"Soon after the instruments opened their doors, the Sun began performing for SDO with this beautiful prominence eruption. This AIA data is from March 30, 2010, showing a wavelength band that is centered around 304 �. This extreme ultraviolet emission line is from singly ionized Helium, or He II, and corresponds to a temperature of approx. 50,000 degrees Celsius."

A volcano eruption (Eyjafjallajökull) in Iceland has been causing a lot of havoc in the Northern Hemisphere in the past week, especially in Europe. It has grounded flights all across the continent and many people are stuck and can't get back home or to their destination. The interesting thing is that flights can get off in the main Iceland airports, since the ash is being carried south and the main airport for example in Keflavik is located more to the north. The last time the volcano erupted in the 19th century, it continued on erupting for more than two years from 1821 to 1823.

Antarctica is an interesting continent. Once, millions of years ago, it actually had a lush landscape. However now most of it is a frozen wasteland of ice. Under the ice is a different story though. There are lakes and rivers flowing and they might even contain life.
"Antarctica's buried lakes are connected by a network of rivers moving water far beneath the surface, say UK scientists. It was thought the sub-glacial lakes had been completely sealed for millions of years, enabling unique species to evolve in them. Writing in the journal Nature, experts say international plans to drill into the lakes may now have to be reviewed. Any attempts to drill into one body of water risks contaminating others.
"What this paper shows is that not only could you contaminate a lake, you could contaminate the whole drainage system," lead author Duncan Wingham, of University College London, told the BBC News website."

The first round was a computer round, where you did 3 tests: a test on EU knowledge, verbal test and a numerical test. (in your main foreign language: English, French, German) Then the second round is a grueling 6 hour marathon, where you do written tests on your specialty. So if you're applying as an economist, you do the test on economics. You do a test on economics theory and then write essays on economics topis, one in your foreign language and one in your native language. The third round is an oral interview with a panel of interviewers and they can ask you all kinds of questions from basic CV and personal history questions, to questions about the EU or economics theory (if applying as an economist).
And then if you pass that then you are on the reserve list. So by passing the tests it's all smooth sailing to a job? Not exactly, you can be on the reserve list for years and aren't guaranteed a job and even if they call you for an interview, you still have to compete for the position with a large group of other applicants.
They are now reforming this system and are going to set up a new system. Hopefully they will still renew the old reserve lists as there are still many people on them.

The first Mickey Mouse cartoon with sound was Steamboat Willie, which appeared on 18 November, 1928.
And the very first cartoon where Mickey Mouse actually spoke was Karnival Kid from 1929.

And a new find in Siberia. Supposedly another human species co-existed with modern humans just a few tens of thousands of years ago.
""Scientists have identified a previously unknown type of ancient human through analysis of DNA from a finger bone unearthed in a Siberian cave.
The extinct "hominin" (human-like creature) lived in Central Asia between 48,000 and 30,000 years ago.
An international team has sequenced genetic material from the fossil showing that it is distinct from that of Neanderthals and modern humans.
Details of the find, dubbed "X-woman", have been published in Nature journal.
Ornaments were found in the same ground layer as the finger bone, including a bracelet.""

"New evidence has emerged to show that an extinct, diminutive people known as "hobbits" from the Indonesian island of Flores belonged to a new species of primitive humans and not modern pygmies.
The 1 metre (3ft) tall, 30kg (65lb) people are believed to have roamed the Indonesian island of Flores, perhaps up to 8,000 years ago.
The new anatomical evidence, reported in today's Nature magazine, is based on the examination of lower limbs and especially an almost complete left foot and parts of the right. It shows that the species walked upright, like other known hominids, and there were five toes, as in other primates, but the big toe was stubby, more like a chimp's.
Controversy has been rife ever since the discovery of the species, formally named Homo floresiensis, was announced in 2004. The single skull was unusually small, indicating its brain was no bigger than a chimpanzee's. Some scientists argued that the species was nothing more than modern pygmy humans deformed by genetic or pathological disorders.
But in light of the new evidence, scientists believe it is unlikely that traits such as the small brain, primitive shoulders and wrists as previously reported "were simply a consequence of 'island dwarfing'.""

The Large Hadron Collider near Geneva, Switzerland does some pretty cool experiments. They recently had a webcast of one of their experiments. (30 March 2010)
"The first high-energy collisions were achieved at 13.06 today at all four points of the LHC ring. Collisions occurred after a few attempts at injecting and ramping beams in the morning. Before the collisions, there was a mixture of excitement, expectation, fear and apprehension in the CERN Control Centre. Nobody had ever attempted to make two proton beams collide at 3.5 TeV before. Only Nature produces collisions like this routinely, in the processes that yield cosmic radiation, but in a way that makes it very difficult to extract meaningful data."
