Orientation is a puzzle to neuroscience researchers and ever more puzzling to us.   If you've ever been lost, or even just in a strange place, you know the feeling of mild panic.  But once you get your bearings, that feeling goes away.   

Disorientation is unpleasant but our brain quickly sorts it out.  Some researcher suggests that animals and young children mainly rely on geometric cues (e.g. lengths, distances, angles) to help them get reoriented while adults can also make use of feature cues (e.g. color, texture, landmarks) in the surrounding area.

Your brain has two methods to compile detail and help you regain orientation, a built-in Global Positioning System (GPS).   But the question for psychologists is which method do we use more often?

Many of the battles to desegregate buses, water fountains and colleges were fought in public but some were virtually unknown and are just now getting attention.  

A new University of Georgia study reveals how two men traveled the Deep South, facing hostility and risking violence, to ensure that students received fair and impartial treatment when it came to standardized testing, an important barrier to getting into many universities even then.

To make children happier, we may need to encourage them to develop a strong sense of 'personal worth', according to Dr. Mark Holder, Associate Professor at the University of British Columbia,  Visiting Assistant Professor Dr. Ben Coleman and graduate student Judi Wallace.   Their research says that children who feel that their lives have meaning and value and who develop deep, quality relationships – what they term measures of spirituality – are happier.

But according to their paper in the Journal of Happiness Studies, actual religious practices have little effect on that happiness.

6 newly discovered genes for obesity have a neural effect, according to the international GIANT (Genetic Investigation of Anthropometric Parameters) consortium.

So far, the scientists have analyzed two million DNA variations in 15 genome-wide association studies with a total of more than 32,000 participants and the identified candidate genes were validated in 14 further studies including 59,000 participants.

In addition to the FTO and MC4R genes already known, it was now possible for six more obesity genes to be identified: TMEM18, KCTD15, GNPDA2, SH2B1, MTCH2, and NEGR1.

Nanotechnology exploits the properties of materials on a nanometric scale, (a nanometer is one millionth of a millimeter). The ultimate limit for such miniaturization is the development of devices formed by atomic structures created artificially to fulfil a determined purpose. 

The tools that permit the visualization and manipulation of atoms are called proximity microscopes. This includes the Scanning Tunneling Microscope (STM), whose development in 1986 earned G. Binning and H. Rohrer the Novel prize for physics, and more recently the Atomic Force Microscope (AFM).
