Tracing the start of COVID-19 in GA

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

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Blog editor shift

This is partly a temporary good-bye and partly an introduction to Wayne Drash.

Wayne will be filling in for Quinn Eastman, who has been the main editor of Lab Land. Wayne is a capable writer. He spent 24 years at CNN, most recently within its health unit. He won an Emmy with Sanjay Gupta for a documentary about the separation surgery of two boys conjoined at the head.

Wayne plans to continue writing about biomedical research at Emory, both COVID-19-related and not. He and Quinn are particularly interested in the efforts of Emory physicians and immunologists to develop a convalescent plasma bank and serology testing, as well as the continued progress of the DRIVE antiviral. It has been inspiring to see the Emory research community rally against COVID-19, despite huge challenges.

Charlotte Observer highlights Lab Land

Thanks to Amber Veverka for featuring Lab Land as part of the Charlotte Observer’s regular look at science-oriented blogs. I reproduce my responses here to add some links.

Describe the range of health science research you are covering on Lab Land – and a little bit about your intended audience.

Any intriguing idea emerging from basic or clinical biomedical research happening at Emory. The blog is aimed at people who are somewhat familiar with biological concepts, like graduate students, postdocs or science journalists.

What are some of the most exciting advances you’ve recently written about?

Here are a few!

*Neuroscientists found that a mouse can pass on a learned sensitivity to a smell to its offspring

*Cardiologists discovered that heart muscle cells in mice grow in a dramatic spurt after birth, with implications for the treatment of congenital heart defects.

*Some peoples’ brains produce something that acts like a sleeping pill, giving them hypersomnia. It’s not clear what this mysterious brain chemical is yet.

*Less invasive epilepsy surgery involving lasers; seizure control with fewer cognitive side effects

*Biomedical engineers are developing ways to prevent stem cells from being washed out of the heart Read more
