Toxicology is the study of harmful interactions between chemical, physical, or biological agents and biological systems.
With the introduction of novel caffeinated beverages in the US market over the past several years, including energy drinks, caffeinated waters, and greater array of cold brew and specialty coffees, an updated understanding of caffeine consumption from beverages is warranted.
AZoLifeSciences speaks to Dr. Catia Costa about her latest research that showed how class A drug use can be determined from a single fingerprint.
The human skin is essentially an organ, a fact that that is easy to forget. It is also the largest organ and is continuously exposed, charged with keeping the human inner biology safe from the threats of the outside world.
Bisphenol F chemical (found in plastics) may cause changes in a gene that is crucial for neurological development. Researchers from the Swedish universities of Uppsala and Karlstad made this discovery.
A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.
Microplastics--small plastic pieces less than 5 millimeters in length--are ubiquitous in the environment, and they can have significant effects on wildlife.
A major research project to shape regulation and policy on chemical safety without the use of animal testing has been launched with the aid of €19.3M funding from the European Commission.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds.
A new study finds that California's commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.
A new study exploring the impact of repeated sleep loss during a simulated working week has found that consuming caffeinated coffee during the day helps to minimize reductions in attention and cognitive function, compared to decaffeinated coffee.
A recent Point of Reference article, "The meat of the matter: Environmental dissemination of beef cattle agrochemicals," published in Environmental Toxicology and Chemistry, points at synthetic chemical cocktails being emitted from cattle feed yards into the environment and how they can impact our ecosystem and our health.
Exposure to the widely used weed-killer glyphosate makes genetic changes to rats that can be linked to increased disease in their grandchildren and great-grandchildren, a new study has found.
According to scientific estimations, humans are exposed to at least 10,000 to 100,000 environmental and exogenous compounds in an individual lifetime, which are mainly absorbed through our dietary.
Jacqueline Kimmey speaks to AZoLifeSciences about her research into bacterial pneumonia and the genes that drive its spread from the lungs into the blood.
A University of Massachusetts Amherst environmental health scientist has used an unprecedented objective approach to identify which molecular mechanisms in mammals are the most sensitive to chemical exposures.
With a nearly $2.6 million grant from the National Institutes of Health, Michigan State University researchers are using nanoscopic particles to turn the body's own cells into weapons that cancer won't see coming.
By far the most important process in cell development is how cells divide and then enlarge in order to multiply. A research team headed by Freiburg medical scientist Prof. Dr. Robert Grosse has now discovered that bundled fibers of actin within a cell nucleus play an important part in how they enlarge after division.
Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler.
Marcel Leist, Professor of In-Vitro Toxicology and Biomedicine at the University of Konstanz, and Thomas Hartung, Professor of Environmental Health Sciences at the University of Konstanz and Doerenkamp-Zbinden Chair of Evidence-Based Toxicology at Johns Hopkins Bloomberg School of Public Health in Baltimore, have been awarded the Ursula M. Händel Animal Welfare Prize 2020 of the German Research Foundation.
