University of Wisconsin-Milwaukee (UWM) have identified an inexpensive nanorod catalyst with efficiencies rivalling that of platinum. Composed of nitrogen-enriched iron-carbon nanorods, the new catalyst holds the promise of cheaper, more efficient microbial fuel cells (MFCs) that generate their own hydrogen from waste water Read More
Storing solar energy for the periods of time when the sun isn’t shining is key to improving solar technology. The energy produced can be stored in batteries or used to produce fuel that can act as storage. Solar fuel processes are generally modeled on photosynthesis, the natural process whereby plants convert sunlight into chemical energy in the form of biomass and release oxygen into the atmosphere. Current options are expensive, but a group or researchers from the University of Wisconsin-Madison claim they have found a faster, cheaper method to find electrocatalysts that improve the water oxidation process in the search for solar energy storage.

Scientists – and dogs – have known for some time that our breath can reveal much more about us than our estimated blood alcohol content. Researchers at the University of Wisconsin-Madison believe that “breathalyzer”-like technology they currently have under development could be used to diagnose a wide range of diseases, such as diabetes, cancer and infections. Such technology, which relies on the fact that many diseases alter the body’s metabolism in distinctive ways, would provide a non-invasive method of detecting disease even before typical symptoms appear.

One of the biggest hurdles facing the developers of biological implants is coming up with a power source to keep the implanted devices ticking. We've seen various technologies that could be used instead of traditional batteries (which require the patient to go under the knife so they can be replaced) such as wireless transmission of power from outside the body, biological fuel cells that generate electricity from a person's blood sugar, and piezoelectric devices that generate electricity from body movements or the beating of the heart. Now researchers have developed a device that could be used to generate electricity from a patient's breathing. Read More
Although you may not be using a Get Smart-style shoe phone anytime soon, it is possible that your mobile phone may end up receiving its power from your shoes. University of Wisconsin-Madison engineering researchers Tom Krupenkin and J. Ashley Taylor have developed an in-shoe system that harvests the energy generated by walking. Currently, this energy is lost as heat. With their technology, however, they claim that up to 20 watts of electricity could be generated, and stored in an incorporated rechargeable battery. Read More
After five years of construction, an international team has put the finishing touches on the University of Wisconsin’s IceCube Neutrino Observatory. Located in Antarctica, the observatory is looking specifically for high-energy neutrinos, which are created in violent cosmic events such as super novae and gamma ray bursts. As neutrinos collide with water molecules in the pitch black, ultra-clear ice, a blue flash of light results, which is detected by the sensors. Ever since neutrinos were discovered in 1956, scientists have hoped to decipher the information these astronomical messengers carry about distant cosmic events and the completion of the observatory marks an important step towards tracing their origins.

After two decades of planning, the world’s first kilometer-scale neutrino observatory should finally be completed by this December. Named IceCube, it will consist of an array of 5,160 optical sensors embedded within one cubic kilometer of the Antarctic ice shelf – to put the accomplishment in perspective, one of the next-largest such observatories is just 40 cubic meters in size. Its main purpose will be to try to establish, once and for all, the source of cosmic rays. Read More
If you're looking for an easy way to make your contribution to saving the planet, then it could be as simple as switching your font to 'Century Gothic'. University of Wisconsin - Green Bay (UWGB) has rolled out the change this semester, saying it uses 30% less ink than its default font Arial when printed. Read More
We recently looked at a breakthrough in using sunlight to create hydrogen but now scientists have found a way to use ambient noise to turn water into usable hydrogen fuel. The process harvests small amounts of otherwise-wasted energy such as noise or stray vibrations from the environment to break the chemical bonds in water and produce oxygen and hydrogen gas.

Remarkable new imaging technology developed by researchers at the University of Wisconsin can not only capture the heart in 3D showing blood flow, direction, and velocity, but can also show them relating to a fourth dimension - time. The procedure is fast, and requires no invasive procedures, no contrast agent or general anesthesia and could have significant consequences for patients at risk of cardiac problems. Read More
