Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that […]

When Patrick Rottinghaus began college, he had no idea what he wanted to do with his career. He started out as an “Open” major while he explored possibilities. Today, he is helping young people eager to find their place in the world by identifying their strengths and connecting them with careers that match their skill-set, […]

Scientists have identified 62 genes that lead to both higher levels of body fat but a lower risk of cardiovascular and metabolic diseases. These genes may help to keep body fat healthy, and open a new avenue for developing drugs that lower the risk of diabetes and heart disease. Source: Genes identified that increase the […]

Heart problems cause disturbed gene activity in the brain’s memory center, from which cognitive deficits arise. Researchers at the DZNE come to this conclusion based on laboratory studies. They consider that they have found a possible cause for the increased risk of dementia in people with heart problems. Source: A weak heart makes a suffering […]

Aridification in the central plains of China during the early Bronze Age did not cause population collapse, a result that highlights the importance of social resilience to climate change. Instead of a collapse amid dry conditions, development of agriculture and increasingly complex human social structures set the stage for a dramatic increase in human population […]

The pandemic has made clear the threat that some viruses pose to people. But viruses can also infect life-sustaining bacteria. A research team has developed a test to determine if bacteria are sick, similar to the one used to test humans for COVID-19. Source: Drive-thru type test to detect viral infections in bacteria

As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work helps scientists better understand the evolution of these viruses, how they acquired the ability to infect humans […]
