Snails And Humans Use Same Genes To Tell Right From Left:
Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.
Selflessness -- Core Of All Major World Religions -- Has Neuropsychological Connection:
All spiritual experiences are based in the brain. That statement is truer than ever before, according to a University of Missouri neuropsychologist. An MU study has data to support a neuropsychological model that proposes spiritual experiences associated with selflessness are related to decreased activity in the right parietal lobe of the brain.
Shame On Us: Shaming Some Kids Makes Them More Aggressive:
Aren't you ashamed of yourself? All these years, you've been trying to build up your child's self-esteem, and now a growing body of research suggests you may be making a big mistake. A study published in the December issue of Child Development finds that early adolescents with high self-esteem are more likely to react aggressively when they feel ashamed than their peers with lower levels of self-esteem.
Length Of Root Hairs On Plants Made To Grow Longer: Potential Broad Implications For Agriculture:
In the face of climate change, being able to increase crop yields by enabling plants to take up nutrients and water more efficiently becomes increasingly important, as fertiliser and water supplies incur significant energy and environmental costs.
Nitrogen Emissions In Dairy Pastures Peak In The Springtime:
The nitrogen emissions from boreal dairy pastures vary depending on the time of year and ley rotation. The emissions peak in spring, when the nitrates accumulated in the soil over the previous summer and winter leach with the melting snow.
Science's Breakthrough Of The Year: Cellular Reprogramming:
In its annual list of the year's top ten scientific breakthroughs, the journal Science has given top honors to research that produced "made-to-order" cell lines by reprogramming cells from ill patients. These cell lines, and the techniques for producing them, offer long-sought tools for understanding -- and hopefully someday curing -- difficult-to-study diseases such as Parkinson's disease and type 1 diabetes.
Caffeine Has Greater Effect On Men, And Starts Only Ten Minutes After Consumption:
A study headed by researchers from the University of Barcelona (UB) shows that caffeine has a greater effect on men than women, and that these effects start just 10 minutes after it is drunk. In addition, contrary to what was previously thought, it has also been shown that decaffeinated coffee also produces an increased state of alertness.
