In-sync brain waves hold memory of objects just seen

Posted: 02 Nov 2012 05:51 PM PDT

The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study suggests. The more in-sync such electrical signals of neurons were in two key hubs of the circuit, the more those cells held the short-term memory of a just-seen object. The work demonstrates, for the first time, that there is information about short term memories reflected in in-sync brainwaves.

Were dinosaurs destined to be big? Testing Cope's rule

Posted: 02 Nov 2012 12:19 PM PDT

In the evolutionary long run, small critters tend to evolve into bigger beasts -- at least according to the idea attributed to paleontologist Edward Cope, now known as Cope's Rule. Using the latest advanced statistical modeling methods, a new test of this rule as it applies dinosaurs shows that Cope was right -- sometimes.

Our solar system is not quite as special as once believed, new research suggests

Posted: 02 Nov 2012 12:19 PM PDT

Some 4.567 billion years ago, our solar system's planets spawned from an expansive disc of gas and dust rotating around the sun. While similar processes are witnessed in younger solar systems throughout the Milky Way, the formative stages of our own solar system were believed to have taken twice as long to occur. Now, new research, suggests otherwise. Indeed, our solar system is not quite as special as once believed.

NASA rover finds clues to changes in Mars' atmosphere

Posted: 02 Nov 2012 12:16 PM PDT

NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere. Learning what happened to the Martian atmosphere will help scientists assess whether the planet ever was habitable.
