Scientists confirm theory regarding the origins of the sucking disc of remora fish Posted: 06 Jun 2013 04:10 PM PDT Remora fish, with a sucking disc on their heads, have been the stuff of legend. They often attach themselves to boat hulls and were once thought to purposely slow the boat down. While that is a misunderstanding, something else not well understood was the origins of the fish's sucking disc. Scientists, however, have solved that mystery proving that the disc is actually a greatly modified dorsal fin.

Astronomers gear up to discover Earth-like planets Posted: 06 Jun 2013 04:08 PM PDT Dust clouds around stars are thought to hide many undiscovered planets with conditions suitable for life, but observations have been hampered by the fact that only the brightest such clouds can be detected with current technology. Astronomers are developing a technique to detect faint dust clouds, many of which might hide Earth-like planets.

By trying it all, predatory sea slug learns what not to eat Posted: 06 Jun 2013 04:08 PM PDT Researchers found that a type of predatory sea slug with a simple nervous system has more complex cognitive abilities than previously thought, allowing it to learn the warning cues of dangerous prey and avoid them in the future.

How similar are the gestures of apes and human infants? More than you might suspect Posted: 06 Jun 2013 04:08 PM PDT A new study used naturalistic video data for the first time to compare gestures in a female chimpanzee, bonobo and human infant.

Spooky action put to order: Different types of 'entanglement' classified Posted: 06 Jun 2013 12:47 PM PDT A property known as "entanglement" is a fundamental characteristic of quantum mechanics. Physicists and mathematicians have now shown how different forms of this phenomenon can be efficiently and systematically classified into categories. The method should help to fully exploit the potential of novel quantum technologies.

Gannets don't eat off each other's plates Posted: 06 Jun 2013 12:47 PM PDT Colonies of gannets maintain vast exclusive fishing ranges despite doing nothing to defend their territory from rival colonies, scientists have discovered.

Quantum teleportation between atomic systems over long distances Posted: 06 Jun 2013 11:08 AM PDT Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation -- not just one or a few times, but successfully every single time.

Stars don't obliterate their planets (very often) Posted: 06 Jun 2013 10:47 AM PDT Stars have an alluring pull on planets, especially those in a class called hot Jupiters, which are gas giants that form farther from their stars before migrating inward and heating up. Now, a new study using data from NASA's Kepler Space Telescope shows that hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars. Instead, the planets remain in fairly stable orbits for billions of years, until the day comes when they may ultimately get eaten.

New DNA test on roo poo identifies species Posted: 06 Jun 2013 07:13 AM PDT Researchers have developed a simple and cost-effective DNA test to identify kangaroo species from their droppings which will boost the ability to manage and conserve kangaroo populations.

Living fossils? Actually, sturgeon fish are evolutionary speedsters Posted: 06 Jun 2013 07:13 AM PDT Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years. But a new study reveals that in at least one measure of evolutionary change -- changes in body size over time -- sturgeon have been one of the fastest-evolving fish on the planet.
