Biologists from the Plant Physiology Laboratory at the University of Guam and neuroscientists from the Experimental Medicine Program at The University of British Columbia have published an update on the reputed environmental toxins that have been suspected of being involved in mammal neurodegeneration.
A signaling protein thought to be able to treat liver damage in paracetamol toxicity could actually worsen it. Instead, Singapore scientists discovered, blocking its effects could be the way forward.
New research published today indicates that BAT's modern oral (MO) products in the form of tobacco-free nicotine pouches have a toxicant profile that is comparable to nicotine replacement therapies (NRTs) and much lower than traditional oral snus, a category of products that, when used as the sole nicotine product is already established as a reduced risk product compared with cigarettes.
Glyphosate is an herbicide commonly used in forestry operations throughout British Columbia, Canada. Researchers investigated how the chemical may affect the reproductive health of prickly wild rose, a perennial plant found beneath the forest canopy. The new study, by the open access publisher Frontiers, found that pollen viability decreased by an average of 66 percent compared to untreated plants a year after the herbicide was initially applied, with traces of glyphosate persisting for at least two years.
The University of Ottawa has been awarded four new Canada Research Chairs (CRC) that will strengthen its expertise in artificial intelligence, health and law, plus the renewal of two CRCs that will conduct leading-edge research in quantum communications and photonics.
Just two weeks of citalopram exposure caused changes in crayfish behavior, with the potential to disrupt stream ecosystem processes like nutrient cycling, oxygen levels, and algal growth.
Expose crayfish to antidepressants, and they become more outgoing -- but that might not be such a positive thing for these freshwater crustaceans, according to a new study.
Makeup wearers may be absorbing and ingesting potentially toxic per- and polyfluoroalkyl substances (PFAS), according to a new study. The researchers found high fluorine levels--indicating probable presence of PFAS--in about half of makeup tested. Some products underwent further analysis and were all confirmed to contain at least four PFAS of concern. Most products had no PFAS listed on the label.
Researchers analyzed the epigenetics--molecular factors and processes that determine whether genes are turned on or off--of a group of Poecilia mexicana fish that live in springs naturally high in hydrogen sulfide, which is normally toxic to most organisms. Even after raising samples of fish in freshwater, researchers found that grandchildren of sulfidic-adapted fish had more epigenetic marks in common with their wild, toxic-water-living grandparents than Poecilia mexicana that had always lived in freshwater.
Researchers at the University of São Paulo discover that the fungus Fusarium verticillioides uses volatile compounds to manipulate insects and plants, promoting its own dissemination.
