• 19:36 New tool for analyzing solar-cell materials

  Read the story at ScienceDaily
  An online tool called "Impurities to Efficiency" (known as I2E) allows companies or researchers exploring alternative manufacturing strategies to plug in descriptions of their planned materials and processing steps. After about one minute of simulation, I2E gives an indication of exactly how efficient the resulting solar cell would be in converting sunlight to electricity.

• 16:01 An electronic green thumb

  Read the story at ScienceDaily
  If sensors are supposed to communicate with each other to compare the measured data and to secure them, then, in the future, a network of distributed sensor nodes will aid in that: the network ensures problem-free communication between the sensors. For example, they can be used to reliably monitor the watering of plants.

• 16:01 Neanderthal demise due to many influences, including cultural changes

  Read the story at ScienceDaily
  Although many anthropologists believe that modern humans ancestors "wiped out" Neanderthals, it's more likely that Neanderthals were integrated into the human gene pool thousands of years ago during the Upper Pleistocene era as cultural and climatic forces brought the two groups together.

• 16:00 The dark path to antisocial personality disorder

  Read the story at ScienceDaily
  With no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial. Antisocial personality disorder is defined as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood," according to a standard definition. But, until now, no one has studied the dimensional structure associated with the DSM antisocial personality disorder criteria.

• 16:00 Why the middle finger has such a slow connection

  Read the story at ScienceDaily
  Each part of the body has its own nerve cell area in the brain -- we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by neuroscientists through reaction time measurements combined with learning experiments and "computational modeling." They have been able to demonstrate that inhibitory influences of neighboring "finger nerve cells" affect the reaction time of a finger.
