  • Lab vials from Kawaoka lab Compound found to safely counter deadly bird flu Dec. 28, 2009 The specter of a drug-resistant form of the deadly H5N1 avian influenza is a nightmare to keep public-health officials awake at night.
  • Queent ant Like humans, ants use bacteria to make their gardens grow Nov. 19, 2009 Leaf-cutter ants, which cultivate fungus for food, have many remarkable qualities.
  • Researchers Paul Lambert (left) and Sang-Hyuk Chung FDA-approved drugs eliminate, prevent cervical cancer in mice Nov. 9, 2009 Researchers at the University of Wisconsin-Madison School of Medicine and Public Health have eliminated cervical cancer in mice with two FDA-approved drugs currently used to treat breast cancer and osteoporosis.
  • Photo of mouse listening Now hear this: Mouse study sheds light on hearing loss in older adults Nov. 9, 2009 Becoming "hard of hearing" is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030.
  • AIDS virus image War of the viruses: Could ancient virus genes help fight modern AIDS? Oct. 20, 2009 Almost 30 years into the AIDS epidemic, scientists have yet to find an effective vaccine against HIV, the virus that destroys the immune system and causes AIDS. HIV is perhaps the most adaptive virus ever seen, not only evading the immune system, but also antiviral medicines.
  • High-speed genetic analysis looks deep inside primate immune system Oct. 11, 2009 Viruses such as HIV and influenza take safe harbor in cells, where they cannot be recognized directly by the immune system. The immune response relies on infected cells announcing the presence of the virus by studding their exterior with fragments of the virus lurking within.
  • Cottontop tamarind Monkeys get a groove on, but only to monkey music Sept. 1, 2009 Music is one of the surest ways to influence human emotions; most people unconsciously recognize and respond to music that is happy, sad, fearful or mellow. But psychologists who have tried to trace the evolutionary roots of these responses usually hit a dead end. Nonhuman primates scarcely respond to human music, and instead prefer silence.
  • White blood cells Scientists make multiple types of white blood cells directly from embryonic and adult stem cells Aug. 11, 2009 In an advance that could help transform embryonic stem cells into a multipurpose medical tool, scientists at the University of Wisconsin-Madison have transformed these versatile cells into progenitors of white blood cells and into six types of mature white blood and immune cells.
  • Photo of lake mixing research Will a well-mixed, warmer lake doom invasive fish? July 30, 2009 The rainbow smelt, an invasive fish that threatens native species such as walleye and perch, may soon be feeling the heat - literally.
  • Photo of an American Robin Do Chicago’s suburbs hold the key to understanding West Nile virus? July 22, 2009 For a group of UW-Madison epidemiologists, the Chicago suburbs near Oak Lawn are proving to be the perfect laboratory for prying loose the secrets of West Nile virus, a pathogen carried by mosquitoes and birds that infects and sickens thousands of people each summer.
  • Image of H1N1 virus Study suggests H1N1 virus more dangerous than suspected July 13, 2009 A new, highly detailed study of the H1N1 flu virus shows that the pathogen is more virulent than previously thought.
  • Photo of monkey Reduced diet thwarts aging, disease in monkeys July 9, 2009 The bottom-line message from a decades-long study of monkeys on a restricted diet is simple: Consuming fewer calories leads to a longer, healthier life.
  • A mouse Mouse study reveals genetic component of empathy Feb. 12, 2009 The ability to empathize with others is partially determined by genes, according to new research on mice from the University of Wisconsin-Madison and Oregon Health and Science University (OHSU).
  • After 30 years, tamarins ride off into retirement Jan. 28, 2009 At an institution like UW-Madison, good research programs ebb and flow, the vagaries of funding and the involvement of the people who drive them. But sometimes ramping down a program of research presents special problems that require extraordinary actions for closure. Such was the dilemma for Chuck Snowdon, a professor of psychology who for decades has studied the behavior of the cottontop tamarin, an endangered New World primate.
  • New study shows persistence of anxiety July 2, 2008 We all know people who are tense and nervous and can't relax. They may have been wired differently since childhood.
  • In young mice, gregariousness seems to reside in the genes April 4, 2007 In a groundbreaking study, researchers from the University of Wisconsin–Madison have found evidence that social interactions among young mice result from basic motivations to be with one another. What's more, the researchers say, the extent of a young mouse's gregariousness is influenced by its genetic background.
