As of May 16, 2012, USPS has changed part of their mailing rules and standards. Lithium batteries and cells (both rechargeable and non-rechargeable) are now not allowed to be shipped internationally or to any APO, FPO, and DPO locations. This means that mailers also cannot send out products that have lithium batteries inside of them, including tech gadgets such as cell phones, MP3 players, laptops, and digital camera.
After January 1, 2013, limited quantities may be allowed to ship out internationally, as long as "the batteries are properly installed in the personal electronic devices they are intended to operate."
This does not affect the current rules for mailing lithium products within the United States, and lithium batteries (and their corresponding technical products) may still be shipped out normally. However, for international shipping, mailers may have to resort to private carriers such as FedEx.

Well, it certainly looks like something the future would hold, doesn't it? Aerogel, also known as "frozen smoke" (can that name get any cooler?) is currently one of the world's lightest solids. It contains MWCNT - multi-walled carbon nanotubes, which are so small that thousands of them can fit on just one strand oh human hair.
Aerogel currently has many potential uses, ranging from detecting toxic substances to improving robotic surgery. One of these possible applications even includes something that could affect our daily lives: batteries.
Thanks to carbon nanotubes and the large surface area that they provide, aerogel is capable of storing vast amounts of energy. If used in conjunction with present-day batteries (whether they be lithium, alkaline, or other types), the aerogel could very likely increase the capacity that a single battery can hold.
"This has many potential applications and could really open up new areas to explore that we haven't even imagined yet," says Associate Professor Lei Zhai, who worked on the engineering team for aerogel. Along with Zhai were postdoctoral associate Jianhua Zou; University of Central Florida professores Saiful Khondaker, Sudipta Seal, and Quanfang Chen.
