DNA Traces Illegal Ivory Shipments Back to Major CartelsNews
The international trade in elephant ivory has been illegal since 1989, yet African elephant numbers continue to decline. A study reports that DNA test results of ivory seizures made by law enforcement have linked multiple ivory shipments to the same network of dealers operating out of a handful of African ports.READ MORE
Researchers led by St. Jude Children's Research Hospital scientists have identified another way the process that causes oil to form droplets in water may contribute to solid tumors, such as prostate and breast cancer.READ MORE
When people take MDMA, the drug popularly known as ecstasy, a rush of serotonin, dopamine, and oxytocin makes people more interested than they would normally be in connecting and sharing with other people. Now, researchers have made the surprising discovery that a species of octopus considered to be asocial responds to MDMA in the same way.
Over the past several years, CRISPR-Cas9 has moved beyond the lab bench and into the public zeitgeist. Now, scientists from the Salk Institute are reporting for the first time the detailed molecular structure of CRISPR-Cas13d, a promising enzyme for emerging RNA-editing technology.READ MORE
In treating inflammatory bowel disease (IBD), physicians can have a hard time telling which newly diagnosed patients have a high risk of severe inflammation or what therapies will be most effective. Now researchers report finding an epigenetic signature in patient cells that appears to predict inflammation risk in a serious type of IBD called Crohn’s disease.
An antioxidant in green tea called epigallocatechin gallate has been found to have a surprising use: sneaking therapeutic RNAs into cells.READ MORE
Study could lead to new treatments for advanced epithelial cancers such as lung and prostate cancers.READ MORE
Scientists from the UNC School of Medicine discovered that the anti-inflammatory protein NLRP12 normally helps protect mice against obesity and insulin resistance when they are fed a high-fat diet. The researchers also reported that the NLRP12 gene is underactive in people who are obese, making it a potential therapeutic target for treating obesity and diabetes.READ MORE
The spatial and temporal dynamics of proteins or organelles plays a crucial role in controlling various cellular processes and in development of diseases. However, acute control of activity at distinct locations within a cell cannot be achieved. A new chemo-optogenetic method enables tunable, reversible, and rapid control of activity at multiple subcellular compartments within a living cell.
Researchers from the Department of Biochemistry and Molecular Biology at the UAB and from the United Kingdom, for the first time describe the mechanism used by cells to optimise protein production in stressful situations through the altering of tRNA abundance.
