There are massive telescopes that look far out into the cosmos, giant particle accelerators looking for ever tinier signals, gargantuan gravitational wave detectors that span kilometers of Earth—what about soil science? Where’s the big science project on deep soil? It’s coming soon. Staff Writer Erik Stokstad talks with host Sarah Crespi about plans for a new subsoil observatory to take us beyond topsoil. Wood is in some ways an ideal building material. You can grow it out of the ground. It’s not very heavy. It’s strong. But materials like metal and plastic have one up on wood in terms of flexibility. Plastic and metal can be melted and molded into complicated shapes. Could wood ever do this? Liangbing Hu, a professor in the department of materials science and engineering and director of the Center for Materials Innovation at the University of Maryland, College Park, talked with Sarah about making moldable wood in a new way. In a sponsored segment from Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for the Custom Publishing office, interviews Michael Brehm, associate professor at UMass Chan Medical School Diabetes Center of Excellence, about how he is using humanized mouse models to study ways to modulate the body’s immune system as a pathway to treating type 1 diabetes. This segment is sponsored by the Jackson Laboratory. This week’s episode was produced with help from Podigy.
