(Phys.org)—Synthetic biology combines science and engineering in the pursuit of two general goals: to design and construct new biological parts, devices, and systems not found in nature; and redesign existing, natural biological ...
Cell particles move more quickly through a crowded cellular environment when the crowding molecules are non-uniformly distributed. New research also shows that particle transport in crowded cells can actually be faster than ...
