At the Campus Vienna Biocenter research has begun into environmental stress-induced changes to the plant genome supported by the Austrian genome program (GEN-AU). A EUR 1.3 million budget has been allocated to the three-year project. Two task groups at the University of Natural Resources and Applied Life Sciences and five at the Campus will investigate how extreme environmental conditions impact on the plant genome. It is also hoped that evidence will be found to support the hypothesis that inheritable environmental adaptations of living organisms do not occur randomly. Confirmation of this would revolutionise current thinking about heredity.
But surely everyone knows mutations happen by chance, don’t they? Researchers at the Campus Vienna Biocenter are not so certain, and this is precisely the question a three-year project there will now address. A total of 17 scientists will be looking into the effects of environmental stress on the genome of the model plant Arabidopsis with financial support from the Austrian genome program (GEN-AU), a program funded by the Ministry of Education, Science and Culture. They will also investigate whether stress reactions may contribute to further changes in the genome. If that were the case it would show that mutations do not simply arise randomly, but are also influenced by the plant metabolism – and it would be time to re-write the textbooks.
Prof. Heribert Hirt of the newly established Dept. of Plant Molecular Biology at the University of Vienna commented: "In the early 19th century it was widely believed that the adaptation of living organisms to their environment was a systematic process, and could be passed on to offspring. Darwin and modern genetics overturned these assumptions. According to them, inheritable adaptations are random. A few of them are beneficial, and are naturally selected. It is now known that random adaptations are caused by mutations. However for some time now there has been evidence that mutations are by no means as random as was thought. In lower organisms such as bacteria, in particular, it has been shown that mechanisms leading to an increased incidence of mutations are activated by certain types of stress."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
