The 14
nanometre process is used for the next generation of computer chips
following the 22 nanometre size. Intel had originally planned for these
to be released in late 2013, but due to production problems they would
be delayed until 2014.* Transistors are now reaching extraordinarily small sizes, prompting fears that Moore's Law will come to an end.
However, this trend in computing power will continue for some time to
come, thanks to a new generation of materials such as graphene.

Google Glass is launched to the public
Google Glass is an augmented reality head-mounted display, allowing hands-free access to the web.*
The product resembles normal eyeglasses where the lens is replaced by a
small electronic screen. It provides interaction via natural language
voice commands, as well as eye-tracking technology.*
A miniature gyroscope can tell the user's position and orientation at
all times. On the side frame is audio output, and a touch control pad,
while on top is a button for recording photos and videos with a built-in
camera. It is available to developers by 2013 and for the general
public by 2014.*
The design allows for integration of the display into people's
day-to-day eyewear. It is light and weighs less than most sunglasses. A
prototype unveiled in 2012 received criticism over the potential for
Google to insert advertising (its main source of revenue) into the
user's field of vision. However, the company denied it would use
adverts.
New MIT technology allows 3D image interaction
Massachusetts Institute of Technology graduate student Sean Follmer demonstrates in FORM technology on campus in Cambridge, Mass. Follmer, a researcher with MIT's Tangible Media Group, moves his hands in front of a depth-sensing camera which sends signals to a motorized pin screen in another location where a 3D image pops up to manipulate the red ball
Researchers See Through Walls With 'Wi-Vi'
Want Xray vision like the man of steel? A technology that lets you see behind walls could soon be built in to your cell phone. MIT professor Dina Katabi and graduate student Fadel Adib have announced WiVi, a demonstration of a technology that uses WiFi to allow a viewer to "see" a person moving behind a wall. (WiVi stands for "WiFi" and "vision.") Previous work demonstrated that the subtle reflections of wireless inter signals bouncing off a human could be used to track that person's movements, but those previous experiments either required that a wireless router was already in the room of the person being tracked, or "a whole truck just to carry the radio," said Katabi. -
The new device uses the same wireless antenna as is found in a cell phone or laptop and could in theory one day be embedded in a phone. [See also "WiSee Detects Your Gestures Using WiFi."]
The trick is canceling out all interfering signals – Wi-Fi doesn't just bounce off humans, but also walls, floors, and furniture. And those signals are 10,000 to 100,000 times more powerful than the reflections off a human body.
Katabi's wivi sends out two wireless signals, one of which is the inverse of the other. In what Katabi calls "interference nulling," the two signals cancel each other out unless they hit a moving target – such as a human.
"To silence the noise, we change the structure of the Wi-Fi signal so all the undesired reflections cancel," she said.
The device is meant to be portable so, for example, a person worried that someone was hiding in the bushes could do a quick scan for her personal safety.
WiVi could also serve as a high tech baby monitor or help Superman – or just cops – catch baddies.

Facebook launches Internet.org Initiative To Connect The Unconnected World
Facebook announced that it has partnered with Samsung, Nokia, Ericsson, MediaTek, Opera and Qualcomm to launch a project called Internet.org, to make the worldwide web available to two-thirds of the planet still not connected to the Internet with internet access via cheaper devices, better business models and better infrastructure.

Information and communications technology
Information and communications technology or information and communication technology (ICT), is often used as an extended synonym forinformation technology (IT), but is a more specific term that stresses the role ofunified communications and the integration of telecommunications(telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.
Information Technology
Information technology (IT) is a branch of engineering dealing with the use of computers and telecommunications equipment to store, retrieve, transmit and manipulate data.The Information Technology Association of America has defined IT as "the study, design, development, application, implementation, support or management of computer-based information systems" The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.
