No dark matter yet
Well, the latest CDMS II results have been finally released. The final tally: 2 events with an expected background of 0.8 events. In other words, there is no unequivocal detection of dark matter. The search for dark matter keeps going.

WISE

The Wide Infrared Explorer (WISE) has launched. It will provide an all-sky survey from 3 to 25 microns. Not the highest resolution but it will continue to open our eyes in the infrared.

An old track. I prefer Seu Jorge doing the song in Portuguese and a guitar, but this is the man himself.

Adventures in Piracy

This must qualify as the silly news of the week. Apparently huge celebrations are being held in a small town in Somalia after the release of a Spanish vessel yesterday (sorry only in Spanish). Pirates are back in town with a bounty of 2 million euros and salesmen are trying to sell them everything from 4 x 4 vehicles to authentic DVDs. Pirates in boats, pirate parties, pirates of the Caribbean, pirate politicians. Are we back in the pirate era or maybe it never left?.

Medea
Had a chance to see Medee by the Théâtre des Amandiers - Nanterre. A take on Euripides' Medea that takes place on a refugee camp. Excellent acting and songs. If they ever come to your town make sure to go.

Africa: A Musical Journey (6) - Zimbabwe
We move on to Zimbabwe and Dorothy Masuka. I didn't know she wrote Pata Pata for Miriam Makeba. And to Zimbabweans better times will come soon. Nothing can last forever.
Moon impact

NASA's LCROSS mission has impacted the moon today. The basic idea is to blow up lunar dust, fly through the plume and the check for signs of water. Press conference will start in a few minutes but the good news is that the Moon is safe for now.

Science funding
One of the latest troubling news to come out of the so called global crisis is the 15% reduction in the science budget of Spain for 2010 (You can read more here in Spanish only). Now, everyone on the government side is trying to paint the picture that the cut will not affect current plans for hiring new scientists and projects. But somehow I suspect that a 15% pinch will be felt somewhere (unless this goes to curb 15% in unjustified costs). We cannot pretend that balancing a budget with money shortfalls is an easy task, but there must be something else that can take a bite. Someone estimated that the reduction amounts to 280 million euros per year, that amounts to 4% of the money destined to the military budget, three Ronaldos, or the pension of 6 rich bankers. Fewer bombs/goals/bankers anyone?

Another Ring

Spitzer reports a new ring around Saturn. I guess we are still learning about planet/moon formation in our Solar system. Cool stuff.

CCDs
Willard Boyle and George Smith take part of the Nobel Prize in Physics 2009 for their invention of CCDs. Widely used in astronomy and everyday cameras, CCDs have become a staple of modern life. The prize also highlights how private investment (when done smartly) may help fund new ideas. Boyle and Smith are just the latest recipients to have worked at Bell Labs (8 Nobel Prizes in total). Unfortunately, most of their research division is now closed.

Project Icarus

For $150 you can launch you own helium balloon (see details here). Although much of the credit should go for the slightly more expensive experiment carried out by Spanish students. I love cheap creativity. It's easy to be creative on a big budget, but some of the most interesting things come from having to build something out of nothing.

AIDS and Statistics
Results from AIDS tests in Thailand have been making the rounds in the news. I am a bit baffled by the statistics. Apparently 16,000 people from the general population were divided in two groups. Half were vaccinated while the other half received a placebo. They were then given condoms, taught how to prevent infection, and promised treatment in case the contracted the disease. The result that has been making the news is that 74 in the placebo got infected, while only 51 in the vaccinated group contracted the disease. Now, there is something that does not compute here. Couldn't we explain the difference simply by hypothesizing that 51 people in the vaccinated group had unprotected sex with partners with AIDS, while similarly 74 people in the placebo group had unprotected sex with AIDS carriers?. No need and no effect from the vaccine?. The only workaround is that they actually went out and proved that majority in both samples had unprotected sex with AIDS carriers. Otherwise, these results are bogus. I am not really sure how the results were computed. Am I missing something?. Anyone?.

Feynman
Bill Gates has put up a series of lectures given by Richard Feynman in a website called Project Tuva. This is part of Microsoft Research, so I think they are also trying to sell the idea of adding digital notes to videos (Youtube is already inserting ads in videos).

Yosemite judge wanted

The current Yosemite magistrate judge has resigned and the position is now open. Your job: to deal with misdemeanors in the park. Your office: somewhere near the picture on the right. Plus you actually get paid $160,000 a year. Well if you are a lawyer, this is the job for you. Hope they start looking for an in-residence astro type person soon.

TED 2009
Talks from the latest TED conference have been released. If you are not familiar with the concept, it puts together short talks (10-15 min) about various topics. The catch is that the talk has to be for a general audience and avoid busy viewgraphs. Some are more interesting than others but there might be something to learn there.

The geopolitics of astrophysics
Geopolitics have been floating around this month in different contexts. A weaker opponent challenges a larger one in order to call the attention of the world or the rap industry. A couple of weeks ago, Hao Liu and Ti-Pei Li decided to play the geopolitics of astrophysics by challenging the WMAP results. They claimed that there is a problem with the maps generated by the WMAP team that would alter some cosmological model parameters. So, it's really great that a David (Two Chinese researchers) challenges the results of a much stronger team (WMAP in this case). The problem is that the paper is really thin on the details, so I figure we will likely forget about it soon. The lesson, do challenge scientific results if you think that something is wrong but do it in a way where the readers can understand and reproduce your arguments. Otherwise, you'll basically be ignored by the rest of the world.

Moonwalk

Moonwalk has become one of the most commonly used words this month. Still 6 percent of Americans think the whole moon business was faked. Is it possible that we still have little faith in what humans can accomplish?. Have you ever flown on a plane?. Have you seen the pyramids?. Have you stood on the Golden Gate Bridge?.

Lou Reed and Laurie Anderson played Madrid recently. Naturally for this week’s tune we must take a walk on the wild side.

Ice cube

Ice Cube is an experiment under construction at the South Pole. Hence the name. Their main aim is to search for neutrinos, subatomic particles that are expected to be created during nuclear fusion (like that powering the sun), as well as in stellar explosions (supernovae and the like). Problem is that neutrinos are very hard to catch because they interact very weakly with human-made detectors. Ice Cube hopes to capture a neutrinos through their interactions with atoms in the ice sheets, which might eventually produce photons that instruments can actually detect. Debanjan Bose, one of the postdocs in our group, has received an offer to move to Belgium and join the neutrino search. We wish him well.
Most useless paperwork

Somehow I had missed this bit (in Spanish only). Thanks to Apuntes Científicos desde el MIT. Mexico held a contest to let its citizens nominate the most useless paperwork at the national, state and municipal levels. Usually bureaucracy tries to guard against such criticisms because it may be seen as a sign of weakness. (That’s my take on it). Otherwise, I see no reason for the lack of complaint boxes in every public office. The “box” could be visited routinely to identify serious problems. Now, will they eliminate the most useless paperwork or simply replace it with a new useless idea. We shall see.
Money-vation

nature.com is offering a number of cash rewards for readers who solve specific problems posted in this website. The basic argument is that money will provide extra motivation for people who seek a quick economic reward. The money prize isn’t new. But two questions come to mind: Will future research be economically driven?. Will be see ads plastered on the side of the Large Hadron Collider or the Large Synoptic Survey Telescope?.
