Where Can I Top Up My Gas Meter

virus found in Mexico to eliminate brain tumors


virus found that brain tumors removed
According to the journal Neuroscience, a group of U.S. scientists have discovered a virus that genes play specialized in location and removal of brain tumors in mice. Moreover, and perhaps one of the most important is that these genes left virtually intact healthy tissue and focus their attack exclusively in cancer cells. According
researchers at Yale School of Medicine , the technique to guide the activity of the virus, identified as "vesicular stomatis" could give way to a new treatment for brain cancer in humans. "The study shows that the virus can penetrate the brain where it reaches cells that have migrated away from the main tumor," said Harald Sontheimer, an oncologist at the University of Alabama .
The scientists injected cancer cells in rodents and then grafted the virus. Using fluorescent proteins saw that it has spread leaving behind a trail of dead cancer cells. Scientists said the virus did not attack normal cells or other human cells grafted into the brains of mice.

Scientists locate the "G spot"


A new mystery is about to fade, the enigmatic and controversial release of female sexual satisfaction, the G-spot . And, according to a team of Italian researchers can be located using the ultrasound .
To date, the medicine had not been able to locate this mysterious point, but the scientists say in the magazine New Scientist they found an area of \u200b\u200bthicker tissue among the women reporting orgasms.
Ultrasound was used to measure the size and shape of the tissue beyond the front wall of the vagina, often considered the place where the G spot In the nine women who claimed to have reached the vaginal orgasm, the tissues between the vagina and urethra were on average thicker than in the 11 women.
Dr. Jannini, head of research said: "For the first time, you can determine with a simple, rapid and inexpensive method if a woman has a G spot or not."
Although far from settling the case, Dr. Tim Spector of St. Thomas Hospital London, said that the thicker tissue might actually be part of the clitoris, another extremely sensitive area.
Therefore, still further testing to determine who is right, but instead of worrying about the existence of the mysterious item, the better, says sexologist Petra Boynton, is to relax and not focus or obsess over that area concrete, since all others are ignored.

Microsoft goes to reassure employees to fear of layoffs

Redmond / Sunnyvale (DPA) - Microsoft declined the concerns of employees, who fear that layoffs are made in the event that the software giant to acquire Yahoo.
While a transaction of this size will cause some interference, Microsoft is a growing company and in 2005 took more than 20,000 new people, as one of its managers said in an email they sent to employees.

Yahoo had rejected the offer of 45,000 million dollars on the ground that was below the value of the company. And since been looking for alternatives.

A lamp without plug




February 22, 2008 .- What a pleasure to read da reactions to the announcement of Microsoft. For a few hours yesterday, I thought someone would actually swallow that the company now will open like a flower and to send good vibes across the globe. No is the first time that Microsoft makes an announcement of these features (I'm glad to see that in Europe have the account and they know they are already four) and I fear not the last. Moving a giant of this size is not easy and good will is not enough. We must lead by example. Six months ago the company got caught in the tangle of standards for approving legislation OOXML. In the overnight will not change his whole philosophy.
But the change makes sense, especially for a new Microsoft now believes in the services and advertising, not selling boxes of software. The problem is that its benefits are coming from there, from Windows and Office, and that such programs sell and succeed with a structure that is anything but open. Hopefully this ad to something better.
Microsoft is a company easy to hate and love at the same time. It is incredibly versatile and has great brains inside, able to create amazing tools. It also has a dark side, a special ability to arouse suspicion and a great ambition to control everything related to your software.
Anyway, now that Microsoft uses. Come up with gadgets, with a very green. Specifically with a lamp that works by gravity. Gravia is an unconventional room lamp is no need to plug into the wall. To turn you have to climb a weight from the base to the top of the lamp. The weight began to fall slowly, a mechanism similar to-wall clocks, feeding a collection of LEDs that can shine for four hours before having to lift the weight.
The light generated is not too much-equivalent to a 40 watt bulb, but lamp life is 200 years using an average of eight hours a day. It is what it takes for the LED "fuse."
