Researchers make bombshell discovery of an entirely new kind of biomolecule

Date Time Researchers make ‘bombshell’ discovery of an entirely new kind of biomolecule A newfound biomolecule, consisting of RNA modified by sugars, could be present in all forms of life and might contribute to autoimmune disease. By Holly Alyssa MacCormick Stanford researchers have discovered a new kind of biomolecule that could play a significant role in the biology of all living things. The novel biomolecule, dubbed glycoRNA, is a small ribbon of ribonucleic acid (RNA) with sugar molecules, called glycans, dangling from it. Up until now, the only kinds of similarly sugar-decorated biomolecules known to science were fats (lipids) and proteins. These glycolipids and glycoproteins appear ubiquitously in and on animal, plant and microbial cells, contributing to a wide range of processes essential for life.

Stanford researchers use AI to empower environmental regulators

Brick kilns have proliferated across Bangladesh to supply the growing economy with construction materials, which makes it really hard for regulators to keep up with new kilns that are constructed, said co-lead author Nina Brooks, a postdoctoral associate at the University of Minnesota s Institute for Social Research and Data Innovation who did the research while a PhD student at Stanford. While previous research has shown the potential to use machine learning and satellite observations for environmental regulation, most studies have focused on wealthy countries with dependable data on industrial locations and activities. To explore the feasibility in developing countries, the Stanford-led research focused on Bangladesh, where government regulators struggle to locate highly pollutive informal brick kilns, let alone enforce rules.

Single-dose COVID-19 vaccine triggers antibody response in mice

ACS Central Science Across the world, health care workers and high-risk groups are beginning to receive COVID-19 vaccines, offering hope for a return to normalcy amidst the pandemic. However, the vaccines authorized for emergency use in the U.S. require two doses to be effective, which can create problems with logistics and compliance. Now, researchers reporting in ACS Central Science have developed a nanoparticle vaccine that elicits a virus-neutralizing antibody response in mice after only a single dose. The primary target for COVID-19 vaccines is the spike protein, which is necessary for SARS-CoV-2’s entry into cells. Both of the vaccines currently authorized in the U.S. are mRNA vaccines that cause human cells to temporarily produce the spike protein, triggering an immune response and antibody production. Peter Kim and colleagues wanted to try a different approach: a vaccine consisting of multiple copies of the spike protein displayed on ferritin nanoparticles. Ferritin is an
