Rensselaer Polytechnic Institute researchers have developed a method to grow carbon nanotubes up, out, and in all three dimensions, providing unprecedented control over their growth. This breakthrough could lead to the creation of Lilliputian devices and complex networks comprised of molecular units.
Researchers found no statistical difference between sulindac and placebo groups in preventing polyp development or colon cancer, contradicting previous evidence. Sulindac may be ineffective at preventing polyps in newly diagnosed FAP patients, suggesting a need for alternative treatments.
Scientists have discovered a rare fossil of a brittle star with preserved fleshy tube feet, providing evidence of an ecological shift through time. The findings challenge traditional understanding of soft tissue preservation and offer new insights into the evolutionary history of starfishes.
A new low-voltage microelectromechanical systems (MEMS) switch has been developed for integration with existing technologies in high-speed electronics. The switch boasts a tiny metal pad that can move up or down in under 25 microseconds, providing a very low insertion loss of less than 0.1 dB.
A new study by Scripps scientists reveals that intermediate-sized predators can have significant impacts on ecosystems, contrary to previous conclusions. The research highlights the importance of considering all species, not just larger ones, for maintaining ecosystem stability and biodiversity.
A new framework for predicting underground rock geometry has been developed, enabling coal and gas companies to better understand their drilling operations. The research uses electric logs from wells and field work to interpret the types of sandstone bodies present, which are critical for finding deposits.
The NCCN has released new guidelines to address cancer-related fatigue and treatment-related anemia in cancer patients. The guidelines provide a framework for clinicians to assess and treat these conditions, with a focus on symptom management and improving patient outcomes.
A study of 93 patients hospitalised due to acetaminophen overdose found that those who accidentally overdosed fared less well, despite lower drug levels. Delayed treatment and alcohol consumption exacerbated liver damage and death risk.
Researchers studied sandstone formation in Pennsylvanian time period to understand climate, environment, and grain influences on diagenesis. They found quartz cement played a significant role in storing silica-rich fluids, potentially leading to discoveries of oil, gas, or water.
A University of Toronto geochemist has found evidence of abiogenic gases in underground mines, matching hydrocarbons formed from non-life-based reactions. The discovery raises the possibility that life on Earth could be sustained by these gases, challenging previous assumptions about the origins of complex life.
A new study suggests that taking supplements of both vitamins C and E can significantly reduce coronary arteriosclerosis in heart transplant patients. After one year, the group receiving antioxidants showed little to no thickening and narrowing of their coronary arteries, while those receiving a placebo experienced significant changes.
Researchers found that when treatment outcomes were impaired quality of life, such as severe functional or cognitive impairment, a significant number of patients (74.4% and 88.8%) lost their willingness to receive treatment. In contrast, the impact on preferences was more nuanced with mortality, where only when the likelihood increased...
