Photo: Colorful cellular structures [18/12/2014] It is the most basic of ways to find out what something does, whether it is an unmarked circuit breaker or an unidentified gene - flip its switch and see what happens. New remote-control technology may offer biologists a powerful way to do this with cells and genes.'Radiogenetics' seeks to remotely control cells and genes - Read more

But a recent study shows that the intestines may in turn be protecting the brain, long before you are old enough to surf health and nutrition websites.Brain depends on gut bacteria for protection - Read more

Making Your Own End-of-Life Decisions: “All options of palliative care, pain management and continued life need to have been explained to the patient“

( Source: MEDICA.de )

[01/12/2014] How does a physician handle a patient, who wants to die and what rights do I actually have as a patient? Legal practitioners do not automatically answer these and other questions. We talked about this subject with MD-PhD Ralf Jox from the Institute of Ethics, History and Theory of Medicine at the Ludwig Maximilians University of Munich, Germany.Making Your Own End-of-Life Decisions: “All options of palliative care, pain management and continued life need to have been explained to the patient“ - Read more

Dopamine leaves its mark in brain scans

Graphic: Display of BOLD signal [26/11/2014] BOLD signals in functional magnetic resonance imaging do not always reflect what nerve cells are doing: Researchers use functional magnetic resonance imaging (fMRI) to identify which areas of the brain are active during specific tasks.Dopamine leaves its mark in brain scans - Read more

Complex jobs may protect memory and thinking later in life

Photo: Construction worker and architect [24/11/2014] People whose jobs require more complex work with other people, such as social workers and lawyers, or with data, like architects or graphic designers, may end up having longer-lasting memory and thinking abilities compared to people who do less complex work.Complex jobs may protect memory and thinking later in life - Read more

Clock for brain waves

Graphic: Network of nerve cells [21/11/2014] Oscillations of brain activity influence our attention and many other mental functions. Tatjana Tchumatchenko from the Max Planck Institute for Brain Research in Frankfurt and Claudia Clopath from Imperial College London have now developed a theoretical model that explains the origin of such oscillations in neural networks.Clock for brain waves - Read more
