How to find marker genes in cell clusters
A new method facilitates identification of cell-type specific genes in single-cell data.
Differentiation of rickets and classic metaphyseal lesions on radiographs
Rickets and classic metaphyseal lesions (CMLs) exhibit distinct radiographic signs, and radiologists can reliably differentiate these two entities.
Gecko feet are coated in an ultra-thin layer of lipids that help them stay sticky
Researchers view, for the first time, the protein and lipid molecules on the surface of the microscopic structures that give geckos their grip. The new images, created using a synchrotron microscope (powered by a particle accelerator), open the way to …
New imaging technique allows researchers to see gene expression in brains of live mice in real time
Scientists have developed a new technique for imaging mRNA molecules in the brains of living mice. The research reveals new insights into how memories are formed and stored in the brain and could allow scientists to learn more about diseases such as Al…
Shapeshifting microrobots can brush and floss teeth
A robotic microswarm may one day automate the routine of rinsing, brushing, and flossing teeth. A multidisciplinary team developed the technology, which employs a magnetic field to direct the iron oxide nanoparticle-based microrobots into antimicrobial…
Researchers expand understanding of vortex spread in superfluids
Researchers have created a model that describes the spread and speed of tornado-like vortex tubes in superfluids. This work expands on a previous study that reported experimental results obtained in superfluid helium-4 within a narrow temperature range.
What is a pond? Study provides first data-driven definition
Nearly everyone can identify a pond, but what, exactly, distinguishes it from a lake or a wetland? A new study offers the first data-driven, functional definition of a pond and evidence of ponds’ distinct ecological function, which could have broad imp…
New research challenges long-held beliefs about limb regeneration
Researchers are challenging a centuries-old beliefs about how mammals might regenerate damaged parts of the body. In humans, the natural ability to regenerate is limited to tissues like the epidermis, the outermost layer of skin, and some organs, such …
Inhalable COVID-19 vaccine shows promise in rodent model
Researchers have created an inhalable COVID-19 vaccine that is shelf stable at room temperature for up to three months, targets the lungs specifically and effectively, and allows for self-administration via an inhaler.
