T cells are white blood cells that are important for adaptive immunity. They have unique cell surface receptors that are generated by randomly assorting genes. These receptors allow T cells to ...

The standard specifies deterministic medium access control (MAC), based on dynamic time division multiple access (TDMA), as well as two physical ... and is capable of forming them into adaptive ...

Did you know that every single living thing is made up of teeny, tiny unit structures? You have more than 75 trillion of them in your body – they’re called cells and they are amazing! Today we are ...

Stem cells are specialized cells that have the potential to develop into not one but many different types of cell. They are unlike any other cell for three specific reasons: They are unspecialized, ...

Detailed maps that pinpoint the positions of cells in tumours and probe the tumours’ biology are offering insights into the development of several cancers — including in the breast ...

The protein factories of our cells are much more diverse than we thought they were. Scientists have now shown that cancer cells can use these so-called ribosomes to boost their invisibility cloak ...

What is sickle cell disease? Sickle cell disease (SCD) is an inherited blood disorder. That means it is passed down from a parent’s genes. It causes the body to make abnormal hemoglobin. Hemoglobin is ...

Along these lines, we propose a clustering-based heuristic scheduling scheme that maximizes the cell sum capacity, subject to a fixed number of reconfigurations within a TDMA frame. First, the best ...

CD4 T helper cells are a type of white blood cell called a lymphocyte that serves an important role in your immune system. These cells help defend the body against infection by directing other "killer ...
