Researchers build anthrobots from human airway cells that self-assemble, move, self-heal, and reverse aging markers, offering insights into synthetic life systems. (Nanowerk Spotlight) What kinds of ...

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional objects inside living cells. Instead of sculpting tissue from the outside, they ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

During early development, tissues and organs begin to form through the shifting, splitting, and growing of many thousands of cells. A team of researchers headed by MIT engineers has now developed a ...

No modern laboratory is complete without at least one basic microscope, an essential tool for biologists in medical research. Transmitted light methods have largely been replaced by fluorescent ...
