Discovery of a type of immunity that protects koalas' DNA from viruses has importance for the survival of koalas and our fundamental understanding of evolution. A team of scientists are studying tissue samples from koalas to understand how a unique type of cell responds to retrovirus infections, which cause diseases such as chlamydia and cancer.
Read moreScientists have developed a new and more accurate method to identify the molecular signs of cancer likely to be presented to helper T cells, which stimulate and orchestrate the immune response to tumors and infectious agents.
Read moreWhen it comes to being willing to explore more efficient options to solving a problem, monkeys exhibit more cognitive flexibility than humans, according to a new study.
Read moreA psychologist is reporting that hope increases in therapy and is a trait that predicts resilience and recovery from anxiety disorders, an important mechanism for therapists to restore in patients to move them forward toward recovery.
Read moreWomen receive poorer heart attack treatment than men, even when rates of diagnosis are the same, according to new research.
Read moreSynthetic biologists design transcriptional circuits that allow single-cell microbes to form networks that spur collective action, even in large communities. The work could lead to engineered microbes that treat conditions in gut microbiomes or communicate with bioelectronics.
Read moreHydrogen-containing substances are important for many industries, but scientists have struggled to obtain detailed images to understand the element's behavior. Researchers now demonstrate the quantification of hydrogen for different states of water — i.e., liquid, frozen and supercooled — for applications to eco-friendly fuel cells.
Read moreA multi-institutional team has brought attention to genomic structural variation as a previously unappreciated mechanism involved in altering DNA methylation, a form of gene control, in human cancers.
Read moreResearcher have uncovered a new geophysical phenomenon where a hurricane or other strong storm can spark seismic events in the nearby ocean as strong as a 3.5 magnitude earthquake.
Read moreResearchers have produced crops in Mars and moon soil simulant developed by NASA. The research supports the idea that it would not only be possible to grow food on Mars and the moon to feed future settlers, but also to obtain viable seed from crops grown there.
