A team of researchers from the University Hospital of Grenoble (CHU – Inserm U647) and the ESRF1 has found a new treatment that improves the survival of rats with high-grade gliomas.
This research was carried out at the ESRF Medical Beamline. It showed that after a year of this treatment, three rats out of 10 were considered cured, whereas without treatment, all would be dead. The results have just been published in the scientific journal Cancer Research. A glioma is one of the most frequent brain tumours in human adults, and it is not curable. Clinical trials on humans are planned for the near future.
Today, the median survival for patients with glioma is less than a year. Around 5 to 10 adults out of 100.000 suffer from this brain tumour. Traditional radiotherapy using hospital X-rays only has a palliative effect because gliomas are some of the most radio-resistant human tumours. Chemotherapy is ineffective most of the time. Several therapeutic techniques have been developed over the last years using animal models, but none has had such successful results as this new treatment with cis-platinum combined with monochromatic synchrotron x-rays. This new technique combines chemotherapy with radiotherapy in such a way that both techniques are effective when associated.

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...
