Impaired cellular force transmission a cause for valvular heart disease

About three per cent of the world’s population is affected by valvular heart diseases. It is also the most common cause of heart surgery, as no drug-based treatment is available. Recent research has shed light on the molecular mechanism on valvular disease that is caused by a genetic mutation in Filamin gene. The result of the research will help to further investigate the mechanism by which the medical condition progress and to develop new treatments.

New information to understand regulation of muscle function in muscle dystrophy patients

Scientists from the University of Jyväskylä, Finland, and from University of Cambridge, United Kingdom, have found new functions and structural details of muscle attachment structures. The research is important for the basic understanding of regulation of muscle function for instance in muscle dystrophy patients and muscle adaptation to physical activity and sports.

Molecular memory can be used to increase the memory capacity of hard disks

Researchers at the University of Jyväskylä have taken part in an international British-Finnish-Chinese collaboration where the first molecule capable of remembering the direction of a magnetic above liquid nitrogen temperatures has been prepared and characterized. The results may be used in the future to massively increase the storage capacity of hard disks without increasing their physical size.

High-resolution imaging of nanoparticlesurface structures is now possible

Using scanning tunnelling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. This was the finding of joint research between China and Finland, led in Finland by Academy Professor Hannu Häkkinen of the University of Jyväskylä. The research was recently published in the prestigious Nature Communications series and the publication was selected by the journal editors to the journal’s monthly collection of highlighted papers.

A novel nanoactuator system has been developed

Researchers at University of Jyväskylä (Finland) and University of Tampere (Finland) together with BioNavis Ltd (Finland) have developed a novel nanoactuator system, where conformation of biomolecule can be tuned by electric field and probed using optical properties of gold nanoparticle.

How to melt gold at room temperature

As tension rises unexpected things can happen. This is also true for gold atoms. Researchers, have, for the first time, managed to make the surface of a gold object melt at room temperature.

Tick-borne disease is not just Lyme

A study recently published in Scientific Reports discovered that 65% of Lyme disease patients irrespective of their disease stage respond to several microbes. As a consequence, the authors have demonstrated that microbial infections in individuals suffering from Lyme disease do not follow the "one microbe, one disease" status-quo. Moreover, the probability that Lyme disease patients would respond to multiple microbes associated with the tick-borne disease is an astounding 85 %.

Nano becomes visible in Finland, 9.–10.10.2018

The Nanoscience Center of the University of Jyväskylä, Finland, organizes the international Nanoscience Days conference on 9th – 10th of October 2018 in Jyväskylä. A traditional event organized more than ten years now, and provides an interdisciplinary forum for presenting and discussing fundamental and technological developments. Approximately 200 international researchers and students are attending the conference.
