Scientists have discovered a new type of cell in the liver that plays a critical role in repairing damage. These "leader cells" are responsible for dragging healthy tissue into wounds as they heal ...
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...
In the beginning, one cell becomes two, and two become four. Being fruitful, they multiply into a ball of many cells, a shimmering sphere of human potential. Scientists have long dreamed of ...
For example, the endothelial tissue that lines the human gastrointestinal tract consists of several cell types. Some of these cells absorb nutrients from the digestive contents, whereas others ...
New Tool Provides Researchers With Improved Understanding of Stem Cell Aging in the Brain Mar. 27, 2024 — Researchers can use the light naturally thrown off by biological specimens to better ...

According to the report, a former sheriff of Mississippi County, Missouri, used a service called Securus to surveil targets’ cell phones, including a judge and other police officers. Securus ...
May 29, 2024 — A new method of drug delivery using proline, an amino acid found in chicken feathers and skin tissue, could be used to limit the side effects of chemotherapy and repair important ...
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...
It feels like the Splinter Cell remake has been on its way for a decent few years now, which isn't helped by the fact it's been a while since we heard anything official about the game. From what ...
