Scientists have shown that the ability of tissues to orient their growth in response to externally applied forces is a simple consequence of the mechanics of cellularised materials and the ability of individual cells to divide along their long axis.
Biological and medical scientists have been using flow cytometry to count cancer cells for the past 40 years. But the large instruments are expensive and can only be operated by trained personnel. By contrast the PoCyton cytometer is cheap to produce, no bigger than a shoebox, and automated.
Scientists have created an enzyme that could potentially solve this problem. The enzyme works by snipping off the sugars, also known as antigens, found in Type A and Type B blood, making it more like Type O. Type O blood is known as the universal donor and can be given to patients of all blood types.
