There is no doubt that one of the hallmarks of the modern space age is that it is becoming increasingly democratic. In addition to more space agencies entering the fray, private aerospace companies are contributing like never ...
A new study by chemists at the University of Arkansas shows that X-ray crystallography, the standard method for determining the structure of proteins, can provide inaccurate information about a critical set of proteins—those ...
When the mysterious object known as 'Oumuamua passed Earth in October of 2017, astronomers rejoiced. In addition to being the first interstellar object detected in our solar system, its arrival opened our eyes to how often ...
According to the most widely accepted cosmological models, the first galaxies began to form between 13 and 14 billion years ago. Over the course of the next billion years, the cosmic structures now observed first emerged. ...
