Astronomers Detect Almond-Scented Molecule That Will Help Solve Interstellar Radiation Mystery

There’s an unidentified source of infrared throughout the universe. By looking at the specific wavelengths of the light, scientists think that it comes from carbon—but not just any carbon, a special kind where the atoms are arranged in multiple hexagonal rings. No one has been able to spot one of these multi-ring “polycyclic aromatic hydrocarbons,” or PAHs in space—even though the infrared emissions imply that these PAHs should make up 10 per cent of the universe’s carbon. Now, scientists have found a new hint. Read More >>

Life Could Have Evolved From These Ancient Chemical Reactions

Fundamentally, your body is just a crazy chemistry experiment. You put in food and oxygen, chemical reactions happen, and out comes energy and poop. But how did these reactions first begin? Some scientists think they have an idea. Read More >>
