Researchers from Tokyo Metropolitan University found that genes on newly formed neo-sex chromosomes in fruit flies tend to evolve sex-biased genes, which give sex-specific phenotypes. This strongly supports the hypothesis that sex chromosomes reduce sexual conflict by imparting beneficial traits to each sex.
Global regulatory bodies, particularly in low- and middle-income countries, need enhanced capacity to ensure timely and safe access to essential medical products. Experts suggest expanding regulatory pathways to prioritize public health by enabling faster reach of diagnostics, therapeutics, and vaccines.
A review article discusses optimization algorithms for computer-generated holography (CGH), improving hologram reconstructing accuracy. Non-convex optimization methods are applied to seek optimal solutions, addressing the ill-posed inverse problem in CGH.
