EU-funded project named `MICROBE DIAGNOSTICS` has developed new tools that enable more extensive and rapid analysis of our gut microbiota than has been possible earlier.
These new methods are based on the unique genetical codes each microbe contains. The project has developed 16 new testing devices, so called oligonucleotide probes. These probes are able to describe a more varied set of organisms that live in our microbiota than previously has been recognised by scientific methods. With these methods, researchers in the project have found previously unfamiliar bacteria present in the human gastrointestinal tract. A further improvement in this methodology is applying flow cytometry, which can rapidly analyse a large number of samples reliably.
The reason for developing these new tools is that we still have relatively little information about the variety of different organisms that live in our microbiota. There seems to be great variety among people, but what is the significance of this variation is not yet known. Also the used methods have been slow to apply. This lack of basic understanding is an obstacle if we want to modify the microbiota and increase the amount of beneficial microbes and find relationships between gut microbiota and diseases. Learning to know what the microbes are is not enough, however. In addition, we have to further learn what is their function in the body. The new knowledge can be used to identify the components of normal gut microbiota that may play a part in onset of inflammatory bowel disease (IBD). With this enhanced knowledge we may be able to prevent the disease or improve its treatment with beneficial probiotic microbes.

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...
