A publicity campaign has been launched to highlight details of new laws allowing the UK's first "gay marriages". The BBC News website asks two couples what the law means to them.

Scientists will meet this weekend to launch an action plan aimed at stemming the global decline in amphibians.

About a third of frog, toad and salamander species are facing extinction; threats include fungal disease, pollution and habitat loss.

One researcher has even proposed a way for life to survive on the giant Saturnian satellite. It is too cold for organisms to survive on the surface of Titan, where temperatures are about -178C (-289F).

But David Grinspoon of the Southwest Research Institute says organisms could occupy specific niches, such as hot springs. They could use acetylene, in reaction with hydrogen gas, to release enough energy to power metabolism, and possibly to heat their environments.

"We are all here in China that represents quite a lot of opportunities, not only on the business side, but also on the social side," Yang said.

"We look at our users' interests, without our users we don't have business."

At the same time, it was essential that Yahoo employees abide by local laws as well, he added.

"I would not put our employees at risk in anyway, shape or form and when it comes to issues such as seeking user information we have a very clear cut set of rules."

"The government of any country has engaged with us through legal documentation or legal procedures, we get a lot of those every day around the world."

On the heels of Yahoo helping China bust journalist Shi Tao, Jerry Yang is in China taking part in the Internet Summit being thrown by Alibaba. Who thinks they would have been welcome there if they didn't hand over the information? I don't.. And I'm not just talking about the summit.

Bill Clinton is also attending.

"In China, I think that so far the political system and restraint on political speech in the Internet has not seemed to have any adverse commercial consequences," Clinton said.

"It will be interesting to see whether that is true of the future.

"In America, the Internet is this wild cauldron of dissenting voices, we have now whole different media over the Internet with all the blog sites in America," he said.

Clinton nails it. Its all about the market. Its the Chinese internal market that must put the pressure on the Chinese government. An internal approach is better than an external one. In China's eyes, any pressure from outside to change their approach to speech would be seen in a light akin to terrorism. The Chinese citizens need to be the ones to fly the Internet into Beijing. To stretch the analogy for all its worth, the pilots cannot be Chinese trained in America for their actions to take hold in the society. It must come from within. They can do it based on our ideology, but lets not be so blatant about it as to put it in the context of a state based attack. Put your faith in freedom and people. In this case, the Chinese people.

The next person standing in front of a tank will be holding a laptop with Wifi.

Americans spend $5,267 per capita on health care every year, almost two and half times the industrialized world’s median of $2,193; the extra spending comes to hundreds of billions of dollars a year. What does that extra spending buy us? Americans have fewer doctors per capita than most Western countries. We go to the doctor less than people in other Western countries. We get admitted to the hospital less frequently than people in other Western countries. We are less satisfied with our health care than our counterparts in other countries. American life expectancy is lower than the Western average. Childhood-immunization rates in the United States are lower than average. Infant-mortality rates are in the nineteenth percentile of industrialized nations

The counter point to this perspective usually consists of "sick people aren't my problem" or "wealthy people get more convenient healthcare in the US then in Canada." I am constantly amazed to talk to Americans who actually beleive that Canada is a socialist country. This spin is the product of Rush Limbaugh's rantings during the Clinton years. "Socialism is bad, right? Thats what the communists did, and they were evil!"

The American healthcare system is both heavily regulated and wealth redistributed. Its just as socialist as anyone else's healthcare system. But it has the additional feature of generating a class of people with serious medical problems who are too sick to work and therefore don't get to participate in the wealth redistribution. Oh, and its more convenient for the wealthy because they never have to wait in line behind someone with a more serious problem unless they are at an ER. And its a hell of a lot more expensive.

Gripping onto a ideology for ideology's sake while it is literally killing you seems the very definition of irrational behavior. On the issue the United States is like the last guy back in the hood in New Orleans, sitting on his couch with a foot of standing water in his living room, slowly succumbing to the E.Coli because its his damn town and he'll be damned if he is gunna leave, even after everyone else is long gone...

Sounds like the Administration wants to get up off the couch and go for a swim. Don't worry about Europe hating us. If we keep going down this path they'll be laughing at us instead.

Edinburgh scientists have made a small blob of liquid move across a surface by shining a light in front of it.

It may not sound like much but the molecular engineering that went into this feat is said to be a step forward in the emerging area of nanotechnology.

The world's first pure nerve stem cells made from human embryonic stem cells has been created by scientists at the Universities of Edinburgh and Milan.

It is hoped the newly-created cells will eventually help scientists find new treatments for diseases such as Parkinson's and Alzheimer's.

Science and technology have powered huge leaps in understanding but our biggest challenges lie ahead.

The science of complexity is perhaps the greatest challenge of all, Astronomer Royal Sir Martin Rees believes.

The biggest conundrum is humanity and how we came to be, he told the Technology, Entertainment and Design (TED) conference in Oxford.

The cosmologist said that in the 21st Century science has changed the world faster than ever before and in many new ways.

quote{ WEST LAFAYETTE, Ind., July. 12 (AScribe Newswire) -- Researchers at Purdue University have new evidence supporting earlier findings by other scientists who designed an inexpensive "tabletop" device that uses sound waves to produce nuclear fusion reactions.

The technology, in theory, could lead to a new source of clean energy and a host of portable detectors and other applications.

The new findings were detailed in a peer-reviewed paper appearing in the May issue of the journal Nuclear Engineering and Design. The paper was written by Yiban Xu, a post-doctoral research associate in the School of Nuclear Engineering, and Adam Butt, a graduate research assistant in both nuclear engineering and the School of Aeronautics and Astronautics.

A key component of the experiment was a glass test chamber about the size of two coffee mugs filled with a liquid called deuterated acetone, which contains a form of hydrogen known as deuterium, or heavy hydrogen. The researchers exposed the test chamber to subatomic particles called neutrons and then bombarded the liquid with a specific frequency of ultrasound, which caused cavities to form into tiny bubbles. The bubbles then expanded to a much larger size before imploding, apparently with enough force to cause thermonuclear fusion reactions.

Fusion reactions emit neutrons that fall within a specific energy range of 2.5 mega-electron volts, which was the level of energy seen in neutrons produced in the experiment. The experiments also yielded a radioactive material called tritium, which is another product of fusion, Xu and Butt said.

Last Monday, when I wrote here that it was going to be quite a week, I didn't know the half of it.

This is the voice of one the most respected journalists in the BBC and I urge everyone at Memestreams to read the article. This is the voice of the country I love.
