Not only does it make you funnier, more attractive and a better dancer but it also tastier to insects in the family Culicidae:
The tents used a complex system of tubing to direct the volunteers' body odour into boxes in such a way that the mosquitoes could choose which scent to go after. Half the volunteers - all men between 20 and 43 - were given one litre of 3% beer to drink, and the other half were given a litre of water. Then the researchers unleashed the lab-bred mosquitoes. The experiment was conducted four times: before beer, after beer, before water and after water. The after-beer group drew 47% of the mosquitoes, compared to the 35% for the before-beer group.
No word on whether the beer selected makes a difference, whether a 9% beer would have three times the effect. The study has a serious purpose in the control of the spread of malaria through understanding the factors that contribute to the mosquito hosts biting. But it's still good to know that beer in fact does make us tastier.
