Einstein
famously objected to quantum physics by saying
that God does not play dice with the universe.
The quantum world is filled with uncertainty,
so much so that getting a quantum computer
to generate random numbers would require an
impractical amount of computing resources.
A scheme for generating pseudo-random numbers,
however, makes for practical quantum dice
and could also play a key role in constructing
quantum computers.

Pressure shapes plastic
If you want to turn a plastic into a liquid you
usually have to apply heat. A material with a nanoscale
mix of hard and soft plastics, however, can be made
to flow at room temperature, given high-pressure.
The result could be cheaper and greener recycling.
Software
repairs itself on the go
Computer software has become more sophisticated
and we've come to rely heavily on it. This is a
problem because it's a challenge keeping complicated
programs running. The emerging field of self-healing
software aims to make programs take care of themselves.
A tool that models data structures helps computers
get the picture.
Nanoparticle
dyes boost storage
The idea of storing data in fluorescent dyes has
been around for a while, and researchers have been
trying to boost storage capacity by recording multiple
bits of information in a single spot using several
types of dye. The challenge has been finding ways
to keep dyes from interfering with each other. One
solution is layered particles five times smaller
than a blood cell. The result could make counterfeiting
much more difficult.
