‘Pop-up’ electronic sensors could detect when individual heart cells misbehave

Posted: 23 Dec 2021 08:30 AM PST

UC San Diego engineers developed a powerful new tool that directly measures the movement and speed of electrical signals inside heart cells, using tiny 'pop-up' sensors that poke into cells without damaging them. It could be used to gain more detailed insights into heart disorders and diseases.

Microorganism sheds new light on cancer resistance

Scientists describe T. adhaerens' unusual behavior, including its capacity to repair its DNA even after significant radiation damage and to extrude injured cells, which later die. The findings advance scientific investigations of natural cancer-suppression mechanisms across life. Insights gleaned from these evolutionary adaptations may find their way into new and more effective therapies for this leading killer.
