A team of zoologists and microbiologists from NUI Galway have published a new study showing that common house spiders carry bacteria susceptible to infect people, with the Noble False Widow spiders also carrying harmful strains resistant to common antibiotic treatments.
Cleaning surfaces with hydrogen peroxide-based disinfectants has the potential to pollute the air and pose a health risk, according to research led by University of Saskatchewan (USask).
Humans are exposed to various environmental or dietary molecules that can attenuate or even increase the effect of therapeutic drugs. Studies on the industrial chemical bisphenol A and the phytoestrogen genistein, for example, have shown drug-exposome interactions. However, interactions between exposures and therapeutic agents have not been systematically investigated to date, conclude chemists Benedikt Warth and Manuel Pristner at the University of Vienna in a review article published in 'Trends in Pharmacological Sciences'.
Plastics in the ocean can release chemicals that cause deformities in sea urchin larvae, new research shows.
Portland State University researchers and their collaborators at the Quinault Indian Nation and Oregon State University found microplastics in Pacific razor clams on Washington's sparsely populated Olympic Coast -- proof, they say, that even in more remote regions, coastal organisms can't escape plastic contamination.
Laboratory tests of talc-based cosmetics products, commissioned by the Environmental Working Group, found asbestos -- a deadly human carcinogen for which there is no safe level of exposure -- in almost 15 percent of samples.
Triclosan, an antimicrobial found in many soaps and other household items, worsens fatty liver disease in mice fed a high-fat diet.
A bird-catching Chinese tarantula bite contains a stinger-like poison that plunges into a molecular target in the electrical signaling system of their prey's nerve cells. New cryo-electron microscopy studies show how this venom traps the voltage sensors of sodium channels in a resting state so they can't be activated. Such research may suggest designs for better drugs for chronic pain.
The African crested rat is the only mammal known to sequester plant toxins for chemical defense. A new study confirmed that the rabbit-sized rodent licks poison from the bark of Acokanthera schimperi, known as the poison arrow tree, into specialized fur. The researchers also discovered an unexpected social life--the rats appear to be monogamous and may even form small family units with their offspring.
In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease, including possibly COVID-19.
