Grail shattered on moon

Summary: The GRAIL mission has officially ended as its two satellites, Ebb and Flow, has been commanded to crash into the surface of the moon. It was decided to direct a crash landing when the fuel ran out rather than wait for an eventual, unpredictable fall so as not to destroy any of the historic landing sites like the Apollo site. (Imagine if a satellite fell and knocked over the American flag!)
Most of the data from these two satellites has not been fully analysed yet, but scientists do know that the data from these two provide the most detailed map of the surface of the moon that we have to date. As usual, for for details, check out the original article.

Lake drilling halted

Summary: Drilling in Antarctica that had begun early last week had to be halted on Saturday due to a failure in the backup boiler. The primary boiler had already failed with the same issue. Thankfully there is enough hit water to keep the drill from freezing over.

The objective is to drill through the ice to the lake underneath and analyse the water brought up to see if there is life down there.

Geminid Meteor Shower Tonight!

The biggest and best meteor shower of the year is tonight!! (Clearly the Universe is celebrating the release of The Hobbit). For info about the shower check out http://www.meteorwatch.org/ where you can find details and pictures from other sky watchers. Furthermore, it is a new moon tonight so they sky should be especially dark. Happy sky watching!

Dark matter

If you do not understand Dark Matter, here is a good blog post comparing the universe to making a cake.

Wishy-washy Higgs

Summary: The inconsistencies and weird things in the data that lead scientists to announce the discovery of a new particle back in July, curiously still remain. It seems to be a difference in measurement that makes the difference.

There have also been hints of other weird science occurring that frankly does not make much sense to me, but something about particles flattening and gaining gluons as they reach the speed of light, possibly being observed.

Either way, next week the LHC will shift into a new phase before being shut down for upgrading at the beginning of 2013. Not to worry though, they still have tons of data to analyze.

Decay

Summary: Students and scientists at CERN have completed their zombie movie! After three long years of working on it you can watch it at the link below. The premise is that some engineers were down in the tunnels of the LHC when some radiation leaked and turned them into zombies. Now the remaining members must figure out what caused it before they are also dead meat.
To mock Hollywood's atrocious science, they too purposefully made ludicrous claims, only in this case, the actors (also students) kept trying to fix the errors and had to be reminded that it was wrong on purpose.
 I'll update this post after I watch it with a spoiler-free review.

New galaxies examined

Summary: The Hubble telescope has been used to look again in the area of the Hubble Deep Field and has found 7 new galaxies, one of which may be the most distant galaxy observed. We can tell by the redshift. (The further away a galaxy is, the faster it is moving away from us. Because it is moving so fast, the light gets shifted a measurable amount. Further away=greater redshift.)

Multiple Universe Theories

For those of you interested in more than just antimatter and enjoy bizarre theories, here is a link to an article about some theories for multiple universes. Personally, I am hoping that there are multiple universes, but I doubt that we would be able to prove it in any way. But the thought of it is mind-blowing.
And if you don't know about the multiple universe theory, take a look at let it amaze you.

Ice on Mercury!!!

Summary: At last, a planet close to home that we can travel to and ice skate on! But actually, the Messenger satellite has discovered that craters at the poles hold ice. The exciting thing is that because of this evidence, all strongly held theories about the formation of Mercury are incorrect. Now scientists will get to rewrite the history of the planet and maybe other inner planets like it.

Oversized Black Hole

Summary: Scientists have found a enormous black hole in the middle of a relatively small galaxy. It's been calculated that the black hole accounts for about 15% of the galaxies mass. This is way more than is typical. Scientist are guessing that it was formed a long time ago and then nothing else really started to form. Check out the details below.

Rogue Planet

Summary: Scientists working at the Very Large Telescope Array have found a rogue planet! This means it is not orbiting any star. It appears, however, to be drifting with another group of celestial objects. Based on the ages of those objects, it is predicted that the planet was formed between 50 and 120 million years ago. Based on this, they have also guessed that the planet is about 400 degrees Celsius and its mass is between 4-7 times that of Jupiter.
It is unsure whether the planet was a failed star formation or whether it was cast off from its original planetary system and doomed to wander alone.

New Method of Measuring Dark Energy

Summary: I'm not sure I understand this one. Here's what I understand: there is a new way of measuring the presence of Dark Energy in our universe over time. It involves measuring the scatter of light through hydrogen clouds. The way quasars scatter through those clouds is very specific so it can be measured. It has helped to confirm that the early universe the Gravitational force dominated, causing a deceleration in the expansion of the universe, but then Dark Energy took over and the universe began the phase of rapid expansion we are currently in.
This new method is being employed by the members of BOSS team in the US.

Another blow struck at the Standard Model

Summary: The scientists at the LHCb have observed a Bs meson decay into three muons, a decay possibility that is extremely rare. This puts a hole in the Supersymmetry model which attempts to explain some if the inconsistencies in the standard model. As usual, this is not conclusive evidence, but it seems to indicate that our universe is more complicated than a standard model can predict.

Space Internet!

Summary: Internet has become a crucial part of life, especially when it comes to communicating over extremely long distances. But our beloved Internet has been lacking in space. Don't fret though, you future astronauts! NASA and ESA have been working on creating an interplanetary net. While they probably aren't too concerned about whether you will be able to watch YouTube or not, it will allow them better control over their rovers.
The way it is now, each robot is controlled separately and if there is an error in sending data, it it lost forever. This new space Internet hopes to remedy that. It is in testing phase with astronauts on the ISS successfully controlling a robot in Germany. I honestly do not understand how it works but the BBC explains it well for anyone who knows computers well.

Martian Hula party

After examining its first sample of Martian soil, Curiosity's scientists have noticed that the soil strongly resembles the soil on Hawaii. They've said it was basaltic like the ground near volcanos in Hawaii.
Curiosity also analysed the soil further by shooting X-rays at it. This is a technique well known back here on Earth that allows scientists to learn the chemical make up of a sample by the light it emits.
As always, check out the original article for further details and don't hesitate to ask me any questions you may have.

Chills down my spine

Summary: it may not directly relate to science, but great scientists. While stranded in Antarctica during the 9 months of winter, British scientists have decided to make a horror film. Because of their long winter, scientists pick up and refine hobbies to keep themselves busy. The film, called "South of Sanity," features 14 scientists being stalked by a killer. One of the main problems was actors (other scientists) getting slight cases of hypothermia because of extended periods if outside and laying in the snow being dead bodies. Unfortunately, this resulted in dead bodies that shivered.
The film will get its premiere in Aviemore on 31 October. (I have no clue where that is.)

Strange rock on Mars

Summary: Curiosity has found a peculiar rock near to its landing sight. While not an entirely new type of rock, it is not a type that was predicted to be in that area. The rock, named Jake Matijevic after a recently deceased scientist, is similar to the types of rocks found near volcanoes on the islands of Hawaii.
"Jake Matijevic was found to be high in elements consistent with the mineral feldspar, such as sodium and potassium, and low in elements such as magnesium and iron."
Further studies will be done with this rock in hopes of learning more about the history of the Gale Crater and Mars as a whole.

Cracks in the Standard Model?

Summary: "Recently analyzed data from the BaBar experiment show that one type of particle decay happens more often than predicted by the Standard Model.  This excess, seen with a “3.4 sigma” level of certainty, is not enough to claim a definitive break from the accepted theory, but it is a sign that something could well be amiss."
Basically, particles aren't decaying into different particles with the same frequency as predicted. If validated it could point to the Higgs particle having a charge and there would be a huge ripple effect seen in the Standard Model.

Colossal telescope given go-ahead

Summary: The European Extremely Large Telescope (E-ELT) is given the go ahead to be built. It will have a primary mirror some 40m in diameter, and will be built on top of a mountain in Chile. When completed it will be the largest optical telescope in the world. It will see in visible and near-infared. It will hopefully uncover some of the mysteries surrounding dark energy.

Majorana particle

Summary: A particle that is the opposite of itself (it does not have an antimatter equivalent) was theorized by the crazy scientist Ettore Majorana. After 75 years it seems as if Dutch scientists may have found this mysterious particle that could hold a key to learning more about dark matter.

New data from the Tev

After sifting through more data from the Tevatron, there are hints of a particle between 115 and 135 GeV with a certainty of 2.2 sigma. (Not enough to call it a discovery.) The LHC has found a suggestive "bump" as well at the same mass even though the experiments conducted to get the data were extremely different.

One in a Billion

LHCb, an experiment within the LHC, has further proven that the standard model is correct. (Much to my disappointment.) They have watched B mesons to determine how many decay in which manner. Their data lined up with what the standard model dictated so it seems as if the standard model is gaining validity.

New antimatter development

Data from the Tevatron has further solidified unexpected data from the LHC regarding how particles decay. It is not quite at four sigmas of certainty but it is enough to make scientists think about the implications.

Updates on Faster than Light Neutrinos

It turns out the particles may not have exceeded the universal speed limit. After further tests it was determined that a glitch in the GPS synchronising may have accounted for the faster time.

Science Mag: http://news.sciencemag.org/scienceinsider/2012/02/breaking-news-error-undoes-faster.html?ref=hp#.T0U_N0pYVRc.twitter

However later scientists discovered another possible glitch that made the particle appear to travel slower than reality. It is unsure which factor influences the recorded time more. As with most of science, more tests will be needed.
