Just 5 millimetres wide, the tiny Turritopsis dohrnii has discovered how to cheat death. More commonly known as the immortal jellyfish, it has been silently invading oceans all over the world with its ever-increasing population—due to the fact it can age backwards. The jellyfish’s reproduction cycle involves the meeting of free-floating sperm and eggs, which then settle on a hard surface and form a blob-like polyp, which slowly matures. Most mature jellyfish species die soon after reproducing, but the Turritopsis is able to transform from back into a polyp and restart life anew, inverting their ‘umbrella’ and absorbing their tentacles. This can only be done in an emergency such as starvation, physical damage, or temperature or salinity change, but the cycle can be repeated indefinitely, rendering the Turritopsis immortal. Remarkably, their cells are completely transformed in the process. Biologist Stefano Piraino thinks that they’re able to “switch off some genes and switch on [others], reactivating genetic programs that were used in earlier stages of the life cycle.” However, researchers have dismissed ideas that the species could hold the key to anti-aging drugs—and maybe that’s for the best. If the Turritopsis can spread this rapidly through the world’s oceans, then I don’t think immortality would very healthy for humans.
So I was fiddling between Google and MapCrunch and do you know what I found?
Do you know who that is? Yep, that’s Mary Poppins.
Do you know where that is? Yep, that’s Cardiff. Specifically, that’s outside the Roald Dahl Plass.
Do you know what the Roald Dahl Plass is? Yep, the roof of Torchwood.
Do you know why Torchwood is there? Yep, that’s because of the rift in Cardiff, specifically that rift for a specific reason.
Do you know where the Doctor re-fuels the TARDIS?
So tumblr was right.

At first there didn’t seem to be anything unusual about the man who, in 2010, reported to a Verona, Italy emergency room. He was short of breath, sweating, and had low blood pressure – cardiovascular trouble, no doubt. E.R. doctors see similar symptoms all the time.
But this man was very different indeed. He had two hearts.
“We haven’t ever seen anything similar to this case before,” Dr. Giacomo Mugnai said in an email.
It turned out that a few years earlier, the man had undergone a procedure known as a heterotopic heart transplant. Unlike an orthotopic transplant, in which one organ is removed and another put in its place, a heterotopic transplant pairs a new organ with a diseased one.
“We see this in cardiac patients or kidney patients, sometimes,” explained Dr. Rade Vukmir, professor of emergency medicine at Temple University and a spokesman for the American College of Emergency Physicians. “Surgeons might leave a kidney in place if it’s too much trouble to take out, or if there is hope for recovery of a kidney, or a heart, after a period of time” of being helped by the new organ.
In the case of the ailing Italian, reported in the Annals of Emergency Medicine, the transplant team had mated his new heart with his malfunctioning old one. Chambers and blood vessels of the two hearts were married so that the new heart could support the old one….
…This sonic screwdriver is able to detect and visualize these invisible problems by bouncing sound off the plane’s surface and, well, it’s like that hammer test, but a heck of a lot more precise. The company hopes to ready the device for regular use by the end of next year.
so many things i want.
That moment when you stop at Cardiff and accidentally stumble across a Doctor Who set. Oh, lawl, silly me.
So this theatre I walked by today had what looked to be some kind of Gallifreyan message on its windows (no doubt left there by River Song)
