Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically in one place only. This makes them particularly resistant. Researchers conducted a theoretical study that explains the mechanism underlying this phenomenon, which was experimentally observed in epithelial cell cultures.
Scientists are investigating a biodegradable nanomedicine that can selectively destroy ovarian cancer cells left behind after surgery. These findings are a step forward in the development of targeted therapies for hard-to-treat cancers.
Scientists have developed a new hybrid, solar-energy system that harnesses the full spectrum of the sun's radiation by pairing a photovoltaic cell with polymer films. The films convert the light that goes unused by the solar cell into heat and then converts the heat into electricity.
Scientists have developed a new paper device that analyzes DNA and could rapidly and inexpensively assess disparate conditions including hepatitis B and male infertility, which together affect millions of people around the world.
Researchers are developing technology to make pacemakers battery-free. The advancement is based upon a piezoelectric system that converts vibrational energy - created inside the chest by each heartbeat - into electricity to power the pacemaker.
