Cancer News

The disease that we all know way too well may have just gotten a small kick in the teeth:
British scientists have discovered a "rogue gene" which helps cancer spread around the body and say blocking it with the right kind of drugs could stop many types of the disease in their tracks.

Researchers from the University of East Anglia said their findings could lead within a decade to the development of new medicines to halt a critical late stage of the disease known as metastasis, when cancer cells spread to other parts of the body.

The culprit gene, called WWP2, is an enzymic bonding agent found inside cancer cells, the researchers explained in their study, published in the journal Oncogene Monday.

It attacks and breaks down a naturally-occurring protein in the body which normally prevents cancer cells from spreading.

In tests in the laboratory, the UEA team found that by blocking WWP2, levels of the natural inhibitor protein were boosted and the cancer cells remained dormant.
If there's anything more perfectly sickening and terrifying than how bits of our own bodies can attack us—and travel around to attack us again and again—I don't know what it is. Nor do I want to know.

First Black Holes Created by Black Hole Machine

Just kidding. But the LHC has produced its first collisions - and the black holes will be produced any day now, I'm sure.

Electron Filmed For First Time

Hard to comprehend.

Extremely short flashes of light are necessary to capture an electron in motion. A technology developed within the last few years can generate short pulses of intense laser light, called attosecond pulses, to get the job done.

"It takes about 150 attoseconds for an electron to circle the nucleus of an atom. An attosecond is 10^-18 seconds long, or, expressed in another way: an attosecond is related to a second as a second is related to the age of the universe," said Johan Mauritsson of Lund University in Sweden.


Ow.

Bad Astronomy On the Photo of Mercury

Cool stuff from an astronomy freak.

Do you see that circular feature to the upper right, slightly lighter in color than the surrounding plains? That’s Caloris Basin, the Basin of Heat. It’s called that because when Mercury reaches perihelion, that spot is close to being aimed right at the Sun. It’s one of the worsts spot on Mercury to live, if you’re considering a winter home there. Caloris Basin (formed in some ancient and very large impact) is over 1300 kilometers across — roughly as big as Texas. The mountains ringing it are 2 km high.


Here's a closeup.
