A significant portion of people who contract the SARS-CoV-2 virus – some estimates suggest more than 40 percent – suffer chronic effects known as Post Acute Sequelae of COVID-19 (PASC), commonly referred to as long COVID. PASC symptoms include fatigue, brain fog, the loss of taste and smell, shortness of breath, and more.
For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord.
Studies since the start of the pandemic have noted that pigs exposed to the coronavirus don’t show clinical signs of disease nor do they transmit the virus to other animals. Iowa State University scientists have uncovered important clues that shed light on why pigs don’t get sick, and the discovery could lead to better treatments for COVID-19 in humans.

Metabolic differences could explain why some metastatic breast cancer cells rapidly generate tumors after migrating from primary tumors to the brain, while others linger for months or years before forming these secondary tumors, UT Southwestern scientists report in a new study. The findings, published in Cell Metabolism, highlight metabolic vulnerabilities in malignant cells that could eventually lead to new cancer therapies.
Harnessing the power of genomics to find risk factors for major diseases or search for relatives relies on the costly and time-consuming ability to analyze huge numbers of genomes. A team co-led by a Johns Hopkins University computer scientist has leveled the playing field by creating a cloud-based platform that grants genomics researchers easy access to one of the world’s largest genomics databases.
Research led by scientists at the Jonsson Comprehensive Cancer Center (JCCC) at UCLA provides new insights into molecular “crosstalk” in pancreas cancer cells, identifying vulnerabilities that could provide a target for therapeutic drugs already being studied in several cancers.

The lab of Youyang Zhao, PhD, from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago developed a unique nanoparticle to deliver genome editing technology, including CRISPR/Cas9, to endothelial cells, which are cells that line blood vessel walls. This is the first time that vascular endothelial cells could be reached for genome editing, since the usual way to deliver CRISPR/Cas9 – through a virus – does not work for this cell type.
