Scientists Offer 'Overwhelming' Evidence Terran Life Began in Space 556

An anonymous reader writes "Using data from recent comet-probing space missions, British scientists are reporting today that the odds of life starting on Earth rather than inside a comet are one trillion trillion (10 to the power of 24) to one against. That is, we're not originally from around here. Radiation in comets could keep water in liquid form for millions of years, they say, which along with the clay and organic molecules found on-board would provide an ideal incubator. 'Professor Wickramasinghe said: "The findings of the comet missions, which surprised many, strengthen the argument for panspermia. We now have a mechanism for how it could have happened. All the necessary elements - clay, organic molecules and water - are there. The longer time scale and the greater mass of comets make it overwhelmingly more likely that life began in space than on earth."'" jamie points out that the author of this paper has many 'fringe' theories. Your mileage may vary.

US Opposes G8 Climate Proposals 845

elrond writes "The US appears to have summarily rejected draft proposals for G8 members that would have agreed to tougher measures for controlling greenhouse gas emissions. The BBC reports that leaked documents have indicated the positions of the various world powers, from the timetable-setting of Germany to the US's intractable stance. Red ink comments on the documents hint at the US's irritation: 'The US still has serious, fundamental concerns about this draft statement. The treatment of climate change runs counter to our overall position and crosses 'multiple red lines' in terms of what we simply cannot agree to ... We have tried to tread lightly but there is only so far we can go given our fundamental opposition to the German position.'"

Some Soft Drinks May Damage Your DNA 643

Parallax Blue writes "The Independent is reporting new findings that indicate a common additive called sodium benzoate, found in soft drinks such as Fanta and Pepsi Max among others, has the ability to switch off vital parts of DNA in a cell's mitochondria. From the article: 'The mitochondria consumes the oxygen to give you energy and if you damage it — as happens in a number of diseased states — then the cell starts to malfunction very seriously. And there is a whole array of diseases that are now being tied to damage to this DNA — Parkinson's and quite a lot of neuro-degenerative diseases, but above all the whole process of aging.' European Union MPs are now calling for an urgent investigation in the wake of these alarming new findings."

Creationism Museum Opening in Kentucky 1166

Noel Linback writes "A new creationism-espousing museum is opening in the state of Kentucky. According to a New York Times article the museum depicts humans and dinosaurs living together in traditional 'diorama' style exhibit. 'Whether you are willing to grant the premises of this museum almost becomes irrelevant as you are drawn into its mixture of spectacle and narrative. Its 60,000 square feet of exhibits are often stunningly designed by Patrick Marsh, who, like the entire museum staff, declares adherence to the ministry's views; he evidently also knows the lure of secular sensations, since he designed the Jaws and King Kong attractions at Universal Studios in Florida. For the skeptic the wonder is at a strange universe shaped by elaborate arguments, strong convictions and intermittent invocations of scientific principle. For the believer, it seems, this museum provides a kind of relief: Finally the world is being shown as it really is, without the distortions of secularism and natural selection. '"

BBC Kicked out of School Over Wi-Fi Scaremongering 279

h2g2bob writes "Ben Goldacre reports that the BBC Panorama team, while scaremongering over the dangers of Wi-fi, were told to leave the school because even the kids could see it was dumb: 'When the children saw Alasdair's Powerwatch website, and the excellent picture of the insulating mesh beekeeper hat that he sells (£27) to protect your head from excess microwave exposure, they were astonished and outraged. Panorama were calmly expelled from the school.' Should we be pleased that the kids can out-think TV producers?"

A Snapshot of the Universe 3 Trillion Years From Now 197

ultracool wrote with a link to a Science Daily article that requires that you think long term. Really long term. Case Western Reserve University physicists are theorizing that trillions of years from now the universe will become 'static'. Essentially, the information that we use to gauge our Galaxy's position in the universe will have moved beyond the 'visible horizon. "What remains will be 'an island universe' made from the Milky Way and its nearby galactic Local Group neighbors in an overwhelmingly dark void ... The researchers followed up that discussion with one tracking early elements like helium and deuterium produced in the Big Bang. They predict systems that allow us to detect primordial deuterium will be dispersed throughout the universe to become undetectable, while helium in concentrations of approximately 25 percent at the Big Bang will become indiscernible as stars will produce far more helium in the course of their lives to cloud the origins of the early universe."

Submission + - Open Source Drug Regulation?

An anonymous reader writes: Forbes has a story comparing the safety controversy over the diabetes drug Avandia to the open-source movement. Criticism has been leveled by cardiologist Steven Nissen who used Google to find clinical studies on Glaxo's website, then reanalyzed them.

From the article:
"Both houses of Congress are expected to pass laws that tweak the way the FDA monitors the safety of new medicines after they are approved. Many of the most radical changes, like a proposal to restrict TV ads and a push from Grassley to set up a separate FDA division to monitor side effects, didn't make it into the Senate version. But the bill would compel drug firms to make all of their data available on public Web sites. That, in turn, would let academic watchdogs like Nissen troll for side effects more easily.

It's an open source approach to drug safety."

Did an Exploding Comet Doom Early Americans? 89

New Scientist outlines a new theory on the demise of the Clovis people in the southwest US over 10,000 years ago. A group of 25 researchers speculates that a comet exploded over ice-covered Canada 12,900 years ago and triggered a firestorm across North America that not only wiped out the Clovis people but also forced a number of large land mammals into extinciton and kicked off the Younger Dryas climate change. However, geologists are pretty conservative folks, according to the article, and some of them are not buying it.

Submission + - Checkers has been Solved

r55man writes: "The Chinook project recently announced that checkers has been solved. Perfect play from both sides results in a draw. From their website:

On May 8, 2007, we were pleased to announce that checkers is now solved. From the standard starting position, Black (who moves first) is guaranteed a draw with perfect play. White (moving second) is also guaranteed a draw, regardless of what Black plays as the opening move. Checkers is the largest game that has been solved to date.

Submission + - Polar ocean absorbing less CO2 than expected.

je ne sais quoi writes: The BBC is reporting on a study by an international team due out in Science magazine (subscription required). Their finding is that the Southern ocean may be absorbing less CO2 now than 25 years ago.

Why is this important? About half of atmospheric CO2 emissions go into the carbon sinks such as the Southern ocean and this ocean represents about 15% of the global carbon sinks. The interaction of CO2 with the ocean is pretty complex, but on the time scale of the study, there are two main competing effects: the first is that as oceans warm, they absorb less CO2. (This is why your beer is more fizzy when its warm, it can hold less CO2.) The second is that as more CO2 is absorbed into the ocean, more of it converts to bicarbonate (which incidentally, increases of the acidity of the oceans which will also change CO2 solubility).

Previously, it was known that eventually the first factor would win out, temperature would eventually limit CO2 absorption, but they thought it would happen 40 years from now. If this data is correct, it's happening now.

26 Common Climate Myths Debunked 998

holy_calamity writes to mention that New Scientist is revealing the truth behind the '26 most common climate myths' used to muddy the waters in this ongoing heated debate. "Our planet's climate is anything but simple. All kinds of factors influence it, from massive events on the Sun to the growth of microscopic creatures in the oceans, and there are subtle interactions between many of these factors. Yet despite all the complexities, a firm and ever-growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences."

Submission + - Our Solar System is Perpendicular to Milky Way

eldavojohn writes: "Recent data from the Voyager I & II space craft has revealed that our galaxy is passing through the Milky Way at an angle between 60 and 90 degrees to the disc shape our galaxy forms. From the article, "The findings, detailed in the May 11 issue of the journal Science, suggest the magnetic field in the galactic environment surrounding our solar system is pitched at a sharp angle and not oriented parallel to the plane of the Milky Way as previously thought." The paper in Science explains more about the observations of the magnetic field that exists just outside our solar system and the motivation for drawing this conclusion from it. Definitely revolutionizes the way we thought about our solar system in our galaxy."

Bill To Outlaw Genetic Discrimination In US 353

fatduck sends us a brief note from New Scientist about the overwhelming passage in the US House of Representatives of the Genetic Information Nondiscrimination Act. As written, the bill would prohibit insurance companies from charging higher rates, and employers from discriminating in hiring, based on the results of genetic tests. A Boston Globe editorial notes that the bill has been held up in the Senate by the action of a single senator, who has an (outdated) objection based on his anti-abortion stance. President Bush has said he will sign the bill if it reaches his desk.
