Researchers from South Korea have engineered a strain of bacteria that infiltrates tumours and fools the body’s immune system into attacking cancer cells. In experiments, the modified bacteria worked to reduce cancer in mice, raising hope for human trials.
Using skin cells extracted from mice, researchers in Japan have produced fully functional egg cells that were used to produce healthy mouse pups. Should the method work in humans, it could introduce powerful new ways of treating infertility — and even allow same-sex couples to produce biological offspring.
Researchers from the University of Washington are the first to visualise the insidious way that the flu virus latches onto a cell and plows its way inside, causing an infection.
