model maps congestion

The
commuter's dilemma -- drive around the city
or cut through and risk traffic jams -- is
at the heart of a mathematical model that
sheds light on all manner of networks, including
nutrient pathways in fungi, manufacturing
supply chains, and the Internet. The model
shows that things move better when there is
a carefully calibrated penalty for going through
the hub.

A short history of TRN
Technology Research News was begun and initially
funded by a small group of journalists. We like
to think of ourselves as akin to farmers. We sift
through the large number of science and technology
research developments and discoveries and bring
you what we think are the most important discoveries
of the day...
Fingernails
store data
The idea of implanting computer chips in people
has gotten a lot of attention recently. One group
of researchers has shown that you don't need a chip
to store data in the human body. The key is treating
fingernails like compact discs.
Quantum
crypto scheme doubly fast
Quantum cryptography has established itself as a
key technology for securing communications, but
it remains relatively slow. A radical approach promises
to double data rates. Key to the method is tossing
aside one of the foundations of traditional quantum
cryptography.

It Works: Internet Structure
Following the links yields both quantity and quality.

Baited
molecule fights cancer
Baiting an anticancer drug with a vitamin that cancer
cells crave is a promising method of fighting cancer.
The trick is using a highly branched molecule to
put the bait on the hook.
Bacteria
drive biochip sensor
Connecting bacteria to electronics proves to be
a good way to quickly and cheaply detect contaminated
water.
System
brightens dark video
A virtual camera promises to fix all those underexposed
home videos. The trick is leveraging time and space.
Micro
fuel cell packs power
A small fuel cell packs more power than today's
methane models by using energy-rich propane.
