Gene therapy technique thwarts cancer by cutting off tumor blood supply

University of Florida researchers have come up with a new gene therapy method to disrupt cancer growth by using a synthetic protein to induce blood clotting that cuts off a tumor's blood and nutrient supply.

What really prompts the dog's 'guilty look'

Amsterdam, 11 June 2009 - What dog owner has not come home to a broken vase or other valuable items and a guilty-looking dog slouching around the house?

Zero tolerance alcohol policy good choice for parents

Restaurants in Germany legally sell alcohol to teenagers after their sixteenth birthdays and French children drink wine with dinner at an early age, but U.S.

Fatal brain disease at work well before symptoms appear

GAINESVILLE, Fla. -- University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others -- a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

Fossil teeth of browsing horse found in Panama Canal earthworks

Rushing to salvage fossils from the Panama Canal earthworks, Aldo Rincon, paleontology intern at the Smithsonian Tropical Research Institute, unearthed a set of fossil teeth. Bruce J.

New, light-driven nanomotor is simpler, more promising, scientists say

GAINESVILLE, Fla. -- Sunflowers track the sun as it moves from east to west. But people usually have to convert sunlight into electricity or heat to put its power to use.

Now, a team of University of Florida chemists is the latest to report a new mechanism to transform light straight into motion -- albeit at a very, very, very tiny scale.

Scientists identify gene for deadly inherited lung disease

HOUSTON (June 4, 2009) -- A rare, deadly developmental disorder of the lungs called alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) that usually kills the infants born with it within the first month of life results from deletions or mutations in the FOXF1 transcription factor gene, said a consortium of researchers led by Baylor College of Medicine (

Soap-sniffing technology encourages hand washing to reduce hospital-acquired infections, save money

Call it a Breathalyzer for the hands.

Using sensors capable of detecting drugs in breath, new technology developed at University of Florida monitors health-care workers' hand hygiene by detecting sanitizer or soap fumes given off from their hands.

UF study finds ancient mammals shifted diets as climate changed

GAINESVILLE, Fla. --- A new University of Florida study shows mammals change their dietary niches based on climate-driven environmental changes, contradicting a common assumption that species maintain their niches despite global warming.

Scientists use high-energy particles from space to probe thunderstorms

MELBOURNE, FLA.?Florida Institute of Technology researchers are trying to solve one of the great mysteries in nature: how thunderstorms make lightning. Because, in principle, lightning is a big spark it should behave like other sparks?like the ones created when we touch a door knob on a dry day.

UF makes gene therapy advance in severe genetic disorder

GAINESVILLE ? A dog born with a deadly disease that prevents the body from using stored sugar has survived 20 months and is still healthy after receiving gene therapy at the University of Florida ? putting scientists a step closer to finding a cure for the disorder in children.

Research suggests new cellular targets for HIV drug development

GAINESVILLE, Fla. ? Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.

Biologists: Greening Arctic not likely to offset permafrost carbon release

GAINESVILLE, Fla. --- As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere.

At the same time, plants will proliferate, nurtured by balmier temperatures, more nutrients from decomposing soil and the increasing abundance of the greenhouse gas they depend on for growth.

Nervous system may be culprit in deadly muscle disease

GAINESVILLE, Fla. ? Brain may win out over brawn as the primary cause of breathing problems in children with a severe form of muscular dystrophy known as Pompe disease.

'Biodiversity beyond the habitat's borders'

Recently, images of melting sea ice and shrinking rainforests have highlighted the world's biodiversity crisis and made us aware of the need to find a balance between preserving natural ecosystems while still having enough land for human use.
