ForscherInnen der Universität Wien gelingt Manipulation von Nanostäbchen

Einem internationalen Team, bestehend aus ForscherInnen der Universität Wien, der Tel Aviv University und der Universität Duisburg-Essen, ist es erstmals gelungen, Nanostäbchen zu präparieren, mittels Laserlicht ins Vakuum zu heben, ihre Bewegung mit hoher Zeitauflösung zu verfolgen, zu beeinflussen und zu verstehen. Die im Fachjournal Nano Letters publizierten Ergebnisse öffnen das Fenster zu einer neuen Klasse von Nanopartikeln an der Grenze zur Alltagswelt.

New Mouse Reference Library Should Speed Gene Discoveries

Genetic information provided by a large group of specially designed mice could pave the way to faster human health discoveries and transform the ways people battle and prevent disease.

In 15 papers published Feb. 16 in the Genetics Society of America journals Genetics and G3:Genes/Genomes/Genetics, researchers from North Carolina State University, the University of North Carolina at Chapel Hill, The Jackson Laboratory and other universities and labs across the globe highlight a new genetic resource that could aid development of more effective treatments for any number of human diseases.

A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena.

Energy carried in ordinary waves, like those seen on the ocean near a beach, quickly disperses. But the energy in the coupled pendulums and in compressed elastic film concentrates into different kinds of waves, ones with discrete packets of energy called “solitons.” (more…)

*Plant lineages with multiple copies of their genetic information face higher extinction rates than their relatives, researchers report in Science magazine.*

While duplication of hereditary information is a relatively rare event in animal evolution, it is common in plants. Potatoes, coffee, bananas, peanuts, tobacco, wheat, oats and strawberries, to name but a few, all carry multiple copies of their genetic material, in a condition called polyploidy.

In contrast, most animals including humans are diploid, meaning an individual carries only two copies of each chromosome, the carriers of genetic information, one from each parent. (more…)
