If you're about to invest in a lot of DVDs for your new baby, here's a way to save some money; they won't help.  Of course, there is some correlation/causation data to classical music but it's correlation/causation data because parents who listen to classical music and buy it for their kids tend to be better educated and care about their kids' education, which is reflected in more ways than just music.

Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago. The fan offers compelling evidence that it was formed by melt water that originated in nearby snow and ice deposits and may stand as the most recent period when water flowed on the planet.Gullies are known to be young surface features on Mars. But scientists studying the planet have struggled with locating gullies they can conclusively date. In a paper that appears on the cover of the March issue of Geology, the Brown geologists were able to date the gully system and hypothesize what water was doing there.

Want your kids to eat more carrots?   Call them 'X-ray carrots', says a new Cornell University study which shows that giving vegetables catchy new names – like X-Ray Vision Carrots and Tomato Bursts – left preschoolers asking for more.When 186 four-year olds were given carrots called "X-ray Vision Carrots" ate nearly twice as much as they did on the lunch days when they were simply labeled as "carrots." The Robert Wood Johnson-funded study also showed the influence of these names might persist. Children continued to eat about 50% more carrots even on the days when they were no longer labeled. The new findings were presented on Monday at the annual meeting of the School Nutrition Association in Washington DC. 

Young men who have served in the British Armed Forces are up to three times more likely to take their own lives than their civilian counterparts, research published tomorrow (March 3) has found.Researchers at The University of Manchester's Centre for Suicide Prevention linked UK military discharge data between 1996 and 2005 with details of suicides collected by the National Confidential Inquiry into Suicides and Homicides.

Sometimes known as "nature's origami", the way that proteins fold is vital to ensuring they function correctly. But researchers at the University of Leeds have discovered this is a 'hit and miss' process, with proteins potentially folding wrongly many times before they form the correct structure for their intended purpose. The body's proteins carry out numerous functions and play a crucial role in the growth, repair and workings of cells. Sheena Radford, Professor of Structural Molecular Biology at the University of Leeds, says: "There's a fine balance between a protein folding into the correct shape so that it can carry out its job efficiently and it folding incorrectly, which can lead to disease. Just one wrong step can tip that balance."

Women can take pride that they are more efficient than men in many ways, including one that is not so great; storing fat.It's a paradox women have discussed for generations – their apparent ability to store fat more efficiently than men, despite eating proportionally fewer calories.   While it has long been suspected that female sex hormones are responsible, a University of New South Wales (UNSW) research review has for the first time drawn a link between one hormone – estrogen – and its impact on fat storage for childbearing.

Did you ever get called impulsive by a teacher?   You're lucky you don't live in Montreal.

Titan's vast dune fields, which may act like weather vanes to determine general wind direction on Saturn's biggest moon, have been mapped by scientists who compiled four years of radar data collected by the Cassini spacecraft. Titan's rippled dunes are generally oriented east-west. Surprisingly, their orientation and characteristics indicate that near the surface, Titan's winds blow toward the east instead of toward the west. This means that Titan's surface winds blow opposite the direction suggested by previous global circulation models of Titan. 

A study in the March 1 issue of  SLEEP suggests the presence of an intrinsic sleep problem specific to attention-deficit/hyperactivity disorder (ADHD) and supports the idea that children with ADHD may be chronically sleep deprived and have abnormal REM sleep. Results show that children with ADHD have a total sleep time that is significantly shorter than that of controls. Children in the ADHD group had an average total sleep time of eight hours, 19 minutes; this was 33 minutes less than the average sleep time of eight hours, 52 minutes, in controls. Children with ADHD also had an average rapid eye movement (REM) sleep time that was significantly reduced by 16 minutes. 

Puny Crayfish may have big claws for show but they can't really use them - their muscles are actually weaker than females with smaller claws.So why does it work?  A group of scientists writing in The Journal of Experimental Biology set out to discover the answer.Slender crayfish are aggressive territorial creatures, explains ecologist Robbie Wilson of the University of Queensland, Australia. When two crayfish catch sight of one another, they size each other up in a ritualistic display, which can quickly escalate from careful tapping of their opponent's chelae (enlarged front claws) to a full-blown fight.  

"Psychedelica" seems the perfect name for a species of fish that is a wild swirl of tan and peach zebra stripes and behaves in ways contrary to its brethren, says University of Washington’s Ted Pietsch, first to describe the new species in the scientific literature and therefore got to select the name.Psychedelica is perhaps even more apt given the cockamamie way the fish swim, some with so little control they look intoxicated and should be cited for DUI.

What use is half a wing?When Charles Darwin unleashed his revolutionary theory of evolution in the mid-1800s, one of the first questions doubters nailed him with went something like ; you have the four limbs of a reptile and then a beautiful flying bird. What are the intermediary steps? Darwin, what use is half a wing?There wasn’t much the esteemed naturalist could say with the data he had available and, during the next 150 years, scientists were largely divided into two theoretical camps regarding the evolution of flight.
