Fishing can cause slowly reversible changes in gene expression

Cohort after cohort, fishing typically removes large fish from the population and can lead to rapid evolutionary changes in exploited fish populations. A new study from the University of Turku, Finland, shows that removing ...

Researchers discover self-assembling 2-D and 3-D materials

Self-assembly of matter is one of the fundamental principles of nature, directing the growth of larger ordered and functional systems from smaller building blocks. Self-assembly can be observed in all length scales from molecules ...

Researchers develop DNA-based single-electron electronic devices

Nature has inspired generations of people, offering a plethora of different materials for innovations. One such material is the molecule of the heritage, or DNA, thanks to its unique self-assembling properties. Researchers ...

Chains of nanogold – forged with atomic precision

Researchers at Nanoscience Center of University of Jyväskylä in Finland have succeeded in producing short chains and rings of gold nanoparticles with unprecedented precision. They used a special kind of nanoparticles with ...

Fishing erodes natural size variation

Fishing typically removes the large individuals from the population. Over time, this not only leads to evolutionary shrinking of fish but it also erodes natural trait variability in fish stocks. This was demonstrated in a ...
