In cell culture, like real estate, the neighborhood matters

August 28, 2011

Ever since scientists first began growing human cells in lab dishes in 1952, they have focused on improving the chemical soup that feeds the cells and helps regulate their growth. But surfaces also matter, says Laura Kiessling, a professor of chemistry at the University of Wisconsin–Madison, who observes that living cells are normally in contact with each other and with a structure called the extracellular matrix, not just with the dissolved chemicals in their surroundings.

Digitization project promises lichens and mosses at our fingertips

August 2, 2011

Lichens and mosses are well-known barometers of the environment. But soon lichens and mosses could assume a new and much broader importance as harbingers of environmental change, thanks to an effort to digitize the lichen and moss collections of U.S. herbaria.

UW study finds that larger dairy farms tend to have better milk quality

August 1, 2011

Wisconsin's larger dairy operations tended to fare better than the state's small farms in a University of Wisconsin–Madison study of milk quality, although all of the state's farms - both large and small - produced milk that easily met federal food safety guidelines.
