virus families. These vaccines work by creating broadly neutralizing antibodies (bnAbs) that target aspects of viruses that don't typically mutate and are integral to the virus' survival.

When was the first blood transfusion?

In the 1600s, an English doctor transferred the blood from one dog to another via quills. The procedure ended when one of the dogs died. This article details the early days of blood transfusions, which turned toward humans shortly after the 1666 dog experiment and involved putting the blood of a sheep into a human recipient (who reportedly survived the encounter).

Two-thirds of antibiotic classes were made between the 1940s and 1960s
