Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and, to date, can be recharged more than 2000 times, showing how several of the problems holding back the development of these devices could be solved.
Scientists announced an important advance in the field of cancer imaging and phototherapy, using a single-agent system that may ultimately change the efficacy of cancer surgery and treatment around the world.
Researchers have successfully constructed a fluorescent biosensor for serum albumin by carefully connecting the two color variants of a green fluorescent protein to the antigen binding fragment of an antibody.
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.
