Researchers reconstructed the color pattern of Psittacosaurus, a well-preserved dinosaur species. The findings suggest that it likely lived in a forest environment with diffuse light, and its countershading camouflage was effective against predators.
Scientists in Japan have successfully demonstrated the transplantation of stem cell-derived retinal cells generated from immunologically matched donor animals without the need for harmful immunosuppressants. MHC-mismatched grafts produced tissue damage and signs of immune rejection, while matched grafts survived without immunosuppression.
Scientists have created a new strategy for crafting one-dimensional nanorods from a wide range of precursor materials, offering precise control over diameter, length, and surface properties. The produced structures have potential applications in electronics, energy conversion, drug delivery, and cancer treatment.
Researchers find that lifting the ivory ban will not address the issue of elephant poaching, as the demand for ivory is too great. They recommend managing demand effectively and promoting alternative sources of income for communities living with elephants.
A University of California, Davis, study published in PLOS Genetics has identified a genetic component contributing to mosquitoes' host choice between humans and animals. Researchers sequenced the genomes of mosquitoes fed on humans and cattle, finding a chromosomal rearrangement called the 3Ra inversion linked to cattle feeding.
Researchers at Massachusetts General Hospital have identified a promising new approach to treating acute myeloid leukemia by inhibiting the enzyme DHODH, which promotes blood cell differentiation. This inhibition prompts the differentiation of leukemic cells, reducing their number and ability to propagate cancer.
A new screening strategy could quickly identify drugs with antiviral potential by repurposing existing medications for other conditions. The research revealed 110 human genes that could serve as antiviral targets for specific existing drugs.
Researchers have identified a protein in mosquito saliva that binds to and inhibits the Dengue virus, reducing its transmission to human cells and mice. The study suggests that targeting this protein could provide a novel approach to preventing disease transmission.
A study published in PLOS Pathogens found that progesterone treatment reduces influenza infection severity by reducing inflammation and boosting lung cell production of amphiregulin. Progesterone also promotes faster recovery from the infection.
