Social Neuroscience: More Friends, More Problems…More Gray Matter?

The social brain hypothesis generically posits that increasing social group size relates is associated with an increase in neocortex size. A new study identifies, within a species, the specific neural circuit that may confer the primate ability to manage social relationships as they increase in number.

Recall that in biological experiments only relatively short segments of the DNA can be investigated. To investigate the structure of a long DNA molecule, the DNA is broken into smaller fragments that can be studied more easily by biological experiments. For instance, physical mapping aims at ordering these fragments based on overlap information obtained from hybridization experiments with a set...

More Equienergetic Signed Graphs

The energy of signed graph is the sum of the absolute values of the eigenvalues of its adjacency matrix. Two signed graphs are said to be equienergetic if they have same energy. In the literature the construction of equienergetic signed graphs are reported. In this paper we obtain the characteristic polynomial and energy of the join of two signed graphs and thereby we give another construction ...
