[In Depth] Triumph for gravitational wave hunt More than a billion years ago, two black holesthe gravitational ghosts of gigantic starsspiraled together and collided in space. Ripples in spacetime swept through the universe. Five months ago, they washed past Earth, and physicists detected gravitationa

[In Depth] Neandertal genes linked to modern diseases When modern humans met and mated with Neandertals about 50,000 years ago, they picked up genes that are shaping health and well-being today. In a new study on p. 737, researchers use a powerful new method for scanning the electronic health records of 28,0

[Perspective] A new diet for methane oxidizers In anoxic marine sediments, consortia of methane-consuming archaea and sulfate-reducing bacteria oxidize methane. Together, they thereby control methane discharge in a metabolism of global importance. During this cooperative interspecies interaction, know

[Perspective] A unifying model of epigenetic regulation Expression of the genome is controlled by an intricate web of proteins, chemical modifications, and RNA that together organize genomic DNA into chromatin. Molecular studies of the various forms and levels of chromatin organization are advancing rapidly, r

[Perspective] Modulating pulmonary inflammation The human respiratory tract transports millions of liters of gases throughout life. Because the conducting airways are exposed to countless microbes, particles, and toxicants, the tract has evolved an immune system that protects lung structure and functio
