Wounds may trigger 'aged' cells within hours, reshaping how senescence starts
Wounds may trigger 'aged' cells within hours, reshaping how senescence starts Sadie Harley Scientific Editor Robert Egan Associate Editor What if a process we associate with aging actually helps the body heal? A study led by Mikolaj Ogrodnik, LBI Trauma, published in Nature Cell Biology, shows that cells enter a state of senescence within minutes to hours after an injury—and that this rapid response not only plays a key role in wound healing, but also changes the paradigm of how slowly...
Embryonic tissues can behave like fluids or solids to reshape cell fate signals
Embryonic tissues can behave like fluids or solids to reshape cell fate signals Sadie Harley Scientific Editor Robert Egan Associate Editor Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize themselves following incredibly precise patterns, while remaining flexible and robust. Scientists are increasingly probing the role the physical properties of embryonic tissues—such as rigidity or stiffness—play in this process.
‘Virtual cells’ aim to turn raw data into predictive models of biology
Nature, Published online: 02 June 2026; doi:10.1038/d41586-026-01731-1Simulations of biological systems could transform biomedical research, but researchers are still learning how to reproduce life’s complexity without drowning in data.
A new origin story for multicellular life points to physics, not genes alone
A new origin story for multicellular life points to physics, not genes alone Sadie Harley Scientific Editor Robert Egan Associate Editor 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? In a new Perspective paper appearing in the journal Nature Biotechnology, Bren Professor of Biology and Biological Engineering Magdalena Zernicka-Goetz...
Scientists unveil ten-year roadmap for building synthetic cells
Scientists from six Asian countries have launched an ambitious 10-year effort to build synthetic cells from non-living molecules, marking the region's first coordinated push to create an artificial single-celled biological system. The roadmap, published on May 26 in Nature Biotechnology and led by the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, was developed through the SynCell Asia Initiative, which comprises more than 100 scientists from China, Japan,...
Chinese scientists leave posts after whistle-blower raises alarm over their research
Chinese scientists leave posts after whistle-blower raises alarm over their research The trio faced heightened scrutiny after a former doctoral student and blogger known as Student Geng raised questions about their work Nankai University in Tianjin announced on Saturday that Chen Quan had been removed as dean of its College of Life Sciences. The university said that Chen, as a corresponding author, failed to properly oversee the quality and authenticity of experimental data in a paper...
Elasto-Osmotic Phase Separation in Confluent Cellular Tissues
Biomolecular condensates that form via liquid-liquid phase separation (LLPS) of, most prominently, intrinsically disordered proteins (IDPs) are ubiquitous in eukaryotic cells and responsible for regulating a plethora of biological functions. Amongst these, they contribute to regulating cell motility, either individually within an extracellular matrix or collectively within confluent epithelial tissue. In this computational study we focus on the latter with the aim of investigating whether...
SIRT7 regulates dosage compensation and safeguards the female X chromosome
Abstract Sirtuins are deacetylases implicated in stress responses and longevity in mammals1,2. Although their differential impact on disease for the two sexes has been noted3,4,5,6,7, the underlying reasons are unclear. Here, using Sirt7 as a model in mice, we examine the mechanisms leading to sex differences and find that Sirt7−/− female mice have decreased fitness throughout their lifespan.
Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects
Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects Gaby Clark Scientific Editor Robert Egan Associate Editor Potent drugs like chemotherapy can be life-saving, but often with life-threatening side effects. Notably, they can be indiscriminate, killing both cancer cells and healthy cells in one swoop. Increasing a drug's on-target efficiency can reduce side effects and enable healthier outcomes for patients.
Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that form highly complex three-dimensional structures. Because of their size and shape, scientists believe such oligomeric MIAs may be able to interfere with specific protein–protein interactions inside cells—a biological target that conventional small-molecule drugs often...
