Fish devastated by sex-changing chemicals in municipal wastewater

While most people understand the dangers of flushing toxic chemicals into the ecosystem through municipal sewer systems, one potentially devastating threat to wild fish populations comes from an unlikely source: estrogen.After an exhaustive seven-year research effort, Canadian biologists found that miniscule amounts of estrogen present in municipal wastewater discharges can decimate wild fish populations living downstream.

3. Similar brain chemicals influence aggression in fruit flies and humans
   04-22-2007 · EurekAlert!
   Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in animals and humans. Another brain chemical signal, neuropeptide Y (aka neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality in mice. A new study at The Neurosciences Institute (San Diego) shows that these two chemicals also regulate aggression in the fruit fly, Drosophila melanogaster.

4. How 'IAP antagonist' chemicals kill tumors
   11-15-2007 · EurekAlert!
   Chemical compounds specially designed to neutralize proteins that would otherwise allow tumor cells to cheat death have been recognized for some time by scientists as a promising new avenue for cancer therapy. Now, two studies in the Nov. 16, 2007 issue of the journal Cell, a publication of Cell Press, provide insight into just how these antagonists of the anti-death -- so-called Inhibitor-of-Apoptosis (IAP) -- proteins work to fight tumors.

   03-31-2007 · EurekAlert!
   Cultured fish cell lines and organs such as gills, heart, liver and intestines are being used to investigate the effects of toxins on fish such as freshwater trout and carp in a move to cut down the number of experiments carried out on live fish. Fish Biologists will be presenting new culture methods to help replace the use of live fish for safety testing of chemicals in line with a European Commission directive to replace the use of animals in ecotoxicology.

   The latest Taking Stock report from the Commission for Environmental Cooperation reveals a continued decline in releases of toxic chemicals to the environment -- 15 percent for the US and Canada from 1998 to 2004 -- driven by a group of industrial facilities that are the largest generators of emissions.The report also, however, reveals a substantial increase in chemical releases and transfers by a much larger group of industrial facilities that report lower emission volumes.

    08-21-2007 · EurekAlert!
    Bitter taste can ruin a cup of coffee. Now, chemists in Germany and the United States say they have identified the chemicals that appear to be largely responsible for java's bitterness, a finding that could one day lead to a better tasting brew. Their study, one of the most detailed chemical analyses of coffee bitterness to date, will be presented in August at the American Chemical Society national meeting in Boston.
