The fluid that feeds tumor cells MIT biologists have found that the nutrient composition of the interstitial fluid that normally surrounds pancreatic tumors is different from that of the culture medium normally used to grow cancer cells.
New perspective on tumor genome evolution An interdisciplinary team of scientists at the Centre for Genomic Regulation in Barcelona, Spain, deepens understanding of tumor genome evolution and suggests negative selection acting on cancer-essential genes plays a more important role than previously anticipated.
Cancer: Tumor transition states Researchers at the Université libre de Bruxelles define for the first time the tumor transition states occurring during cancer progression and identify the tumor cell populations responsible for metastasis.

#556 The Power of Friendship It's 2020 and times are tough. Maybe some of us are learning about social distancing the hard way. Maybe we just are all a little anxious. No matter what, we could probably use a friend. But what is a friend, exactly? And why do we need them so much? This week host Bethany Brookshire speaks with Lydia Denworth, author of the new book "Friendship: The Evolution, Biology, and Extraordinary Power of Life's Fundamental Bond".
This episode is hosted by Bethany Brookshire, science writer from Science News.
Dispatch 1: Numbers In a recent Radiolab group huddle, with coronavirus unraveling around us, the team found themselves grappling with all the numbers connected to COVID-19. Our new found 6 foot bubbles of personal space. Three percent mortality rate (or 1, or 2, or 4). 7,000 cases (now, much much more). So in the wake of that meeting, we reflect on the onslaught of numbers - what they reveal, and what they hide.
