Washington State University researchers have found that a rat exposed to a popular herbicide while in the womb showed few apparent health effects, but the grand-offspring of that rat did have more disease, as did a great-grand offspring third generation.
In 2003, Northern California's Yurok Tribe initiated efforts to reintroduce California condors on their lands. While wild condors have not existed in the region for more than a hundred years, a new study from The Condor: Ornithological Applications suggests that hunters transitioning from lead to non-lead ammunition may allow these apex scavengers to succeed there once again.
Researchers at Houston Methodist have solved a 100-year-old mystery, providing them a possible key to unlock a pathway for treating diseases caused by flesh-eating bacteria. Muthiah Kumaraswami and his team at Houston Methodist Research Institute found a critical target on which to focus for developing a potential Group A Streptococcus vaccine or antibiotic to fight it. By manipulating this target, they hope to either reduce the severity of these infections or clear them up faster.
Just under 60 percent of the German population view undesirable substances in food as a high or very high health risk. The most well-known of these substances, which are scientifically denoted as contaminants, are mercury compounds and dioxins. In contrast, only around 13 percent of respondents have heard of the natural contaminants pyrrolizidine alkaloids (PAs) in honey or tea - and only roughly one in three of those who have heard of PAs believe these substances pose a significant health risk.
Researchers conducting a study of newborns experiencing symptoms of drug withdrawal knew the infants' mothers would test positive for substance use. But in the course of their study they had another, surprising finding: They discovered that 1 in 4 women enrolled in the 'drug-free' comparison group, whose infants were not diagnosed with neonatal abstinence syndrome, also tested positive for illicit drug use.
New research to be presented during the American Academy of Pediatrics 2017 National Conference and Exhibition in Chicago suggests an urgent need for safer children's pain medications, with the number of hospitalized infants, children and teens who experienced adverse reactions to opioid painkillers increasing by more than half between 2003 and 2012.
Use of MDMA or 'Molly' is common in the electronic dance music scene, but research is showing that many Molly users are using other drugs unknowingly.
Chemicals that could potentially cause asthma through an immune reaction could be better identified with human cell- and computer-based test methods, according to a new research paper co-authored by the Physicians Committee's Kristie Sullivan, M.P.H., in Applied In Vitro Toxicology.
Sixteen years after the collapse of the World Trade Center towers sent a 'cloud' of toxic debris across Lower Manhattan, children living nearby who likely breathed in the ash and fumes are showing early signs of risk for future heart disease.
Scientists at the Institut Pasteur, CNRS and Inserm, together with a team from Switzerland, have shown that the bacterial pathogen Legionella pneumophila has developed a specific strategy to target the host cell mitochondria, the organelles in charge of cellular bioenergetics. This work provides precious information on how a pathogen manipulates the cellular metabolism to replicate intracellularly, and proposes a new concept of protection of host cells from Legionella-induced mitochondrial changes in order to fight infection.
