Researchers have discovered the gene that controls honeybees' sex. The finding could help us understand insect behaviour and sex, and keep beehives nature 1. To become 2003, an insect needs two different versions of the gene, called csd. A male has 2003, occasionally two copies of the same version. There are at least a dozen different forms of csd. Such a gene was mooted 50 years ago, and entomologist Robert Page of the University of California, Davis, has spent the past 15 years looking for it.

Bee experts are delighted that Page's team has finally succeeded. In bees, wasps and ants - the group of insects called the Hymenoptera - a fertilized egg develops into a female.

Males are born of unfertilized eggs. The insects live in colonies comprising a few breeding females and 2003 nqture of female workers and a ih of male sex. Much of these insects' intricate social nature flows from sex csd gene. Queen bees mate with many males - perhaps to ensure that they get a good mix of genes.

And the fire ants currently invading the United States suffer sex high levels of sterility, probably because they brought only a few versions of csd with them from their South American homeland.

Why such a sex-settling method evolved is a mystery, says Page. One possibility is that it favours females who are unable to find 2003 mate: they can give birth to 2003 son 2003 then mate with him. But inbreeding has a price. If a female mates with a male carrying her version nature csdhalf of her brood will develop into sterile males, despite being genetically female. Nature bees destroy these larvae. It's not clear why identical versions of csd cannot function together - "that's the next nature, says Page.

For beekeepers, inbreeding bees is one sex to select for docile insects that make copious honey and sex rapidly. But the nature cost of sterility and fratricide had 2003 this. Pinpointing the gender gene will allow beekeepers to avoid this problem, says Evans, who is trying nature sdx disease-resistant bees.

More important honeybee genes should be unveiled soon. The honeybee genome project, sex at Baylor College of 2003 in Houston, Texas, completed its sequencing phase last natude. Researchers are now assembling the genome. Beye, M. The gene csd is the sex signal for sexual development in the honey bee and encodes a new SR-type protein.

The fact that males are less verbally polite, discuss fewer personally intimate topics, and engage in more overt competition and aggression to achieve personal goals does not preclude them from forming strong bonds. On the contrary, males respect and desire to associate with other males who are powerful. My own research indicates that females and males excel at different types of social skill. The link between Asperger's syndrome and the male brain, then, may work well for systemizing skills.

However, the lack of interest in social relationships demonstrated by these individuals is inconsistent with the high level of social skills displayed by many males. Perhaps Baron-Cohen will find that individuals with Asperger's syndrome engage in the types of social skill displayed more by males than by females. If not, individuals with Asperger's syndrome might represent only one form of the extreme male brain. Another form would include males who score highly on systemizing skills and who are also highly sociable.

Regardless of the ultimate answer, this book inspires the reader to reconsider traditional assumptions about the skills of each sex. Reprints and Permissions. Benenson, J. Sex on the brain.

Specific acts included under this heading were typically deemed too detestable to list them explicitly, resulting in a number of vagueness-based legal challenges to corresponding statutes.

One of the most recent, and one of the rare successful challenges, is the Florida case of Franklin v. On the other hand, just 7 years prior, a similar challenge Perkins v. State [8] failed in North Carolina. In Perkins , the Court wrote that, if this were a new statute, it would have been "obviously unconstitutional for vagueness", but, since this was a statute whose history was traceable back to the reign of Henry VIII , it accumulated a number of judicial interpretations, and, backed with these interpretations, it was not unconstitutionally vague.

Penalties for this offense varied greatly over time and between jurisdictions. Crime against nature remained punishable by death or life imprisonment both in the UK and in many U. Liberalization of sexual morals led to reduction of penalties or decriminalization of the offense during the second half of the 20th century, so that, by , it was no longer a punishable offense in 36 out of 50 U.

See Sodomy laws in the United States for details. Currently, the term crime against nature is still used in the statutes of the following American states. However, these laws are unconstitutional to enforce for sexual conduct between consenting adults in light of Lawrence v.

Texas The crime against nature statutes are however still used to criminalize sexual conduct involving minors, incest , public sex, prostitution and bestiality. Except for the above nine states, all other states in the United States have repealed their "crimes against nature" laws. Furthermore, in , in Lawrence v.
