Animals warn of human health hazards in new 'Canary Database'
...man animals could be more sensitive to many of the agents
that are potential biological or chemical weapons and could therefore serve as "sentinels" for a terrorist attack. At the same time, the public health system has been slow to use animal sentinel data to detect and reduce human environmental health ha...

...discovery may eventually lead to new antimicrobial agents
to halt bacterial growth which would be an entirely new system to shut bacteria down, according to the scientists. "This has potential implications for new antibiotics," said Low. "If bacteria can do this, then maybe we can do it." Doctoral student ...

are produced yearly by countries around the world. Registered as priority pollutants by the EPA, they are toxic to aquatic life. They produce immediate toxic effects to the nervous system, and some reports have implicated them as possible endocrine d...
Unexpected features of anthrax toxin may lead to new types of therapies
...the lead author of the PNAS paper. Pharmaceutical agents
that are designed to block the acid-dependent route of toxin entry may fail to block the neutral pH-dependent pathway, the researchers say. In addition, the researchers made a finding that could potentially lead to a new approach for blocking toxin ...

Animal model of Parkinson's disease reveals striking sensitivity to common environmental toxins
...tion leads to an increased sensitivity to chemical agents
that cause oxidative damage. Min and his colleagues found that loss of function of one form of fly DJ-1, DJ-1b, caused a compensatory boost in expression of the other form of the gene, DJ-1a. These flies, lacking DJ-1 function but having increased D...
