ALMA Finds 'Monster' Starburst Galaxies in the Early Universe: Observatory’s Early Strides Provide Astounding View of Cosmic History
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered starburst galaxies earlier in the Universe’s history than they were previously thought to have existed. These newly discovered galaxies represent what today's most massive galaxies looked like in their energetic, star-forming youth. |

Nanoparticles Loaded with Bee Venom Kill HIV
Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown. The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS. |

Hubble Finds Birth Certificate of Oldest Known Star
A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that's been around for a very long time.The star could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe's calculated age of about 13.8 billion years, an obvious dilemma. |

Vortex Loops Could Untie Knotty Physics Problems
University of Chicago physicists have succeeding in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists. |

Study Finds Energy Use in Cities Has Global Climate Effects
The heat generated by everyday energy consumption in metropolitan areas is significant enough to influence the character of major atmospheric circulation systems, including the jet stream during winter months, and cause continental-scale surface warming in high latitudes. |

Migraine Triggers May Not Be As Strong As You ThinkA new study suggests that triggers for migraine with aura may not be as strong as some people think. The research is published in the January 23, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Auras that occur with migraine include visual disturbances, with symptoms such as flashing lights or wavy lines. |
