Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

We all know the equation – hydrogen plus oxygen equals water. But now scientists have captured molecular-scale video of that famous meeting in action, which could lead to a new way to generate large ...

An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable -- a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining ...

During Cold War-era plutonium production at what is now the Department of Energy's Hanford Site in Washington State, aluminum ...

In a quiet lab at Northwestern University, a team of scientists peered into a high-powered microscope, holding their breath. What they saw was something no human had ever witnessed: the moment ...

Oct. 10 (UPI) --Until recently, astronomers assumed hydrogen molecules fueled star formation in young galaxies. But new research suggests atomic hydrogen may be equally important to star formation. In ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

THE recent statement by Kreevoy and Eyring 1, based on theoretical considerations, that the hyperconjugation energy is approximately proportional to the number of α-hydrogen atoms, is supported by an ...
