Edinburgh, Scotland, UK. Scientists have identified a fundamental difference between female and male cells that control the development of sexual traits. The scientists have named the
phenomenon cell autonomous sex identity (CASI).
Findings from the study,
performed by the Roslin
Institute
at the University of
Edinburgh,
appear in the journal Nature.
It was previously thought that sex chromosomes in birds control whether a testis or ovary forms, with sexual traits then being determ... |

Princeton, NJ, USA. A research team discovered that protein competition over an important enzyme provides a mechanism to integrate different signals that direct early embryonic development. This suggests that signals are combined long before they interact with the organism's DNA, as previously believed, and also may inform new therapeutic strategies.
The mitogen-activated protein kinase (MAPK) enzymes found in all complex organisms, from yeast to humans. MAPK signaling pathways (chemical netw... |

Zurich, Switzerland. Is aggression always the best response to a challenge? Testosterone may not necessarily cause aggression but behavior can drive testosterone secretion.
In an Ultimatum Game, a proposer is given power to decide how a sum of money is divided between him/herself and another player, the decider.
The decider can either accept the offer, and possibly receive less than a fair share, or reject it,in which case both players get nothing. The participants in the game were all women... |

Fairfax, VA, USA. Scientists have taken a further step in our understanding of natural selection by showing that humans, and some of their primate cousins, have a common set of genes which natural selection has often tended to act upon during the past 200,000 years (genetic footprint). This study has also isolated a group of genes that distinguish us from our cousins the great apes.
During evolution, living species have adapted to environmental constraints according to the mechanism of natu... |

Fairfax, VA, USA. One of the world's most widely used pesticides, atrazine, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study. The 75 percent that are chemically castrated are essentially "dead" because of their inability to reproduce in the wild.
Tyrone B. Hayes, professor of integrative biology, says "These male frogs are missing testosterone and all the things that testosteron... |

St. Louis, MO, USA. Many personality and social psychologists have believed the individual is the best judge of her or his own personality. And, it is a very ancient assumption. In the 2nd Century AD, Pausanias , the notable travelogue writer for the ancients, reported that the aphorism know
thyself was inscribed in the Temple of Apollo at Delphi.
Now a psychologist at Washington University in St. Louis has shown that we are not the know-it-alls that we think we are. Simine Vazire, Ph.D., as... |
