Wisconsin team grows retina cells from skin-derived stem cells
A team of scientists from the University of Wisconsin–Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells - suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.
A new ‘bent’ on fusion
Success in cellular fusion - as occurs at the moment of conception and when nerve cells exchange neurotransmitters - requires that a membrane be bent before the merging process can begin, University of Wisconsin–Madison researchers have shown.
New approach to wound healing may be easy on skin, but hard on bacteria
In a presentation today (Aug. 19) to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin–Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing.
Engineered protein-like molecule protects cells against HIV infection
With the help of the human immunodeficiency virus (HIV) and molecular engineering, researchers have designed synthetic protein-like mimics convincing enough to interrupt unwanted biological conversations between cells.
Future angst? Brain scans show uncertainty fuels anxiety
Anyone who has spent a sleepless night anguishing over a possible job loss has experienced the central finding of a new brain scan study: Uncertainty makes a bad event feel even worse.
Curiosities: How big is space?
Space is probably infinite, but we can see only the part that contains stars or galaxies whose light has been able to reach us, says…
Scientists make multiple types of white blood cells directly from embryonic and adult stem cells
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.
Curiosities: How long can bacteria live outside humans?
Bacteria have vastly different survival abilities, says Jeri Barak, an assistant professor of plant pathology at UW–Madison. Many species normally live in soil…
GLBRC receives $8 million in Recovery Act funding

Curiosities: How many galaxies have humans discovered?
“We don’t know,” says Ed Churchwell, professor of astronomy. “We know it’s a very large number.” It’s in the hundreds of billions, Churchwell…
Team discovers gene for age-related cataracts
Participants in the University of Wisconsin–Madison's long-running Beaver Dam Eye Study have contributed to the discovery of a gene involved in cataracts in both aging humans and in mice.
Will a well-mixed, warmer lake doom invasive fish?
The rainbow smelt, an invasive fish that threatens native species such as walleye and perch, may soon be feeling the heat - literally.
Curiosities: Does a dark-colored car heat up more in the sun than a light-colored car?
The external color does not significantly affect how much the inside of a car heats up in the sun, says Sanford Klein, director of…
Curiosities: Why do cats hate water?
Because we teach them to hate it. There are plenty of cats that love water, according to Sandi Sawchuk, a clinical instructor at the…
Curiosities: Why do onions make us cry when we cut them?
Chopping onions unleashes a “chemical defense that onion plants have to protect themselves against insects and microbes,” says UW–Madison horticulture professor Irwin Goldman. We’re…
