End of term clean-up.

Today I'm in my office to clean up and get ready for the summer term course I'll be teaching in July. I've got a stack of papers to go through, clear off my desk and dump in the shred bin. But, I've also got a collection of science news stories which have been cluttering up my browser. In the spirit of clean-up, here's a small link dump:

• PhD student in Canada is studying the psychology of earworms. (What's an earworm?)
• Another Canadian psychologist has examined how Rembrandt draws viewers into his paintings.
• An engineering student in England has adapted a bike to pump water in Guatemala.
• NASA's Mars Reconnaissance Orbiter flew over the Phoenix lander and may have imaged the damage to the lander, explaining why it never woke up after the Martian winter. 
• Infrared image of nebula from the WISE telescope looks like a pair of hearts situated next to each other in space.
• Want to go to Neptune and come back in 5 years?  It will only cost you $4 trillion. (More links at bottom of that page.)
• Possibly the most adorably unfortunate misspelling of hadron ever.  Let's hope this kid never loses his interest in science. 
• Something hit Jupiter last year, and amateur astronomers saw it first.
• In May, The Big Picture featured a round-up of really great images of Saturn and its moons.

I think that is all the links I've been saving up. You can always see my shared google reader links, even if you aren't following me.

Back to clearing the desk.
