It’s called organoid intelligence, or OI, and it uses actual human brain cells to make computing “more brain-like.” OI revolves around using organoids, or clusters of living tissue grown from stem cells that behave similarly to organs, as biological hardware that powers algorithmic systems. The hope—over at Johns Hopkins, at …

A team of biologists from the University of Surrey, the MRC Laboratory for Molecular Biology, Wake Forest University and the École Centrale de Lyon has discovered that red blood cells generate an electric field voltage that appears outside and not just within, meaning each cell acts as a tiny electrode. …

The two novel types of neuroglial cells — usually referred to simply as glial cells or glia — may play an important role in brain plasticity and repair, according to new research led by the University of Basel. A glial cell of new type (green), arising from adult stem cells …

A team of scientists from the United Kingdom and Spain has demonstrated that a technique called fluorescence lifetime imaging microscopy in conjunction with a fluorescent probe can identify four-stranded ‘quadruple helix’ DNA structures within nuclei of live cells. Fluorescence lifetime imaging microscopy map of nuclear DNA in live cells stained …

A gene called GATA6 (GATA binding protein 6) regulates aging of human mesenchymal stem/stromal cells (MSCs), according to new research from the University of Wisconsin-Madison. When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response; by transcription factor-based cellular reprogramming, …

A researcher at the University of North Carolina School of Medicine has generated scanning electron microscopy images showing startlingly high SARS-CoV-2 viral loads on human bronchial epithelial cells. This SEM image shows SARS-CoV-2 virions (red) produced by human airway epithelia. Image credit: Camille Ehre, doi: 10.1056/NEJMicm2023328. Dr. Camille Ehre from …

Scientists have discovered a new population of taste cells that can detect multiple types of stimuli, including chemicals from different taste qualities. Most taste cells selectively respond to a specific stimulus type while broadly responsive cells respond to multiple taste qualities. Image credit: Jhanna Flora / Kathryn Medler. Taste buds …

Bearing Human Skin from Pluripotent Stem Cells A team of researchers from several U.S. institutions has created an organoid culture system that generates complex skin from human pluripotent stem cells.

A team of researchers at Northwestern University has discovered a type of retinal ganglion cell that may cause myopia when it dysfunctions. The study is published in the journal Current Biology. This image shows an ON Delayed retinal ganglion cell. Image credit: Adam Mani Gregory W. Schwartz, Northwestern University. This …

A process using human stem cells can generate heart cells belonging to the external layer, the epicardium, according to an international team of scientists from the Pennsylvania State University, the University of Wisconsin, Madison, Leiden University Medical Center in the Netherlands and AstraZeneca in Sweden. A model highlighting the specification …
