| Mathematicians show how shallow water may help explain tsunami power Posted: 18 Sep 2012 03:57 PM PDT While wave watching is a favorite pastime of beach-goers, few notice what is happening in the shallowest water. A closer look by two applied mathematicians has led to the discovery of interacting X- and Y-shaped ocean waves that may help explain why some tsunamis are able to wreak so much havoc. |
| Jesus's wife? Scholar announces existence of a new early Christian gospel from Egypt Posted: 18 Sep 2012 01:36 PM PDT Four words on a previously unknown papyrus fragment provide the first evidence that some early Christians believed Jesus had been married, Harvard Professor Karen King told the 10th International Congress of Coptic Studies today. |
| How life arose on Earth: Researchers brew up organics on ice Posted: 18 Sep 2012 01:22 PM PDT Would you like icy organics with that? Maybe not in your coffee, but researchers at NASA's Jet Propulsion Laboratory are creating concoctions of organics, or carbon-bearing molecules, on ice in the lab, then zapping them with lasers. Their goal: to better understand how life arose on Earth. |
| Quasars: Mileposts marking the universe's expansion Posted: 18 Sep 2012 08:34 AM PDT Researchers have found a possible way to map the spread and structure of the universe, guided by the light of quasars. The technique, combined with the expected discovery of millions more far-away quasars over the next decade, could yield an unprecedented look back to a time shortly after the Big Bang, when the universe was a fraction the size it is today. |
| Comet may have exploded over Canada 12,900 years ago after all Posted: 18 Sep 2012 08:13 AM PDT New evidence and support for a theory introduced in 2007 suggested a comet may have exploded over Canada 12,900 years ago (the Younger Dryas Boundary), killing off the Clovis people and large animals and sending the earth back into an ice age. It refutes a study in 2009 that failed to replicate the findings of the 2007 study. The key findings in this new study resulted from sampling done at an archaeological site known as Topper. |
| Higher levels of BPA in children and teens significantly associated with obesity Posted: 18 Sep 2012 08:11 AM PDT Researchers have revealed a significant association between obesity and children and adolescents with higher concentrations of urinary bisphenol A (BPA), a synthetic chemical recently banned by the U.S. Food and Drug Administration (FDA) from sippy cups and baby bottles. Still, the chemical continues to be used in aluminum cans, such as those containing soda. |
| Crews uncover massive Roman mosaic in southern Turkey Posted: 18 Sep 2012 05:39 AM PDT An archaeological team has uncovered a massive Roman mosaic in southern Turkey -- a meticulously crafted, 1,600-square-foot work of decorative handiwork built during the region's imperial zenith. It's believed to be the largest mosaic of its type in the region and demonstrates the reach and cultural influence of the Roman Empire in the area in the third and fourth centuries A.D. |
