Using brain waves to control screen cursor movements, rather than moving a mouse by hand, seems like science fiction! Yet such direct control over our environment is an integral part of the development work being undertaken by participants in the Presencia project.
The IST project Presencia is not due for completion until October 2005, yet project researchers have already developed a working brain/computer interface able to provide direct control of computers. The method is primitive as yet, but has been demonstrated to work. Users experiencing the system have a cap of electroencephalogram (EEG) electrodes placed upon their head. These electrodes are then connected to a pocket PC that records the EEG data or brain waves in real-time. Sat in front of the PC screen, users imagine moving the cursor to the left and then to the right, without actually moving their hands.
The whole procedure is repeated 20 times for each different movement while the PC records the volunteer’s brain wave data throughout. With the Presencia software trained to recognise the volunteer’s brain wave patterns, activation of a control signal then allows the user to move the on-screen cursor either to the left or to the right, simply by imagining the movement!

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
