# psych: a view around dark personalities, by Morten et al.

<< Egoism, Machiavellianism, narcissism, psychopathy, sadism, spitefulness and others are among the traits of the malevolent side of human personality. As results from a recently published German-Danish research project show, these traits share a common "dark core." People with one of these tendencies are also likely to have one or more of the others. >>

# evol: adaptability by genome duplications (A. kamchatica)

<< "With these results, we have demonstrated on a molecular-genetic level that genome duplications can positively affect the adaptability of organisms," says plant scientist Timothy Paape. The multiple gene copies enable the plant to assume advantageous mutations while keeping an original copy of important genes. >>

# chem: a 'ghost' bond with a partner that isn't there

<< A peculiar type of atom can be induced to form a ‘ghost’ chemical bond with a nonexistent atom, according to new calculations. >>

<< A highly excited atom that includes a loosely bound electron has the weird ability to form 'trilobite' chemical bonds. Such bonds are created by the small attraction between the electron and a second atom in its lowest energy state. The electron is most often found at long distances from its host nucleus, 'reaching out' to the second atom. A visualization of the electron’s likely location in this ultra-long-range bond depicts a series of elongated shells that resemble the segments of an extinct sea animal called a trilobite. >>

<< Through computer simulations, [AA] found that the same effect can be engineered even in the absence of the second atom by exposing the excited atom to a rapid series of electric and magnetic pulses. In the resultant ghost chemical bond, the excited electron appears to reach out to the nonexistent second atom. Such a bond could be formed in a laboratory setting, the authors write. >>

<< The existence of such a ghost chemical bond in which an electron reaches out from one atom to a nonexistent second atom is a consequence of the high level degeneracy. >>

# game: where cooperation is flexible, not fixed

<<
- Assortment on cooperation is a characteristic feature of hunter-gatherer life
- Assortment persists despite substantial migration and residential mixing
- No evidence for stable social types or a preference to live with cooperators
- Individuals respond in kind to the cooperative behavior of their group members

# drugs: how to socialize octopuses (O. bimaculoides)

<< By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or "ecstasy," scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree. >>

<< What our studies suggest is that certain brain chemicals, or neurotransmitters, that send signals between neurons required for these social behaviors are evolutionarily conserved. >> Gul Dolen
