From a serene view of planet Earth, through the heart of the Milky Way and out to far-flung galaxies, take an armchair tour of the Universe with these dazzling images

Global population growth is slowing, will level off, and one remarkable day, decline. This day will mark the dividing line – the definitive transition –…
Scientists first detected ripples in the fabric of space-time by using radio signals, but now a team of astronomers has detected the same effect at optical wavelengths.

Take, for example, the latest Neuroscience-of-Religion news item to make the rounds, this one claiming that critical thinking undermines religious belief. Based on two studies from The Journal of Experimental Psychologies and Science, it…
After 50 years of searching, physicists have spotted the fingerprint of radioactive plutonium, revealing the secrets of this complex molecule behind nuclear weapons. The researchers found the “plutonium signal” using nuclear magnetic resonance spectroscopy, which is often used to peer into the electronic structure of atoms and molecules. Their findings, detailed in a recent issue…
Another study casts doubt on the famous arsenic-life findings, showing the bacterium actually grabs phosphorus wherever it can be found.
To Joel Cohen, a professor of populations at Columbia, whether the Earth will be able to sustain 7 billion humans, 9 billion or 10 billion will “depend on choices we and future generations make.” Author Metanexus Editors
