Cells, they're all different. Even two similar-looking cells that are supposed to work together in the same tissue might express completely different traits, and make different proteins. So how do you make left and right of it all?

In a scientific first, researchers have discovered a bizarre inter-species relationship in which salamanders and algae cosy up together to share cells. Scientists aren't entirely sure why these two very different organisms have adopted such an intimate arrangement, but the discovery could represent a completely new form of symbiotic relationship.
Using skin cells extracted from mice, researchers in Japan have produced fully functional egg cells that were used to produce healthy mouse pups. Should the method work in humans, it could introduce powerful new ways of treating infertility -- and even allow same-sex couples to produce biological offspring.
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.
Scientists say that a groundbreaking fertility treatment to correct potentially harmful genetic mutations has the potential to backfire, recreating the exact mutation the intervention was meant to fix. It's a problem that could put an immediate halt to the pending practice -- but a work-around may be possible.
Scientists have sustained human embryos in a petri dish for 13 days, shattering the previous record of nine days. The breakthrough will allow researchers to study early foetal development in unprecedented detail, and brings us one step closer to viable "artificial wombs". But it's adding fuel to an already heated ethical debate.
