Researchers at the University of Florida successfully prevented high blood pressure and its damaging effects on the heart and kidneys in laboratory animals. The study used gene therapy to decrease the effectiveness of angiotensin II, a hormone that regulates blood pressure, and showed promising results.
Researchers have discovered reproductive and hormonal problems in alligators from Lake Okeechobee, similar to those found in the highly polluted Lake Apopka. The study suggests that environmental toxicants can affect thyroid function and growth in animals.
A University of Florida study found that women who exercised at home lost more weight and maintained their progress longer than those in a group exercise program. The home-based workout group averaged over 25 pounds of weight loss, compared to 15 pounds for the group exercisers.
Researchers at the University of Florida found that urban development in Florida is increasing the spread of Upper Respiratory Tract Disease among gopher tortoises. The disease destroys respiratory and olfactory senses, leading to malnutrition and starvation.
Harvard and UF researchers identified a component of the human immune system that appears to prevent type 1 diabetes in a group of people at high risk. The protein interleukin-4 (IL-4) is produced in large amounts in these individuals and may suppress the arm of the immune system involved in the destruction of insulin-producing cells.
Researchers are documenting the existence of seizure-alert dogs that claim to detect seizures before they strike, offering hope for people with epilepsy. The study aims to determine if these phenomena are real and reliable, and how dog trainers approach training such dogs.
Researchers found that estrogen replacement therapy accelerated wound healing in elderly postmenopausal women, outperforming those not on hormone therapy. The study suggests that hormone replacement therapy may benefit chronic wounds in older patients.
African tortoise ticks found on imported reptiles in Florida may carry heartwater, an exotic disease that kills livestock and wildlife. The US is considered a serious threat to the cattle, sheep, and goat industries, with no practical treatment for infected animals.
Research suggests that aging has a modest impact on sensory perception, particularly smell, taste, and touch. Most older adults can detect scents and flavors similar to those of younger individuals.
Researchers at University of Florida have developed a small, mobile land mine detector using X-ray probe technology that accurately identifies type and location. The device could be available to governments and humanitarian agencies within a year.
Researchers at the University of Florida have built a 300-foot experimental runway to study the effects of lightning strikes on existing runway lighting systems. The runway, equipped with various lighting systems, will be struck by lightning-induced electrical discharges from rockets launched into dark skies.
Researchers at UF found that organic waste can improve roadside soil, allowing grass to grow and stabilize roadways. The compost adds nutrients and holds water, making conditions favorable for grass growth.
Researchers studied 93 gay men with HIV who showed no symptoms when they entered the trial. Stress levels were found to be significantly associated with disease progression, with higher severe life stress increasing the odds nearly fourfold over two years.
A new study using electron spin resonance dating has pushed back the age of Homo erectus remains to 27,000 to 53,000 years old. This finding challenges the Multiregional theory and supports the Out of Africa model of modern human origins.
A University of Florida scientist has discovered that ancient oysters grew faster over time, revealing a key mechanism in the evolution of larger animal species. This finding challenges the long-held assumption that gradual growth drove evolutionary changes.
