Many children who grow up in poverty have higher levels of behavioral problems and lower IQ scores than children who grow up in middle class families. However, some children from poor family backgrounds are resilient -- that is, they behave better and score higher on intelligence tests than might be expected given the level of social and economic deprivation they have experienced.
Researchers have identified several protective factors that promote childrens resilience, including a childs easy, sociable personality, a mothers warmth toward her child, and a stimulating home environment. However, we still dont know to what extent these protective factors and childrens resilience might be associated with a common genetic factor. It may be that the genes involved in promoting the protective factor are the same genes that promote childs positive development under conditions of poverty. For instance, the genes that contribute to a mothers emotional warmth could be the same genes she passes onto her child, which promote the childs resilience. In this study, we tried to determine the degree to which genetic versus social-environmental influences explain childrens resilience against poverty.
We interviewed 1,116 mothers and their 5-year-old twins in the United Kingdom to assess the familys level of socioeconomic hardship, the twins antisocial behavior at home, and their IQ. We also received reports from teachers about the twins behavior at school.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
