Great Salt Lake’s history shows how quickly fresh water can vanish (opens the original)
Read excerpt
USC Dornsife researchers studying the history of Utah’s Great Salt Lake identified two brief, deep-lake phases when the water was much fresher than now. Their analysis of core samples spanning the past 240,000 years shows that the most recent freshwater phase, which formed Lake Bonneville, lasted longer and was fresher than the earlier Little Valley lake phase. The researchers found that both lakes shrank and became salty as the regional climate warmed and dried, offering possible insights into
Evolution may explain why some develop more severe COVID-19 (opens the original)
Read excerpt
Researchers found that four immune system genes bear signatures of thousands of years of human evolution. The study identified rare variants in a particular gene that were associated with severe COVID-19 and with prior organ transplants, which are linked to greater risk of severe COVID-19. Revealing immune system genes shaped by ancient infectious diseases could eventually point to new strategies for disease prevention and treatment. Every time a virus invades a person, it collides with thousand

Read excerpt

But Steve Ross, a historian at the USC Dornsife College of Letters, Arts and Sciences, documents a darker reality: Antisemitism and racism increased after the war, and the number of organized hate groups more than doubled between 1940 and 1946. In his latest book, The Secret War Against Hate: American Resistance to Antisemitism and White Supremacy, Ross tells the story of the or
How to be grateful to someone – even when you don’t want to (opens the original)
Read excerpt
There are few greater feelings than the sense of heartfelt gratitude to another human being who has done you a solid. Sincere thanks and reciprocation are part of the glue that binds us in human relationships. But sometimes you’re just not feeling it. You know that you have benefited from what someone has done for you, but you don’t really feel grateful to them for doing it. Most teenagers go through this period with their parents. Maybe you take your partner or colleague for granted. For me, 14
