Technically speaking, an engine is a device that converts some form of energy into mechanical energy. Taking that definition ...

Graham Johnson, a computational biologist and scientific illustrator at the Allen Institute for Cell Science, recalls fantasizing at a lunch table, more than 15 years ago, about a computer model of a ...

Scientists have developed functional eggs from ordinary human skin cells, a proof of concept that could open up new ways to ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

The word “niche” implies a specialized environment. But to Fiona Doetsch, the stem cell niche is anything but. For brain stem cells, “the whole organism is the niche,” Doetsch told the audience at the ...

The vertebral bones that form the spine are derived from a distinct type of stem cell that secretes a protein favoring tumor metastases, according to a study led by researchers at Weill Cornell ...

Medical researchers use knockout cells to study how genes function and how genes can be used for medical treatments. For example, a knockout cell line for liver cancer might turn off a gene linked ...

There are various techniques that detect CTCs on the basis of markers. But a larger set of CTCs may otherwise be missed due to variable or no expression of protein markers. For the analysis of these ...
