This is the first in an occasional series on the origin of commonly used medicines. When epinephrine was first discovered at the turn of the 20th century, it was essentially a drug without a disease. In 1894, two British researchers — physician George Oliver and physiologist Edward Albert Sharpey-Schafer — discovered that the extract of […]

To be fair to donkeys, this is not justified. Nevertheless, when it comes to the law, rigidity and obstinance are, on occasion, […]
Astronomers closer to unlocking origin of mysterious fast radio bursts: New study by international team of scientists identifies polarization as key trait that may reveal the origin of the powerful millisecond-long cosmic radio explosions
Nearly 15 years after the discovery of fast radio bursts (FRBs), the origin of the millisecond-long, deep-space cosmic explosions remains a mystery. That may soon change, thanks to the work of an international team of scientists — including UNLV astrophysicist Bing Zhang — which tracked hundreds of the bursts from five different sources and found […]
Life arose on hydrogen energy, researchers suggest
How did the first chemical reactions get started at the origin of life and what was their source of energy? Researchers at the Heinrich Heine University Düsseldorf (HHU) have reconstructed the metabolism of the last universal common ancestor, LUCA. They found that almost all chemical steps used by primordial life to piece together the molecular […]
