Researchers
are working on various ways of providing access
security that don't involve the burdensome
task of recalling passwords. Some are using
the recognition of previously-viewed pictures
to make passwords easier to remember. One
team is abandoning passwords altogether.

Rules
aim to get devices talking
There's no guarantee that future household devices
that are designed to be smart will be able to get
along with each other in order to seamlessly serve
our needs. Realizing the vision of ubiquitous computing
will require giving devices a means of cooperating
and even getting them to agree on basic concepts.
A set of game-like rules could help devices solve
these types of problems by themselves.
Access
patterns organize data
An information retrieval method that mimics the
way the brain links neurons causes data to organize
itself. The more people follow a path through a
set of data, the more visible the path becomes.
Atom-photon
link demoed
Atoms are relatively sturdy, as quantum particles
go, making them particularly suitable for storing
and processing quantum information. Photons, the
other hand, are hard to hold onto but good for transmitting
quantum information. Getting atoms and photons to
exchange information is crucial for many quantum
computer designs. The first verified atom-photon
entanglement shows that it's not so hard to do,
as long as you can accept a low success rate.
