Critics of global warming will note that if the people behind the Kyoto protocol can't even get basic accounting correct there may be plenty of errors in simulations but science is about convergence over time.  And owning up to little mistakes and fixing them.

An international team has found a critical error in the accounting method used to measure compliance with carbon limits and the flaw, which centers on the measurement of CO2 emissions from the use of bioenergy, could undermine greenhouse gas reduction goals if not addressed.

Sex crimes against pre-teen children are no higher during Halloween than at any other times of the year and diverting law enforcement places people at more risk, according to a study in Sexual Abuse: A Journal of Research and Treatment.  

That's not to say parents shouldn't use caution or supervision but the findings raise questions about the wisdom of law enforcement practices aimed at dealing with a problem that does not appear to exist.

Are women naturally different from men when it comes to detecting emotions?    Biology may play a role, since there are few opportunities for socialization to shape such gender differences, and some  evolutionary psychologists have suggested that females, because of their role as primary caretakers, are wired to quickly and accurately decode or detect distress in preverbal infants or threatening signals from other adults to enhance their chances at survival. 

But women are better than men at distinguishing between emotions, especially fear and disgust, according to a new study published in Neuropsychologia and have a keener sense for processing auditory, visual and audiovisual emotions. 

Lightweight drinkers rejoice, it may be nature that keeps you from pounding shots like Indiana Jones squeeze Marion in "Raiders of the Lost Ark".

Researchers at North Carolina State University have found a genetic 'switch' in fruit flies that plays an important role in making flies more tolerant to alcohol.  If you're reading this site, you will not that doesn't automatically translate to humans but a counterpart human gene contributes to a shift from metabolizing alcohol to the formation of fat in heavy drinkers. This shift can lead to fatty liver syndrome – a precursor to cirrhosis.

It takes two to reproductively tango for humans but even when plants  (or animals) can self-fertilize their offspring have longer lives when a mate is involved in the process, according to over 100 mini-evolution experiments involving nematode worms (Caenorhabditis elegans) at the University of Oregon. Going it alone increases susceptibility to genetic mutations and reduces that adaptability to changing environments, says their report in Nature.

By studying the Y chromosome from human dental remains from the Canary Islands, researchers have determined the origin and evolution of paternal lineages from the pre-Hispanic era to the present day. To date, only mitochondrial DNA had been studied, which merely reflects the evolution of maternal lineages, but a team of Spanish and Portuguese researchers carried out molecular genetic analysis of the Y chromosome (transmitted only by males) of the aboriginal population of the Canary Islands to determine their origin and the extent to which they have survived in the current population.

The results suggest a North African origin for these paternal lineages which, unlike maternal lineages, have declined to the point of being practically replaced today by European lineages.
