Researchers at the Salk Institute have discovered a toggle switch for aging cells. By controlling the growth of telomeres, it may eventually be possible to coax healthy cells to keep dividing and generating even in old age.
Science, man. An international team of scientists have made a major breakthrough in synthetic biology. For the first time ever, they were able to insert a man-made, custom-built chromosome into brewer's yeast to not only create a life form but one that also passes down its man-made genes to its offspring. We're closer…
This is a stunning 3D map that shows how six feet of of DNA can be crammed inside a single chromosome — a space that's only a hundredth of a millimeter across. Not surprisingly, it looks like something that would go well with meatballs.
Remember back in high school biology class when you had to sketch the structure of a cell? Chromosomes were always fun because you know they'd be these smooth X's stuffed with DNA. Well, I hate to break it to you, but science doesn't actually work like that.
Health kicks might help you feel better about yourself, but new research suggests that they could actually be reversing ageing at the cellular level, too.
Normally, an extra pair of chromosomes would be considered dangerous. But what if we could design our own? According to biologists, we could create custom-built chromosomes to fix a variety of health problems, and even give us new abilities. Here’s how a 24th pair of chromosomes could change our biologies forever.
A handy explainer for the oft-cited (but rarely elucidated) factoid that every single person on Earth was once female — or, at a minimum, gender-neutral.
