SCIENTISTS IVENT "WORLDS LIGHTEST" MATERIAL -PcMag

Researchers have created a material that's so light it can rest comfortably on a dandelion seed head without disturbing the fluffy, delicate structure of the plant. The "ultralight metallic microlattice" invented by scientists at UC Irvine, HRL Laboratories, and Caltech is described in the Nov. 18 issue of Science.
The new material is 100 times lighter than styrofoam, according to reports. The secret to its lightness is a cellular architecture fabricated from hollow tubes that supports a material structure that is in reality 99.99 percent air, according to the research team that built it.
That means the material's density is less than one-thousandth that of water. And the stuff is pretty resilient as well—researchers said that when squashed to half its height, the material rebounds 98 percent of the way back.


"The trick is to fabricate a lattice of interconnected hollow tubes with a wall thickness 1,000 times thinner than a human hair," lead author Tobias Shandler of HRL said, according to the Los Angeles Times.
The material seen resting on a dandelion seed head in the picture above is 90 percent nickel, according to the Times, but Bill Carter, manager of the architected materials group at HRL, told the newspaper that it can be made out of other materials as well.
One UC Irvine researcher involved with the project suggested the ultra-lightweight material might be used for impact protection, and might have applications "in the aerospace industry, acoustic dampening, and maybe some battery applications," according to the Times.
The material behaves somewhat like a feather when dropped, floating to the ground, Carter told the paper.
"It takes more than 10 seconds, for instance, for the lightest material we've made to fall if you drop it from shoulder height," he said.

7 Things You Need to Know About Google Music -PcMag

Google just made its music cloud service, Google Music, available to all, and it's mostly self-explanatory: You go to music.google.com and start uploading or purchasing music that you can then listen to on your computer, or on your Android phone, Google TV, or iPhone. Just like iTunes, right? Well, not really. Maybe it's not so straightforward after all. Here are a few pointers that may help clear out some of the possible sources of confusion:

1. It can automatically back up iTunes and most other music flies. When you set up the service, you can tell it to upload your iTunes library, your Windows Media Player library, or any file folders you designate. The service supports more file types than competitors iTunes and Amazon Cloud Player. This  includes not just the MP3 and AAC formats those support, but also WMA, OGG, and FLAC. The latter are saved as 320 Kbps, even if your originals are of higher quality.

2. It's two separate sites. Google Music is the player and library, but you buy music on the Android Market site—whether or not you ever use any Android device. From the Google Music site, you can also download an app, Music Manager, that scans your PC or Mac for music files and upload it to your cloud-based music locker. The Android Market is where you browse, preview, and purchase new music, which then appears on your Google Music pages or in your Android Music app.

3. You can't download songs to another computer unless you bought them on Google Music. iTunes Match and Amazon Cloud Player let you download stored music to any computer or compatible mobile device.

4. Some Android devices fully support it, some don't. There is, of course, an Android app, but that hasn't yet been updated with all the new features, and some phones and tablets still don't see music in the Android Market app yet. The whole point of Google Music is to finally give Android mobile users an equivalent to the iTunes services enjoyed by iPhone and iPad users. Google states that this will be updated within days, but it's unclear which phones and tablets' Android versions will be updated on what schedule. Some Android phones and plans, starting with T-Mobile, will even let you pay for music through your phone bill.

5. There's no official iPhone app, but music.google.com works on iOS devices. The Google Music site is even formatted well for iPhone screens. You can listen to any music in your Google Music cloud locker and even buy music from the separate Android Store, but you can't back up music on the iOS device to Google Music. Nor can you download music bought in the Android Music store to the iPhone directly (see #1 for how to do it indirectly).

6. There's tons of free music. But you need to give Google your credit card information even for the free stuff. This could be a concern to those who worry about Google profiling them.

7. You can only share purchased songs to Google+. If you do so, anyone following your Google+ profile will be able to stream the full song once. A Buy button is prominently displayed. Songs you uploaded but didn't buy at the Android Market don't get this treatment.

THANKSGIVING

Let us give thanks to God above,
Thanks for expressions of His love,
Seen in the book of nature, grand
Taught by His love on every hand.

Let us be thankful in our hearts,
Thankful for all the truth imparts,
For the religion of our Lord,
All that is taught us in His word.

Let us be thankful for a land,
That will for such religion stand;
One that protects it by the law,
One that before it stands in awe.

Thankful for all things let us be,
Though there be woes and misery;
Lessons they bring us for our good-
Later 'twill all be understood.

Thankful for peace o'er land and sea,
Thankful for signs of liberty,
Thankful for homes, for life and health,
Pleasure and plenty, fame and wealth.

Thankful for friends and loved ones, too,
Thankful for all things, good and true,
Thankful for harvest in the fall,
Thankful to Him who gave it all.

This poem by Lizelia Augusta Jenkins Moorer, an African-American poet was writen at the turn of the 20th century. Her generous, hopeful view of Thanksgiving is made even more remarkable by the suffering and discrimination she endured as an African-American in the late 19th and early 20th century.
