Flies are attracted to glycerol, a chemical in beer produced during fermentation. Understanding more about the genes responsible for taste and smell in flies could help make powerful insect repellents.
Scientists in California think they've figure out why flies like beer. That may sound a bit trivial, but in fact it could lead to new ways of combating plant and animal pests.

She's part of an inter-disciplinary program involving neuroscience and entomology at the University of California, Riverside. She's been studying how flies recognize chemicals, so answering the question of why flies like beer is actually quite relevant to her research.

As the European debt crisis drags on, one question being asked is what will happen to Italy. The new government of Prime Minister Mario Monti is struggling to convince the financial markets that the country has a plan to pay its debts. Among other things, Monti says he will do something about Italy's long tradition of tax evasion, which is considered somewhat of a national sport.
