In a new study led by University of Maryland researchers, scientists discovered a gene that prevents blood flow to blind cavefish eyes during development. It is the same gene responsible for homocystinuria in humans.
Some people look at an equation and see a bunch of numbers and symbols; others see beauty. Thanks to a new tool created at Carnegie Mellon University, anyone can now translate the abstractions of mathematics into beautiful and instructive illustrations. The tool enables users to create diagrams simply by typing an ordinary mathematical expression and letting the software do the drawing.
Honeybees that specialise in grooming their nestmates (allogroomers) to ward off pests play a central role in the colony, finds a new UCL and University of Florence study published in Scientific Reports.
Unexpected results bring into question which decision-making strategies should be considered as optimal.
Neutrophils are critical immune cells for antimicrobial defense, but they can exacerbate a number of diseases, perhaps including COVID-19. The traditional approaches to study neutrophils in animal models are limited in specificity and effectiveness. EPFL scientists have now identified the problem and have developed a new, optimized model for studying the role of neutrophils in the context of disease.
Researchers from the RIKEN Center for Advanced Photonics and collaborators have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing the cells.
Commonly, each somatic cell in an organism holds the same amount of DNA. However, researchers have, for the first time, shed light on a process, which leads to tissue-specific differing DNA content in plants. With an unusually high efficiency rate of 100%, this programmed chromosome elimination mechanism could become a valuable genetic tool for plant breeding or medical applications.
Extracellular vesicles (EVs) play a role in the pathogenesis of malaria vivax, according to a study led by researchers from the Barcelona Institute for Global Health (ISGlobal) and the Germans Trias i Pujol Health Science Research Institute (IGTP). The findings, published in Nature Communications, indicate that EVs from P. vivax patients communicate with spleen fibroblasts promoting the adhesion of parasite-infected red blood cells. These data provide important insights into the pathology of vivax malaria.
Middle-aged and older adults who identify as lesbian, gay, or bisexual have higher rates of using certain substances in the past year than those who identify as heterosexual, according to a new study led by researchers at NYU Grossman School of Medicine and the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU School of Global Public Health.
