Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
Scientists, including Brown University geologists and students, have completed the first global geological map of Ganymede, Jupiter’s largest moon and the…
Described in a new paper,* the NIST/JPL array-on-a-chip easily identifies the position of the exact detector in a multi-detector system that absorbs an…
Modern electronics relies on utilizing the charge properties of the electron. Using lasers and magnetic fields, atomic systems can be engineered to have…
Protein trans-splicing catalyzed by split inteins is a powerful technique for Assembling a polypeptide backbone from two separate parts. As shown in the figure, the N and C terminal intein fragments associate and fold into the active domain thereby linking the
flanking sequences with a peptide bond. However, split inteins with robust efficiencies and short fragments suitable for Peptide synthesis are rare and have mostly been artificially created exhibiting poor to moderate coupling efficiencies only.
Just as ember spreads through a piece of coal, heat principally diffuses at a constant rate. The corresponding physical law known as Fourier’s law was already…
An international team of astronomers, led by Imperial College London, used a new way of combining data from the two European Space Agency satellites, Planck…
So, when signals bounced off the lunar surface returned surprisingly faint echoes on full moon nights, scientists sought an explanation in reason rather than…
Scientists of the Westfaelische-Wilhems University Muenster and Sensient developed dopants for Organic Light Emitting Diodes (OLED). The tri and bi-dental platinum (II) complexes with phosphite or dianionic NNC/NNN ligands are triplet emitters with excellent quantum efficiencies.
OLEDs consist of electro-luminescent substances, embedded in a polymer matrix. To emit exzitones, an electric current, triggered energy transfer is needed. Useful electroluminescent dopants are metal complexes like platinum complexes. The quantum efficiencies depend on the electronic behavior of the ligands used.
Therefore useful and efficient substances like P-Phos are required.
Mutations in the lysosomal enzyme ß-glucosidase 1 (GBA1) cause Gauchers disease, the most common lysosomal lipid storage disease in humans. When GBA1 is absent or impaired, glycosylceramide (GlcCer) accumulates within the macrophage lysosomes, leading to liver and spleen enlargement, bone lesions and in the most severe cases, impairment of central
nervous system functions.
In the past, this was possible only at much lower temperatures, typically in the microkelvin range. The coupling of nuclei and electrons creates a new state of…
Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory — how an organism can create…
Production process of wood composites combining hot air and hot steam. This reduces the production time, production line and enables the use of any current binder.
In a collaboration scientists from the University of Göttingen and of the University of Bielefeld developed a procedure for the production of recombinant isolated active eukaryotic full lenght C-alpha Formylglycine-Generating Enzyme (FGE) in selected eukaryotic cells for biotechnological and therapeutic uses.
Innovative Furane-Pyrene derivatives to be used for organic light emitting diodes (OLEDs) have been synthesized at the University of Göttingen. They show an increased efficiency of the blue emission spectra and stability during doping and de-doping in polymer films.
