A new microscope developed at the Marine Biological Laboratory in Woods Hole, Massachusetts is allowing scientists track the position and orientation of individual molecules in living cells. It has the potential to reveal unknown aspects of molecular behaviour, including those that turn cells into agents of disease.

The Y chromosome, a chunk of genetic code that is unique to male animals, isn't just physically smaller than the X. It also contains far fewer genes. The X has more than 1000 genes, while the Y has fewer than 200 — and most of them don't even work. Why do men have this odd, stunted chromosome in their genomes?

If you've ever felt like your life's turned on its head, be thankful that you're not this little embryo — which turns itself inside out. This is the first footage ever captured of a living algal embryo turning itself inside out.

To get a super-detailed X-ray view inside a cell — right down to the individual molecules — scientists dunk the cell they're looking at in preservative chemicals. That not only kills the cell, it changes its internal structure ever so slightly, meaning researchers aren't getting an exact look at the cell's natural state. Now, scientists at Germany's DESY Research Center have found a way around that, with a technique that's produced the world's first X-ray of an individual living cell.

Cells are three-dimensional so it makes sense to study them in a three-dimensional context, right? That's what researchers from the University of Twente in the Netherlands thought, which is why they made these little cages for studying live cells, instead of using a flat petri dish.
