Rusty crayfish kept at bay in Wisconsin

By Brita Larson and By James Lanser | Oct. 1, 2013

Imagine an underwater army of crustaceous lumberjacks chopping down the kelp forests on the floor bed of lakes with their large pincers. This isn’t something out of a science-fiction movie. This is how the Rusty Crayfish, an invasive species from Ohio River Basin, essentially deforested Sparkling Lake in Vilas County, Wisconsin.

Plants eavesdrop as a means of defense

By Danielle Smith | Sep. 17, 2013

Imagine yourself in a situation in which you and everyone surrounding you are being attacked by an unknown predator. You hear signs of chaos all around you and your fight-or-flight instincts are gearing up to protect you from impending doom. You are just about to plan your miraculous escape when you notice your feet are stuck planted to the ground, and you are incapable of fleeing the scene. What would you do to protect yourself?

Childhood stresses may trigger the later onset of anxiety in girls

By Danielle Smith | Sep. 2, 2013

When exposed to high-stress situations, the normal physiological reaction is for the body to release a hormone called cortisol, which prepares people for a fight-or-flight response to the stressor. However, according to a study done at the University of Wisconsin-Madison in the laboratory of psychology professor Seth Pollak, this reaction does not occur in girls who experienced physical abuse in their developmental years.

Stem cell research shows promise of memory restoration

By Nia Sathiamoorthi | Jul. 9, 2013

You simply can’t remember where you put your keys. It’s fine, happens to everybody and you are just getting older. Good-humoredly, you even start calling yourself “absentminded.” Then, one day, you cannot remember your boss’s last name. You start forgetting the stores you’ve been to, where you went for vacation last year, or what your favorite meal is. You forget how to use the bathroom or when to eat, and the people you care about fade in and out of your memory.

Rust-less steel and nano-paint future of UW Engineering

By Ali Branscombe | Jun. 3, 2013

Most people on the University of Wisconsin-Madison campus walk past the old, three-story brick building along Lakeshore path without a second thought. On the outside, it looks like an abandoned warehouse used for storing lab equipment or boats from Lake Mendota in the winter. What is actually inside is more surprising: a nano-technology development lab that could change life as we know it.

Microbes May Set Squid's Internal Clock

By Nia Sathiamoorthi | Jun. 3, 2013

Growing up in an antibiotic age has predisposed many of us to think of all bacteria as harbingers of death and disease. We see them as things to be wiped, washed and scrubbed away. But for the past decade or so, the research, consistently proving the essentiality of microorganisms to human life, has us changing our tune. Because the truth is, we live in a bacterial world. Microorganisms in and on our body outnumber human cells 10 to one, and it can be argued we are more bacteria than we are human. And instead of threatening us, they keep us healthy by supporting basic physiological processes from digestion to defense.
