Kepler-34b Helps Explain How Circumbinary Exoplanets Form
Researchers reporting in the Astrophysical Journal Letters have found that the majority of circumbinary planets – planets that orbit two stars – were actually formed much further away from their binary stars and then migrated to their current locations. This artist’s impression shows an extrasolar gas giant orbiting a binary star system. Image credit: NASA / G. Bacon, STScI. There...

Scientists Create Map of Solar System’s Asteroids
Planetary scientists from Massachusetts Institute of Technology and European Space Astronomy have created a map of more than 100,000 asteroids throughout the Solar System, revealing the size, composition and location of each asteroid and showing that so-called ‘rogue’ asteroids are actually more common than previously thought. This is an artist’s impression of the triple asteroid system...

CERN Scientists Create Antihydrogen Atoms
Physicists from CERN’s Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA) project say they have produced at least 80 atoms of antihydrogen. Hydrogen’s electron and proton have oppositely charged antimatter counterparts in the antihydrogen: the positron and antiproton. Image credit: NSF. Current theories predict that the Universe could just as easily be made of antimatter...

Scientists Discover Odor Receptors in Human Lungs
According to a new study published in the American Journal of Respiratory Cell and Molecular Biology, human lungs have odor receptors. A diagram of the airway lining suggests how the pulmonary neuroendocrine cells (red) trigger a response to inhaled chemicals. When a chemical (orange triangle) docks on a receptor (black) they dump secretory chemicals (thin orange arrows), which have an immediate...

Scientists Identify Neanderthal Genes in Modern Human DNA
In two new studies, genetic researchers have shown that about 20 percent of the Neanderthal genome survives in modern humans of non-African ancestry and identified exactly which areas of the human genome retain segments of Neanderthal DNA.
