Cannabis use can lead to behavioral changes, including reduced social interactions in some individuals. To better understand the phenomenon, Inserm researcher Giovanni Marsicano and his team from NeuroCenter Magendie (Inserm/Université de Bordeaux), in collaboration with Juan Bolaños' team from the University of Salamanca, have identified for the first time in mice the cerebral mechanisms underlying the relationship between cannabis and reduced sociability. Their findings have been published in Nature.
Researchers at Karolinska Institutet in Sweden have developed a new method that can make it easier for public authorities to assess the health risks of hormone-disrupting chemicals in the environment. The study, which is published in Environmental Health Perspectives, shows that women are particularly at risk of decreased levels of thyroid hormones related to PFAS-contaminated drinking water.
A new study from faculty at the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus looks at the relationship between opioid use and driving among older adults. The findings published today in the Journal of the American Board of Family Medicine.
Toxic metallic air pollution nanoparticles are getting inside the crucial, energy-producing structures within the hearts of people living in polluted cities, causing cardiac stress -- a new study confirms.
Some of America's favorite Independence Day fireworks emit lead, copper, and other toxins, a new study suggests. These metals, which are used to give fireworks their vibrant color, also damage human cells and animal lungs.
All per- and polyfluorinated substances (PFAS) should be treated as one class and avoided for nonessential uses, according to a peer-reviewed article published today in Environmental Science & Technology Letters.
Researchers led by Natàlia Carulla find that specific amyloid-beta (Aβ) protein ensembles have the capacity to disrupt the membrane of neurons, causing their death. The results have been published in the journal Nature communications.
Bacterial toxins causing different illnesses share similar molecular mechanisms in a finding that could help treatment development as well as explain the emergence of new diseases.
Fresh insights into why some harmful substances are so efficient at causing cancer could aid the quest for better treatments. New research reveals how chemicals can cause changes in cells to help them dodge the body's immune system and build resistance to cancer drugs. Scientists tracked the impact of a toxic substance - similar to compounds found in tobacco, exhaust and some plants - to better understand how chemicals cause mutations in our cells' DNA.
Scientists have found that man-made mercury pollution has reached the bottom of the deepest part of the ocean -- the Marianas Trench. This has significant implications for how mercury affects the marine environment, and how it may be concentrated in the food chain. The findings, which come from two independent research groups, are presented at the Goldschmidt geochemistry conference.
