A study found that high-risk prostate cancer patients treated with seed implant therapy had poorer outcomes compared to radical prostectomy and external beam radiation. The researchers suggest that high-risk patients should discuss alternative treatment options with their physicians.
The Advanced Applied Technology Demonstration Facility has developed innovative technologies for hazardous waste cleanup, addressing difficult subsurface and ground water contamination problems. The partnership between government, industry, and academia has led to the creation of engineering design manuals and commercialization summaries.
Scientists have discovered archaea, an ancient branch of microbial life that can thrive in extreme environments like volcanic vents and acidic hot springs. These microorganisms produce enzymes that are stable under harsh conditions, offering potential benefits for environmental cleanup, pollution prevention, and energy production.
Astronomers Renyue Cen suggests that gamma-ray bursts might come from supernovae expelling material at high speeds, producing jets that travel at nearly the speed of light. This theory could explain why some pulsars are moving faster than ordinary stars and potentially pose a catastrophic threat to Earth.
The University of Delaware has received a $1.6 million HHMI grant to support interdisciplinary research projects, outreach efforts, faculty development, and new equipment for active learning methods. The grant aims to enhance undergraduate education in the biological sciences through problem-based learning.
Researchers have found an RNA molecule capable of making a nucleotide building block, providing strong evidence for the RNA world view. This discovery supports the theory that in early evolution, RNA molecules carried out functions now considered to be the domains of DNA and proteins.
Researchers have identified hyperforin as the primary active ingredient in St. John's Wort, leading to significant improvements in mood and cognitive function. Studies have shown that high concentrations of hyperforin produce greater brain wave activity and enhanced neurotransmitter release.
Scientists discover African Superswell is caused by hot mantle material rising from the core-mantle boundary, elevating southern Africa and driving tectonic plates. This phenomenon, known as dynamic topography, reveals a link between deep mantle dynamics and surface features.
A national survey of primary care doctors found that one in three doctors recommend herbal supplements for emotional balance and fatigue. The most commonly used herbs are St. John's Wort and ginkgo biloba, with 27% and 18% of doctors recommending them respectively.
A study of 206 patients with Alzheimer's disease found that those with the lowest genetic risk had fathers who were significantly older at birth. This suggests a possible link between paternal age and increased susceptibility to the disease, which could be influenced by environmental factors affecting the father's DNA.
