This microscope photo provided by the Mayo Clinic in August 2022 shows senescent myoblast cells. Senescent cells resist apoptosis, or programmed cell death, and characteristically get big and flat, with enlarged nuclei. They release a blend of molecules, some of which can trigger inflammation and harm other cells — and paradoxically also stimulate the growth of malignant cells and fuel cancer, says Mayo Clinic researcher Nathan LeBrasseur.

This microscope image provided by researchers Gianluca Amadei and Charlotte Handford in August 2022 shows a synthetic mouse embryo with colors added to show brain and heart formation. According to a study published in the journal Nature on Thursday, Aug. 25, scientists have created “synthetic” mouse embryos from stem cells without a dad's sperm or a mom's egg or womb.

Scientists have created “synthetic” mouse embryos from stem cells without a dad's sperm or a mom's egg or womb.

The lab-created embryos mirror a natural mouse embryo up to 8 ½ days after fertilization, containing the same structures, including one like a beating heart.
