Novel methods of measuring magnetic fields outside the head give further insights to the functioning of the human brain. In his doctoral thesis “Estimating Neural Currents from Neuromagnetic Measurements”, Kimmo Uutela developed new methods for finding electrical activity of the brain, which enable easier identification of different brain areas. The Finnish Association of Graduate Engineers (TEK) and the Engineering Society in Finland (TFiF) honoured Uutela’s work with their joint doctoral thesis award.
Uutela developed two methods, based on magnetic measurements, for estimating electric activity of the brain. Research was carried out at the Low Temperature Laboratory of Helsinki University of Technology. One method is a multidipole model applying genetic algorithms and the other is a minimum current estimate method. These mathematical methods make it easier to locate brain areas which operate simultaneously, and are useful tools for research purposes as well as for the planning of neurosurgery, for example.
“Both estimation methods are automatic making the source estimation faster and less subjective,” explains Uutela. “Also, the results of the minimum current estimate are in a format that can be easily combined with results of other brain imaging modalities and over different subjects.”

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
