Winston Churchill knew it. Ernest Hemingway knew it. Leonardo da Vinci knew it. Every trendy office from Silicon Valley to Scandinavia now knows it too: there is virtue in working standing up. And not merely standing. The trendiest offices of all have treadmill desks, which encourage people to walk while working. It sounds like a fad. But it does have a basis in science.
As someone with a standing desk at both home and the office, I too could not be a bigger believer.
But something titanic is indeed happening. The pink dots are stem cells, and the video shows the development of a liver bud, something which can go on to look and act like a liver. Takanori Takebe and Hideki Taniguchi of Yokohama City University, in Japan, who made the video, have created working human-liver tissue.
Researchers have long dreamed that stem cells might be used to repair or replace damaged tissue, an aspiration known as regenerative medicine. Embryonic stem cells, in particular, are “pluripotent”, meaning they are able to become any other type of cell. And it is now possible to induce pluripotency in cells that have not come from embryos, thus circumventing the ethical minefield previously associated with obtaining them.
I’m not going to pretend to fully comprehend the ramifications of this, but it sounds like massive news.
The New York Times came up with a very visual way to show just how much of a beating Rafael Nadal’s wounded knee takes in one of his matches. Good time for his first-round escape today at the French Open.
