" On March 12, 1989 Tim Berners-Lee, while working as a contractor at the CERN laboratories in Switzerland, submitted Information Management: A Proposal,
which sparked the greatest advance in information technology since
Gutenberg invented the printing press. At the time, it was just a way
for CERN scientists to share data, but a quarter of a century later,
it’s grown from a curiosity into a necessity without which our world can
no longer function." [...]

NANOTECHNOLOGY- Optical nano-tweezers allow for manipulating molecules, other nanoscale objects
"Researchers at the the Institute of Photonic Sciences (ICFO) in
Catalonia have invented nano-optical tweezers capable of trapping and
moving an individual nano-object in three dimensions using the force of
light.
“This technique could revolutionize the field of nanoscience since,
for the first time, we have shown that it is possible to trap,
3D-manipulate, and release a single nano-object without exerting any
mechanical contact or other invasive action,” said Romain Quidant, ICREA
Professor and leader at ICFO of the Plasmon Nano-Optics research group." SOURCE: kurzweilai.net

NEXT-GEN ELECTRONICS- Ultra-thin capacitors could acclerate development of next-gen electronics
"Takayoshi Sasaki and colleagues note that current technology has
almost reached its limit in terms of materials and processing, which in
turn limits the performance that manufacturers can achieve. In response,
researchers have gone to the nanoscale, but “nanocapacitors” are not
easy to make. They require harsh, difficult-to-use methods and even
then, they may not work that well.
Layers of different types of oxide nanosheets
So Sasaki’s team developed an easier way to make high-performance
“ultrathin” capacitors. The researchers found that they could use gentle
techniques and mild conditions to create a sandwich consisting of
layers of two different types of oxide nanosheets to produce an
ultrathin capacitor.
In addition, the new capacitor has a capacitance density of as high
as ∼27.5 μF (microfarads) per square centimeter, which is approximately
2000 times higher than those of currently available commercial products."
