Bilingual children switch tasks faster than speakers of a single language Posted: 03 Apr 2012 08:20 AM PDT Children who grow up learning to speak two languages are better at switching between tasks than are children who learn to speak only one language, according to a study funded in part by the National Institutes of Health. However, the study also found that bilinguals are slower to acquire vocabulary than are monolinguals, because bilinguals must divide their time between two languages while monolinguals focus on only one.

Arteries under pressure early on: Mice fed a high-fat diet show signs of artery damage after only six weeks Posted: 03 Apr 2012 08:20 AM PDT High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure.

Activity in brain networks related to features of depression Posted: 03 Apr 2012 08:19 AM PDT Depressed individuals with a tendency to ruminate on negative thoughts, i.e. to repeatedly think about particular negative thoughts or memories, show different patterns of brain network activation compared to healthy individuals, report scientists of a new study.

Quantum information motion control is now improved Posted: 03 Apr 2012 08:18 AM PDT Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. This study could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons.

Plants mimic scent of pollinating beetles Posted: 03 Apr 2012 08:18 AM PDT The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist has now demonstrated that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing scents of scarab beetles and thus adapted to the beetles unilaterally. The mutual adaptation between plants and pollinators therefore does not always take place.

Is bioenergy expansion harmful to wildlife? Posted: 03 Apr 2012 08:18 AM PDT Despite the predicted environmental benefits of biofuels, converting land to grow bioenergy crops may harm native wildlife. Researchers have developed a way to study the effects of increased energy crop cultivation on farmland bird populations.

Photoperiodism may slow the range shift of species northwards Posted: 03 Apr 2012 08:16 AM PDT Climate change is predicted to promote species' range shifts and invasions from southern latitudes northwards. However, climate change does not affect the seasonal variation in day length. The length of the day in northern latitudes still depends on the position of the Earth in relation to the Sun. The photoperiodism of species -- in other words, their ability to adapt to seasonal variation in day length and quality of light -- plays an important role when species attempt to expand their distribution range northwards, experts report.

New light shone on photosynthesis Posted: 03 Apr 2012 05:52 AM PDT One of the outstanding questions of the early Earth is how ancient organisms made the transition from anoxygenic (no oxygen produced) to oxygenic photosynthesis. Scientists have now moved closer to solving this conundrum.

What do ADHD and cancer have in common? Variety Posted: 02 Apr 2012 01:28 PM PDT According to new research, attention deficit hyperactivity disorder is more than one disorder. It's an entire family of disorders, much like the multiple subtypes of cancer. The research, which highlights various versions of the disease, each with differing impacts, demonstrates that there is likely not going to be a "one-size-fits-all" approach to treating patients.
