A rehash of the available data has narrowed the search for the Higgs particle.

A rehash of the available data has narrowed the search for the Higgs particle.

Taken together with data from the other detector, ATLAS, Higgs overall signal now unofficially stands at about 4.3σ. In other words, if statistics are to be believed, then this signal has about a 99.996% chance of being right.

It all sounds very convincing, but don’t get too excited, because the fact is that statistical coincidences happen every day. Over at Cosmic Variance, Sean Carroll points out that there is a 3.8σ signal in the Super Bowl coin toss.

All NASA funding for the European ExoMars mission appears to have been cut by the Obama administration.

9:13 pm

All NASA funding for ESA’s unmanned ExoMars mission appears to have been cut by the Obama administration.

A public announcement by Nasa of its withdrawal from the ExoMars programme, as it is known in Europe, will probably come once President Obama’s 2013 Federal Budget Request is submitted. This request, expected in the coming days, will give the US space agency a much clearer view of how much money it has to implement its various projects. “The Americans have indicated that the possibility of them participating is now low – very low. It’s highly unlikely,” said Alvaro Gimenez, Esa’s director of science.

Though this story doesn’t confirm the earlier rumors that the Obama administration was going to eliminate the entire NASA planetary program, it sure lends those rumors further weight. However, the new budget should be released any day now, when we will finally find out.

All the arguments used against Israel for taking a preemptive strike against a nuclear Iran are wrong.

2:43 pm

All the arguments used to convince Israel not to take a preemptive strike against a nuclear Iran are wrong.

We must also add these words by Iran’s “Supreme Leader of the Islamic Revolution” Ayatollah Khamenei:

The Zionist regime is a real cancerous tumor that should be cut and will be cut.

Like Hitler, who in Mein Kampf told the world exactly how he intended to exterminate the Jews years before he had power, the Iranians have been quite blunt about what they intend to do once they have atomic weapons. This time, we should take them at their word, and stop them before they can do it. And since the U.S. isn’t likely to do it, the Israelis should.

Unconfirmed reports in the Russian press today claim that the drilling team in Antarctica has successfully reached Lake Vostok more than two miles under the icecap.

Unconfirmed reports in the Russian press today claimed that the drilling team in Antarctica has successfully reached Lake Vostok, more than two miles under the icecap.

No results yet. And since the story above spends more time talking about old silly stories about a hidden NAZI hideout in Antarctica than it does the Russian science effort there it should be taken with a grain of salt.

Mars Express has found more evidence that Mars once had oceans.

Mars Express has found more evidence that Mars once had oceans.

Two oceans have been proposed: 4 billion years ago, when warmer conditions prevailed, and also 3 billion years ago when subsurface ice melted following a large impact, creating outflow channels that drained the water into areas of low elevation.

“MARSIS penetrates deep into the ground, revealing the first 60–80 metres of the planet’s subsurface,” says Wlodek Kofman, leader of the radar team at IPAG. “Throughout all of this depth, we see the evidence for sedimentary material and ice.” The sediments revealed by MARSIS are areas of low radar reflectivity. Such sediments are typically low-density granular materials that have been eroded away by water and carried to their final destination.

This later ocean would however have been temporary. Within a million years or less, Dr Mouginot estimates, the water would have either frozen back in place and been preserved underground again, or turned into vapour and lifted gradually into the atmosphere. “I don’t think it could have stayed as an ocean long enough for life to form.”

Obamacare vs. the Catholics

1:41 am

Religious liberty is such an inconvenient thing: Obamacare vs. the Catholics.

And then there’s this: An affront Catholics agree on.

And this: The Assembly of Canonical Orthodox Bishops of North and Central America has announced its unanimous support of the Catholic Church and opposition to the Obama Administration over the new Obamacare regulations.

My question is this: if Obama should back down before the election and cancel these odious regulations, will the liberal church leaders forget the whole thing and support him again, or will they finally wake up and see him for what he is: an arrogant power-hungry politician eager to force his will on everyone, regardless of their beliefs?

More than 6,000 people submitted their applications to NASA last week to become astronauts, the most since 1978.

More than 6,000 people submitted their applications to NASA last week to become astronauts, the most since 1978.

Once again, this is strong evidence that Americans want to explore space, and that there is a market out there for private enterprise to cash in on. NASA doesn’t even have a way to put any of these astronauts into space, and yet, people come out in droves to apply.

For the last five days there has been no contact with the Russian scientists drilling down more than two miles to Lake Vostok in Antarctica.

Updated and bumped: Six days now, and no word.

Fact meets science fiction: For the last five days there has been no contact with the Russian scientists drilling down more than two miles to Lake Vostok in Antarctica.

The team from Russia’s Arctic and Antarctic Research Institute (AARI) have been drilling for weeks in an effort to reach isolated Lake Vostok, a vast, dark body of water hidden 13,000 ft. below the ice sheet’s surface. The lake hasn’t been exposed to air in more than 20 million years.

Priscu said there was no way to get in touch with the team — and the already cold weather is set to plunge, as Antarctica’s summer season ends and winter sets in. “Temps are dropping below -40 Celsius [-40 degrees Fahrenheit] and they have only a week or so left before they have to winterize the station,” he said. “I can only imagine what things must be like at Vostok Station this week.”

R.I.P: Roger Boisjoly, 73, has died.

R.I.P: Roger Boisjoly, 73, has died.

Boisjoly was the engineer who in 1985 warned NASA about the danger of launching the shuttle in cold weather, that the solid rocket booster’s joints might not seal correctly under those conditions, thereby causing a catastrophic failure. Sadly, he was ignored, even ostracized, and on January 28, 1986, Challenger broke apart 74 seconds after launch, killing seven astronauts.

Virgin Galactic hopes to begin the first powered flight tests of SpaceShipTwo this coming summer.

10:02 pm

Getting close: Virgin Galactic hopes to begin the first powered flight tests of SpaceShipTwo this coming summer.

“Over the next few months we’re integrating parts and pieces of the hybrid rocket motor into the SpaceShipTwo airframe, completing ground testing of the rocket motor, and then [will] try and start powered flight over the summer,” [chief executive officer and president George] Whitesides told SPACE.com. Those rocket-powered flights, he said, will continue for some period of time. Whitesides said it looks possible “to get up to space altitude by the end of the year, if all goes well.”

The company is also building a second WhiteKnightTwo and SpaceShipTwo,

Another superEarth has been found orbiting a star in the habitable zone.

5:31 pm

Another superEarth has been found orbiting a star in the habitable zone.

An M-class dwarf star called GJ 667C, which is 22 light-years away from Earth, had previously been observed to have a super-Earth (called GJ 667Cb) that orbited the star in only 7.2 days, making it too close to the star, and thus too hot, to support life.

The study started with the aim of learning more about the orbit of GJ 667Cb. But the research team found a clear signal of a new planet (GJ 667Cc) with an orbital period of 28.15 days and a minimum mass of 4.5 times that of Earth.

Though the planet is much closer to its star than the Earth, the star itself is much smaller and dimmer, so overall the planet gets about the same amount of energy as the Earth.
