Researchers have developed a new model that accurately predicts Dungeness crab population fluctuations, combining internal and external factors. The study provides a rare instance where a modeled understanding agrees with field data, offering insights into the elusiveness of population predictability.
Scientists have identified a new factor regulating lymphatic vessel growth, which may lead to ways of repairing damaged vessels and better understanding of certain types of cancer. The discovery of VEGF-C could also improve healing after lymph node removal in breast cancer surgery or prevent tumors affecting the lymphatic system.
A recent NIH study suggests that a significant number of people, particularly those with a specific genetic variant, may require increased folate intake to compensate for their genetic deficiency. This finding has implications for the recommended daily allowance and may lead to reviews of dietary reference values.
University of Pennsylvania researchers discover three-dimensional atomic structure of vancomycin using X-ray diffraction analysis. The advance provides detailed knowledge about the vancomycin molecule to help design new antibiotics effective against vancomycin-resistant bacteria.
Researchers have identified a gene, CBFA1, essential for bone-forming cells to arise in the embryo. Disruption of this gene causes cleidocranial dysplasia, a developmental disorder that stunts bone growth.
A new hominid species, Homo antecessor, has been identified in Spanish fossils, dating back 800,000 years. The species' modern-looking mid-face and primitive cranium traits suggest a complex evolutionary history, potentially challenging current theories on human migration and settlement of Europe.
Researchers at Johns Hopkins Medicine have successfully delivered genes to nearly 100% of muscle cells in a rabbit heart using a disabled adenovirus as a carrier. This breakthrough could pave the way for gene therapy to treat various heart diseases, including congestive heart failure and familial hypertrophic cardiomyopathy.
Contrails can indeed influence regional climate due to their potential to increase cloud cover, which can disrupt the radiation balance and affect climate. The study suggests that contrails may be more significant than previously thought due to their ability to modify energy distribution and feed other cloud formation processes.
Researchers at the University of Chicago found a protein molecule that transmits genetic traits without DNA or RNA in yeast, forming long fibers like those seen in neurodegenerative diseases. This discovery sheds light on the mechanism behind these devastating brain disorders.
