Scientist closes in on creating a superlens

With a superlens microscope, everyday people would be able to see minute details of tiny o...



One day, you may have a microscope on your smartphone camera that's as powerful as a scanning electron microscope. This may be due to the research being conducted by Durdu Guney, an assistant professor of electrical and computer engineering at Michigan Technological University.

Sony's VAIO T13 Ultrabook coming to the US this month with Ivy Bridge in tow, prices start at $800


DNP EMBARGO Sony's VAIO T13 Ultrabook comes to the US with Ivy Bridge in tow, prices start at $800

after Sony Ultrabook fun of her for the first time at CES, what happened next was a bit disappointing: it was announced for the European market ... with the latest generation of processors, Sandy Bridge. Now, however, the company is back with two good news: the 13 inch VAIO T13 went to the U.S. as well, and the latest service pack Intel Ivy Bridge, after all. (If it is expected that the T11 11-inch, it seems that is not marketed in the country.) As a reminder, the T13 is trendy in matt silver aluminum, has a 13-inch ( 1366 x 768) screen and weighs about 3.5 pounds, a bit heavy for a 13-inch Ultrabook. On the bright side, only 0.71 inches thick chassis hosts a healthy selection of ports including USB 3.0 and 2.0, HDMI, Ethernet, VGA and an SD slot. The equipment you will not find? A backlit keyboard.

Even more interesting is the cost: if you think Sony products also sit in the cache of the brand, the T series starts at $ 800, almost as low as prices fell to Ultrabook times. In the entry level, comes with a Core i5, 4 GB of RAM and a 500 GB hard disk drive with a 32 GB solid state to reduce startup time - fairly typical specification for the money . Willing to spend more? You can maximize with a Core i7 and SSD of 256 GB Expect to arrive in the month, and now, feel free to browse the glossy press photos below.
