Efficient technique enables thinking
Scientists at the Max Planck Institute for Neurobiology in Martinsried have found a completely new, faster technique nerve cells use to evaluate the quality of the cells they contact in a very time- and energy-saving way.
Instead of synapses (which require up to two days to become fully functional), neurons use calcium for thinking.
When a lengthening extension encounters a neighboring cell, a release of calcium is triggered at its base. This calcium signal then acts like a stop sign: the extension immediately ceases to grow. At the same time, this signal already contains all the important information about the quality of the new contact: the contact only remains intact if the calcium signal is significantly higher than the surrounding calcium level of the cell. Otherwise, the extension withdraws and the nerve cell searches for a suitable partner cell at another point.

NeuroVista, Emerging from Stealth Mode, Unveils Technology to Predict Epileptic Seizures
Xconomy.com, July 28, 2008
Researchers at NeuroVista are developing an implantable device designed to predict a seizure before it happens and warn a patient to get ready.
In their system, an implanted telemetry device receives brain wave data and transmits it to a receiver, where proprietary mathematical algorithms transform the information into a real-time warning system.
The device could also be a warning system for other neurological disorders that can have unpredictable flare-ups, like migraine headaches or severe depression. The company plans its first feasibility clinical trial in 2009.

Surveillance made easy
New Scientist news service, Aug. 23, 2008
Governments around the world are developing increasingly sophisticated electronic surveillance methods in a bid to identify terrorist cells or spot criminal activity.
German electronics company Siemens has gone a step further, developing a complete «surveillance in a box» system called the Intelligence Platform, pooling data from sources such as telephone calls, email and internet activity, bank transactions and insurance records. It then sorts through this mountain of information using software that Siemens dubs «intelligence modules.»

A study at Loughborough University, England, found that it takes an average of 64 seconds to recover your train of thought after interruption by email, so people who check their email every five minutes waste 8 1/2 hours a week figuring out what they were doing moments before.
