Multicellular life depends on remarkable acts of cooperation. Every cell in the human body must sense what is happening around it, interpret signals from its neighbors and respond in ways that support the larger tissue. These ...
Heat waves are arriving sooner and becoming hotter, with the United Kingdom recording May 25 as its hottest day in May since tracking began more than a century ago, only for the record to be broken again the next day. While ...
For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.
How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells still perform a version of that feat every time an embryo begins to take shape?
Cells are typically studied outside the body under controlled laboratory conditions. However, conventional flat cell culture methods do not fully reproduce the complex three-dimensional environments that cells experience ...
Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once ...
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the proportions of different ...
What are the first steps that chart the path for a cell to become a blood cell, neuron cell, or pigment cell? Scientists have developed increasingly powerful tools to track those changes, but one challenge has persisted: ...
Dr. Ainara Ballesteros is a Juan de la Cierva postdoctoral researcher at the Institute of Environment and Marine Science Research at the Catholic University of Valencia, where she leads a research group focused on jellyfish ...
The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined which cells will give rise to which tissues—controlled by epigenetic marks such as DNA methylation. ...
