Researchers Randolph Blake and Sang-Hun Lee found that humans can group elements into objects based on subtle changes in timing. By analyzing the precise timing of motion in a dense array of pinwheels, viewers could distinguish synchronized groups from individual elements.
Regular churchgoers live longer than those who seldom or never attend worship services. They can look forward to about seven more years of life beyond age 20. The research also revealed that women and blacks can enjoy especially longer lives if they are religiously active.
Researchers at Thomas Jefferson University have found that radiation therapy helps patients with localized prostate cancer live longer. After examining the results of 1560 patients who received radiation therapy alone for prostate cancer, they discovered that those with high-risk disease benefited the most from higher doses of radiation.
University at Buffalo engineers develop virtual-factory software called UB VR-Fact! that allows companies to design and simulate large-scale plants virtually. The software uses mathematical algorithms and models to simulate factory layout, production, and identify potential bottlenecks.
A new study found that mild psychological stress can temporarily increase blood levels of homocysteine, a chemical associated with the development of heart disease. Researchers discovered that brief periods of stress resulted in a sharp rise in homocysteine levels in middle-aged women.
The study identifies a mechanism by which the immune system eliminates dysfunctional T cells, which can lead to autoimmune diseases and cancer. The research suggests that continuous contact with class I MHC proteins is essential for maintaining the balance between cell survival and death.
Researchers at Johns Hopkins University have made a groundbreaking discovery, capturing the first atomic-level resolution of a protein-RNA complex from the ribosome. The study reveals the intricate 3D structure of RNA and how it's held together by a protein lynchpin.
Researchers at University of North Carolina at Chapel Hill and Rockefeller University have discovered that mammalian chromosomes end in loops, also known as telomeres. This finding has significant implications for our understanding of cell aging and cancer, providing a new way to think about molecular mechanisms.
Researchers at the University of Pittsburgh Medical Center discovered that bone marrow-derived cells can differentiate into functional liver cells, potentially repairing or replacing damaged livers. This breakthrough challenges traditional scientific dogma and opens up new possibilities for treating liver diseases.
Researchers analyzed fossilized eggshell samples to determine the impact of human activity on Australian ecology. They found that environmental factors other than climate have significantly influenced the continent over the past 65,000 years.
Researchers at NICHD discovered a gene, Lhx5, that controls the development of the hippocampus, a brain structure critical for learning and memory. The gene's inactivation leads to a malformed brain structure, highlighting its importance in complex brain function.
A recent study found that Duke Forest plots experienced a 25% growth increase over two years under high carbon-dioxide conditions. This suggests that forests could serve as a significant carbon sink, potentially offsetting half of the world's expected carbon dioxide emissions from fossil fuel combustion.
Researchers at the University of California San Francisco have found a way for cells to move accurately, using a dual molecular docking maneuver. However, a pathogenic microbe like Listeria monocytogenes can mimic this system, hijacking the cell's motility protein and causing infection.
Jefferson researchers report progress in using a vaccinia-based vaccine to treat advanced melanoma, with two patients achieving complete remission. The vaccine works by boosting the immune system with granulocyte macrophage colony stimulating factor (GM-CSF), but more research is needed to enhance the treatment.
Researchers have created an artificial capsule, dubbed a polymersome, that imitates many qualities of natural cells. The capsules can be made to encapsulate payloads such as genes or pharmaceuticals and are biocompatible, evading detection by the human immune system.
The American Chemical Society's 32nd Middle Atlantic regional meeting will explore topics such as plastics, environmental protection and medicinal chemistry. More than 700 attendees are expected, with presentations covering the latest research findings.
