Peppercorn-sized clumps of human brain cells grown in a lab for a record seven years aged similarly to those inside our heads, suggesting they "recorded the passage of time," scientists said Wednesday.
The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, ...
A new genetic screening method allows researchers to efficiently modulate individual genes across entire tissues and provides new insights into human development. The research, published in eLife, is described as a landmark ...
An international team, including the University of Tokyo, has created a sensor inspired by the lateral line in fish—their "sixth sense" organ—which measures the pulse of lab-grown 3D heart tissue (cardiac organoids). The ...
Human embryo models can help researchers study early human development and infertility without relying solely on human embryos. As the technology advances, these models are becoming more complex and can be maintained in culture ...
Korea Research Institute of Standards and Science has developed a toxicity assessment system that automatically measures and analyzes the heart rate of Daphnia magna. Capable of processing heart rate data from approximately ...
Researchers at The Hong Kong University of Science and Technology (HKUST) have uncovered how mutations in a specific gene can trigger a rare respiratory disease, shedding light on the critical role played by cellular structures ...
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: ...
Until now, studying the genetic processes in cells required destroying them—making it impossible to observe these processes over extended periods of time. A team from the Technical University of Munich (TUM) and Helmholtz ...
Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the slide, the image blurs, and you have to stop and carefully turn a knob to bring everything back into ...
