As one wise pundit recently observed, "everybody is a virologist now." For the many people whose interest in biology formerly began and ended with "the mitochondria is the powerhouse of the cell," a second axiom can now be ...
While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, Salk researchers have developed a new imaging method that lets them monitor a small ...

Humans have 46 chromosomes, and each one is capped at either end by repetitive sequences called telomeres. If you ask a biologist if humans have circular DNA, they are likely to say 'no.' That is because eukaryotic cell nuclei ...
If there's one fact that most people retain from elementary biology, it's that mitochondria are the powerhouses of the cell. As such, they break down molecules and manufacture new ones to generate the fuel necessary for life. ...

(Phys.org)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...
(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 ...
(Phys.org)—Many intuitions drawn from our machine world do not smoothly extended to the biological. Whereas the screws or other fasteners used in an automobile typically tend to loosen over time with use, the hardware found ...
