Swedish researchers at Chalmers University of Technology and the University of Gothenburg have developed an AI method that improves the identification of toxic chemicals—based solely on knowledge of the molecular structure......»»
Tire toxicity faces fresh scrutiny after salmon die-offs
For decades, concerns about automobile pollution have focused on what comes out of the tailpipe. Now, researchers and regulators say, we need to pay more attention to toxic emissions from tires as vehicles roll down the road......»»
Activity in a room stirs up nanoparticles left over from consumer sprays, study shows
Common household products containing nanoparticles—grains of engineered material so miniscule they are invisible to the eye—could be contributing to a new form of indoor air pollution, according to a Rutgers University study......»»
Clumps of an otherwise non-toxic molecule inhibit strep"s DNA-cleaving enzymes, researchers discover
An entirely new approach to inhibiting DNA-cleaving enzymes works through the aggregation of an otherwise non-toxic molecule. This Kobe University discovery may lead to a much-needed method for curbing Streptococcus growth......»»
Researchers reveal water-assisted oxidative redispersion of metal nanoparticles
Oxidative redispersion at elevated temperatures has long been utilized in heterogeneous catalysis for the regeneration of sintered metal catalysts and the synthesis of metal single atom and cluster catalysts. These redispersion processes require a co.....»»
