(Phys.org)—Piece by piece, the circuit diagram for electron transport in the mitochondria has come closer to completion. Each new structure obtained for any of the five respiratory complexes further constrains the assembled ...
Re-routing anti-cancer drugs to the "power plants" that make energy to keep cells alive is a promising but long-neglected approach to preventing emergence of the drug-resistant forms of cancer—source of a serious medical ...

(Phys.org) —If you asked a biologist what any given cell is going to do next, they might ask you first to tell them its electrical potential, oxygenation, pH, osmolarity or glucose concentration. Depending on how finely-scaled ...
(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...
(PhysOrg.com) -- After taking a small dose of inorganic nitrate for three days, healthy people consume less oxygen while riding an exercise bike. A new study in the February issue of Cell Metabolism traces that improved performance ...
