• Study: Advantages of single-sex schooling a myth Sept. 22, 2011 As Madison deals with a proposal to establish a single-sex charter school, a University of Wisconsin–Madison professor of psychology is one author of an article that calls the scientific case for single-sex schools "pseudoscience."
• UW–Madison botanist plucks new flower from Isle Royale Sept. 22, 2011 One of the world's newest sunflower species, discovered by a University of Wisconsin-Madison botanist, has carved out a very small but safe niche on an island in Lake Superior.
• Wisconsin engineer, entrepreneur move ‘green’ diesel engine closer to market Sept. 19, 2011 A University of Wisconsin-Madison engineer is collaborating with a Wisconsin entrepreneur to produce a diesel engine that could be a quieter, more efficient power source for a variety of household and industrial applications, including lawn equipment and electric generators.
• Mouse genome sequences reveal variability, complex evolutionary history Sept. 15, 2011 The genome of even a single organism is packed with information. A new paper, building on recent advances in sequencing capability, now reports the complete genomes of 17 different strains of mice, creating an unparalleled genetic resource that will aid studies ranging from human disease to evolution.
• Interim chancellor’s memo to lawmakers regarding proposed fetal tissue ban Sept. 14, 2011 Here is the text of a memo sent by UW–Madison Interim Chancellor David Ward to all members of the state Legislature regarding a bill that would ban the acquisition and use of fetal tissue in scientific research.
• Study reveals critical similarity between two types of do-it-all stem cells Sept. 11, 2011 Ever since human induced pluripotent stem cells were first derived in 2007, scientists have wondered whether they were functionally equivalent to embryonic stem cells, which are sourced in early stage embryos.
• In cell culture, like real estate, the neighborhood matters Aug. 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.
• Organic Field Day set Aug. 30 Aug. 22, 2011 University of Wisconsin-Madison researchers will host an Organic Field Day on Tuesday, August 30 from 1–3:30p.m. at the UW Arlington Agricultural Research Station.
• New neutrino detection experiment in China up and running Aug. 15, 2011 Deep under a hillside near Hong Kong, a pair of new antineutrino detectors are warming up for some serious physics.
• Is hunting wolves key to their conservation? Aug. 5, 2011 Hunters have been credited with being strong conservation advocates for numerous game species in multiple countries. Would initiating a wolf hunt invoke the same advocacy for the carnivores?
• Digitization project promises lichens and mosses at our fingertips Aug. 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.
• Award allows UW biochemist to investigate mitochondria mystery Aug. 1, 2011 Every student of basic biology learns that mitochondria are the powerhouses of the cell - little factories turning oxygen and food into energy.
• UW study finds that larger dairy farms tend to have better milk quality Aug. 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.
• Sea level rise less from Greenland, more from Antarctica, than expected during last interglacial July 28, 2011 During the last prolonged warm spell on Earth, the oceans were at least four meters - and possibly as much as 6.5 meters, or about 20 feet - higher than they are now.
