UF Study Shows Tundra Fires Could Accelerate Climate Warming

GAINESVILLE, Fla. — After a 10,000-year absence, wildfires have returned to the Arctic tundra, and a University of Florida study shows that their impact could extend far beyond the areas blackened by flames.

In a study published in the July 28 issue of the journal Nature, UF ecologist Michelle Mack and a team of scientists including fellow UF ecologist Ted Schuur quantified the amount of soil-bound carbon released into the atmosphere in the 2007 Anaktuvuk River fire, which covered more than 400 square miles on the North Slope of Alaska’s Brooks Range. The 2.1 million metric tons of carbon released in the fire — roughly twice the amount of greenhouse gases put out by the city of Miami in a year — is significant enough to suggest that Arctic fires could impact the global climate, said Mack, an associate professor of ecosystem ecology in UF’s department of biology.

‘Combining Therapies Appears Safe, May Benefit Patients with Advanced Liver Cancer’

GAINESVILLE, Fla. — Few treatments exist for patients with advanced primary liver cancer, but University of Florida researchers have found a new way to broaden the range of options and potentially improve health outcomes by combining two treatments.

In the first study of its kind, the researchers combined sorafenib, the only Food and Drug Administration-approved pill for treating advanced liver cancer, with another routinely used therapy known as transarterial chemoembolization, which works by cutting off the blood supply to tumors. No unexpected toxic effects were seen, and the combo appears to have the potential to improve survival for certain groups of patients. (more…)

UF: Florida Population Soars in Century’s First Decade, But Rate is Slowing

GAINESVILLE, Fla. — Florida was again one of the country’s leaders in population growth in the last decade, but the growth rates over the past few years have been among the lowest in the state’s history, according to a new study by the University of Florida.

Florida’s permanent resident population increased by more than 2.8 million between 2000 and 2010 — an increase of 17.6 percent to 18,801,310. That mark was the third-largest numeric increase and the eighth-largest percentage increase in the country. However, the growth rate lagged behind previous periods for the state, and projections are the growth rate will steadily decline through 2040. (more…)

UF Study Finds Cats No. 1 Predator to Urban Mockingbird Nests

GAINESVILLE, Fla. — A new University of Florida study shows cats are the dominant predator to mockingbird eggs and nestlings in urban areas, prompting conservationists to urge pet owners to keep felines indoors at night.

The findings challenge assumptions that urban areas are places of refuge for nesting mockingbirds, a species researchers say plays an important role in controlling insect pests and serving as environmental indicators for metropolitan areas. (more…)

UF Researchers Find Quiet Protein Speaks Loudly in Fight Against Cancer

GAINESVILLE, Fla. — When a movie character says, “It’s too quiet,” that’s usually a sign something bad may happen.

Now, University of Florida researchers have discovered that when variations of a certain protein in our cells are too quiet, it may add to the risk that someone will develop lung cancer. When scientists restored the protein to its normal, active self, its cancer-inhibiting properties reappeared. (more…)
