If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics.
Stephen T. Warren, 1953-2021
Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more
At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia.
Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more
A study published in the May 17, 2010, issue of the journal Pediatrics found that one type of pesticide commonly used on fruits and vegetables may be contributing to attention deficit hyperactivity disorder, or ADHD, in children.
The study measured the levels of pesticide byproducts in the urine of 1,139 children from across the United States. Children with the highest concentration of pesticides in their urine were more likely to have symptoms of ADHD.
Barr says while the study doesnâ€™t prove causality between pesticide exposures and ADHD, it does shed light on how even low level daily exposures to pesticides could potentially impact cognitive health.
â€œIt seems very plausible that low-level daily exposures to pesticides can produce some subtle effects like ADHD or other neurological delays,â€ she says.
Barr notes that additional research is needed to confirm a connection to pesticides and ADHD, but says there are tips for limiting your exposure to commonly used pesticides.
â€œWeâ€™ve done studies here at Emory and also at CDC that have indicated that if you use organic food or if you wash your food properly prior to preparation, you can reduce the levels of these metabolites in your urine.Â Eat as much organic produce as possible, or wash your fruits and vegetables very well and that likely could decrease the chances of your children developing ADHD,â€ says Barr.
