| Genetic markers help feds enforce seafood regulations Posted: 06 Dec 2011 08:52 AM PST New discoveries in "marine forensics" will allow federal seafood agents to genetically test blue marlin to quickly and accurately determine their ocean of origin. The test is needed to ensure that the blue marlin sold in US seafood markets were not taken from the Atlantic Ocean. Regulation of Atlantic blues reflects overfishing and a troubling drop in population.  |
| New horned dinosaur announced nearly 100 years after discovery Posted: 06 Dec 2011 08:50 AM PST A new species of horned dinosaur was just announced by an international team of scientists, nearly 100 years after the initial discovery of the fossil. The animal, named Spinops sternbergorum, lived approximately 76 million years ago in southern Alberta, Canada. Spinops was a plant-eater that weighed around two tons when alive, a smaller cousin of Triceratops.  |
| Inbreeding in bed bugs: One key to massive increases in infestations Posted: 06 Dec 2011 08:50 AM PST New research on the bed bug's ability to withstand the genetic bottleneck of inbreeding provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally. After mostly disappearing in the US in the 1950s, the common bed bug has reappeared with a vengeance over the past decade.  |
| Sandeels with a full stomach swim for a longer time Posted: 06 Dec 2011 08:42 AM PST Researchers have shed light on the peculiar behavior of the commercially and ecologically valuable sandeel.  |
| Ancient meat-loving predators survived for 35 million years Posted: 06 Dec 2011 07:14 AM PST A species of ancient predator with saw-like teeth, sleek bodies and a voracious appetite for meat survived a major extinction at a time when the distant relatives of mammals ruled the earth.  |
| Posted: 06 Dec 2011 05:27 AM PST Scientists have developed important new insight into the sensitivity of global temperature to changes in Earth's radiation balance over the last half million years.  |
