Saccharin could sweeten the deal for cancer-fighting drugs

By - March 23, 2015 1 Picture
Whether it be advice from a dentist or preparing their body for beach season, there's a host of reasons people might reach for an artificial sweetener rather than sugar – though its cancer-fighting properties are unlikely to be one of them. But new research shows that the common sugar substitute known as saccharin could hamper the growth of particular cancers, with scientists claiming it could form the basis for new kinds of drug treatments.

Converting human waste into rocket fuel

By - November 26, 2014 1 Picture
Flushing the human waste produced on space missions out an airlock isn't an option for astronauts. Currently its stored in containers before being loaded into cargo vehicles that burn up as they pass through Earth's atmosphere, but researchers at the University of Florida (UF) have found a better use for the material, by developing a process to turn it into rocket fuel.

Micro storm-studying vehicles designed to hitch rides with hurricanes

By - June 6, 2013 3 Pictures
When we think of aircraft that study hurricanes, most of us probably either picture powerful manned airplanes that fly straight through them, or perhaps unmanned drones that fly safely over them. The University of Florida’s Prof. Kamran Mohseni has something else in mind, however. He’s developing tiny unmanned aircraft – and submarines – that will be swept up with the hurricane, gathering data on the strength and path of the storm as they go. Read More

Doping leads to new efficiency record for graphene solar cells

By - May 25, 2012 1 Picture
Doping graphene with trifluoromethanesulfonyl-amide (TFSA) has enabled researchers at the University of Florida (UF) to set a new efficiency record for graphene solar cells. While the record-breaking efficiency of 8.6 percent is well short of the efficiencies seen in other types of solar cells, it is a big improvement over previous graphene solar cells that saw efficiencies ranging up to 2.9 percent. The development provides hope for cheaper, durable graphene solar cells in the future. Read More

Pill tells doctors when it's been swallowed

By - March 31, 2010 1 Picture
Patients forgetting, bungling or just plain refusing to take their medication is a big problem for health care professionals and patients alike. It can exacerbate medical problems, spurring hospitalizations or expensive medical procedures and undercut clinical trials of new drugs. In seeking a way to confirm that patients have taken their medication a team of researchers have added a tiny microchip and digestible antenna to a standard pill capsule that automatically alerts doctors when the pill has actually been ingested.

Spider-inspired water-repelling surface could lead to self-cleaning windows

By - February 25, 2010 1 Picture
In recent years the lotus leaf has been the go-to surface for scientists looking to develop high-tech water repelling surfaces. Now engineering researchers have created what they say is a “nearly perfect hydrophobic interface” by borrowing from another of nature’s wonders - spiders. By reproducing the shape and patterns of the minute hairs that grow on the bodies of spiders, the researchers have created what may be the most water-phobic surface yet... a development that could lead to everything from self-cleaning surfaces to faster boats.
