The research team of Pavel Jungwirth from IOCB Prague has discovered a previously unknown mechanism by which short peptides are able to penetrate cells and, in principle, could serve as carriers of drug molecules.
Fluids exhibiting scaling behavior can be found in diverse physical phenomena, observed when these fluids reach a critical point. In a recent study published in EPJ B, Michal Hnatič from Šafárik University in Košice, Slovakia, and colleagues investigate the influence of ambient turbulent speed fluctuations in physical systems when they reach a critical point.
Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could enable future developments in LED lighting, quantum sensing, quantum communication and future quantum computing. The study has just been published in the renowned journal Nature.
Björn Alling, researcher in theoretical physics at Linköping University, has, together with his colleagues at the Max-Planck-Institut für Eisenforschung in Düsseldorf, completed the task given to him by the Swedish Research Council in the autumn of 2014: Find out what happens inside magnetic materials at high temperatures.
Previously, in order to study cell membranes, researchers would often have to freeze samples. The proteins within these samples would not behave like they would in a normal biological environment. Now, using an atomic force microscope, researchers can observe individual proteins in an unfrozen sample -- acting in a normal biological environment. This new observation tool could help scientists better predict how cells will behave when new components are introduced.
For the first time, scientists have created, from scratch, self-assembling protein filaments built from identical protein subunits that snap together spontaneously to form long, helical, thread-like configurations. Protein filaments are essential components of several structural and moving parts in living cells, as well as many body tissues. Being able to design and build protein filaments could allow for engineering novel materials for nano-electronics or scaffolds for new diagnostic tests.
Laser-based 'optical tweezers' could levitate uranium and plutonium particles, thus allowing the measurement of nuclear recoil during radioactive decay. This technique, proposed by scientists at Los Alamos National Laboratory, provides a new method for conducting the radioactive particle analysis essential to nuclear forensics
Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important insights about the development of other planets and their potential to support life.
The international scientific team developed a new method for measuring the response of crystals on the electric field. The results a collaborative research done at the European Synchrotron Radiation Facility (ESRF) were published in the Journal of Applied Crystallography and appeared on the cover of the October issue.
Researchers at EPFL's Institute of Chemical Sciences and Engineering have developed a photocatalytic system based on a material in the class of metal-organic frameworks. The system can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and used further.
