Low-Energy Neutrinos Detected In Real Time 73

Roland Piquepaille sends us word of first results from the Borexino detector in Italy, where an international team of more than 100 researchers has detected low-energy solar neutrinos for the first time. These results confirm recent "theories about the nature of neutrinos and the inner workings of the sun and other stars." In particular, it's now almost certain that neutrinos oscillate among three types, namely electron, muon, and tau neutrinos. The Borexino detector lies almost a mile underground near L'Aquila, Italy, and it sets new standards in the purity of the materials used in its construction.

iluvcapra writes: AT&T has announced that it will no longer by itemizing individual network accesses on its bills. This practice had lead to some humorous situations and a lot of wasted paper, causing even casual iPhone users to receive 20 or 30 page bills with long lists of data downloads (all, of course, covered under their plan).

Submission + - Multiformat Listening Test at 64kbps

Anonymous writes: The Hydrogenaudio community is conducting a "Public, Multiformat Listening Test" (http://www.listening-tests.info/mf-64-1/) to see which codecs (AAC, WMA Pro and Vorbis) provide the best sound quality when compressing samples at 64kbps.

This test is open until the 5th of August and seems to be much, much harder than what one would expect, even for experienced developers of sound codecs, at bitrates that the public would find "too little", as the comments on the thread at the discussion forums (see: http://www.hydrogenaudio.org/forums/index.php?show topic=56397).

Do you think that you have good ears? That 64kbps is "too little"? Then try it for yourself and participate. Your participation will help us improve the codecs so that they are even closer to being "transparent" at such "low" bitrates.

NASA's Future Inflatable Lunar Base 203

Roland Piquepaille writes "If you think that future NASA's moon camps need to have a science fiction look, you might be disappointed. Today, NASA is testing small inflatable structures. In fact, if these expandable 'tents' receive positive reviews, astronauts will 'camp' on the moon as early as 2020. These 12-foot (3.65 meter) diameter inflatable units could be used as building blocks for a future lunar base. Right now, a prototype is tested at NASA's Langley Research Center. But NASA also wants to test other inflatable structures in the not-too-friendly environment of the Antarctic next year. Still, it's too early to know if NASA's first habitable lunar base will use inflatable or rigid structures."

Camera Phones Read Hidden Messages in Print 126

pikine writes "As reported by BBC News, Fujitsu has developed a technology that encodes 12-bytes of information in a printed picture by skewing yellow hue, which is difficult to discern by human eye but fairly easy for camera phones to decode using software written in Java." The first target uses are promotional contests and competitions, not entirely unlike those game pieces that need to be viewed through a colored filter.

Storing Wind Power In Cold Stores 242

Roland Piquepaille writes "According to Nature, a European-funded project has been launched to store electricity created from wind in refrigerated warehouses used to store food. As the production of wind energy is variable every day, it cannot easily be accommodated on the electrical grid. So the 'Night Wind' project wants to store wind energy produced at night in refrigerated warehouses and to release this energy during daytime peak hours. The first tests will be done in the Netherlands this year. And as the cold stores exist already, practically no extra cost should be incurred to store as much as 50,000 megawatt-hours of energy. Here are additional details and a picture illustrating this brilliant idea."

The Best Graphing Calculator on the Market? 724

aaronbeekay asks: "I'm a sophomore in high school taking an honors chem course. I'm being forced to buy something handheld for a calculator (I've been using Qalculate! and GraphMonkey on my Thinkpad until now). I see people all around me with TIs and think 'there could be something so much better'. The low-res, monochrome display just isn't appealing to me for $100-150, and I'd like for it to last through college. Is there something I can use close to the same price range with better screen, more usable, and more powerful? Which high-tech calculators do you guys use?"

Journal Journal: Anonymous comments 2

I tend to get mod points with decent frequency, and often want to post and mod the same discussion. I'm perfectly happy to post the comments anon, to avoid the whole karma thing, but it would be nice if people could check that they still were written by me. Thus, this journal entry: in it, I'll note which anonymous comments are mine (and link here from the comments.)


Submission + - Google Delays Payments to improve 2005 books

An anonymous reader writes: I got the following from google after complaining about my adsense earnings being rather late. They are putting november earnings on a January payment instead of december. My colocation bill normally posts around the 2nd of the month, two weeks after Google pays me. This time sufficient funds wont be in the account and I am actually leaving the colocation facility due to this. Google is continuing to lose sight of their 'dont be evil' motto.

Other publishers are complaining as well and were also told they are not being paid until next month as well. Google is telling everybody January 5th, which is about two weeks later than normal.

Hi ******, Thanks for your email. I apologize for the delay in EFT processing due to
the holidays. Please rest assured that your December payment (for Nov.
1-30 earnings) is currently in progress and will be sent to you soon. Once
it is issued, you should see the 'Payment' link posted to your Payment
History page.

I understand that your payments may have arrived earlier in the past.
However, as a general rule (for EFT), your payment should arrive in your
account by January 5th, at the latest.
Please let me know if you haven't received your payment by January 5th. I
appreciate your continued patience and understanding in this matter.

Best regards,

Submission + - How do slashdotters manage email on their laptops?

dotancohen writes: "I'll soon be getting a new Dell laptop that'll be running Fedora Core 5 or 6. I need to access the email stored on my home box from the laptop, and also to read new email sent to me while I'm not home (and the home box is shut down). If I run an IMAP server at home, then I can't read the mail when the home box is down. But if I pull from the POP3 server (and leave the mail on the server) then I won't be able to sort and file the mail while on the go. Is there anyway to sync the mail accounts between two linux boxen, assuming that I'm using the same mail client? I currently use Kmail, but I might switch to Eudora in April/March when it becomes available for Linux.

Thanks in advance."

Submission + - iTunes Visits Skyrocket 413% On Christmas Day

An anonymous reader writes: Hitwise today announced that the market share of visits to the iTunes website was up 413 percent on Christmas Day 2006 (December 25, 2006) versus Christmas Day 2005 as new iPod owners flocked to the web to download iTunes. The market share of visits to Zune.net showed an increase of 1,030 percent on December 25, 2006 versus the previous Monday (December 18, 2006). However, this strong initial performance was overshadowed by the iPod.
