Exposure to diverse career paths can help fill labor market 'skills gap'  

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, interests and personality. As the father of three children, including a daughter soon to enter high school, he wants to ensure they are equipped with the knowledge and skills

Measuring the tRNA world  

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 can be used to quantify tRNAs in any organism and will help improve our understanding of tRNA regulation in health and disease.

Antarctica's northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared to 31 previous summers of dramatically lower melt, a new study found. Using satellite observations that detect meltwater on top of the ice and within near-surface snow, the researchers found the most widespread melt of any season. Surface meltwater ponding is potentially dangerous to ice shelves because when these lakes drain, the ice fractures and may trigger ice-shelf break-up.
